Through distributed networking, the requirements of broadband internet access, video entertainment and the like of home users can be met, and the problems of Wi-Fi full-house coverage, high-speed connection and seamless roaming are solved.

Currently, the home wireless networking full coverage and seamless roaming are mainly realized by the easy mesh technology. At present, the EasyMesh protocol defines two networking joining mechanisms of an EasyMesh network AP: one is networking and joining through a Wi-Fi Protected Setup (WPS for short) key; one is networking joining via the Data Provisioning Protocol (DPP). The WPS key networking joining mechanism is defined in easy mesh R1, and needs to be triggered by key processing in a main route (Controller-AP) and a sub-route (Agent-AP) within a specified time and associated for multiple times; the networking is triggered through the DPP protocol defined in EasyMesh R3, and it is also necessary to scan the two-dimensional code, and interact through using the mobile phone APP, or interact with the authentication information through bluetooth, Near Field Communication (NFC for short), or other methods. Both mechanisms are not very convenient, fast and flexible, and the networking time is slow, so that the experience for users is poor.

[ summary of the invention ]

Preferably, the credential information is encrypted during the transmission process, which specifically includes: the main route encrypts the sent networking adding certificate information, and the key comprises the MAC address and the random key of the target sub-route, so that the equipment which is not expected to be accessed cannot know the correct key and cannot be accessed to the network; and after receiving the networking joining voucher information sent by the main route through multicast, the sub-route decrypts the joining voucher information and verifies and judges the validity of the networking joining voucher information.

Preferably, when the main route and the sub-route use non-PCB antennas, the specific way of generating the event of relatively large change in RSSI is that the antennas of the networking devices are close to each other, and the antenna of the main route is moved in the area of different signal strengths in the wireless signal field of the sub-route.

Preferably, when the sub-route is not networked with the main route, the specific way to generate the event of the strong RSSI change relatively greatly is that the sub-route periodically adjusts the wireless output power intensity thereof.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

The present invention is a system structure of a specific function system, so the functional logic relationship of each structural module is mainly explained in the specific embodiment, and the specific software and hardware implementation is not limited.

In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other. The invention will be described in detail below with reference to the figures and examples.

Example 1:

the EasyMesh network belongs to one of wireless Multi-AP networking, so related messages and chips of an 802.11 protocol can be used for corresponding processing. In this embodiment, the detection of a relatively large-amplitude change event of strong RSSI can be realized by using a driving layer in the AP device in combination with a wifi chip to detect a Received Signal Strength Indication (RSSI), and a process for adding AP networking is automatically triggered without additionally using a WPS button or an APP or other modes for manual triggering.

As shown in fig. 1, the method for adding AP networking in an EasyMesh network provided by the embodiment of the present invention specifically includes the following steps:

step 101: a relatively large-amplitude variation event of strong RSSI is generated between the Controller-AP and the Agent-AP having the same vendor identification code.

In this embodiment, in order to avoid that mutual identification cannot be performed during pairing or normal pairing cannot be performed after networking, the Controller-AP and the Agent-AP used for pairing need to use devices of the same manufacturer. In practical use, manufacturers of Controller-APs and Agent-APs attempting to join a networking can be identified by using a Vendor Specific field (Vendor identification code, hereinafter referred to as Vendor id) of 802.11 Management-Beacon, fig. 2 is a field schematic diagram of a Beacon frame, and devices having the same Vendor id come from the same Vendor and can be identified with each other for networking. After the Agent-AP is started, the Beacon frame is periodically multicast and sent according to the protocol requirement.

