It should also be noted that, communication requirement needed for establishing uplink connection, such as matches suitable agreement, generation conforms to The technological means for asking message of format etc. known to those skilled in the art, this is not repeated here.

In order to better understand the above technical scheme, being described in detail With reference to embodiment.

Shown in Figure 2, the embodiment of the present invention provides a kind of networking method of wireless network comprising:

S1: an AP being arranged in multiple AP (Wireless Access Point) is main AP, other AP are to build from AP It is vertical to be connected from AP to the first uplink of the connection of the cable network of main AP and the supreme layer network device of main AP.

Ad-hoc network structure of the invention is simpler, conveniently, be easy to Inspection and maintenance, while cost is relatively low.Establish AP's Host-guest architecture, main AP is for establishing the connection of the first uplink and sending network packet from AP to each.It is set for two kinds relative to setting Standby AC and AP, and AC is set and controls each AP, setting AP receives the control of AC, and network structure of the invention only relates to AP, together When by the corresponding function that is provided with to AP, it is more convenient, simple.Meanwhile each AP is used as access point, is breaking down When, it is the node that can determine that existing failure according to its wireless network fault coverage, it is very easy to be checked and safeguarded.Together When, due to merely relating to AP, it is no longer necessary to which AC, cost are cheaper.

As a preferred embodiment, main AP is established with from when the network connection of AP, and main AP is to the connection permission from AP It is verified.

When establishing main AP with connecting from AP, AP in other networks may crosstalk, at this time if main AP and generating crosstalk AP be connected to the network and interacted, may cause network and various problems occur, such as connect that unstable, network connection system is disorderly Disorderly, establish connection error etc. to.

Further, main AP receives authentication information and verification from AP, and network connection is established if verifying successfully, is otherwise returned Return failure information.

By the way that authentication information is arranged in the connection request from AP, main AP can receive the authentication information and verify, thus Whether the AP in identification network connection is that needs are attached rather than crosstalk/incorrect link.And then reduces and connect It connects unstable, network connection system disorder, establish a possibility that the problems such as connection error.

S2: configuration synchronization request is sent from AP to main AP, after main AP receives the configuration synchronization request, to accordingly from AP Send network configuration.

Network configuration is obtained from AP by interacting with main AP, so that network is more stable.Upon establishment of a connection, it is received from AP The network configuration of main AP, since main AP needs to issue network packet to other from AP, relative to from AP used it is more based on Resource is calculated, it, may in management to network packet is issued while sending network configuration from AP if main AP inadequate resource itself It will appear, due to the Caton of inadequate resource, or even the case where crash.Therefore, configuration synchronization request actively is issued to main AP from AP, Main AP after receiving the request, the network configuration of itself can be just sent to the slave AP for issuing configuration synchronization request, saves main AP management The resource needed from AP, can save the software and hardware resources of main AP.

It should be noted that the first uplink connection that the network configuration of this paper can be main AP was used using wireless mode Network configuration, after main AP or its connection are broken down, the network configuration foundation that connect from AP according to first uplink with it is upper Second wireless uplink of layer network device connects, to work on；Network configuration can also be the wireless connection setting of main AP, And the network settings of wireless network access point such as are provided to the mobile phone of user, after main AP from the wired connection of AP with interrupting, from AP can establish the second wireless uplink connecting with main AP by the setting and connect in the wireless connection setting for knowing main AP, To guarantee main AP and will not be interrupted from the connection between AP；In addition, network configuration can also include the generic configuration number from AP According to for after being connect from AP with main AP, the step of automatically configuring from AP, save artificial configuration.It is preferred that the generic configuration data It is identical as main AP, when user is moved to other WIFI from AP from the WIFI range of main AP, wish network settings with before Equally, it is preferred, therefore, that configuration WIFI is arranged according to main AP connection from AP and is supplied to user, so that user is crossing over main AP When with from AP range boundary, can seamless switching network, better user experience is provided.

S3: when from the cable network disconnecting of AP and main AP, second is established wirelessly from AP using the network configuration Uplink connection.

