Paging parameter self-optimizing method in long term evolution network and system thereof

Abstract

The embodiment of the invention discloses a paging parameter self-optimizing method in a long term evolution network and a system thereof. The method comprises that: an eNB monitors and counts paging loads and paging performance; the counting result of the paging loads and the paging performance obtained via counting is reported to an OAM system by the eNB according to the preset period or based on the preset event trigger; the OAM system confirms correction of paging parameters and the paging parameters needed to be adjusted according to the counting result of the paging loads and the paging performance; if the paging parameters are needed to be corrected, the OAM system adopts the preset optimization algorithm to calculate adjustment values of the paging parameters needed to be adjusted and sends a paging parameter adjustment notification message to the eNB; and the eNB adjusts the paging parameters needed to be adjusted according to the paging parameter adjustment notification message and notifies the adjusted paging parameters to a user terminal UE. Paging parameter self-optimization in the LTE network can be realized by the embodiment of the invention so that the network paging performance is effectively enhanced and artificial network optimization cost is reduced.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for self-optimizing paging parameters in a long-term evolution network. Background technique [0002] Long Term Evolution (LTE) is a new generation of wireless communication system launched by the 3rd Generation Partnership Project (3GPP). It is an evolution technology of the third generation (3G), generally referred to as 3.9G Or quasi-4G. There are currently three versions of LTE, R8, R9, and R10. Among them, the R8 and R9 versions were frozen at the end of 2008 and 2009 respectively. The R10 version representing 4G technology is also called the advanced long-term evolution technology (LTE-Advanced). The standardization work was completed in September. LTE adopts Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO) technology as the mainstream standard for its wireless network evolution. LTE R8 version can provide 100Mbit / ...

Problems solved by technology

[0008] In the process of implementing the present invention, the inventors found that LTE networks may also face paging signaling storms, and manual optimization of paging parameters involves time-consuming and labor-intensive tasks. The existing Self-Organized Network (SON) technology also Self-optimization of paging parameters is not supported, resulting in low paging performance of the LTE network and high cost of manual network optimization, so it is necessary to increase the paging self-optimization function
