The following describes in detail a deployment method of a radio access network device provided in an embodiment of the present application, with reference to the communication system shown in fig. 1 and the deployment apparatus of the radio access network device shown in fig. 2 (or fig. 3).

Fig. 4 is a flowchart illustrating a deployment method of a radio access network device according to an embodiment of the present application. As shown in fig. 4, the deployment method of the radio access network device includes the following S401-S405.

S401, the deployment device of the wireless access network equipment determines that any adjacent three wireless access network equipment to be deployed are not located on the same side of the track, and the planar shape between any adjacent three wireless access network equipment to be deployed is a regular triangle.

With the development of communication technology, the communication technology is applied to a train positioning method, and the position of a train can be quickly and accurately positioned. In a train positioning method based on a communication technology, a radio access network device is generally deployed near a track on which a train travels or stops. In order to ensure the accuracy of train positioning, the positioning device usually determines the position of the train by triangulation. In this case, the deployment means of the radio access network device needs to deploy at least three radio access network devices on both sides of the track of the train to determine the position of the train.

Specifically, in order to ensure that signals of at least three to-be-deployed radio access network devices can completely cover a track on which a train runs or stops, the deployment apparatus of the radio access network device deploys the at least three to-be-deployed radio access network devices on two sides of the track, that is, in the at least three to-be-deployed radio access network devices, any adjacent three to-be-deployed radio access network devices are not located on the same side of the track, and a planar shape between any adjacent three to-be-deployed radio access network devices is a regular triangle.

Illustratively, as shown in fig. 5a, of the at least three radio access network devices to be deployed, the target radio access network device 51, the first radio access network device 52, the second radio access network device 53, the third radio access network device 54, and the fourth radio access network device 55 are deployed on both sides of the track of the train 56, and a plane graph a1 formed by the target radio access network device 51, the first radio access network device 52, and the second radio access network device 53 is a regular triangle. The planar figure a2 composed of the target radio access network device 51, the first radio access network device 52 and the third radio access network device 54 is a regular triangle. The planar figure a3 composed of the target radio access network device 51, the second radio access network device 53 and the fourth radio access network device 55 is a regular triangle.

S402, the deployment device of the wireless access network equipment presets the shortest distance between the target wireless access network equipment and the track as a first distance, and determines a first relation and a second relation according to the first distance.

The target wireless access network device is any one of at least three wireless access network devices to be deployed. The first relationship is a relationship between a geometric dilution of precision of the target radio access network device and the first distance. The second relationship is between the channel capacity of the target radio access network device and the first distance.

When the deployment device of the wireless access network equipment deploys at least three wireless access network equipment to be deployed, because the first distance is unknown, the deployment device of the wireless access network equipment presets the shortest distance between the target wireless access network equipment and the track as the first distance, and determines the first relation and the second relation according to the first distance so as to ensure the positioning accuracy and the resource utilization rate of the wireless access network equipment.

Specifically, when the deployment apparatus of the radio access network device deploys at least three radio access network devices to be deployed, the positioning accuracy of the at least three radio access network devices to be deployed and the resource utilization rate of the at least three radio access network devices to be deployed need to be ensured. In this case, since the geometric accuracy factor of the radio access network device is an important coefficient for measuring the positioning accuracy, it represents a distance vector amplification factor between the deployment device of the radio access network device and the train caused by the ranging error of the global positioning system. Therefore, the deployment apparatus of the radio access network device may determine, according to the first distance, a relationship between the geometric accuracy factor of the target radio access network device and the first distance, so as to ensure the positioning accuracy of the radio access network device.

Secondly, since the channel capacity of the radio access network device reflects the maximum amount of information that can be transmitted by the channel, the deployment apparatus of the radio access network device can determine the relationship between the channel capacity of the target radio access network device and the first distance, so as to ensure the resource utilization rate of the radio access network device.

