Description

A Realization Method of Trigger Positioning in Mobile Communication System

technical field

The invention relates to a mobile communication network system, in particular to a method for realizing trigger positioning in the mobile communication system.

Background technique

Location-based services (Location Based Services, abbreviated as LBS), also known as mobile location services or positioning services, refers to the mobile network obtains the geographic location information (latitude and longitude coordinates) of mobile terminals through specific positioning technology, and provides them to mobile users themselves, Communication systems or third parties, with the support of certain electronic map information, provide mobile users with location-related, calling or non-calling services. The applications of positioning services can be divided into several types such as location trigger applications, location information applications, tracking applications, and rescue applications.

Figure 1 describes the network structure diagram of the positioning system of the mobile communication network system.

The positioning system includes traditional network entities and newly added entities. The former mainly includes mobile stations, mobile switching centers and home location registers, and the latter mainly includes mobile positioning centers, positioning entities, and positioning service clients.

Mobile Station (abbreviated as MS) is the user terminal equipment of the positioning service. Its main function is to provide measurement information related to the positioning of the mobile terminal, and at the same time complete the application and realization of some positioning services.

The Mobile Position Center (MPC for short) is the core entity for the implementation of positioning services. Its main functions are to control the positioning process, interact with various entities, and store and provide user location information. The mobile location center may also be called a gateway mobile location center (Gateway Mobile Location Center, abbreviated as GMLC).

The function of the positioning entity (Position Determining Entity, abbreviated as PDE) is mainly to process the information sent by the mobile station to the network side, thereby calculating the position of the mobile terminal, and providing auxiliary positioning data for the positioning of the mobile station. The positioning entity may also be called Serving Mobile Location Center (SMLC for short).

Location Service Client (LCS Client for short) is a business application entity, which obtains the user's location through the mobile positioning center, and then provides different location services according to the user's location. This entity is managed by the location service provider.

The mobile station, the mobile positioning center, the positioning entity and the positioning service client are connected through TCP/IP or No. 7 signaling network. The communication between the mobile positioning center, the mobile switching center and the home location register is carried out through the No. 7 signaling network. During physical implementation, two or more entities in the network structure can be combined into one entity.

In terms of positioning services, the current business information and tracking services are mainly the process of positioning through the mobile communication network to query the location of the mobile phone or the mobile phone actively reports the location. This type of positioning method is widely used.

Location-triggered applications are automatically triggered when a user enters a predetermined area. The business side monitors certain specific areas through positioning entities and learns about users in specific monitoring areas in real time. This type of triggered location application has high application value , can be applied on a large scale in the following application areas:

(1) Location advertisement service. This service is based on the fact that information receivers receive the information they are most concerned about based on their own location. The information sender can also select the most suitable group of people to receive. After a certain area, commercial advertisements in this area can be delivered to users. Users can set which areas and types of advertisements to receive.

(2) Make friends by location. Through the triggered location service, you can know the current specific location of your friends in real time, and make friends and chat through the location, making the chat application more dynamic.

(3) Public security monitoring. During the process of handling a case, public security personnel can query users in a designated area to monitor the designated area. For example, when investigating a case, you want to know who enters and exits a certain place (criminal trading place), how long they stay, etc.

This type of application needs to be automatically triggered when the user enters a predetermined area. From a business perspective, the triggered location application has the following characteristics:

Real-time: Due to the business principle of advertising and regional monitoring of nearby consumption, it is generally necessary to be able to notify users who arrive at a designated location in real time.

Low accuracy requirements: Since advertisements, making friends, and regional monitoring are generally aimed at a large predetermined area, the accuracy requirements are low, and the positioning accuracy based on CELLID (community identification) can meet the requirements.

From the perspective of implementation, the traditional network-based positioning method is to actively query the user's location based on the user ID. If a trigger-based location application is implemented, it can only be continuously searched for all users by means of polling. Positioning, after obtaining the location information of all users, and then filtering according to the user's location according to the business needs.

FIG. 2 shows a schematic diagram of a traditional positioning process, and a flow chart of positioning based on a control plane in a CDMA network. For details, see the following process description:

201: The LCS client computer sends an ISPOSREQ (intersystem location request) to the Mobile Positioning Center (MPC) of the target mobile phone;

202: The MPC authenticates the LCS client and passes it, and the MPC sends LPREQ (LCS parameter request/location service parameter request) to the home location register (HLR) of the mobile phone;

203: The HLR determines that the target mobile phone is currently in an active state, and the HLR returns lpreq (LCS parameter request response/location service parameter response) to the mobile positioning center, and the 1preq message includes the MSC identifier where the user is currently located;

204: The MPC sends an ISPOSREQ message (intersystem location request) to the serving mobile switching center (MSC) to obtain the current wireless environment information of the target mobile phone;

205: The serving MSC includes the current wireless environment information of the target mobile phone in the isposreq response message (intersystem location request response) and returns it to the MPC;

206: The MPC performs IS801 message interaction with the PDE and the MS according to the MS's support for IS801 and the currently requested service quality and other parameters. The current geographic location information is returned to the MPC;

207: The MPC includes the location information of the mobile phone or the cause of the location failure in isposreq (intersystem location request response) and returns it to the requesting LCS client;

From the above process, it can be seen that the traditional positioning process is to actively query the current location of the user through the positioning system. If you want to automatically trigger the user in a specific area through this method, you need to continuously poll the user's position to obtain the user's current location in a specific area. Regional user list, this method is not flexible enough to meet business needs, and cannot satisfy real-time requirements. It is necessary to traverse and query users within a certain group range, which also has a great load impact on the existing system.

