    Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of a proactive switch of vehicle-to-everything communication from a device-to-device connection to a connection routed by one or more network devices. In example embodiments, a first terminal device receives, from a second terminal device via a device-to-device connection, an indication of a decision to switch the device-to-device connection to a connection routed by at least one network device for communication with the second terminal device. Based on the received indication from the second terminal device, the first terminal device then determines proactive switching from the device-to-device connection to the routed connection to be performed. The first terminal device then sends a request to a first network device of the at least one network device to set up the routed connection, the request indicating a cause for the determined proactive switching.

    Abstract: Embodiments of the present disclosure relate to a centralized network device change procedure. A method comprises in response to a distributed network device being to be disconnected with a centralized network device and connected with a further centralized network device, transmitting an interface resuming request from a distributed network device to the further centralized network device, the interface resuming request being used for resuming an inactivated interface between the further centralized network device and the distributed network device, the terminal device is served by the centralized network device via the distributed network device; and in response to receiving, from the further centralized network device, a resuming status message indicating the interface is successfully resumed, activating the inactivated interface to complete the resume procedure. In this way, when a gNB-DU, which is located at the satellite and moves along with the satellite, moves from the coverage of a gNB-CU to the coverage of a new gNB-CU, a terminal device, which is served by a gNB-CU via a gNB-DU, will keep the connection with the gNB-CU, such that the connectivity of the accessed terminal device will be maintained and meanwhile the signalling overhead for interface configuration will be saved.

    Abstract: Methods, apparatuses and computer program products are disclosed for data distribution. A method comprises: sending a message, containing an indication of a target area related to first data to be distributed, from a first distribution unit to a distribution management device; receiving first information comprising at least one target address from the distribution management device in response to sending of the message, wherein the at least one target address is related to one or more second distribution units covering the target area; and sending the first data to the at least one target address when the message does not contain the first data.

    Abstract: Methods and apparatus, including computer program products, are provided for V2X server discovery. In some example embodiments, there may be provided a method. The method may include receiving, by a user equipment, an indication of an identity of a local server configured to provide, in the serving public land mobile network, information regarding a vehicle-based service, when the user equipment enters a region of the serving public land mobile network; and discovering, by the user equipment, the local server based on the received indication of the identity. Related systems, methods, and articles of manufacture are also disclosed.

    Abstract: Embodiments of the present disclosure relate to methods and devices for adaptive media service. In example embodiments, a base station determines a throughput estimate associated with at least one terminal device served by the base station. The base station sends an indication of the determined throughput estimate, directly or indirectly, to one of the at least one terminal device to enable the terminal device to determine, based on the determined throughput estimate, a way for processing a media segment to be received via the base station from an application server. In this way, the media service delivery may be adapted dynamically and efficiently.

    Abstract: Embodiments of the present disclosure relate to a method, a device and a computer readable medium for IPv6 address management in an IAB system. The method comprises obtaining an IPv6 prefix for an IAB node in the IAB system, the prefix being associated with the donor central unit or a donor distributed unit in the IAB system; determining an interface identity for the IAB node; and generating, based on the Internet Protocol Version 6, IPv6, prefix and the interface identity, an IPv6 address for the IAB node for communication between the donor central unit and the IAB node. As a result, IPv6 address management for an IAB node in an IAB system is implemented.
