[0003] However, in existing wireless mesh networks, wireless network resource allocation is usually based on the service data request volume and physical resource block (PRB) utilization rate.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0050] In order to solve the technical problem of unreasonable wireless network resource allocation in wireless mesh networks in the prior art, the present application provides a wireless network resource allocation method, which can allocate sufficient wireless network resources to nodes with higher service data priority, and can also effectively avoid the occurrence of unreasonable wireless network resource allocation.

[0051] See also Figure 1 , Figure 1 A flowchart of a wireless network resource allocation method provided in an embodiment of the present application. Figure 1 As shown, the wireless network resource allocation method may include the following steps:

[0052] Step 101: Obtain node information corresponding to each node in a target wireless network, wherein the node information includes service data information and channel quality information between each node and all its corresponding neighboring nodes.

[0053] It should be noted that the wireless network resource allocation method provided in the embodiment of the present application is applied to a master node in a target wireless network, and the master node can be used to allocate wireless network resources to each node in the target wireless network. The master node can be any node in the target wireless network.

[0054] Specifically, the target wireless network may be a MESH network, etc., which may include multiple nodes, such as at least one master node and at least one slave node. When there are multiple master nodes, when the master node fails, a backup master node may be started to take over the work of the original master node. Each node may broadcast its own node information in real time or at a fixed time, so that the master node can obtain the node information corresponding to each node. The node information at this time may include service data information and channel quality information between each node and all its corresponding neighboring nodes. For example, in Figure 2 In the target wireless network of the topology structure shown, assuming that the main node is node B, node B can obtain the node information of node A, node B, node C and node D, wherein the node information of node A includes the service data information and channel quality information between node A and node B, the service data information and channel quality information between node A and node C, and the service data information and channel quality information between node A and node D; the node information of node B includes the service data information and channel quality information between node B and node A; the node information of node C includes the service data information and channel quality information between node C and node A; the node information of node D includes the service data information and channel quality information between node D and node A.

[0055] Step 102: Determine the service data priority and required time slot resource quantity corresponding to each node according to the service data information and channel quality information.

[0056] In this step, after obtaining the node information corresponding to each node, the master node can determine the service data priority and the required number of time slot resources corresponding to each node according to the node information corresponding to each node. Specifically, the type of service data corresponding to each node can be determined according to the service data information corresponding to each node, and then the service data priority corresponding to each node can be determined according to the type of service data corresponding to each node and the priority corresponding to the pre-set type of service data; the bandwidth requirement required by each node can also be determined according to the service data information corresponding to each node, and then the number of time slot resources required by each node can be determined according to the bandwidth requirement and channel quality information required by each node. Of course, other methods can also be used to determine the service data priority and the required number of time slot resources corresponding to each node, which is not specifically limited in the embodiments of the present application.

[0057] Step 103: Allocate wireless network resources to each node in the target wireless network according to the service data priority and required number of time slot resources corresponding to each node.

[0058] In this step, after determining the service data priority and the required number of time slot resources corresponding to each node, the master node can allocate a reasonable number of time slot resources to each node according to the service data priority and the required number of time slot resources corresponding to each node, so as to achieve the purpose of allocating wireless network resources to each node. For example, the number of time slot resources required by each node can be allocated in sequence from high to low or from low to high in the order of service data priority. When there are multiple nodes with the same service data priority, different allocations can be made according to the number of idle wireless network resources. For example, when the idle wireless network resources are insufficient, the allocation requirements of nodes with a smaller number of required time slot resources can be met first. When the idle wireless network resources are sufficient, multiple nodes with the same service data priority can be allocated according to the demand ratio.

[0059] In this embodiment, the wireless network resources of each node can be allocated by comprehensively considering the service data priority and the required number of time slot resources of each node in the target wireless network. In this way, it can not only effectively ensure that nodes with higher service data priority can be allocated sufficient wireless network resources, but also effectively avoid the occurrence of unreasonable wireless network resource allocation.

[0060] Furthermore, the service data information includes the type of service data and bandwidth requirements;

[0061] The above step 102, determining the service data priority and the required number of time slot resources corresponding to each node according to the service data information and the channel quality information, specifically includes:

[0062] Determine the service data priority corresponding to each node according to the type of service data and the preset corresponding relationship, wherein the preset corresponding relationship is used to characterize the corresponding relationship between the type of service data and the service data priority;

[0063] The number of time slot resources required by each node is determined based on bandwidth requirements and channel quality information.

