Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Noting, the aspects described below in conjunction with the drawings and specific embodiments is merely illustrative of, and is understood not to protection scope of the present invention is carried out any restriction.
Wireless communication system is widely deployed to provide such as example various types of Content of Communication such as voice, data.Exemplary radio communication system can be able to by shared free system resources (such as, bandwidth, transmitting power ...) support the multi-address system of communication with multiple users.Fig. 2 shows the schematic diagram of the system that can adopt the solution of the present invention.
The network 210 illustrated in Fig. 2 can be any network system needing network access parameters to access, for instance adopt Ultra-Mobile Broadband (UMB), IEEE802.11 (Wi-Fi), IEEE802.16 (WiMAX), IEEE802.20,Or the like radiotechnics.In addition, network 210 may also include equity (such as, moving movement) self-organizing (adhoc) network system being frequently used non-matching without licensed spectrum, 802.xx WLAN, bluetooth and any other short distance or long-range wireless communication technology.
Interactive device 220 and non-interactive type equipment 230 is included at network 210.Here, interactive device 220 is in the state accessing network 210.Such as, the user of interactive device 220 have input the access parameter for accessing network 210 artificially already by with the mutual of interactive device 220, thus obtaining being successfully accessed network 210.Typically, network 210 can be WiFi WLAN, and the working frequency range of network 210 is 2412MHZ-2484MHZ or 5170MHz-6100MHz.Network access parameters can be WiFi account and the WiFi password of network 210.In the access state, interactive device 220 can obtain various types of service such as voice, data by network 210.
Although non-interactive type equipment 230 is also in network 210, but non-interactive type equipment 230 is due to cannot be mutual with user, so network access parameters cannot be inputted artificially.Accordingly, it would be desirable to come for its configuration access parameter by interactive device 220.Exemplarily, non-interactive type equipment 230 can be robot voice module.
Fig. 1 illustrates the access parameter allocation plan being traditionally used for non-interactive type equipment.
As it is shown in figure 1, traditional allocation plan mainly includes following step:
S101: first interactive device disconnects from network；
S102: non-interactive type equipment switches to ap mode；
S103: interactive device is connected to be in the non-interactive type equipment of ap mode；
S104: interactive device sends access parameter to non-interactive type equipment；
S105: non-interactive type equipment from be in ap mode non-interactive type equipment disconnect；
S106: interactive device reconnects to network；
S107: non-interactive type equipment switches to normal STA mode；
S108: non-interactive type equipment accesses network.
From the foregoing, it will be observed that in order to reach configuration purpose, it is necessary to the AP that constantly switching WIFI and login equity end are set up, the switching of non-interactive type equipment is frequently as seen from the figure, and the spent time includes the time of 2 WPA authentications and DHCP, and operates relative complex.
Fig. 3 shows the block diagram of non-interactive type equipment 230 according to an aspect of the present invention.
Exemplarily, this network 210 can be in compliance with the WLAN of 802.11 agreements.Typically, the working frequency range of network 210 is 2412MHZ-2484MHZ or 5170MHz-6100MHz.As it was previously stated, non-interactive type equipment 230 is before accessing network 210, it is impossible to obtain network service.Because the data of transmitting-receiving are all encrypted through WPA/WPA2 on the working frequency range of network 210, actual content for unsuccessful access network 210 non-interactive type equipment 230 now and invisible.
While it is true, non-interactive type equipment 230 is able to listen to the signal on the working frequency range of network 210.Specifically, non-interactive type equipment 230 can include transceiver module 231.Transceiver module 231 is responsible for the communication of non-interactive type equipment 230 and external entity, it is possible to be sent out signal, it is also possible to receive signal.The operating frequency of transceiver module 231 is identical with the working frequency range of network 210, so as to communicate in network 210.Therefore, the transceiver module 231 of non-interactive type equipment 230 can monitor the wireless signal in the working frequency range of network 210.In other words, the equipment of all access networks 210, the signal sent including interactive device 220 can be received by non-interactive type equipment 230, although can not correctly understand these signals received before not accessing network 210 according to traditional scheme non-interactive type equipment 230.
