Abstract:
1. A wireless communication method, the method comprising: obtaining, over a backhaul tunnel established between a first access network associated with a first coverage area supporting a first radio access technology (RAT) and a second access network associated with a second coverage area supporting a second RAT that is different from the first RAT, pre-registration session information that includes network parameters used to establish a pre-registered session with the second access network associated with the second coverage area if an access terminal in the first coverage area supporting the first RAT receives a border signal from an access network in the first coverage area supporting the first RAT, the border signal indicating that the access terminal has moved into a portion of the first coverage area defined as a pre-registration zone for the second coverage area supporting the second RAT and pre-registration session information associated with the second coverage area is unavailable in the access terminal, the second coverage area bordering the first coverage area; starting a pre-registration session information timer associated with the obtained pre-registration session information; and storing the obtained pre-registration session information until the pre-registration information timer associated with the obtained pre-registration information expires.
