Traffic channel allocation method and base station

Abstract

The invention discloses a traffic channel allocation method and device. The service channel allocation method comprises the following steps: a base station receives a group call establishing request sent from a core network, and a group number and context configuration information are extracted from the group call establishing request; the base station checks states of group members registered in the base stable according to the group number; when at least one member in the group is in an idle state, the base station allocates a traffic channel to the group call to establish another group call according to the context configuration information; when all the members in the group are in a busy state, the base station adds the group number and the context configuration information to a list of group calls to be allocated with traffic channels; and moreover, after the base station releases one call, the base station allocates a traffic channel to the group call in the list of the group calls to be allocated with the traffic channels according to the subordination relation between released members and the list of the group calls to be allocated with the traffic channels. Through adoption of the method, traffic channel allocation can be in line with demands, so that the traffic channel utilization ratio is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a service channel allocation method and a base station. Background technique [0002] At present, there are mainly two methods for allocating service channels for group calls in the trunking system, and the two methods are as follows: [0003] 1. Static allocation method of traffic channels [0004] The method is based on a preset group call area, and the base station in the group call area allocates a traffic channel for the group call service. No matter whether there is a registered member of the group call within the jurisdiction of the base station, the base station must allocate a service channel for the group call. Traffic channel, this method wastes channel resources. [0005] 2. Dynamic channel allocation method [0006] In this method, the base station allocates a traffic channel for a group call to the terminals belonging to the same group wit...

Problems solved by technology

[0006] In this method, the base station allocates a traffic channel for a group call to the terminals belonging to the same group within its jurisdiction, but in practical applications, a terminal may belong to multiple different groups, so when a terminal belongs to multiple When a group initiates a group call within the same time period, the base station needs to allocate a service channel for each group call, and also allocate multiple service channels for a terminal, but a terminal can only participate in one call within a time period, which is impossible Attached to multiple service channels at the same time, therefore, the multiple service channels allocated to the terminal are a serious waste of channel resources. When the group call service is frequent, the service channels of the base station will be quickly exhausted, resulting in serious call loss.

[0007] Compared with the first static allocation method of traffic channels, the dynamic allocation method of traffic channels has certain advantages in the case of infrequent group calls, but in the case of frequent group calls, the second dynamic allocation method of traffic channels will also Serious waste of channel resources

[0008] Both of the above two methods have the problem of wasting channel resources to varying degrees. In today’s shortage of channel resources, people pay more attention to how to effectively allocate service channels for group call services, so as to achieve real on-demand allocation of service channels and rational use of service channels. purpose of channel
