METHOD AND SYSTEM FOR HYBRID LOCATION AIDING FOR MULTI-MODE DEVICES
First Claim
1. A method of performing a location determination at a mobile communication device, the mobile communication device having a satellite positioning receiver, the method comprising:
- acquiring a first location aiding parameter from a first terrestrial communication network, wherein selection of the first terrestrial communication network is dependent on the first location aiding parameter;
acquiring a second location aiding parameter from a second terrestrial communication network, wherein selection of the second terrestrial communication network is dependent on the second location aiding parameter; and
using the first location aiding parameter and the second location aiding parameter by the satellite positioning receiver to determine the location at the mobile communication device;
wherein the mobile communication device is simultaneously connected to the first terrestrial communication network and the second terrestrial communication network while acquiring the first and second location aiding parameters.

Abstract
A method and system for location determination at a mobile communication device 102 is provided. The mobile communication device 102 includes a satellite positioning receiver 410. The mobile communication device 102 acquires a first location aiding parameter and a second location aiding parameter from a first Terrestrial Communication Network (TCN) 108 and a second TCN 110, respectively. Selection of the first TCN 108 and the second TCN 110 is based on the first and second location aiding parameters, respectively. The satellite positioning receiver 410 uses the first and second location aiding parameters to determine the location at the mobile communication device 102.
