Description

A method and device for supporting location services to access a mobile positioning center

technical field

The invention relates to the field of mobile communication, in particular to a method and equipment capable of supporting unified access of location services to a CDMA mobile positioning center and a GSM mobile positioning center.

Background technique

The development of mobile communication to this day, the place that best reflects its vitality lies in its rich and colorful value-added services. Under this development opportunity, the location service has quietly emerged as a new value-added service provided by the mobile communication network. The location service can obtain the user's location information through the positioning technology of the wireless network, and provide it to the user himself, the communication system itself, or an authorized third party, so as to realize various humanized services by using the user's location information.

According to the specifications of 3GPP and 3GPP2, the mobile positioning center (MPC, Mobile Position Center) or the gateway mobile positioning center (GMLC, Gateway Mobile Location Center) provides the location information of the mobile station to the service provider (SP, Service Provider). SP combines related images, text and other content to complete value-added services related to this location, and provide location-based services, or location services, to end users.

At present, there are GSM network and CDMA network in the existing network. In the existing location service system, the location service system of the GSM network and the location service system of the CDMA network are two independent and divided systems. As shown in Figure 1, in the prior art, according to the enterprise specifications of China United Communications Co., Ltd. (China Unicom), the location service in CDMA uses the SPACCESS protocol to access the location service access device, and the location service access device uses the L1 protocol to connect Access to the mobile positioning center of the CDMA network to complete the functions of SP authentication, authentication, billing and so on. The API1 protocol is adopted between the location service in the GSM network and the mobile positioning center.

In this case, the location service in the GSM network cannot access the mobile positioning center of the GSM network through the location service access device in the CDMA network. The location service in the GSM network cannot access the CDMA mobile positioning center, so it cannot locate the CDMA network users, so it cannot serve the CDMA network users. The location service in the CDMA network cannot serve GSM network users either. Due to the differences in interface protocols, the location service cannot be conveniently applied to the CDMA network and the GSM network at the same time. If the GSM network and the CDMA network are developed separately, the development cost of the SP will be increased, and the location-based value-added services in the two networks will be limited. shared. It is also not conducive to the unified management, operation and billing of location service access devices.

Detailed ways

The purpose of the present invention is to provide a method and a location service access device, so that location services using the SPACCESS protocol, API1 protocol, or other similar protocols can be connected to the device, and the authentication, authentication and accounting of the device can be used. Fees and other functions, and then initiate a positioning request to the CDMA mobile positioning center supporting the L1 protocol, or to the GSM mobile positioning center supporting API1, or to the mobile positioning center supporting other similar protocols.

Method of the present invention comprises the following steps:

1. In the location service access device, pre-configure the following data:

a) Access protocols available for location services.

b) The TCP port number used by various access protocols, or the signature label that can uniquely indicate the protocol type.

c) information such as the name, IP address, and port number of the accessible mobile positioning center.

d) Correspondence between target users and mobile positioning centers, such as some GSM network users corresponding to a certain GSM positioning center, another part of GSM network users corresponding to another GSM positioning center, and CDMA network users corresponding to a CDMA positioning center.

e) The access protocol used by each mobile positioning center.

2. The location service sends a location request message to the location service access device, requesting location information of one or more target users. Messages may follow the SPACCESS protocol, the API1 protocol, or other similar protocols. The message contains the identification of the target user, such as a mobile phone number;

3. The location service access device analyzes the request message, and judges and records the protocol type of the request message in combination with the pre-configured data (a) and (b);

4. The location service access device reads the located target user identifier in the request message;

5. The location service access device determines the target user type according to the located user identifier, and combines the preconfigured data (c),

(d), select the mobile positioning center;

6. The location service access device constructs a location request message conforming to the corresponding protocol according to the selected mobile location center and combined with the pre-configured data (e);

7. The location service access device sends a location request message to the selected mobile location center;

8. If multiple target users in the location service request correspond to different mobile positioning centers, repeat steps 5 to 7;

9. The location service access device receives the location response message from the mobile positioning center;

10. If there is step 8, you need to repeat step 9;

The location service access device converts the response message of the mobile positioning center according to the protocol type of the location service request recorded in step 3, and returns it to the location service.

Using the method of the invention, no matter the location service in the GSM network or the location service in the CDMA network, no matter whether the location service adopts the SPACCESS protocol or the API1 protocol, it can be connected to the location service access device. The location service access device constructs a request message acceptable to the mobile positioning center according to the mobile positioning center corresponding to the located target user, and requests the mobile positioning center for location information.
