The presence server may determine that a third UE is another instantiation of the same device as the first UE, and that the third UE is a lesser-capable device (e.g., non-Universal Profile enabled) with respect to the first UE. The presence server may send a notify message including a capability indicator associated with the third UE to the second UE, and/or the notify message may omit a capability indicator associated with the first UE.
Systems, devices, and techniques described herein relate to handover between Non-Standalone (NSA) and Standalone (SA) networks. An example method includes receiving, from a User Equipment (UE), a measurement report indicating that a signal threshold has been satisfied. In response to receiving the measurement report, handover of a communication session from a first core network to a second core network may be initiated. A message confirming that the communication session has been handed over from the first core network to the second core network can be received. In response to receiving the message, handover of the communication session can be initiated between a single radio bearer associated with a first Radio Access Technology (RAT) and a dual radio bearer associated with the first RAT and a second RAT.
Systems, devices, and techniques described herein relate to intelligently selecting a connectivity mode. At least one first network characteristic of a first radio link utilizing a first radio technology may be determined. A connectivity mode may be selected based on the at least one first network characteristic. The connectivity mode can be selected from among a dual connectivity mode utilizing the first radio link and a second radio link utilizing a second radio technology, a first single connectivity mode utilizing the first radio link, and a second single connectivity mode utilizing the second radio link. The device may be connected to the first radio link and/or the second radio link according to the selected connectivity mode.

Systems, devices, and techniques described herein relate to selectively implementing an expedited retransmission time. In some examples, a call setup message is transmitted to a first network system associated with a first network access technology. A transfer request may be received from the first network system. The transfer request may indicate handover or redirection to a second network system associated with a second network access technology. Upon expiration of the expedited retransmission time after receiving the transfer request, the call setup message can be retransmitted to the second network system.
A system, e.g., associated with a telecommunications network, includes first and second registry devices. In some examples, the first registry device receives a registration message. The second registry device receives a query specifying a type (NFType) of a network function and forwards the query to the first registry device based at least in part on the NFType. The first registry device responds, and the second registry device forwards the response. In some examples, the query specifies a service class and the second registry device forwards the query based at least in part on the service class. In some examples, the first registry device sends an indication of the registration to the second registry device, and the second registry device responds to the query based at least in part on the received indication and on at least one of an NFType or a service class of the query.
A telecommunication system can include routing devices, a Quality of Service (QoS) controller, a policy-management device, and a flow-management device. The QoS controller or flow-management device can receive a request from a terminal to create a specialized flow (SF), e.g., for a non-audio, non-video media type. If the request is associated with an authorized user, a setup message can be sent comprising a QoS indicator. The system can create the SF permitting data exchange between the terminal and a routing device. The SF can have QoS characteristics associated with the QoS indicator. In some examples, the terminal can receive network-address information, determine an associated network resource, and send a flow-request message indicating a non-audio, non-video media type. The terminal can then exchange data on the network port with a peer network terminal.
In some examples, a terminal can establish wireless communication with a base station. The terminal can determine a challenge, transmit the challenge, receive a response, and determine that the response is valid. The terminal can, in response, establish a secure network tunnel to a network node. In some examples, a terminal can determine a first communication parameter associated with communication with the base station. The terminal can receive data indicating a second communication parameter via a secure network tunnel. The terminal can determine that the communication parameters do not match, and, in response, provide an indication that an attack is under way against the network terminal. Some example terminals transmit a challenge, determine a response status associated with the challenge, and determine that an attack is under way based on the response status.

INTELLIGENT DUPLICATION DETECTION FOR WIRELESS EMERGENCY ALERTS IN DEVICES
Cellular communication networks may be configured to broadcast wireless emergency alert (WEA) messages to multiple receiving communication devices. A communication device has physical-layer components, such as a modem subsystem, that receive broadcast alert messages. The modem subsystem uses a cache to record received alert messages and references the cache to perform duplication checking for newly received messages. Newly received messages that are not duplicates are provided to application-layer software for further processing. The application-layer software notifies a device user of the alert message if the alert message satisfies certain criteria. In addition, the application-layer detects changes in device properties that could potentially affect the criteria and in response causes the cache of the modem subsystem to be cleared so that the modem subsystem will not declare a subsequently received alert message to be a duplicate.
Systems and methods are described herein for handling video calls placed on hold or otherwise parked by one or more parties within the video call. The systems and methods can determine a video call has been placed on hold (or otherwise set to be parked), and transfer the video call to a call park server (CPS). The systems and methods can then access a content server, retrieve one or more content items (e.g., video clips, interactive content or advertisements, and so on), and present the content items within the on hold video call.

