Abstract
A system for employing a wireless local area network (WLAN) as a cellular network routing area includes a cellular network, which is capable of determining a location where a service request is made. The cellular network includes a packet-based support node B, which determines if the request can be serviced through a WLAN, which is identified in the cellular network as a routing area. Packet data protocol context is maintained while servicing the request using the WLAN to provide smooth interworking between the WLAN and the cellular network.
Claims18
A method for registering a Wireless Local Area Network (WLAN) as a cellular network routing area, comprising the steps of:
- determining a location of a service request from a user within a cellular network;
- determining whether the location is in or near a WLAN access point;
- if at or near the WLAN access point, maintaining packet data protocol (PDP) context while servicing the request using the WLAN such that interworking between the WLAN and the cellular network is provided.
A system for employing a Wireless Local Area Network (WLAN) as a cellular network routing area, comprising:
- a cellular network, which is capable of determining a location where a service request is made;
- the cellular network comprising a packet-based support node, which determines if the request can be serviced through a WLAN, which is identified in the cellular network as a routing area;
- means for maintaining packet data protocol (PDP) context while servicing the request using the WLAN to provide smooth handoff between the WLAN and the cellular network.
