Abstract
The method applicable to wireless dispatch system includes following steps: building first data base to store terminal number of dispatcher, and coincidence relation between VLR numbers of MSC distributed in dispatch area; building second data base to store terminal number of dispatcher, and coincidence relation between sub zone numbers of VMSC distributed in dispatch area. Dispatcher starts up calling, GMSC looks first data base, which allows calling of dispatcher to route to VMSC distributed in dispatch area, and restricting calling of dispatcher to route to VMSC not included in dispatch area. VMSC in dispatch area looks up second data base, allowing connecting dispatcher and calling between called terminals in sub zone in dispatch area, and restricting calling between called terminals in sub zone not in dispatch area. based on whether the sub zone number the called mobile terminal locates at is in dispatch area or not, GMSC/VMSC restricts calling.
Description
Technical field
The present invention relates to mobile communication technology, the systems such as railroad train wireless dispatching, vehicle on highway scheduling and river boats and ships wireless dispatching that relate to or rather in the mobile communication system particularly are to the method for limiting of calling area.
Background technology
In the hauling operation of railway, highway, river one class, train, automobile, boats and ships etc. generally all are to move toward a direction apace in a period of time, thereby when realizing the wireless dispatching operation, can be the linear mobile communication system that covers by the sub-district and handle.
With the train dispatching is that example illustrates the calling area restricted problem in its wireless dispatch system.In the middle of the wireless dispatching of railroad train, each dispatcher has definite scheduling compass of competency, and each dispatcher has right scheduling is train in its compass of competency.Because train is in the middle of high-speed cruising, the dispatcher possibly can't confirm the position of this train in some time periods, therefore the dispatcher when the train operator sends instruction, train has often left his dispatcher-controlled territory; On the other hand, for convenience the train operator converses with the dispatcher, and all dispatchers use same cornet, can't confirm that when the train operator receives dispatcher's instruction this instruction is whether from the dispatcher of one's respective area.Cause train operator's execution error instruction in these cases probably or can not operate by right instructions in time, therefore in railway wireless train dispatching patcher, must provide the calling area limitation function, promptly allow the dispatcher to call out the interior mobile subscriber of its dispatcher-controlled territory, the restriction dispatcher calls out the not mobile subscriber in its dispatcher-controlled territory.
As shown in fig. 1, the dispatcher has the right to administer the train in its dispatcher-controlled territory 11, then will carry out restriction call to its dispatcher-controlled territory 11 outer trains.Therefore, in the schedule job of railway wireless train, railway wireless train dispatching patcher should be able to limit the dispatcher and call out the train operator exceed its dispatcher-controlled territory, so as not to the dispatcher instruction is sent to should not be by the object of its scheduling, i.e. Cuo Wu object.
In like manner, in the schedule job of highway wireless vehicle, and then in the wireless ship dispatch operation in river, object moves, all can have this restricted problem to calling area when its position is uncertain as long as be scheduled.
It still is example with the train dispatching, in order to limit the train operator that the dispatcher calls out not at its dispatcher-controlled territory, before calling out train operator's success, the dispatcher at first needs to determine the position of train so, usually adopt location technology to determine train position, location technology commonly used has satellite fix, as global positioning system (GPS:Global Positioning System), global system for mobile communications (GSM:Global Systemof Mobile communications) location technology location service (LCS:Location Service) etc.; In the call handling process before call setup, increase a determination point simultaneously, promptly whether can call out this train operator, adopt the data base querying technology of positional information to adjudicate usually according to train current location decision dispatcher.
In the prior art with dispatching desk as calling out determination point, dispatching desk obtains the train current location information from train control system.Train control system is the part in the Railroad Communication System, and it can collect the two-dimensional position information (at the side-play amount of certain position reference point) of train in the railway linear system.Dispatching desk also is the part of Railroad Communication System, and dispatching desk is connected with train control system by wide area network/local area network (LAN) (WAN/LAN:Wide Area Network/Local Area Network).When dispatching desk made a call, the interface that utilizes train control system to provide was inquired about the current location information of train, after obtaining the current location information of train, judges whether the dispatcher can initiate the dispatch call at this train operator again.
Existing calling area limitation function solution shown in Fig. 2.The dispatcher is by the current location of WAN/LAN (not shown) to train control system inquiry train travelling carriage, obtain the just train position information in sub-district 2 of train, because not in the dispatcher-controlled territory 21 of this dispatcher's administration, so limit the train operator that its calling is positioned at sub-district 2.Inquire about the current location of train to train control system by the WAN/LAN (not shown) as the dispatcher, obtain the just train position information in sub-district 1 of train, because sub-district 1 is in the dispatcher-controlled territory 21 of this dispatcher's administration, so allow the dispatcher to call out the train operator who is positioned at sub-district 1.In above-mentioned call handling process,, thereby, can get access to the current location information of train as long as inquire about train control system because train control system is the real-time tracking train.
