Technique for interworking a wlan with a wireless telephony network
First Claim
1. A method for interworking a WLAN network accessed by at least one mobile terminal user, and a wireless telephony network, comprising the steps of:
- establishing a wireless telephony communications link between the WLAN and the wireless telephony network;
receiving in the WLAN a first control communications signal from the at least one mobile terminal user and communicating the first control communications signal from the WLAN network to a wireless telephony network across the wireless telecommunications link.

Abstract
Interworking of a wireless telephony network (12) with a wireless Local Area Network (10) serving at least one mobile terminal user (14) is accomplished by reserving a General Packet Radio Service (GPRS) communications channel (20) of the wireless telephony network. Control communications signals received in the WLAN (10) from the mobile terminal user are communicated across the GPRS channel (20) to the wireless telephone network (12) and likewise, control communications signals from the wireless telephony network pass to the WLAN over the channel. Using the GPRS channel to carry control communications signals between the WLAN (10) and the WLAN (12) affords the advantage of a loose coupling without the risk of sending sensitive control information over a non-secure link.

15. A method for interworking a WLAN network accessed by a plurality of wireless terminals, and a wireless telephony network, comprising the steps of:
-
establishing a wireless telephony communications link between the WLAN and the wireless telephony network;
multiplexing first control communications signals received from the plurality of mobile terminal users into a first combined signal stream;
communicating the first combined signal stream from the WLAN network to a wireless telephony network across the wireless telecommunications link;
transmitting a second combined communications signal stream of multiplexed control communications signals from the wireless telephony network to the WLAN across the wireless telephony communications link;
de-multiplexing the second combined signal stream into constituent control signals; and
distributing the constituent signals to corresponding mobile terminals users in communication with the WLAN. - View Dependent Claims (17)