According to the solution of the present invention, pass on access parameter by the wireless signal sending " special " to the non-interactive type equipment 230 of hope acquisition access parameter by interactive device 220.This special wireless signal includes the information that correctly can be identified by non-interactive type equipment 230, thus passing on access parameter to it.
Owing to the signal of network 210 is all encrypted through WPA/AWPA2, so the information that non-interactive type equipment 230 can correctly identify only has the length of Frame in signal.According to an aspect of the present invention, by sending, to non-interactive type equipment 230, the signal that data length " meaningfully " changes, access parameter is passed on to non-interactive type equipment 230.
For this, non-interactive type equipment 230 initially enters monitoring pattern, transceiver module 231 monitor the wireless signal in the working frequency range of network 210 in the listen mode.But, the working frequency range of network 210 is likely to have some wireless devices to launch signal.Therefore, non-interactive type equipment 230 is firstly the need of identifying the signal in order to pass on access parameter that interactive device 220 sends from these numerous wireless signals.
Non-interactive type equipment 230 can include search module 232, and search module 232 can be used for searching out Target Wireless signal in the middle of these wireless signals listened to, and this Target Wireless signal is the signal for passing on access parameter that interactive device 220 sends.For identification purposes, Target Wireless signal is the wireless signal with feature data frame.That is, search module 232 searches for Target Wireless signal by searching for the signal with feature data frame.
As mentioned above, owing to non-interactive type equipment 230 does not also access network 210, therefore cannot wireless signal on the working frequency range of decryption network 210, but in wireless signal, the length of Frame may identify which, therefore, it can by identifying that in signal, signal is understood by the length of Frame.
According to an aspect of the present invention, feature data frame can be continuous print predetermined number Frame, and the length of these Frames presses known rules change.Such as, feature data frame can be the Frame that length is incremented by gradually according to predetermined amplification.This feature of feature data frame can be known by non-interactive device 230 in advance, and therefore, as long as search module 232 retrieves the wireless signal with feature data frame, can know this wireless signal is Target Wireless signal.
Each Frame can include head and payload.The length of head is fixing, and therefore the length change of Frame is to cause owing to the length of payload changes.The head of Frame is expressly to send, and payload portions is through encryption.Payload is regarded as the encryption version of sent data.Length variable quantity after each data are encrypted is certain, such as, if length one byte of difference of two data, then the two data are through encrypting the payload portions respectively as two Frames, and the length of the payload of the two Frame also differs a byte.So, the transmission of feature data frame can be realized by regulating the length of the sent data of each Frame at transmitting terminal.
Exemplarily, such as interactive device 220 can send 5 continuous print Frames, the payload portions of first Frame is formed by the data encryption of 1 byte length, the payload portions of second Frame is formed by the data encryption of 2 byte lengths, the payload portions of the 3rd Frame is formed by the data encryption of 3 byte lengths, the payload portions of fourth data frame is formed by the data encryption of 4 byte lengths, and the payload portions of the 5th Frame is formed by the data encryption of 5 byte lengths.Owing to the length increment after encryption is identical, so the length of the payload of these 5 Frames is also be incremented by 1 byte one by one.
Such 5 Frames can be considered feature data frame, because their length presses known rules change, namely the size of each Frame is incremented by 1 byte gradually.
Feature data frame is identified thus after searching Target Wireless signal, in order to save process resource, transceiver module 231 can lock the frequency of this Target Wireless signal and be received at search module 232.The signal sent in the frequency of Target Wireless signal is likely to also there is multiple signal source, it is therefore desirable to filter out the signal being not from interactive device 220.
For this, search module 232 can determine the source address of this Target Wireless signal from the head of feature data frame, the such as MAC Address of interactive device 220, thus filtering out the wireless signal being not from this source address, thus can obtain the follow-up carrier data frame of interactive device 220.
So-called carrier data frame is to send the volume of data frame being positioned in the Target Wireless signal of interactive device 220 after feature data frame.The regular change of length of these Frames, non-interactive type equipment 230 obtains network access parameters by understanding the change of this length.
As it is shown on figure 3, non-interactive type equipment 230 can include decoder module 233, perform decoding with the length of carrier data frame each in based target wireless signal, to obtain the access parameter accessing network.Specifically, decoder module 233 can determine access parameter based on the physical length of the payload of each carrier data frame.The physical length of payload here is the length of the data before unencryption that transmitting terminal sends.
