Patent ID: 8611926

Claim:
A method for requesting network-derived location-specific correction data for a mobile geographic position aware receiver, said method comprising: communicatively coupling a mobile geographic position aware receiver having a first Internet Protocol (IP) address with a first port on a router; communicatively coupling a wireless transceiver with a second port on said router; communicatively coupling a wireless communication device with a third port on said router, wherein said wireless communication device and said wireless transceiver employ differing wireless communication protocols; and communicatively coupling a processor with said router said processor for executing a communications access command sequence comprising: testing for a wireless network connectivity of said wireless communication device; in response to determining via said testing that said wireless connectivity exists, contacting a correction data source using said wireless communication device to acquire a set of network derived location-specific correction data based on an approximate current location of said mobile geographic position aware receiver; and in response to determining via said testing that said wireless connectivity does not exist, generating a data message to be sent via said wireless transceiver, said data message comprising an IP address of said router, said approximate current location of said mobile geographic position aware receiver, and a request for network-derived location-specific correction data.