In a 5th-Generation (5G) cellular communication network, charging customers for data usage is performed by a network function referred to as a charging function (CHF). A session management function (SMF) of the network repeatedly sends update requests to reserve additional data for a data session. If the CHF is not available and the SMF does not receive a response to an update message, the SMF continues to assign data for the data session, even though it has not received authorization to do so from the CHF. When the CHF becomes available, the SMF sends a request to start a second data session to continue the data connection that was previously supported by the original data session. This request specifies the amount of data that was used in the original data session without being confirmed by the CHF, allowing the CHF to account for this data usage.
Systems and methods are described for monitoring performance and allocating resources to improve the performance of a wireless telecommunications network. A wireless telecommunications network may be comprised of base stations and other infrastructure equipment, which may be sourced from various suppliers. Users may generate traffic on the wireless network, and performance metrics relating to the user experience may be collected from individual base stations. The set of available metrics for a particular base station may vary according to the supplier. A machine learning model is thus trained using metrics from multiple base stations, and used to estimate values for metrics that a particular base station does not provide. The metrics are then further characterized according to the service classes of the users, and resources for improving the performance of base stations are allocated according to the reported and estimated metrics for various service classes.
An improved telecommunications network that can reduce the network load on a rich communication services (RCS) server and/or local routers that implement 1-to-N and/or M-to-N services is described herein. In particular, the improved telecommunications network may include an improved RCS server that can route multicast messages instead of and/or in addition to unicast messages. For example, the improved RCS server can create a multicast group for a group of UEs in response to a request from a UE to create a group of UEs. Creation of the multicast group may include assigning a group Internet protocol (IP) address to the multicast group. The improved RCS server can then determine which UEs in the multicast group are capable of sending and/or receiving multicast messages, and send multicast messages instead of unicast messages to these UEs.
The disclosed technology provides a system and method for scheduling downlink transmissions and for granting uplink frequency resources to a user device such that concurrent transmissions and receptions by the user device, or multiple concurrent transmissions and receptions by the user device, does not lead to deleterious intermodulation distortion or at least minimizes the extent of any such resulting intermodulation distortion.
An improved telecommunications network that can reduce the network load on a rich communication services (RCS) server and/or local routers that implement 1-to-N and/or M-to-N services is described herein. In particular, the improved telecommunications network may include an improved RCS server that can route secure multicast messages instead of and/or in addition to unicast messages. For example, the improved RCS server can create a multicast group for a group of UEs in response to a request from a UE to create a group of UEs. Creation of the multicast group may include creating a shared multicast group key (SMGK) for the multicast group and/or selecting a security algorithm for the multicast group. The improved RCS server can then distribute the SMGK and/or the selected security algorithm to the UEs such that the UEs can use the SMGK and/or the selected security algorithm to encrypt and/or decrypt messages.
Various systems, methods, and devices relate to determining a delay associated with a device; calculating a guard time based at least in part on the delay; and scheduling a wireless resource to include a downlink interval, an uplink interval, and the guard time between the downlink interval and the uplink interval. By calculating the guard time based at least in part on the delay associated with the device, spectrum efficiency can be enhanced, and latency can be reduced.
Methods, systems, and non-transitory computer readable media for intelligent steering of roaming of user equipment. More particularly, the methods include receiving, from a user equipment (UE) located in a visitor network, a registration message to register with a home network, the registration message including an identifier of the UE. The methods also include querying, by one or more processors, a steering controller using the identifier of the UE to obtain a roaming list customized for the UE. The methods also include pushing, by one or more processors, the roaming list to the UE.
Techniques for dynamically determining coverage area and data throughput in a heterogeneous network are discussed herein. In some examples, a base station can use frequency resources from a Citizens Broadband Radio Service band provided that such use does not cause harmful interference for incumbent users. For example, to avoid interfering with an incumbent device while maintaining transmission, an algorithm may be deployed to dynamically determine data throughput for the base station and connected user equipment based on interference level and traffic type. The base station can receive interference information with uplink feedback from the user equipment. Interference information can also be used to configure the base station to dynamically adjust its data coverage area, for example, by varying a transmission power. As the conditions at a base station change over time (e.g., hourly, daily, weekly, etc.), data coverage area can be reconfigured at the base station.
Architecture and techniques for identifying types of objects based upon disruption of signal strength of millimeter-wave (mmW) transmitted signals caused by objects interfering with or blocking transmitted signals within a wireless communication network. In particular, types of objects may be identified based upon drops in signal strength due to objects moving between a transmission point and a receiving device. Based on factors including one or more of a size of an object, materials that make up the object, etc., the object causes a drop in received signal strength, thereby causing a change in a pattern of received signal strength. The changed pattern may be compared with base patterns that are correlated with a type or identity of an object in order to identify the object.
A method for discovering an interface session within a wireless communication network is discussed herein. The method includes establishing an Internet Protocol (IP) packet-switched network registration between a first node of a plurality of nodes within the wireless communication network and a second node of the plurality of nodes. The method further includes, requesting, by a third node of the plurality of nodes from a fourth node of the plurality of nodes, service for a call of a mobile device within the wireless communication network. Based upon not having an appropriate interface session established between the first node and the fourth node, the method also includes performing, by the fourth node, an interface session discovery. Based at least in part on the interface session discovery, a dedicated bearer is established at the second node for the call.
Systems and methods are described herein for configuring vehicles and infrastructure (e.g., buildings, smart homes, traffic devices, utilities and associated systems, emergency response systems, and so on) to include blockchain nodes, so a smart city or area of the various devices can be supported by a blockchain network, with some or all devices and systems provisioned with nodes acting as distributed nodes for the blockchain network.
H04W 4/46 - Services specially adapted for particular environments, situations or purposes for vehicles, e.g. vehicle-to-pedestrians [V2P] for vehicle-to-vehicle communication [V2V]
Systems and methods are described herein for providing mobile devices with peer to peer access to telecommunications networks. The network-based systems enable mobile devices associated with subscribers of the telecommunications networks to establish direct connections with other mobile devices (e.g., third party mobile devices of users that are not subscribers) over peer to peer (P2P) communication protocols. For example, a mobile device can, over a P2P connection, act as a Hotspot, Wi-Fi tether, or bridge for a third party or other mobile device requesting access to the networks.
A system and method for detecting and correcting uplink-only problems is disclosed. The system comprises one or more of the following modules: uplink problem detection module, maximum permissible limit module, and uplink improvement calculation and actions module. The uplink problem detection module detects uplink-only problems using values of one or more parameters related to bearer performance. For instance, the uplink problem detection module continuously monitors the uplink performance by checking uplink transmission error and when a threshold is crossed, declares an uplink problem. The maximum permissible limit module limits the actions by uplink improvement calculation and actions module so that other parts in the system are not negatively affected. The uplink improvement calculation and actions module determines and performs the actions to improve the uplink transmission error situation detected by the uplink problem detection module.
Systems and methods are described herein for storing and/or retaining message object data for subscribers of a wireless network. The systems and methods introduce a storage architecture that retains message objects in both hot storage (or local storage) and cold storage (remote or archive storage), to comply with the OMA and/or GSMA standards. After certain events associated with the message objects occur, such as an expiration of a time-to-live (TTL) parameter for the message objects, the systems and methods purge or remove message objects from the local storage, but maintain the message objects in the remote storage location.
Systems and methods are described herein for providing a telecommunications network, such as a wireless network, LTE (Long Term Evolution) network, and so on, with blockchain nodes, agents, or sub-nodes. The blockchain nodes enable network components to access and maintain a blockchain for the network, such as a distributed ledger that tracks actions, activities, or other transaction associated with the telecommunications network.

