When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

At present, an access mode of a Mesh device when accessing a Mesh network is a connection mode between the Mesh device (generally, a Mesh device other than a control end device) and a higher-level neighbor node thereof. Referring to fig. 1, an AP #1 is a control end device in a Mesh network, and accesses an external network through a wired access manner, an upper-level neighbor node of an AP #2 is the AP #1, the AP #2 is accessed into the Mesh network through a wireless access manner, an upper-level neighbor node of an AP #3 is the AP #2, and the AP #3 is accessed into the Mesh network through a wired access manner.

In an actual use environment, the access mode shown in fig. 1 is generally determined by a user, and a better access mode cannot be determined by the Mesh device itself. In order to solve the above problem, the present disclosure provides a method for accessing a network, which may determine an access manner of accessing a Mesh network by a Mesh device itself.

The method for accessing the network provided by the present disclosure is first introduced from the first Mesh device side.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for accessing a network according to an exemplary embodiment of the present disclosure, which is described from a first Mesh device side, where the first Mesh device includes, but is not limited to, any router device except a control end device. As shown in fig. 2, the method for accessing the network includes the following steps:

in step 201, it is determined that a target Mesh device is detected through the wired interface of the first Mesh device.

The target Mesh device is a neighbor Mesh device which is in the same networking network as the first Mesh device and supports an optimal superior node as the first Mesh device.

In step 202, it is determined that the access mode of the first Mesh device accessing the Mesh network is a wired access mode, and a Mesh wired connection is established with the target Mesh device through a wired interface of the first Mesh device.

In the above embodiment, the first Mesh device may automatically determine that the access mode accessing the Mesh network is the wired access mode and establish wired connection with the target Mesh device when detecting, through its own wired interface, a neighbor Mesh device that is in the same networking network and supports an optimal superior node as the first Mesh device, that is, the target Mesh device, so as to achieve the purpose of automatically accessing the Mesh network through the wired access mode and optimize the topology structure of the Mesh network.

In some alternative embodiments, referring to fig. 3A, fig. 3A is a flow chart illustrating another method for accessing a network according to the embodiment shown in fig. 2, the method further comprising the steps of:

in step 203, in response to determining that the wired interface of the first Mesh device is in an unlinked state, determining that an access mode of the first Mesh device accessing the Mesh network is a wireless access mode, and accessing the Mesh network through the wireless interface of the first Mesh device.

In the embodiment of the present disclosure, if the first Mesh device determines that no network cable accesses the wired interface of itself, it may be determined that the wired interface is in an unlinked state. Correspondingly, the first Mesh device may determine that an access mode of the first Mesh device to the Mesh network is a wireless access mode, and access the Mesh network through a wireless interface of the first Mesh device.

In the above embodiment, the first Mesh device may automatically determine that the access mode of the first Mesh device to the Mesh network is a wireless access mode when determining that the wired interface of the first Mesh device is in an unlinked state, and access the first Mesh device to the Mesh network through the wireless interface of the first Mesh device. The Mesh network can be automatically accessed in a wireless access mode, and the topological structure of the Mesh network is optimized.

In some alternative embodiments, referring to fig. 3B, fig. 3B is a flow chart illustrating another method for accessing a network according to the embodiment shown in fig. 2, the method further comprising the steps of:

in step 204, in response to determining that the wired interface of the first Mesh device is in the link state but the target Mesh device is not detected, determining that an access manner of the first Mesh device accessing the Mesh network is a wireless access manner, and accessing the Mesh network through the wireless interface of the first Mesh device.

In the embodiment of the present disclosure, if the first Mesh device determines that a network cable accesses any wired interface of itself, it may be determined that the wired interface is in a link state. Further, the first Mesh network determines that the target Mesh device is not detected through the wired interface, and then the first Mesh device may determine that an access mode of accessing the Mesh network is a wireless access mode, and access the Mesh network through the wireless interface of the first Mesh device. The target Mesh device is a neighbor Mesh device which is in the same networking network as the first Mesh device and supports the first Mesh device as an optimal superior node of the first Mesh device in the Mesh network.