Contents of the invention

The purpose of the present invention is to solve the problems existing in the prior art, such as inflexible business, unsatisfactory real-time performance, load impact on the existing system, etc., and proposes a method for realizing trigger positioning based on cells.

In order to achieve the purpose of the above invention, the present invention proposes a method for realizing trigger positioning in a mobile communication system. In the mobile communication network, the mobile terminal will continuously initiate events such as location update, call, and short message sending and receiving. Traditional network entities (including mobile switching centers/visitor location registers/base station controllers) will receive the above events initiated by the mobile station. After triggering the message, the mobile station ID and the current wireless cell parameters of the mobile station in the parsed message are encapsulated in a cell location report to the positioning system. Through this real-time trigger, the positioning system can immediately know the user's current cell location information, and immediately Actively push to service providers.

A method for implementing trigger-based positioning in a mobile communication system proposed by the present invention is specifically implemented as follows:

(1) The positioning business client sets the positioning query rules to place an order to the positioning system according to the business needs, and the positioning system calculates and records the relevant ordering information of the positioning service client's ordered position through the positioning query rules;

(2) The mobile station initiates a message containing the information of the wireless cell where the mobile station is currently located;

(3) After the traditional network entity receives the above-mentioned message initiated by the mobile station, it encapsulates information such as the resolved user ID and wireless cell parameters in a location report message and sends it to the positioning system;

(4) The positioning system calculates the position according to the wireless cell information in the position report message, and after processing, sends the relevant position information of the specified user and the predetermined rule ordered to the appropriate positioning service client according to the predetermined rule.

In the step (1), the location ordering can be carried out based on message interaction or calling the setting interface provided by the positioning system;

In the step (1), the service can be set to require all users near a certain latitude and longitude, or all users near a certain base station cell;

In the step (1), the positioning system calculates the relevant ordering information of the positioning client ordering position through the positioning query rules, which can be calculated and recorded by the positioning system through the longitude and latitude of the positioning client business order and the search radius in the query rules and records the relevant ordering information of the position. Base station ID.

In the described step (2), the mobile station origination message refers to the message that the mobile station accesses the traditional network. This type of message includes the following messages: a location update message, a call-initiation message, a call-out access message, and a short message call-initiation message. Access message, short message terminal call access message, handover message, etc.;

In the step (3), the wireless cell parameter is a system identification number, a network identification number, a base station identification number, a cell identification number, a mobile exchange identification number, or a network name.

In the step (3), after receiving the message initiated by the mobile station and including the information related to the wireless cell where the mobile station is currently located, the traditional network entity can make a corresponding judgment, and when the wireless cell information of the mobile station changes, then Encapsulate information such as user identification and wireless cell parameters that have undergone cell changes in a location report message and send it to the positioning system to reduce the corresponding network load.

In the step (3), after the traditional network entity receives the message about the wireless cell where the mobile station is currently located, the traditional network entity may not make any judgments, and directly send all the user information in the received related messages. Information such as identification and wireless cell parameters are encapsulated in a location report message and sent to the positioning system.

In the step (3), the location report message may be carried based on SS7 or carried by TCP/IP.

In the step (4), the user-related location information includes the user identification and the latitude and longitude of the user's current location.

In the step (4), the positioning system can filter the user-related information that has been frequently sent per unit time according to the requirements of specific services, so as to reduce the corresponding network load.

The traditional network entity notifies the positioning system side of the change of the parameters of the wireless cell of the user when the mobile station executes a message related to cell information.

The traditional network-based positioning method is a positioning system that inquires the user's location through the network based on the user ID. If this method is used to implement the triggered location service, it is necessary to continuously poll all users and monitor all users. Positioning to detect users corresponding to a target area. When this method is implemented, the system consumes a lot. In the process of polling, positioning cannot reflect all the arrival positions of users in real time, and cannot obtain the information of all users in a certain area in real time. latest information.

The implementation method of triggered positioning in the mobile communication system proposed by the present invention is a new technical solution independent of traditional positioning, and is suitable for realizing triggered positioning services. This technical solution has high real-time performance and less burden on the system.

After the positioning system obtains the user's position, it provides different positions according to the user's position and query rules. business client. This entity is managed by the location service provider.

The traditional network entity described in the present invention implements the following functions: it includes a mobile switching center, or a visitor location register, or a base station controller. In the triggered positioning system, the positioning system is generally only connected to a traditional network entity, because in this model, the mobile switching center, or the visitor location register, or the base station controller can obtain the information required for the triggered positioning service. related messages, which include the user's identity and the information of the cell where the user is currently located.

The technical basis for proposing a triggering positioning process is as follows: In a mobile communication network, a mobile station will continuously update its location based on periodicity and location area, and the location update message contains the information of the wireless cell where the mobile station is currently located, and When the mobile station initiates, receives, and switches services, it will report the wireless cell, so that the mobile switching center/visitor location register/base station controller will continuously obtain the latest cell information of the user, and the location validity of the cell information is general. Around 10-15 minutes. During the continuous position change of the mobile station, if the positioning system acquires the change, it can be directly triggered to the application. This implementation method is real-time and convenient.
