Description

Connection method of wireless network bridge, configuration equipment, AP and CPE

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a connection method, configuration equipment, an AP (access point) and a CPE (customer premises equipment) of a wireless network bridge.

Background

Wireless bridges, i.e., bridges of wireless networks, utilize wireless transmission to bridge communications between two or more networks. The point-to-multipoint wireless bridge erecting scheme is widely applied, and can be applied to a wireless campus network, a forestry protection local area network, a public security traffic local area network, a construction site local area network and the like.

In a Point-to-multipoint bridging scenario, when a Wireless bridge applied in an AP (Wireless Access Point) mode is damaged, a constructor is required to take a new AP to replace the damaged AP. At this time, the constructor is required to go to an actual installation location of the wireless bridge applied as a CPE (Customer Premise Equipment) mode, and operate the CPEs one by one, thereby implementing bridging between the CPEs and the new AP.

In a real scene, the actual installation position of the CPE is distributed over a tower crane, a street lamp, a monitoring pole, a roof, a mountain top and the like, and the CPE can be operated only when the CPE reaches a certain height manually. Thus, a pair of three bridges requires 3 CPEs to operate and a pair of five bridges requires 5 CPEs to operate, which increases both workload and risk. In summary, when an AP is damaged, a fast connection between the new AP and the CPE cannot be achieved.

Disclosure of Invention

The application provides a connection method, configuration equipment, an AP and a CPE of a wireless network bridge, which are used for realizing the quick connection between the new AP and the CPE.

In a first aspect, an embodiment of the present application provides a connection method for a wireless bridge, which is applied to a configuration device, and the method includes: receiving a first replacement notification aiming at a first AP and sent by a third wireless Access Point (AP), wherein the first replacement notification is sent by the third AP after receiving a first replacement instruction sent by the first AP and establishing wireless connection with a first Customer Premise Equipment (CPE); if the identifier of the first AP is found from the corresponding relationship among the AP identifier, the CPE identifier and the SSID, replacing the identifier of the first AP with the identifier of the third AP, and acquiring a first SSID corresponding to the identifier of the third AP from the corresponding relationship, wherein the first SSID is a bridging signal obtained by modifying a bridging signal released externally respectively after the first AP and the first CPE establish wireless connection; sending a first scanning request to the third AP so that the third AP searches for a bridging signal in the environment and returns a first scanning result; if the first scanning result is determined to include the first SSID, sending a first configuration request carrying the first SSID to the third AP, so that the third AP establishes a wireless connection with the first CPE after changing an externally released bridging signal to the first SSID.

Based on this solution, for a combination of a first AP and a first CPE that establish a wireless connection, if the first AP needs to be replaced due to a failure of the first AP, or the first AP needs to be replaced based on a specific requirement, the first AP sends a replacement instruction (i.e. a first replacement instruction) to a replacement AP that is a third AP, so that the third AP can send a replacement notification (i.e. a first replacement notification) to the configuration device based on the replacement instruction, so that if the configuration device can find an identifier of the first AP from a corresponding relationship between an AP identifier, a CPE identifier and an SSID, the configuration device can replace the identifier of the first AP with the identifier of the third AP and obtain a first SSID (i.e. an original bridge signal that the first AP releases to the outside) corresponding to the identifier of the third AP from the corresponding relationship, and then, the configuration device sends a scanning request (i.e. a first scanning request) to the third AP, therefore, the third AP may search for the bridging signal in the environment, and return the search result (i.e., the first scanning result) to the configuration device, and if the configuration device determines that the first SSID exists in the search result, the configuration device may send the first configuration request carrying the first SSID to the third AP, so that the third AP may reestablish the connection with the first CPE after changing the bridging signal released by the third AP from the outside to the first SSID. In the scheme, after the wireless connection is established for any pair of AP and CPE establishing the wireless connection in the same area, the bridge signals released by the AP and CPE establishing the wireless connection are changed, so that the bridge signals released by the AP and CPE establishing the wireless connection are different pairwise, and the corresponding relation is established between the combination of any pair of AP and CPE and the changed bridge signals and is stored.

In one possible implementation method, a second replacement notification sent by a second CPE and addressed to the first CPE is received, where the second replacement notification is sent by the second CPE after receiving a second replacement instruction sent by the first CPE that establishes a wireless connection with the first AP; if the identifier of the first CPE is found from the corresponding relationship, replacing the identifier of the first CPE with the identifier of the second CPE, and acquiring the first SSID corresponding to the identifier of the second CPE from the corresponding relationship; sending a second scanning request to the second CPE so that the second CPE searches for a bridging signal in the environment and returns a second scanning result; if the second scanning result is determined to include the first SSID, sending a second configuration request carrying the first SSID to the second CPE, so that the second CPE establishes wireless connection with the first AP after changing the externally released bridging signal into the first SSID.

