detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a dense high-power wireless networking. In the schematic diagram, a gray point is a base station location, and each gray circle is a signal coverage range of the base station. In the process of dense high-power wireless networking, the base station is no longer in accordance with the cellular networking, and there is no longer a topology of macro cells and micro cells. The reason for such network evolution is to improve the synergy gain of the wireless network and maximize the performance of the wireless communication system. However, in the process of promoting dense high-power wireless networking, direct replacement of equipment will result in waste of investment costs of existing equipment and will not be supported by operators. Even if the operator supports device replacement, the selection and deployment of new site locations is difficult. To this end, the embodiments of the present invention provide a method and a data center for wireless network evolution, which can quickly determine a manner in which a wireless network evolves, thereby reducing the cost of the layout.

As shown in FIG. 2, FIG. 2 illustrates a method for evolving a wireless network according to an embodiment of the present invention, where the method specifically includes steps 101 to 104.

101. The data center determines an area of pre-cooperative communication;

The data center may determine the area of the pre-cooperative communication according to the area. For example, the pre-coordination area may be a city, or a commercial center or a county or a village.

The data center may determine the pre-coordination area according to the distribution of the base stations in the network where the data center is located. For example, the data center can determine the location of the base station in the network where the data center is located, then determine the signal coverage of the base station, and then determine an area that can cover the signal coverage of the base station, and determine the area as pre-cooperative communication. Area.

Among them, the data center can receive the area of pre-cooperative communication input by the operator.

The area of the pre-cooperative communication may be a square or a circle, or may be various shapes, which is not mentioned here.

102. The data center divides the area into squares and determines grid points on the squares;

As shown in FIG. 3, in another embodiment of the present invention, assuming that the area of the pre-cooperative communication is a square, the data center may divide the area of the pre-cooperative communication into multiple squares according to its own computing capability, and Determine the grid points on each square.

In another embodiment of the present invention, the data center may determine the size of the square according to the signal coverage of the base station, and may also determine the size of the square according to the computing power of the data center itself and the signal coverage of the base station. The base station is a base station in a network where the data center is located.

103. The data center determines whether the grid point satisfying the signal coverage requirement reaches a preset ratio;

Wherein, for example, the signal coverage of the base station requires signal coverage of at least two base stations per grid point, and the preset ratio is 95%. Then, the data center needs to calculate whether each grid point is covered by at least two base station signals, and judge whether the grid point satisfying the signal coverage requirement of the base station reaches 95%.

The preset ratio may be determined according to the terrain, the population, and the population distribution in the pre-cooperative communication area. For example, if the population is large and the population is evenly distributed, then the preset ratio can be as high as 95%, etc., for example, if the population is small and the population distribution is uneven, the preset ratio can be set. Lower, such as 60%, etc., is not mentioned here.

104. When the grid point satisfying the signal coverage requirement does not reach the preset ratio, the data center executes a preset processing scheme according to the position of the grid point that does not satisfy the signal coverage requirement, so that the grid point satisfying the signal coverage requirement reaches a preset ratio. .

The data center calculates the number of grid points that meet the signal coverage requirements of the base station. When the number of grid points does not reach the preset ratio, the data center performs a preset processing scheme to minimize the signal coverage requirements of the base station. The grid points are transformed into grid points that satisfy the signal coverage requirements of the base station, thereby increasing the proportion of grid points that satisfy the signal coverage requirements of the base station.

As can be seen from the above, the wireless network evolution method provided by the embodiment of the present invention determines the area of pre-cooperative communication; the data center divides the area into squares, and determines grid points on the square The data center determines whether the grid point satisfying the signal coverage requirement of the base station reaches a preset ratio; when the grid point satisfying the signal coverage requirement of the base station does not reach a preset ratio, the data center is based on the grid that does not satisfy the signal coverage requirement The position of the point, the preset processing scheme is executed; Determining whether the grid point satisfying the signal coverage requirement reaches a preset ratio to determine whether a wireless network evolution is required, and if a wireless network evolution is required, performing a preset processing scheme according to a location of a grid point that does not satisfy the signal coverage requirement, thereby performing a preset processing scheme, thereby It can quickly push the wireless network to evolve and reduce the cost of the layout.

202. The data center determines a signal coverage requirement according to a location of the base station and a signal coverage of the base station.

Wherein, if the location of the base station in the topology network is dense, the signal coverage of the base station is large, and the base station is evenly distributed in the area of the pre-cooperative communication, the signal coverage requirement of the base station is high; otherwise, the signal coverage requirement of the base station is low.

The signal coverage requirement of the base station may be reflected by at least four base station signal coverages per cell point; the low signal coverage requirement of the base station may be reflected by at least two base station signal coverages per cell point.

1042. The data center determines, according to the network topology, a base station that is less than a preset distance from a location of the grid point that does not satisfy the signal coverage requirement;

In another embodiment of the present invention, after determining that the data center does not satisfy the signal coverage requirement, the data center may send an instruction to adjust the tilt angle of the antenna to the base station that is smaller than the preset distance, so that the base station automatically adjusts the antenna downtilt angle. The angle is used to expand the coverage of the base station signal, so that the grid points that do not meet the signal coverage requirements meet the signal coverage requirements.

In another embodiment of the present invention, after the data center determines the grid point that does not meet the signal coverage requirement, the base station may send an instruction to adjust the tilt angle of the antenna to the base station that is less than the preset distance, so that the base station sends the adjusted antenna to the user.

In another embodiment of the present invention, after determining that the data center does not satisfy the signal coverage requirement, the data center may send an indication of replacing the power amplifier component to the base station that is less than the preset distance, so that the base station smaller than the preset distance is to the operator. The operator sends a reminder to replace the power amplifier component, and the operator replaces the power amplifier component or adjusts the power of the power amplifier component according to the reminder, thereby expanding the coverage of the base station signal, so that the grid point that does not meet the signal coverage requirement meets the signal coverage requirement. The power amplifier component may be a radio remote unit, a feeder, or the like.

In another embodiment of the present invention, the base station's preference coverage during the dense networking process The range is basically 500 meters to 1000 meters, and the power consumption is about 1W-5W. If the power amplifier is directly replaced, for example, the range is replaced by 40W, the coverage will increase by 2-3 times, and the number of cooperative base stations will be greatly increased.

When the grid point that meets the signal coverage requirement still does not reach the preset ratio, the data center sends a third message to the administrator by using the operation and maintenance center, where the third message is used to indicate the administrator. The number of antennas of the base station smaller than the preset distance is increased, so that the base station that increases the antenna expands the signal coverage.

In another embodiment of the present invention, after the data center determines the grid point that does not meet the signal coverage requirement, the base station may send an indication of adding the antenna to the base station smaller than the preset distance, so that the base station smaller than the preset distance sends the base station to the operator. The antenna is added to remind the operator to increase the antenna according to the reminder, thereby expanding the coverage of the base station signal, so that the grid point that does not meet the signal coverage requirement meets the signal coverage requirement. The number of antennas that need to be added can be calculated by the data center according to the preset distance, or can be determined by the operator according to actual scenarios and personal experience.
