Abstract
Embodiments of the present application provide a management method, device and storage medium for cell handover. When the terminal device needs to be handed over from a source cell to another cell, a network device in the source cell determines, according to reference clock information received from a designated node, a target cell that meets a preset condition, and further, hands over the terminal device from the source cell to the target cell, where the preset condition may be a preset condition meeting TSN or TSC clock requirements; in other words, when the target cell meets the TSN or TSC clock requirements, the terminal device can be handed over from the source cell to the target cell.
Claims20
A method for cell handover, comprising:
- sending, by a source network device, a handover request to a candidate device that corresponds to a candidate cell, the handover request including a clock-accuracy requirement of a service associated with a terminal device;
- receiving, by the source network device, handover response information from the candidate device, the handover response information indicating whether the candidate cell satisfies the clock-accuracy requirement, and, on a condition that the clock-accuracy requirement is satisfied, including reference clock information of the candidate cell;
- determining, by the source network device, according to the reference clock information, a target cell based on a clock accuracy of the target cell;
- and
- initiating a handover of a terminal device from a source cell to the target cell.
A method for cell handover, comprising:
- receiving, by a candidate device corresponding to a candidate cell, a handover request from a source network device, the handover request including a clock-accuracy requirement of a service associated with a terminal device;
- evaluating, by the candidate device, whether a clock accuracy of the candidate cell satisfies the clock-accuracy requirement;
- on a condition that the clock-accuracy requirement is satisfied, sending, by the candidate device, handover response information comprising an acknowledgement and reference clock information of the candidate cell to the source network device;
- and
- on a condition that the clock-accuracy requirement is not satisfied, sending, by the candidate device, handover response information indicating a negative acknowledgement;
- wherein the reference clock information is used for the source network device to determine a target cell based on a clock accuracy of the target cell and initiate a handover of the terminal device from a source cell to the target cell.
A source network device, comprising:
- a processor, a memory and a communication interface;
- wherein
- the memory stores computer-executable instructions;
- the processor executes the computer-executable instructions stored in the memory, causing the source network device to:
- send a handover request to a candidate device that corresponds to a candidate cell, the handover request including a clock-accuracy requirement of a service associated with a terminal device;
- receive handover response information from the candidate device, the handover response information indicating whether the candidate cell satisfies the clock-accuracy requirement, and, on a condition that the clock-accuracy requirement is satisfied, include reference clock information of the candidate cell;
- determine, according to the reference clock information, a target cell based on a clock accuracy of the target cell;
- and
- initiate a handover of a terminal device from a source cell to the target cell.
