Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the exemplary embodiments below do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flow chart illustrating a method of networked device determination in accordance with an exemplary embodiment; the method of the embodiment can be applied to network node equipment in a wireless MESH network.

As shown in fig. 1, the method comprises the following steps S101-S103:

in step S101, in response to receiving the networking request information sent by the mobile terminal, at least one candidate networking device is determined based on the device information of the first network node device scanned by the mobile terminal and the device capability information of the second network node device in the wireless MESH network acquired in advance.

In this embodiment, the mobile terminal may send a networking request to the currently associated network node device to request that a wireless link be formed with the gateway node through the relay function of the network node device, thereby implementing wireless access. However, considering that the network node currently associated with the mobile terminal device is not necessarily the most suitable device for serving as the relay of the mobile terminal, the network node device may obtain the device information of the first network node device scanned by the mobile terminal in response to receiving the networking request information sent by the mobile terminal, and further determine at least one candidate networking device from the second network node devices based on the device information and the pre-obtained device capability information of the second network node devices in the wireless MESH network. Wherein the second network node device comprises a current network node device.

For example, the device information of the first network node device may include first device identification information and signal reception strength of the first network node device.

It is worth noting that the wireless client would measure the received signal strength of each Beacon (radio Beacon) and carry the received signal strength in the Beacon Report, i.e., the received signal strength RCPI in the Beacon Report. The above-mentioned signal reception strength may be a reception signal strength RCPI carried in the Beacon Report, but is not limited thereto.

The RCPI is called a Received Channel Power Indicator in the whole meaning: the current channel signal strength received by the client from the wireless access point.

The device capability information of the second network node device may include second device identification information of the second network node device and a preset wireless connection capability index, such as a supported frequency band, a wireless hop count, a maximum wireless transmission rate, a signal reception strength, and the like.

The method for acquiring the device information of the first network node device may refer to the embodiment shown in fig. 2 or fig. 3, which is not described in detail herein.

The wireless MESH network in this embodiment may be composed of MESH routers (i.e., network node devices in this embodiment; and the network node devices may also include control devices and non-control devices, i.e., common node devices) and MESH clients (i.e., mobile terminals roaming in the wireless MESH network). The mesh routers form a backbone network, are connected with a wired internet network line and are responsible for providing multi-hop wireless internet connection for mesh clients. A wireless Mesh network (wireless Mesh network), also called a "multi-hop" network, is a new wireless network technology completely different from a traditional wireless network.

In step S102, a networking performance evaluation index of the candidate networking device is determined based on the device capability information of the candidate networking device.

In this embodiment, after determining at least one candidate networking device based on the device information of the first network node device scanned by the mobile terminal and the pre-acquired device capability information of the second network node device in the wireless MESH network, the networking performance evaluation index of the candidate networking device may be determined based on the device capability information of the candidate networking device.

It should be noted that, because the candidate networking device is selected from the second network node devices in the wireless MESH network, the device capability information of the second network node device has been acquired before, which means that the device capability information of the candidate networking device has also been acquired.

In an embodiment, the determination manner of the networking performance evaluation index may be referred to the following embodiment shown in fig. 5, and will not be described in detail herein.

In step S103, a target networking device is determined from the at least one candidate networking device based on the networking performance evaluation index.

In this embodiment, after determining the networking performance evaluation index of the candidate networking device based on the device capability information of the candidate networking device, the target networking device may be determined from the at least one candidate networking device based on the networking performance evaluation index. The target networking equipment is used for recommending the mobile terminal to carry out association.

For example, the target networking device may be determined based on the candidate networking device with the largest value of the networking performance evaluation index. For example, the candidate networking device with the largest value of the networking performance evaluation index may be determined as the target networking device recommended to the mobile terminal.

In an embodiment, after determining a target networking device for recommending the mobile terminal to associate, a preset message may be sent to the mobile terminal to suggest that the mobile terminal associates with the target networking device.