Based on this solution, for a combination of a first AP and a first CPE that establish a wireless connection, if the first CPE needs to be replaced due to a failure of the first CPE or the first CPE needs to be replaced based on a specific requirement, the first CPE sends a replacement instruction (i.e. a first replacement instruction) to a replacement CPE, such that the second CPE can send a replacement announcement (i.e. a second replacement announcement) to a configuration device based on the replacement instruction, so that the configuration device can, if the identity of the first CPE can be found from a corresponding relationship between the AP identity, the CPE identity and the SSID, replace the identity of the first CPE with the identity of the second CPE and obtain, from the corresponding relationship, a first SSID (i.e. an original bridge signal released by the first CPE) corresponding to the identity of the second CPE, and then the configuration device sends a scanning request (i.e. a second scanning request) to the second CPE, therefore, the second CPE can search for the bridging signal in the environment and return the search result (i.e., the second scanning result) to the configuration device, and if the configuration device determines that the first SSID exists in the search result, the configuration device can send a second configuration request carrying the first SSID to the second CPE, so that the second CPE changes the bridging signal released by the second CPE to the first SSID and then reestablishes the connection with the first AP. In the scheme, after the wireless connection is established for any pair of AP and CPE establishing the wireless connection in the same area, the bridge signals released by the AP and CPE establishing the wireless connection are changed, so that the bridge signals released by the AP and CPE establishing the wireless connection are different pairwise, and the corresponding relation is established between the combination of any pair of AP and CPE and the changed bridge signals and is stored.

In a second aspect, an embodiment of the present application provides a connection method for a wireless bridge, where the method is applied in a first AP, and the method includes: after establishing wireless connection with the first CPE, changing the bridging signal released by the first CPE to a first SSID; the first SSID is different from a second SSID released by any AP in the area where the first AP is located; sending a bridging signal change instruction carrying the first SSID to the first CPE so that the first CPE changes a bridging signal released by the first CPE to the first SSID; sending the identifier of the first AP, the identifier of the first CPE and the first SSID to configuration equipment, so that the configuration equipment correspondingly stores the identifier of the first AP, the identifier of the first CPE and the first SSID in the corresponding relation of the AP identifier, the identifier of the CPE and the SSID; sending a first replacement instruction to a third AP, so that the third AP sends a first replacement notification for the first AP to the configuration device, after the configuration device finds the identifier of the first AP from the corresponding relationship, the identifier of the third AP replaces the identifier of the first AP, and obtains the first SSID corresponding to the third AP from the corresponding relationship, sending a first scanning request to the third AP through the configuration device, searching for a bridging signal in an environment by the third AP and returning a first scanning result, after the configuration device determines that the first scanning result includes the first SSID, sending a first configuration request carrying the first SSID to the third AP, and after the third AP changes an externally released bridging signal to the first SSID, establishing a wireless connection with the first CPE.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In real life, for the erection scheme of the point-to-multipoint wireless bridge, the wireless bridge is used in many scenes, for example, a large construction site needs to be monitored in real time for specific construction conditions in the construction process so as to prevent accidents; for another example, an underground parking lot also needs to be monitored in real time for specific parking conditions, so that parking space information of the parking lot, including the number of empty parking spaces and specific empty parking space positions, can be displayed externally. By way of example, in the embodiments of the present application, a multipoint wireless bridge is described as an example at a large construction site S.

As shown in fig. 1, a schematic diagram of a possible system architecture provided for the embodiment of the present application includes one or more APs, one or more CPEs, and a configuration device (not shown in the figure). Optionally, the system architecture further comprises a first device and a second device (not shown in the figure). As an example, the system architecture includes 2 APs and 7 CPEs as an example; as an example, the system architecture is designed to monitor the construction condition of a large construction site S in real time.

When the system architecture includes a plurality of APs, for any one of the APs, on one hand, it may establish a connection with one or more CPEs in a wireless manner, so as to receive data sent by the one or more CPEs connected to the AP; on the other hand, it may establish a connection with the second device, either by wire or wirelessly, for sending data it receives from the CPE to the second device for processing by the second device. For example, when the data sent by the CPE is a video, the processing manner of the data by the second device includes displaying the video, and at this time, the second device may be a video display tool such as a video display.

When the system comprises a plurality of CPEs, for any one of the CPEs, on one hand, the CPE can establish connection with the first equipment in a wired or wireless mode and is used for receiving data sent by the first equipment; on the other hand, it may establish a connection wirelessly with an AP for transmitting data it receives from the first device to the AP. For example, when the first device is an image/video capture tool such as a camera, the data received by the CPE is data in a format such as an image or a video.

When a wireless bridge is deployed for a certain domain, one or more APs may be set, which is not specifically limited in the present application; further, the number of CPEs establishing wireless connection with the same AP may be one or more, and is not specifically limited in this application. Referring to fig. 1, the description of fig. 1 is as follows:

for a region, 2 APs may be set in the region, the 2 APs are respectively identified as AP1 and AP2, and the 2 APs are close to or the same distance from the second device; further, the number of the CPEs establishing wireless connection with the AP1 is set to 3, and the 3 CPEs are respectively identified as CPE1-1, CPE1-2 and CPE1-3 and are arranged in different areas of the region, wherein an area where any one of the CPEs is located is simultaneously provided with a first device; based on the same reasoning, the number of CPEs establishing wireless connection with the AP2 is set to 4, and the 4 CPEs are respectively identified as CPE2-1, CPE2-2, CPE2-3 and CPE2-4 and are located in different areas of the region, wherein an area where any one of the CPEs is located is simultaneously provided with a first device.

