Abstract: Provided are a communication method and system enabling convergence of 5G communication and IoT technology to achieve higher data rates for beyond 4G communication systems.
In addition, provided is a method for transmitting a power headroom report (PHR) by a user equipment (UE) in a mobile communication system. The method includes: receiving a first PHR configuration information for a first base station (first ENB); receiving a second PHR configuration information for a second ENB; generating, when the UE has dual connectivity to the first ENB and the second ENB, a dual connectivity PHR containing PHR information for the first ENB and second ENB based on a dual connectivity PHR format; and sending the dual connectivity PHR. There is also provided a user equipment supporting the above method. There is further provided a base station and operation method therefor that enable the user equipment to have dual connectivity.

Abstract: Disclosed are a method and an apparatus for selecting a domain for a voice call in a mobile communication network. A terminal, which uses VoLTE, receives, from a network, identification information indicating whether IMS Voice over PS (IMS VoPS) is supported, determines whether the network supports IMS VoPS and determines a domain (PS or CS) to which a voice service will be provided through the network according to the determination result.

Abstract: A method and a device for maintaining an emergency call service through a packet network in a mobile communication network are provided. UE using VoLTE receives identification information indicating whether an IMS Voice over PS (VoPS) is supported from a network to determine whether the IMS VoPS of the network is supported, and processes paging for a CS voice call according to the determination result if the emergency call service continues through the packet network.

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.