The methods, systems, and computer readable media discussed herein are directed to enabling a fifth generation cellular-wireless access technology (5G) user equipment (UE) to receive 5G service using a fourth generation cellular-wireless access technology (4G) subscriber identity module (SIM). Upon powering on, the 5G UE may determine whether a mobile network operator (MNO) public key file exists in the 4G SIM. Upon determining that the MNO public key file exists in the 4G SIM, the 5G UE may retrieve a MNO public key value from the MNO public key file, read a subscription permanent identifier (SUPI) from the 4G SIM, generate a subscription concealed identifier (SUCI) based on the SUPI and the MNO public key value, send the SUCI to a 5G mobile network for registering the 5G UE, and begin receiving 5G services from the 5G mobile network.
The disclosed technology provides a system for scanning frequency channels that reduces the number of frequency channels scanned from among all the possible frequency channels that a wireless communication device can operate on. The wireless communication device uses historical data on last successful connection together with device data metrics from the last successful connection to determine a probability of successful connection for each of the potential frequency channels. The wireless communication device then ranks the probability associated with each frequency channel to determine a frequency scanning order that results in fewer frequencies being scanned before an appropriate channel is identified.
A 5G user equipment (UE) can register for 5G services with a telecommunication network in part using a Subscription Concealed Identifier (SUCI), an encrypted version of a subscriber identifier, so that the actual subscriber identifier is not exposed during network registration. Legacy SIMs originally deployed for 4G/LTE and other legacy wireless access technologies store an international mobile subscriber identity (IMSI), but do not store a network public key needed to generate a SUCI. However, a 5G UE can still use a legacy SIM to securely obtain 5G services by encrypting the IMSI from the legacy SIM using a network public key stored in the 5G UE's own memory to generate a SUCI, and then transmitting the generated SUCI to the telecommunication network during network registration. Accordingly, the IMSI on the legacy SIM is not exposed during network registration.
Systems and methods for enabling one-way video calling are disclosed. The system can enable user equipment (UE) with varying capabilities to communicate in an asymmetrical manner. A UE receiving an incoming two-way video call can request that the call be "downgraded" to a one-way video-in call, a one-way video-out call, or even an audio-only call. The system can include a multi-way video graphical user interface (GUI) to enable the user to choose between accepting an incoming two-way video call or requesting a different type of call (e.g., a one-way video call or an audio-only call). The system can also include a call initiation GUI to enable users to select between two-way video, one-way video, or audio-only for outbound calls. The system can also include a call modification GUI to enable users to modify the parameters for an incoming call prior to initiating the call.
Systems and methods for providing additional video call transfer functionality are disclosed. The systems and methods can enable a video call between a first user equipment (UE) and a second UE to be transferred to a video call between the second UE and a third UE either a video call or an audio call. The systems and methods can also enable the third UE to accept a transferred video call or to request that the video call be downgraded to an audio call. The systems and methods can incorporate a multimedia resource function (MRF) to connect to the second UE while the transfer is being negotiated and effected. The MRF can provide an audio stream and a video stream to the second UE to provide a "video hold" feature - to prevent the video call from dropping to an audio call automatically or dropping altogether.

