Embodiment 1

[0097] For the process of automatic flipping, please refer to image 3 As shown, the specific steps are as follows:

[0098] Step 301: The operation and maintenance center formulates and issues a measurement plan.

[0099]Step 302: The user equipment and the base transceiver station respectively perform downlink and uplink measurements and report to the BSC, and the BSC automatically changes the BAlist periodically.

[0100] Step 303: The BSC preprocesses the measurement data to obtain statistics on the FEP data.

[0101] Step 304: The operation and maintenance center stores the measurement results of multiple time periods in the area and outputs them to the system master station.

[0102] Step 305: the system master station determines the interference matrix according to the FEP data, and uses the genetic algorithm to determine the optimal frequency optimization scheme.

[0103] Step 306: the system master sends the optimal frequency optimization scheme to the BSC, and ins...

Abstract

The invention discloses a method and device for automatic replanning frequency. The method comprises the steps: executing the measurement of a link and obtaining measure data; preprocessing the measure data, and obtaining the statistics of FEP data, and building an interference matrix; according to the interference matrix, making a frequency optimization scheme; and according to the frequency optimization scheme, correcting the frequency, and performing the frequency planning to the whole network frequency point. Through the method for the automatic replanning frequency, the more accurate interference matrix is built without blocking the network, the measure data of the neighboring region can be rapidly and automatically collected without the manual intervention data collection process, and the efficiency of the current replanning frequency work can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and device for automatic frequency flipping. Background technique [0002] Traditional NOKIA system frequency optimization mainly relies on the DAC&CF (Defined Adjacent Cell&Channel Finder,) data extracted from the BSC (Base Station Controller, Base Station Controller) side to establish an interference matrix for frequency optimization. This optimization method has the following defects : [0003] (1) The degree of automation of wireless network planning and optimization is low. Since the measurement data reported daily by MS (Mobile Station, mobile station) is limited to the BAlist in the neighboring cell, it wants to reflect the BCCH (Broadcast Control Channel, broadcast control channel) of the entire network. Channel) frequency points interfere with a certain cell, you need to manually add measurement frequency points to the BAlist; [0004] (2) T...