After establishing ad-hoc network structure of the invention, after main AP relevant connection is interrupted, it can be backed up from AP according to it Network configuration, voluntarily establish the second wireless uplink connection, guarantee from can not from main AP obtain be connected to the network when, can Uplink connection is independently established according to network configuration, and then is worked normally.And the relevant connection of main AP includes: main AP with from AP's The connection of the uplink of connection and main AP is connected for these failures from AP by the second wireless uplink, being capable of autonomous instauration net Network enables and continues WIFI, more stable, safety from AP in network structure of the invention.

As an optional embodiment, network configuration includes the radio network configuration of main AP, when from AP's and main AP When cable network disconnecting, the second wireless uplink is established with main AP from AP and is connect.

When main AP works, can peripherad wireless device wireless access point is provided, when main AP with from the cable network of AP After disconnecting, can be used as wireless device from AP, access main AP again, establish the second wireless uplink connection, thus guarantee from AP can be connected in the case where cable network disconnecting by the second wireless uplink, continue to keep the connection with network, into And it works on.

Further, radio network configuration includes multiple network configurations for being wirelessly connected point, described to select network matter from AP Amount is preferable to be wirelessly connected point connection；It is periodically detected the network quality that second wireless uplink connects from AP, if the net Network is second-rate, then switches to other and be wirelessly connected point.

Need to illustrate is all that network quality described herein can be the rate that data packet is transmitted in network connection, Can be switch rate, power etc. the index of network, if can in terms of one or more reaction network performance.

For example, AP offer is wirelessly included in a little, generally there is two kinds of 2.4G Hz and 5GHz.The nothing of main AP is accessed from AP When line connects, 2.4G or 5G can choose, it is however generally that, 2.4G network can keep more preferable network Quality, 5G network can keep preferable network quality in closer distance.In addition, there are also crosstalk etc. factors to influence each connect The network quality of access point, therefore, in order to guarantee from AP provide preferably network connection, when selecting access point, it is preferable to use Network quality is preferably wirelessly connected a little.Meanwhile periodically carrying out detecting current network quality, after its is poor, switch to Other are wirelessly connected point.

As another optional embodiment, network configuration includes that the wireless network of main AP and upper layer network equipment is matched It sets, the radio network configuration includes multiple network configurations for being wirelessly connected point, in connecting from AP with the cable network of main AP When disconnected, described be preferably wirelessly connected from AP selection network quality a little establishes the connection of the second wireless uplink, second wireless uplink Connection can be between AP and main AP, be also possible to from AP and upper layer network equipment room；Described is periodically detected from AP The network quality of two wireless uplinks connection switches to other nothings if the network quality of second wireless uplink connection is poor Line connection point.

From AP after it can not connect or must be connected to the network from cable network, main AP can be connected also and can connect main AP Upper layer network equipment.Meanwhile when being selected from AP, it is attached according to network quality for judgment criteria, in addition to protecting It demonstrate,proves outside better network working condition, additionally it is possible to prevent failure to the influence from AP, such as main AP failure, main AP and upper layer network is set Standby connecting fault is can establish with the connection of upper layer network equipment from AP to avoid these possible failure generation area. In addition, of the invention be not directly connected upper layer network equipment from AP, the only situation poor in failure or network quality, just into Row connection is capable of the load of biggish reduction upper layer network equipment, forms more flexible connection type.

It should be noted that the radio network configuration of the upper layer network equipment of main AP, can actively inquire upper layer by main AP The network equipment obtains, and is also possible to artificially preset network configuration and is stored in main AP, as long as by the nothing of upper layer network equipment Line network configuration is finally transferred to from AP, for from AP use.

As a preferred embodiment, after establishing the connection of the second wireless uplink from AP, wired network described in real-time detection Whether network connection restores, if cable network connection restores, switches to cable network from second wireless uplink connection Connection.