In one example, decoder module 233 can include length computation module 2331, determines encryption length increment for feature based Frame.As it was previously stated, feature data frame can be the continuous data frame that predetermined number length changes according to known rules.The characteristic of feature data frame can be that non-interactive device 230 is known, for instance the physical length of the payload portions of each Frame in feature data frame, namely the length of the data before payload not encrypted can be known.Length computation module 2331 can deduct the physical length before its encryption to obtain this encryption length increment by length after the encryption by the payload of this feature data frame.
As it was previously stated, data are constant at the encryption length increment after encryption, therefore, length computation module 2331 can determine the physical length before the encryption of the payload of each carrier data frame based on this encryption length increment.
Decoder module 233 may also include length decoder module 2332, and this length decoder module 2332 can decode significant information based on the physical length of the payload of each carrier data frame.
In one example, length decoder module 2332 the physical length decoding of payload of first carrier data frame after feature based Frame can obtain the information of number of carrier data frame, in order to knowing has in Target Wireless signal to have how many carrier data frames.After the number learning carrier data frame, remaining carrier data frame can be decoded.
Specifically, length decoder module 2332 can obtain a corresponding decoded information fragment based on the physical length decoding of the payload of each carrier data frame in residue carrier data frame.Each decoded information fragment includes control bit and carrier information, and control bit indicates the attribute of carrier information associated there.Decoder module 233 may also include composite module 2333, optionally combines the carrier information of each decoded information fragment to obtain access parameter for the attribute indicated by the control bit based on each decoded information fragment.
In one example, the attribute of control bit instruction includes WiFi account attribute and WiFi cryptographic properties, and this represents the part that carrier information associated therewith is the part of WiFi account or WiFi password.Therefore, all carrier informations of WiFi account attribute can be sequentially connected in series the WiFi account of the part using composition as access parameter by composite module 2333, are additionally sequentially connected in series all carrier informations of WiFi cryptographic properties to form the WiFi password of the another part as access parameter.
In one example, the attribute of control bit instruction also includes check code attribute, and this represents that carrier information associated therewith is check code.This check code can be used to WiFi account that early decoding is obtained and WiFi password performs verification.
Correspondingly, non-interactive type equipment 230 can include correction verification module 234.After decoding obtains check code, correction verification module 234 can perform verification based on the WiFi account that decoding is obtained by this check code and WiFi password.Only after verifying successfully, transceiver module 231 just can access network 210 based on WiFi account and the WiFi password through verification.
In one example, the attribute of control bit instruction may also include random number attribute, to represent that corresponding carrier information is for the random code being associated with this network configuration.After verifying successfully, this random code can be sent the source address to Target Wireless signal by transceiver module 231, and namely interactive device 220 is to confirm being properly received of access parameter.
In the present invention, access parameter information is passed on by the change of data length.For example, it is assumed that the greatest length of data is 512 bytes, then can be changed the carrier information carrying log511=9 bit long by length every time.And the size needed for representing a character is only log127=7 bit, remaining 2 bits can be used to the control bit as 4 kinds of different conditions.Such as 01 represents transmission WIFI account number, and 00 represents transmission WiFi password, and 10 expressions send check code etc..
It is now assumed that WiFi account number is LINK001, WiFi password is 12345678.Then the final carrier data sent is LINK001ab12345678, and wherein ab is every time different random number, is used for differentiating every time different configuration processes.To send " L ", the overall information passed on is: 011001100, and wherein " 01 " is control bit, represents that the carrier information being associated is WiFi password, and " 1001100 " are the ASCII character binary representations of ' L ', for carrier information.Therefore user program sends the actual size of data is 011001100=204.The like, to send follow-up each numeral or letter.
Fig. 4 shows the flow chart that non-interactive type equipment according to an aspect of the present invention accesses the method 400 of network.As shown in Figure 4, method 400 can comprise the following steps.
Step 401, monitors the wireless signal in the working frequency range of network in the listen mode.