The wifi chip all has the function of test signal intensity in every wireless AP equipment, and under the condition of normal use, in order to guarantee communication quality, the RSSI of equipment can remain stable high strength usually, can not appear changing by a wide margin in the short time. Therefore, in the solution provided in this embodiment, a relatively large change in the strong RSSI may be generated in various ways as a condition for triggering the joining of the networking. On a Controller-AP and an Agent-AP which need to be networked, beacon frame monitoring detection on an air interface is realized through a raw sock, and frequent and rapid RSSI value change between the Controller-AP and the Agent-AP at a close distance is detected, namely a strong RSSI relatively large-amplitude change event occurs. In different specific implementation scenarios, the generation mode of the event with the strong RSSI change is different, so that both the Controller-AP and the Agent-AP may detect the event. In this embodiment, since the Controller-AP is the initiator of the networking, the Controller-AP needs to detect the event as a trigger condition for initiating the networking. In the specific implementation process, the relatively large change of the strong RSSI can be completed through simple approaching rotation among different equipment antennas, and the signal sending intensity can also be adjusted by the equipment. For example: when the sub-route is not networked with the main route, the software is used for adjusting the sending power percentage setting of the sub-route, so that the wireless output power intensity of the sub-route is periodically adjusted, and even if the Agent-AP is not moved, the RSSI detected by the Controller-AP and the RSSI of the Agent-AP are greatly changed. Preferably, in order to ensure the communication quality during networking interaction and the communication quality after networking, after the event is detected by the main route, the main route initiates the credential information interaction with the sub-route, and after the sub-route receives the event, the sub-route adjusts the sending power percentage of the sub-route to be set as a normal value through software.

Step 102: and after the event is detected, the Controller-AP initiates the information interaction of the added certificate with the Agent-AP.

After a relatively large-amplitude change event of strong RSSI between the Controller-AP and the Agent-AP is detected, the networking joining action is completed through the interaction of the joining voucher information. In a specific implementation, the added credential information includes a Service Set Identifier (SSID), so that the Agent-AP can complete networking authentication. And initiating the credential adding interaction between the Controller-AP and the Agent-AP, and after receiving the credential adding information, the Agent-AP replies correspondingly, performs corresponding setting according to the credential adding information, and accesses the network where the Controller-AP is located. In actual use, the Controller-AP and the Agent-AP which are not networked cannot exchange messages one to one, so that the multicast messages can be used when the access credential information interaction is performed, and the Controller-AP and the Agent-AP analyze the content of the multicast messages to obtain corresponding information. Furthermore, in order to avoid that the equipment which does not need to be connected with the networking receives the joining certificate information, the multicast joining certificate information can be encrypted, the key is related to the MAC address of the target site, the equipment which does not need to be connected cannot decrypt, and malicious equipment is prevented from intercepting the joining certificate information to enter the networking. The Beacon frame carries the source MAC address of the sender, and the Controller-AP can acquire the MAC address of the Agent-AP through the Beacon frame sent by the target Agent-AP to generate a key. When the Controller-AP receives Beacon frames sent by target Agent-APs with different MAC addresses, networking events of the target Agent-APs corresponding to each MAC address can be processed in a time-sharing mode. When the multicast join voucher information is encrypted, the join voucher information also needs to include a pre-shared key (abbreviated as PSK) and an encryption mode.

Step 103: and the Agent-AP opens the networking authentication association with the Controller-AP, and adds the networking authentication association into an EasyMesh network where the Controller-AP is located.

In step 102, the join credential information sent by the Controller-AP includes an SSID, and the SSID technology can divide a wireless lan into several sub-networks requiring different authentication, each sub-network requires independent authentication, and only a user who passes the authentication can enter the corresponding sub-network, thereby preventing unauthorized users from entering the network. After the Agent-AP acquires the SSID required by the joining of the networking through the joining credential information, the Agent-AP can complete backhaul network authentication association through an inter-AP networking interface in the EasyMesh network according to the identity verification information. Furthermore, in order to make the networking process more convenient and faster, after the authentication association is completed, the Controller-AP and the Agent-AP can also complete automatic configuration through configuration data interaction, so that the networking efficiency is further improved.

After the steps 101 to 103 provided in this embodiment, a networking join event of the Controller-AP and the Agent-AP may be triggered by a strong RSSI large-amplitude change event, so as to complete a networking process, thereby improving networking efficiency and user experience.

