    Abstract: The present disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure can be applied to an intelligent service (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related service, and the like) on the basis of a 5G communication technology and an IoT related technology. A method for a terminal according to the present invention comprises the steps of: receiving system information; receiving a signal from a service cell when a discontinuous reception (DRX) timer expires; determining the mobility of the terminal on the basis of the signal; and omitting neighboring cell measurement when the terminal has no mobility.

    Abstract: A system and communication method for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), and for application to intelligent services based on the 5G communication and the IoT-related technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for processing a packet by a transmission device in a wireless communication system according to the present disclosure comprises the steps of: checking whether a data radio bearer (DRB) mapped to a quality of service (QOS) flow changes from a first DRB to a second DRB; and when the DRB changes from the first DRB to the second DRB, transmitting, to a reception device, information on a last packet transmitted through the first DRB in the QoS flow.
