Method, device and base station for preempting resources

Abstract

The invention discloses a method, a device and a base station for preempting resources. The device comprises a first judgment module, a second judgment module, a third judgment module, a release module and a processing module, wherein the first judgment module is used for judging whether amount of available resources is smaller than the amount of resources required by a call service to be accessed, and / or whether the power is overloaded; the second judgment module is used for judging whether an accessed call service exists of which the priority is lower than the priority of the call service to be accessed; the third judgment module is used for judging whether the amount of resources of the accessed call service is larger than or equal to the amount of resources to be released; the release module is used for releasing resources of which the amount is equal to the amount of the resources to be released from the accessed call service; and the processing module is used for establishing channel resources and allocating power resources for the call service to be accessed. By releasing resources of the low-priority accessed call service, establishing channel resources of the call service to be accessed and allocating power resources, in the method, the device and the base station, enable the talk can be accessed into the call service to be accessed, the call successful rate of the high-priority call service is improved, and ensures the communication timeliness of the call service is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource preemption method, device and base station. Background technique [0002] In the prior art, mobile communication systems based on Code Division Multiple Access (CDMA) standard support call service modes including but not limited to: ordinary voice call service, data call service, emergency call service, group call service and private call business. To meet the various calling needs of different users. [0003] The above-mentioned mobile communication system based on the CDMA system has limited internal data capacity, which is limited by resources such as power resources and channel resources. When the system load reaches the data capacity limit, network congestion will occur. At this time, when the terminal initiates a new call request to the system, the call cannot be established due to insufficient resources. [0004] In order to prevent the phenome...
