Embodiment Construction

[0088] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0089] Please refer to figure 1 , figure 1 It is a flowchart of a cell handover method provided by an embodiment of the present invention, including:

[0090] 101. The source cell reads the history information of the UE stored by itself, where the history information includes at least the cell identification code of at least one cell where the UE has recently camped and the residence time in the corresponding cell.

[0091] According to the description of the UE ...

Abstract

The invention discloses a cell switching method and related equipment, wherein the method includes that: a source cell reads self-stored historical information of user equipment (UE), the historical information at least including a cell identification code of at least one cell that the UE recently resides in; and the source cell identifies the switching mode of the UE according to the cell identification code and the residing time, and executes a strategy of switching in advance or a strategy of delay switching to the UE according to the switching mode. The probability of occurrence that the switching of the UE is triggered too early or too late in a cell switching process is reduced, thereby preventing problems of switching errors, switching failures, ping-pong effects and the like.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell switching method and related equipment. Background technique [0002] In a wireless communication system, user equipment (UE) needs to perform cell handover in many situations, such as UE leaving the serving cell (ie, the source cell) and moving to another cell (ie, the target cell), or the load of the serving cell is unbalanced In order to realize resource sharing, or in order to improve resource utilization when the UE does not match the service characteristics of the serving cell, cell handover is required. [0003] In the process of cell handover, the setting of handover parameters is particularly important, and the radio resource manager (Radio Resource Management, RRM) in the base station (eNB) can automatically detect and adjust dynamic parameters. However, if the handover parameters are set unreasonably, problems such as HO ping-pongs, handover fail...
