Problems solved by technology

[0006] Embodiments of the present invention provide a method and device for inter-cell handover, which is used to solve the problem in the prior art that the movement trajectory of a single user can only be suppressed by using a penalty list after ping-pong handover occurs. The efficiency of ping-pong handover is low, and it is impossible to suppress ping-pong handover for other users in the cell

Embodiment Construction

[0058] The embodiment of the present invention designs a method and device for inter-cell handover. By recording the historical handover data of the user equipment accessed in the cell, the cell's handover threshold for a neighboring cell (also called is the initial handover boundary), and the initial handover boundary is fitted and smoothed to obtain the approximate straight line handover boundary of the cell for the adjacent cell, and based on this straight line and the initial handover boundary, the cell is generated for the adjacent cell The ping-pong handover suppression area (also referred to as the ping-pong handover suppression zone). Determine whether the user equipment can perform handover, thereby effectively preventing the phenomenon of user equipment ping-pong handover between cells, and based on the ping-pong handover suppression area, the ping-pong handover of all user equipment can be effectively suppressed based on the cell level, and the ping-pong handover is ...

Abstract

The present invention discloses a method for switching between cells and a device thereof for improving the suppression efficiency of user equipment ping-pong handover. The method comprises the steps that a station determines the initial switch boundary of a local jurisdiction first cell to an adjacent second cell, the initial switch boundary is subjected to adaptive smoothing processing to obtain an adaptive switch boundary, based on the adaptive switch boundary and the initial switch boundary, the switch inhibition area of the first cell for the second cell is determined, and after the message that the request sent by the user equipment in the first cell is switched to the second cell, when the user equipment in the first cell is in the switch inhibition area of the first cell for the second cell, the switch of the user equipment in the first cell to the second cell is not allowed. In this way, the phenomenon of the user equipment ping-pong handover between cells can be effectively prevented, the ping-pong handover of all equipment can be effectively inhibited based on a cell level, and the ping-pong handover suppression efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for handover between cells. Background technique [0002] In a Long Term Evolution (LTE) communication system, when user equipment moves at the edge of multiple cells, a large number of ping-pong handovers will occur due to unstable edge signal coverage. Switching back and forth between accesses will result in rate reduction and signaling waste, and will increase the risk of the user equipment being dropped. [0003] In the process of inter-cell handover, the base station configures the required measurement parameters for the accessed user equipment through the radio resource control (Radio Resource Control, RRC) connection reconfiguration message according to the handover policy, and the user equipment is performing measurement and smoothing the results Afterwards, the protocol measurement value and the physical cell ID (PCI) are reported to t...
