Ping-pong reselection control method, device and system

Abstract

The embodiment of the invention discloses a ping-pong reselection control method, a ping-pong reselection control device and a ping-pong reselection control system. The ping-pong reselection control method comprises the following steps of: monitoring whether user equipment (UE) subjected to ping-pong reselection exists in the femtocell coverage area or not, if so, performing the ping-pong reselection control, namely adjusting a cell reselection parameter of the femtocell, and/or refusing the residence of the UE subjected to the ping-pong reselection in the femtocell. In the technical scheme provided by the embodiment of the invention, whether the UE is under the ping-pong reselection condition or not is judged according to the frequency of position update of the UE, and for the UE under the ping-pong reselection condition, the circumstance of the ping-pong reselection of the UE in the femtocell coverage area is reduced or avoided by modifying the position update parameter or refusing the residence of the UE in the femtocell. Therefore, insignificant processes and signaling interaction caused by the ping-pong reselection are reduced and the power consumption of the UE is decreased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for controlling ping-pong reselection. Background technique [0002] Femtocell base station femtocell (also known as desktop base station) is an ultra-miniature mobile access point launched in recent years according to the development of 3G and the trend of mobile broadband. It is a home base station technology, mainly used to solve the problem of home indoor coverage. Running on the IP protocol and accessing the operator's mobile core network through the user's IP broadband network, it presents innovative features such as ultra-miniaturization and plug-and-play. [0003] Femtocell uses the IP protocol, and is connected through broadband circuits such as ADSL (Asymmetrical Digital Subscriber Loop) and LAN (Local Area Network) that the user already has. Unicom. [0004] Femtocell is applicable to various standards such as CDMA (Code Division Mu...

AI Technical Summary

Problems solved by technology

When femtocell is used for coverage, since femtocell is mainly used in indoor and home environments, the UE's mobility is not strong and the moving speed is slow in such environments

Within a certain period of time, the UE is always in the overlapping area of ​​the femtocell and the macro cell network or in the edge coverage area of ​​the femtocell. In these areas, the signal fluctuates greatly. Compared wi
