Method and system for using an integrated subscriber identity module in a network interface unit
View Patent ↗Subscriber-associated authentication, authorization and policy control information can be stored on a SIM (preprogrammed or user programmed), thereby facilitating grant or denial of access to services at an NIU while the programmed SIM or virtual SIM resides in the NIU. A provider can store a message in the SIM based on a payment, which determines the level and period of services to be provided. The SIM can be removed and used at any of a plurality of NIUs, thereby facilitating payment for the services following the SIM.
1. A method for providing portability of a suite of subscription services between a plurality of network interface units, comprising:
processing at a service provider a request for the services received from a user device coupled to one of the network interface units, the request containing a unique identifier retrieved from and corresponding to a SIM device coupled to the one of the network interface units;
processing at the service provider account and billing information to be used for payment of the services, the account and billing information being received from the SIM device coupled to the one of the network interface unit;
generating at the service provider a credit message that credit for the suite of services has been granted, the message being capable of authorizing the network interface unit to grant access to any of the requested services when the SIM device is used in the network interface unit; and
downloading the credit message to the SIM device.
2. The method of claim 1 wherein the SIM device does not grant access to all of the requested services at a given user device coupled to the network interface device based on a subscriber profile that restricts access to certain content at the given user device.
3. A system comprising:
an interface at a service provider operable to receive a request for subscription services from a user device;
an authorization module at the service provider operable to process the request for subscription services received from the user device having a SIM device coupled to a network interface unit, wherein the request includes a unique identifier associated with the SIM device coupled to the network interface unit;
an account management module operable to electronically process account and billing information received from the SIM device via the user device, the account and billing information to be used as payment for the subscription services, the account and billing information being associated with the unique identifier associated with the SIM device coupled to the network interface unit;
wherein the authorization module is operable to generate a credit message approving access to the subscription services, the credit message being capable of authorizing the network interface unit to grant access to any of a plurality of authorized subscription services by the user device when the SIM device is used in the network interface unit at the user device; and
wherein the interface is operable to transmit the credit message to the SIM device via the user device and network interface unit.
4. The system of claim 3 , wherein the credit message is communicated from a headend location to a SIM device location over a network.
5. The system of claim 4 , wherein the SIM device location at which the message is received is different than a network interface unit location of one or more of the plurality of network interface units where the subscription services can be retrieved.
6. The system of claim 5 , wherein the SIM device location at which the message is received is the same as a network interface unit location associated with the network interface unit.
7. The system of claim 3 , wherein the authorization module is further operable to generate a denial message indicating that access to subscription services by the SIM device is denied, and the interface is operable to transmit the denial to the SIM device location.
