Abstract
Methods and systems are provided for use of positioning information to determine whether to trigger a packet-data-network re-registration when detecting multiple radio signals of sufficient strength. A mobile node registers with a first mobility agent, wherein the mobile node communicates with the first mobility agent via a first radio transceiver. The mobile node determines that a first signal strength of a first radio signal from the first radio transceiver and a second signal strength of a second radio signal from a second radio transceiver are each greater than a first threshold and that the second signal strength is greater than the first signal strength, and responsively determines whether or not it is traveling. If the mobile node determines that it is traveling, the mobile node registers with a second mobility agent, wherein the mobile node communicates with the second mobility agent via the second radio transceiver.
