Abstract:
One disclosure of the present specification provides a method for a proxy-call session control function (P-CSCF) to obtain an identifier of a visited public land mobile network (V-PLMN) in order to register a user equipment (UE) roaming in the V-PLMN into an IP multimedia subsystem (IMS) network. The method may comprise the steps of: receiving a response message from an Interrogating-CSCF (I-CSCF) in response to the transmission of a REGISTER message for registering a user equipment into an IMS network; determining whether the received response message is a 401 unauthorized message; when the received response message is a 401 unauthorized message, transmitting the response message to the user equipment and generating an interface for transmitting and receiving data to and from an entity of an EPC network; and receiving an identifier of the V-PLMN from the entity of the EPC network.

Claim (Index 10):
A proxy-call session control function (P-CSCF) for obtaining an identifier of a visited public land mobile network (V-PLMN) in order to register a user equipment (UE), which has roamed to the V-PLMN, to an IP multimedia subsystem (IMS) network, the P-CSCF comprising:\n a transceiver; and a processor controlling the transceiver, wherein the processor is configured to: control the transceiver to receive a response message from an interrogating-CSCF (I-CSCF) in response to transmission of a register message for registering the UE to the IMS network; verify whether the received response message is a 401 unauthorized message; control the transceiver to transmit the response message to the UE and generate an interface for transmitting and receiving data with respect to an entity of an EPC network, when the received response message is the 401 unauthorized message; and control the transceiver to receive the identifier of the V-PLMN from the entity of the EPC through the interface.
