Abstract
A wireless network of a first type receives a request for network entry from a mobile station. A service continuity query is sent to a service node. A service continuity response is received from the service node. The service continuity response includes a network access identifier. The network access identifier is determined to be associated with an existing session on a wireless network of a second type. The existing session is using a mobile internet protocol address. On the wireless network of the first type, a session is assigned the mobile internet protocol address.
