Background technology
The base station power configuration of existing mobile communication system, before network design, by professional network planning personnel, carry out emulation or calculate the initial configuration power of each base station, then by the nearly step of drive test, power optimization is carried out in base station, adjusted and cover and weak overlay area.Network is paid Hou， operator and is added up by method and the KPI of drive test by network optimization engineer, and the base station power of having installed is optimized, and improves the combination property of network.
The fast development of nearly 20 years of mobile communication process, corresponding industry is mature on the whole, but still can not meet the demand of people to mobile service, and current people are mainly reflected in mobile data services the demand of wireless traffic.Developing rapidly of this demand driving mobile broadband and the Internet, increases substantially to the demand of mobile capacity, and this demand is more than the twice of traditional fixed network capacity requirement.Under limited bandwidth, for a nearly step meets the demand of user to wireless network, dispose the trend that a large amount of base stations is future mobile communications network Development, therefore according to present network optimized approach, need to drop into a large amount of man power and materials.
Current conventional optimizing power method, the networking initial stage mainly adopts road detector to carry out signal strength measurement to weak overlay area, then by test machine, carries out network insertion, and data are optimized, by optimization data, carry out base station power optimization, increase or reduce the transmitting power of base station.In commercial stage, by analyzing the KPI data of network, analyze the interference profile of network, for crossing overlay area, reduce the power of base station.
The base station power optimization of prior art, after the quantity of base station is doubled and redoubled, need to consume a large amount of man power and materials, adopts artificial optimization to follow engineers and technicians' technical capability relevant simultaneously, therefore of low quality to the optimization of base station power.
Summary of the invention
The object of the present invention is to provide a kind of base station self-organization method, be intended to improve quality, reduction network operation cost, the raising network performance that base station power is optimized.
The present invention is achieved in that a kind of base station self-organization method comprises: the common-frequency cell signal intensity in the measurement report of statistics edge customer; The statistical value that obtains the common-frequency cell signal intensity in the measurement report of edge customer is reported to network optimization center or network management center; Setting statistical value optimization or the corresponding thresholding reporting and power adjusts interval.Concrete steps are as follows:
Common-frequency cell signal intensity in the measurement report of step 1, statistics edge customer.
In user's measurement report, homogeneous-frequency adjacent-domain signal strength signal intensity is greater than this community, supposes that this cell signal strength is Q
this, in measurement report, the strongest homogeneous-frequency adjacent-domain signal strength signal intensity is Q
adjacentif the average of the signal strength signal intensity of this Cell Edge User of long-time statistical is
, variance is σ
q 2if average and variance are greater than predefined thresholding, this website carries out power adjustment preparation, or carries out power adjustment.
Step 2, by the statistical value of the common-frequency cell signal intensity in edge user's measurement report, the average obtaining and variance are reported to network optimization center or network management center, by network optimization center or network management center, determined the power optimization of website.
Step 3, setting statistical value optimization or the corresponding thresholding reporting and power are adjusted interval.
Further, power decreasing needs the cutting off rate and the handover success rate that with reference to weak covering, cause.
Further, for the measurement report information before switching, in these information, require the signal strength signal intensity that at least exists to be greater than this community with neighbor cell signal intensity frequently.
Further, for guarantee that website power adjusts according to reliably, the statistical information sample of collection is abundant.
effect gathers