LATENCY-SENSITIVE NETWORK-TRAFFIC QUALITY OF SERVICE
A telecommunication system can include routing devices, a bearer-management device, and a policy-management device. The bearer-management device can receive a request from a terminal to create a specialized bearer (SB) for a non-audio, non-video media type. The bearer-management device can determine that the request is associated with an authorized user, and then send a setup message comprising a Quality of Service (QoS) indicator to the policy-management device. The policy-management device can create the SB permitting data exchange between the terminal and a routing device. The SB can have QoS characteristics associated with the QoS indicator. In some examples, the terminal can receive a network address, determine an associated network port, and send a SIP INVITE message indicating the non-audio, non-video media type. The terminal can then exchange data on the network port with a peer network terminal.
Devices, systems, and methods relate to performing Internet Protocol (IP) Media Subsystem (IMS) bearer activation and radio bearer activation at different times. In some embodiments, a radio bearer is activated after the IMS bearer is activated. The radio bearer that is activated after the IMS bearer is activated may utilize a different Radio Access Technology (RAT) than an initial radio bearer. In certain instances, a device initiates activation of the radio bearer upon receiving confirmation that the IMS bearer is activated, or initiates activation of the radio bearer a predetermined period of time after initiating activation of the IMS bearer. In various embodiments, staggered IMS bearer activation and radio bearer activation can prevent collisions at components of an Evolved Packet Core (EPC).