In the above embodiment, the first Mesh device may automatically determine that the access mode of the first Mesh device to the Mesh network is a wireless access mode when it is determined that the wired interface of the first Mesh device is in the link state but the target Mesh device is not detected, and access the Mesh network through the wireless interface of the first Mesh device. The Mesh network can be automatically accessed in a wireless access mode, and the topological structure of the Mesh network is optimized.

In some alternative embodiments, referring to fig. 4, fig. 4 is a flowchart illustrating another method for accessing a network according to the embodiment shown in fig. 2, and step 201 may include the following steps:

in step 401, in response to determining that at least one second Mesh device is detected through the wired interface of the first Mesh device, a detection request message is sent to the at least one second Mesh device through the wired interface of the first Mesh device.

In this disclosure, the second Mesh device is a neighbor Mesh device of the first Mesh device, and the probe request packet may be used to request the second Mesh device to determine whether the first Mesh device and the second Mesh device are in the same networking network.

In one possible implementation, the probe request message includes at least one of the following: a first networking identifier of a Mesh network where the first Mesh device is located; the first network hop count is used for indicating the number of Mesh devices which need to pass by when the first Mesh device reaches a control end device, and the control end device is a Mesh device which is communicated with an external network in a Mesh network; the device identifier of the first Mesh device.

The method for determining the first networking identifier by the first Mesh device includes any one of the following:

in the first mode, the first networking identifier is determined based on information broadcast by the control end device.

The Mesh device as the control end device may automatically generate the first networking identifier if it is determined that the Mesh device is configured as the control end device, or determine the first networking identifier based on user configuration. The control end device broadcasts the first networking identifier, so that the first Mesh device determines the first networking identifier based on the information content broadcasted by the control end device.

In the second mode, the first networking identifier is determined by the superior node.

After determining the first networking identifier, the control end device may notify its own child device of the first networking identifier, and then notify its own child device of the control end device, that is, each child device determines the first networking identifier based on information sent by the upper node.

In this disclosure, the first network hop count may be used to indicate the number of Mesh devices that need to pass through from the first Mesh device to the control end device. The control terminal device is a Mesh device which communicates with an external network in a Mesh network. For example, in fig. 1, the first network hop count corresponding to AP #2 is 1, and the first network hop count corresponding to AP #3 is 2.

In the embodiment of the present disclosure, the device identification includes, but is not limited to, a MAC (Media Access Control) Address.

In step 402, a probe response message sent by a third Mesh device is received through a wired interface of the first Mesh device.

The third Mesh device is a neighbor Mesh device in the second Mesh device, which is in the same networking network as the first Mesh device, and the detection response message is used for indicating that the first Mesh device and the third Mesh device are in the same networking network. And if the first Mesh equipment does not receive any detection response message, directly determining that the target Mesh equipment is not detected.

In one possible implementation, the probe response packet includes at least one of the following: a second network hop count used for indicating the number of Mesh devices which need to pass by the third Mesh device to reach a control end device, wherein the control end device is a Mesh device which is communicated with an external network in the Mesh network; the device identifier of the third Mesh device.

In step 403, in response to determining that there is a Mesh device supporting the optimal superior node as the first Mesh device in the third Mesh device, determining that the target Mesh device is detected through the wired interface of the first Mesh device.

In the above embodiment, the first Mesh device may send the detection request packet through the wired interface, and when receiving the detection response packet sent by the third Mesh device through the wired interface, it is determined that the third Mesh device and the first Mesh device are in the same networking network.

In some optional embodiments, referring to fig. 5, fig. 5 is a flowchart of another method for accessing a network according to the embodiment shown in fig. 4, and the step 403 of determining that an optimal upper node of the first Mesh device exists in the third Mesh device may include the following steps:

in step 501, in the third Mesh device, it is determined that one Mesh device is supported as a candidate upper node of the first Mesh device.

In a possible implementation manner, if the number of the probe response packets received by the first Mesh device is one, it may be determined that the number of the third Mesh device is one, and meanwhile, the second network hop count in the received probe response packet is an effective hop count, so that the first Mesh device may determine that the third Mesh device supports the candidate upper node serving as the first Mesh device. The second network hop count is used for indicating the number of Mesh devices which need to pass by when the third Mesh device reaches the control end device, and the control end device is a Mesh device which communicates with an external network in the Mesh network.

