    Abstract: A method of supporting inter-system mobility of a first entity includes receiving a create session request message including information about an Access Point Name (APN), for which a user equipment requests a packet data network (PDN) connection, subscriber identification information of the user equipment, and a field indicating capability information of the user equipment about slice identification information, determining, based on the create session request message, whether movement to a 5G system (5GS) is required for the PDN connection, transmitting, based on a result of the determining, to a second entity, a subscriber information request including the subscriber identification information and the APN information, receiving, from the second entity, a response to the subscriber information request including identification information of one or more subscribed network slices corresponding to the subscriber identification information, and providing, to the user equipment, at least one piece of identification information of the one or more subscribed network slices.

    Abstract: A method and apparatus is provided that improves the quality of voice calls in a mobile communication network. The method of performing transmission/reception of signals in an evolved Node B (eNB) of a mobile communication system includes: receiving a first message including service request information from user equipment (UE); transmitting a second message including the service request information to an Mobility Management Entity (MME); receiving a third message including context information for the UE from the MME; and determining an inactivity timer value for the UE based on the context information. The method and apparatus can maintain, when a voice call is created, connection with calling UE from when the called UE answers the call until the call is set up, thereby preventing part of a caller's voice data from being lost.