For example, in order to realize the monitoring to construction site S, the staff can install the camera in position such as tower crane, beacon in the construction site, the camera is used for monitoring the construction condition of tower crane, beacon surrounding environment. Under the general condition, the positions such as tower crane, beacon are far away from the monitoring room, and the area range to be monitored is large, so in order to realize that the construction condition of the construction site can be looked up by the staff in the monitoring room, the system architecture shown in fig. 1 can be adopted, namely, the video data of the construction condition collected by the cameras arranged at the positions such as tower crane, beacon can be visually displayed on the video display of the monitoring room in a mode of erecting a wireless network bridge, and the construction condition of the construction site can be conveniently looked up by the staff. As shown in fig. 1, the locations of CPE1-1, CPE1-2, and CPE1-3 are also the installation locations of the cameras, so that each camera can transmit the video data of the construction situation of the surrounding environment collected by itself to the CPE connected to itself, that is, CPE1-1, CPE1-2, and CPE1-3 can respectively acquire the video data collected and transmitted by the camera connected to itself, then any one of CPE1-1, CPE1-2, and CPE1-3 transmits the acquired video data to AP1 through the wireless connection between itself and AP1, after the AP1 acquires the video data transmitted by the CPE, the AP1 transmits the acquired video data to the video display through the connection between itself and the video display, so that the video display can visually display the construction situation monitored by the cameras at the locations of CPE1-1, CPE1-2, and 1-3, the construction site S is convenient for monitoring by workers; based on the same reasoning, the locations of the CPEs 2-1, 2-2, 2-3 and 2-4 are also the installation locations of the cameras, so that each camera can transmit the video data of the construction situation of the surrounding environment collected by itself to the CPE connected to itself, that is, the CPE2-1, the CPE2-2, the CPE2-3 and the CPE2-4 can respectively acquire the video data collected and transmitted by the camera connected to itself, then any one of the CPE2-1, the CPE2-2, the CPE2-3 and the CPE2-4 transmits the acquired video data to the AP2 through the wireless connection between itself and the AP2, and after the AP2 acquires the video data transmitted by the CPE, the AP2 transmits the acquired video data to the video display through the connection between itself and the video CPE, so that the video data pairs 2-1, 2-1 and the video data are transmitted, Construction conditions monitored by the cameras at the positions of the CPE2-2, the CPE2-3 and the CPE2-4 are visually displayed, so that workers can conveniently monitor the construction site S.

For the wireless bridging process between AP and CPE, taking wireless bridging between AP1 and CPE1-1, CPE1-2 and CPE1-3, and wireless bridging between AP2 and CPE2-1, CPE2-2, CPE2-3 and CPE2-4 as examples, the following description can be made:

1. after installing the AP1 and the AP2 purchased from the same manufacturer according to the preset position, the worker powers on the AP1 and the AP2, and the AP1 and the AP2 default to release the bridging signal with the same bridging name to the outside, wherein the bridging name can be set in factory settings and is set as SSID 1;

2. after the working personnel install the CPE1-1, the CPE1-2 and the CPE1-3 according to the preset positions, the working personnel power up the CPE1-1, the CPE1-2 and the CPE1-3, then internal initialization programs of the CPE1-1, the CPE1-2 and the CPE1-3 are triggered, and bridging signals in a search environment are defaulted; since the bridging signal of the SSID1 released by the AP1 and the bridging signal of the SSID1 released by the AP2 exist in the environment, but since the AP1 matches the installation locations of the CPEs 1-1, 1-2 and 1-3 and the AP2 does not match the installation locations of the CPEs 1-1, 1-2 and 1-3, the signal strength of the bridging signal of the SSID1 released by the AP1 searched by the CPEs 1-1, 1-2 and 1-3, respectively, will be stronger than that of the bridging signal of the SSID1 released by the AP2, thereby realizing wireless bridging between the CPEs 1-1, 1-2 and 1-3, respectively, and the AP 1. Similarly, wireless bridging between CPE2-1, CPE2-2, CPE2-3, and CPE2-4, respectively, and AP2 may also be implemented.

It is noted that after CPE1-1, CPE1-2, and CPE1-3 are connected to AP1, respectively, the internal programs of CPE1-1, CPE1-2, and CPE1-3 may be triggered again, which are used to indicate that when AP1 fails or needs to be replaced by another AP for other reasons, CPE1-1, CPE1-2, and CPE1-3 will be unable to connect to the AP for a short period of time, and if the CPE in an unlinked state searches for a bridge signal from the environment again, CPE1-1, CPE1-2, and CPE1-3 can only connect based on the bridge signal of the SSID1 connected this time.

In real life, the situations of CPE damage and AP damage are inevitable.

Taking the CPE1-1 damaged as an example, a worker is required to take a new CPE to replace the damaged CPE1-1, and the installation position of the new CPE is required to be identical to that of the damaged CPE1-1 at the time of replacement, and if the installation position is different, the installation error is required to be controlled within an acceptable range. After the new CPE is installed, the new CPE is powered on, an internal program of the new CPE is triggered, a bridge signal in a search environment is set to be default, based on the same reason as the installation step of the CPE1-1, the new CPE can be connected to the AP1, wireless bridge connection between the new CPE and the AP1 can be achieved, the video data received by the new CPE and sent from the camera at the position of the new CPE can be sent to the AP1 by the new CPE, the video data are sent to the video display by the AP1, and therefore a monitoring person can observe construction conditions collected by the camera at the position of the new CPE on the video display again.

