For example, in fig. 1, the image pickup device 11 receives the distribution network information sent by the access point device 2 first, and then according to the distribution network policy of the prior art, the image pickup device 11 accesses the access point device 2, thereby causing a distribution network error.

The wireless network access method of the present application will be described in detail with reference to three specific embodiments.

In a first aspect:

the embodiment provided in the first aspect is mainly applied to a user equipment, where the user equipment may be a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), and the like, and the application is not limited in this respect.

Referring to fig. 2, fig. 2 is a flowchart illustrating a wireless network access method according to an embodiment of the present application, which specifically includes:

step S21: the user equipment acquires at least one piece of first identification information, wherein the first identification information is used for identifying the camera equipment.

In one implementation scenario, in order to uniquely identify the image capturing device, the first identification information may be at least one of a device serial number and a Media Access Control (MAC) Address of the image capturing device.

In one implementation scenario, in order to quickly acquire the first identification information of the image capturing apparatus, the user equipment may obtain the first identification information by scanning an identification code on at least one image capturing apparatus.

Similarly, the configuration of the access point device 2 may be implemented according to the above steps, and this embodiment is not illustrated here.

In this embodiment, the distribution network instruction is used to instruct the access point device to broadcast distribution network information including the first identification information, so that the camera device receiving the distribution network information accesses to the wireless network where the access point device is located when determining that the identification information of the camera device matches the first identification information. That is to say, after receiving a distribution network instruction sent by the user equipment, the access point device broadcasts distribution network information including the first identification information, so that the camera device receiving the distribution network information is accessed to the wireless network where the access point device is located when determining that the identification information of the camera device matches the first identification information. For example, please refer to fig. 1 in combination, the user equipment sends a distribution network instruction to the access point equipment 1, so that the access point equipment 1 broadcasts distribution network information including first identification information of the image pickup equipment 11 to the image pickup equipment 1N, so that the image pickup equipment 11 to the image pickup equipment 1N and the nearby image pickup equipment 21 to the image pickup equipment 2N match their own identification information with the first identification information after receiving the distribution network information, and since the own identification information of the image pickup equipment 21 to the image pickup equipment 2N is not matched with the first identification information in the distribution network information, the image pickup equipment 21 to the image pickup equipment 2N will not access to the wireless network where the access point equipment 1 is located after receiving the distribution network information.

According to the scheme, the user equipment acquires first identification information for identifying the camera equipment, the first identification information is packaged into a distribution network instruction, the distribution network instruction is sent to the corresponding access point equipment, the corresponding access point equipment broadcasts the distribution network information comprising the first identification information based on the distribution network instruction, so that the camera equipment receiving the distribution network information is accessed to a wireless network where the access point equipment is located when the camera equipment determines that the identification information of the camera equipment is matched with the first identification information, networking of the corresponding access point equipment and the specified camera equipment can be realized, directional connection between the access point equipment and the camera equipment is ensured, particularly, under the condition that a plurality of sets of combinations of the access point equipment and the camera equipment exist, the user equipment sends the identification information comprising the camera equipment in the same group of the access point equipment to the access point equipment, and the camera equipment in the same group can be ensured to be networked with the access point equipment, when other combinations exist around the access point equipment, the camera equipment in the other combinations is prevented from being mistakenly accessed to the access point equipment, or the camera equipment in the group is mistakenly accessed to the access point equipment in other groups, so that the directional connection of the access point equipment and the camera equipment can be realized under the condition that a plurality of sets of combinations of the access point equipment and the camera equipment exist, and the accuracy of a distribution network is improved.

In one embodiment, when the user equipment pair is configured, the following situations may also occur: as in the configuration of the access point device 1 in fig. 1, the user equipment misconnects with the access point device 2; or, when configuring, the other user equipment misconnects the access point device 1 in the configuration of the user equipment in fig. 1; or, the user equipment does not mistakenly connect to the access point equipment, but sends the identification information of the other group to the access point equipment, which all cause the access point equipment to mistakenly broadcast the first identification information of the image pickup equipment of the other group, and further cause the image pickup equipment of the other group to access to the access point equipment of the group, thereby causing a network distribution error. In order to avoid the above situation, further avoid that the user equipment accesses the wrong access point device during configuration, or that other user equipment erroneously accesses the access point device of the group when performing similar configuration nearby, please refer to fig. 3, which may further include the following steps:

step S31: second identification information for identifying the access point device is acquired.

