Problems solved by technology

[0006] To sum up, since the mobile station needs to feed back the confirmation message to the assignment message issued by the network side during the downlink resource allocation process of the GPRS system, the mobile station side starts to send the response message from the complete reception of the downlink assignment message to the confirmation message. There is a certain time delay, which not only affects the allocation speed of system downlink resources, but also, within this time delay, network resources are not used by the network and any users, and system resources are wasted

Embodiment Construction

[0025] In the present invention, after the network side sends the current downlink packet link assignment message to the mobile station, it directly sends the data block to the mobile station, thereby eliminating the need for the mobile station to completely receive the downlink packet link assignment message and reply the response message. The delay in the process improves the utilization rate of system resources.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 2 As shown, the system for allocating downlink resources in the GPRS system of the present invention includes a mobile station 1 and a corresponding wireless network. Wherein, the wireless network includes a base station 2 for delivering information to the mobile station, a base station controller 3 corresponding to the base station 2, and a core network 4 .

[0028] The core network 4 sends the current downlink packet link assignm...

Abstract

The invention discloses a system and method for resource allocation under GPRS system. The system includes a mobile station and a corresponding radio network, wherein the radio network delivers the information of current downlink grouped link assignment to the mobile station, and also delivers data block to the mobile station according to the information of downlink grouped link assignment, while adding poll information to the delivered data block; the mobile station receives the information of downlink grouped link assignment, data block and poll information, and responds to the radio network with the poll responding information. The method includes the following steps: the network side delivers the information of current downlink grouped link assignment to the mobile station; the network side delivers data block to the information of downlink grouped link assignment and adds poll information to the delivered data block; the mobile station responds to the network side with the poll responding information according to the status of data block reception.

Description

technical field [0001] The present invention relates to a mobile communication technology, in particular to a system and method for allocating downlink resources in a GPRS (General Packet Radio Service, General Packet Radio Service) system. Background technique [0002] GPRS is a mobile packet data service developed on the basis of the existing Global System for Mobile Communications. GPRS supports data transmission in packet mode by introducing packet switching functional entities in the global digital mobile communication network. The GPRS system can be regarded as a business expansion of the circuit switching system in the original Global System for Mobile Communications to meet the needs of users to access the Internet or other packet data networks with mobile terminals. [0003] During the downlink packet forwarding process of the GPRS system, the downlink assignment message is used to initialize the data packet sent to the mobile station in the ready state. When ther...