When detecting the relatively large-amplitude change event of the strong RSSI among the devices, in order to accurately select the device needing networking and avoid triggering the unnecessary networking join event due to the unexpected relatively large-amplitude change event of the strong RSSI such as network failure or device configuration adjustment, when detecting the event, firstly, according to step 101, judging whether the event is a Controller-AP and an Agent-AP with the same VendorD through the VendorD of the Beacon frame, judging whether the Agent-AP is already networked and joined into the network where the Controller-AP is located by the Controller-AP or not, initiating the interaction in step 102 only for the Agent-AP device which is not networked, and if the Agent-AP device is already networked, ignoring the event. If not, the beacon frame of the Agent-AP on the air interface is monitored and detected through the raw sock, a relatively large-amplitude change event of the strong RSSI is obtained, networking interaction processes in the step 102 and the step 103 are triggered after the event is obtained, and interaction is sent to the Agent-AP through the Controller-AP. And after the Agent-AP receives the networking adding voucher information sent by the Controller-AP, setting the networking adding voucher information to take effect on the Agent-AP, and automatically accessing the backhaul network of the Controller-AP.

Further, after the Agent-AP opens the networking authentication association with the Controller-AP, the Controller-AP starts to configure the Agent-AP, and the Controller-AP and the Agent-AP complete the interaction of the automatic configuration message and complete the synchronization of the configuration information. The Agent-AP sets networking adding voucher information on the Agent-AP, such as SSID, PSK, encryption mode and other items capable of being automatically configured, each configured item takes effect immediately and automatically accesses a backhaul network of the Controller-AP, and networking addition of the Agent-AP in the easy mesh network is achieved. The Agent-AP can be rapidly and conveniently added into the EasyMesh network, the user experience is improved, and the networking adding mechanism of the existing EasyMesh network AP is increased.

In a general implementation scenario, in the interaction process of the Controller-AP and the Agent-AP completing the automatic configuration message, as shown in fig. 3, a common configuration process is as follows, and specific configuration item content may also be added or adjusted according to actual needs.

Step 201: the Agent-AP initiates an AP-Autoconfiguration Search message to the Controller-AP. The Agent-AP sends out an automatic configuration search message and provides a synchronous request of the automatic configuration information to the Controller-AP.

Step 202: the Controller-AP responds with an AP-Autoconfig Resp to the Agent-AP. And after the Controller-AP receives the synchronous request message of the Agent-AP, returning an automatic configuration search response message to inform the Agent-AP to start executing automatic configuration.

Step 203: the Agent-AP sends out AP-Autoconfig WSC M1 to the Controller-AP. The Agent-AP sends out an automatic configuration wireless simple configuration request configuration issuing message and requests the Controller-AP for data used for automatic configuration.

Step 204: the Controller-AP responds to the Agent-AP with AP-Autoconfig WSC M2(s) w/Multi-AP strategies & options strategies. And after receiving the request, the Controller-AP returns an automatic configuration wireless configuration issuing message, and the Agent-AP completes configuration according to the configuration item data in the message.

After the steps 201 to 204, Agent-AP completes the frontaul wireless configuration information synchronization of Controller-AP without additional operation of the user, the whole EasyMesh network has the same SSID and password, and when roaming on different APs in the network through the Controller-AP and the station terminal of Agent-AP connected to the network, the same network is used, thereby realizing seamless roaming based on 802.11k/v/r in the whole EasyMesh network, and improving user experience.

When the Controller-AP initiates the information interaction with the Agent-AP, the added certificate needs to contain SSID, PSK and encryption mode, and possibly other information needed by interaction, so that a single multicast message cannot be used for transmission. In the specific implementation, the Controller-AP sends at least one group of multicast messages to the Agent-AP.

Furthermore, when the credential information is added for interaction, a safe encryption mode is used in the transmission process of the credential information. The joining credential information is encrypted during the delivery process, and the encrypted key is associated with the MAC address of the destination station. Specifically, the Controller-AP encrypts the sent networking access credential information, and the key includes the MAC address and the random key of the target Agent-AP, so that the device which is not expected to access cannot know the correct key and cannot access the network. In an actual scenario, an appropriate encryption mode, such as DES, AES, RSA, key string, etc., may be selected as needed. In this embodiment, it is preferable to perform Encryption processing using Advanced Encryption Standard (AES) 128, which is 128 bits Advanced Encryption Standard, in consideration of Encryption effect, transmission consumption, and the like. As shown in fig. 4, the plaintext of the credential information including the encryption information includes: SSID information used for identity authentication, PSK information and encryption mode information used for encryption and decryption, and a checksum used for data integrity check. In a specific implementation, the check method may select a suitable check method according to transmission needs and protocol specifications, such as MD5 check, cyclic redundancy check, and the like.

