I have been working on Location Based services for Mobile phone.
To make it universal, dont want to use GPS or Satellite for Tracking/Locating information. I have been working with GPRS to track the location of the mobile user.
There is a Protocol called GTP (GPRS Tunneling Protocol). This is used to communicate between GGSN and SGSN.
My question is how to retrieve the GTP Header and then locate the Location Information?