In one implementation scenario, the second identification information may be at least one of a device serial number and a MAC address of the image capturing apparatus in order to uniquely identify the access point device.

In one implementation scenario, in order to quickly acquire the second identification information of the access point device, the user equipment may scan the identification code on the access point device to obtain the second identification information. In another implementation scenario, the second identification information of the access point device may also be imported into the user equipment by a direct offline import method. In yet another implementation scenario, the access point device may further connect with the user equipment, so that the access point device sends the local second identification information to the user equipment. The present embodiment is not described in detail herein.

Referring to fig. 1 in combination, the user equipment may scan the access point device 1 or the access point device 2 to obtain the second identification information of the access point device 1 or the access point device 2.

In this embodiment, the step S22 may specifically include:

step S32: and packaging the first identification information and the second identification information into a distribution network instruction.

In one implementation scenario, the ue and the ap device implement wireless connection through IEEE802.11 protocol, and the ue packages the first identification information into a probe request frame.

Referring to fig. 1, when configuring the access point device 1 and the image capturing device 11 to the image capturing device 1N, the user device may package the second identification information of the access point device 1 and the first identification information of the image capturing device 11 to the image capturing device 1N, which are obtained by scanning, into the distribution network instruction. Similarly, the configuration of the access point device 2 may be implemented according to the above steps, and this embodiment is not illustrated here.

In this embodiment, the distribution network instruction is specifically configured to instruct the access point device that receives the distribution network instruction to broadcast the distribution network information that includes the first identification information when determining that the identification information of the access point device matches the second identification information. Specifically, reference may be made to the steps in the above embodiments, and the embodiments are not illustrated herein.

By means of the scheme, the situation that the user equipment is accessed with wrong access point equipment during configuration or other user equipment mistakenly accesses the access point equipment of the group when similar configuration is carried out nearby is effectively avoided, so that the camera equipment of other groups mistakenly connects the access point equipment of the group, or the camera equipment of the group mistakenly connects the access point equipment of other groups to generate a distribution network error, and the accuracy of a distribution network is further improved.

Wherein in another embodiment, in order to make the user device further confirm that the access point device has received the distribution network instruction transmitted by the access point device. Referring to fig. 4, the wireless network access method according to the first aspect of the present application may further be implemented by:

step S41: the user equipment acquires at least one piece of first identification information, wherein the first identification information is used for identifying the camera equipment.

In an implementation scenario, the second identification information of the access point device may also be obtained together. In order to uniquely identify the Access point device, the second identification information may be at least one of a device serial number, a MAC (Media Access control address) address of the Access point device.

Step S42: and packaging the first identification information into a distribution network instruction.

In an implementation scenario, the obtained second identification information of the access point device and the first flag information may also be packaged into the distribution network instruction.

Step S43: and sending the distribution network instruction to the access point equipment.

In an implementation scenario, step S43 may specifically include: and sending the distribution network instruction to the access point equipment through the wireless network where the access point equipment is located.

And the user equipment sends the distribution network instruction to the access point equipment through the wireless network where the access point equipment is located.

Step S44: and judging whether response messages of the access point equipment are received within preset time. If not, step S45 is executed.

The ue determines whether a response message of the ap device is received within a preset time, which may be set to 5 seconds, 6 seconds, 7 seconds, or the like in an implementation scenario. In one implementation scenario, the ue and the ap implement wireless connection through IEEE802.11 protocol, and the ap sends a probe response frame to respond to the ue.

In an implementation scenario, the distribution network instruction contains second identification information of the access point device, after the access point device receives the distribution network instruction, the second identification information is firstly compared with the local identification information, and if the second identification information is consistent with the local identification information, a response message is sent, so that the situation that the user device is mistakenly connected with the access point device of other groups or other user devices nearby and simultaneously performing distribution network operation are mistakenly connected with the access point device of the group is avoided, and further subsequent distribution network errors are caused.

The above steps can be specifically implemented by referring to the steps in the above embodiments, and this embodiment is not illustrated one by one.

Step S45: returning to step S43 to re-execute the distribution network instruction sent to the access point device.

