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: A method and an apparatus for controlling Short Message Service (SMS) delivery to a User Equipment (UE) over a Packet-Switched (PS) network without involvement of any Circuit Switched (CS) network node are provided. The method includes receiving subscriber information of a terminal from a Home Subscriber Server (HSS), determining whether the MME supports short message delivery over a Packet-Switched (PS) network, and transmitting, when the MME supports the short message delivery over the PS network, a registration request message including information for routing the short message to the MME to the HSS. The SMS delivery method and apparatus is capable of delivering the SMS message to the UE over the PS network without involvement of the CS network nodes, thereby negating the necessity of CS network nodes for supporting SMS service, resulting in reduction of maintenance and management costs.

Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a paging message in a mobile communication system and, more particularly, to a method and an apparatus for determining a priority between paging messages at a wireless access point and paging a terminal. A method for paging a wireless access point in a mobile communication system according to an embodiment of the present invention comprises the steps of: receiving a plurality of paging messages from a core network; determining a priority between the plurality of paging messages; and transmitting the paging message to a terminal on the basis of the determined priority, wherein information on a number of paging attempts included in the paging messages is used for determining the priorities. The present disclosure relates to a 5G or pre-5G communication system that will be provided to support higher data rates than a post-4G communication system such as LTE.
