US Patent 8712378 Authorization method for location based services

A MLP request message is transmitted through a wireless mobile communication network, from a mobile station to a SUPL server. The MLP request message contains credential information for an AGPS application running on the mobile station. After the MLP request message has been transmitted, a MLP response message is transmitted through the network from the SUPL server to the mobile station. The MLP response message is responsive to the credential information and indicates whether the SUPL server has authorized the AGPS application. If the AGPS application is authorized, communication between the AGPS application and the SUPL server, through the network, implements a function of the AGPS application.
