A communication method in a wireless communication system supporting device-to-device (D2D) communication is provided. The communication method includes transmitting a first message including information for identifying a relay to discover a relay user equipment (UE) that performs a relay function in the D2D communication, and receiving a second message including information about the relay UE that performs the relay function, from the relay UE that has received the first message, the second message being transmitted in response to the first message.

Communication method and apparatus in wireless communication system supporting D2D communication

The present disclosure provides a method whereby a mobility management entity (MME) in a cellular communication system transmits uplink data, the method comprising: receiving uplink data from a terminal; determining if the received uplink data is an Internet Protocol (IP) packet by examining the uplink data; transmitting the uplink data to a destination node via a packet data network (PDN) if the uplink data is an IP packet; and transmitting the uplink data to the destination node via a service capability exposure function (SCEF) if the uplink data is not an IP packet, wherein the uplink data comprises an indicator for indicating whether the uplink data is an IP packet.

Method for transmitting data in CIoT system and device therefor

Embodiments herein provide methods and systems for performing paging operation in 5G communication networks. The 5G core network can transmit a NAS message to a UE through a N3GPP access network, if the UE is reachable through the N3GPP access network. The NAS message can be sent by the 5G core network to the N3IWF. The N3IWF can send the NAS message to the UE, through the N3GPP access network. The UE can send a service request over 3GPP access, in response to the NAS message, to the 5G core network, through a 5G RAN. If the UE is not having access to the 5G RAN, then the UE can transmit a notification response message to the 5G core network, indicating the inability to transmit a service request. The transmission of NAS message through the N3IWF can lead to a significant saving of radio resources.

Methods and systems for performing paging operations in a 5G network

Disclosed is a method by which a first terminal supports vehicle-to-everything (V2X) communication through a first data transmission, comprising the steps of: determining a wireless resource for a second data transmission of a second terminal; transmitting, to the second terminal, first data including information of the wireless resource; and receiving, by using the wireless resource, second data transmitted from the second terminal.

V2V interaction/V2IOT communication method and device

The present invention is a method for transmitting a data packet by a user terminal in a mobile communication system. The method enters a power saving mode for transmitting the data packet only if a channel state satisfies a transmission threshold value, compares the index indicating the channel state and the transmission threshold value upon occurrence of a data packet to be transmitted, starts transmission of the data packet if the index indicating the channel state is greater than the transmission threshold value, and proceeds with the transmission of the data packet until the time set by the timer that starts at the same time as the transmission of the data packet expires.

Apparatus and method for transceiving data by user terminal

Disclosed is a method for web-based real-time communication by a user equipment (UE), including transmitting, to a web server, a message requesting information about an Internet protocol multimedia subsystem (IMS) network to which the UE is to access, receiving, from the web server, address information of the IMS network to which the UE is to access, in response to the transmitted message, when receiving, from the web server, an instruction to hold establishment of a bearer for a web-based real-time data service, restricting transmission of a signaling message for the web-based real-time data service until the bearer is established, and when sensing establishment of the bearer, transmitting, to an access point of the IMS network, at least one subsequent signaling message for the web-based real-time data service through the bearer.

Method and apparatus for providing quality of service for web-based real-time communication

A method for establishing a plurality of protocol data unit (PDU) sessions between a user equipment (UE) and a data network (DN) by the UE may comprise transmitting a message to establish the plurality of PDU sessions to at least one network function (NF) of a plurality of NFs, exchanging a signal to establish the plurality of PDU sessions among the UE, a radio access network (RAN), and the plurality of NFs based on the message, and establishing the plurality of PDU sessions between the UE and the DN according to predetermined priority and based on the signal, wherein each of the plurality of PDU sessions corresponds to a network slice (NS) for a particular service, wherein the message includes information about the particular service corresponding to the plurality of PDU sessions, and wherein the priority is determined based on the information about the particular service.

Method for establishing protocol data unit session in communication system

A method for providing a multimedia broadcast/multicast service (MBMS) to a terminal related to a vehicle by a broadcast and multicast service center (BM-SC) is provided. The method includes identifying at least one candidate service area that the terminal is predicted to pass through, and transmitting, to an MBMS-gateway (MBMS-GW), a request for configuring the radio bearer of the at least one candidate service area.

Methods and apparatuses for supporting wireless communication of vehicle

A method of a terminal for performing communication is provided. The method includes, transmitting, by a terminal located outside a cell coverage area, a request message requesting monitoring of a temporary mobile group identity (TMGI) to a relay terminal located within the cell coverage area, receiving a monitoring response message including a layer-2 group identification (ID) in a proximity-based service from the relay terminal, receiving a TMGI announcement message including the layer-2 group ID from the relay terminal, when the relay terminal detects the TMGI, and receiving data related to the TMGI by using the layer-2 group ID.

Method and apparatus for performing communication in wireless communication system

Embodiments of the inventive concept herein provide a method and User Equipment (UE) for handling PLMN selection involving Proximity Based Services (ProSe) communication. The method includes detecting one of a PLMN selection due to the ProSe communication followed by a manual Closed Subscriber Group (CSG) cell selection, and a manual CSG cell selection followed by the PLMN selection due to the ProSe communication, when the UE has stored a duplicate value of a Registered PLMN (RPLMN) and a duplicate of a PLMN selection mode. Further, the method includes preserving the stored duplicate value of the RPLMN and a stored duplicate of the PLMN selection mode.

User equipment and method for handling public land mobile network selection involving prose communication

A method and an apparatus reduce overhead for data integrity checks in a wireless communication system. When receiving a message, a first Integrity Check Value (ICV) is compared with a second ICV to detect an integrity error in the message. When the integrity error exists in the message, a frequency of the integrity error is counted. When the frequency of the integrity error is more than a threshold, a key update procedure is performed. Therefore, the overhead of the information for integrity check may be reduced in the wireless communication system.

Method and apparatus for reducing overhead for integrity check of data in wireless communication system

Disclosed is a fifth generation (5G) or pre-5G communication system for supporting higher data transmission rates beyond fourth generation (4G) communication systems such as LTE systems. A data communication method includes receiving information about a reception rate of a signal from a second user equipment (UE) performing device-to-device (D2D) communication with a first UE, receiving location information about at least one of the first UE and the second UE, determining a data communication configuration for the D2D communication based on the reception rate information and the location information, and transmitting the determined data communication configuration to at least one of the first UE and the second UE.
