Abstract

The present disclosure relates to a communication technique that combines a 5G communication system for supporting a data rate that is higher than that of a beyond 4G system with IoT technology, and a system thereof. The present disclosure may be applied to intelligent services on the basis of 5G communication technology and IoT related technology, such as smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services.
A method by a mobility management (MM) function entity is provided. The method includes receiving a message including session information for a terminal in an idle mode, transmitting a paging message for the terminal based on the message, receiving a service request message for the terminal from a base station, transmitting an interface configuration request message including the session information to the base station based on the session information, receiving an interface configuration response message from the base station, and transmitting information for configuring an interface between a user plane gateway (UP GW) corresponding to the session information and the base station.

First claim

What is claimed is:

1 . A method by a mobility management (MM) function entity, the method comprising:
receiving a message including session information for a terminal in an idle mode; transmitting a paging message for the terminal based on the message; receiving a service request message for the terminal from a base station; transmitting an interface configuration request message including the session information to the base station based on the session information; receiving an interface configuration response message from the base station; and transmitting information for configuring an interface between a user plane gateway (UP GW) corresponding to the session information and the base station.

2 . The method of claim 1 , wherein at least one of the interface configuration request message or the service request message comprises the session information.

3 . The method of claim 1 , wherein a connection is configured with respect to the UP GW that corresponds to the session information among a plurality of UP GWs that are connected before the terminal is switched to the idle mode.

4 . A mobility management (MM) function entity comprising:
a transceiver configured to transmit and receive signals; and a controller configured to:
receive a message including session information for a terminal in an idle mode,
transmit a paging message for the terminal based on the message,
receive a service request message for the terminal from a base station,
transmit an interface configuration request message including the session information to the base station based on the session information,
receive an interface configuration response message from the base station, and
transmit information for configuring an interface between a user plane gateway (UP GW) corresponding to the session information and the base station.

5 . The MM function entity of claim 4 , wherein at least one of the interface configuration request message and the service request message comprises the session information.

6 . The MM function entity of claim 4 , wherein a connection is configured with respect to the UP GW that corresponds to the session information among a plurality of UP GWs that are connected before the terminal is switched to the idle mode.

7 . A method for operating a session management (SM) function entity, the method comprising:
receiving information indicating that there is data to be transmitted from a user plane gateway (UP GW) to a terminal in an idle mode; transmitting an interface configuration request message including session information for the terminal to a mobility management (MM) function entity; and receiving from the MM function entity an interface configuration response message including information for configuring an interface between the UP GW corresponding to the session information and a base station.

8 . The method of claim 7 , wherein a connection is configured with respect to the UP GW that corresponds to the session information among a plurality of UP GWs that are connected before the terminal is switched to the idle mode.

9 . A session management (SM) function entity comprising:
a transceiver configured to transmit and receive signals; and a controller configured to:
receive information indicating that there is data to be transmitted from a user plane gateway (UP GW) to a terminal in an idle mode,
transmit an interface configuration request message including session information for the terminal to a mobility management (MM) function entity, and
receive from the MM function entity an interface configuration response message including information for configuring an interface between the UP GW corresponding to the session information and a base station.

10 . The SM function entity of claim 9 , wherein a connection is configured with respect to the UP GW that corresponds to the session information among a plurality of UP GWs that are connected before the terminal is switched to the idle mode.
