I am actually not clear on real network deployments of GSM n/w.
Basically on my MS i have a feature supported by Operator where in i will come to know which part of city ( or location ) i am presently located.
I think this information is as part of hand-shake mechanism, where in the Location Information, will be used to know where am i.
If i am not wrong this “location information” is nothing but information about the BTS, serving my MS currently.
Basically i am planning for a service wherein i can come to know the location information about other MS’s?.
If i am not wrong, the requested MS which wants to know other MS’s location, should be able to make a USSD request to USSD server and get in response from USSD Server the location information.
Can any of you please help me to know, how can i do this.
Presently what i have in mind is, as part of USSD request, user will mention the MS’s MSISDN ( mobile number), using which my HPLMN USSD Server will forward the request to respective USSD Server in to the “User specified MSISDN’s” USSD Server, which will put a MAP ( Not sure on this interface ) request and get in response the Location Information of the MS, whose location information was requested.
This respose will be forwarded back to the MS, which requested the “Location information”.
Let me know, if any of you have any other ideas.
Thanks for your inputs.
