NETWORK SERVICE ACCESS CONTROL BY AUTHORIZATION SERVER
First Claim
1. A method comprising, by an authorization server of a telecommunications network:
- determining that a terminal is roaming in the telecommunications network;
receiving service data associated with the terminal of the telecommunications network from a home authorization server of a home network via a communications interface;
determining that a portion of the service data corresponds with a predetermined network service not supported by the telecommunications network;
determining modified service data to remove the ability of the terminal to use the predetermined network service not supported by the telecommunications network but supported by the home network at least partly by removing the portion of the service data; and
transmitting, via the communications interface, the modified service data to a control device of the telecommunications network.

Abstract
In some implementations, a telecommunications network can include an authorization server, e.g., a Diameter Routing Agent. The authorization server can receive service data associated with a network terminal from a home authorization server. The authorization server can determine that a portion of the service data corresponds with a predetermined network service and remove the portion of the service data to provide modified service data. The authorization server can transmit the modified service data to a control device of the network. In some examples, the control device can determine a gateway device identified in the modified service data and transmit an association message to the gateway device on behalf of the terminal. In some examples, the control device can receive a request for a network service from the terminal, determine that the modified service data does not authorize the network service, and transmit a rejection message to the terminal.
