The embodiments of the present invention are described in detail below by way of specific examples, but the examples are not intended to limit the scope of the invention.

As shown in FIG. 2, a network structure diagram for implementing a positioning function for an existing trunking communication system, the network architecture diagram includes: a cluster scheduling subsystem, a base station subsystem, a switching subsystem, and a positioning subsystem. Each subsystem is interconnected by a SS7 network or a packet data network.

(1) The cluster scheduling subsystem includes a PTT Dispatching Server (PDS), a PTT Home Register (PHR), a dispatcher server, and a dispatcher client.

(2) The positioning subsystem is composed of network elements such as a mobile positioning center and a positioning entity.

(3) The base station subsystem generally includes a base station controller, a base station (BTS), and a mobile switching center. FIG. 3 is a network architecture diagram of implementing positioning in a cluster system according to an embodiment of the present invention, where the network architecture includes:

(1) The cluster scheduling subsystem has the same composition as the existing cluster scheduling subsystem and will not be described again.

(2) a short message subsystem, including a location agent (LA) unit and a short message service center (SMS);

The short message service center is responsible for relaying, storing or forwarding short messages. The protocol from the terminal to the short message service center can transmit short messages from the terminal or to the terminal.

The positioning agent unit is a core functional entity for processing positioning and short message receiving and dispatching in the digital trunking communication system, and is connected to the dispatching station server in the scheduling subsystem, and is responsible for processing the positioning and sending request in the cluster communication; and simultaneously connected with the short message service center , forwards short message delivery requests from the cluster system. A standard positioning protocol L1 interface is used between the positioning agent and the dispatcher server, and a standard short message point-to-point protocol is adopted between the positioning agent and the short message service center. It should be noted that the positioning proxy unit can be implemented as a separate functional entity or as a functional module of an entity in the digital cluster system. The SP is connected to the dispatcher server.

(3) The base station subsystem is the same as the existing base station subsystem and will not be described here.

Comparing the network architectures shown in FIG. 2 and FIG. 3, the network architecture diagram provided by the embodiment of the present invention has fewer positioning subsystems and more SMS subsystems;

Referring to FIG. 3, the method for realizing positioning by using a short message in the cluster system provided in this example, as shown in FIG. 4, includes:

Step 401: The DAC sends a request to the DAS to continuously locate a group in the trunk call.

The location request includes an identifier of the group to be located, for example, a group mobile directory number (GMDN), and a group virtual private network (VPN). Step 402: The DAS obtains a group member list according to the cluster call group identifier, and determines, according to the identifier of the group member, whether the DAC can initiate a location request permission. For the inactive group call, the DAS sends a query to the cluster system user data through the PHR. request.

For the activated group call, the DAS can obtain the group member information corresponding to the call locally.

The identifier of the group member may be an international mobile subscriber identity (IMSI), an MDN (Mobile Directory Number), an electronic serial number (ESN), or the like.

Step 403: The cluster system user database queries the user database, and returns the query result to the D AS through the PHR.

The query result includes: identifier information of the group member, including IMSI, MDN, and the like. Step 404: The DAS determines that the DAC initiates a continuous positioning request, and sends a Location Trigger Request (LTR) message to the LA according to the L1 interface specification, where the request message includes the MDN list of the terminal to be located, and the request to start and end the positioning. The time interval between the time and the reported position.

Step 405: The LA receives the request, and after decoding the request, after determining that the LTR message is received, the LA immediately replies with a Location Trigger Answer (LTA) message.

The response message does not carry the terminal location data, but actively pushes the Location Trigger Request Report (LTRR) message to the DAS by using the L1 interface when the terminal periodically uploads the location data at the required time interval. , to inform the location of the terminal to be located;

Step 406: The LA constructs a short message sending request by using the MDN in the MDN list according to the short message standard interface requirement, and sends the short message sending request to the short message service center, where the short message sending request includes a positioning verification code, where the full certificate code is used for the short message and Ordinary short messages make a difference.

Wherein, the positioning is an L1 interface, and the L1 interface is based on a hypertext transfer protocol (Hypertext) Transfer Protocol, HTTP) Protocol, the protocol content is defined by Extensible Markup Language (XML). The standard short message interface can also support multiple protocols, such as the popular Short Message Peer to Peer (SMPP) protocol and the Short Message Gateway Interface Protocol (SGIP).

Among them, LA will save the location information of the dispatcher server, including the sender MDN, the IP address and port of the dispatcher server.

Step 407: The short message service center delivers the short message to the terminal to be located corresponding to the MDN according to the short message sending request.

Step 408: After receiving the short message, the terminal to be located reads the verification code from the content according to the Global Position System (GPS) information format. If the verification code is not empty, it determines that the short message is The GPS locates the short message, and the GPS module of the terminal communicates with the GPS satellite to obtain the location information, and then encapsulates it into a short message sending request response to the short message service center, and the response is a short message;

Step 409: The short message service center receives the response and sends it to the location agent.

Step 410: After the positioning agent receives the short message and decodes it, it finds that it is a continuous positioning response message, and encapsulates it into an LTRR (Location Trigger Request Report) request according to the L1 interface, and finds that it needs to be sent to the IP according to the MDN. After the address and port are sent to the port corresponding to the dispatcher server corresponding to the IP address;

Step 411: After receiving the location proxy location response request, the dispatcher server sends the location proxy response request to the scheduler client. After receiving the response from the dispatcher server, the dispatcher client removes the location information and displays it on the interface.

Step 412: The dispatching station server sends an LTRR response to the positioning proxy. After receiving the response, the positioning proxy does not need to do any processing, but only indicates that the request has been successfully sent;

Step 413: The terminal sends the positioning according to the period value saved in step 408, after the period is reached. The short message is repeated from step 409 to step 412 until the location request cancellation notification message is received. The above example is a continuous positioning request. The single positioning is similar to the continuous positioning. The difference is that the step 404 is not sent to the positioning request. Instead, the location immediate request (LIR) message, after receiving the LIR message, the positioning agent does not immediately send a response to the DAS, but waits until the terminal returns to locate the short message, and then responds to the location immediately. LIA ), the terminal will not periodically locate the SMS.