BEARER SELECTION FOR DUAL CONNECTIVITY CELLULAR SYSTEMS
When using Dual Connectivity in a Non-Standalone Architecture cellular communication system, a data bearer may be steered through a Long-Term Evolution (LTE) base station or a New Radio (NR) base station. Each bearer is assigned a combination of Quality of Service (QoS) values corresponding to the service type that the bearer is supporting. For example, each different service type may be assigned a combination of a QoS Class Identifier and an Allocation and Retention Priority parameter value. Each combination is also associated with a radio access technology such as LTE radio access technology or NR radio access technology. When NR communications are available between a network core and a communication device, and if the bearer's combination of QoS values has been associated with NR, bearer data is routed through an NR base station. Otherwise, the bearer data is routed through the LTE base station.

A group database can maintain information about member user equipments (UEs) that are part of a group associated with a shared group number. One or more of the member UEs can be associated with distinct phone numbers that are different from the shared group number. One or more communication servers can route incoming calls and text messages sent to the shared group number to one or more member UEs based on the information in the group database, such as routing incoming calls only to member UEs indicated as being active members of the group in the group database.
During a call session between a first user equipment (UE) and a second UE managed by a call application server, the first UE can send a request to a conference application server to upgrade the call session to a meeting session. The conference application server can set up the meeting session. Once the first UE and the second UE have joined the meeting session with the conference application server, the first UE and the second UE can end their legs of the original call session with the call application server. The first UE and the second UE can transition their user interfaces from a call mode to a meeting mode upon joining the meeting session, such that users are seamlessly transitioned from a call to a meeting.
Techniques for dynamically allocating frequency resources in accordance with wireless access technologies are discussed herein. For example, a base station can determine whether user equipment (UE) requesting communications at the base station are configured to operate in accordance with 4th Generation (5G) radio access technologies and/or in accordance with 5th Generation (5G) radio access technologies. Based on the number of 5G UEs and 4G UEs, a first portion of a frequency resource can be allocated to 5G and a second portion of the frequency resource can be allocated to 4G. In some examples, a first allocation strategy for a first frequency resource (e.g., Band 71) can be used to generate a second allocation strategy for a partially overlapping second frequency resource (e.g., Band 41).
A telecommunication system can include a network flow controller (e.g., SMF) and a network-charging node (e.g., CHF). The flow controller can generate a first charging-event record associated with a network session. The flow controller can detect an outage at least partly by determining that no network-charging node is available to receive the first charging-event record and, in response, mark the first charging-event record to provide a first marked charging-event record. The flow controller can store the first marked charging-event record in a buffer. After the marking, the flow controller can determine that a network-charging node is available to receive the first marked charging-event record, and, in response, send the first marked charging-event record to the network-charging node. The network-charging node can determine a charging-data record indicating occurrence of an event during the outage.
A first user equipment (UE) - during a real time text (RTT) communication session with a second UE - may be configured to transmit RTT content in "word mode" by buffering text characters in local memory as they are typed by a user, and holding off on transmitting the buffered text characters until the user types a word delimiter or a timer expires, whichever occurs first. In an example process, the first UE may detect character user input requesting to type a text character, and, in response, the first UE starts a timer and buffers the text character in local memory. The timer can be restarted for additional text characters that are typed before expiration of the timer, and those additional text characters are also buffered. The buffered text characters are transmitted upon detecting delimiter user input requesting to type a word delimiter or the expiration of the timer, whichever occurs first.
Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include determining a location of a device; selecting, based at least in part on the location of the device, a mini-slot size; scheduling, in one or more mini-slots having the mini-slot size in a PRB, a HARQ transmission; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

