Technical field
The present invention relates to communication technical field, particularly relate to a kind of strong jamming cell determination method and device.
Background technology
In the network planning, it is thus necessary to determine that the strong jamming community of community, determine that the major programme of interfered cell is as follows at present:
Application number is in the technical scheme of 200910238638.3, using the ratio I/C of the power I of the interfered cell of drive test point and the power C of main Serving cell as basic index, add up the basic index of each drive test point, calculate the power of same main Serving cell and same interfered cell ratio and interference value as this main Serving cell Yu the minizone of this interfered cell, judge, according to the size of interference value, the intensity that minizone interferes.

In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
In first embodiment of the invention, as it is shown in figure 1, the method detailed flow process carrying out determining strong jamming community is as follows:
Step 101: measure the signal intensity of the main plot obtaining each drive test point and the signal intensity of the adjacent cell of this main plot.
Preferably, measuring the signal intensity obtained is actual received power value.
In being embodied as, reality is measured the signal intensity of main plot obtained and the signal intensity of adjacent cell is loaded into internal memory, judge that whether data form is correct, then the signal strength values of adjacent cell is sorted successively according to order from high to low, the data after sequence are stored in new file.
Step 102: travel through each drive test point, according to the signal intensity of main plot of this drive test point, the signal intensity of the adjacent cell of this main plot and default signal strength threshold value, it is determined that the overlapping degree of covering between this main plot with this adjacent cell.
Preferably, for arbitrary drive test point, determine that the signal intensity of adjacent cell of main plot is more than default signal strength threshold value, and when determining the difference of the signal intensity of this main plot and the signal intensity of this adjacent cell less than default switching band threshold value, determine the overlapping coverage cell that this adjacent cell is this main plot, the overlapping degree of covering between this main plot with this adjacent cell is increased by 1;
Travel through each drive test point, obtain the overlapping degree of covering between this main plot with this adjacent cell.
Such as, the main plot of drive test point 1 is community 1, adjacent cell is community 2, the signal intensity of the adjacent cell 2 obtained is measured more than default signal strength threshold value at drive test point 1, and measure the signal intensity of the main plot 1 the obtained difference with the signal intensity of adjacent cell 2 less than default switching band threshold value at drive test point 1, then for the overlapping coverage cell that drive test point 1 adjacent cell 2 is main plot 1, then the overlapping degree of covering between main plot 1 with adjacent cell 2 is 1; The main plot of drive test point 2 is community 1, adjacent cell Ye Wei community 2, the signal intensity of the adjacent cell 2 obtained is measured more than default signal strength threshold value at drive test point 2, and measure the signal intensity of the main plot 1 the obtained difference with the signal intensity of adjacent cell 2 less than default switching band threshold value at drive test point 2, then for the overlapping coverage cell that drive test point 2 adjacent cell 2 is main plot 1, then the overlapping degree of covering between main plot 1 with adjacent cell 2 increases by 1, is 2.