Wired connection has better table relative to wireless connection, in tunnel dielectric material, anti-crosstalk, secure data area Existing, therefore, after establishing the connection of the second wireless uplink, the connection of examinations cable network restores the present invention in wired connection In the case of, restore wired connection, promotes network quality and user experience.

Meanwhile if all AP are by being wirelessly attached, wireless quantity is excessive in the space, be easy to cause string It disturbs, while wireless connection is unstable compared to wired connection, be easy to cause connection to disconnect, and reduce user experience.It is therefore preferable that The connection for using part is wired connection: if network connection using main AP and from AP is as wired connection, the number of wireless connection Amount will be greatly reduced, so that the network quality from AP is also relatively high, and then have preferable user experience.Due to wired connection phase Compared be wirelessly connected on rate, stability, on joint efficiency it is more high-quality, it is preferred that when the wireless uplink connection of foundation After AP discovery and wired network connection recovery of the main AP of its subordinate, restoring extremely should be from the cable network company of AP and main AP It connects, does not use the wireless uplink connection of itself.

For example, as shown in figure 3, on main AP operation have Server program, from AP operation have Client program and Check program.It carries out quickly networking by following steps.

A1, bundle AP are connected by cable and main AP, and the Client program of sub- AP can be from the main AP request of trend Network configuration information, network configuration information are configured including at least WIFI；

A2, main AP Server program the authentication is passed that backward sub- equipment issues network configuration information；

A3, sub- AP disconnect cable connection, the Check Programmable detection of sub- AP to network interruption；

A4, sub- AP actively initiate to be wirelessly connected using the WIFI configuration saved.After successful connection, sub- AP completes distribution.

As an optional embodiment, after radio network configuration change, if the main AP exists with from AP Updated radio network configuration is sent to from AP by wired connection or the connection of the second wireless uplink, the main AP.

If after change occurs in network configuration, not informed from AP due to the influence of artificial or network failure etc. factor, Greatly connection failure so is likely to occur when, when being attached according to old network configuration, having from AP, and then can not be just Often work.Therefore, after the radio network configuration changes, if the main AP with from AP it is wireless there are wired connection or second on Updated radio network configuration is sent to from AP by row connection, the main AP.

As an optional embodiment, whether it connect from AP real-time detection itself with the cable network of main AP lower than pre- If threshold value, if so, comparing the network quality of the second wireless uplink connection, and it is attached with a higher side.

In some special circumstances, as main AP connect it is more from AP cause it is processed slow, partially from AP occupy a large amount of bands Width, from AP, to connect network quality poor with wireless uplink is directly carried out from AP compared with the wired connection of main AP, if from AP From be wirelessly restored to it is wired may cause user's use instead when connect variation suddenly, to reduce user experience.And from AP pairs The network connection of foundation and the connection of the second wireless uplink are compared and select, and wherein network quality is higher is attached friendship Mutually, to guarantee that the network used by a user using this from AP is their ability to always the best network state guaranteed.

No matter wired connection or it is wirelessly connected, guarantees that the network quality that it is connected is that highest can guarantee to provide from AP The experience of preferable user.

As an optional embodiment, network configuration information includes configuration file, first is built with main AP for configuring The slave AP of vertical connection.

In hypotactic equipment, after being connected usually on hardware view, it is also necessary to be adjusted separately respectively in software view A equipment, at least adjustment slave, can guarantee the normal operation of master-slave equipment.The present invention then connects using from AP and main AP After connecing, activly request configuration file, and according to the configuration file, the network configuration of adjust automatically itself, to eliminate artificial The trouble of configuration, it is more intelligent, it is more convenient to use.

Further, the connection of the second wireless uplink is independently established in building from AP, being capable of the Added Management people finder present invention The position broken down in ad-hoc network structure: it is accessed when AP main in present networks can not provide WIFI, is then main AP failure；When from AP other points can not provide WIFI, then be the AP failure；If all AP can not provide proper network connection, for upper wire Network failure or all AP whole failures.For from AP, if main AP failure, main AP the first uplink connecting fault, main AP With the connecting fault from AP, it can also voluntarily establish and be connect with the second wireless uplink of upper layer network, therefore when main AP can not When normal offer WIFI access, remain to work normally.Further, above-mentioned failure is mixed in together, main AP and it is multiple from AP can not normally provide WIFI access, then the equal failure of these AP.

