Disclosed is a user equipment for satellite communication, comprising one or more processing circuits configured to execute the following operations: evaluating a transmission power requirement for a user equipment to communicate with a satellite; and assisting, via an auxiliary device, the user equipment in executing at least part of the communication with the satellite when the transmission power constraint of the user equipment fails to meet the transmission power requirement, wherein the processing circuits are further configured to acquire, via the satellite, a communication mode to be switched to, and the processing circuits transmit, to the satellite, a notification indicating that a current communication mode needs to be switched, with the notification comprising information indicating the need to switch to a communication mode that meets the transmission power requirement.

In order to prevent deterioration of QoE of a user in intersystem handover, an apparatus according to the present invention includes: an information obtaining unit configured to obtain network slice related information related to a network slice used by a terminal apparatus in a first radio communication system; and a first communication processing unit configured to transmit, to a second network node of a second radio communication system, a message for intersystem handover of the terminal apparatus from the first radio communication system to the second radio communication system, the message including the network slice related information.

This application provides a server switching method and apparatus, and a communications system. The method includes: receiving, by a terminal, a first notification message, where the first notification message includes an address of a second server; sending, by the terminal, to-be-sent service data to a first server and the second server based on the first notification message; receiving, by the terminal, downlink data from the first server; obtaining, by the terminal, data processing indication information; when obtaining the data processing indication information, sending, by the terminal, the to-be-sent service data to the second server; and receiving, by the terminal, downlink data from the second server. The server switching method and apparatus, and the communications system in the embodiments of this application can implement seamless switching, ensure service continuity, avoid service interruption caused when a terminal switches between servers, and help meet an end-to-end latency requirement.

A user equipment (“UE”) can receive a request for UE mobility history information from a network node. The UE can generate a UE mobility history report. The UE mobility history report can include at least one of transitions between an inactive state and a connected state for each cell included in the UE mobility history report or a carrier frequency of each cell included in the UE mobility history report. The UE can transmit the UE mobility history report to the network node.

The present invention relates to a method for operating a service application entity (100) configured to provide a service to a mobile entity (10) in a mobile communications network based on a client session, the method comprising: —determining a context information which comprises at least information required by another service application entity (400) providing the same type of service to continue the client session with the mobile entity, —pushing the context information towards a radio access node (300) of the mobile communications network to which the mobile entity is currently connected.

A method, system, and apparatus for optimizing a connection of a station (STA) in a mesh network of a plurality of 802.11 access points (APs) carried out by a client steering daemon (CSD) running on an AP of the plurality of APs. The CSD may calculate a cost ratio based on a plurality of metrics from a list and compare the signal strength information against a predetermined value. Based on the outcome of the signal strength comparison the CSD may analyze risk for the STA, determine a course of action for the STA based on the calculating, comparing, and analyzing and send instructions to a plurality of CSDs running on each of the plurality of APs for the course of action. The course of action may be keeping a STA associated with a current interface, guiding a STA to a destination interface, or kicking a STA to a destination interface.

The disclosed technology is directed towards preventing a handover of a Wi-Fi call to a Fifth Generation (5G) standalone cellular network. In one alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device. In another alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device and the mobile device is connected to a Wi-Fi network, which facilitates camping on a 5G standalone network when the mobile device is not connected to a Wi-Fi network. In yet another alternative, a 5G standalone usage setting is disabled on a mobile device when an evolved packet data gateway (ePDG) tunnel is set up on the mobile device, which similarly facilitates camping on a 5G standalone network when the ePDG tunnel is torn down.
