Problems solved by technology

[0004] However, for the scenario where CBTC services and voice services are concurrent, since CBTC services control the train running, high priority guarantee is required. If dynamic scheduling is used for voice, the priority of CBTC services can be guaranteed to be higher than that of voice services, but voice services cannot be saved. PDCCH resources, in the scenario where PDCCH resources are limited, may cause abnormal phenomena such as word loss and freeze in voice services. If SPS scheduling is used for voice services, although PDCCH resources can be saved, it cannot guarantee that CBTC services have higher priority than voice services. This makes the CBTC business not get priority protection, and there are security risks

Abstract

Embodiments of the present invention provide a radio resource scheduling method and device, wherein the method includes: acquiring the radio bearer RB utilization rate of target priority services in a cell in the current period; if the RB utilization rate is higher than a preset threshold, Then reduce the SPS resource configuration ratio of the cell; if the RB utilization rate is lower than a preset threshold, increase the SPS resource configuration ratio of the cell. The embodiment of the present invention can flexibly configure the SPS resources of the cell under the condition of ensuring service priority, so as to save wireless resources and improve the utilization rate of wireless resources.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for scheduling wireless resources. Background technique [0002] Long Term Evolution (LTE for short) wireless communication technology is gradually applied to urban rail transit, such as subway, light rail, etc. There are various types of services under this network, such as Communication Based Train Control System based on wireless communication System, referred to as CBTC), voice, video, and ordinary packet switching (PS) data services. CBTC services are deployed on QCI1, voice services are deployed on QCI1, video services are deployed on QCI4, and ordinary PS data are deployed on QCI9. According to the characteristics and requirements of different businesses, differentiated treatment is carried out. [0003] Among them, the CBTC service belongs to the rail transit unmanned train control signaling, which is mainly use...
