In the CDMA mobile communication network, the conventional positioning service implementations are: adding two new network entity in a network: a mobile positioning center (MPC) and the position determining entity (PDE). Meanwhile, any original network entity, a home location register (HLR) to upgrade, and it has a data storage capacity of the user location information transmitting user location. In the positioning process, the first network to the requesting user's home location MPC, then MPC acquire the home MPC address of the service by the user of the roaming home location register, the service position again requesting user MPC. MPC while obtaining user location information service, the mobile switching center where the user needs to request the user's wireless information, and then interact with the positioning entity, to calculate the position of the user by the positioning entity.

This implementation has the following disadvantages:

First, the need to distinguish between ownership and service MPC MPC implementing. Meanwhile, it is necessary to record the user address of the user of the service registration MPC on the home location register. Each time positioning requires signaling conversion between two MPC. Positioning process is relatively complex, high demands on the signaling network, the large signaling traffic.

Second, the need for the home location register of the location services dedicated special treatment, users need to provide services and stores the address of the MPC. When upgrading from common network to support the positioning of the network, the need for existing devices - upgrade the home location register, the high cost of the upgrade, the risk is relatively large.

Third, the location services application service information needs of users while in the home MPC and HLR which is not easy to modify user information stored synchronization, error-prone. SUMMARY

The present invention is to overcome the technical task CDMA positioning system positioning process complicated and requires special handling a home location register, and the disadvantage of the user information synchronization difficulties, a new way to implement location services in a communication system.

The method of the present invention is implemented in location service, mainly implemented in the mobile location center, the mobile switching center and the positioning entity play a supporting role.

In the movement positioning process, the mobile positioning center overall control functions.

Mobile positioning center is responsible for storing and managing the user about the positioning of business information, including subscription information, authentication information such as location information and restrictions, users. The home location register no longer stored subscription information related to the user location.

The technical solutions of the present invention is as follows:

Mobile positioning center by SS7 network or TCP / IP network requests other entities receiving position, controls positioning of the user, and returns the acquired location information to a requesting entity;

Acquiring location information of the user process, the mobile positioning center directly requested short message address of the user currently requesting the switch to the roaming home location register;

After obtaining information about roaming mobile location center acquiring the positioning information from the entity roaming own database, and the interaction of the roaming switching center and the positioning entity, the mobile positioning center obtains the current position of the user directly.

With the present invention implemented method of positioning service, as compared with the original system, the process is greatly simplified, eliminating the difference between the home MPC MPC and the service, subscriber information is managed entirely by the home MPC, the original home location register does not special request.

BRIEF DESCRIPTION