It should be noted that the type of the preset message may be set based on actual needs, for example, in a case that it is determined that the mobile terminal has a BSS transmission Management capability, a bs transmission Management Request message may be sent to the mobile terminal to suggest that the mobile terminal is associated with the target networking device.

As can be seen from the above description, in the method of this embodiment, in response to receiving networking request information sent by a mobile terminal, at least one candidate networking device is determined based on device information of a first network node device scanned by the mobile terminal and device capability information of a second network node device in the wireless MESH network, which is acquired in advance, and a networking performance evaluation index of the candidate networking device is determined based on the device capability information of the candidate networking device, and then a target networking device is determined from the at least one candidate networking device based on the networking performance evaluation index.

Fig. 2 is a flow chart illustrating how to obtain device information of a first network node device scanned by the mobile terminal, according to an example embodiment; the present embodiment takes how to obtain the device information of the first network node device scanned by the mobile terminal as an example on the basis of the above embodiments. As shown in fig. 2, the method for determining a networked device of this embodiment further includes obtaining device information of the first network node device scanned by the mobile terminal based on the following steps S201 to S203:

in step S201, the uplink signal strength of the mobile terminal is detected.

In this embodiment, the network node device may detect the uplink signal strength of the mobile terminal according to a preset period.

It should be noted that the network node device is a network node device currently associated with the mobile terminal. For example, when the network node device receives the networking request information sent by the mobile terminal, the uplink signal strength of the mobile terminal may be detected based on a set signal strength detection manner. The set signal strength detection mode may be set based on actual needs, which is not limited in this embodiment.

In step S202, in response to that the uplink signal strength satisfies a set signal strength condition, a scanning device detection request is sent to the mobile terminal.

In this embodiment, after detecting the uplink signal strength of the mobile terminal, it may be determined whether the uplink signal strength satisfies the set signal strength condition, and then, when the uplink signal strength satisfies the set signal strength condition, a scanning device detection request may be sent to the mobile terminal.

In an embodiment, the set signal strength condition may be set based on an actual service requirement, for example, the uplink signal strength of the mobile terminal is set to be greater than or equal to a set signal strength threshold, which is not limited in this embodiment.

In step S203, receiving the device information of the first network node device returned by the mobile terminal based on the scanning device detection request.

In this embodiment, after sending a scanning device detection request to the mobile terminal in response to that the uplink signal strength meets the set signal strength condition, the device information of the first network node device returned by the mobile terminal based on the scanning device detection request may be received.

As can be seen from the above description, in this embodiment, by detecting the uplink signal strength of the mobile terminal, and in response to that the uplink signal strength meets the set signal strength condition, sending a scanning device detection request to the mobile terminal, and then receiving the device information of the first network node device returned by the mobile terminal based on the scanning device detection request, the device information of the first network node device can be accurately obtained, and an accurate basis can be provided for determining at least one candidate networking device based on the device information of the first network node device in the following process.

Fig. 3 is a flow chart illustrating how to obtain device information of a first network node device scanned by the mobile terminal according to yet another exemplary embodiment; based on the foregoing embodiments, this embodiment exemplifies how to acquire the device information of the first network node device scanned by the mobile terminal. As shown in fig. 3, the method for determining a networked device of this embodiment further includes obtaining device information of the first network node device scanned by the mobile terminal based on the following steps S301 to S304:

in step S301, the networking request information is analyzed to obtain the wireless connection capability information of the mobile terminal.

In this embodiment, after receiving the networking request information sent by the mobile terminal, the network node device may analyze the networking request information to obtain the wireless connection capability information of the mobile terminal.

The wireless connection capability information of the mobile terminal may be used to represent whether the mobile terminal supports a preset wireless connection capability, such as whether the mobile terminal supports a Radio Measurement (Radio Measurement) capability, whether the mobile terminal supports a BSS transmission Management capability, a wifi capability, a supported spatial stream, a supported wifi protocol, and the like.

