Abstract

The invention provides a group call preemption method based on a priority. The method comprises steps: when a new group call service is initiated, if the group call capacity of a cluster system is limited, resources of a group call with a low priority are preempted via an eNodeB, and a group call with a high priority is built. When group call preemption only happens to part of cells in one group call in the eNodeB, once the cell has idle group call resources, the eNodeB, restores the group call. The invention also provides a group call preemption system based on the priority. The system comprises a receiving unit, an analysis unit, a judgment unit, a release unit, a building unit and a sending unit. Preemption of a group call downlink channel is truly realized, and preemption of a group call to a group call is completed.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a priority-based group call preemption method and system. Background technique

[0002] The most basic service provided by the trunking system is a voice group call service (Voice Group Call Service, VGCS). VGCS allows a user to establish calls among multiple users belonging to a given service area and cluster group with the same group ID. The quality of service (Quality of Service, QoS) parameter of the point-to-point bearer in the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) specification stipulates a priority, which is used for service admission control. The base station (Evolved Node B, eNodeB) implements bearer preemption according to the bearer priority, so as to preempt service resources with low priority for preferential access to high priority services.

[0003] The preemption of the group call in the existing trunking system is o...