There is the problem of two aspects in prior art solutions:
For the railway wireless dispatch application, call setup is an important need that guarantees scheduling safety fast, but this technical scheme all will be inquired about the train current location information by the WAN/LAN network in train control system before per call is set up, call set-up time is prolonged; In order to allow dispatching desk can from train control system, inquire the current location information of train, need set up the WAN/LAN network, increased investment.
During the wireless dispatching that same defective also is present in the automobile wireless dispatch application of highway and river boats and ships is used.
Summary of the invention
The objective of the invention is to design a kind of calling area method for limiting, defective when overcoming existing techniques in realizing calling area limitation function, can effectively shorten call set-up time, also need not simultaneously to set up the WAN/LAN network, saved investment in order to inquire about (train) control system (current location information of inquiry train).
The technical scheme that realizes the object of the invention is such: a kind of calling area method for limiting, whether judgement callee's current location is in the dispatcher-controlled territory of dispatcher's administration, then allowing the dispatcher to call out, then do not limiting dispatcher's calling, it is characterized in that:
Also comprise, set up first database that the GMSC (gateway mobile switching center) of a mobile communication system can have access to, be used to preserve the corresponding relation between the VLR Visitor Location Register number of the mobile switching centre that dispatcher-controlled territory distributed of the employed termination number of dispatcher and this dispatcher administration; Set up second database that the visit ground mobile switching centre of a mobile communication system can have access to, the dispatcher-controlled territory that is used to preserve the employed termination number of dispatcher and this dispatcher administration the corresponding relation between the cell id of mobile switching centre with being distributed in this visit;
Described judgement further comprises:
A. the GMSC (gateway mobile switching center) of mobile communication system is inquired about first database, dispatcher's calling is routed to the visit ground mobile switching centre that dispatcher-controlled territory distributes, and restriction dispatcher's calling is routed to the visit ground mobile switching centre that does not comprise dispatcher-controlled territory;
B. second database is inquired about by the visit of mobile communication system ground mobile switching centre, allow to connect the calling between dispatcher and the called mobile terminal in its dispatcher-controlled territory sub-district, and restriction dispatcher and the not calling between the called mobile terminal in its dispatcher-controlled territory sub-district.
Described steps A further comprises:
A1. the GMSC (gateway mobile switching center) of mobile communication system is handled the dispatcher and is called out, and obtains the called mobile terminal roaming number according to the called number in dispatcher's call information, and this roaming number contains VLR Visitor Location Register number;
A2. GMSC (gateway mobile switching center) is inquired about first database, obtains and number tabulation of the corresponding VLR Visitor Location Register of the employed termination number of this dispatcher;
A3. from the called mobile terminal roaming number that steps A 1 is obtained, separate VLR Visitor Location Register number, number in the VLR Visitor Location Register that obtains with the steps A 2 number tabulation carries out matching operation, route the call to corresponding visit ground mobile switching centre during coupling, call release then when not matching;
Described step B further comprises:
B1. visit ground mobile switching centre paging called mobile terminal, obtain the cell id at the current place of called mobile terminal;
B2. inquire about second database, obtain and the corresponding cell id tabulation that is distributed in corresponding mobile switching centre of the employed termination number of this dispatcher;
B3. the number in cell id that step B1 is obtained and the step B2 cell id tabulation of obtaining carries out matching operation, then adjudicates during coupling in its dispatcher-controlled territory, then adjudicates when not matching to not in its dispatcher-controlled territory.
In the described steps A 1, obtaining the called mobile terminal roaming number is to operate the SRI that sends routing information by initiating MAP MAP, replys from sending routing information and obtains the called mobile terminal roaming number the SRIack.
Among the described step B3, adjudicate further call release into not in its dispatcher-controlled territory the time.
Described first database can be the internal database that is based upon in the described GMSC (gateway mobile switching center), or is based upon the outer external database of described GMSC (gateway mobile switching center); Described second database can be the internal database that is based upon in the described visit ground mobile switching centre, or is based upon the external database outside the described visit ground mobile switching centre; Described first database and second database can also be arranged in the same external server.
The key problem in technology of realizing the inventive method is to utilize the information in the call handling process to carry out the judgement whether dispatcher can call out train (or automobile or boats and ships etc.) driver in GMSC (gateway mobile switching center)/visit ground mobile switching centre (GMSC/VMSC:Gateway MSC/Visited MSC).
