3) carry out pseudo-number translated to DSMP (Data Service Management Platform, Service Provisioning Administration Core Environment) request after the LSP request of receiving;

4) DSMP returns user's pseudo-code to LSP;

5) LSP initiates LBS service request (on pseudo-number information of the user of China Mobile) to SP;

6) SP receives that the request back is to LSP initiation LBS service request (identifying the user of China Mobile through pseudo-number here);

7) after LSP receives the request of SP; Send the request of number translated to DSMP; Pseudo-number translated is become corresponding M SISDN, and ((ISDN promptly is an integrated services digital network to Mobile Subscriber International ISDN/PSTN number; Be the abbreviation of Integrated Service Digital Network); MSISDN is meant that the calling subscriber is a number of calling out required group an of mobile subscriber among GSM (global system for mobile telecommunications communication system) PLMN (public-land mobile network), and effect is same as fixed network PSTN number; Be in the numbering plan of public telephone network switching network, the unique number that can discern the mobile subscriber);

8) LSP inserts ground DSMP to SP and initiates the authentication request to the SP conventional data, according to calling subscriber's MSISDN, sends the conventional data authentication request to the DSMP of user attaching again, if success then carried out for the 9th step; If it is unsuccessful then return failed authentication;

9) LSP carries out the authentication (whether decision according to circumstances needs the user to get involved) of SP, calling subscriber's performance data.If the LSP that SP inserts is not the LSP that the calling subscriber belongs to, need to accomplish authentication to the user personality data through the interconnecting interface between the LSP;

10) LSP initiates Location Request to the GSM network;

11) the GSM network obtains China Mobile's user position information through certain location technology, and returns to LSP;

12) after LSP obtains China Mobile's user position information, initiate the cartographic information conversion request to GIS (Geographic Information System, GIS-Geographic Information System) according to the type of SP service request;

13) GIS returns corresponding cartographic information transitional information and gives LSP;

14) LSP returns corresponding LBS service request and responds to SP (transmitting pseudo-number);

15) SP returns corresponding user LBS service request and responds to LSP (comprising pseudo-number information);

16) after LSP received the request of SP, the request to DSMP sends number translated became corresponding M SISDN with pseudo-number translated;

17) LSP returns corresponding user LBS service request and responds to each IAD;

18) each IAD returns corresponding user LBS service request and responds the user to China Mobile.

The CELLID location technology has the deficiency of several aspects:

1, need operator or SP to participate in;

2, need certain traffic fee or operating cost;

3, need through WAP (Wireless Application Protocol, WAP)/SMS (Short Message Service, SMS (Short Message Service) is a kind of storage and transmit service) and network interaction positional information, the time is long;
