Abstract:
1. A method for resolving a Temporary Block Flow (TBF) in a wireless network including one or more mobile stations exchanging data with a base station subsystem (BSS) using one or more RLC/MAC (Radio Link Control/Medium Access Control) blocks each associated with the TBF and wherein the TBF is associated to a mobile station and identified by means of a Temporary Flow Identity (TFI), the method comprising: receiving a RLC/MAC block including an RLC/MAC header and an RLC data block; retrieving a first TFI from a first group of TFIs in the RLC/MAC header; comparing the first TFI with an assigned TFI; determining capability in the mobile station to retrieve an extended TFI (eTFI) field in a transmitted downlink RLC/MAC block; decoding a payload of the RLC/MAC block when the first TFI matches the assigned TFI and represents a comprehensive TFI for the associated mobile station; decoding at least a predetermined field of the RLC data block and retrieving the extended TFI (eTFI) from a second group of TFIs when the first TFI matches the assigned TFI and is identified as a code point to an eTFI; comparing the eTFI with an assigned eTFI; decoding the payload of the RLC data block when the eTFI matches the assigned eTFI; disregarding the RLC/MAC block if the first TFI does not match the assigned TFI or the eTFI does not match the assigned eTFI; receiving a new RLC/MAC block and repeating the steps for said new RLC/MAC block.
