Embodiment Construction

[0010] Addressing the need for a communication infrastructure and method that speeds uplink data setup, the present invention provides a method of allocating uplink packet data resources through the BTS without first communicating with the PCU. The present invention does this by reserving packet data resources before they are needed or requested and providing them to the BTS for allocation. In this way, BTS-PCU communication occurs between before an uplink connection is required and after uplink data establishment, thereby effectively eliminating BTS-PCU delays in uplink data establishment. Furthermore, the present invention provides a method of transmitting a "transmit permission message" before a communication unit requests an uplink, further reducing the uplink setup time.

[0011] refer to figure 1 -3 can understand the invention more fully, figure 1 is a logical block diagram illustrating a communication system according to a preferred embodiment of the present inventio...

Abstract

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.

Description

technical field [0001] The present invention relates generally to the field of wireless communications, and more particularly to reducing the time required to establish an uplink data connection. Background technique [0002] In the current General Packet Radio System (GPRS), the Packet Control Unit (PCU) manages, allocates and schedules the use of packet data resources needed to establish uplink packet data resources between the mobile unit and the infrastructure. To reduce the cost of deploying these systems, the PCU is placed remotely from the Base Transceiver System (BTS), which maintains the wireless link between the mobile unit and the infrastructure. When a mobile unit requests an uplink data connection, the BTS maintaining the wireless link with the mobile unit must communicate with the remote PCU to establish the required connection. In this way, the information transfer between BTS and PCU delays the link establishment. This BTS-PCU delay occurs multiple times wh...
