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.