As an optional embodiment, when judging whether main AP interrupts with the network connection from AP, from AP and master Whether AP transmitting-receiving heartbeat packet real-time detection network connection is interrupted.

It is capable of the operational monitoring thread of durations by heartbeat packet, compared to fully synchronized, consumes less resource It can achieve the purpose that monitoring.Simultaneously by adjusting heartbeat packet cycle time, user can satisfy to Network status difference Demand, such as adjust cycle time shorten it is short, then can fast reaction, and establish network, but it is more to consume resource；And it adjusts Cycle time increases, then can reduce to the resource occupation in networked system, networked system be run more smooth, but It is that reaction speed is slower.

Further, it is connected with each other from AP, and each selects optional uplink to connect from the more optional uplink connection of AP The best conduct uplink connection of middle network quality.

Due to the distribution of main AP network bandwidth be allocated according to it with the agreement from AP, if agreement be according to from The request distribution network bandwidth of AP occupies biggish Internet resources then the resource that some is requested from AP is more, and main AP is main The network connecting request from AP is managed, other Internet resources obtained from AP and Internet resources may be poor.And it will be from AP After interconnection, allow there are multiple uplink connection types from AP, and voluntarily select better connection type and interface, entire Main AP- adds new node from the network connection of AP, and voluntarily optimization is main AP- from AP- from forms such as AP, and network shunt is voluntarily Optimization can be handled larger Internet resources.Its from AP in addition to providing WIFI access service, partially from AP assist main AP into Row network management saves the computing resource of main AP, reduces the processing task of winner AP, it is not easy to it is existing card machine etc. occur As.Node more than second level from AP as main AP assists main AP to carry out network resource management, so that the network structure in networking It is more stable, service quality is higher.

As shown in figure 4, the present invention also provides a kind of wireless network group network systems comprising:

Main AP and Access Point is used as to provide a user WIFI from AP in the present invention, while main AP is as from AP's Primary connecting node guarantees networking when all AP are worked normally to provide the network of uplink from AP, is capable of providing normal Network connection.

Meanwhile from the main AP of AP proactive contact, share the workload of main AP, can be regarded as by the function of AC in the prior art into Row divides and classification, and different functions has been respectively allocated to main AP and from AP, has enabled different functions distributed Execution, and consume the resource of distinct device, it is more stable, reasonable.

Optionally, main AP is established with from when the network connection of AP, and main AP team is verified from the connection permission of AP

For example, main AP receives authentication information and verification from AP, and network connection is established if verifying successfully, is otherwise returned Return failure information.It is verified by authentication information, it is safer.

As an optional embodiment, the network configuration includes the radio network configuration of main AP, when from AP and master When the cable network disconnecting of AP, the second wireless uplink is established with main AP from AP and is connect.

When from the cable network disconnecting of AP and main AP, from AP if can not can not normal work if re-accessing network Make, and main AP and uplink network equipment are to provide wireless access point in connection status for wireless device at this time, therefore from AP Can by obtaining the radio network configuration of main AP in advance, when cable network disconnecting, by the wireless connection point of main AP, The connection of the second wireless uplink is established, to resume work.

Further, the radio network configuration includes multiple network configurations for being wirelessly connected point, described to select net from AP Network quality, which is preferably wirelessly connected, a little to be connected；It is periodically detected the network quality that second wireless uplink connects from AP, if institute It is poor to state network quality, then switches to other and is wirelessly connected point.

For example, it is wirelessly connected in point, generally there is the access way of 2.4G and 5G, what different connection types was applicable in Distance, network speed are different.Therefore, the network quality that can be adjusted according to actual needs to demand is preferable, to guarantee to connect from AP Enter the access point that fitting needs, guarantees to work normally from AP.

