Abstract: A mobile station operating in EGPRS mode needs to the early establishment of an uplink TBF although has not data to send, at the only precautionary purpose of preventing an intolerable latency negatively affecting the subsequent delay-sensitive transmissions. To this aim, the mobile sends a Packet Channel Request message in one phase access mode including a new establishment cause called “Early TBF establishment.” The network establishes an uplink TBF indicating the requester and assigns a radio resource on one PDCH channel or more. Then the network schedules the transmission from the mobile station also when it does not have data to transmit other than dummy packets. This is performed through the USF flags in the usual manner. As soon as actual data become available for transmission, the mobile send them instead of dummy packets. In an alternative embodiment the mobile sends the Packet Channel Request message in two phase access mode.

Abstract: When a new connection needs to be established in a mobile radio network between the core network and the radio access network to terminate a local circuit switched (CS) call, i.e. a CS call for which another connection has already been established between the core network and the same radio access network, the core network includes an optional information element containing “Other party information” in the messages that establish the new connection, allowing the radio access network to correlate the two connections, put them in direct communication and exclude the core network from the user plane data flow.

Abstract: A method of allocating uplink radio resources to a mobile device, in which uplink and downlink timeslots are allocated, and the sum of the allocated uplink timeslots and the allocated downlink timeslots within a predetermined period is less than the total number of assigned time slots and does not exceed a predetermined maximum. The resources are allocated in a reduced transmission time interval configuration, in which an indication of the uplink timeslot allocation is received from the network in a downlink timeslot, or downlink timeslot pair, directing the mobile device to transmit only in one uplink timeslot pair.

Abstract: An application encoder generates independently accessible symbols and these symbols are aggregated by symbol aggregation means into a packet payload. The aggregated symbols in the packet payload are transported in a defined packet structure. These packets are transported over a channel by a packet transmitter that segments the packets into different segments by segmentation means. A segment receiver included in a first entity has the ability to detect whether a certain segment is lost and also knows the length of the lost segment. The segments are aggregated in the first entity to form at least one packet conforming to the packet stream. A symbol parser entity recovers the symbols and passes the individual symbols to an application decoder. The symbol parser in the second entity recovers, from the recovered non-lost information of each received packet, individual symbols.

Abstract: A fast ARQ mechanism operated inside 3GPP GERAN mobile radio systems uses short bitmaps, spanning only few octets, in the header of a RLC/MAC block conveying relevant ACK/NACK signalling that is transmitted either in the uplink or downlink direction, indifferently. This short bitmap which may request synchronization between transmitting and receiving frames, is encoded together with the header using coding which is more robust than that used for payload. Correct retransmission of badly received radio blocks is based on the number of RLC/MAC block periods between the instant of transmission of a radio block and the instant of reception of the short bitmap. In addition, the short bitmap is allocated in a new zone placed immediately after the header of the RLC/MAC blocks, and encoded independently of the payload using a more robust coding against the errors than the robustness of the MCS used in the payload data part.

Abstract: A transmitting peer transmits radio blocks over a radio interface from within a transmit window. A receiving peer receives the radio blocks within a receive window, and in case of a not correctly received radio block, sending back a NACK (Not Acknowledged) signaling message to inform the transmitting peer of reception failure. Upon reception of the NACK signaling message, the transmitting peer retransmits, until expiration of the transmit window, the not correctly received RLC/MAC radio block. The radio blocks are re-assembling in sequence at the receiving peer. Each radio block is considered as being permanently lost if not correctly received within the receive window. All correctly received radio blocks are delivered to a higher protocol layer. The network transmits a notification message to both the transmitting peer and the receiving peer to select a size of the transmit and receive windows inside a range of predetermined values including values less than 64 radio blocks.
