ABSTRACT:
A first access point name associated with an access gateway node involved in a data session of a mobile station over a first type of wireless network is received. In response to handoff of the mobile station from the first type of wireless network to a second, different type of wireless network, the first access point name is transmitted to enable continued use of the access gateway node for the data session of the mobile station over the second type of wireless network.