Optionally, when determining the first relationship according to the first distance, the deployment apparatus of the radio access network device may first obtain the height of the target radio access network device, and then determine the first relationship according to the height of the target radio access network device and the first distance.

Specifically, when the first relationship is determined, the deployment device of the radio access network device may determine, according to the height of the target radio access network device and the first distance, the volume of the area formed by the deployment device of the radio access network device and the unit vector of the train.

The volume V of an area formed by the deployment device of the radio access network equipment and the unit vector of the train, the height h of the target radio access network equipment and the first distance d satisfy the following formula (1):

since the geometric accuracy factor is inversely proportional to the volume of the area formed by the deployment device of the radio access network device and the unit vector of the train, the volume V and the geometric accuracy factor G of the area formed by the deployment device of the radio access network device and the unit vector of the train satisfy the following formula (2):

where ρ is a first coefficient.

In conjunction with equation (1) and equation (2) above, the deployment means of the radio access network device determines the first relationship. Namely, the height h, the geometric accuracy factor G and the first distance d of the target radio access network device satisfy the following formula (3):

optionally, when the second relationship is determined according to the first distance, the deployment apparatus of the radio access network device first presets that the train is located within the target range, the position of the train is the first position, then determines the transmission power allocated to the target radio access network device according to the power constraint relationship among the three radio access network devices, and then determines the second relationship according to the height of the target radio access network device, the first distance, the first position, and the transmission power.

Wherein, the train is the train on the track. The target range is a range covered by both the first signal and the second signal. The first signal is a signal transmitted by the target wireless access network equipment; the second signal is a signal transmitted by two radio access network devices to be deployed adjacent to the target radio access network device. The three wireless access network devices are a target wireless access network device and two wireless access network devices to be deployed adjacent to the target wireless access network device.

Further optionally, the deploying device of the radio access network device may determine the second relationship according to a path loss model and a water-filling power allocation algorithm.

Specifically, when determining the second relationship according to the height, the first distance, the first position, and the transmission power of the target radio access network device, the deployment apparatus of the radio access network device determines the relationship between the third distance and the first distance according to the height, the first distance, and the first position of the target radio access network device, determines the relationship between the radio channel gain of the target radio access network device and the first distance according to the relationship between the third distance and the first distance, and determines the second relationship according to the relationship between the radio channel gain and the first distance, and the transmission power.

And the third distance is a straight-line distance between the target wireless access network equipment and the train.

Specifically, for convenience of description later, the deployment apparatus of the radio access network device establishes a cartesian right-hand rectangular coordinate system with a center of a regular triangle formed by three to-be-deployed radio access network devices, which are arbitrarily adjacent to each other and are not located on the same side of the track, as an origin. The positive direction of the x axis is parallel to the advancing direction of the train, the direction of the y axis is vertical to the track direction, and the direction of the z axis is parallel to the normal direction of the ground.

The method comprises the steps of presetting the shortest distances between three to-be-deployed wireless access network devices with regular triangle planar shapes and a track as d, presetting the height h of the wireless access network devices, and when the position of a train is X, determining the position of a first to-be-deployed wireless access network device in the three to-be-deployed wireless access network devices with regular triangle planar shapes as:

the position of the second radio access network device to be deployed is: (0, -d, h). The position of the third radio access network device to be deployed is:

in this case, the deployment apparatus of the radio access network device determines the distances between the three radio access network devices to be deployed and the train according to the positions of the three radio access network devices to be deployed, which have the regular triangle planar shape, that is, determines the relationship between the third distance and the first distance according to the height of the target radio access network device, the first distance, and the first position.

Specifically, the distance r1 between the first radio access network device to be deployed and the train is:

the distance r2 between the second radio access network device to be deployed and the train is:

the distance r3 between the third radio access network device to be deployed and the train is:

after determining the relationship between the third distance and the first distance, the deployment apparatus of the radio access network device determines the relationship between the radio channel gain of the target radio access network device and the first distance according to the relationship between the third distance and the first distance.

