Method and apparatus for selecting dedicated core network
First Claim
1. A method for transmitting and receiving a signal at an evolved Node B (eNB) of a mobile communication system, the method comprising:
- transmitting a first message to a first mobile management entity (MME);
receiving a reroute command message based on the first message from the first MME, the reroute command message comprising the first message, at least one MME identifier, and a user equipment (UE) identifier, the at least one MME identifier and the UE identifier being a globally unique MME identity (MMEGI) and an additional globally unique temporary UE identity (GUTI), respectively;
determining, based on the MMEGI and the additional GUTI contained in the reroute command message, a second MME; and
transmitting a second message to the second MME based on the reroute command message.

Abstract
Various communication techniques and related systems for a fusion between a 5th generation (5G) communication system and Internet of Things (IoT) technology are provided. A user equipment (UE) is required to select a dedicated core network so as to receive a suitable service. In a method for transmitting and receiving a signal, an enhanced Node B (eNB) of a mobile communication system transmits a first request message to a first mobile management entity (MME), receives a reroute command message based on the first request message from the first MME, and transmits a second message to a second MME based on the reroute command message. Herein, the reroute command message contains the first request message, at least one MME identifier, and a UE identifier.
