Abstract: A system (Fig. 4) and method (50) which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need t o purge data by transmitting a purge command (54), which prompts the Node B to delete at least a portion of buffered data. The purge command (54) can inclu de instructions for the Node B to purge all data for a particular UE, data in o ne or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.

Abstract: Techniques for use in a wireless device are provided. The techniques include monitoring a status of an amount of data in at least one buffer for transmission; determining an indication of additional capacity for transmission; transmitting at least one signal with an indication based on the monitored buffer status and the indication of additional capacity for transmission; and transmitting data of the at least one buffer based on the transmitted at least one signal.

Abstract: A Radio Local Area Network (RLAN) includes a Radio Access Network Internet Protocol (RAN IP) gateway that enables connectivity to the public Internet. The system may serve as a stand-alone system or be incorporated into a UMTS used with conventional Core Network, particularly for tracking and implementing AAA functions in the Core Network.

Abstract: The present invention relates to efficient recovery of High Speed Downlink Packet Access (HSDPA) data following handover. The present invention disclos es a method and system for the UE to perform a serial of actions in order to reduce the latency and potentially prevent loss of PDU transmission during the serving HS-DSCH cell change procedure. A new criterion is introduced for UE generati on of the status report of RLC PDU. The UE generates status report of the PDUs as soon as possible following notification of the HS-DSCH cell change indicated by the RRC procedure to more efficiently recover source Node B buffered data. P DU status may be signaled for each AM RLC instance associated with the HS-DSCH transport channel. Furthermore, upon Inter Node B serving HS-DSCH cell change the SRNC may wait for PDU status report before initiating transmissio n of new data in target cell.

Abstract: A medium access control (MAC) architecture reduces transmission latency for data block retransmissions. A plurality of data blocks are received and temporarily stored in a first memory (815B) (e.g., queue, buffer). The pluralities of data blocks are then transmitted. A determination is made as to whether each of the transmitted data blocks was received successfully or needs to be retransmitted because the data block was not received successfully. Each of the transmitted data blocks that need to be retransmitted is marked and temporarily stored in a second memory (815A) having a higher priority than the first memory (815B). The marked data blocks are retransmitted before data blocks stored in the first memory (815B) location.