For example, the terminal device may identify, in the wifi management message, a supported wireless spatial stream and a supported protocol according to actual conditions and capabilities of the terminal device. On this basis, if it is determined that the terminal device can support the radio measurement and bs transmission Management capabilities, it may identify whether the terminal device itself supports the corresponding capabilities in the corresponding field of the packet according to the requirements specified in the 802.11 protocol. Ap (Access Point, wireless Access Point) or network node device may extract a wireless capability set corresponding to the terminal device according to the protocol specification when the terminal device is associated.

In step S302, in response to the wireless connection capability information satisfying a set capability condition, detecting an uplink signal strength of the mobile terminal.

In this embodiment, after the wireless connection capability information of the mobile terminal is obtained, it may be determined whether the wireless connection capability information of the mobile terminal meets a set capability condition, and then, when it is determined that the wireless connection capability information meets the set capability condition, the uplink signal strength of the mobile terminal is detected.

In an embodiment, the wireless connection capability information satisfies the set capability condition, which may include: the ability to support Radio Measurement (Radio Measurement).

In step S303, in response to that the uplink signal strength satisfies a set signal strength condition, a scanning device detection request is sent to the mobile terminal.

For example, when it is determined that the uplink signal strength satisfies a set signal strength condition and it is determined that the mobile terminal supports a Radio Measurement (Radio Measurement) capability, the sending the scan device detection request to the mobile terminal may include: and initiating a Radio Measurement Beacon Request (Radio Measurement Beacon Request) to the mobile terminal to determine the device information of the first network node device currently scanned by the mobile terminal.

In step S304, the device information of the first network node device returned by the mobile terminal based on the scanning device detection request is received.

In this embodiment, after a Radio Measurement Beacon Request (Radio Measurement Beacon Request) is initiated to the mobile terminal, a Beacon Report (Beacon Report) returned by the mobile terminal based on the Radio Measurement Beacon Request may be received, where the Beacon Report carries device information of a first network node device currently scanned by the mobile terminal.

For the explanation and explanation of steps S302 to S304, reference may also be made to steps S201 to S203 in the embodiment shown in fig. 2, which is not described herein again.

As can be seen from the above description, in this embodiment, the networking request information is analyzed to obtain the wireless connection capability information of the mobile terminal, and in response to that the wireless connection capability information satisfies a set capability condition, the uplink signal strength of the mobile terminal is detected, and then in response to that the uplink signal strength satisfies the set signal strength condition, a scanning device detection request is sent to the mobile terminal, and the device information of the first network node device, which is returned by the mobile terminal based on the scanning device detection request, is received, so that it can be ensured that the uplink signal strength of the mobile terminal can be successfully detected, and then a scanning device detection request can be sent to the mobile terminal based on the uplink signal strength, so that the device information of the first network node device can be accurately obtained, and then the subsequent determination of at least one candidate networking device based on the device information of the first network node device can be realized.

FIG. 4 is a flowchart illustrating how at least one alternative networking device is determined in accordance with an exemplary embodiment; the present embodiment exemplifies how to determine at least one alternative networking device on the basis of the above-described embodiments.

In this embodiment, the device information of the first network node device may include first device identification information and signal reception strength of the first network node device, and the device capability information of the second network node device may include second device identification information of the second network node device.

On this basis, as shown in fig. 4, the determining at least one candidate networking device based on the device information of the first network node device scanned by the mobile terminal and the pre-acquired device capability information of the second network node device in the wireless MESH network in step S101 may include the following steps S401 to S402:

in step S401, a third network node device in the wireless MESH network is determined from the first network node devices scanned by the mobile terminal based on the first device identification information and the second device identification information.

In this embodiment, after acquiring the first device identification information and the signal reception intensity of the first network node device and the second device identification information of the second network node device, the first device identification information may be matched with the second device identification information to determine a third network node device in the wireless MESH network in the first network node device scanned by the mobile terminal, that is, the third network node device belongs to both the first network node device currently scanned by the mobile terminal and the second network node device in the wireless MESH network.

