Abstract:
A communication technology for converging a 5th-generation (5G) communication system for supporting a higher data rate after a 4th-generation (4G) system to an Internet of things (IoT) technology and a system thereof are provided. A method for connecting to a network by a terminal in a mobile communication system wherein a first communication network and a second communication network are operable, and an apparatus thereof are provided. The method includes transmitting, to a mobility management function, information on supportable communication network for the terminal and an attach request message including a packet data unit (PDU) session request, receiving an internet protocol (IP) address allocated based on the information on supportable communication network and an attach accept message including a PDU session response, and connecting to a network based on the IP address.
Abstract:
A method that can increase network performance and user perceived service quality by allocating more radio resources to user data through a non-3GPP Access Network (AN) in a wireless communication system such as LTE is provided. Use of a 3GPP AN or a non-3GPP AN may be set in a user equipment or set according to a policy received from a policy server such as ANDSF. A scheme for dynamically updating and applying a policy according to user and AN conditions is provided. The scheme provides two approaches for determining whether to apply a policy according to user and the AN conditions.
Abstract:
According to an embodiment of the disclosure, a base station (BS) is configured to: transmit traffic to at least one user equipment (UE) connected to the BS via a unicast scheme; based on information about a number of UEs connected to the BS to use a particular application, a particular service, or a particular session, or information of traffic to be used by the UE, determine whether to switch a transmission scheme of the traffic from the unicast scheme to a broadcast/multicast scheme; and as the broadcast/multicast scheme is determined as the transmission scheme of the traffic, transmit a message informing that the transmission scheme of the traffic is to be switched.
Abstract:
Provided are a method and apparatus for transmitting and receiving a data packet in a wireless communication system, the method including: provisioning at least one virtual network function (VNF) corresponding to some or all of a plurality of network functions (NFs) included in a first core network; registering, in the first core network, the provisioned at least one VNF; receiving a first packet from a user equipment (UE) and determining a path through which the first packet is to be transmitted, from among a first path between a user plane function (UPF) of the first core network and an electronic device and a second path between a UPF of a second core network and the electronic device; and transmitting the first packet through the determined path.
Abstract:
A method, performed by an access and mobility management function (AMF), of providing information for a vehicle-to-everything (V2X) service is provided. The method includes receiving, from a user equipment (UE), a registration request message including information indicating that the UE is a V2X terminal, selecting, based on the registration request message, a policy control function (PCF) supporting the V2X service, receiving V2X policy information from the selected PCF, and providing the V2X policy information to a base station.
Abstract:
A method for providing a vehicle-to-everything (V2X) service in a 5G mobile communication system. In accordance with an aspect of the disclosure, a method performed by a device for performing a network exposure function (NEF) in a communication system, the method comprising: receiving, from a server, a request message including request information related to service-specific information; changing data in a unified data repository (UDR) on the basis of the request message; and performing provisioning of the changed data to a user equipment (UE) via a policy control function (PCF) is provided.
Abstract:
The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof, and provides an intelligent service based on the 5G communication technology and the IoT related technology.
