Abstract: The present invention provides a method for implementation in user equipment that is configured to communicate with a wireless communication system that includes macro-cells femtocells. The method includes determining a distance between the user equipment and the femtocell(s).

The request is generated by a radio network controller based on the periodically transmitted measurement reports.

Abstract: There is disclosed in a packet switched network a method of encoding at least two packets into a single block. Each packet is associated with a header portion. The at least two packets are associated with the same user. The method comprises encoding the at least two packets and only one of the associated header portions. An EDGE network utilizing such a method is also disclosed.

Abstract: A system for providing statistical multiplexing of speech, other real-time data services and non-real-time data services for point to point and point to multipoint communications. The system has fast access and assignment procedures that allow the multiplexing of real-time, delay-critical data services with non-real-time data services. Continuity of periodic control channels across speech talkspurt and silence periods for conversational voice is maintained to carry signal measurement reports, channel quality feedback, and “comfort” noise information between different parts of the system.

Abstract: In the GPRS, a method of decoding uplink status having reduced interleaving depth in a RLC/MAC block is proposed; for RT-EGPRS users, all of the uplink flag bits are provided in the first burst of the four bursts; and for EGPRS users, nine bits of the uplink status flags are provided in the first burst of the RLC/MAC block and the remaining bits in the next three bursts. On receiving the first nine bits, a mobile performs an autocorrelation to identify the USF whether it belongs to the EGPRS or to the RT-EGPRS group.

Abstract: A mobile terminal for communicating with a base station in a packet radio services network. The terminal has a processor for determining one of a plurality of channels for communication between the mobile terminal and the base station; for digitally coding speech to provide speech information; for assembling speech information into speech packets; and for generating channel allocation requests for a channel in which to send speech packets. A radio transmitter is provided for transmitting the requests and the packets to a base station in the network. A radio receiver receives identities of channels allocated by the base station for the mobile terminal to transmit on. The processor is responsive to each received channel allocation to determine that packets are sent on the allocated channel. In the GPRS since a channel is released when there is no packet to transmit, higher traffic levels can be obtained using the same number of radio channels.

Abstract: An SIP/SDP compression method, transmitter (510) and receiver (550) for communicating a message from the transmitter to the receiver by, at the transmitter, removing from the message element (s) thereof and inserting into the message an indication (200) of absence of the removed element (s); and, at the receiver, inserting into a message received from the transmitter element (s) pre-cached at the receiver in replacement for the element (s) whose absence is indicated. This provides a lightweight SIP/SPD compression scheme (LSSCS) that (i) removes the information redundancy generated at the application layer, and (ii) can achieve 100% compression efficiency for the redundant SIP and SDP URL fields.

Abstract: The system includes a network having a base controller (30) and a mobile station (32). The base controller (30) has a packet measurement order unit (34) which causes a package measurement reporter (68) in the mobile station to provide a measurement report. This report is stored in a buffer (44) and compared with reference values on a reference unit (48). If a change of cell is warranted, a packet cell change order unit (50) issues a command which is recorded by packet cell change unit (58) of the mobile station to retune the transmitter and receiver (54 and 56) to a new cell. The mobile station also has a unit (64) which generates a package cell change request to the base controller (30) to initiate a package cell change order from the unit (50) when a change is warranted.

Abstract: There is disclosed a technique for link adaptation, suitable for a packet switched mobile communication system, in which a command or request to change the mode of a codec in a transmitter is sent only responsive to a desired change in such mode.
