摘要：A method and apparatus is provided that improves the quality of voice calls in amobile communication network. The method of performing transmission/reception of
signals in an evolved Node B (eNB) of a mobile communication system includes: receivinga first message including service request information from user equipment (UE);transmitting a second message including the service request information to an MobilityManagement Entity (MME); receiving a third message including context information forthe UE from the MME; and determining an inactivity timer value for the UE based on thecontext 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 setup, thereby preventing part of a caller's voice data from being lost.
