Method to speed up uplink data setup for GPRS mobile internet access .

摘要

To address the need for a communication infrastructure and method to speed uplink data setup, the present invention provides for the assignment of uplink packet data resources by basestation transceiver systems (BTSs) (106) without the need to communicate with any packet control unit (PCUs) (110) first. The present invention accomplishes this by reserving packet data resources before they are needed or requested and providing them to BTSs (106) for assignment. Thus, BTS-PCU communication occurs in the period before an uplink connection is needed and after uplink data is established, effectively eliminating the BTS-PCU delay from uplink data setup. Moreover, the present invention provides for the transmission of transmit allowance messages before an uplink request is made by the communication unit (102), further reducing uplink data setup time.