Taking the case of a damaged AP1, a worker is required to take a new AP (purchased from the same manufacturer as AP 1) to replace the damaged AP1, and the installation position of the new AP is required to be identical to that of the damaged AP1, and if different, the installation error needs to be controlled within an acceptable range. After the new AP is installed, the new AP is powered on, and the new AP will default to release the bridging signal of SSID1 externally. It should be noted that, during the damage of the AP1, the CPEs 1-1, 1-2 and 1-3, which originally establish wireless connection with the AP1, will be in an unlinked state, and when the CPEs 1-1, 1-2 and 1-3 find their own wireless bridge links to be disconnected, they can trigger their internal search procedure for the bridge signal of the SSID1 that may exist in the environment, that is, the CPEs 1-1, 1-2 and 1-3 will search for the bridge signal existing in the environment according to the bridge signal that has been wirelessly connected with their latest, in other words, the CPEs 1-1, 1-2 and 1-3 will remember the bridge signal that they have connected last time, and when they will use their latest bridge signal as the search after the unlinked state, they will attempt to find the same bridge signal from the environment, to enable its connection with it. When CPE1-1, CPE1-2, and CPE1-3 search for the bridging signal of SSID1, CPE1-1, CPE1-2, and CPE1-3 will automatically connect to AP2 because the environment has the bridging signal of SSID1 released by AP2 (although the signal strength is weak). However, due to the mismatch of the installation positions of the CPEs 1-1, 1-2, 1-3 and the AP2, the AP2 cannot receive the video data transmitted by the CPEs 1-1, 1-2 and 1-3, in other words, the construction conditions collected by the cameras at the positions of the CPEs 1-1, 1-2 and 1-3 cannot be displayed on the video display of the monitoring room. Thus, after the new AP is powered on, although the bridging signal of SSID1 is released externally, CPE1-1, CPE1-2, and CPE1-3, which have maintained wireless bridging with AP2, do not automatically disconnect from AP2, and more precisely, CPE1-1, CPE1-2, and CPE1-3, which have established wireless bridging with AP2, are not aware at all that a new AP has replaced the original AP 1. In the event of a breakdown of AP1, therefore, after the worker replaces it with a new AP, it also requires personnel to reach the installation locations of CPE1-1, CPE1-2, and CPE1-3 in the field, manually disconnect their wireless connections from AP2, after powering CPE1-1, CPE1-2 and CPE1-3 back up, they will search for bridging signals present in the environment from this bridging signal of their own stored SSID1, and after searching for a strong (bridge signal released by new AP) and a weak (bridge signal released by AP 2) bridge signal both of SSID1, the CPEs select the APs with stronger signal strength to connect, that is, the CPE1-1, the CPE1-2 and the CPE1-3 can be connected to new APs respectively, so as to achieve the goal of replacing the AP1 when the AP1 fails. From the above, when an AP is damaged, a worker needs to reach the installation location of the CPE in the field, and the replacement of the failed AP can be implemented after the CPE is operated, which increases the workload of the worker and increases the risk.

In view of the foregoing problems, an embodiment of the present application provides a connection method for a wireless bridge, which is applied in a configuration device, and as shown in fig. 2, the method includes:

step 201, receiving a first replacement advertisement for a first AP sent by a third AP, where the first replacement advertisement is sent by the third AP after receiving a first replacement instruction sent by the first AP establishing a wireless connection with a first CPE.

In this step, the first replacement instruction may be sent from the first AP to the third AP when the first AP determines that the first AP disconnects the wireless connection with the first CPE, or the first replacement instruction may be based on some specific requirements, such as a requirement for product upgrade, that the first AP needs to be upgraded, and at this time, the first replacement instruction is sent to the third AP through the first AP, which is not specifically limited in this application. After the third AP receives the first replacement instruction, the third AP sends a replacement notification for the first AP to the configuration device, that is, the configuration device is notified that the third AP is to replace the first AP.

Step 202, if the identifier of the first AP is found from the corresponding relationship between the AP identifier, the CPE identifier and the SSID, replacing the identifier of the first AP with the identifier of the third AP, and obtaining a first SSID corresponding to the identifier of the third AP from the corresponding relationship, where the first SSID is a bridging signal obtained by modifying a bridging signal released externally by the first AP and the first CPE after establishing wireless connection.

In this step, the configuration device may search for the identifier of the first AP from the pre-stored correspondence between the AP identifier, the CPE identifier, and the SSID, determine whether the identifier of the first AP is stored in the correspondence, and if the identifier of the first AP is indeed recorded in the correspondence, the configuration device may replace the identifier of the first AP in the correspondence between the group of the AP identifier where the first AP identifier is located, the CPE identifier, and the SSID with the identifier of the third AP, and search for the first SSID corresponding to the identifier of the third AP from the correspondence. In the step, the identifier of the AP in the group of correspondences where the identifier of the original first AP in the correspondences is located is modified to the identifier of the third AP, and the first SSID corresponding to the identifier of the third AP is obtained, so that if the subsequent configuration device receives the scanning result of the bridge signal in the environment returned by the third AP and includes the first SSID, the configuration device can reconfigure the bridge signal externally released by the third AP according to the first SSID, so as to facilitate the connection between the third AP and the first CPE existing in the environment but in the loss-of-connection state, that is, to accomplish the replacement work of the third AP for the first AP.

