Abstract

Methods and systems for restricting communication services over a network. The method includes detecting a Session Initiation Protocol (SIP) register message originating from a specific network Public Land Mobile Network (PLMN) that is included in a restricted PLMN list identified by a P-Access-Network-Information header (P-ANI). The method further includes implementing a policy to remove RCS and presence capability feature tags from a subsequent SIP register message. The lack of feature tags to Serving Call Session Control Function (S-CSCF) will prohibit triggering of Third Party Registration to different application servers.

First claim

What is claimed is:

1. A system comprising:
a node comprising one or more processors and one or more computer storage hardware devices storing computer-usable instructions, that, when used by the one or more processors, cause the one or more processors to:
receive a request from a user device, via a satellite radio access network (RAN) node, to register the user device with the satellite RAN node for one or more services;
register the user equipment with the satellite RAN node for the one or more services;
determine that a first service of the one or more services is not provided by the satellite RAN node based on a determination that the request to register the user device originates from a restricted origin;
receive a request from the user equipment, via the satellite RAN node, to access the first service;
cause the satellite RAN node to respond to the user equipment that the request failed, and that the UE should remain attached to the satellite RAN node; and
cause the satellite RAN to remove of one or more feature capabilities from a communication session established in response to the request to access the first service.

2. The system of claim 1 , wherein the satellite RAN node is a satellite.

3. The system of claim 1 , wherein the causing the satellite RAN node to respond is performed by modifying one or more header fields of a session initiation protocol message.

4. The system of claim 1 , wherein the causing the satellite RAN node is performed by removing one or more feature capabilities.

5. The system of claim 1 , wherein the satellite RAN node is further configured to instruct a policy engine to remove one or more feature capabilities from the communication session.

6. The system of claim 5 , wherein the satellite RAN node is further configured to send a response message to the user device indicating the removal of one or more feature capabilities from the communication session.

7. The system of claim 1 , wherein the satellite RAN node is further configured to receive an indication that the user device supports one or more feature capabilities, and determine whether to remove the one or more feature capabilities based on the indication.

8. A method of managing communication sessions comprising:
receiving, via a satellite radio access network (RAN) node, a request from a user device to register the user device with the satellite RAN node for one or more services;
registering the user equipment with the satellite RAN node for the one or more services;
determining that a first service of the one or more services is not provided by the satellite RAN node based in part on a determination that the request to register the device originates from a restricted origin;
receiving a request from the user equipment to access the first service;
instructing the removal of one or more feature capabilities from a communication session established in response to the request from the user equipment to access the first service; and
causing the satellite RAN node to respond to the user equipment that the request failed, and that the UE should remain attached to the satellite RAN node.

9. The method of claim 8 , wherein the satellite RAN node is a satellite.

10. The method of claim 8 , wherein the causing the satellite RAN node to respond is performed by modifying one or more header fields of a session initiation protocol message.

11. The method of claim 8 , wherein the causing the satellite RAN node is performed by removing one or more feature capabilities.

12. The method of claim 11 , wherein the satellite RAN node is further configured to send a response message to the user device indicating the removal of one or more feature capabilities from the communication session.

13. The method of claim 8 , wherein the satellite RAN node is further configured to instruct a policy engine to remove one or more feature capabilities from the communication session.

14. One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method comprising:
receiving, via a satellite radio access network (RAN) node, a request from a user device to register the user device with the satellite RAN node for one or more services;
registering the user equipment with the satellite RAN node for the one or more services;
determining that a first service of the one or more services is not provided by the satellite RAN node based in part on a determination that the request to register the user device originates from a restricted origin;
receiving a request from the user equipment to access the first service;
instructing the removal of one or more feature capabilities from a communication session established in response to the request from the user equipment to access the first service; and
causing the satellite RAN node to respond to the user equipment that the request failed, and that the UE should remain attached to the satellite RAN node.

15. The one or more non-transitory media of claim 14 , wherein the satellite RAN node is a satellite.

16. The one or more non-transitory media of claim 14 , wherein the causing the satellite RAN node to respond is performed by modifying one or more header fields of a session initiation protocol message.

17. The one or more non-transitory media of claim 14 , wherein the feature capabilities removed are rich communication services (RCS) and presence feature tags.

18. The one or more non-transitory media of claim 17 , wherein the satellite RAN node is further configured to send a response message to the user device indicating the removal of one or more feature capabilities from the communication session.

19. The one or more non-transitory media of claim 14 , wherein the causing the satellite RAN node is performed by removing one or more feature capabilities.

20. The one or more non-transitory media of claim 14 , wherein the satellite RAN node is further configured to receive an indication that the user device supports one or more feature capabilities, and determine whether to remove the one or more feature capabilities based on the indication.
