Problems solved by technology

[0026] However, in the above solution, after the BSS sends the last Uplink Free and before releasing the group call channel, if an MS joins the group call channel, since the Uplink Free will not be sent repeatedly, the MS cannot detect the message and will not report it Listener Detect, so that the network side does not know that an MS has joined the group call channel, and still executes the local release process to release the group call channel. As a result, the MS is still in the group call after the group call channel is released, but the MS cannot occupy the uplink. Unable to listen to the voice of speakers in other cells, the terminal holder feels that the group call function is unavailable

Embodiment 4

[0058] Embodiment 4 of the present invention: a base station subsystem.

[0059] The system includes: a control unit, used to stop broadcasting a group call notification message; and / or a message sending unit, used to send a Channel Release message; a group call channel release unit, used to release the group after learning that the control unit stops broadcasting a group call notification message. Call channel, or used to release the group call channel after learning that the message sending unit sends a ChannelRelease message.

[0060] The above control unit stops broadcasting the group call notification message at the same time as or after the BSS sends the Uplink Free message for the last time.

[0061] The system further includes a delay unit, which is used to delay the set time after the above-mentioned control unit stops broadcasting the group call notification message, and then allow the BSS to execute the next process step.

[0062] The above-mentioned group call cha...

Abstract

The invention discloses a method of releasing group call channel and base station subsystem (BSS), where after stopping broadcasting group call notification message, and / or issuing Channel Release message, the BSS releases the group channel so as to assure no mobile station park on the group call channel, able to effectively solve the abnormal problem of mobile station in the course of downlink detection of group call channel release and improving the robustness of downlink detection function.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a group call channel release technology. Background technique [0002] Voice Group Call Service (Voice Group Call Service, referred to as "VGCS") and Voice Broadcast Service (Voice Broadcast Service, referred to as "VBS") are both multi-party voice communication methods in the field of mobile communication, breaking through the limitations of point-to-point communication, Ability to quickly set up calls. These two services can be collectively referred to as group call services. [0003] Simply put, VGCS is to realize the business that multiple people can speak and more people can be listeners. [0004] There are two types of business members in the VGCS business, that is, dispatchers and business users. The dispatcher can be a fixed network user or a mobile user, and participate in group call voice communication through the dedicated channel established by the network. In t...