In this step, the first SSID represents a bridging signal obtained by modifying a bridging signal released by the first AP and the first CPE after the first AP establishes a wireless connection with the first CPE. This particular process can be expressed as: after the first AP establishes wireless connection with the first CPE, the first AP actively changes the bridge signal released by itself to the first SSID, and after completing the renaming action of the bridge signal, the first AP may send a bridge signal change instruction including the first SSID to the first CPE, so that the first CPE also changes the bridge signal released by itself to the first SSID. Further, after the first AP and the first CPE change their own bridge signals to the first SSID, the first AP may send its own identifier, the identifier of the first CPE, and the first SSID to the configuration device, so that the configuration device stores the corresponding relationship between the group of APs (the identifier of the AP), the group of CPEs (the identifier of the CPE), and the SSID.

In this step, since the bridge signal of the combination where the first AP and the first CPE are located is different from the bridge signals of the combinations of other APs and CPEs in the area where the combination is located in pairs, when the third AP is used to replace the first AP, the first CPE in the short loss of connection state will not find that the bridge signal of the first SSID which is recently connected by itself exists in the environment by searching the bridge signals existing in the environment, so that the first CPE will always be in a loss of connection state. In the process that an AP releasing the first SSID bridging signal may appear again in the first CPE waiting environment in the offline state, the first CPE may periodically or for a long time period release the first SSID bridging signal, which is not limited in this application.

Step 203, sending a first scanning request to the third AP, so that the third AP searches for a bridge signal in the environment, and returns a first scanning result.

In this step, after determining the first SSID corresponding to the identifier of the third AP, the configuration device may send a scanning request, i.e., a first scanning request, to the third AP, so that the third AP searches for a bridge signal existing in the environment, and returns the searched bridge signal to the configuration device.

In this step, if only the combination of the group of APs where the first AP is located and the CPE is located in the area where the first AP is located, after the third AP searches for the bridging signal existing in the environment, only the bridging signal of the first SSID externally released by the first CPE can be searched for; if a combination of other APs and the CPE still exists in the area where the first AP is located, after the third AP searches for the bridging signal existing in the environment, the third AP may search not only the bridging signal of the first SSID externally released by the first CPE, but also the bridging signal released by the other APs and the bridging signal released by the CPE connected to the third AP, where the two bridging signals are the bridging signals with the same name. It is noted that the configuration device may now receive the bridging signal of the first SSID and the same bridging signal (with a strong or weak score) released by the APs and CPEs of the other combinations of APs and CPEs, respectively.

Step 204, if it is determined that the first scanning result includes the first SSID, sending a first configuration request carrying the first SSID to the third AP, so that the third AP establishes a wireless connection with the first CPE after changing an externally released bridging signal to the first SSID.

In this step, after determining, by the configuration device, that the scanning result returned by the third AP includes the bridging signal of the first SSID, the configuration device determines that the environment has the first CPE originally connected to the first AP, so that the configuration device may perform the following processing to notify the third AP of a replacement of the first AP: thus, after the third AP receives the first configuration request, the bridging signal released by the third AP from the outside can be actively changed from the default bridging signal to the bridging signal of the first SSID, and the bridging signal of the first SSID is released to the environment, so that after the first SSID is searched, the first CPE confirms that the bridging signal is consistent with the bridging signal connected before the first CPE loses the connection, and the first CPE in the loss-of-connection state can be wirelessly connected with the third AP releasing the bridging signal of the first SSID, thereby realizing the replacement of the first AP by the third AP.

The above-described embodiments can be explained by the following examples.

For the system architecture shown in fig. 1, it is assumed that the AP1 fails to implement wireless connection between the AP1 and 3 CPEs, namely, the CPE1-1, the CPE1-2 and the CPE1-3, at this time, the AP1 may send a replacement instruction to the AP3 reinstalled at the original AP1, so that the AP3 receiving the replacement instruction may send a replacement notification to the configuration device to notify the configuration device that it needs to be configured based on the information of the AP1 in the subsequent configuration process.

The configuration device receiving the replacement notification searches the identifier of the AP1 from the correspondence between the pre-stored AP identifier, CPE identifier and SSID, and if the configuration device searches the identifier of the AP1 from the identifier, replaces the identifier of the first AP1 with the identifier of the AP3, and searches the bridge signal of the SSID8 from the correspondence according to the identifier of the AP3 (i.e., the identifier of the original AP 1).

The configuring device may then send a scan request to AP3 instructing AP3 to search for bridging signals present in the environment and send the scan results to the configuring device. After receiving the scan request, the AP3 searches for a bridge signal existing in the environment, and the scan result may include: bridge signals periodically released outwards by CPE1-1, CPE1-2 and CPE1-3, such as SSID8, wherein SSID8 is obtained by modifying the bridge signals released outwards by AP1, CPE1-1, CPE1-2 and CPE1-3 respectively after wireless connection is established between AP1 and CPE1-1, CPE1-2 and CPE1-3 respectively; and, the bridging signals released by AP2 located in the same area as AP3, such as SSID18 (strong signal strength), and the bridging signals released by CPEs 2-1, 2-2, 2-3, and 2-4 that establish wireless connection with AP2 are also SSID18 (weak signal strength). Thus, the AP3 may return a total of 3 bridging signals to the configuring device including SSID8 and a strong-weak SSID 18.

