  • Efficient use of assistance data services in dual/multi-SIM terminals
    Patent number: 8538418
    Abstract: Method, apparatus, and computer program product example embodiments of the invention are disclosed for providing flexibly in selecting sources for Assisted Global Navigation Satellite Systems (A-GNSS) services. Example embodiments include at least two SIM modules in a wireless communications device to enable accessing at least two different wireless carriers to obtain at least two different sets of A-GNSS capability information. Optimal A-GNSS features are selected from the A-GNSS capability information from the at least two different wireless carriers and combined into a composite set of optimal A-GNSS features. Example embodiments of the invention may include a wireless communications device having at least two SIM modules sharing one or more RF modems.
