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.

Abstract: The present disclosure relates to a communication technique and system for combining 5G communication systems with IoT technologies to achieve a higher data rate beyond 4G systems. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail businesses, and security and safety related services) on the basis of 5G communication technologies and IoT related technologies. As an embodiment of the present specification, there is provided a method of signal transmission and reception for a user equipment (UE) in a mobile communication system. The method may include: receiving first information for providing a service from a service providing server; receiving second information for managing a session associated with the service from the service providing server; and sending a signal to the service providing server on the basis of the first information and the second information. In one embodiment of the present specification, when a sponsored service and a WebRTC service are provided, service provision information and session management information are associated together. Thereby, it is possible to improve user convenience and service effectiveness.

Abstract: An example method for an electronic device includes determining, while accessing a first network supporting a first Radio Access Technology (RAT), to change a serving RAT to a second RAT, identifying a time interval in which the electronic device maintains an active state to communicate with the first network, scanning the second RAT during a period determined based on a start timing or an end timing of the time interval, and accessing a second network supporting the second RAT based on a result of the scanning.