In this disclosure, the second network hop count being an effective hop count may refer to that the second network hop count is an integer value greater than or equal to 0, where the second network hop count is equal to 0, which indicates that the third Mesh device is a control end device, and the second network hop count is greater than 0, which is used to indicate the number of Mesh devices through which the third Mesh device reaches the control end device. Or, the second network hop count being the valid hop count may indicate that the second network hop count does not belong to the invalid hop count, for example, it is predetermined that the invalid hop count is a negative value or a designated form, the designated form may be any form different from a non-negative integer value, and the designated form is assumed to be 0XFF, and if the second network hop count is not a negative value or 0XFF, it indicates that the second network hop count is the valid hop count.

In another possible implementation manner, the number of the probe response packets received by the first Mesh device is multiple, and the second network hops in the probe response packets are all valid hops, so that the first Mesh device may determine that one of the third Mesh devices with the smallest second network hop count supports the candidate upper node serving as the first Mesh device. In another possible implementation manner, the number of the probe response packets received by the first Mesh device is multiple, and the second network hops are both valid hops, and in addition, the number of the third Mesh devices with the smallest second network hops is also multiple, that is, the second network hops corresponding to two or more third Mesh devices are the same and the smallest, so that the first Mesh device may determine, in the third Mesh devices with the smallest second network hops, that one third Mesh device whose device identifier meets the first specified condition supports the candidate upper node as the first Mesh device. Optionally, the device identifier comprises a media access control, MAC, address, and the first specified condition comprises: the MAC address is minimum, or the MAC address is maximum.

In step 502, in response to determining that the third Mesh device as the candidate upper node is the optimal upper node of the first Mesh device, it is determined that the optimal upper node of the first Mesh device exists in the third Mesh device.

In a possible implementation manner, the first Mesh device does not currently access the Mesh network, and then the first Mesh device may directly determine that the third Mesh device serving as the candidate superior node is the optimal superior node of the first Mesh device.

In another possible implementation manner, the first Mesh device has currently accessed to the Mesh network, and the access manner is a wired access manner or a wireless access manner, so that the first Mesh device may determine that the third Mesh device serving as the candidate upper node is the optimal upper node of the first Mesh device when determining that the first network hop count is greater than the second network hop count.

The first network hop count is used for indicating the number of Mesh devices which need to pass by when the first Mesh device reaches a control end device, the second network hop count is used for indicating the number of Mesh devices which are used as the candidate Mesh devices and are spaced between the third Mesh device and the control end device, and the control end device is a Mesh device which is communicated with an external network in a Mesh network.

For example, if the first network hop count is 2 and the second network hop count is 1, the first Mesh device may determine that the candidate Mesh device is the optimal upper node of the first Mesh device.

In another possible implementation manner, a first Mesh device has currently accessed to the Mesh network, the access manner is a wired access manner or a wireless access manner, and the first network hop count is the same as the second network hop count, so that the first Mesh device may determine that the third Mesh device serving as the candidate superior node is the optimal superior node of the first Mesh device when the device identifier of the first Mesh device and the device identifier of the candidate Mesh device satisfy a second specified condition.

Wherein the device identification comprises a MAC address, and the second specified condition comprises any one of: the MAC address of the first Mesh device is smaller than the MAC addresses of the candidate Mesh devices; the MAC address of the first Mesh device is larger than the MAC addresses of the candidate Mesh devices.

For example, the first network hop count is 2, the second specified condition includes that the MAC address of the first Mesh device is smaller than the MAC address of the candidate Mesh device, and the first Mesh device may determine that the third Mesh device serving as the candidate upper node is the optimal upper node of the first Mesh device, assuming that the MAC address of the first Mesh device is smaller than the MAC address of the candidate Mesh device.

In the above embodiment, the first Mesh device may determine whether the third Mesh device serving as the candidate upper node is the optimal upper node of the first Mesh device according to the access mode currently accessing the Mesh network, the first network hop count, and the second network hop count, so as to determine the optimal access mode in the subsequent process, and the availability is high.

In some optional embodiments, referring to fig. 6, fig. 6 is a flowchart illustrating another method for accessing a network according to the embodiment shown in fig. 2, where the method may further include the following steps:

in step 205, in response to determining that the access state of the first Mesh device accessing the Mesh network changes, it is determined that the access mode of the first Mesh device accessing the Mesh network is switched.