When the response message of the access point equipment is not received within the preset time, the operation of sending the distribution network instruction to the access point equipment is executed again, so that the situation that the distribution network instruction is not successfully received by the access point equipment possibly caused by network transmission jitter or congestion is avoided. Alternatively, when a response message of the ap device is still not received after a preset threshold is exceeded, for example, 1 minute, 2 minutes, etc., a prompt message may be output to remind the user and give related suggestions, for example: checking whether the network connection is normal, or checking whether the user equipment is mistakenly connected with other groups of access point equipment, and the like.

In an implementation scenario, when the determination result of "determining whether the access point device receives the response message within the preset time" in step S44 is yes, "the following step S46 may be further performed.

Step S46: and ending the flow, namely no longer sending the distribution network instruction to the access point equipment.

After receiving the response message sent by the access point device, the access point device is indicated to have successfully received the distribution network instruction sent by the user device, so that the user device does not need to send the distribution network instruction to the access point device. In one implementation scenario, the user device may output a prompt message to prompt the user that the distribution network instruction is successfully sent.

According to the scheme, when the response message of the access point equipment is not received within the preset time, the distribution network instruction can be sent to the access point equipment again, the access point equipment is further ensured to normally receive the distribution network instruction, and therefore the success rate of distribution network is further ensured.

In a second aspect:

the embodiment provided in the first aspect is mainly applied to an access point device, where the access point device may be a network hard disk video recording device, and specifically may be an NVR integrated with an AP function, and the application is not limited in this respect.

Referring to fig. 5, fig. 5 is a flowchart illustrating a wireless network access method according to an embodiment of the present application. Specifically, the method may include:

step S51: the access point device receives a distribution network instruction sent by the user device, wherein the distribution network instruction comprises at least one piece of first identification information used for identifying the camera device.

In one implementation scenario, the first identification information may include at least one of a device serial number and a MAC address in order to uniquely identify the image capturing device.

In an implementation scenario, the ue and the ap device implement wireless connection through an IEEE802.11 protocol, and the ue packages the first identification information into a probe request frame and sends the probe request frame to the ap device, so that the ap device receives the probe request frame sent by the ue. Specifically, step S51 may include: and receiving a distribution network instruction sent by the user equipment through a wireless network where the access point equipment is located.

Step S52: and generating and broadcasting distribution network information containing the first identification information.

And packaging the first identification information into distribution network information, and broadcasting the distribution network information so that nearby camera equipment receives the distribution network information.

In one implementation scenario, in order to enable the image capturing apparatus to access the access point apparatus based on the received distribution network information, the distribution network information further includes a Service Set Identifier (SSID) and a corresponding password of the access point apparatus.

In an implementation scenario, in order to enable the access point device to periodically broadcast the distribution network Information, so as to reduce the probability that the image capturing device misses the distribution network Information due to network transmission jitter or congestion, the distribution network Information including the first identification Information may be configured in a preset field of a beacon frame (beacon frame), for example, in a private IE (Information Element), and broadcast the beacon frame, where the private IE may be a carrier specific IE (client/provider customized IE) in the beacon frame, and the beacon frame is the prior art in the art, which is not described herein any more.

Step S53: and receiving a connection request sent by the camera equipment when the camera equipment determines that the self identification information is matched with the first identification information.

When the camera device determines that the identification information of the camera device matches the first identification information, it indicates that the access point device sending the distribution network information is the access point device to which the camera device needs to be directionally connected, and at this time, the camera device can initiate a connection request to the access point device.

Referring to fig. 1, the image capturing apparatus 11 to the image capturing apparatus 1N, and the image capturing apparatus 21 to the image capturing apparatus 2N receive the distribution network information sent by the access point apparatus 1, and the distribution network information includes the first identification information of the image capturing apparatuses in the group of the access point apparatus 1, that is, the first identification information of the image capturing apparatus 11 to the image capturing apparatus 1N. At this time, the imaging apparatuses 11 to 1N and 21 to 2N match the identification information of the own devices with the first identification information, so that the imaging apparatuses 11 to 1N find that their own identification information matches with the first identification information, and the imaging apparatuses 21 to 2N find that their own identification information does not match with the first identification information, and then the imaging apparatuses 11 to 1N transmit a connection request to the access point apparatus 1, and the imaging apparatuses 21 to 2N do not transmit a connection request. Similarly, similar steps may be adopted to implement when configuring the access point device 2, and this embodiment is not illustrated here.