In the case of non-networking, the Controller-AP and the Agent-AP cannot directly finish the transmission of the key through interaction. In a wireless network, any frame sent by other devices in the same channel cannot know the content of the delivered data without knowing the key, but still has some available information, such as the length of the frame, and part of the data of the frame header, such as the source MAC and the destination MAC of the frame. As shown in fig. 5, the 16-byte key used in the AES128 encryption scheme may be composed of the MAC address of the target Agent-AP (6 bytes), a random key (2 bytes), and fixed 8-byte fixed data specified by the protocol. When the information interaction of the added certificate is carried out, the multicast message is sent out in an encrypted manner, and the equipment which is not expected to be accessed cannot obtain a correct key, so that the network cannot be accessed.

In specific implementation, the original format of the multicast message may be used to carry the joining credential information and the key information. In this embodiment, networking addition credential information is carried in the last 2 bytes of the target multicast address in each multicast message, and the networking addition credential information transmits the last two bytes of the multicast address of each multicast message shown in part in a ciphertext splitting manner. As shown in fig. 6, a series of multicast messages are used for transmitting join credential information, where each block in the figure represents one multicast message, and the join credential information in fig. 4 is encrypted by using the key in fig. 5, and then is split into the last 2 bytes of the target multicast address in each multicast message for transmission.

After the Agent-AP receives the networking joining voucher information sent by the Controller-AP through multicast, the Agent-AP also needs to decrypt the joining voucher information and verify and judge the validity of the networking joining voucher information. Specifically, the Agent-AP extracts the split added credential information in 2 bytes after each multicast packet, combines the extracted added credential information into a complete added credential information ciphertext, generates a decryption key according to a defined encryption and decryption method and using the received random key and other information (the MAC address (6 bytes) of the target Agent-AP and fixed 8-byte fixed data specified by a protocol), decrypts the complete added credential information to obtain the added credential information plaintext as shown in fig. 4, verifies the added credential information according to the checksum field therein, and verifies and judges the validity of the added credential information by networking. And after confirming that the added certificate information is valid, finishing the networking adding process by using SSID, PSK and encryption mode information in the added certificate information.

In the specific implementation process of this embodiment, the relatively large change event of the strong RSSI between the Controller-AP and the Agent-AP in step 101 may be generated in various ways according to the device characteristics and the actual needs. When the Controller-AP and the Agent-AP use non-PCB antennas, the signal radiation intensity distribution of the antennas is similar to an apple type, as shown in a vertical section diagram of FIG. 7, the signal of a concave space at the central axis of an apple is weakest, the signal intensity in the oval ranges at the two sides is stronger, and the difference of the signal intensity can be 20db at most. According to the test result in the actual use scene, when the Controller-AP and the Agent-AP with the same VendorId approach to each other to about 0.5-1 m and start to rotate relatively, the large change of the strong RSSI can be detected on the Controller-AP and the Agent-AP. When the Controller-AP and Agent-AP antennas are vertical to each other, the strength of the signals detected by the Controller-AP and the Agent-AP antennas is weakest; when the Controller-AP antenna and the Agent-AP antenna are parallel to each other during rotation, the strength of the signals detected by the Controller-AP antenna and the Agent-AP antenna is the strongest. For example, in a certain practical scenario, the measured strong RSSI signal strength interval is-15 dbm to-30 dbm, and the signal strength variation range is 6dbm to 12dbm, which can be monitored by using the driving layer of the AP device in cooperation with the function of testing the signal strength of the wifi chip in the device. Therefore, in the preferred solution of this embodiment, the specific way of generating the event of relatively large-amplitude change of strong RSSI is to make the antennas of the networking devices close to each other, and make the antenna of the main route move in the areas with different signal strengths in the wireless signal field of the sub-route. In actual use, the Controller-AP and the Agent-AP can be simply close to each other, and the Agent-AP equipment is rotated or shaken, so that the strength of the signal received by the antenna of the Controller-AP can be changed. The method comprises the steps that a Controller-AP and an Agent-AP which need to be networked by an EasyMesh network are close to each other and rotate, so that an antenna of the equipment moves between areas with different signal intensities in a signal radiation range of another equipment, the Controller-AP and the Agent-AP can detect an event with strong RSSI (received signal strength indicator) relative large-amplitude change, a networking adding process is triggered, and the Agent-AP can be quickly and conveniently added into the EasyMesh network. On the other hand, when the Controller-AP and the Agent-AP use PCB antennas, since signal radiation intensity distributions of different PCB antennas have different characteristics, there is no very consistent operation rule for operations of specific modes that generate events with relatively large changes in strong RSSI, and it is necessary to refer to the operation mode of the non-PCB antenna and specify the operation mode according to the antenna characteristics, such as close rotation, relative lateral or longitudinal movement, close distance, and the like, so that the antenna of the device moves between positions with different signal intensities in the antenna signal radiation field to generate changes in strong RSSI signals.

