and transmitting a non-access stratum (NAS) message comprising a UE capability identifier to the base station, wherein the UE capability identifier is assigned by the core network through NAS signaling. ### Claim 2 (depends on 1) The communication method of claim 1, wherein the UE capability information request comprises radio access technology (RAT) type information, and the UE capability identifier is configured based on the RAT type information. ### Claim 3 (depends on 1) The communication method of claim 1, wherein the UE capability identifier comprises a public land mobile network (PLMN) based UE capability identifier or a manufacturer-based UE capability identifier. ### Claim 4 (depends on 3) The communication method of claim 3, further comprising storing the assigned PLMN-specific UE capability identifier, wherein a certain number of PLMN-specific UE capability identifiers are stored in the UE, and when a number of PLMN-specific UE capability identifiers exceeds the certain number, previously stored PLMN-specific UE capability identifiers are deleted. ### Claim 5 (depends on 3) The communication method of claim 3, wherein the transmitting of the NAS message comprising the UE capability identifier comprises transmitting an NAS message comprising the manufacturer-specific UE capability identifier when the UE is not assigned with the PLMN-specific UE capability identifier. ### Claim 6 (depends on 1) The communication method of claim 1, further comprising: determining whether capability information of the UE has changed; and transmitting a message comprising information indicating that a new PLMN-specific UE capability identifier needs to be updated, based on a result of the determining. ### Claim 7 (depends on 1) The communication method of claim 1, further comprising storing the UE capability identifier corresponding to UE capability information, and the UE capability information in a mapping table form. ### Claim 8 A communication method of an entity in a core network in a wireless communication system, the communication method comprising: transmitting a message requesting UE capability information to a UE through a base station; and receiving a non-access stratum (NAS) message comprising a UE capability identifier through the base station, wherein the UE capability identifier is assigned by the core network through NAS signaling. ### Claim 9 (depends on 8) The communication method of claim 8, wherein the UE capability information request comprises radio access technology (RAT) type information, and the UE capability identifier is configured based on the RAT type information. ### Claim 10 (depends on 8) The communication method of claim 8, further comprising: identifying the UE capability identifier; and determining whether UE capability information corresponding to the UE capability identifier are stored, wherein the UE capability identifier and the UE capability information are stored in a mapping table form. ### Claim 11 (depends on 8) The communication method of claim 8, wherein the UE capability identifier comprises a public land mobile network (PLMN)-specific UE capability identifier or a manufacturer-specific UE capability identifier. ### Claim 12 (depends on 11) The communication method of claim 11, wherein the receiving of the NAS message comprising the UE capability identifier comprises receiving an NAS message comprising the manufacturer-based UE capability identifier when the UE is not assigned with the PLMN-based UE capability identifier. ### Claim 13 (depends on 8) The communication method of claim 8, further comprising receiving a message comprising information indicating that a new PLMN-based UE capability identifier needs to be updated, based on determination of whether capability information of the UE has changed, when capability information of the UE has changed. ### Claim 14 A user equipment (UE) for providing UE capability information in a wireless communication system, the UE comprising: a transceiver; and at least one processor coupled with the transceiver configured to receive a UE capability information request triggered by a core network from a base station and transmit a non-access stratum (NAS) message comprising a UE capability identifier to the base station, wherein the UE capability identifier is assigned by the core network through NAS signaling. ### Claim 15 An entity in a core network configured to communicate based on user equipment (UE) capability information in a wireless communication system, the entity comprising: a transceiver; and at least one processor coupled with the transceiver configured to transmit a message requesting UE capability information to a terminal through a base station and receive a non-access stratum (NAS) message comprising a UE capability identifier through the base station, wherein the UE capability identifier is assigned by the core network through NAS signaling.
