Abstract

See full text

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.