[0064] Specifically, the types of the above-mentioned business data include but are not limited to MESH network maintenance data, voice business data, video business data, etc. The above-mentioned bandwidth requirement refers to the bandwidth required for the node to transmit business data with its neighboring node, and the bandwidth requirement is proportional to the amount of business data transmitted between nodes. The above-mentioned preset correspondence is used to characterize the correspondence between the type of business data and the priority of the business data. As an optional implementation, the preset correspondence can be shown in the following table:

[0065]

[0066] In one embodiment, after obtaining the node information corresponding to each node, the master node can determine the service data priority and the required number of time slot resources corresponding to each node according to the node information corresponding to each node. Specifically, the type of service data corresponding to each node can be determined according to the service data information corresponding to each node, and then the service data priority corresponding to each node can be determined according to the type of service data corresponding to each node and the preset corresponding relationship; and the bandwidth requirement required by each node can be determined according to the service data information corresponding to each node, and then the number of time slot resources required by each node can be determined according to the bandwidth requirement and channel quality information required by each node. In this way, it is convenient for the master node to reasonably allocate the wireless network resources of each node in the target wireless network according to the service data priority and the required number of time slot resources corresponding to each node.

[0067] Furthermore, the above steps, based on the bandwidth requirements and the channel quality information, determine the number of time slot resources required by each node, specifically including:

[0068] Calculate the ratio of the bandwidth requirement to the channel quality information between the target node and each of its corresponding neighboring nodes respectively, wherein the target node is any node in the target wireless network, and the channel quality information is the size of the transmission block required for the target node to transmit service data with each of its neighboring nodes;

[0069] The sum of the ratios is calculated and determined as the number of time slot resources required by the target node.

[0070] Specifically, the target node may be any node in the target wireless network. The channel quality information may be the size of a transmission block required for the target node to transmit service data with each neighboring node, and the size of the transmission block here may be reflected by the size of a channel quality indication (CQI) and a signal to interference plus noise ratio (SINR).

[0071] In one embodiment, when determining the number of time slot resources required by each node, the ratio of the bandwidth requirement to the channel quality information between the target node and each of its corresponding neighboring nodes may be calculated respectively, and then the sum of the ratios may be calculated, and the sum of the ratios may be determined as the number of time slot resources required by the target node. Specifically, the following formula may be used to calculate the ratio of the bandwidth requirement to the channel quality information between the target node and one of its neighboring nodes: ratio = bandwidth requirement between the target node and one of its neighboring nodes / size of the transmission block of the neighboring node.

[0072] It should be noted that the transmission block size of the neighboring node here refers to the modulation and coding scheme (MCS) TBsize. In a MESH network, the target node may have multiple neighboring nodes at the same time, and multiple neighboring nodes must share the time slot resources of the target node. Therefore, it is necessary to comprehensively consider the sum of the ratios of the target node to all neighboring nodes as the number of time slot resources required by the target node.

[0073] Through the above method, the number of time slot resources required by any node in the target wireless network can be accurately calculated, which facilitates the subsequent reasonable allocation of wireless network resources to each node.

[0074] Furthermore, the above step 103, allocating wireless network resources of each node in the target wireless network according to the service data priority and the required number of time slot resources corresponding to each node, includes:

[0075] Calculate the total number of time slot resources currently available in the target wireless network;

[0076] Determine whether the service data priority corresponding to each node includes multiple priorities;

[0077] When it is determined that the service data priority corresponding to each node includes multiple priorities, the total number of time slot resources is allocated to each node in sequence according to the service data priority corresponding to each node from high to low.

[0078] In one embodiment, when allocating wireless network resources to each node in the target wireless network, the total number of time slot resources currently available in the target wireless network can be calculated first, and then it is determined whether the service data priority corresponding to each node includes multiple priorities. If it is determined that the service data priority corresponding to each node includes multiple priorities, the total number of time slot resources is allocated to each node in order from high to low according to the service data priority corresponding to each node. In this way, the wireless network resources required by the node with high service data priority can be allocated first, so as to ensure that important service data can be transmitted stably.

[0079] Furthermore, after the above step of determining whether the service data priority corresponding to each node includes multiple priorities, the method further includes:

[0080] When it is determined that the business data priority corresponding to each node includes only one priority, the total number of time slot resources is allocated to each node in sequence from small to large according to the number of time slot resources required by each node, or the total number of time slot resources is allocated to each node according to the ratio of the number of time slot resources required by each node to the total number of time slot resources.

[0081] In one embodiment, if it is determined that the service data priority corresponding to each node includes only one priority, a comparison can be made based on the total number of time slot resources currently available in the target wireless network and the total number of time slot resources currently required by each node to determine whether the currently available time slot resources are sufficient. If the currently available time slot resources are insufficient, the total number of time slot resources can be allocated to each node in order from small to large according to the number of time slot resources required by each node, so as to give priority to meeting the allocation needs of nodes occupying fewer time slot resources. If the currently available time slot resources are sufficient, the total number of time slot resources can be allocated to each node according to the ratio of the number of time slot resources required by each node to the total number of time slot resources, so as to achieve reasonable allocation of wireless network resources for each node.