The method for adding AP networking in an EasyMesh network provided in this embodiment is based on two networking addition mechanisms of an AP in an EasyMesh network defined by the existing EasyMesh protocol: the method comprises the following steps of performing networking joining through a WPS key and performing networking joining through a DPP protocol, and additionally, adding a new networking joining mechanism: the Controller-AP and the Agent-AP in the EasyMesh network can realize that the Agent-AP can be quickly and conveniently added into the EasyMesh network by detecting the relatively large-amplitude change event of the strong RSSI among the controllers-AP and the Agent-AP. Furthermore, the operation steps required by networking are further simplified through steps of automatic configuration and the like. In actual use, a user can only achieve the purpose of enabling AP in an easy mesh network to be more convenient, quicker and more flexible through simple approaching rotation, the networking time is quicker, and the user experience is better.

Example 2:

on the basis of the method for adding AP networking in the EasyMesh network provided in embodiment 1, the present invention also provides a system for adding AP networking in the EasyMesh network, which is capable of implementing the method.

Fig. 8 is a schematic diagram of a system architecture according to an embodiment of the present invention. The system comprises a Controller-AP and an Agent-AP which need to be networked and have the same VendorId. The Controller-AP and the Agent-AP both belong to AP devices, and all devices include wifi chips on the driver layer that can detect the relatively large-amplitude event of the strong RSSI, so that the method provided in embodiment 1 can be used to trigger the adding process of the networking by detecting the relatively large-amplitude event of the strong RSSI therebetween, thereby completing the process of the networking.

In the specific implementation process, the Controller-AP and the Agent-AP trigger the adding process of the networking by detecting a relatively large-amplitude change event of the strong RSSI in step 101. And after the networking joining process is triggered, the Controller-AP sends joining voucher information to the Agent-AP according to the step 102. After receiving the added certificate information, the Agent-AP performs identity verification by using the SSID, PSK and encryption mode information according to step 103, completes networking authentication association, and adds the information into the easy mesh network where the Controller-AP is located. Further, the request, issue and acquisition of the automatic configuration information can be realized between the Controller-AP and the Agent-AP according to the automatic configuration information interaction process of the steps 201 to 204, and the Agent-AP completes the automatic configuration process according to the automatic configuration information issued by the Controller-AP.

Further, in a scenario where the Controller-AP and the Agent-AP use non-PCB antennas, as shown in fig. 9, a relatively large-amplitude variation event of strong RSSI can be generated by the close rotation of the Controller-AP and the Agent-AP antennas. When the antennas of the two devices are close to each other and rotate from being parallel to being perpendicular to each other, the signal radiation intensity section diagram of the antennas is changed from the state of fig. 10 to the state of fig. 11, the antennas move through different positions of the signal radiation area of the opposite antenna, and signals with different intensities are received, so that the wifi chip detects a plurality of signals with different intensities in a short time period, and a relatively large-amplitude change event of strong RSSI is generated. For a user, WPS key processing triggering and multiple association are not needed within a set time, extra mobile phone APP or Bluetooth authentication is not needed, and networking operation can be conveniently and rapidly completed only by enabling Controller-AP and Agent-AP equipment needing networking to be close to each other and rotating relatively.
