Problems solved by technology

[0018] However, it can be seen from Table 1 that what the Anchor MSC receives is only a VGCS or VBS release notification, and it is impossible to know the real reason why the VGCS or VBS is released according to the release notification
In particular, if the release occurs when the VGCS or VBS is established, due to insufficient network resources or network failure, the establishment of the VGCS or VBS fails and cannot be successfully established, resulting in an abnormal release. The Anchor MSC has no way of knowing the network failure, and then , it is impossible to make a corresponding reasonable treatment for the network failure, and it is impossible to eliminate the network failure, which may affect the establishment of VGCS or VBS in the future if the network failure continues

Embodiment 1

[0100] This embodiment describes the technical solution of the present invention for the case where the calling user actively requests the RelayMSC of the cell where the calling user is located to release the VGCS or VBS after the VGCS or VBS is established.

[0101] Figure 7 is a schematic diagram of the message flow for the calling service user to request the release of the VGCS from the Relay MSC after applying for uplink. As shown in the figure, after the calling service user applies for uplink, it sends a message requesting to terminate the VGCS to the Relay MSC in its cell: TERMINATION_REQ message, after the Relay MSC receives the TERMINATION_REQ message, it sends a VGCS TERMIN message to the relay group call register (Relay Group call register, referred to as Relay GCR) to instruct the Relay GCR to set the corresponding group call state as idle (IDLE), and relay The MSC returns a VGCS release message to the calling service user: TERMIBNATION message, indicating that the ...

Embodiment 2

[0107] This embodiment specifically describes the technical solution of the present invention for the situation that the channel allocation failure of the VGCS or VBS in the cell where the calling service user is located leads to the release of the VGCS or VBS.

[0108]As shown in Figure 9, after the calling service user initiates a VGCS request, when the BSS fails to allocate a channel for the service, the message flow diagram of the VGCS release initiated by the Relay MSC, and Figure 10 is the calling service user in Embodiment 2 of the present invention after initiating a VBS request , when the BSS fails to allocate a channel for the service, the message flow diagram of the VBS release initiated by the Relay MSC, as shown in Figures 9 and 10, the calling service user initiates a VGCS, or VBS request, when the MSC_R sends a VGCS_ASS_REQ request message or a VBS_ASS_REQ request message to the Relay BSS in the cell where the calling service user is located according to the VGCS...

Embodiment 3

[0113] Embodiments The technical solution of the present invention is described for the situation that the calling service user fails to establish a call control connection with the BSC in the cell where the VGCS or VBS is released.

[0114] Fig. 11 is a schematic diagram of the message flow of the VGCS release initiated by the Relay MSC when the BSC fails to establish a call establishment connection after the calling service user initiates a VGCS request. Fig. 12 is a schematic diagram of the message flow of the VBS release initiated by the Relay MSC when the BSC fails to establish the call establishment and connection establishment after the calling service user initiates the VBS request. As shown in Figures 11 and 12, the calling service user initiates a VGCS or VBS request to the Relay MSC through the Relay BSS of the network where the calling service user resides, and the Relay BBS where the calling service user resides successfully allocates a VGCS or VBS request for the ...

Abstract

The trunking communication service comprises: voice group call service (VGCS), or voice broadcast service (VBS). The method thereof comprises: in the trunking communication service releasing notice sent from Relay MSC to Anchor MSC, a cell used for indicating the reason of releasing the trunking communication service is added in order to make the releasing notice carrying the release reason; according to said release notice, Anchor MSC can either complete the release of trunk communication server or get the release reason of trunking communication service according to the parameter in the cell newly-added with the release reason.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for releasing the trunking communication service in a trunking mobile switching center initiating the release of the trunking communication service in the trunking mobile communication system. Background technique [0002] As we all know, the railway is a major artery of the national economy, and railway communication is the main artery of railway transportation and production. Establishing a safe, reliable and sustainable railway system is related to the national economy and people's livelihood. As an advanced technical system, the Global System for Mobile communication for Railway (GSM-R), which has been widely tested and applied in Europe, provides a powerful, service-rich, stable and reliable system for railway-specific communications. Comprehensive information platform. Its application prospect in our country cannot be underestimated. [0003] GSM-R is a railw...