Accordingly, the provisioning device may receive the scan result of SSID8 and a strong and weak SSID18, which are 3 bridging signals, and thus determine from the scan result that there is a bridging signal of the SSID 3 identifying the corresponding SSID8, so that the provisioning device may determine that there are CPEs (i.e., CPE1-1, CPE1-2, and CPE1-3) in an offline state and waiting for establishing a wireless connection in the environment, and finally, the provisioning device may send a first provisioning request including the SSID8 to the AP3, so that the AP3 changes the bridging signal released externally to the SSID8, so that, during the AP3 continuously releases externally with the bridging signal of the SSID8, the CPE1-1, the CPE1-2, and the CPE1-3 in the offline state may search for the SSID8 released by the AP3 while searching for the bridging signal in the environment with the bridging signal of the SSID8, and thus, the SSID 1-1, CPE1-2 and CPE1-3 may be reconnected to AP3, thus enabling a wireless connection between the alternative AP and the CPE.

Through the mode, the problem that in the AP replacement process, a constructor needs to climb to the installation position of the CPE to electrify the CPE after power failure can be solved, and the wireless connection between the new AP and the CPE can be realized. The mode can quickly realize the wireless connection between the new AP and the CPE only by sending the action of changing the bridge signal to the new AP on the configuration equipment.

Optionally, a second replacement advertisement for the first CPE sent by a second CPE is received, where the second replacement advertisement is sent by the second CPE after receiving a second replacement instruction sent by the first CPE that establishes a wireless connection with the first AP; if the identifier of the first CPE is found from the corresponding relationship, replacing the identifier of the first CPE with the identifier of the second CPE, and acquiring the first SSID corresponding to the identifier of the second CPE from the corresponding relationship; sending a second scanning request to the second CPE so that the second CPE searches for a bridging signal in the environment and returns a second scanning result; if the second scanning result is determined to include the first SSID, sending a second configuration request carrying the first SSID to the second CPE, so that the second CPE establishes wireless connection with the first AP after changing the externally released bridging signal into the first SSID.

For the system architecture shown in fig. 1, it is assumed that the CPE1-1 fails to implement the wireless connection between the CPE1-1 and the AP1, at this time, the CPE1-1 may send a replacement instruction to the CPE3 reinstalled at the original CPE1-1, and thus, the CPE3 receiving the replacement instruction may send a replacement notification to the configuration device to notify the configuration device that it needs to be configured based on the information of the CPE1-1 in the subsequent configuration process.

The configuration device receiving the replacement notification searches the identifier of the CPE1-1 through the correspondence between the pre-stored AP identifier and the CPE identifier and the SSID, and if the configuration device searches the identifier of the CPE1-1 from the identifier, the configuration device replaces the identifier of the CPE1-1 with the identifier of the CPE3, and searches the bridge signal of the SSID8 from the correspondence according to the identifier of the CPE3 (i.e., the identifier of the original CPE 1-1).

The configuration device may then send a scan request to CPE3 instructing CPE3 to search for bridging signals present in the environment and send the scan results to the configuration device. CPE3, upon receiving the scan request, searches for bridging signals present in the environment, and the scan results may include: the bridging signal released by the AP1 is SSID8, and the bridging signal released by the AP2 located in the same area as the AP1 is SSID 18. Thus, CPE3 may return SSID8 and SSID18, 2 bridging signals to the configured device.

Accordingly, the configuration device may receive SSID8 and SSID18, the scan results of 2 bridging signals, the configuring device thus determines from the scan results that there is a bridging signal identifying the corresponding SSID8 of the CPE3, so that the configuring device can determine that there is an AP1 in the environment that can establish a wireless connection, and finally the configuring device can send a second configuration request to the CPE3 that includes the SSID8, so that the CPE3 changes its own externally released bridging signal to the SSID8, and thus, during the process that the AP3 continuously releases to the outside with the bridging signal SSID8, the CPE1-1, CPE1-2 and CPE1-3 in the offline state can search for the SSID8 released to the outside by the AP3 when searching for the bridging signal in the environment with the bridging signal SSID8, in this manner, CPE1-1, CPE1-2, and CPE1-3 may be reconnected to AP3, thus enabling a wireless connection between the replacement AP and CPE. Thus, CPE3 may establish a wireless connection with AP1 based on SSID 8.

To solve the problems of the background art, an embodiment of the present application provides a connection method for a wireless bridge, which is applied to a first AP, and as shown in fig. 3, the method includes:

step 301, after establishing a wireless connection with a first CPE, changing a bridging signal released externally by the first CPE to a first SSID; the first SSID is different from a second SSID released by any AP in the area where the first AP is located.

Step 302, sending a bridging signal change instruction carrying the first SSID to the first CPE, so that the first CPE changes a bridging signal released by the first CPE to the first SSID.

