detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In order to make the advantages of the technical solution of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, the microwave network planning method provided by the embodiment of the present invention includes:

Step 101, perform topology planning on the microwave network.

Specifically, the topology planning is to classify each node in the microwave network to determine the weights of the links between the nodes in the microwave network, and according to the weights of the links between the nodes in the microwave network, According to the weights in the microwave network, the link between each node is planned.

For example, the node classification may be determined according to the geographic location information of each node in the microwave network, and the weight of the location closer to the center is higher, otherwise the weight is lower, but it is not limited thereto. For example, when planning a microwave network for a certain geographical area, the node at the center of the geographical area can be set as a level 1 central node, and the microwave network includes multiple sub-dense areas, and the multiple sub-dense areas pass through the The first-level central node is connected, and the nodes at the edge of the geographical area can be set as leaf nodes. The microwave network can also include second-level nodes, third-level nodes, etc., but it is not limited thereto.

Step 102: Perform capacity planning on the microwave network according to the result of the topology planning, and determine whether the capacity planning is successful.

Wherein, the capacity planning is to configure equipment for each link of each node in the microwave network. If the capacity planning fails, go back to step 101, otherwise go to step 103.

Specifically, the capacity planning is to set the weight of equipment required for each link at each node according to the result of the topology planning and an optimization goal, wherein the optimization goal includes emphasizing performance or controlling costs, Traverse the device database in the microwave network, and configure corresponding devices for the links between the nodes according to the weight of the devices required by each link at the nodes.

Step 103, perform spectrum allocation, and determine whether the spectrum allocation is successful. If the frequency spectrum allocation fails, return to step 101 or step 102, otherwise perform step 104.

Wherein, the frequency spectrum allocation is to prioritize the links between the nodes according to the optimization target and the weights of the links between the nodes, and according to the priority between the nodes Sorting, traversing the spectrum resources of each link, and allocating spectrum resources for each link.

Step 104, output the result of the microwave network planning.

Specifically, the results of the microwave network planning include the link connection relationship between each node, the frequency of each link, and the configuration of the equipment at each node (such as equipment model, equipment size, equipment operating power, etc.), but It's not just limited to this.

The microwave network planning method provided by the embodiment of the present invention performs topology planning on the microwave network, performs capacity planning according to the result of the topology planning, and determines whether the capacity planning is successful. After the capacity planning fails, Returning to performing topology planning on the microwave network, performing spectrum allocation when the capacity planning is successful, and determining whether the spectrum allocation is successful, and returning to performing capacity planning or topology planning on the microwave network after the spectrum allocation fails, Until the frequency spectrum allocation is successful, the result of the microwave network planning is output. In this way, taking into account the impact of topology planning, capacity planning and spectrum planning on microwave network planning, when frequency allocation fails in microwave network planning, the problem of frequency allocation failure can be solved by re-performing topology planning or capacity planning, thereby avoiding the use of Nodes change frequencies, resulting in a waste of spectrum resources.

As shown in FIG. 2, the microwave network planning method provided by another embodiment of the present invention includes:

Step 201. Perform node classification on each node in the microwave network, so as to determine the weight of the link between each node in the microwave network.

Specifically, the node classification may be determined according to the position of each node in the microwave network, and the link weight between nodes whose positions are closer to the center is higher, otherwise the weight is lower, but it is not limited to this. For example, when planning a microwave network for a certain geographical area, the node at the center of the geographical area can be set as a level 1 central node, and the microwave network includes multiple sub-dense areas, and the multiple sub-dense areas pass through the The first-level central node is connected, and the nodes at the edge of the geographical area can be set as leaf nodes. The microwave network can also include second-level nodes, third-level nodes, etc., but it is not limited thereto.

Step 202: Plan the links between the nodes according to the weights of the links between the nodes in the microwave network.

Specifically, the planning of links between each node may be to use a multi-constraint minimum spanning tree algorithm, so as to construct a tree including each node.

Step 203, according to the result of topology planning and the optimization target, set the weight of the equipment required by each link at each node.

Wherein, the optimization goal includes emphasizing performance or controlling cost, but is not limited thereto. Specifically, there are multiple types of equipment required for each link at each node (such as antennas, outdoor unit equipment, indoor unit equipment, etc.), and there may be multiple types of equipment (such as different types of antennas, etc.) , if the optimization goal is to focus on performance, when setting the weight of the equipment required by each link at each node, the equipment with high performance has a higher weight, and the equipment with low performance has a lower weight; if the The optimization goal is to control the cost, and when setting the weight of the equipment required by each link at each node, cheap equipment has a higher weight. But not limited thereto, the optimization objective may also comprehensively consider the performance and cost of equipment, for example, the optimization objective is cost performance, and the weight of equipment with high cost performance is set to be high.

