Description
Technical field
The present invention relates to the wireless communication field group-calling service, specially refer to mobile switching centre and speaker's information uploading method thereof in the group calling monitoring.
Background technology
GSM-R is the comprehensive special digital mobile communication system that designs for railway communication specially, it is based on the infrastructure of GSM and the voice scheduling business (ASCI) that provides thereof, wherein comprise the multipriority preemption of enhancing and toll breakdown (eMLPP), voice group call service (VGCS) and voice broadcast service (VBS), and provide railway distinctive dispatching services.Voice group call service, (Voice Group Call Service VGCS), has defined a kind of by the point-to-multipoint voice communication mode of participating in many ways, listening in many ways to be called for short group calling.The VGCS business has broken through the limitation of point-to-point communication, can set up group calls in several in simple and direct mode, realizes specific functions such as dispatch control, emergency notice, is particularly useful for the train traffic control traffic department of railway.
The member who includes two kinds of identity in the VGCS business: dispatcher and mobile service user.The dispatcher can be that the mobile subscriber also can be the fixed network user, and the dispatcher uses a pair of dedicated channel separately, and any dispatcher can talk at any time, and mobile dispatcher can be in group call region.5 dispatchers can be arranged at most in the group calling, also can not have.The mobile service user is meant the mobile subscriber of some group ID that contracted, and all mobile service users only take a Traffic Channel in the middle of group calling is carried out, and a mobile service user speech can only be arranged at one time, and the mobile service user must be in group call region.Dispatched users can also be heard other proprietary speeches except hearing own sound; The service-user of listening to can be heard proprietary sound.The dispatcher allows to talk at any time to need not to send and wants the signal of talking, and the service-user of wanting to speak must send and wants the signal of talking.
Fig. 1 is user's uplink takeover of group calling channel schematic flow sheet in the prior art.As shown in the figure, step 100～step 102: Controlling MSC (Mobile Switching Center-A, MSC-A) according to the mobile user identification in the upstream request acknowledge message, visit VLR obtains the VGCS additional information, be new speaker's mobile user comprehensive service digital net (MSISDN) number, and new speaker's MSISDN is sent to all Tandem Mobile Switching Center (MSC-B) by the occupied message of up channel.If up link is busy, for preferential speaker, MSC-A checks the relevant information that new speaker contracts, and obtains new speaker's VGCS additional information such as MSISDN from VLR.Step 104:MSC-A sends VGCS additional information message to the BSS of all its administrations, wherein carries new speaker's MSISDN.Step 106: (Base Station Subsystem BSS) broadcasts the VGCS additional messages to all hearers to base station sub-system, is new speaker's MSISDN comprising the additional information that obtains from MSC-A.
Therefore, existing speaker seizes in the group-calling channel process, and listening center can't obtain current speaker's information.When especially the speaker changed in the group calling, listening center can't obtain new speaker's information.
Summary of the invention
Main purpose of the present invention is for passing through at (the Mobile Switching Center of mobile switching centre, intercepting MSC) and between the listening center increases Supplementary Service Code, speaker's information and the action type that the indication speaker changes in the interface, give listening center current speaker's information band when the speaker changes in group calling, make listening center learn current speaker's information.
For solving the problems of the technologies described above, the present invention proposes a kind of group calling mobile switching centre in monitoring, comprise that speaker's information intercepts module, be used to intercept the speaker to obtain speaker's information; Supplementary Service Code is intercepted module, is used to intercept the Supplementary Service Code that the indication speaker changes; Reporting module transfers to listening center by intercepting interface with speaker's information and Supplementary Service Code.
Preferably, speaker's information is intercepted speaker's information that module obtains and is comprised new speaker's information and/or former speaker's information.
Preferably, during common speaker's busy channel or preferential speaker when seizing channel, reporting module transfers to listening center with speaker's information and Supplementary Service Code.
Preferably, when preferential speaker seized channel, if uplink idle, reporting module transferred to listening center with the action type of Supplementary Service Code, new speaker's information, the new speaker's busy channel of indication.
Preferably, comprise that also action type intercepts module, be used to intercept indication speaker channel occupancy and discharge the action type that channel carried out; Reporting module also is used for, and by intercepting interface action type is transferred to listening center.
Preferably, action type comprises the action type of indicating new speaker's busy channel and/or indicates former speaker to discharge the action type of channel.
The invention allows for a kind of speaker's information uploading method of mobile switching centre, may further comprise the steps speaker's information and intercept module and intercept speaker's information, Supplementary Service Code is intercepted module and is intercepted Supplementary Service Code; Reporting module by intercept interface with Supplementary Service Code and speaker's message transmission to listening center.
Preferably, described speaker's information is intercepted described speaker's information that module obtains and is comprised new speaker's information and/or former speaker's information.
Preferably, during common speaker's busy channel or preferential speaker when seizing channel, described reporting module transfers to described listening center with described speaker's information and described Supplementary Service Code.
Preferably, further comprising the steps of: action type is intercepted module and is intercepted action type; Reporting module transfers to listening center by intercepting interface with described action type.
Preferably, described action type comprises the action type of indicating new speaker's busy channel and/or indicates former speaker to discharge the action type of channel.
To sum up, the present invention increases Supplementary Service Code, speaker's information and the action type that the indication speaker changes by intercepting between mobile switching centre and listening center in the interface, make that mobile switching centre can be sent to listening center to current speaker's information and operation information when the speaker changed in the group calling snoop procedure, so that listening center learns when current speaker's information and current speaker obtain speaking right, when discharge speaking right.
