[0037] Step A1: The terminal reports a measurement event report to the source base station.

[0038] Step A2: After the source base station receives the measurement report event, it determines to migrate the terminal to the target cell according to the handover algorithm. The source base station constructs a handover request message and sends it to the target base station where the target cell is located through the X2 interface or S1 interface. The handover request message The terminal history information is carried in the terminal history information. The historical cell information contained in the terminal historical information not only includes the cell global identifier of the historical cell, the cell type and the time length of the terminal in the corresponding historical cell, but also includes the historical cell information.

Abstract

The invention discloses a method, a device and a system for performing processing by using terminal history information. In the scheme, PCI or PCT and frequency point information of a history cell is / are added in the terminal history information, thus, a base station can acquire the PCI or PCT and frequency point information of the history cell where a terminal resides according to the terminal history information carried in switching request message after receiving the switching request message so as to perform PCT related processing according to the PCI of the history cell. Therefore, the base station fully acquires the PCI of peripheral cells of a service cell of the base station through the PCI contained in the terminal history information so as to completely collect the PCI acquired by the base station and used by the peripheral cells as much as possible and improve the success rate that the base station in the dense coverage area automatically configures the PCI by adopting a distributed method. The PCI can be modified in advance by judging the potential cells with PCI conflict to reduce the probability of the PCI conflict between the cells so as to reduce the dropped call rate and improve the switching success rate.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and system for processing terminal history information. Background technique [0002] When the mobile communication technology develops to the Long Term Evolution (LTE, Long Term Evolution) stage, there will be many evolved base stations (eNB, E-UTRAN NodeB). For such a large number of eNBs, if the traditional manual maintenance method is adopted, the workload of installation, configuration, and maintenance will be huge, and the cost will be very high. In the current situation where the cost of operation and maintenance is getting more and more attention, the self-organizing network ( SON, Self Organizing Network) concept. The so-called SON is a mobile communication network that can provide automatic installation, configuration, maintenance and other functions to reduce the workload of manual maintenance, thereby greatly reducing the cost of operation...