In one example, this network is WLAN, and the working frequency range of network is 2412MHZ-2484MHZ or 5170MHz-6100MHz.
Step 402, with the Target Wireless signal of feature data frame in the middle of search wireless signal.
In the present invention, feature data frame is continuous predetermined number the Frame that respective length changes by known rules.In one example, after searching Target Wireless signal, it is possible to determine the source address of Target Wireless signal from the head of feature data frame, for instance the MAC Address of transmitting terminal, then lock the frequency of this Target Wireless signal to perform reception, process power with saving.Then, after filtering the wireless signal being not from this source address to obtain the carrier data frame of this Target Wireless signal.
In step 403, based target wireless signal, the length of each carrier data frame performs decoding to obtain the access parameter accessing network.
In one example, this decoding process can include being primarily based on feature data frame and determines encryption length increment.Such as, the physical length before the encryption of the payload of feature data frame is known, then length after the encryption of the payload of feature data frame can deduct the physical length before its encryption to obtain encryption length increment.Thus, the physical length of the payload of each carrier data frame can be determined based on this encryption length increment.
Access parameter may finally be determined based on the physical length of the payload of each carrier data frame.In one example, the physical length decoding of the payload of first carrier data frame carrier data frame number information can be obtained after feature based Frame, the number of this carrier data frame number information instruction carrier data frame.
After knowing the number of carrier data frame, corresponding decoded information fragment can be obtained based on the physical length decoding of the payload of each carrier data frame in residue carrier data frame.Each decoded information fragment includes control bit and carrier information, and control bit indicates the attribute of carrier information associated there.
Thus, the carrier information of each decoded information fragment can optionally be combined to obtain access parameter based on the attribute indicated by the control bit of each decoded information fragment.
Such as, the attribute of control bit instruction includes WiFi account attribute and WiFi cryptographic properties to represent that corresponding carrier information is for WiFi account and WiFi password respectively.Correspondingly, can be sequentially connected in series all carrier informations of WiFi account attribute to form the WiFi account of the part as access parameter, additionally be sequentially connected in series all carrier informations of WiFi cryptographic properties to form the WiFi password of the another part as access parameter.
Again such as, the attribute of control bit instruction also includes check code attribute to represent that corresponding carrier information is for check code.Correspondingly based on check code, WiFi account and WiFi password can be performed verification.In response to verifying successfully, then access network based on this WiFi account and WiFi password, otherwise abandon this WiFi account and WiFi password.
Again such as, the attribute of control bit instruction also includes random number attribute to represent that corresponding carrier information is for the random code being associated with this network configuration.In this case, in response to verifying successfully, can by the source address of random code transmission to this Target Wireless signal to confirm being properly received of access parameter.
In step 404, access this network based on access parameter.
Although said method is illustrated for making explanation simplify and is described as a series of actions, it should be understood that and understand, these methods not order by action is limit, because according to one or more embodiments, some actions can occur in different order and/or with from depicted and described herein or not shown herein and describe but other actions that it will be appreciated by those skilled in the art that occur concomitantly.
Fig. 5 shows the configuration schematic diagram of the network access parameters of the non-interactive type equipment according to the solution of the present invention.As it can be seen, the configuration of the network access parameters of the present invention mainly includes following several stages:
S501: send access parameter；
S502: receive and decode access parameter；
S503: receive, notifies transmitting terminal；
S504: connect WiFi.
It can be seen that interactive device has only to send SSID and encrypted message in current network conditions, the information entrained by data after decoding WPA encryption by the algorithm of non-interactive type equipment can complete information transmission.In this process, user remains that network connects without frequently cutting off.Therefore the time window transmitted can obtain huge compression, also can ensure its safety during transmission data.
The invention provides a kind of low cost, quickly, the method that safety networks.Low cost is embodied in the existing radio band of use, it is not necessary to extra other wireless signal transceivers of increase.The flow process being quickly embodied in whole configuration has only to 5 to 10 seconds, and customer-side is simple to operate, have only to input WIFI password then send, and traditional approach needs user to switch focus for twice and embedded device switches focus for twice, the get off people of skilled operation of whole flow process also to spend 3 to 5 minutes.Short being difficult to is eavesdropped at safety body present transmission flow interval.