Step 303, sending the identifier of the first AP, the identifier of the first CPE, and the first SSID to a configuration device, so that the configuration device correspondingly stores the identifier of the first AP, the identifier of the first CPE, and the first SSID in a corresponding relationship between the AP identifier, the CPE identifier, and the SSID.

Step 304, sending a first replacement instruction to a third AP to make the third AP send a first replacement advertisement for the first AP to the configuration device, after the configuration device finds the identifier of the first AP from the corresponding relationship, the identifier of the third AP is substituted for the identifier of the first AP, and the first SSID corresponding to the third AP is obtained from the corresponding relationship, sending a first scanning request to the third AP through the configuration device, searching a bridging signal in the environment by the third AP and returning a first scanning result, after the configuration device determines that the first scanning result includes the first SSID, a first configuration request carrying the first SSID is sent to the third AP, and the third AP establishes wireless connection with the first CPE after changing an externally released bridging signal to the first SSID.

For the system architecture shown in fig. 1, after the AP1 establishes wireless connection with the CPE1-1, the CPE1-2, and the CPE1-3 based on bridging signals set by a factory, the AP1 triggers locking through dialing or software, and changes the bridging signals released by the AP from the outside to SSID8 from bridging signals set by default by the factory; based on the same reason, after the AP2 establishes wireless connection with the CPE2-1, the CPE2-2, the CPE2-3, and the CPE2-4 based on the bridge signals set by the factory, the AP2 changes the bridge signals released by itself to the SSID18 from the bridge signals set by the factory default through dialing or software-triggered locking, wherein the bridge signals released by the AP1 and the AP2 need to be changed to be different, such as the SSID8 and the SSID18 of the present application. After the AP1 changes the bridge signal released by itself to the outside to the SSID8, the AP1 may respectively send SSID change instructions to the CPEs 1-1, 1-2, and 1-3 to change the bridge signal released by itself to the SSID8 from the bridge signal set by default factory, in other words, after the CPE1-1, the CPE1-2, and the CPE1-3 receive the SSID change instruction sent by the AP1, respectively change the bridge signal released by itself to the SSID8 from the bridge signal set by default factory, and after the CPEs change the bridge signal released by themselves to the SSID8, the AP1 may send the identifier of itself, the identifiers of the CPEs 1-1, the identifiers of the CPEs 1-2, and the CPE1-3, and the SSID8 to the configuration device, and the configuration device stores the corresponding relationship of the combination; for the same reason, after the AP2 changes the bridge signal released by itself to the SSID18, by sending SSID change indications to CPE2-1, CPE2-2, CPE2-3 and CPE2-4 respectively, the bridging signal used for releasing the bridging signal itself to the outside is changed to SSID18 from the default factory-set bridging signal, in other words, after receiving the SSID change instruction sent by AP2, CPE2-1, CPE2-2, CPE2-3 and CPE2-4, respectively change the bridge signals released by the external devices from the default factory-set bridge signals to SSID18, after the CPE changes the bridge signal released by itself to the SSID18, the AP1 may send the identifier of the CPE 353535353532, the identifiers of the CPE2-1, the CPE2-2, the CPE2-3, and the CPE2-4, and the SSID18 to the configuration device, and the configuration device stores the corresponding relationship of the combination. Therefore, after the wireless connection is established for the first time for any combination of the AP and the CPE in the same area, the bridge signals released by the AP and the CPE in the combination are changed, so that the bridge signals between any two combinations in the area are different, and when the AP or the CPE of a certain combination in the area is replaced, the AP or the CPE does not need to be manually configured, and the rapid replacement can be realized only by configuring the configuration equipment.

To solve the problems of the background art, an embodiment of the present application provides a connection method for a wireless bridge, which is applied in a third AP, and as shown in fig. 4, the method includes:

step 401, after receiving a first replacement instruction sent by a first AP that establishes a wireless connection with a first CPE, sending a first replacement announcement for the first AP to a configuration device, so that if the configuration device finds an identifier of the first AP from a corresponding relationship between an AP identifier, a CPE identifier, and an SSID, the configuration device replaces the identifier of the first AP with the identifier of a third AP, obtains a first SSID corresponding to the identifier of the third AP from the corresponding relationship, and sends a first scanning request, where the first SSID is a bridging signal obtained by modifying bridging signals released from the first AP and the first CPE respectively after establishing a wireless connection with the first AP and the first CPE.

Step 402, after receiving the first scanning request, searching for a bridging signal in an environment and returning a first scanning result to the configuration device, so that if the configuration device determines that the first scanning result includes the first SSID, the configuration device sends a first configuration request carrying the first SSID to the third AP.

Step 403, receiving the first configuration request, and establishing a wireless connection with the first CPE after changing the externally released bridging signal to the first SSID.

The method for executing the third AP may refer to the method for executing the AP3 in the foregoing example, and is not described in detail.

In some implementations of the present application, after the wireless connection is established with the first CPE after the bridge signal released to the outside is changed to the first SSID, the method further includes: changing the externally released bridging signal from the first SSID to a third SSID; the third SSID is different from a second SSID released by any AP in the area where the third AP is located; sending a bridging signal change instruction carrying the third SSID to the first CPE so that the first CPE changes the externally released bridging signal into the third SSID.

