Method of multi-radio interworking in heterogeneous wireless communication networks
First Claim
1. A method comprising:
- obtaining wireless local area network (WLAN) information of a WLAN by a serving base station in a cellular network; and
forwarding the WLAN information to a serving device such that the serving device is capable to connect with both the cellular network and the WLAN, wherein the WLAN information is forwarded based on triggering events associated with the serving base station information, WLAN coverage information, or the serving device information.

Abstract
A method of multi-radio interworking to provide integrated cellular and WLAN access for a multi-radio device is provided. A serving base station in a cellular network first obtains wireless local area network (WLAN) information and then forward the WLAN information to a serving device such that the serving device is capable to connect with both the cellular network and a WLAN. The WLAN information may comprise scanning information, WLAN QoS information, WLAN layer-3 information, or additional WLAN access point information. The WLAN information is forwarded based on triggering events associated with the, serving base station information, WLAN coverage information, or the serving device information. Based on the received WLAN information, when entering WLAN coverage, the serving device activates its WLAN access to forward traffic from the cellular access network to the WLAN access network. When leaving WLAN coverage, the serving device deactivates its WLAN access to save power consumption.
