US 9,867,084 B2 · Method and apparatus for anchoring terminal in wireless communication system

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention relates to a method and apparatus for anchoring of a terminal in a wireless communication system. The method for anchoring the terminal in the wireless communication system may include receiving attribute information indicating whether at least one gateway operating as an anchor for at least one default Packet Data Network (PDN) connection supports session persistence, detecting a new flow generated by an application, determining whether a further PDN connection is required for the flow on the basis of the attribute information indicating whether at least one gateway supports session persistence, and if no further PDN connection is required for the flow, using an Internet Protocol (IP) address allocated by the at least one gateway as a source IP address of the flow.

Dependent claims

A method of anchoring of a terminal in a wireless communication system, the method comprising:

receiving attribute information indicating whether a gateway operating as an anchor for a default packet data network (PDN) connection supports internet protocol (IP) session persistence;
detecting a flow generated by an application;
determining whether an additional PDN connection is required for the flow based on the attribute information;
and
if no additional PDN connection is required for the flow, using an IP address allocated by the gateway as a source IP address of the flow.

A mobility management entity for anchoring of a terminal in a wireless communication system, the mobility management entity comprising:

a controller configured to determine a gateway operating as an anchor for a default packet data network (PDN) connection of the terminal;
and
a transmitter configured to transmit attribute information indicating whether the determined gateway supports internet protocol (IP) session persistence to the terminal.

A terminal for anchoring in a wireless communication system, the terminal comprising:

a receiver configured to receive attribute information indicating whether a gateway operating as an anchor for a packet data network (PDN) connection supports internet protocol (IP) session persistence;
and
a controller configured to:
detect a flow generated by an application,
determine whether an additional PDN connection is required for the flow based on the attribute information, and
use, if no additional PDN connection is required for the flow, an IP address allocated by the gateway as a source IP address of the flow.
