A temporary label value is stored in a selected control data storage location to render the selected location and a corresponding key data storage location inactive for read-out. The write-availability of the control data storage location is changed to the second write-availability state in association with the storage of the processed label value in the selected location. A read-out label value is obtained and the temporary label value stored in the selected control data storage location is over-written with the obtained read-out label value, to render the selected control data storage location and corresponding key data storage location active for read-out.

In operation, packets traverse the packet processing data structure, and the network processing represented by each object in the data structure is applied to each packet. From time to time, the packet processing data structure may need to be updated. Embodiments of the present disclosure provide for lock-free updating of a packet processing data structure by means of epoch-based garbage collection. In embodiments, a particular past packet processing epoch is considered to be no longer referenced by any cores when the sequence numbers recorded in each said memory location are different to the sequence number of that particular past packet processing epoch. The deletion thread checks both whether a past epoch is being referenced by any packets and whether it is being reference by any cores. Thus memory is safely freed without having any impact on any packet processing which may be occurring in parallel to the deletion thread.

A network, configured to perform network slicing, receives information from a Session Management Function, SMF, relating to a 10 given packet data session belonging to a given network slice. Based on the information received from the SMF, the network signals to a UPF instance that the given packet data session belongs to the given network slice.

The techniques disclosed herein enable systems to perform ordered reconvergence operations following a change to a topology of a communications network. To perform ordered reconvergence, a system detects a change to network topology such as a link failure or node addition. In response, the system determines a global delay based on a maximum distance between two nodes within the network, a local delay for each node within the network, and an ordered delay for each node based on the global delay and the local delay. Upon detecting that the ordered delay for a node has elapsed, the system can then update a routing table for the node. After updating routing tables for every node, the system can route data in the changed network topology using the updated routing tables.

Measures, including methods, systems and non-transitory computer-readable storage mediums, for use in providing presence notifications on behalf of an endpoint that does not participate in presence notification are disclosed. In embodiments, the presence server receives notifications from a switch providing services to the non-participating endpoint relating to that endpoint's status from which presence can be determined. This information is processed using a dummy roster in order to send out notifications. The dummy roster may be created responsive to receiving a subscription to presence notifications for the non-participating endpoint.
Embodiments of the present invention provide methods for providing a non-registering endpoint with non-registration services (such as the ability to make a call) in an IMS network without requiring the non-registering endpoint to register. A request for a non-registration service is received and processed by an entity in the IMS network that is configured to handle such requests. The entity requires information about the non-registering endpoint itself before it can process the request. Since the non-registering endpoint is part of the network, a Home Subscriber Server (HSS) knows some information about the non-registering endpoint, but can only provide this information to the entity if the non-registering endpoint is registered or being registered by the entity. Consequently, in embodiments, the entity makes it look like the non-registering endpoint is registering, in order for the entity to obtain the information from the HSS.
Measures, including methods, systems and computer-readable storage mediums, for use in processing notifications relating to telecommunication sessions. A cluster of servers is operable to receive incoming notifications where each server can process any given notification and update a store holding records based on previous notifications. The cluster may include a timer function to allow records to be closed when no relevant notifications are received after a timeout interval.
Measures for use in operating a subscriber device in a network. An audio call communication session is conducted between the subscriber device and an audio call client of a remote user device. The audio call communication session includes the transfer of audio data between the subscriber device and the audio call client of the remote user device. During the audio call communication session, transmittal, to a user interface associated with a user of the remote user device, of information associated with switching communication from the audio call client of the remote user device to a web browser client is caused. A real-time media data communication session is established between the subscriber device and the web browser client. Real-time media data is transferred between the subscriber device and the web browser client instead of audio data between the subscriber device and the audio call client of the remote user device.

Measures for use in operating a network node in a telecommunications network. At a network node located in a second part of the network, signaling messages transmitted between a server and end devices in an at least a first group are monitored. Each monitored signaling message includes a telephone dialing number for a given end device in the at least first group and an extension number for the given end device. On the basis of the monitoring, mapping data is stored which includes mappings between telephone dialing numbers and extension numbers for end devices in the at least first group. In response to detecting a loss of connectivity between a first part of the telecommunications network and the second part of the telecommunications network, extension number dialing request messages received from end devices in the first group are processed according to a detected loss of connectivity operating mode.
Multiple session initiation protocol (SIP) devices connected to a server via a network may attempt to initiate a process (such as SIP registration) at approximately the same time as each other, by sending SIP messages (e.g. “REGISTER” messages) towards the server substantially simultaneously. Depending on the number of devices and the resources of the server, the server may not be able to process all of the messages without crashing. An interposed network element, such as a session border controller (SBC), may prevent some of the messages from reaching the server, to stop the server from crashing. However, some messages may be of higher priority than others. The invention provides a way of differentiating between messages to assist in prioritising messages with higher priority over others.
A message is processed at a node in a cluster of nodes. The message is received at the node. The message is addressed to at least one other node in the cluster. At least one action associated with the message is performed at the node. A response message is transmitted indicating that the at least one action has been performed.
The invention relates to sending media packets, such as SIP or RTP, via a media forwarding element which includes an anycast interface having an address shared with other media forwarding elements. If network topology changes or a media forwarding element becomes unavailable, then anycast messages may be routed to a different media forwarding element sharing the same anycast address. The new media element can then take over handling of the call from the first one.
