WIRELESS ACCESS NETWORK AND METHOD FOR HANDOVER OF MOBILE TERMINALS IN IDLE MODE
First Claim
Patent Images
1. A method for handover in a wireless access network for a mobile station in idle mode comprising:
- receiving a location update request message from a relay paging controller when a mobile station has changed paging groups;
determining whether the mobile station has switched access service networks based on a network address of the relay paging controller; and
when the mobile station has switched between access service networks, sending a handover request message to a proxy mobile client of the mobile station to provide an address of a target foreign agent for use when routing subsequent communications to the mobile station.

16. A paging controller comprising:
-
network interface circuitry to receive a location update request message from a relay paging controller when a mobile station has changed paging groups; and processing circuitry to determine whether the mobile station has switched access service networks by comparing a network address of the relay paging controller received in the location update request message with a network address of an anchor paging controller. - View Dependent Claims (17, 18, 19, 20)

21. A wireless communication system comprising:
-
a plurality of access service networks for providing wireless communications with a mobile station wherein a location update request message is received from a relay paging controller of a current one of the access service networks from a prior one of the access service networks when the mobile station changes paging groups, wherein when the relay paging controller determines that the mobile station has switched between access service networks based on a network address of the relay paging controller, and the relay paging controller sends a handover request message to a proxy mobile client of the mobile station within a first of the access service networks to indicate an address of a target foreign agent within the current access service network. - View Dependent Claims (22, 23, 24, 25)

26. A machine-accessible medium that provides instructions, which when accessed, cause a machine to:
-
determine whether a mobile station has switched access service networks based on a network address of a relay paging controller received in a location update request message sent when the mobile station has changed paging groups; and send a handover request message to a proxy mobile client of the mobile station to provide an address of a target foreign agent for use when routing subsequent communications to the mobile station when the mobile station has switched between access service networks. - View Dependent Claims (27, 28)

29. A paging controller system comprising:
-
network interface circuitry to receive a location update request message from a relay paging controller when a mobile station has changed paging groups; random access memory to store a network address of the anchor paging controller; and processing circuitry to determine whether the mobile station has switched access service networks by comparing a network address of the relay paging controller received in the location update request message with the network address of an anchor paging controller. - View Dependent Claims (30, 31)
