The present invention relates to management of mobility of a terminal in a wireless communication system, and an operating method of the terminal comprises: a step of transmitting a first message requesting mobility-related capability information of an access network, and a step of receiving a second message informing of the mobility-related capability information of the access network. In addition, the present invention includes other embodiments in addition to the aforementioned embodiment.
Abstract:
A method for selecting a source address in a host electronic device is provided. The method includes determining an address type to use in communication of an application which is being executed, selecting a source address based on the determined address type, and setting the selected source address as a source Internet Protocol (IP) address for a transmission packet of the application which is being executed.
Abstract:
A method for generating a key hierarchy by a MS in a wireless network is provided. The method includes transmitting an authentication request message to a new BS, receiving an authentication response message as a response message to the authentication request message from the new BS, determining whether to perform a full authentication operation with a H3A server based on the authentication response message, performing the full authentication operation or a crypto-handshake operation with the H3A server based on the determining result, after performing the full authentication operation or the crypto-handshake operation, determining whether a first expected signature value received from the new BS is identical to a first expected signature value calculated by the MS, and if the first expected signature value received from the new BS is equal to a first expected signature value calculated by the MS, determining that an authentication for the new BS has succeeded.
Abstract:
A method and apparatus for performing Transmission Control Protocol (TCP) communication at a network node in a wireless communication system are provided. The method includes receiving, by the network node that controls a connection between a Mobile Station (MS) and a data network, a TCP KeepAlive packet for maintaining a TCP connection established between a correspondent node and the MS through the data network from the correspondent node, determining whether the MS is in an idle mode in response to the reception of the TCP KeepAlive packet by the network node, if the MS is in the idle mode, transmitting an acknowledgement packet in response to the TCP KeepAlive packet to the correspondent node by the network node, and transmitting indication information indicating the reception of the TCP KeepAlive packet to the MS by the network node.
Abstract:
The present disclosure relates to a 5G or a pre-5G communication system to be provided in order to support a higher data transmission rate than a 4G communication system such as LTE. The present invention provides a method for receiving, by a terminal, a mobile end service in a communication system, the method including: a step of ascertaining whether there exists a continuously available service among services which have been provided from a serving base station, on the basis of a list of supported services received from a target base station; and in the case that there exists a continuously available service, a step of transmitting a service area update request to the target base station via a connection layer if the continuously available service supports a mobile end service.
Abstract:
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for managing congestion in a first node in a wireless communication system is provided. The method includes receiving status information from each of nodes configuring a network with the first node, receiving information about a service requirement criterion from a second node as one of the nodes, acquiring additional path setup information for the second node based on the status information received from each of the nodes and the information about the service requirement criterion received from the second node, and transmitting the acquired additional path setup information to the second node.
Abstract:
The present disclosure relates to a communication method and a system for 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 present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as a smart home, a smart building, a smart city, a smart car, a connected car, health care, digital education, a smart retail, and security and safety services. A method and an apparatus for communicating voice calls in a communication system are provided. The apparatus includes a first terminal that is a representative terminal configured to receive a voice call sets up a function for using a call forwarding service with a second terminal that is an auxiliary terminal, when the first terminal detects an occurrence of an event complying with a certain criterion for performing a call forwarding service, to determine whether a call forwarding service with the second terminal is being executed, and to execute, unless the call forwarding service is being executed, the call forwarding service and to transfer a voice call received by the first terminal to the second terminal.
Abstract:
A method for transmitting a status report in a communication system based on multiple Radio Access Technologies (RATs) is provided. The method includes, when missing sequence numbers are detected from sequence numbers of packets stored in a reception buffer, identifying whether there are one or more sequence numbers which have not been received due to a transmission delay time difference between the multiple RATs in the missing sequence numbers, and when there are one or more sequence numbers in the missing sequence numbers, delaying transmission of the status report.
Abstract:
An apparatus and a method for access authentication of a mobile station in a wireless communication system are provided. The method includes receiving a session certificate for the access authentication from a core network, transmitting the session certificate to a new access network during a handover to the new access network, and receiving an authentication result based on the session certificate from the new access network.
Abstract:
A method and a device for managing mobility of a mobile station in an Internet Protocol (IP) based network are provided. The method includes receiving a request for allocation of an IP address from an application, determining a type of IP address to be allocated to the application based on the request for the allocation of the IP address, and allocating the determined type of IP address to the application.