CONTROLLING FALLBACK PROCEDURES FOR DIFFERENT USER GROUPS OR DEVICE GROUPS
A user equipment (UE) and an Internet Protocol (IP) Multimedia Subsystem (IMS) node may exchange fallback indicators in SIP signaling for purposes of controlling fallback procedures implemented by the UE. The SIP signaling may include a SIP request from the UE that includes first information. The IMS node can evaluate a criterion based on the first information, and, if the criterion is met, the IMS node may authorize (or prohibit) the use of a UE-supported fallback radio access technology (RAT) that corresponds to a fallback indicator also included in the SIP request. Based on the evaluation of the criterion, the IMS node may respond to the UE with a SIP response that includes second information indicating which of the supported Fallback RATs the UE is authorized to use (if any), and which of the supported Fallback RATs the UE is not authorized to use (if any).
A network base station can select, for each of one or more attached terminals, a respective downlink transmission mode (DTM) based at least in part on respective channel condition information (CCI). The base station can determine a subframe allocation of DTMs to subframes of a radio frame, and transmit downlink data to terminals based the subframe allocation. Additionally or alternatively, the base station can receive load information from a second base station associated with a different access network and determine the subframe allocation based on the load information. The subframe allocation can associate a specific access network with each subframe. Additionally or alternatively, the base station can send the subframe allocation to the second base station. Additionally or alternatively, the base station can determine a proportion of GBR traffic of a particular DTM, determine a reference-signal transmission rate associated with that DTM, and transmit reference signals accordingly.
Systems, devices, and techniques described herein relate to migrating a communication session from a path including a stressed user plane function (UPF) to a path including a replacement UPF. A communication session may traverse a first path including the first UPF. After establishing the communication session, the first UPF may be determined to be stressed. In response, the communication session can be proactively migrated to a second path including a second UPF. According to various implementations, the existing communication session can be maintained during the migration, thereby substantially eliminating interruptions caused by the stressed first UPF.
A cellular communication device is configured to use Non-Standalone Architecture (NSA) dual connectivity for communicating with a cellular communication network, using simultaneous 4th-Generation (4G) Long-Term Evolution (LTE) and 5th-Generation (5G) New Radio (NR) radio access technologies. When implementing NSA dual connectivity, the device may receive separate transmit power control commands for LTE uplink transmissions and NR uplink transmissions, respectively. In order to keep total transmitted power of the device below a regulatory maximum transmit power, LTE transmit power is limited to a value that is less than regulatory maximum transmit power, thereby reserving at least a reserved transmit power for NR transmissions. This allows NR acknowledgements to be sent from the device to avoid NR downlink failure.

CACHE AND MULTICAST TECHNIQUES TO REDUCE BANDWIDTH UTILIZATION
Techniques are described herein for caching content locally at a local network device and serving the cached content via multicast transmission to a user equipment in a multicast single frequency network (SFN) coverage area in which the local network device is located. The local network device receives a request for content from the user equipment in the multicast SFN coverage area. The request includes usage data associated with the user equipment indicating a triggering event. If the content is not cached at the local network device, the local network device identifies a content server to provide the content based at least on the usage data and a broadcast identifier associated with the local network device. The local network device receives the content that is associated with the broadcast identifier of the local network device and stores the content locally, which is then served via multicast transmission to the user equipment.

ZERO CODING AUTOMATION WITH NATURAL LANGUAGE PROCESSING, SUCH AS FOR USE IN TESTING TELECOMMUNICATIONS SOFTWARE AND RESOURCES
A framework for automated testing for use in testing telecommunications software and resources is disclosed that reuses testing code modules, thereby reducing redundancy and increasing efficiency and productivity. The zero coding automation system disclosed herein provides an end-to-end testing automation framework, which minimizes (and in some cases eliminates) the requirement for testers to write software code to test software modules. Instead, the coding automation systems and methods provide a hierarchical framework to translate testing requests (commands, statements, and so on) received in a natural language (for example, English) to testing code modules written in, for example, one or more programming languages (for example, tool specific Application Program Interface (API)/libraries developed to test functionality).
Systems and methods discussed herein are directed to allocating subframes (or slots) of radio frames for LTE uplink transmissions and NR uplink transmissions. In some instances, subframes (or slots) of radio frames may be allocated for LTE downlink transmissions and NR downlink transmissions.
Techniques are described herein for implementing a presence application server to handle Universal Profile (UP) transfers over roaming. The presence application server may receive a Session Initiation Protocol (SIP) request from a user device. The SIP request can include presence information of the user device, P-Access-Network-Info (PANI), and a subscriber identifier of a subscriber associated with the user device. Based at least on the presence information, the presence application server can determine whether the user device is UP capable. Additionally, the presence application server can determine whether the user device is roaming based at least on the PANI. If the user device is roaming, the presence application server can indicate that the user device is roaming and remove a tuple associated with the presence information indicating the UP capabilities of the user device in a SIP response. Removing the tuple suspends the user device's UP capabilities.

