    摘要： Embodiments of this application provide a node handover method and a related device. A source donor node sends a handover request message to a target donor node, where the handover request message includes context information of an IAB node and context information of at least one terminal device. The source donor node receives a handover response message sent by the target donor node, where the handover response message includes an identifier of an accepted terminal device in the at least one terminal device and/or an identifier of a rejected terminal device in the at least one terminal device. In this way, the terminal device that is in the at least one terminal device connected to the IAB node and that is accepted by the target donor node may be handed over to the target donor node, so that the IAB node and the accepted terminal device are handed over to the target donor node together, and normal transmission of data of the accepted terminal device is ensured.

    摘要： A mobility management method and apparatus are provided, to flexibly switch a forwarding path, and ensure service continuity in a movement process of a terminal device. The method includes: A control plane network element determines a changed media access control address MAC address of a first terminal device after the first terminal device moves. Then, the control plane network element determines at least one second terminal device that belongs to a same terminal device group as the first terminal device, where the first terminal device is a terminal device whose address changes after the movement, and the at least one second terminal device is a terminal device other than the first terminal device in the terminal device group. Finally, the control plane network element notifies the first terminal device and the at least one second terminal device to update to the changed MAC address of the first terminal device.

    摘要： A method and an apparatus for cell selection or reselection and a method and an apparatus for setting a cell handover parameter are provided. The method for cell selection or reselection includes: acquiring speed priorities of one or more cells and a movement speed grade of a terminal device; and performing cell selection or cell reselection according to the speed priorities and the movement speed grade. According to the embodiments of the present disclosure, the terminal device acquires speed priorities of network cells and its own movement speed grade, so as to firstly perform a cell filtering by using the speed priority and then perform another cell filtering by using a frequency priority during the cell selection to select a target cell to camp on , to enable the terminal device to distinguish between cells with different speed priorities and preferentially camp on a cell matching a movement speed of the terminal device, so that the terminal device camps on cells more efficiently and cells with different priorities serve the terminal device more efficiently.

    摘要： A radio access device includes a controller signal processing unit (RNSAP unit) that processes a signal exchanged with a radio network controller (RNC); and a switching center signal processing unit (RANAP unit) that processes a signal exchanged with a switching center. The RNSAP unit requests to establish a communication path between the radio access device and the RNC and a communication path between the RNC and a BTS by transmitting a request signal to the RNC. Subsequent to receiving an acknowledgement signal corresponding to the request signal from the RNC, the RANAP unit requests to establish a communication path between the switching center and the RNC. Subsequent to receiving, by the RANAP unit, an acknowledgement signal corresponding to the request signal from the switching center, a communication path between the radio access device and the UE is released.
