Abstract:
1. A method for allowing handoffs for wireless mobile nodes using pre-paid mobile services on a mobile network, comprising: receiving a first request message on a first non-mobile service network device on a mobile network from a wireless mobile node to establish a communications session for the wireless mobile node; sending an update message from the first non-mobile service network device to a second non-mobile network device control node requesting a handoff marker, wherein the handoff marker is used to determine if the communications session to be established is a new communications session or a handoff communications session; receiving a response message on the first non-mobile service network device from the second non-mobile network device control node; determining on the first non-mobile network service device whether the response message includes a handoff marker, and if not, sending the generated handoff marker to the second non-mobile network device control node in an update message, wherein the second non-mobile network device uses the generated handoff marker in subsequent messages sent to the first non-mobile network service device to allow handoff and redirection of communications sessions established by the wireless mobile node.