Wherein the access state includes, but is not limited to, any of: an unaccessed state, a wired access state, and a wireless access state. In an embodiment of the present disclosure, a change procedure of the first Mesh device between different access states is provided, for example, as shown in fig. 7.

TABLE 1

The first network hop count is used for indicating the number of Mesh devices which need to pass by when the first Mesh device reaches a control end device, and the control end device is a Mesh device which communicates with an external network in a Mesh network.

It should be noted that the invalid hop count may refer to a network hop count being a negative value or a designated form, and the designated form may be any form different from a non-negative integer value, assuming 0XFF, if the first network hop count is updated to the invalid hop count, the first Mesh device may update the first network hop count to any negative value, for example, -1, -0.99, etc., thereby indicating that the first network hop count is the invalid hop count. Alternatively, the first Mesh device may update the first network hop count to a specified form, such as 0XFF, indicating that the first network hop count is an invalid hop count.

And under the condition that the first Mesh device starts a wireless interface of the first Mesh device, the first Mesh device tries to access the Mesh network in a wireless access mode.

In this embodiment of the present disclosure, the updating the first network hop count may include: the target network hop count is first determined. The target network hop count is used for indicating the number of Mesh devices which need to pass by when the neighbor Mesh devices serving as the superior nodes of the first Mesh device reach the control terminal device. Further, the first network hop count is updated to the target network hop count plus one.

If the first Mesh device is in a wired connection mode with a neighbor Mesh device serving as a superior node of the first Mesh device, the neighbor Mesh device serving as the superior node of the first Mesh device is the target Mesh device, the target network hop count is the number of Mesh devices which the target Mesh device needs to pass through to reach the control end device, and the first Mesh device can determine the target network hop count through a detection response message sent by the target Mesh device.

If the first Mesh device is in a wireless connection mode with the neighbor Mesh device as the superior node, the first Mesh device can receive the target network hop count sent by the neighbor Mesh device as the superior node through a wireless interface.

In the above embodiment, it may be determined that the access mode of the first Mesh device is switched when the access state of the first Mesh device accessing the Mesh network is changed. And after the neighbor Mesh device of the superior node as the first Mesh device is changed, the first network hop count of the first Mesh device may be updated. According to the method and the device, the first Mesh equipment can be automatically switched between the wired access mode and the wireless access mode, the flexibility of the access mode is improved, meanwhile, the topological structure of the Mesh network is optimized, and the usability is high.

As shown in fig. 8, the method for accessing the network includes the following steps:

The first Mesh device is a neighbor Mesh device of the second Mesh device, and the detection request packet is used for requesting the second Mesh device to determine whether the first Mesh device and the second Mesh device are in the same networking network. And after detecting the second Mesh equipment through the wired interface of the first Mesh equipment, the first Mesh equipment sends a detection request message to the second Mesh equipment.

In this embodiment of the present disclosure, the second Mesh device may determine the second networking identifier of the Mesh network where the second Mesh device is located, and the determination manner is similar to the process of determining the first networking identifier by the first Mesh device, which is not described herein again.

If the second networking identifier is the same as the first networking identifier, the second Mesh device may determine that the first Mesh device and the second Mesh device are in the same networking network. If the second networking identifier is different from the first networking identifier, the second Mesh device may determine that the first Mesh device and the second Mesh device are in different networking networks.

Further, when determining that the first Mesh device and the second Mesh device are in the same networking network, the second Mesh device sends a detection response message to the first Mesh network through a wired interface of the second Mesh device, where the detection response message is used to indicate that the first Mesh device and the second Mesh device are in the same networking network. And if the first Mesh equipment and the second Mesh equipment are determined to be in different networking networks, determining not to send a detection response message to the first Mesh equipment.

In the above embodiment, the second Mesh device may determine whether the second Mesh device and the first Mesh device are in the same networking network after receiving the detection request message sent by the first Mesh device through its wired interface, and send the detection response message to the first Mesh network through the wired interface of the second Mesh device after determining that the first Mesh device and the second Mesh device are in the same networking network, so that the first Mesh device further determines the target Mesh device in the Mesh devices sending the detection response message subsequently, thereby optimizing the topology structure of the Mesh network and having high availability.
