Problems solved by technology

In the prior art, each terminal device schedules the information (for example, handover message) of switching cells through signaling. When a large number of terminal devices need to be switched, a signaling storm will be formed. In a situation where control signaling resources are limited In some cases, it will lead to handover delay or even communication interruption

Embodiment approach

[0245] In another implementation manner, the information C includes two pieces of dedicated information, and the two pieces of dedicated information correspond to the terminal equipment A and the terminal equipment B respectively. The specific information of the terminal device A is the information of the terminal device A used for switching cells, and the specific information of the terminal device B is the information of the terminal device B used for switching cells. The cell switching information of terminal device A and the cell switching information of terminal device B are carried on resource #1 in one or more forms of code division multiplexing, frequency division multiplexing or time division multiplexing.

[0246] For example, the cell switching information of terminal device A and the cell switching information of terminal device B are carried on resource #1 in the form of code division multiplexing, and terminal device A receives the symbol on resource #1, multiplie...

Abstract

The invention provides a method for group switching. The method comprises the steps that a first terminal device receives first information from a first network device, wherein the first information is used for indicating a first resource, the first resource is used for bearing fourth information, the fourth information is information of a plurality of terminal devices for switching cells and the first terminal device is one of the plurality of terminal devices; and the first terminal device receives the fourth information on the first resource. Signaling overhead caused by cell switching of a plurality of users can be reduced, and the resource utilization rate is improved.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a method and device for group handover. Background technique [0002] In the traditional handover process of the mobile communication system, when the terminal equipment is in the connected state, the mobility management of the terminal equipment is controlled by the connected network equipment, that is, the network equipment sends a handover message to the terminal equipment to instruct the terminal equipment to The cell to be handed over to and how to perform the handover. With the development of communication technology, the coverage area of ​​a cell may increase exponentially (for example, a cell with satellites as network equipment, a cell with beamforming technology, etc.), and the number of terminal devices served by a cell is also very large. At the same time, a large number of terminal devices may need to switch cells. In the prior art, each terminal device...
