ABSTRACT:
Methods and systems are provided for dynamic selection by a mobile station of its home agent using its preferred roaming list (PRL). A mobile station maintains a PRL comprising an association between (i) a first set of data identifying a first wireless wide area network (WWAN) and (ii) a first identifier of a first home agent. The mobile station detects a broadcast of the first set of data by the first WWAN. Responsive to detecting the broadcast of the first set of data by the first WWAN, the mobile station connects to the first WWAN. Responsive to connecting to the first WWAN, the mobile station uses the first identifier to register with the first home agent.
