Method for supporting PDN GW selection

A method by a base station in a wireless communication system, the method comprising:

• transmitting, to a mobility management entity (MME), a message related to a terminal;
• and
• receiving, from the MME, a response message in response to the message,
• wherein information on an access point name (APN) for a packet data network (PDN) connectivity request is acquired at the MME,
• wherein whether the APN is authorized for a local internet protocol access (LIPA) is identified based on subscription information of the terminal,
• wherein whether an address of a gateway collocated with the base station is included in the message is identified in case that the APN is authorized for the LIPA based on the subscription information of the terminal, and
• wherein the PDN connectivity request is rejected in a case that the address is not included in the message and the APN is authorized for the LIPA based on the subscription information of the terminal.

An apparatus in a wireless communication system, the apparatus comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, a message related to a terminal,
• receive, from the terminal, information on an access point name (APN) for a packet data network (PDN) connectivity request,
• identify whether the APN is authorized for a local internet protocol access (LIPA) based on subscription information of the terminal,
• identify whether an address of a gateway collocated with the base station is included in the message in case that the APN is authorized for the LIPA based on the subscription information of the terminal, and
• reject the PDN connectivity request in a case that the address is not included in the message and the APN is authorized for the LIPA based on the subscription information of the terminal.
