Problems solved by technology

When the group service is established, it is necessary to allocate downlink shared radio resources in all the cells included in the group service establishment area and broadcast the paging message for the group service establishment, but the actual situation is that most of the cells in this area do not have the group service This will inevitably cause a serious waste of system wireless resources and affect the performance of other cluster services in the area

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] In the embodiment of the present invention, since group users can be attached to different mobility management devices, each mobility management device will maintain a local group service establishment area for the group, and then can obtain the corresponding Cluster group service establishment area. When the trunking group service is initiated, downlink shared radio resources are not transmitted in a fixed area, but resources are allocated in cells included in the trunking group service establishment area. Moreover, the cluster group service establishment area can also be updated. Therefore, the waste of system wireless resources is avoided

Abstract

A cluster group service building method includes the steps that when group users belonging to the same group perform startup and attachment, the mobile management device to which the group users are attached allocates group user tracing area lists to the group users, and the group user tracing area lists of the group users belonging to the same group are combined into local group service building areas; the local group service building areas in the same group are combined to obtain a cluster group service building area; when the same group starts cluster group service, downlink shared wireless resources are allocated in cells contained in the cluster group service building area and the cluster group service is built. After the method is in use, resources can be allocated in the cells contained in the cluster group service building area, and waste of the wireless resources of a system is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to a method for establishing a cluster group service. Background technique [0002] The group service is a typical service in the trunking system, which is jointly participated by multiple users, such as group call. In the process of group service establishment, in order to achieve fast call establishment, the downlink generally adopts broadcast mode to send control plane signaling and user plane data, and the group users in the idle state can directly receive the control plane signaling and user plane data without changing to the connected state. User plane data, thereby speeding up call establishment and service data reception. [0003] Since the cluster group users are scattered in different cells of the same base station or different cells of different base stations, and the mobility management devices attached to the terminals are different, the state...
