Cell reconfiguration method, device and system, and associated equipment

Abstract

The invention discloses a cell reconfiguration method, device and system, and associated equipment. The cell reconfiguration method, device and system, and the associated equipment are used for simplifying a cell reconfiguration flow, reducing cell reconfiguration time, and reducing the overhead of physical layer resources of a reconfigured cell in a reconfiguration process. The cell reconfiguration method includes the following steps of receiving cell reconfiguration signaling sent by a network side, wherein the cell reconfiguration signaling carries wireless air interface configuration parameters; performing wireless air interface parameter configuration on a physical layer according to the wireless air interface configuration parameters; and sending feedback of cell reconfiguration completing signaling to the network side.

Description

technical field [0001] The present invention relates to the field of wireless communication technologies, and in particular, to a cell reconfiguration method, apparatus, system and related equipment. Background technique [0002] This section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] After the wireless network slicing function and virtualization function are introduced, the air interface resources of each cell will need to support dynamic allocation. The existing technology provides the following two solutions: [0004] Technical solution 1: For reconfiguration of cell-level public resources, in the existing protocol process, the SIB (Secondary System Message) can be broadcast, and the reconfiguration can be notified to the terminals in the cell in cooperation with the process of Paging (paging) in the cel...

Problems solved by technology

[0029] However, if cell reconfiguration is performed according to the above process, since the target cell is a newly configured cell, the terminal needs a long time for downlink synchronous network search to obtain system information. In addition, the random access process will also consume too many processes. The cell reconfiguration time is too long

Moreover, when cell reconfiguration occurs, due to the presence of multiple online active users, the reconfigured target cell will have a concentrated burst of multi-terminal service access processes, and physical layer resources may be in short supply in a short period of time.
