Session key management for public wireless LAN supporting multiple virtual operators
View Patent ↗A method and apparatus for managing a session key for allowing a mobile terminal to access a wireless local area network (WLAN). The invention provides for establishing a first secure channel between an access point and a virtual operator, and suggesting a session key to the virtual operator from the access point. A second secure channel is established between the virtual operator and a user, and the session key is sent to the user via the second secure channel upon successful user authentication. The mobile terminal accesses the WLAN using the session key.
1. A mobile terminal, comprising:
means for forwarding a request for access to a wireless local area network (WLAN); and
means for communicating with a virtual operator via a second secure channel to authenticate the mobile terminal, wherein a selected session key is communicated to said mobile terminal via the second secure channel, wherein said selected session key was previously chosen by said WLAN and was communicated to said virtual operator by said WLAN via a first secure channel; and further wherein after receiving said selected session key said mobile terminal communicates using said session key.
2. The mobile terminal according to claim 1 , wherein the mobile terminal communicates using said session key upon receiving notification of successful user authentication from said virtual operator.
3. The mobile terminal according to claim 1 , wherein said virtual operator comprises one of an Internet Service Provider, a cellular provider and a credit card provider.