The present invention utilizes the cell id of sub-district, the current place of train (or automobile or boats and ships etc.) driver and the foundation that the relation between dispatcher's dispatcher-controlled territory is adjudicated as calling; In GMSC (gateway mobile switching center)/visit ground mobile switching centre (GMSC/VMSC) procedure for processing call, adjudicate.
Calling area method for limiting of the present invention can solve two major defects of prior art scheme:
Because when judgement, when inquiry be internal database the time, will be very little to the influence of call set-up time, its time delay＜100ms when inquiring about by the mobile communication system internal bus;
Current, this calling area limitation function just can be realized in existing railway global system for mobile communications (GSM-R:GSM for Railway), only need software alteration, do not need to increase new hardware device, obtaining the train current position information is the cell id of its sub-district, place, rather than two-dimensional position information, need not set up the WAN/LAN that is connected with train control system simultaneously for the current location of inquiring about train yet, saved investment.

Embodiment
Still calling out the train operator with the dispatcher is example, owing to call out in train operator's the call handling process the dispatcher, the cell id at the current place of train operator must will be used, and in railway global system for mobile communications (GSM-R), generally the border of dispatcher-controlled territory is overlapped with cell boarder by the network planning, be that dispatcher-controlled territory is made up of the sub-district of one or more GSM-R, therefore can be in the railway global system for mobile communications, the database of corresponding relation between the dispatching cell in built-in scheduler person and the dispatcher compass of competency, handle in the process of dispatcher's calling in the railway global system for mobile communications, just can whether allow or limit the judgement that the dispatcher calls out according to this database data.
In the GSM-R communication system, the dispatcher-controlled territory of each dispatcher's administration is planned by the sub-district of GSM-R usually, no matter dispatcher's calling is how to search out train operator (mobile subscriber) by the GSM-R network, and final GSM-R only sets up speech channel between could be for dispatcher and train operator (mobile subscriber) behind the cell id of knowing train operator (mobile subscriber) place.
The present invention program is by being provided with the database that GMSC (gateway mobile switching center)/visit ground mobile switching centre (GMSC/VMSC:Gateway MSC/Visited MSC) can have access to, in database, set up the corresponding relation between the dispatching cell in dispatcher and the dispatcher compass of competency, define dispatcher's dispatcher-controlled territory, realize calling area limitation function by this way based on the GSM-R sub-district.
Referring to Fig. 3, under GSM-R network typical case networking situation, the present invention solves the technical scheme of calling area limitation function shown in the figure.
Do following description agreement earlier:
Under complicated situation, the dispatcher-controlled territory of dispatcher's administration can be distributed in plural mobile switching centre (MSC:Mobile Switch Centre) overlay area, though being distributed in two MSC overlay areas is a kind of typical situations, can represent all dispatcher-controlled territories to be distributed in the situation of a plurality of MSC overlay area;
When dispatching, the dispatcher can use fixed terminal, also can use portable terminal, but from the railway dispatching operation process, even using portable terminal dispatches, the position that dispatching desk and dispatcher carry out scheduling operation can not change easily, and is therefore the same with the situation that adopts the fixed terminal scheduling substantially, promptly in one period metastable time period, when the dispatcher used terminal to make a call, it a little was constant that first of its access GSM-R network accepted;
Dispatcher's fixed terminal can be the terminal of integrated services digital network (ISDN:Integreted ServiceDigital Network) network, also can be the terminal of direct-connected private branch Private Branch Exchange PBX (PBX:PrivateBranch Exchange).Under actual networking situation, isdn network or PBX can be connected to the GMSC (gateway mobile switching center) (GMSC) of GSM-R network, also can be connected to mobile switching centre (MSC), that is to say that this moment, the dispatcher called out that to insert that first of GSM-R network side accepts a little can be that GMSC also can be MSC when calling out the mobile subscriber.
And dispatcher's mobile dispatch terminal is when making a call, and calls out to insert first of GSM-R network side and accept and a little be MSC.Since first to accept a little be MSC, then MSC must possess the function of GMSC, finishes the process of inquiry callee roaming place.
MSC2 shown in Figure 3, MSC3, MSC1 all have the function of GMSC and VMSC concurrently.
In GMSC, built-in first database is used to preserve the corresponding relation between the VLR Visitor Location Register (VLR:Visitor Location Register) number of the mobile switching centre that dispatcher-controlled territory distributed (MSC) of the employed termination number of dispatcher and this dispatcher administration; In VMSC, the dispatcher-controlled territory that built-in second database is used to preserve the employed termination number of dispatcher and this dispatcher administration is distributed in the corresponding relation between the cell id of this VMSC.Set up the corresponding relation between the sub-district in dispatcher and the dispatcher compass of competency therefrom.During enforcement, first, second database also can be external, perhaps is arranged in the same external server, as long as GMSC and VMSC can have access to.
