Abstract

The invention relates to a method for releasing voice multicast ascending, wherein said method presets the priority of release voice multicast ascending of distributor; in the voice multicast, and when forces to release the voice multicast ascending occupied by present user, the distributor with relative priority sends release command to MSC, MSC based on said command, release the voice multicast ascending, to set the voice multicast ascending state as free. With said invention, distributor can flexibly control the voice multicast ascending, when the user terminal occupying present ascending is accident, etc.

Description

technical field

[0001] The invention relates to the field of trunking mobile communication, in particular to a method for releasing a voice group call uplink in a trunking mobile communication system. Background technique

[0002] Trunking mobile communication is a relatively economical and flexible mobile communication system developed in the 1970s. It is an advanced development stage of the traditional dedicated radio dispatching network. The traditional dedicated radio dispatching system has poor overall planning, mixed models and standards, too many small networks, narrow coverage, severe noise interference, and waste of frequency resources. Therefore, a new radio dispatching technology--trunk mobile communication emerges at the historic moment, and is widely used in various professional departments such as transportation, public security, highway, fire protection, electric power, railway, flood control, and finance.

[0003] The so-called trunking is to use multiple wi...

Examples

Embodiment 1

[0065] This embodiment specifically analyzes the technical solution of the present invention for the situation that the service user currently occupying the uplink of the voice group call is in the Anchor.

[0066] image 3Shown is a schematic diagram of the message flow of releasing the voice group call uplink by a dispatcher with the authority to release the voice group call uplink when the service user occupying the voice group call uplink is in the cell covered by the Anchor MSC. As shown in the figure, when the VGCS is successfully established, the status flag of the VGCS managed by the Anchor MSC is "ongoing". FACCH), notify all BSSs in the cell to broadcast UPLINK_FREE message in the VGCS area, and broadcast the current voice group call up behavior idle state, if the current VGCS area has other MSCs besides the coverage cell of Anchor MSC--Relay MSC, then at the same time, the Anchor MSC notifies each Relay MSC to broadcast UPLINK_FREE message in each Relay MSC coverag...
