Embodiment Construction

[0024] Three specific implementations of the present invention will be described below in conjunction with the accompanying drawings. All three implementation modes need to configure routing data between the CDMA mobile positioning center and the G&C gateway. This content will not be repeated in the following introduction.

[0025] One of the implementation methods:

[0026] refer to figure 1 , the GSM user has successfully connected to the CDMA network, and needs to trigger the third-party positioning service for it:

[0027] 101) The CDMA MPC queries the location information of the GSM user to the corresponding G&C gateway;

[0028] 102) The G&C gateway returns the location information of the GSM user in the CDMA network to the CDMA MPC, that is, the CDMA MSC visited by the user;

[0029] 103) The CDMA MPC sends the trigger positioning short message MT to the CDMA MSC according to the location information returned by the G&C gateway, and then the CDMA MSC sends it to the...

Abstract

The invention relates to method of CDMA network for providing third party positioning for GSM mobile user, who enters into CDMA network. The method includes following steps: configuring route data between CDMA MPC and G&C gateway in order to obtain position information of GSM user from G&C gateway; CDMA MPC regards G&C gateway as CDMA HLR, queries position information of GSM user to G&C gateway; based on returned position information from G&C gateway, CDMA MPC triggers sending positioning short message MT to GSM user, who roams to CDMA network; GSM user roamed to CDMA network sends short message MO of agreeing positioning through CDMA MSC to CDMA MPC. The invention provides third party positioning service only processing flow of G&C gateway is needed to modify.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a technique for positioning a GSM mobile user entering a CDMA network. Background technique [0002] In order to realize the mutual roaming between the GSM network and the CDMA network, it is necessary to add a device between the CDMA network and the GSM network to be responsible for the conversion of signaling, parameters and services of the two networks. This device is called IIF (Interworking and Interoperation Function) in the standard of 3GPP2 (Third Generation Partnership Project 2, third-generation mobile communication standardization partner project 2), and is called G&C in China Unicom's technical specifications The gateway (GSM&CDMA gateway), for the sake of simplicity of description, is collectively referred to as the G&C gateway in the present invention. The G&C gateway is an existing technology, and for details, refer to the N.S0028 protocol of 3GPP2. [0003] I...
