Embodiment 1

[0092] A RACH self-optimization method disclosed in Embodiment 1 of the present invention is applicable to base stations, and the execution process of the method is divided into three network situations according to different network situations:

[0093] In the first network situation, the access parameter configuration is checked during the startup process of the base station, specifically:

[0094] When the base station is started, check the access parameter configuration of each covered cell in units of cells, if the access parameter configuration is abnormal, generate a warning message for prompting that the initialization service parameter configuration is abnormal, in the warning message Contains the location information of the abnormal access parameter configuration;

[0095] In the second network situation, during the operation of the base station, the access parameter configuration between adjacent base stations is checked and handled, specifically:

[0096] When the...

Embodiment 2

[0115] Based on the RACH self-optimization method disclosed in Embodiment 1 of the present invention, the three network conditions disclosed above will be described in detail.

[0116] For the first network situation, such as figure 1 As shown, it is a flowchart of a method for checking access parameter configuration during base station startup, which mainly includes:

[0117] S101, check the configuration parameters of each covered cell in units of cells, and judge whether the radius and high-speed flag of each cell are consistent with the physical random access channel PRACH public information configuration in the system information block SIB2, and if not, execute S102;

[0118] S102. Generate first warning information for prompting abnormal configuration of initialization service parameters, and send it to OMC;

[0119] S103. In the base station, check whether there is a conflict between the access parameters of each covered cell and an adjacent cell in units of cells, an...

Abstract

The invention provides a RACH self-optimization method, a device, a system and a base station for a LTE system. Access parameter configuration is checked during the starting procedure of the base station; conflict checking and processing are performed on access parameter configuration of adjacent base stations during the operation process of the base station; adaptive adjusting is performed on each PRACH configuration parameter based on the start-up status of an optimization switch which performs adaptive adjusting corresponding to each PRACH configuration parameter during the process of normal access to user terminals; and therefore RACH automatic optimization is realized according to continuously changing network situation.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a RACH (Random Access CHannel, Random Access Channel) self-optimization method, device, system and base station in an LTE (Long Term Evolution, Long Term Evolution) system. Background technique [0002] At present, in order to realize the autonomous function of the wireless network, a SON (Self Organization Network, self-organizing network) technology is introduced in the standardization stage of the LTE technology. 3GPP has introduced the RACH optimization module in the SON technology of the LTE project system. The RACH optimization module can adaptively adjust RACH parameters according to the operation status of the network equipment itself to optimize the performance of the entire network and ensure a good user experience. [0003] Because 3GPP-related protocols do not specify specific RACH optimization algorithms, but only specify various functions that RACH...
