13. A method for (coordinating services in integrated wireless local area network and cellular network systems, the method comprising the steps of:
a user traffic connection between the wireless local area network and the cellular network.
15. The system of claim 14 wherein the wireless local area network notifies the user equipment of an incoming wireless local area network transmission when the user equipment is idle with respect to the wireless local area network and active with respect to the cellular network by sending a message through the cellular network to the user equipment.
16. The system of claim 15 wherein the incoming transmission is transmitted through the cellular network to the user equipment.
17. The system of claim 15 wherein the user equipment is activated with respect to the wireless local area network and the incoming transmission is transmitted through the wireless local area network to the user equipment.
18. The system of claim 15 wherein the user equipment is off with respect to the wireless local area network.
19. The system of claim 14 wherein the cellular network notifies the user equipment of an incoming cellular network transmission when the user equipment is idle with respect to the cellular network and active with respect to the wireless local area network by sending a message through the wireless local area network.
20. The system of claim 19 wherein the incoming transmission is transmitted through the wireless local area network to the user equipment.
21. The system of claim 19 wherein the user equipment is activated with respect to the cellular network and the incoming transmission is transmitted through the cellular network to the user equipment.
22. The system of claim 19 wherein the user equipment is off with respect to the cellular network.
[0007]FIG. 1 is a diagram showing coverage areas for a joint WLAN-cellular system.
[0008]FIGS. 2 through 4 are wireless systems having User-Network scenarios A0 through A2, in accordance with an embodiment of the present invention.
[0009]FIGS. 5 through 7 are wireless systems having User-Network scenarios B0 through B2, in accordance with an embodiment of the present invention.
[0010]FIGS. 8 through 10 are wireless systems having User-Network scenarios C0 through C2, in accordance with an embodiment of the present invention.
The integration of the WLAN and cellular networks is defined by integration level. Level-0 integration means there is no connection between the WLAN and cellular network for exchanging call/session set-up related signaling/control information. There may, however, be a connection for exchanging customer management related signaling/control information, such as authentication, authorization and accounting (AAA) functions. There is also no connection for exchanging user traffic data. Level-i integration means there is a connection between the WLAN and cellular network for exchanging call/session set-up related signaling/control information. There is, however, no connection for exchanging user traffic data. Level-2 integration means there is a connection between the WLAN and cellular network for exchanging call/session set-up related signaling and control information. There is also a connection for exchanging user traffic data.
Referring initially to FIG. 2, User-Network scenario AO of a joint WLAN-cellular system is shown. The WLAN, cellular network, and UE are designated 12, 14, and 16, respectively. As previously mentioned, class-A UE is capable of being simultaneously in WLAN-active mode as well as cellular-active mode. In User-Network scenario-A0, a user traffic connection 18 and signaling/control connection 20 exists between the UE 16 and each of the networks 12, 14.
