Abstract
The position of a mobile terminal is determined including receiving location determination signals from satellite positioning system transmitters. Location assistance information is received from a wide area wireless communication network in an associated format defined by a protocol of the network. Location assistance information is received from a local wireless transmitter in the associated format. The local wireless transmitter and the wide area wireless communication network are uncoordinated and have different associated wireless transmission protocols. The position of the mobile terminal is determined based on the received signals from the satellite positioning system transmitters and location assistance information received from either the wide area wireless communication network or the local wireless transmitter. The source of the location assistance information may be selected based on availability and may be an ad hoc protocol wireless transmitter, such as a Bluetooth transmitter.