MOBILE AERIAL DRONE EARLY WARNING PRIVACY BREACH DETECT, INTERCEPT, AND DEFEND SYSTEMS AND METHODS
Systems and methods for aerial unmanned vehicle (for example, drone) early warning privacy breach detection, interception, and defense are disclosed. The system detects drones within a threshold distance of an individual or configurable location, notifies the individual of the drones' existence, tracks the drones, and executes countermeasures. The system can communicate with telecommunication networks or other sources (for example, FAA) to identify and filter out drones that are authorized to be in the airspace around the individual.
A fifth generation (5G) radio access network (RAN) can determine that a user equipment (UE) should fall back to engaging in a communication session over an LTE-based Evolved Packet System (EPS) instead of a 5G system. However, to avoid interrupting setup operations that may be occurring separately for that communication session in an IP Multimedia Subsystem (IMS) apart from the 5G system, the EPS fallback can be delayed such that setup in the IMS can proceed at least to a point at which IMS signaling messages are less likely to be undeliverable due to the EPS fallback.
Systems, devices, and techniques described herein relate to intelligently allocating network resources to Quality of Service (QoS)-sensitive data traffic. An example method includes identifying a request to deliver QoS-sensitive services to a User Equipment (UE) over at least one delivery network. The at least one delivery network may include at least one reserved resource and at least one pooled resource. The QoS-sensitive services are determined to be delivered over the at least one pooled resource. In addition, delivery of the QoS-sensitive services is caused over the at least one pooled resource.
Systems, devices, and techniques described herein relate to user plane system selection based on latency in mobile networks. In particular, the systems, devices, and techniques can be implemented in fifth generation (5G) mobile networks to provide selection of a user plane function (UPF) based on latency. The UPF can measure a latency toward an access network and provide an indication of the latency to a policy control function (PCF). The PCF can select the UPF based on the indication and can request the UPF to provide services to a user equipment (UE) originating a priority request. In response, the UPF can provide services to the UE.
Policy based dual connectivity traffic steering is described herein. A master Long-Term Evolution (LTE) base station may operate in conjunction with a secondary New Radio (NR) base station to provide dual connectivity to user equipment (UE) operating in an environment. The LTE base station can steer traffic between the LTE base station and the NR base station based at least in part on policy information received at the LTE base station. The policy information can indicate, for a particular UE and for a particular Quality of Service (QoS) Class Identifier (QCI), whether the LTE base station can transfer a communication to the NR base station. Thus, traffic steering determinations can be based on the policy information, quality identifiers, device capability, signal strength(s), load level(s), and the like, thereby providing a flexible framework for steering wireless traffic in a dual connectivity environment.

SYSTEMS AND METHODS FOR MANAGING CELLULAR MULTI-CONNECTIVITY
Systems and methods for managing multiple network connections for user equipment (UE) are disclosed. The systems and methods can monitor power headroom (PHR) reports on one or more networks. When the PHR report for a UE approaches a first predetermined level on a first network, the system can evaluate the UE for a predetermined amount of time. If during the predetermined amount of time, the PHR on the first network increases to a second predetermined level - i.e., to a level where the transmission power used by the UE is closer to a maximum transmission power that the UE can provide - the UE can be instructed to disconnect from the network. This can enable the UE to disconnect in a controlled manner rather than simply letting the connection "drop" due to radio link failure.

TIME-DIVISION MULTIPLEXING FOR 5G NETWORK COVERAGE EXTENSION
Techniques for time-division multiplexing for extending 5thGeneration (5G) network coverage are described herein. In an example, a device operating in a dual transmission mode for transmitting data via a first network node associated with a 5G network and a second network node associated with a 4th Generation (4G) network at or near a same time, can determine a measurement associated with a transmission and/or receiving characteristic. The device can determine that the measurement meets or exceeds a threshold and, based at least in part on determining that the measurement meets or exceeds the threshold, the device can transition to an alternating transmission mode for transmitting data via the first network node and the second network node in an alternating pattern thereby extending 5G network coverage.

USE-TRIGGERED SIGNAL SCANNING FOR NETWORK DETECTION
A wireless communication system may support two types of networks, such as a 4th- Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. During idle mode, a communication device may scan 5G RF frequencies to determine whether a 5G signal is available and whether to display a 5G network symbol in the status bar of the device. The communication device is configured to detect conditions indicating whether a user of the device is likely viewing the device and/or the display of the device. If it is unlikely that the user is viewing the device or its screen, RF frequency scanning is paused to reduce power consumption and the currently displayed network symbol is maintained until RF frequency scanning is resumed.
