Abstract
A telecommunications system and method is disclosed for downloading encrypted network information, such as Base Transceiver Station (BTS) coordinates, in a point-to-point manner between the network and a Mobile Station (MS) with location calculation capabilities. When an MS registers with the network, the MS shall indicate as part of the 'early classmark' process its location calculation capabilities and the type algorithm to be used for deciphering the network information. As a result of a mobile originating request for assistance data, the network shall encrypt and download the network information to the MS. The MS deciphers the network information in order to position itself.
