ENHANCED IMS SERVICES RESTRICTION AND SELECTION CONTROL FOR MOBILE DEVICES ROAMING IN FOREIGN NETWORKS
First Claim
1. A computer-implemented method in a mobile telecommunications network to register a mobile device for Internet Protocol Multimedia Subsystem (IMS) services while the mobile device is roaming in a visited telecommunications network, the method comprising:
- receiving from a mobile device a request for multiple IMS services, the mobile device being located in a visited telecommunications network, the request including a network identifier corresponding to the visited telecommunications and an access identifier corresponding to the radio access technology associated with the mobile device;
querying a policy table to determine whether each requested IMS service is allowed, wherein the querying comprises analyzing the policy table to identify each of the multiple requested IMS services that are whitelisted for the associated visited telecommunications network and radio access type;
in response to determining that one or more requested IMS services are whitelisted for the associated visited telecommunications network and radio access type, registering the mobile device with each of the whitelisted IMS services.

Abstract
A system and method that allows a mobile device to register for IMS services while the mobile device is roaming in a visited telecommunications network is disclosed. The system receives a request for multiple IMS services from a mobile device while the mobile device is roaming in a foreign network. The system uses an identifier of the foreign network and an associated RAT type to query a policy table containing a list of whitelisted IMS services for the foreign network and associated RAT type. The system processes the requested IMS registrations for services that are whitelisted and does not process requested IMS registrations for services that are not on the whitelist.

11. A computer-readable medium storing instructions that, when executed by a processor in an Internet Protocol Multimedia Subsystem (IMS) network, cause the IMS network to execute a method to register a mobile device for IMS services while the mobile device is roaming in a visited telecommunications network, the method comprising:
-
receiving from a mobile device a request for multiple IMS services, the mobile device being located in a visited telecommunications network, the request including a network identifier corresponding to the visited telecommunications and an access identifier corresponding to the radio access technology associated with the mobile device; querying a policy table to determine whether each requested IMS service is allowed, wherein the querying comprises analyzing the policy table to identify each of the multiple requested IMS services that are whitelisted for the associated visited telecommunications network and radio access type; in response to determining that one or more requested IMS services are whitelisted for the associated visited telecommunications network and radio access type, registering the mobile device with each of the whitelisted IMS services. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
