Method, device and system for searching frequent reselection cell pair

Abstract

The invention discloses a method, a device and a system for searching a frequent reselection cell pair, in order to improve the efficiency of searching a frequent reselection cell. The method comprises the following steps of: when the number of frequent reselection events of a user being frequently reselected from a GSM (Global System for Mobile Communications) cell into the same TD (Time Division) cell during the present time period exceeds a first threshold, the TD cell is determined as a frequent reselection TD cell corresponding to the user; when the number of frequent reselection events of the user being frequently reselected from a TD cell into the same GSM cell during the present time period exceeds a second threshold, the GSM cell is determined as a frequent reselection GSM cell corresponding to the user; and for each frequent reselection TD cell corresponding to the user, when the counts of the user being reselected from the same adjacent frequent reselection GSM cell into the frequent reselection TD cell exceeds a third threshold, the frequent reselection TD cell and the adjacent frequent reselection GSM cell are determined as a frequent reselection cell pair.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for finding frequently reselected cell pairs. Background technique [0002] The mobile station reselects from the TD (Time Division) cell in the 3G network to the GSM (Global System of Mobile communication) cell in the 2G network or reselects from the GSM cell to the TD cell in the idle state. The process generally takes 3 to 5 seconds, and the mobile station cannot receive paging information during the reselection process of the cell (such as unable to communicate, unable to send and receive short messages); therefore, for users, if the mobile terminal frequently The reselection operation between the 2G network and the 3G network may cause the mobile terminal to frequently fail to communicate, send and receive short messages, etc., which will seriously affect the user experience of the user using the mobile terminal. Therefore, how to deal with f...

Problems solved by technology

[0006] At present, although the signaling information in the TD network can be analyzed to know the target cell frequently used in the reselection process in the TD network, the source cell used in the reselection process in the GSM network cannot be known. Therefore, network optimization personnel are performing network optimization work , it is necessary to determine all the adjacent GSM cells adjacent to the TD cell as the target cell, and adjust the parameters of each adjacent GSM cell to determine whether the network of the adjacent GSM cell needs to be optimized. Therefore, The existing method needs to consume a lot of manpower and material resources to determine the GSM cells that need to be optimized, and it is inefficient to operate a large number of GSM cells manually.
