Abstract
A communication apparatus for supporting a registration procedure for an inbound roamer user equipment, ‘UE’, in a visited public land mobile network, ‘VPLMN’ that includes a transceiver and a controller. The controller is configured to: control the transceiver to receive, from a communicator of the VPLMN, a request for authentication information; retrieve the authentication information from a communicator of a home public land mobile network, ‘HPLMN’; and control the transceiver to transmit the authentication information to the serving CSCF of the VPLMN for use in the registration procedure.

Claim
1. A communication apparatus for supporting a registration procedure for an inbound roamer user equipment, �UE�, in a visited public land mobile network, �VPLMN�, the communication apparatus comprising:
a transceiver and a controller, wherein the controller is configured to:
control the transceiver to receive, from a communicator of the VPLMN, a request for authentication information;
retrieve the authentication information from a communicator of a home public land mobile network, �HPLMN�; and
control the transceiver to transmit the authentication information to the communicator of the VPLMN for use in the registration procedure.
2. The communication apparatus according to claim 1, wherein the controller is configured to control the transceiver to receive the request for authentication information from a serving Call Session Control Function, �CSCF�.
3. The communication apparatus according to claim 1, wherein the transceiver is configured to receive the request for the authentication information in a Diameter protocol message.
4. The communication apparatus according to claim 1, wherein the transceiver is configured to transmit the authentication information in a Diameter protocol message.
5. The communication apparatus according to claim 1, wherein the controller is further configured to control the communication apparatus to act as a Home Subscriber Server, �HSS�, towards the communicator of the VPLMN and to act as a visited location register, �VLR�, towards the communicator of the HPLMN.
6. The communication apparatus according to claim 1, wherein the processor is configured to generate and store a subscription profile for the inbound roamer following receipt of the authentication information.
7. The communication apparatus according to claim 1, wherein the processor is configured to generate at least one initial filter criteria, �iFC�, for invoking at least one application server, �AS�.
8. The communication apparatus according to claim 1, wherein the UE is attached to the VPLMN using a circuit switched, �CS�, communication technology and wherein the authentication information comprises CS authentication information.
9. The communication apparatus according to claim 1 comprising an IP Multimedia Subsystem centralized services interworking function, ICS IWF.
10. A communication apparatus for registering an inbound roamer user equipment, �UE�, in a visited public land mobile network, �VPLMN�, the communication apparatus comprising:
a transceiver and a controller wherein the controller is configured to:
control the transceiver to transmit, towards an interworking function of the VPLMN, a request for authentication information; and
control the transceiver to receive the authentication information from the interworking function for use in registering the inbound roamer user.
11. The communication apparatus according to claim 10, comprising a serving Call Session Control Function, �CSCF�.
12. (canceled)
13. A method performed by a communication apparatus for supporting a registration procedure for an inbound roamer user equipment, �UE�, in a visited public land mobile network, �VPLMN�, the method comprising:
receiving, from a communicator of the VPLMN, a request for authentication information;
retrieving the authentication information from a communicator of a home public land mobile network, �HPLMN�; and
transmitting the authentication information to the communicator of the VPLMN for use in said registration procedure.
14. A method performed by a communication apparatus for registering an inbound roamer user equipment, �UE�, in a visited public land mobile network, �VPLMN�, the method comprising:
transmitting, towards an interworking function of the VPLMN, a request for authentication information; and
receiving the authentication information from the interworking function for use in registering the inbound roamer user.
15. A non-transitory computer-readable storage medium storing computer-implementable instructions that, when executed by a programmable communication apparatus, cause the programmable communication apparatus to perform the method of claim 13.
16. A non-transitory computer-readable storage medium storing computer-implementable instructions that, when executed by a programmable communication apparatus, cause the programmable communication apparatus to perform the method of claim 14.
17. The communication apparatus according to claim 3, wherein the Diameter protocol message is a Cx message.
