Abstract:
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.
Abstract:
System information transmitted from a wireless network is enhanced to contain additional information that indicates the relative priority between neighboring cells or frequencies in multiple Radio-Access Technologies, such as GERAN, UTRAN and E-UTRAN. In an example method implemented in a mobile station, a system information message of a first type transmitted by a base station is read. The mobile station determine whether one or more RAT priority bits are present in the system information message, wherein the presence or absence of the one or more RAT priority bits indicates whether additional ones of a plurality of available system information messages of the first type must be read before inter-RAT cell reselection may begin. If RAT priority bits are present, the mobile station selectively initiates inter-RAT cell reselection based on the one or more RAT priority bits.

Abstract:
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.
Abstract:
A method for obtaining a report from a mobile station on the status of frames comprising an entire message transmitted to the mobile station is disclosed. First, a polling request is sent to the mobile station from a base station. A status report is then sent to the base station. The polling request specifies whether the mobile station should send the status report on a reservation basis (using a reserved frame) or on a contention basis (using an idle frame). The mobile station then transmits a bit map to the communication system to indicate which frames have been correctly received by the mobile station at the point when it received the polling request.