In step S402, at least one candidate networking device is determined based on a device of the third network node device whose signal reception strength satisfies a set signal strength condition.

In this embodiment, after determining, based on the first device identification information and the second device identification information, a third network node device in the wireless MESH network in the first network node devices scanned by the mobile terminal, the at least one candidate networking device may be determined based on a device whose signal reception strength satisfies a set signal strength condition in the third network node device.

For example, after determining the third network node device, it may be determined whether the signal reception strength of the third network node device satisfies the set signal strength condition, and then the third network node device satisfying the set signal strength condition may be determined as the candidate networking device.

In an embodiment, the signal reception strength satisfying the set signal strength condition may include at least one of the following:

As can be seen from the above description, in this embodiment, the third network node device in the wireless MESH network in the first network node device scanned by the mobile terminal is determined based on the first device identification information and the second device identification information, and the at least one alternative networking device is determined based on the device in the third network node device whose signal reception strength meets the set signal strength condition, so that the determination of the at least one alternative networking device based on the device information of the first network node device scanned by the mobile terminal and the device capability information of the second network node device in the wireless MESH network can be realized, and an accurate basis can be laid for determining a target networking device for recommending the mobile terminal to associate based on the alternative networking device subsequently.

FIG. 5 is a flowchart illustrating how networking performance evaluation indicators for the alternative networking devices are determined based on device capability information of the alternative networking devices, according to an example embodiment; the present embodiment exemplifies how to determine the networking performance evaluation index of the candidate networking device based on the device capability information of the candidate networking device on the basis of the above embodiments.

In this embodiment, the device capability information of the candidate networking device may include a wireless connection capability index preset by the candidate networking device. In one embodiment, the wireless connectivity capability indicator includes at least two of:

On this basis, as shown in fig. 5, the determining the networking performance evaluation index of the candidate networking device based on the device capability information of the candidate networking device in the above step S102 may include the following steps S501 to S502:

in step S501, an index weight of each of the wireless connection capability indexes is determined based on a preset priority of each of the wireless connection capability indexes.

In this embodiment, after determining the candidate networking device, the indicator weight of each wireless connection capability indicator may be determined based on the preset priority of each wireless connection capability indicator of the candidate networking device.

For example, if the wireless connection capability indicators include supported frequency bands, wireless hops, maximum wireless transmission rate, and signal reception strength, the priority of these indicators may be set based on actual needs, for example, the indicators are arranged in order from high to low according to the priority: supported frequency band > radio hop count > maximum radio transmission rate > signal received strength (RCPI).

On this basis, index weights may be determined for each index based on the priority levels of the above-described indexes, for example, the index weights of the supported frequency band, the number of radio hops, the maximum radio transmission rate, and the signal reception intensity are set to 0.4, 0.3, 0.2, and 0.1, respectively. It should be noted that the numerical value of the index weight is only used for exemplary illustration, and may be set to other numerical values according to needs in practical applications, which is not limited in this embodiment.

In step S502, a networking performance evaluation index of the candidate networking device is determined based on the index weight of each of the wireless connection capability indexes.

In this embodiment, after the index weight of each wireless connectivity index is determined based on the preset priority of each wireless connectivity index, the networking performance evaluation index of the candidate networking device may be determined based on the index weight of each wireless connectivity index.

In an embodiment, the networking performance evaluation index of the candidate networking device may be determined according to the following rules:

(1) The smaller the number of clients associated with the frequency band and the smaller the interference of the frequency band, the higher the value of the networking performance evaluation index is;

(2) The smaller the wireless hop count is, the higher the value of the networking performance evaluation index is;

(3) The larger the maximum wireless transmission rate is, the higher the value of the networking performance evaluation index is;

the maximum wireless transmission rate can be calculated based on the spatial stream of the current wireless client, the maximum spatial stream supporting the wifi protocol and the candidate device.

(4) The larger the signal reception strength RCPI, the higher the value of the networking performance evaluation index.

