Network service access control
First Claim
1. A telecommunications network, comprising:
- a home subscriber server (HSS);
an authorization server that is different from the HSS; and
an anchoring network device communicatively connectable with user equipment, wherein the anchoring network device is configured to;
receive from the user equipment a first service message associated with a communication session, the first service message including information of a first session attribute;
determine identification information of the user equipment, wherein the user equipment is associated with a first party of one or more parties of the communication session and the identification information identifies a visited network in which the user equipment is roaming;
retrieve authorization information corresponding to the identification information from the authorization server;
in response to the authorization information indicating the first session attribute is not permitted, determine a second session attribute different from the first session attribute based at least in part on the first session attribute;
determine a second service message including information of the second session attribute; and
transmit the second service message to one or more parties of the telecommunication session via a communications interface of the anchoring network device.

Abstract
In some implementations, a telecommunications network can include an anchoring network device. The anchoring network device can receive, from a first party of a communication session, a service message including information of a first session attribute and associated with identification information of a party of the communication session. The anchoring network device can retrieve, from an authorization registry, authorization information corresponding to the identification information. In response to the authorization information indicating the first capability is not permitted, the anchoring network device can determine a status message based at least in part on the service message and transmit the status message via a communications interface. The status message can include a service-failure message or a second service message including information of a second, different session attribute.

14. A method comprising, by a processor of an anchoring network device of a telecommunications network:
-
receiving, from user equipment of a telecommunications network, a first service message associated with a communication session, the first service message including information of a first session attribute; determining identification information of the user equipment, wherein the user equipment is associated with a first party of one or more parties of the communication session and the identification information identifies a visited network in which the user equipment is roaming; retrieving authorization information corresponding to the identification information from the authorization server; in response to the authorization information indicating the first session attribute is not permitted, determining a second session attribute different from the first session attribute based at least in part on the first session attribute; determining a second service message including information of the second session attribute; and transmitting the second service message to one or more parties of the telecommunication session via a communications interface of the anchoring network device.
