A single soft-bit value (r) for each binary value based on the hard-bit values (b1, b2, S 1 -S 6 ) of the relevant binary value is generated and the bit value of the binary value is determined by subjecting the soft-bit values (r) to a soft-decision algorithm.

A method for improving distributed resource allocation in OFDMA based wireless communication networks such as WiMAX IEEE 802.16 for either fixed or mobile subscriber stations SSs (90', 91') is executed by neighbour Base Stations BSs (100', 101') serving the SSs. Each BS controls the allocation of respective permutation zones and radio resources encompassing different radio subchannels within each permutation zone. In this task the BS avails of RRM primitives and instances of a NCMS functionality promoting direct BS-to-BS communication, which can be exploited in a distributed RRM profile. A BS playing the role of RRC sends to Neighbour BSs a unique RRM Request (102') for receiving event-driven Spare Capacity Reports. Among driving events, 'Change of Radio Resources Allocation' is included. Neighbour BSs, at every allocation change is detected, send to the requester BS a Spare Capacity Report (104') including a Bitmap indicating subchannels used for transmission in each Permutation Zone. In order to eliminate Co-Channel Interference CCI, the requester BS avoids using same subchannels already indicated in the received Bitmap.

Error recovery procedures in TCP/IP transmissions over radio channels (100) of wireless communication systems such as 3G LTE systems are optimised by suppressing transmission of standalone uplink TCP acknowledgment (TCP ACK) packets. Upon reception of a data packet at a base station (21 ) and a user equipment (10) involved in a transmission, the respective TCP ACK packet is generated along with a representation much shorter than the whole of the TCP ACK packet and the overhead added at the network, link and physical layers. The representation is calculated by applying the same hash function to the packet header. The representation calculated at the base station (21 ) is stored into a hash table (27) with the corresponding TCP ACK. The representation calculated at the user equipment (10) is transmitted back to the base station in place of the TCP ACK packet and serves as a reading address for retrieving the corresponding base station TCP ACK from the hash table (27) and releasing it to a data source (80).

A method of fitting a message response to a frame size comprises preparing a query message to send from a user device to a network; allocating priority levels to each information element in the message and providing the information elements and their allocated priority levels in the message. The message is sent to the network; and at the network, a maximum permitted frame size for a response is determined and the response is prepared. The size of the response is compared with the maximum frame size. If the size of the response exceeds the maximum frame size, the number of information elements in the response is reduced by removing information elements having lowest priority until the response is within the maximum permitted frame size; and the filtered response is sent.

The method establishes connections from and to a secondary client (SIP-client) of a packet-switched network (SIP network) to and from a circuit-switched wireless telephony net work. The secondary client (SIP-client) of the packet- switched network is identified by the same MSISDN number as a first, mobile client being subscribed to the circuit-switched wireless telephony network. In case of the secondary client calling, a IN (Intelligent Net) service (SIP-S) is used which provides the GSM services normally being executed by a VMSC (Visited MSC) for a roaming mobile phone. In case of a MSISDN number shared between a first, mobile client and a secondary SIP-client being called, after execution of all terminating GSM services, an IN (Intelligent Network) Service (SIP-S) is used to let both clients ring in parallel, and establish connection to that client which answers first.

A method is disclosed of adaptively de-jittering packetized signals buffered at the receiver of a communication network node. The method is executed by a Jitter Buffer Manager (JBM) to optimize the end-to-end delay for call quality of Voice-over-IP communication. According to the method, the JBM stores the packets in the buffer and determines an appropriate adjustment time for packet dequeuing based at least in part on a result of voice activity detection performed on the received data stream. A target maximum buffer length is set and, comparatively, an initial filling level as the number of packets to be stored in the buffer at the beginning of the packet stream reception before delivering the first packet. Overrun and underrun thresholds are set in respect of the current filling level of the buffer. Exceeding the overrun threshold or going below the underrun threshold increments a respective event-counting. Two alarm thresholds are set by a permitted value of the difference between overrun and underrun counting, and vice versa. Exceeding the alarm thresholds is monitored to trigger either discarding stored packets or storing void packets in the buffer starting from a boundary of a zone filled up with packet marked as silence. After each event of discard or insert packets the relevant event-counting is reset.
