The disclosed technology separates session management function signaling from the AMF. In particular, an SMF key is created for each SMF following the AMF generating an SM context request that contains gNB information and UE subscription information. Each PDU session creates a direct connection between the SMF and a local gNB. The gNB communicates with each SMF directly over a new interface (N3-C) for session management that is independent of the N2 interface used by the gNB to communicate with the AMF for mobility management. In this way, each SMF independently handles NAS signaling with the UE, using the SMF key and gNB related session-management signaling over an independent interface with the gNB. This removes the burden of relaying these communications through the AMF, which is then freed up to solely to handle mobility management signaling, resulting in an improved architecture.

Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device. The capability information may include information indicating support for an Ethernet type packet data unit session or header parameter compression. An Ethernet type packet data unit session may be instantiated based on the capability information.

There are provided measures for improved service continuity with mobile edge computing. Such measures exemplarily comprise detecting a handover of a communication endpoint from a first gateway to a second gateway, determining, whether an ongoing mobile edge computing related application session of said communication endpoint is routed by said first gateway, checking, upon positive result of said determining, whether said ongoing mobile edge computing related application session fulfills a predetermined condition, and initiating, upon positive result of said checking, a swap of said ongoing mobile edge computing related application session from said first gateway and a first mobile edge computing entity connected to said first gateway to said second gateway and a second mobile edge computing entity connected to said second gateway.

The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. A method carried out by a network data analytics function (NWDAF) device, and a device for carrying out same may be provided according to various embodiments of the present disclosure, the method comprising the steps of: acquiring, for a protocol data unit (PDU) session, traffic pattern-related information, traffic type-related information and current time-related information; determining an inactivity timer value for the PDU session on the basis of the traffic pattern-related information, traffic type-related information and current time-related information; and transmitting the inactivity timer value to a session management function (SMF) device.

In a wireless local area network (wireless LAN) system, a transmitting STA can transmit, to a receiving STA, a grouping initiation frame for generating a group that is to perform sensing. The grouping initiation frame can include information related to a session identifier (ID) for a sensing session and to the number of transmission times of a sensing signal performed in the sensing session. The transmitting STA can receive a grouping response frame from the receiving STA. The receiving STA can be included in the group on the basis of the reception of the grouping response frame from the receiving STA within a threshold time preset from the transmission time of the grouping initiation frame. The sensing session can include at least one transmission opportunity (TXOP).

According to an embodiment, a method of a user equipment (UE) in a communication system supporting an edge computing service using an edge data network including a first server providing, to the UE, first configuration information for application data traffic and a second server exchanging, with the UE, the application data traffic comprises transmitting a service provisioning request to a third server providing second configuration information for a connection with the first server and receiving, from the third server, a service provisioning response including network identification information related to a list of the first server or the second server in response to transmitting the service provisioning request.

According to an embodiment, a method of a user equipment (UE) in a communication system supporting an edge computing service using an edge data network including a first server providing, to the UE, first configuration information for application data traffic and a second server exchanging, with the UE, the application data traffic comprises transmitting a service provisioning request to a third server providing second configuration information for a connection with the first server and receiving, from the third server, a service provisioning response including network identification information related to a list of the first server or the second server in response to transmitting the service provisioning request.

A session management function (SMF) receives, from an access and mobility management function (AMF), a first request to establish a first session for a wireless device. The first request comprises a cellular internet-of-things (IoT) optimization indication for transfer of data of cellular IoT over a control plane. A second request to establish a second session between the SMF and the UPF is sent to a user plane function (UPF). The data for cellular IoT is received from the UPF via the second session. The data is sent to the AMF via the first session.
