Admission control method of carrier aggregation system

Abstract

The application discloses an admission control method of a carrier aggregation system. The method comprises the following steps: (A) accounting the time-frequency resource service condition on all component carriers in a cell by a base station; (B) determines whether the idle time-frequency resources on all component carriers can meet requirement for time-frequency resources of a bearer requested by a bearer admission request after receiving the bearer admission request by the base station, if yes, executing step (C), and if no, executing step (E); (C) determining whether a non-overloaded configuration component carrier exists in configuration component carriers of user equipment sending the bearer request, if yes, executing step (D), and if no, executing step (E); (D) returning admission decision success, and stopping the process; (E) returning admission decision failure, and stopping the process. The technical scheme provided by the application can avoid the problem that a bearer establishment request is refused, which is caused by lack of spare resources of individual component carriers, and can prevent new access service form influencing the service quality of existing services on some component carriers with heavy loads.

Description

technical field [0001] The present application relates to the field of mobile communication technologies, in particular to carrier aggregation technology, and in particular to an admission control method in a carrier aggregation system. Background technique [0002] The development of mobile communication technology has gone through the development process from the first generation (1G), the second generation (2G), the third generation (3G), and the evolution to the third generation (E3G). In today's increasingly tight spectrum resources, how to support a larger bandwidth on the existing spectrum resources for the next generation wireless communication network has become a key factor to improve the service data transmission rate and enhance the user experience, and is facing severe challenges. At present, the 3rd Generation Partnership Project (3GPP) proposes in LTE-A to use carrier aggregation (CA) technology to fully utilize the spectrum resources scattered in multiple fre...

Problems solved by technology

[0011] This application provides an admission control method in a carrier aggregation system, which can avoid the problem that the bearer establishment request is rejected due to insufficient remaining resources of individual component carriers, and prevent new access services from being used on certain component carriers with heavy loads.
