    Abstract: A mobile telephone network operating general packet radio service includes a base station (2) and a group of mobile telephones (M1 to M4). The base station (2) includes a control unit (8) which generates a succession of data packets which are transmitted along a common downlink to all the mobiles (M1 to M8). Each data packet includes a header section containing an uplink state flag (USF1) identifying a first selected mobile, to poll that mobile and cause it to return a packet of data to the base station along a common uplink channel. The header also includes an uplink state flag (USF2) identifying a second selected mobile and is accompanied by the identity of and time slot for a second auxiliary uplink channel for polling the second mobile to cause the second mobile to return a packet of data to the base station along said auxiliary uplink channel thereby enabling the polling of at least two mobiles using the same data packet. The polling sequence produced by the control unit (8) ensures that each mobile is polled twice during each polling cycle, once accompanied with the identity of and time slot for a secondary auxiliary uplink channel and once without.

    Abstract: In an Enhanced Data rate for GSM Evolution (EDGE) type packet cellular network a transmitter (10, 14, 16) and a receiver (20, 22, 12) are arranged to operate in for example eight different modulation and encoding schemes. The transmitter and receiver are connected by a communication channel (24). In the receiver there are two counters (30, 32) and a comparator (34) arranged so that the counters count the number N e and N s of received consecutive erroneous and successful packets, and the number is compared with respective stored numbers, and when one of the stored numbers is equalled, a signal is supplied through the control channel (24) so that the transmitter and receiver switch to a more or a less robust modulation and encoding scheme as appropriate.

    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: There is disclosed a transmitter including a data encoder for encoding data packets in fixed length EDGE blocks. Each data packet includes a data header and a data payload. The transmitter additionally includes a speech encoder for encoding speech packets each including a speech header and a payload comprising a speech frame. The speech packets are encoded into blocks of equal length to the EDGE data blocks, the speech header being reduced relative to the data header.

    Abstract: A cellular radio communication system is disclosed for effecting handover of radio transmissions between a mobile station and one cell of a multicell network from said one cell to another cell of the network. The mobile station has a plurality of modes of operation in conjunction with the network. The plurality of modes includes a) a mobile station controlled autonomous cell reselection mode with no measurements being reported to the network, b) a mobile station controlled autonomous cell reselection mode with a measurement report being transmitted to the network, c) a network controlled cell reselection mode with a measurement report from the mobile station to the network, and d) a network controlled real time cell selection mode with a measurement report from the mobile station to the network.