Specifically, the third distance r and the radio channel gain L satisfy the following formula (4):

L＝αe^-βrformula (4)

Wherein, alpha is a second coefficient, e is a natural base number, and beta is a path loss index.

R1, r2, and r3 are substituted into equation (4) to determine the relationship between the third distance and the first distance for the three radio access network devices to be deployed.

Then, the deployment device of the wireless access network equipment determines the transmitting power distributed to the target wireless access network equipment according to the power constraint relation among the three wireless access network equipment.

Specifically, for three radio access network devices to be deployed with a regular triangle planar shape, in order to ensure that the three radio access network devices to be deployed are composed of three radio access network devices to be deployedThe resource utilization rate of the communication system is the maximum, so the deployment device of the radio access network equipment determines the total transmission power P0 of three radio access network equipment to be deployed [ P1, P2, P3 ] by the lagrangian multiplier algorithm according to the water filling principle]^T。

Wherein, P1 is the transmission power of the first radio access network device to be deployed, P2 is the transmission power of the second radio access network device to be deployed, and P3 is the transmission power of the third radio access network device to be deployed.

The transmission power of the first to-be-deployed radio access network device, the transmission power of the second to-be-deployed radio access network device and the transmission power of the third to-be-deployed radio access network device all satisfy the following formula (9) and formula (10):

wherein, P_iFor indicating the transmission power, L, of the ith radio access network device of the three radio access network devices to be deployed_iThe parameter is used for representing the wireless channel gain of the ith wireless access network device among the three wireless access network devices to be deployed, and mu is a dimensionless parameter.

After determining the relationship between the wireless channel gain of the target wireless access network device and the first distance and the transmission power allocated to the target wireless access network device, the deployment apparatus of the wireless access network device determines the second relationship according to the relationship between the wireless channel gain and the first distance and the transmission power.

Specifically, the wireless channel gain L and the transmission power P_iAnd the channel capacity C satisfies the following formula (7):

wherein σ²Is the power spectral density, L_iUsed for representing the wireless channel gain of the ith wireless access network device in the three wireless access network devices to be deployed.

S403, the deployment device of the wireless access network equipment determines the value of the first distance according to the first relation, the second relation and a preset algorithm.

Specifically, after the first relationship and the second relationship are determined, the deployment apparatus of the radio access network device may construct a multi-objective optimization problem including a geometric precision factor and a channel capacity, and determine a value of the first distance according to a preset algorithm. The multi-objective optimization problem is a convex optimization problem, and the deployment device of the wireless access network equipment can solve the convex optimization problem through a Monte Carlo method or other optimization methods.

Optionally, in order to ensure the accuracy of the positioning accuracy of the target radio access network device and the resource utilization rate of the target radio access network device, the deployment apparatus of the radio access network device determines that the preset conditions are as follows: the geometric form factor is minimal and the channel capacity is maximal. In this case, the deployment apparatus of the radio access network device may determine the value of the first distance according to a monte carlo method, an optimization method, or the like.

Optionally, when the train is at any position, only the three radio access network devices closest to the train are selected for communication and positioning, and when the train is located at an intersection point of a connecting line of the two radio access network devices and the track, the two radio access network devices are selected for communication and positioning with the one radio access network device closest to the train operation front.

Maximum communication distance r of each radio access network device_maxShould cover the track inside three triangles, i.e.

So as to ensure that the train is at any position and at least in the effective coverage area of the signals of the three wireless access network devices.

When the train is located at any position of the track, three adjacent trains are always locatedThe wireless access network equipment enables the train to be positioned inside a regular triangle formed by the three wireless access network equipment, so that the deployment device of the wireless access network equipment determines that the train is positioned

Operate within the range of (1).

Optionally, the geometric accuracy factor G, the channel capacity C, the position X of the train, and the first distance d satisfy the following formula (8):

wherein n is a fixed constant, n is a constant,

for expressing the optimal solution of d in the case of C max and G min, and