[0082] Furthermore, before allocating the wireless network resources of each node in the target wireless network according to the service data priority and the required number of time slot resources corresponding to each node in the above step 103, the method further includes:

[0083] Determining whether the target wireless network satisfies a preset resource allocation trigger condition, wherein the resource allocation trigger condition refers to a trigger condition for reallocating wireless network resources of each node in the target wireless network;

[0084] When it is determined that the target wireless network meets the resource allocation triggering condition, a step of allocating wireless network resources to each node in the target wireless network according to the service data priority and the required number of time slot resources corresponding to each node is performed.

[0085] In one embodiment, before the master node allocates the wireless network resources of each node in the target wireless network, it is also necessary to determine whether the target wireless network meets the preset resource allocation trigger condition. If the target wireless network meets the preset resource allocation trigger condition, the wireless network resources of each node in the target wireless network are reallocated; if the target wireless network does not meet the preset resource allocation trigger condition, the last allocation method is maintained unchanged. In this way, the service data in the target wireless network can be better monitored, and the wireless network resources of each node can be allocated in time when the service data changes greatly.

[0086] Furthermore, the resource allocation triggering condition includes at least one of the following:

[0087] There is at least one node corresponding to the business data type of a newly added type;

[0088] There is a change in the number of time slot resources required by at least one node exceeding a preset number;

[0089] There is at least one node whose required number of time slot resources increases or decreases continuously within a preset number of time periods.

[0090] In one embodiment, the resource allocation trigger condition may be that the type of service data corresponding to at least one node is a newly added type, that is, new service data appears in the target wireless network, and wireless network resources need to be allocated to transmit the new service data, so the wireless network resources of each node may be reallocated. The resource allocation trigger condition may also be that the change in the number of time slot resources required by at least one node exceeds a preset number, that is, the service data volume of one or more nodes in the target wireless network changes greatly, and the wireless network resources of each node may be reallocated. The resource allocation trigger condition may also be that the number of time slot resources required by at least one node increases or decreases continuously within a preset number of time periods, that is, the number of time slot resources required by one or more nodes in the target wireless network increases or decreases continuously within multiple consecutive time periods, for example, the number of time slot resources required increases continuously within 5 time periods or the number of time slot resources required decreases continuously within 20 time periods, etc.

[0091] It should be noted that the above preset number can be set according to actual conditions, and the embodiment of the present application does not make specific restrictions. The above resource allocation triggering conditions can also be set according to actual needs, such as using a combination of one or more of the above conditions, and the embodiment of the present application does not make specific restrictions.

[0092] In this embodiment, the resource allocation triggering condition can be flexibly set to implement wireless network resource allocation under different service demand scenarios.

[0093] In one embodiment, the wireless network resource allocation process provided in the embodiment of the present application may include the following steps: Figure 3 As shown:

[0094] Step 301: Each node broadcasts its own node information, wherein the node information includes service data information and channel quality information between each node and all its corresponding neighboring nodes.

[0095] Step 302: The master node calculates the service data priority and the required number of time slot resources corresponding to each node according to the node message corresponding to each node.

[0096] Step 303: The master node adds the service data of each node to the priority queue according to the service data priority.

[0097] Step 304: The master node determines whether there is any new traffic in the target wireless network.

[0098] If there is new traffic in the target wireless network, step 305 is executed; if there is no new traffic in the target wireless network, step 306 is executed.

[0099] Step 305: The master node triggers resource allocation.

[0100] Step 306: The master node determines whether the traffic has not changed during the blocking period.

[0101] If the flow rate does not change during the blocking period, the process ends; if the flow rate changes during the blocking period, step 307 is executed.

[0102] Step 307: The master node determines that the number of time slot resources required within N time periods increases continuously or the number of time slot resources required within M time periods decreases continuously, where N and M are any integers greater than 1.

[0103] If the number of time slot resources required within N time periods increases continuously or the number of time slot resources required within M time periods decreases continuously, execute step 305; if the number of time slot resources required within N time periods does not increase continuously or the number of time slot resources required within M time periods does not decrease continuously, end the process.

[0104] It should be noted that after the above step 305, the master node can also use Figure 4 The allocation method shown is used to allocate wireless network resources, that is, for priority A0 and priority A1 allocation demand queues, the maximum allocation demand of the high priority is fully met first, that is, the allocation is as much as needed; for priority B0 and priority B1 allocation demand queues, resources are allocated in the following order: allocation demand that can be met in B0, allocation demand that can be met in B1, allocation demand that cannot be met in B0, and allocation demand that cannot be met in B1. In other words, when the service data priorities are different, the service with high service data priority is given priority to obtain sufficient resources; when the service data priorities are the same, the allocation demand that occupies less time slot resources is given priority; idle resources are allocated according to the demand ratio within the same priority.

[0105] Through the above method, the service data priority and the required number of time slot resources corresponding to each node in the target wireless network can be comprehensively considered to allocate wireless network resources to each node. In this way, it can not only effectively ensure that nodes with higher service data priority can be allocated sufficient wireless network resources, but also effectively avoid the occurrence of unreasonable wireless network resource allocation.
