A method for allocating uplink semi-static resources

Abstract

The present application discloses a method for allocating uplink semi-static resources, including: determining the current bearer establishment status of the terminal; according to the bearer establishment status, allocating uplink semi-static resources for the terminal; wherein, if the currently established bearer is only Single voice service bearer and signaling bearer, no space for buffer report is reserved during uplink semi-static resource allocation; if the currently established bearer includes voice service bearer and at least one dedicated bearer, then uplink semi-static resource allocation Reserve the space for the cached amount report. By applying this application, the cell can accommodate more groups on the basis of ensuring that the data service is not interrupted.

Description

technical field [0001] The present application relates to resource allocation technology in a communication system, in particular to a method for allocating uplink semi-static resources. Background technique [0002] When the application layer on the terminal side needs to send data, it will first cache the data in the cache of layer 2 on the terminal side, wait for the base station to allocate resources, and then send the data in the cache to the base station. However, the base station and the terminal are two different network elements. The base station cannot actively know the accurate amount of data in the terminal's buffer, and needs to rely on the terminal to report the buffered amount to the base station. Therefore, whether the terminal can report the buffered amount in a timely and accurate manner will affect the base station. The timeliness and accuracy of scheduling authorization. [0003] In order to avoid resource waste caused by sending too many authorizations,...

Problems solved by technology

[0005] However, in the above method, since the effective data length of the voice service is relatively short, and the base station allocates additional space for the buffer report when allocating uplink resources, it will inevitably reduce the capacity of the group in the cell, and for many industry users, need The community can accommodate more groups

Especially for low-rate voice services, it cannot meet the needs of industry users

[0006] However, if resources are allocated for the uplink voice service, if the buffer status report space is not allocated, neither the terminal nor the eNB will process scheduling requests during the semi-static activation period. When the terminal supports many types of services, for example, the terminal supports voice services and data services at the same time , because the terminal cannot report the buffer amount in time, the data service cannot obtain uplink resources, which will cause the data service to be interrupted