As can be seen from the above description, in this embodiment, by determining the index weight of each wireless connection capability index based on the preset priority of each wireless connection capability index, and determining the networking performance evaluation index of the candidate networking device based on the index weight of each wireless connection capability index, it is possible to implement setting the priority of each wireless connection capability index based on actual needs, and further determine the networking performance evaluation index of each candidate networking device based on the set priority, and thus it is possible to determine a target networking device from at least one candidate networking device based on the networking performance evaluation index subsequently, and it is possible to ensure the networking performance of the target networking device determined for the mobile terminal, and improve the rationality of determining the networking device, and further improve the networking quality of the mobile terminal.

Fig. 6 is a flowchart illustrating how to obtain device capability information for a second network node device in the wireless MESH network in accordance with an example embodiment; based on the foregoing embodiments, this embodiment exemplifies how to acquire the device capability information of the second network node device in the wireless MESH network. As shown in fig. 6, the networking device determining method of this embodiment may further include obtaining the device capability information of the second network node device in the wireless MESH network based on the following steps S601-S602:

in step S601, in response to receiving an instruction for collecting device capability information sent by a control device in the wireless MESH network, sending device capability information of the current network node device to the control device.

In this embodiment, a network node device in a wireless MESH network may report device capability information of a current network node device to a control device (controller) in the wireless MESH network in response to an instruction sent by the controller.

The device capability information may be set based on actual needs, for example, one or more of the following:

(1) Maximum spatial streams supported by each frequency band of the current network node equipment;

(2) The working protocol supported by the current network node equipment;

(3) The wireless hop count of the current network node device;

wherein, the wireless hop count may be defined as: wireless device distance from the network egress. For example, if a certain network node device (e.g., a network node device as a control device) directly accesses the network (i.e., is directly associated with the gateway node), it can be considered that its wireless hop count is 0 hops; if another network node device needs to access the network through N network node devices (which may include a control device), the wireless hop count of the other network node device may be considered to be N hops, where N is a positive integer greater than or equal to 1.

(4) BSSID of each BSS for each frequency band.

In step S602, the device capability information of the second network node device in the wireless MESH network sent by the control device is received.

In this embodiment, after sending, by a network node device, device capability information of a current network node device to a control device in response to receiving a command for collecting device capability information sent by the control device in the wireless MESH network, the device capability information of a second network node device in the wireless MESH network sent by the control device may be received.

The device capability information of the second network node device may be obtained by the control device by summarizing the device capability information of each network node device in the wireless MESH network.

For example, the network node device directly accessing the network may serve as a control device in the current wireless MESH network to collect and summarize device capability information of each network node device in the current wireless MESH network, so as to obtain a device capability information set of all network node devices in the current wireless MESH network, and further, the capability information set may be synchronously shared to each network node device.

It can be understood that, when the device capability information of any network node device in the network changes, the device capability information may be reported to the control device for resynchronization, so that the validity of the device capability information set grasped by each network node device may be ensured.

As can be seen from the above description, in this embodiment, in response to receiving a command for collecting device capability information sent by a control device in the wireless MESH network, the device capability information of the current network node device is sent to the control device, and the device capability information of the second network node device in the wireless MESH network sent by the control device is received, so that accurate acquisition of the device capability information of the second network node device in the wireless MESH network can be achieved, a process for acquiring the device capability information can be simplified, and efficiency for acquiring the device capability information is improved.

On this basis, as shown in fig. 7, when the network node device 300 (i.e., the network node device with which the mobile terminal is currently associated) receives the networking request information sent by the mobile terminal 500, the device information of the first network node device scanned by the mobile terminal 500 may be acquired, then at least one candidate networking device is determined based on the device information of the first network node device and the previously acquired device capability information set, and then the networking performance evaluation index of the candidate networking device is determined based on the device capability information of the candidate networking device, so that a target networking device is determined from the at least one candidate networking device based on the networking performance evaluation index of the candidate networking device, and the target networking device is recommended to the mobile terminal 500 for association.