Step S54: and responding to the connection request, and establishing connection with the camera equipment so as to enable the camera equipment to be accessed into a wireless network where the access point equipment is located.

The access point device responds to the connection request of the camera device, so that connection between the camera device and the access point device is established, and the camera device is connected to a wireless network where the access point device is located.

Referring to fig. 1, after the image pickup apparatus 11 to the image pickup apparatus 1N send connection requests to the access point apparatus 1, the access point apparatus 1 responds to the connection requests, so as to establish connections with the image pickup apparatus 11 to the image pickup apparatus 1N, and further enable the image pickup apparatus 11 to the image pickup apparatus 1N to access a wireless network in which the access point apparatus 1 is located.

According to the scheme, the access point equipment broadcasts the distribution network information containing the first identification information for identifying the camera equipment, so that the camera equipment is connected with the access point equipment when the identification information of the camera equipment is determined to be matched with the first identification information, networking of the corresponding access point equipment and the appointed camera equipment can be realized, directional connection of the access point equipment and the camera equipment is ensured, particularly, under the condition that multiple sets of combinations of the access point equipment and the camera equipment exist, networking of the camera equipment in the same group with the access point equipment is ensured, directional connection of the access point equipment and the camera equipment is realized, and the accuracy of a distribution network is improved.

In one embodiment, when the user equipment pair is configured, the following situations may also occur: as in the configuration of the access point device 1 in fig. 1, the user equipment is misconnected to the access point device 2; or, when configuring, the other user equipment misconnects the access point device 1 in the configuration of the user equipment in fig. 1; or, the user equipment does not connect the access point device by mistake, but sends the identification information of the other group to the access point device, which all may cause the access point device to broadcast the first identification information of the image pickup devices of the other group by mistake, and further cause the image pickup devices of the other group to access the access point device of the group, thereby causing a distribution network error. In order to avoid the above situation, when the user equipment is configured, the user equipment accesses an access point device with an error, or when other user equipment performs similar configuration nearby, the user equipment misconnects the access point device of the group, and the distribution network instruction may further include second identification information for identifying the access point device, specifically, please refer to fig. 6, before the step S52, the method may further include the following steps:

step S61: and judging whether the self identification information is matched with the second identification information in the distribution network instruction, if so, executing the step S62.

In one implementation scenario, the second identification information may be at least one of a device serial number and a MAC address of the image capturing apparatus, in order to uniquely identify the access point apparatus.

If the second identification information in the distribution network instruction is matched with the identification information of the distribution network instruction, the distribution network instruction is sent without errors, and if not, the distribution network instruction is sent with errors.

Step S62: and generating and broadcasting the distribution network information containing the first identification information.

And if the distribution network instruction is sent without errors, the access point equipment generates and broadcasts distribution network information containing the first identification information.

In one implementation scenario, in order to enable the access point device to periodically broadcast the distribution network Information to reduce the probability that the image capturing device misses the distribution network Information due to network transmission jitter or congestion, the distribution network Information including the first identification Information may be configured in a preset field of a beacon frame (beacon frame), for example, the distribution network Information is configured in a private IE (Information Element) in the beacon frame, and the beacon frame is broadcast. The private IE may be a vendor specific IE (client/vendor customized IE) in a beacon frame, where the beacon frame is a prior art in the field, and this embodiment is not described in detail herein any more

In one implementation scenario, if the determination result of the step S61 is "no", the following step S63 may be further performed.

Step S63: and generating and broadcasting the distribution network information containing the first identification information is not performed.

In an implementation scenario, when step S63 is executed, a prompt message may be further sent to the user equipment to remind the user equipment of a distribution network instruction transmission error.

By means of the scheme, the access point equipment of the group is effectively prevented from being accessed by the user equipment in configuration, or other user equipment is mistakenly connected with the access point equipment of the group when similar configuration is carried out nearby, so that the camera equipment of other groups is mistakenly connected with the access point equipment of the group, or the camera equipment of the group is mistakenly connected with the access point equipment of other groups, and a distribution network error is generated, and the accuracy of a distribution network is further improved.

In another embodiment, the user equipment further confirms that the access point equipment has accepted the distribution network command sent by the access point equipment. After the step 52, sending a response message to the user equipment may be further performed. Reference may be made to the embodiments in the first aspect, and details are not repeated herein.
