A method of a mobility management entity in a wireless communication system includes receiving an attach request for a first network among at least two networks supported by the UE including first capability information including information related to a second network among the at least two networks is, transmitting an attach response indicating completion of attach of the first network to the UE, receiving, from the UE, a session establishment request for the first network after transmitting the attach response, and establishing a session for the first network of the UE through a session management entity supporting mobility between the first network and the second network. ## Claims ### Claim 1 A mobility management entity in a wireless communication system, the mobility management entity comprising: at least one controller configured to: receive, from a user equipment (UE), an attach request for a first network among at least two networks supported by the UE including first UE network capability information indicating support of a second network among the at least two networks, transmit, to the UE, an attach response indicating completion of attach to the first network, receive, from the UE, a session establishment request for the first network, and establish a session for the first network through a session management entity supporting mobility between the first network and the second network, wherein, in case that UE network capability of the second network is disabled, the session establishment request includes information related to a session for the second network. ### Claim 2 (depends on 1) The mobility management entity of claim 1, wherein the attach request includes second UE network capability information indicating that the UE network capabiltiy of the second network is disabled. ### Claim 3 (depends on 1) The mobility management entity of claim 1, wherein the at least one controller is further configured to: in case that the UE network capability of the second network is enabled after the session for the first network is established: receive, from the UE, an update request including third UE network capability information indicating that the UE network capability of the second netowrk is enabled, and transmit, to the UE, an update response in response to the update request. ### Claim 4 (depends on 1) The mobility management entity of claim 1, wherein the information related to the session for the second network includes a session identifier (ID) for the second network. ### Claim 5 A user equipment (UE) in a wireless communication system, the UE comprising: at least one controller configured to: transmit, to a mobility management entity, an attach request for a first network among at least two networks supported by the UE including first UE network capability information indicating support of a second network among the at least two networks, receive, from the mobility management entity, an attach response indicating completion of attach to the first network, transmit, to the mobility management entity, a session establishment request for the first network, and establish a session for the first network through a session management entity supporting mobility between the first network and the second network, wherein, in case that the UE network capability of the second network is disabled, the session establishment request includes information related to a session for the second network. ### Claim 6 (depends on 5) The UE of claim 5, wherein the attach request includes second UE network capability information indicating that the UE network capability of the second network is disabled. ### Claim 7 (depends on 5) The UE of claim 5, wherein the at least one controller is further configured to: in case that the UE network capability of the second network is enabled after the session for the first network is established: transmit, to the mobility management entity, an update request including third UE network capability information indicating that the UE network capabilitye of the second network is enabled, and receive, from the mobility management entity, an update response in response to the update request. ### Claim 8 (depends on 6) The UE of claim 6, wherein the information related to the session for the second network includes a session identifier (ID) for the second network. ### Claim 9 A method performed by a mobility management entity in a wireless communication system, the method comprising: receiving, from a user equipment (UE), an attach request for a first network among at least two networks supported by the UE including first UE network capability information indicating support of a second network among the at least two networks; transmitting, to the UE, an attach response indicating completion of attach to the first network; receiving, from the UE, a session establishment request for the first network; and establishing a session for the first network through a session management entity supporting mobility between the first network and the second network, wherein, in case that UE network capability of the second network is diabled, the session establishment request includes information related to a session for the second network. ### Claim 10 (depends on 9) The method of claim 9, wherein the information related to the session for the second network includes a session identifier (ID) for the second network. ### Claim 11 (depends on 9) The method of claim 9, wherein in case that the UE network capability of the second network is enabled after the session for the first network is established: receiving, from the UE, an update request including third UE network capability information indicating that the UE network capability of the second network is enabled, and transmitting, to the UE, an update response in response to the update request. ### Claim 12 A method performed by a user equipment (UE) in a wireless communication system, the method comprising: transmitting, to a mobility management entity, an attach request for a first network among at least two networks supported by the UE including first UE network capability information indicating support of a second network among the at least two networks; receiving, from the mobility management entity, an attach response indicating completion of attach to the first network; transmitting, to the mobility management entity, a session establishment request for the first network; and establishing a session for the first network through a session management entity supporting mobility between the first network and the second network, wherein, in case that UE network capability of the second network is disabled, the session establishment request includes information related to a session for the second network. ### Claim 13 (depends on 12) The method of claim 12, wherein the information related to the session for the second network includes a session identifier (ID) for the second network. ### Claim 14 (depends on 12) The method of claim 12, wherein in case that the UE network capability of the second network is enabled after the session for the first network is established: transmitting, to the mobility management entity, an update request including the UE network capability information indicating that the UE network capability of the second network is enabled, and receiving, from the mobility management entity, an update response in response to the update request.