It include the radio network configuration of main AP and upper layer network equipment in network configuration, so that when the circuit network company from AP After connecing, main AP can be connected also and can connect the upper layer network equipment of main AP.It ensure that the network area is fault-tolerant, prevent event What is hindered is with better function: after main AP from the wired connection of AP with breaking down, still can pass through wireless and main AP from AP and carry out Connection；After main AP or main AP and upper layer network equipment disconnecting, it still can pass through the nothing of upper layer network equipment from AP Line configuration file is attached with upper layer network equipment.

Meanwhile when being selected from AP, it is attached, can preferably guarantees for judgment criteria according to network quality The network quality of network is continuously in optimum state.

In addition, of the invention be not directly connected upper layer network equipment from AP, it is only poor in failure or network quality Situation is just attached, and is capable of the load of biggish reduction upper layer network equipment, is formed more flexible connection type.

As an optional technical solution, it is described from AP establish the second wireless uplink connection after, have described in real-time detection Whether line network connection restores, if cable network connection restores, switches to from second wireless uplink connection wired Network connection.

Main AP is connect with from the uplink of AP, main AP can influence the experience that user accesses WIFI, therefore, the net of connection Network quality is particularly important.In existing connection type, wired connection is small as crosstalk, network speed is fast and switch rate is low connection side Formula, can significantly more efficient offer WIFI to providing better user experience, therefore, above-mentioned connection carries out or extensive connecting After multiple, preferably carried out by wired mode.

For example, operation has Server program on main AP, and operation has Client program and Check program from AP.

Its Server program operates on main AP: on receiving sub- AP Client program send configuration synchronization request it Afterwards, it obtains the WIFI configuration information of main AP and the WIFI configuration information of main AP is sent to sub- AP.

Its Client program operates on sub- AP: after group AP is connected to main AP, Client program is actively sent to main AP Synchronization request is configured, and the configuration got from Server program is preserved recovery network when disconnection as cable to make With.

Its Check program operates on sub- AP: it can detect network state in real time, when discovery cable disconnection causes net When network interrupts, wireless uplink connection is established using the WIFI of preservation configuration actively to restore network.While if it find that Cable connection restores, then active disconnection of wireless uplink connects and uses more reliable and more stable wired connection as uplink.

Further, on physical layer, main AP accesses Internet network by wired connection router, from AP by having Line or the main AP of wireless access.

On logic level, operates in establish by communication protocol with the Server operated on main AP from the Client of AP and lead to Letter connection.Server may have access to being locally configured for main AP, obtain WIFI SSID, password and cipher mode of main AP.Client is received After the WIFI configuration information replied to Server, local data base is stored the data to, main AP modifies WIFI configuration information later Also it can notify to modify correspondence database information from AP by communication protocol.Operating in can periodic detection from the Check program on AP Uplink connection type and state will use the WIFI configuration of the main AP of data preservation when detecting that uplink cable disconnects Information restores network to establish wireless relay connection.It can active disconnection of wireless company when detecting that wired connection is restored It connects, can prevent network from forming loop in this way.

Check is the timing routine operated in from AP, and 10 seconds kinds of program detect a WAN mouthfuls of states.When detecting When WAN mouthfuls of cables disconnect, it is first determined whether there are wireless uplink connection, if there is so illustrating that current extensions AP makes With wireless uplink mode, program continues to test WAN mouthfuls of states.It is connected if there is no wireless uplink, then program can read Then the WIFI configuration stored in interaction establishes wireless the second wireless uplink connection according to this WIFI configuration to restore network.

As shown in figure 5, being Client and Server interaction figure.

After Client establishes TCP connection to Server according to the IP and certain port of main AP, issues Auth and authenticate message, it is subsidiary Authentication information；

Server verifies the authentication information received；Authentification failure then replys AUTH FAILED message to Server, Client receives backed off after random；It authenticates and successfully then replys AUTH OK to Client, Client is sent out to Server after receiving the message REQUEST WIFI SETTING request is played, Server is received and WIFI configuration information is returned to Client after this is requested.
