Abstract
A communication method of a mobility management (MM) function is provided. The communication method includes receiving, from a terminal, a signaling message including first information for determining a session management (SM) function to transmit the signaling message, determining an SM function based on the first information, and transmitting the signaling message to the determined SM function.
Claims14
A method performed by a mobility management (MM) entity executing a mobility management function in a wireless communication system, the method comprising:
- receiving, from a terminal, a signaling message to establish a protocol data unit (PDU) session, the signaling message including first information for selecting a session management (SM) entity executing a session management function to transmit the signaling message;
- in case that information on the SM entity corresponding to the first information is not locally configured on the MM entity, transmitting, to a network repository entity executing a network repository function, a request message for requesting second information for identifying a set of SM entities corresponding to the first information, receiving, from the network repository entity, the second information, and selecting the SM entity based on the second information and load conditions of the set of SM entities;
- in case that the information on the SM entity corresponding to the first information is locally configured on the MM entity, selecting the SM entity based on the first information;
- and
- transmitting the signaling message to the selected SM entity.

A mobility management (MM) entity executing a mobility management function in a wireless communication system, the MM entity comprising:
- a transceiver;
- and
- a controller configured to:
- receive, from a terminal via the transceiver, a signaling message to establish a protocol data unit (PDU) session, the signaling message including first information for selecting a session management (SM) entity executing a session management function to transmit the signaling message,
- in case that information on the SM entity corresponding to the first information is not locally configured on the MM entity, transmit, to a network repository entity executing a network repository function via the transceiver, a request message for requesting second information for identifying a set of SM entities corresponding to the first information, receive, from the network repository entity via the transceiver, the second information, and select the SM entity based on the second information and load conditions of the set of SM entities,
- in case that the information on the SM entity corresponding to the first information is locally configured on the MM entity, select the SM entity based on the first information, and
- transmit, via the transceiver, the signaling message to the selected SM entity.

A method performed by a terminal in a wireless communication system, the method comprising:
- generating a signaling message to establish a protocol data unit (PDU) session, the signaling message including first information for selecting a session management (SM) entity executing a session management function to transmit the signaling message;
- and
- transmitting, to a mobility management (MM) entity executing a mobility management function, the signaling message including the first information,
- wherein the transmitting of the signaling message triggers the MM entity to, in case that information on the SM entity corresponding to the first information is not locally configured on the MM entity, transmit, to a network repository entity executing a network repository function, a request message for requesting second information for identifying a set of SM entities corresponding to the first information, receive, from the network repository entity, the second information, and select the SM entity based on the second information and load conditions of the set of SM entities, and, in case that the information on the SM entity corresponding to the first information is locally configured on the MM entity, select the SM entity based on the first information.

A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- generate a signaling message to establish a protocol data unit (PDU) session, the signaling message including first information for selecting a session management (SM) entity executing a session management function to transmit the signaling message, and
- transmit, to a mobility management (MM) entity executing a mobility management function via the transceiver, the signaling message including the first information,
- wherein the transmitting of the signaling message triggers the MM entity to, in case that information on the SM entity corresponding to the first information is not locally configured on the MM entity, transmit, to a network repository entity executing a network repository function, a request message for requesting second information for identifying a set of SM entities corresponding to the first information, receive, from the network repository entity, the second information, and select the SM entity based on the first information and the second information, and, in case that the information on the SM entity corresponding to the first information is locally configured on the MM entity, select the SM entity based on the first information.
