Problems solved by technology

[0043] In the prior art, when a Class B MS under GPRS is in packet transmission mode, it will monitor PTCH, but will not monitor CCCH, PCCCH or SACCH, so it cannot know the group Call related information, for example: NLN value
Specifically, when a new group call / broadcast call is initiated in the cell, the NLN value changes, but because the B-class MS under GPRS is in the packet transmission mode, it will only monitor PTCH, but will not monitor CCCH, PCCCH or SACCH, so the MS will have no way of knowing that the NLN value has changed

Embodiment 2

[0071] The second preferred embodiment of the present invention: a base station subsystem, comprising a message sending module for sending a message including a notification list number NLN on the packet-associated control channel PACCH. The message sending module is further configured to send a message on the PACCH, where the message includes group ID information of all group calls being performed in the current cell, and / or the highest priority information of all group calls being performed by the current cell, and / or Emergency mode status identification information of the current cell.

Embodiment 3

[0072] The third preferred embodiment of the present invention: a group call communication system, including a base station subsystem BSS and a mobile station MS, the BSS includes a message sending module, and the module is used to send a message including a notification list number NLN on the packet associated control channel PACCH message; MS includes a message receiving module and a judging module, the message receiving module is used for receiving the above-mentioned message containing NLN, and the judging module is used for judging whether the NLN received by the MS is the same as the NLN saved by the MS itself, if not, the MS leaves the packet transmission mode, enter the group idle mode.

[0073] The message sending module of the BSS can also be configured to send a group call notification message on the group paging channel PPCH, and the MS monitors the group call notification message on the PPCH when the MS is in the group idle mode. If the MS in the group idle mode b...

Abstract

The invention discloses a group calling communication message delivery method, a base station subsystem and a group calling communication system. In the group calling communication message delivery method, the base station subsystem sends a message including a notify list number on a packet associated control channel to ensure that a mobile station in a mode of packet transmission obtains the notify list number message related to the group calling; when a new group calling or a broadcast call is sent in a cell, the mobile station can get the changes in the notify list number value.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a group call communication technology. Background technique [0002] Voice Group Call Service (VGCS, referred to as "VGCS") and Voice Broadcast Service (Voice Broadcast Service, referred to as "VBS") are both voice communication methods in the field of mobile communication, which break 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 (or group call) services. [0003] To put it simply, VGCS is a business where multiple people can speak and more people can be listeners (the number of listeners is unlimited). [0004] The VGCS service includes service members with two identities, namely dispatchers and service users. Dispatchers can be fixed network users or mobile users, and participate in group call voice communication through the dedicated channel established f...
