Abstract

A method, system and apparatus for internetworking a WWAN and a WLAN are disclosed. More specifically, a method, system and apparatus for providing WWAN services to a mobile station serviced by a WLAN are disclosed. An MSC is provisioned to serve a WLAN. The MSC that serves the WLAN receives WWAN messages that provide a WWAN service. The MSC forms SIP messages using the received WWAN messages and delivers the SIP messages to the WLAN via an IP link. The WLAN delivers the SIP messages to the mobile station via a WLAN air interface protocol. Under one embodiment, the WWAN service is a Short Message Service (SMS). Under another embodiment, the WWAN service is a Message Wait Notification (MWN). Under another embodiment, an MSC that services the WLAN and an MSC servicing the WWAN cooperate to provide TFO call services between an mobile station operating in the WLAN and a mobile station operating in the WWAN.

Claims

1. A method of providing a wireless wide area network (WWAN) service to a mobile station serviced in a wireless local area network (WLAN), comprising:

provisioning a MSC to serve the WLAN;

the MSC that serves the WLAN receiving WWAN messages that provide the WWAN service;

the MSC forming SIP messages using the received WWAN messages;

the MSC delivering the SIP messages to the WLAN via an IP link;

the WLAN delivering the SIP messages to the mobile station via a WLAN air interface protocol.

2. The method of claim 1 wherein the WWAN service is a Short Message Service (SMS) and wherein the WWAN includes a SMS Center for delivering SMS messages on the WWAN and wherein the MSC forms SIP Invite messages with SMS payload and delivers said SIP Invite messages to the WLAN.

3. The method of claim 1 wherein the WWAN service is a Message Wait Notification (MWN) and wherein the WWAN provides MWN messages to the WWAN and wherein the MSC forms SIP Invite messages with MWN information and delivers said SIP Invite messages to the WLAN.

4. The method of claim 1 wherein the MSC that services the WWAN and an MSC servicing the WWAN cooperate to provide TFO call services between an mobile station operating in the WLAN and a mobile station operating in the WWAN.