For example, in the foregoing example, after the goal of replacing the AP1 with the AP3 is achieved, the bridging signal between the AP3 and the combination of the CPEs 1-1, 1-2 and 1-3 may be changed again, for example, the AP3 changes the bridging signal released from outside to the SSID28 by means of dialing or software-triggered locking, the SSID28 is different from the bridging signal of the combination of the AP2 released from outside to the SSID18 in the same area as the AP3, then the AP3 sends bridging signal change indications to the CPEs 1-1, 1-2 and 1-3 respectively, so that the CPEs 1-1, 1-2 and 1-3 respectively change the bridging signal released from outside to the SSID28, and the CPE1-3 after the combination is updated CPE correspondence is stored by the configuration device, so that if the replacement event of the AP3 or the replacement event of the CPEs 1-1, 1-2 and 1-3 continues, the replacement can be accomplished by simple operations on the configuration device according to SSID 28.

To solve the problems of the background art, an embodiment of the present application provides a connection method for a wireless bridge, which is applied in a first CPE, and as shown in fig. 5, the method includes:

step 501, after establishing a wireless connection with a first AP, receiving a bridging signal change instruction carrying a first SSID and sent by the first AP, where the bridging signal change instruction is sent by the first AP after changing a bridging signal released externally by the first AP to the first SSID, and the first AP sends an identifier of the first AP, an identifier of a first CPE, and the first SSID to a configuration device, so that the configuration device correspondingly stores the identifier of the first AP, the identifier of the first CPE, and the first SSID in a corresponding relationship between an AP identifier, a CPE identifier, and an SSID.

Step 502, changing the externally released bridging signal to the first SSID, so that a third AP replacing the first AP sends a first replacement advertisement for the first AP to the configuration device after receiving a first replacement instruction sent by the first AP, after the configuration device finds the identifier of the first AP from the corresponding relationship, the identifier of the third AP replaces the identifier of the first AP, the first SSID corresponding to the identifier of the third AP is obtained from the corresponding relationship, a first scanning request is sent, the third AP searches for a bridging signal in an environment and returns a first scanning result to the configuration device, after the configuration device determines that the first scanning result includes the first SSID, a first configuration request carrying the first SSID is sent to the third AP, and the third AP establishes wireless connection with the first CPE after changing an externally released bridging signal to the first SSID.

The execution method of the first CPE may refer to the execution method of the CPE1-1 in the foregoing example, and is not described in detail.

In some embodiments of the present application, a second replacement instruction is sent to a second CPE to cause the second CPE to send a second replacement advertisement for the first CPE to the configuration device, after the configuration device receives the second replacement notification, if the identifier of the first CPE is found from the corresponding relationship, replacing the identifier of the first CPE with the identifier of the second CPE, acquiring the first SSID corresponding to the identifier of the second CPE from the corresponding relationship, sending a second scanning request to the second CPE, searching a bridging signal in the environment by the second CPE and returning a second scanning result, after the configuration device determines that the second scanning result includes the first SSID, a second configuration request carrying the first SSID is sent to the second CPE, and the second CPE changes an externally released bridging signal to the first SSID and establishes wireless connection with the first AP.

The second CPE may refer to the CPE3 in the foregoing example, and is not described in detail.

The application also proposes a semi-automated method for replacing an AP or a CPE, respectively as follows:

for the foregoing example, when the AP3 is used to replace the damaged AP1, after the AP3 is powered on, a worker may log in to a management interface for configuring the AP3, as shown in fig. 6, which is a management interface for configuring the AP3 provided for the implementation of the present application. Referring to fig. 6, the worker instructs the AP3 to search for bridging signals present in the environment by clicking on the "scan" option in the first area to the right of the blank box 1.

By scanning the bridging signals existing in the environment through the AP3, the AP3 sends the first scanning result to the configuration device, and the configuration device displays the first scanning result. As shown in fig. 6, the first scanning results, SSID8 and 2 SSID18, are displayed in the second area.

After the first scanning result is displayed in the second area, the staff member is required to determine that the bridging signal when the AP1 is replaced by the AP3 should be set to the SSID8, and then manually click on the line of "SSID 8", so that the SSID8 appears in the blank box 1 of the first area. After the SSID8 has been displayed in the blank frame 1 of the first area, at this time, the staff clicks the "save configuration" option of the first area, so that the bridging signal that is released by the AP3 to the outside and is default to the factory default is changed to the SSID8, that is, the AP3 releases the bridging signal to the outside with the SSID 8; after the CPE1-1, CPE1-2, and CPE1-3 in the offline state find the bridge signal of the SSID8 in a certain bridge signal search period of the CPE, the CPE1-1, the CPE1-2, and the CPE1-3 in the offline state send a wireless connection establishment request to the AP3 that releases the bridge signal of the SSID8 into the environment, and after the AP3 receives the wireless connection establishment request, wireless bridges between the AP3 and the CPEs 1-1, 1-2, and the CPE1-3 are established.

For the foregoing example, when the CPE3 is used to replace the damaged CPE1-1, after the CPE3 is powered on, a worker may log in to a management interface for configuring the CPE3, as shown in fig. 7, which is a management interface for configuring the CPE3 provided in this embodiment of the present application. Referring to fig. 7, the worker instructs CPE3 to search for bridging signals present in the environment by clicking on the "scan" option in the first area to the right of the blank box 1.
