Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing a connection relationship between a coverage management system and a communication network according to the present invention, and will be described with reference to FIG. 2 showing a configuration of a coverage management system.

As shown in the figure, the coverage management system 100 is connected to the mobile communication network and the wired communication network to check the coverage state of the mobile communication network to determine whether a hall area, which is a shadow area, occurs in the coverage area, The sector orientation of the base station corresponding to the main beam is moved or the sector orientation of the base station corresponding to the sub-beam is moved so that the area of each base station antenna pattern in the hole area can be balanced .

In addition, the coverage management system 100 is connected to the operator terminal 200, and provides the operator with information related to the operation performed on the coverage management system 100 in real time.

The coverage management system 100 includes a Web server 300, a hole removal operation processing server 400, a simulation execution management server 500, and a simulation execution server 610.

First, the simulation execution management server 500 performs a simulation for grasping coverage of a specific area mobile communication network.

The simulation execution server 610 includes a GIS map database 630 for storing GIS (Geographic Information System) data and an antenna configuration database 650 for storing antenna configuration information. Accordingly, the coverage of the specific area mobile communication network is grasped based on the GIS data and the antenna shape information.

The hole removal operation processing server 400 calculates the area of the area occupied by the base station antenna pattern in the hole area (shaded area) from the coverage information of the mobile communication network detected by the simulation execution server 610, The base station corresponding to the sub beam is identified and the beam is adjusted according to the situation in the hole area to balance the area of the base station antenna pattern in the hole area.

3, when the antenna pattern area of the base station is overlapped within the hole area, the hole removal operation processing server 400 deletes the hole pattern of the base station in the hole area operation processing server 400, The base station corresponding to the main beam having the maximum number of main beams (Max_Main_Beam) set in the order of the area occupied by the antenna pattern is set, and the sector orientation of the sub-beam base station excluding the main beam in the hole area is set at the center of the hole Moves in the direction away.

Here, the hole removal operation processing server 400 moves the sector orientation of the sub-beam base station to the maximum movable orientation angle (Max_Ori_Step) when moving in the direction away from the hole center, ). The Unit_Step (predetermined unit) means an orientation angle that can be moved at a time, and can be changed according to the operator's needs.

At this time, the hole removal operation processing server 400 moves within the range where the orientation of the sub beam does not completely deviate from the hole area.

In addition, the hole removal operation processing server 400 may change the orientation of the adjacent base station in the sub beam direction (for example, when the sector orientation of the sub-beam base station is shifted (e.g., the sub beam moves by the limit angle (Beam_Ori_Limit) (Nei_Beam_Step) of a predetermined adjacent base station, thereby preventing a hole region, which may be additionally generated, from being generated as the sub beam moves.

4, when there is no main beam from the base station in the hole area, the hole removal operation processing server 400 determines that the area occupied by the base station antenna pattern in the hole area is a predetermined number And moves the main beam orientation in the hole region toward the hole center point.

For example, the base station of the antenna occupying the largest area in the hole area is selected as the main beam.

The beam adjusting unit 450 shifts the sector orientation of the base station corresponding to the main beam or the sector orientation of the base station corresponding to the sub beam according to the situation in the hole region so that the area of each base station antenna pattern in the hole region is balanced.
3, when the antenna pattern area of the base station is overlapped in the hole area, the beam adjustment unit 450 adjusts the sector orientation of the sub-beam base station excluding the main beam in the hole area from the center of the hole Moves in the direction away.
Here, when the sector orientation of the sub-beam base station moves in the direction away from the hole center, the beam adjusting unit 450 moves to the maximum orientable angle (Max_Ori_Step), and moves to a predetermined unit (Unit_Step) do.
4, the beam adjusting unit 450 moves the sector orientation of the main beam base station toward the hole center point within the hole region when no main beam force is present in the hole region from the base station. Here, when the sector orientation of the main beam base station is moved toward the center of the hole, the beam adjusting unit 450 moves to a maximum movable angle (Max_Ori_Step), and moves by a preset unit every time it moves.

The hole generation prevention unit 470 moves the orientation of the adjacent base station by the compensation angle (Nei_Beam_Step) of the adjacent base station at the time of beam adjustment by the beam adjustment unit 450.
That is, the hole generation prevention unit 470 moves the orientation of the neighbor base station by the compensation angle (Nei_Beam_Step) of the adjacent base station in the sub-beam direction every time the sector orientation of the sub-beam base station moves, Thereby preventing occurrence of a hole region that may occur.
In addition, the hole generation prevention unit 470 moves the orientation of the adjacent base station by the compensation angle (Nei_Beam_Step) of the adjacent base station every time the sector orientation of the main beam base station moves, Prevent the occurrence of areas.

The simulation execution server 610 performs a simulation on the mobile communication network of the corresponding area according to the instruction of the simulation execution management server 500 to predict the change of the surrounding propagation environment due to the sub beam movement and stores the predicted result S111).

The hole removal operation processing server 400 confirms whether the sub-beam orientation is greater than the maximum movable orientation angle based on the result predicted by the simulation execution server 610. As a result, if the sub-beam orientation is the maximum movable orientation If the angle is larger than the angle, the coverage hole removal procedure is terminated. If the sub-beam orientation is smaller than the maximum movable orientation angle, the operation after step S103 is repeated (S113).

As a result, the hole removal operation processing server 400 moves the sector orientation of the base station corresponding to the sub-beam according to the situation in the hole area through steps S103 to S113, .
