Problems solved by technology

Among them, the process of adjacent cell missing configuration and redundant configuration detection requires a lot of manpower and material resources, and the wireless environment changes over time, resulting in adjacent cell missing configuration and redundant configuration detection are often accompanied by the operation process of the entire network. The most tedious link in the process of network construction and optimization
At present, there have been a large number of attempts of auxiliary methods for neighborhood optimization, but there is no mature solution

Embodiment Construction

[0045] In the present invention, the RNC (Radio Network Controller, radio network controller) sends a message that triggers the self-optimization of the neighbor cell list to the OMC. The OMC determines whether to perform the self-optimization of the neighbor cell list according to the parameters of the neighbor cell list self-optimization, and if so, then According to the judgment result, the neighbor list self-optimization (delete neighbors or add neighbors) operation is performed on the neighbor list.

[0046] Wherein, the message that triggers the self-optimization of the neighbor cell list includes a neighbor cell deletion trigger message and a neighbor cell addition trigger message;

[0047] The self-optimized parameters of the neighbor cell list include: the neighbor cell delete trigger threshold DelNbrThreshold, the neighbor cell deleteable threshold DelNbrPermittedThreshold, the neighbor cell increase trigger threshold AddNbrThreshold, and the neighbor cell list update samp...

Abstract

The invention discloses a method and a system for self-optimizing a wireless communication network neighbor list. The method comprises that: a wireless network controller sends information for triggering neighbor list self-optimization to a network management platform; and the network management platform judges whether to self-optimize a neighbor list according to a parameter of the neighbor list self-optimization, and deletes or increases neighbors according to a judgment result if so. The method and the system effectively solve the problems of missing configuration and redundancy configuration of the neighbors, make the neighbor list automatically converge to the best state in the changeable wireless environment, and can improve the neighbor optimization efficiency, reduce the system construction cost, and improve the system switching performance.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for self-optimizing a neighboring cell list of a wireless communication network. Background technique [0002] Ensuring the service continuity of mobile users is a basic function of the wireless communication system, and the handover of the UE serving cell is the main means to ensure the service continuity. [0003] In a cellular mobile communication system, a UE (User Equipment, mobile station, or user equipment) needs to measure the radio quality of neighboring cells in order to perform a serving cell handover. Due to the limitation of UE measurement capability and measurement efficiency, the number of neighboring cells that the UE can simultaneously measure is limited (such as WCDMA (Wideband Code Division Multiple Access) / LTE (Long Term Evolution, Long Term Evolution) FDD (Frequency In the Division Duplex (Frequency Division Duplex) system, there ar...
