Description of drawings
Fig. 1 is the network structure that group system that the present invention describes combines with navigation system;
Fig. 2 is the flow chart that utilizes location technology that the object that is scheduled is positioned that the present invention describes.
Embodiment
As shown in Figure 1, the communication system network structure of correspondence of the present invention mainly is made of following several systems: trunked call control system, Trunked Radio System, positioning service system, base station system, GIS-Geographic Information System.Can be interconnected between each system by Signaling System Number 7 net or Packet Data Network.
Wherein:
(1) trunked call control system is by dispatching control center DCC (Dispatching Control Center) and dispatching home location register DHR (Dispatching Home Register).DCC is the control centre of trunked call, is responsible for the functions such as call manager, call management, accounting management of trunked call (group calling, secret are exhaled, organized temporarily, broadcasting etc.).DHR is the cluster user database, record clustering user position information, customer service attribute information.
(2) Trunked Radio System is by scheduling proxy server (DAS, Dispatch Agent Server), dispatching desk.DAS is the acting server of dispatching desk, functions such as the access control of responsible dispatching desk, call control agent, positioning service service broker.Dispatching desk possesses scheduling feature, for the user provides visual scheduling man-machine interface, possesses the function of positioning service client simultaneously again, presents functions such as cartographic information for the user.
(3) positioning service system, according to the difference of various location technologies, the composition of navigation system also has nothing in common with each other.Major function is to accept the location service request of dispatching patcher, obtains the positional information (longitude, latitude coordinate etc.) that is requested cluster user by location technology, and positional information replied by location-based service sends to dispatching patcher.It is to be noted, the present invention is for the not specific requirement of location technology of positioning service system itself, can be any location technology, such as based on the location technology of Cell-ID, based on the location technology of AFLT, based on the location technology of GPS, based on technology of gpsOne or the like.
(4) base station system is made up of base station transceiver BTS (Base Transceiver System) and base station controller BSC (Base Station Controller).Base station transceiver is finished functions such as the modulation and demodulation, radiofrequency signal transmitting-receiving of baseband signal, and base station controller is then finished all kinds of switchings of wireless resource allocation, call treatment, power control and support terminal.Base station sub-system BSS links to each other with scheduler subsystem, switching subsystem by standard interface, satisfies the miscellaneous service demand of colony terminal, comprises group service, telephone service and data service.
(5) GIS-Geographic Information System provides GIS service.Receive the GIS service request of service requester, by GIS engine queries map data base, obtain geographic information datas such as geographical text description, near terrestrial object information, and the GIS service response is sent to service requester according to positional information (longitude, latitude etc.).
Selectable, can also comprise mobile switch system in the present networks mechanism, generally there are mobile switching center MSC/VLR (Mobile Switch Center/Visited Location Register) and attaching position register HLR (Home Location Register) to constitute, for the user provides mobile exchange capacity and the function that interconnects.Mobile switching centre and dispatching control center are independent on function, physically partable.Because mobile switch system is not indispensable system in this communication system, so clearly do not mark in present network architecture.
Fig. 2 is the example that utilizes location technology that the object that is scheduled is positioned, and concrete steps are as follows:
(201) dispatching desk sends Location Request to scheduler object to DAS, the sign that comprises scheduler object in the request is as IMSI (International Mobile SubscriberIdentification), OID (Organization ID) of the MDN of group (Mobile Dictionary Number), the VPN of group (Virtual PrivateNetwork) number, the GID of group (Group ID), cluster user MDN, cluster user VPN number, cluster user or the like;
(202) DAS obtains corresponding cluster user tabulation according to the scheduler object sign, and the sign of cluster user, comprises IMSI, MDN, ESN, VPN number etc.The mode of obtaining cluster user tabulation is relevant according to specific implementation, and such as for un-activation group, DAS sends query requests to DHR, and the DHR query subscriber database returns to DAS to Query Result; For the calling that activates, DAS can obtain from this locality to call out corresponding cluster user tabulation, also can send query requests to DCC, and DCC returns to DAS and calls out corresponding cluster user tabulation;
(203) DAS sends the positioning service request to navigation system, comprises in the request that the cluster user that is positioned is tabulated and each user's sign;
(204) positioning service system obtains each user position information through a series of location technology operations, comprises longitude, latitude information, sends response message then to DAS;
(205) DAS receives replying of positioning service system, extracts user position information, sends the GIS service request to the GIS service system then, comprises the Control Parameter such as coordinate, ratio of map in the request.Optionally, can also comprise the cluster user tabulation in the request, and each user's information such as longitude and latitude;
(206) the GIS service system is received the GIS service request of DAS, by GIS engine queries map data base, constructs geography information, and sends to DAS by the GIS service response;
(207) DAS receives the GIS service response, sends to dispatching desk the location of scheduler object is replied, and comprises positional information of geography information, cluster user tabulation and each group member or the like in replying;
(208) dispatching desk receives that the group location of DAS replys, and generates interface, scheduler object location, and performance geography information and cluster user optionally, can also show group user sign or the like;
Need to prove, the group that the scheduler object here can a fixed member, can be a group by interim member composition, may diminish to single cluster user, also can be greatly to a group.
Based on above implementation step, dispatching desk timing and DAS finish the positioning action to scheduler object alternately, thereby reach the effect to the real-time locating and monitoring of scheduler object.
In addition, different scheduler objects can have the different form of expression (as difformity, different colours) at dispatching desk, can be that the dispatcher locatees a plurality of scheduler objects simultaneously at interface, same location like this.