Step 204, traverse the device database in the microwave network, and configure corresponding devices for the links between the nodes according to the weight of the devices required by each link at the nodes.

Specifically, different links may need to be configured with different devices, and the devices required for the links between the various nodes can be recorded in the device database in the microwave network, for example, the device database records the identity of the device (Identity, ID for short), device model, size, and supported link bandwidth, etc., but not limited thereto. According to the weight of the equipment required by each link at each node, find the ID of the equipment with the highest weight of each link at each node in the equipment database, so that each link at each node The link configures the corresponding device.

Step 205: Detect at each node whether the corresponding device can work normally on the link where the corresponding device is located, so as to determine whether the corresponding device meets the requirements of the link where it is located. If the corresponding device cannot work normally on the link where it is located, it means that the requirement of the link where it is located is not met, and the link cannot work normally, and step 206 is performed; otherwise, step 207 is performed.

Specifically, the determination of whether the corresponding device satisfies the requirements of the link where it is located may be by detecting whether the device has problems or even fails to work normally when the link where it is located, for example, the The transmission power of the link must reach a certain threshold, but the transmission power of the device selected through the optimization target and device weight cannot reach the threshold, which will cause the device selected through the optimization target and device weight to be unable to If the device works normally on the link, it is determined that the device does not meet the requirements of the link where it is located.

Step 206, increase the weight of the link that cannot work normally. Return to step 202.

Specifically, because the corresponding device cannot work normally on the link where it is located, causing the link to fail to work normally, the weight of the link that cannot work normally can be increased, so that the link between each node The planning changes, so that the subsequent steps will reconfigure the equipment for the links between the nodes, and the weight of the links increases, so that the probability of selecting the equipment for this application again in the subsequent steps is reduced.

Step 207: Prioritize the links between the nodes according to the optimization target and the weights of the links between the nodes.

Specifically, when transmitting signals in the later stage, since different optimization objectives may need to be transmitted through different links between each node, it is necessary to optimize the weights of the links between each node according to the optimization objectives and the weights The links between them are prioritized.

Step 208: Traverse the spectrum resources of each link according to the priority ranking of the links between the nodes, and allocate spectrum resources for each link.

Specifically, there is a better preferred frequency in the spectrum resource, and the preferred frequency may be allocated to a link with a higher link priority, but it is not limited thereto.

Step 209: Detect frequency interference between spectrum resources of each link, and determine whether the frequency interference meets the requirements of the key performance indicator KPI. If the frequency interference does not meet the requirements of the KPI, resulting in that the link after the frequency allocation cannot work normally, go to step 210 or step 206, otherwise go to step 211.

Specifically, the KPI includes: frequency availability and error performance indicators, etc., but is not limited thereto.

Step 210, excluding devices currently used by nodes related to the link and devices that have higher requirements for receiving performance indicators than the devices. Return to step 203.

Specifically, after the frequency interference cannot meet the requirements of the KPI, the device currently used by the node related to the link can be reconfigured to finally meet the requirements of the KPI. In order to make the microwave network After successful reduction of the maximum number of frequencies, devices with lower requirements for receiving performance indicators (such as transmitting power or receiving power) than the original devices can be used when reconfiguring the devices of the nodes related to the link.

Step 211, output the result of the microwave network planning.

Specifically, if the frequency interference satisfies the requirements of the KPI, output the result of the microwave network planning, the result of the microwave network planning includes the link connection relationship between each node, the frequency of each link, and each The configuration of the device at the node (such as device model, device size, device working power, etc.), but not limited thereto.

When the capacity planning is successful, perform spectrum allocation and determine whether the spectrum allocation is successful. After the spectrum allocation fails, return to the capacity planning or topology planning of the microwave network. planning until the frequency spectrum allocation is successful, and output the result of the microwave network planning. In this way, taking into account the impact of topology planning, capacity planning and spectrum planning on microwave network planning, when frequency allocation fails in microwave network planning, the problem of frequency allocation failure can be solved by re-performing topology planning or capacity planning, thereby avoiding the use of Nodes change frequencies, resulting in a waste of spectrum resources.
