  • Patent number: 7340525
    Abstract: One embodiment of the present invention provides a system that facilitates single sign-on services in a wireless environment. The system operates by receiving a request at an application server from a wireless gateway to access a partner application on behalf of a user. The system then determines if the wireless gateway holds a token granting access to the partner application on behalf of the user. If the wireless gateway does not hold the token, the system redirects the request to a single sign-on server. The single sign-on server then requests user authentication credentials from the user through the wireless gateway. After receiving the user authentication credentials, the system determines if the user is authorized to access the partner application. If so, the single sign-on server issues a token to the wireless gateway. This token grants wireless gateway access to the partner application on behalf of the user.
