Abstract

Claims (40)

1. A method performed by a user equipment (UE) in a communication system, the method comprising:

transmitting, to an access and mobility management function (AMF), a registration request message including a manufacturer assigned radio capability identifier (ID), the manufacturer assigned radio capability ID uniquely identifying UE capability by a UE manufacturer being assigned by the UE manufacturer;

receiving, from a base station which is received a request to provide UE capability information from the AMF, a request message for requesting the UE capability information;

transmitting, to the base station, a message including the UE capability information, as a response to the request message; and

receiving, from the AMF, a registration accept message including a public land mobile network (PLMN) assigned radio capability ID, as a response to the registration request message,

the PLMN assigned radio capability ID uniquely identifying UE capability in a serving PLMN being applied for the serving PLMN,

wherein the PLMN assigned radio capability ID is associated with the UE capability information.

2. The method of claim 1 , further comprising:

identifying whether a size of the UE capability information exceeds a predetermined size; and

in case that the size of the UE capability information exceeds the predetermined size, performing a segmentation for the UE capability information,

wherein the UE capability information is transmitted in at least one segmented radio resource control (RRC) message.

3. A method performed by an access and mobility management function (AMF) in a communication system, the method comprising:

receiving, from a user equipment (UE), a registration request message including a manufacturer assigned radio capability identifier (ID), the manufacturer assigned radio capability ID uniquely identifying UE capability by a UE manufacturer being assigned by the UE manufacturer;

transmitting, to a base station, a message to request UE capability information, based on the manufacturer assigned radio capability ID being not available in the AMF;

receiving, from the base station, the UE capability information; and

transmitting, to the UE, a registration accept message including a public land mobile network (PLMN) assigned radio capability ID, as a response to the registration request message, the PLMN assigned radio capability ID uniquely identifying UE capability in a serving PLMN being applied for the serving PLMN,

wherein the PLMN assigned radio capability ID is associated with the UE capability information.

4. The method of claim 3 , further comprising:

storing the UE capability information with the PLMN assigned radio capability ID.

5. A user equipment (UE) in a communication system, the UE comprising:

a transceiver; and

a controller configured to:

control the transceiver to transmit, to an access and mobility management function (AMF), a registration request message including a manufacturer assigned radio capability identifier (ID), the manufacturer assigned radio capability ID uniquely identifying UE capability by a UE manufacturer being assigned by the UE manufacturer,

control the transceiver to receive, from a base station which is received a request to provide UE capability information from the AMF, a request message for requesting the UE capability information,

control the transceiver to transmit, to the base station, a message including the UE capability information, as a response to the request message, and

control the transceiver to receive, from the AMF, a registration accept message including a public land mobile network (PLMN) assigned radio capability ID, as a response to the registration request message, the PLMN assigned radio capability ID uniquely identifying UE capability in a serving PLMN being applied for the serving PLMN,

wherein the PLMN assigned radio capability ID is associated with the UE capability information.

6. The UE of claim 5 ,

wherein the controller is further configured to identify whether a size of the UE capability information exceeds a predetermined size, and in case that the size of the UE capability information exceeds the predetermined size, perform a segmentation for the UE capability information, and

wherein the UE capability information is transmitted in at least one segmented radio resource control (RRC) message.

7. An access and mobility management function (AMF) in a communication system, the AMF comprising:

a transceiver; and

a controller configured to:

control the transceiver to receive, from a user equipment (UE), a registration request message including a manufacturer assigned radio capability identifier (ID), the manufacturer assigned radio capability ID uniquely identifying UE capability by a UE manufacturer being assigned by the UE manufacturer,

control the transceiver to transmit, to a base station, a message to request UE capability information, based on the manufacturer assigned radio capability ID being not available in the AMF,

control the transceiver to receive, from the base station, the UE capability information, and

control the transceiver to transmit, to the UE, a registration accept message including a public land mobile network (PLMN) assigned radio capability ID, as a response to the registration request message, the PLMN assigned radio capability ID uniquely identifying UE capability in a serving PLMN being applied for the serving PLMN,

wherein the PLMN assigned radio capability ID is associated with the UE capability information.

8. The AMF of claim 7 ,

wherein the controller is further configured to store the UE capability information with the PLMN assigned radio capability ID.
