A Mobile Station, MS (115), for a cellular communications network (100), arranged to be camped on one of a plurality of k available Common Control Channels, CCCHs, in a cell (105) in the cellular communications network (100), the MS (115) also being arranged to make successive attempts at uplink CCCH access until the MS (115) gains CCCH access. The MS (115) is arranged to make CCCH access attempt number i on CCCH number x, where x is in the range of 1 . . . k, with x determined by a function in the MS (115). Also, a network node, (110), for a cellular communications network, arranged to transmit System Information messages, to the MSs (115) in a cell, and arranged to insert an Information Element, an IE, in an SI message, which IE defines which CCCHs in the cell that an MS (115) may use for uplink CCCH access attempts.

摘要:
Pre-existing methods of accessing a radio system via a random access channel as described in 3GPP TS 44.018 “Radio Resource Control (RRC) protocol” is modified to include a first additional parameter (i), which defines the spreading of the probability density function for each successive access attempt. In accordance with one embodiment the accessing user/device is configured to use a random wait time for the j-th retry to access the RACH as a function of the additional parameter (i) and the number j, where j is a positive integer.
摘要:
A signaling procedure for establishing and terminating connections for small data transmissions (SDTs) by wireless devices. A wireless device sends an access request message to a serving wireless access node on a random access channel (RACH). The access request message includes an indication that the access is for a SDT. The access request message includes the amount of data that will be transmitted as part of the SDT. The wireless access node sends an assignment message to immediately assign radio resources to the wireless device without further signaling needed for the SDT to begin. When the wireless device begins the SDT, the first data block is coded and transmitted according to a first predetermined coding scheme. If there are any subsequent data blocks, the wireless device includes an information element in the header of the first data block to indicate the coding scheme for the subsequent data blocks.
摘要:
The invention relates to a method in a mobile network for resolving a Temporary Block Flow, a TBF, in a wireless network including one or more mobile stations exchanging data with a base station system. The packet data is transmitted by means of one or more RLC/MAC blocks each associated with the TBF. The TBF is identified by means of an Temporary Flow Identity, a TFI, and associated to an MS. The inventive method is applicable in a wireless communication system with an extended TFI addressing space. The method comprises steps of receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded. When the first TFI matches assigned TFI value and is identified as a code point to an eTFI, at least a predetermined field of the RLC data block is decoded and an extended TFI, eTFI, is retrieved. The eTFI is compared with an assigned eTFI. Following a match, the payload of the RLC data block is decoded. The procedure is repeated for further RLC/MAC block associated with the TBF until the TBF is resolved.The invention also relates to a mobile station and a base station system used to resolve a TBF according to the inventive method.

摘要:
By allowing the option of placing an Logical Link Control (LLC)-entity within the Base Station Subsystem (BSS) an improved system performance in the form of mobile stations experiencing reduced information acquisition times can be achieved by using a cache memory in the BSS. A method in the BSS can include receiving one or more LLC Packet Data Units (PDUs) from a mobile station, and extracting Sub Network (SN)-PDU(s) contained in each LLC PDU and reassembling the SN-PDU(s) to recover a single N-PDU. The N-PDU is determined to include a request for information using an LLC entity in the base station subsystem. Content of a cache memory in the base station subsystem is determined to correspond to the request for information indicated by the N-PDU. A response to the request for information from the mobile station is made using the content of cache memory in the base station subsystem.

摘要:
A base station detects the transition of a mobile station from a DTX mode to a continuous transmission mode. The base station schedules an uplink transmission by the mobile station during an uplink transmission period while the mobile station is in DTX mode and receives an uplink LLC PDU from said mobile station during the scheduled uplink transmission periods. The base station determines the operating mode of the mobile station based on the size of the received uplink LLC PDU.
摘要:
A mobile station operating in extended uplink TBF mode detects renewed data activity. Upon receiving an allocation of an uplink transmission opportunity, the mobile station determines whether a data block corresponding to the renewed data activity is ready for transmission. If the data block is not ready for transmission, a dummy block, comprising an indication that one or more uplink data packets are pending, is sent to the base station at the allocated transmission opportunity. The base station responds by resuming continuous mode scheduling of the uplink for the mobile station.
