A channel resource allocation method and base station

Abstract

A method and a base station for allocating channel resource are disclosed for solving the problems that transmission of low priority messages are delayed because of message priority differences or network performance decreases when transmitting different messages using channel resource of a same channel. During the process of transmitting the at least two kinds of messages using the channel resource of the same channel, priority adjustment parameters indicating resource preempted situations are acquired based on the transmission statuses of at least two kinds of messages, the transmission priorities of the at least two kinds of messages are adjusted based on the priority adjustment parameters, and the at least two kinds of messages are transmitted using the channel resource of the channel and the adjusted transmission priorities. The priority of one kind of messages is raised when the transmission resource of this kind of messages is preempted overmuch, therefore the situations are avoided that the transmission delays of the low priority messages are higher or the low priority messages are unable to be transmitted due to the fact that resource is preempted by high priority messages all the time. The rationality of channel resource utilization is improved.

Description

technical field [0001] The invention relates to resource allocation in a mobile communication system, more specifically, a channel resource allocation method and a base station. Background technique [0002] In GSM (GlobalSystemofMobilecommunication, Global System for Mobile Communications), CCCH (CommonControlChannel, common control channel) can be divided into PCH (PagingChannel, paging channel) and AGCH (AccessGrantChannel, grant access channel), where: [0003] PCH is used by the base station to page the mobile station; [0004] The AGCH is used to respond to the base station's random access request to the mobile station, that is, to allocate a SDCCH (Standalone Dedicated Control Channel, independent dedicated control channel) or directly allocate a TCH (Traffic Channel, traffic channel). [0005] According to different channel combination types, each CCCH has several CCCH blocks, and these CCCH blocks are configured as AGCH blocks and PCH blocks according to the parame...

AI Technical Summary

Problems solved by technology

[0007] In the case of sudden large network traffic and sudden increase of high-priority messages, the resources available for low-priority messages will decrease sharply, delaying the sending of low-priority messages, and in severe cases may also cause message overflow and affect network performance

[0008] For example, it is assumed that immediate assignment messages are given priority, but in certain business scenarios, immediate assignment messages increase in large numbers, but since immediate assignment messages are given priority, a large amount of CCCH block resources will be occupied at this time, resulting in paging messages being unable to be scheduled due to their low priority sent, affecting network performance

[0009] The above uses CCCH block resources, paging messages and immediate assignment messages as examples to illustrate the problems existing in the prior art, but the above shortcomings also exist in the scenario of using the same resource to send different messages
