Abstract (en)
[origin: WO0034800A1] A method of provisioning differential GPS (DGPS) assistance data (58, 59) over a WCDMA wireless communication network (10) to facilitate positioning of mobile communication devices (12, 20). The method comprises providing differential GPS assistance data over a dedicated physical data channel (DPDCH) and/or a dedicated physical control channel (DPCCH). The mobile communication terminal has an integrated GPS receiver and can comprise of cellular or PCS telephony handsets, a mobile computer, PDAs, etc. The present invention facilitates a mechanism for providing the DGPS assistance data to achieve positioning of the mobile communication device accuracy down to about 5 meters.
