Abstract: A method for supporting local access and voice communication by a User Equipment (UE) in a wireless network, the method comprises transmitting a message for requesting a Circuit Switch (CS)-based voice service to a eNode B, the UE having a local Internet Protocol (IP)-based Packet Data Network (PDN) connection, and receiving, from the eNode B, a message including information indicating that the local IP-based PDN connection is suspended, if a server managing mobility of the UE determines that suspending the local IP-based PDN connection is supported in a local gateway.

Abstract: The time required to set up a voice call in an exemplary embodiment, in which Circuit Switched Fallback (CSFB) is used, is reduced to provide a voice call service to a User Equipment (UE) in a Long Term Evolution (LTE) system. If a voice call occurs in a UE while the UE accesses the LTE system, the UE using CSFB switches to a 2G/3G legacy system, recycles system information for a 2G/3G cell that the UE has accessed before, and immediately proceeds with voice call setup without receiving system information unnecessary for a CSFB process.

Abstract: Disclosed are: a communication technique for fusing, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4 G system and subsequent systems; and a system thereof. The present disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service and the like) based on 5G communication technology and IoT related technology. The present disclosure presents a method by which a base station determines the approximate location of a terminal on the basis of a reception power report, and sets a codebook subset on the basis of the approximate location of the terminal so as to reduce a channel state report burden.

Abstract: Provided is a method for paging a User Equipment (UE) in an idle state by a Mobility Management Entity (MME) in a wireless communication network in which a Packet Switched (PS) domain and a Circuit Switched (CS) domain coexist. The method includes receiving a CS page message for paging the UE in a CS domain; and upon receiving the CS page message, sending a PS page message for paging the UE in a PS domain, the PS page message including a priority indicator, to an Evolved Node B (ENB) where the UE is located.
