Embodiments of this application provide a session processing method and apparatus. When a quantity of sessions of a terminal device that each have an activated user plane connection is not less than a quantity threshold, the terminal device determines to deactivate a user plane connection of at least one first session, where the sessions that each have the activated user plane connection include the at least one first session. The terminal device sends a first request message to a first network element, where the first request message includes indication information, and the indication information indicates to deactivate the user plane connection of the at least one first session.

Disclosed herein are a method for tracking area update in a wireless communication system and an apparatus therefor. Specifically, a method for user equipment (UE) to perform a tracking area update (TAU) procedure in a wireless communication system comprises: a step of transmitting a TAU request message to a mobility management entity (MME); and a step of receiving a TAU accept message from the MME, wherein if the UE uses signaling optimization to enable the delivery of user data through a control plane over the MME, and the UE does not have pending user data to be transmitted through a user plane and has pending user data to be transmitted through the control plane over the MME, then a first active flag can be set in the TAU request message.

In a 6G network, microservices can be utilized in the absence of a core network. For example, after a mobile device has authenticated, through its carrier network, with a transport service layer, microservices can be allocated to the mobile device without having to be transmitted via the core network. Thus, removing the core network from the process can generate a direct line of microservices from the transport layer to the end-user. Furthermore, additional microservices and/or resources can be access through a microservices library. Consequently, packets can be securely transmitted be a wireless network facilitating sending packet profile data from one to many node devices in anticipation of the packet traversing the various node devices.

Apparatuses, methods, and systems are disclosed for indicating a packet data unit session as unavailable. One apparatus includes a processor that determines that at least one packet data unit session is unavailable. The apparatus includes a transmitter that transmits information indicating that the at least one packet data unit session is to be released.

A user device (UE) for managing radio bearers communicates, with a first base station over a first radio bearer associated with a dedicated control channel and configured to carry at least application-layer measurement reporting information, the radio bearer associated with a logical channel identity (2502); receives, from a radio access network (RAN) including the first base station and a second base station, a message related to (i) the first radio bearer or (ii) a second radio bearer having the logical channel identity and terminated at the second base station (2504); and release or reconfigure the first radio bearer in response to the message (2506).

A terminal first connects to a 5th generation (5G) standalone (SA) network and initiates a call to another terminal by using a Voice over New Radio (VoNR) technology. When the terminal fails to call the other terminal, the terminal disconnects from the 5G SA network, connects to a Long-Term Evolution (LTE) network, and then automatically initiates a call to the other terminal by using a Voice over LTE (VoLTE) technology.

This application discloses a Wi-Fi control method and apparatus and an electronic device. The method includes: receiving a Wi-Fi disconnect request message; sending, in response to the Wi-Fi disconnect request message, a notification message to a target network device, where the notification message indicates that a VoWiFi de-registration operation has been completed and that an internet key exchange IKE connection has been disconnected; and performing, in a case that a response message for responding to the notification message is received, control to disconnect from Wi-Fi.

A disclosure of the present specification provides a screen display method by a user equipment (UE). The method may comprise the steps of displaying, on a screen, information indicating that a protocol data unit (PDU) session is scheduled to be re-established, on the basis of a deactivation procedure or a release procedure of the PDU session having been performed; and when the PDU session is established, displaying, on the screen, information indicating the existence of the PDU session.
