Abstract: A method and an apparatus for installing a profile in a terminal including a universal integrated circuit card (UICC) corresponding to a smart card security module, which is inserted into a mobile communication terminal and then used are provided. More particularly, a method and an apparatus for remotely installing or removing mobile communication subscriber information in/from a profile of a terminal are provided. The terminal can remotely download the profile from a network server (subscription manager data preparation (SM-DP) or subscription manager secure routing (SM-SR)) without any change in a mobile network operator information technology (IT) system interface rather than downloading the profile of the terminal by the network server.

Abstract: A method and an apparatus for providing a service in a wireless communication system are disclosed. The method and apparatus are directed to 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). The apparatus includes a terminal in the wireless communication system. The terminal includes a transceiver configured to transmit and receive a signal, and a processor configured to receive a first service request related to mission critical push to talk over LTE (MCPTT) over long term evolution (LTE), determine whether a first service corresponding to the first service request and a second service request being currently performed are simultaneously provided, and process the first service and the second service based on a priority of each of the service, services if the first service and the second service are not simultaneously provided.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system, such as LTE. A method for forming a bearer by a mobility management entity (MME) according to an embodiment of the present invention comprises the steps of: receiving a first message including information regarding public safety; and forming a bearer having a priority higher than that of a preset bearer on the basis of the received message. The above-described method makes it possible to form a bearer having a high priority for using a public safety service.

Abstract: The present invention relates to a method and a device for barring access of terminals connected to a base station. A communication method of an Internet protocol multimedia service (IMS) entity, according to one embodiment of the present invention, comprises the steps of: receiving a service request message from a terminal; determining whether to allow an access of a service according to a load status of the IMS and the service requested from the terminal; and transmitting, to the terminal, a connection barring message which includes information for indicating that the access of the terminal is barred, when it is determined to bar the access of the service. According to the one embodiment of the present invention, the IMS can be prevented from being congested due to loads concentrated on IMS entities such as a P-CSCF and the like, and can prevent a situation in which an emergency call or a priority call of a person from a police station or a fire station or the like cannot be received.

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: 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 communication method and apparatus is provided for enhancing video telephony service quality by protecting against call setup failure or service quality degradation caused due to switching of the User Equipment (UE) to a network which does not fulfill the data rate required for video telephony in the video call setup process. The communication method of a terminal in a mobile communication system according to the present disclosure includes transmitting a video telephony call setup request message, receiving a switching command for Circuit Switched Fall Back (CSFB), and setting, if the switching command includes a target cell type set to the 2nd Generation (2G) cell and if a 3rd Generation (3G) cell to which the terminal can access exists, up the video telephony call by switching a connection to the 3G cell.