After GMSC receives dispatcher's calling, initiate MAP (MAP:Mobile Application Part according to called number, English operation name in the GSM standard) operates (the SRI:Send Routing Information that sends routing information, English operation name in the GSM standard), reply (SRI ack what operation sent routing information, English operation name in the GSM standard) obtains Mobile Station Roaming Number (MSRN:Mobile Subscriber Roaming Number) in, promptly from attaching position register (HLR), obtain MSRN.This roaming number comprises VLR Visitor Location Register (VLR) number, promptly MSRN=VLR number+3 random numbers (heterogeneous networks because coding rule difference, MSRN and VLR number length is possible inequality).Earlier from Mobile Station Roaming Number (MSRN), peel off (extraction) VLR number, number in VLR Visitor Location Register (VLR) number tabulation of corresponding relation is arranged (because dispatcher-controlled territory may be distributed among a plurality of VMSC with the employed termination number of this dispatcher again with in first database, therefore be the tabulation of VLR Visitor Location Register number) do matching operation (owing to mate with tabulation, therefore this matching process may once just can not finished), if the match is successful, call out and continue, otherwise call release.
After calling is routed to VMSC, VMSC paging train operator, obtain the cell id at the current place of train operator, there is the number (being distributed in the cell list of corresponding MSC) in the cell id tabulation of corresponding relation to make coupling with what preserve in cell id and VMSC side second database with the employed termination number of this dispatcher (owing to mate with tabulation, therefore this matching process may once just can not finished) operation, if the match is successful, call out and continue (allowing the dispatcher to call out the train operator), otherwise call release (the restriction dispatcher calls out the train operator).
Among Fig. 3, through said process, the restriction dispatcher calls out the train operator in the MSC1 compass of competency, allows the dispatcher-controlled territory to this dispatcher's administration, and promptly part is called out by the train operator in MSC2, the MSC3 compass of competency 31.
Referring to Fig. 4, further specify method of the present invention.
Step 41, the dispatcher makes a call, and contains called number in the call information.
Step 42, after GMSC receives dispatcher's calling, initiate MAP (MAP) operation according to called number and send routing information (SRI), and from the response message of the operation that sends routing information, obtain callee's roaming number (MSRN), contain among this MSRN VLR number.
Step 43, from callee's roaming number (MSRN), extract VLR number, with preserve in first database have the number in VLR Visitor Location Register (VLR) number tabulation of corresponding relation to do matching operation with the employed termination number of this dispatcher, judge whether coupling, if the match is successful, execution in step 44 is called out and is continued, otherwise, execution in step 47 call releases.By above-mentioned steps dispatcher's calling is routed to the visit ground mobile switching centre that dispatcher-controlled territory distributes, and restriction dispatcher's calling is routed to the visit ground mobile switching centre that does not comprise dispatcher-controlled territory.
Step 44, after calling was routed to VMSC, VMSC paging train operator (called mobile terminal) obtained the cell id at the current place of train operator;
Step 45 has the number in the cell id tabulation of corresponding relation to do matching operation with what preserve in cell id and VMSC side second database with the employed termination number of this dispatcher, judges whether coupling, if the match is successful, execution in step 46 is called out and is continued, otherwise, execution in step 47 call releases.By this step, allow to connect the calling between dispatcher and the called mobile terminal in its dispatcher-controlled territory sub-district, and restriction dispatcher and the not calling between the called mobile terminal in its dispatcher-controlled territory sub-district.
Step 46 is called out and is continued, and then allows the dispatcher to call out the train operator, sets up conversation between dispatcher and train operator;
Step 47, call release, the restriction dispatcher calls out the train operator.
Technical scheme of the present invention, only need on the call processing software of GMSC/VMSC, do change, do not influence the flow process of call treatment, do not influence the signaling interface between GMSC/VMSC and other network element yet, to the not influence of GSM-R network system, solved the technical problem of calling area restriction simultaneously again effectively.Even in a railway combined mobile communication system of being made up of a plurality of vendor equipments, the supplier of GMSC/VMSC only need upgrade its software also can be for the client provides this calling area limitation function, convenient and easy.
By same processing method, technical scheme of the present invention can be applicable to the calling area restriction in vehicle, the boats and ships wireless dispatchings such as highway, river equally.
Though method of the present invention proposes at the linearly moving object that is scheduled, its method is suitable for too for the object that is scheduled of nonlinear moving.
