System and method for providing secure network access in fixed mobile converged telecommunications networks
First Claim
1. A method comprising:
- establishing, by a fixed access device, a connection with a mobile terminal over an air interface;
establishing, by the fixed access device, a limited channel with a service provider network via a broadband interface, wherein the limited channel is restricted to messages needed for authenticating the mobile terminal in the service provider network;
authenticating the mobile terminal with the service provider network via the limited channel using authentication information associated with the mobile terminal, wherein the service provider network has a preexisting relationship with the mobile terminal; and
establishing a secure channel between the fixed access device and the service provider network after authenticating the mobile terminal, wherein the secure channel is not restricted to messages needed for authenticating the mobile terminal in the service provider network.

Abstract
The present disclosure relates generally to systems and methods for providing secure network access in fixed mobile converged telecommunications systems. In one example, a method includes establishing, by a fixed access device, a connection with a mobile terminal over an air interface. The fixed access device may also establish a limited channel with a service provider network via a broadband interface. The limited channel is restricted to messages meeting one or more criterion. The mobile terminal may be authenticated with the service provider network via the limited channel using authentication information associated with the mobile terminal, and the service provider network has a preexisting relationship with the mobile terminal. A secure channel may be established between the fixed access device and the service provider network after the mobile terminal is authenticated. The secure channel may enable the mobile terminal to communicate with the service provider network using messages not meeting the criterion.

8. A method comprising:
-
establishing, by a service provider network configured to provide a communication service to a mobile terminal, a limited channel with a fixed access device via a broadband network, wherein the limited channel is restricted to messages meeting at least one criterion; receiving, by the service provider network via the limited channel, authentication information associated with the mobile terminal, wherein the service provider network has a preexisting relationship with the mobile terminal; determining whether the authentication information is valid; and establishing, by the service provider network, a secure channel with the fixed access device via the broadband network if the authentication information is valid, wherein the secure channel enables the mobile terminal to communicate with the service provider network using messages not meeting the at least one criterion. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method comprising:
-
establishing, by a fixed access device, a connection with a mobile terminal over an air interface; establishing, by the fixed access device, a limited channel with a service provider network via a broadband interface, wherein the limited channel is restricted to messages meeting at least one criterion; passing authentication information from the mobile terminal to the service provider network through the fixed access device; receiving, by the fixed access device, a temporary credential by the service provider network; and establishing a secure channel between the fixed access device and the service provider network using the temporary credential, wherein the secure channel enables the mobile terminal to communicate with the service provider network using messages not meeting the at least one criterion. - View Dependent Claims (15, 16, 17)

18. A device comprising:
-
a wireless interface configured to couple the device with a mobile terminal; a broadband interface configured to couple the device with a broadband network; a processor configured to process a plurality of executable instructions; a memory configured to store the plurality of executable instructions; and the plurality of executable instructions including instructions for; establishing a connection with the mobile terminal over the wireless interface; establishing a limited channel with a service provider network via the broadband interface, wherein the limited channel is restricted to messages needed for authenticating the mobile terminal in the service provider network; passing authentication information from the mobile terminal to the service provider network; and establishing a secure channel with the service provider network after the mobile terminal is authenticated by the service provider network, wherein the secure channel enables the mobile terminal to communicate with the service provider network using messages not needed for authenticating the mobile terminal in the service provider network. - View Dependent Claims (19, 20)
