Specific embodiment
Here will in detail exemplary embodiment be illustrated, its example is illustrated in the accompanying drawings.Explained below is related to During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with such as appended The example of the consistent apparatus and method of some aspects being described in detail in claims, the disclosure.
Following for disclosure device embodiment, can be used for executing method of disclosure embodiment.Real for disclosure device Apply the details not disclosed in example, refer to method of disclosure embodiment.
Fig. 1 is the system architecture diagram of the WLAN cut-in method of the disclosure, as shown in figure 1, the method is applied to In WLAN, such as in the WLAN in one family, it is directed to wireless access node (Access Point, abbreviation AP), relaying and terminal, wherein, AP can be wireless router, and relaying can be to be successfully accessed to no Equipment in line LAN, that is, relaying is the terminal that any one is established a connection with AP.Terminal is wireless local to be accessed The equipment of net.Wherein, after terminal is successfully accessed WLAN, except completing the function of itself, relaying can also be undertaken Role, and then, as shown in figure 1, when new terminal desires access to WLAN, both can be accessed no by accessing AP Line LAN it is also possible to access WLAN by accessing relaying, with realize accessing flexibly and ensure transmission signal Quality.
Wherein, the disclosure stands in the angle of terminal and is described, and relates generally to terminal and determines when accessing WLAN Select the process that the equipment accessing is AP or a certain given trunk, the method that the disclosure is provided ensure that terminal is accessing no The quality of the signal transmission after line LAN.
Fig. 2 is a kind of flow chart of the WLAN cut-in method according to an exemplary embodiment, as Fig. 2 institute Show, the implementation procedure of the method is:
In step S101, terminal sends WLAN incoming broadcast message.
Access as a example WLAN by a mobile phone, when the mobile phone in one family needs to access this family During WLAN, access node scanning can be carried out first, that is, peripherad node sends WLAN incoming broadcast message, And carry service set (the Service Set of the AP of the WLAN of this family in this broadcast Identifier, abbreviation SSID).
Wherein, mobile phone can obtain the SSID of the AP of WLAN of this family beforehand through methods such as configurations, will Hereinafter describe in detail.
In step s 102, terminal receives the response message that at least one receiving node is sent, wherein, this response message Include the SSID of at least one receiving node.
After terminal sends WLAN incoming broadcast message, the node receiving this message will be according to itself feelings Condition is judged, if certain receiving node determines the function oneself with access node, this receiving node can send to terminal One response message, comprises the SSID of this receiving node in this response message.
In step s 103, terminal determines access node list according to the SSID of at least one receiving node, and wherein, this connects Ingress list includes AP and at least one relays, and the SSID of this at least one relaying uses preset algorithm according to the SSID of AP Calculate and obtain.
After terminal sends WLAN incoming broadcast message, as long as the AP in WLAN is in normal work shape Under state, AP can send response message to terminal, and meanwhile, in this WLAN, the node as relaying also can be to end End sends response message.In addition, some nodes in non-present WLAN are likely to receive broadcast, and to Terminal sends response message.
After terminal receives these response messages, alternative access node can be filtered out according to SSID, and shape Become access node list.Wherein, in a specific WLAN, AP has a unique SSID, and then, when certain After node accesses this WLAN and relays as one, this also has a unique SSID as the node of relaying, This SSID generates according to preset algorithm on the basis of the SSID of AP.Because terminal has got Current wireless local area in advance The SSID of the AP of net, therefore, terminal just can identify the AP in current wireless Local Area Network according to SSID and preset algorithm And relaying, and filter out the node that node in such as other WLANs etc. is unsatisfactory for requiring.
Through above-mentioned screening, the access node in the access node list that terminal is determined all is in currently wireless office Node that is in the net of domain and being accessed for terminal.
In step S104, the received signal strength indicator of AP according to corresponding to access node list for the terminal (Received Signal Strength Indication, abbreviation RSSI) and the RSSI of relaying, determines Target Access Node.
Filter out after node that is in current wireless Local Area Network and being accessed for terminal when terminal so that it may Select one to ensure that the node of Optimal Signals transmission quality and set up and this node with the RSSI according to these nodes Connection.
In the present embodiment, when terminal needs to access a WLAN, first this wireless local is determined according to SSID Wherein not only can include AP as the node of access node in net, can also include relaying, and then, then from these nodes Select the optimal node of signal transmission quality.That is, provide more alternative access node by SSID for terminal, from And ensure that terminal therefrom selects the optimal node of signal transmission quality, improve the effect that terminal accesses WLAN.
On the basis of above-described embodiment, the present embodiment is related to a kind of concrete grammar that terminal determines Target Access Node, That is, a kind of specific implementation of above-mentioned steps S104 is:
Obtain the maximum in the RSSI of the AP and RSSI of relaying in above-mentioned access node list, will have maximum RSSI AP or relaying as above-mentioned Target Access Node.
Wherein, RSSI is used to weigh the index of the intensity of receipt signal, after terminal determines access node list, The RSSI of each node in access node list can be obtained one by one, RSSI is bigger, then show to enter between terminal and this access node Laser propagation effect during row signal transmission is better, therefore, in this step, after terminal gets the RSSI of each access node, can look into Find out maximum therein, and using the Target Access Node that this accesses as terminal of the access node corresponding to this maximum.
As an example it is assumed that current terminal is a mobile phone, mobile phone is currently located at certain bedroom corner of one family, And the AP of the WLAN of this family is located at distant another bedroom corner, now, if mobile phone is directly connected to AP, Then signal quality can be weaker, and if using disclosed method, has multiple equipment to access the wireless office of this family in advance Domain net, and there is the function of relaying, then mobile phone can select a maximum node of RSSI from AP and these relayings, For example, one of parlor Intelligent lamp in the middle of this family, after mobile phone accesses this Intelligent lamp, the quality of signal transmission Significantly can be lifted than being directly accessed AP and having.
In the present embodiment, it is used as access node by selecting the maximum node of RSSI, enables to terminal and access this access After node, the quality of signal transmission is increased dramatically.
On the basis of above-described embodiment, the present embodiment is related to terminal and is connect according to the SSID determination of at least one receiving node The concrete grammar of ingress list, i.e. Fig. 3 is a kind of WLAN cut-in method according to an exemplary embodiment Flow chart, as shown in figure 3, above-mentioned steps S103 specifically include:
In step s 201, the AP at least one receiving node above-mentioned is added in access node list terminal.
With reference to the description previously for Fig. 1, AP can be regarded as the router in WLAN, i.e. wireless local Netcom Cross AP and carry out data interaction with the Internet, therefore, in this step, first AP is added in access node list, as terminal One of alternative access node.
In step S202, if the first receiving node is relaying, judge whether the SSID of the first receiving node is basis The SSID of above-mentioned AP is obtained using preset algorithm, if so, then above-mentioned first receiving node is added to above-mentioned access node row In table.
Wherein, above-mentioned first receiving node is that at least one receiving node above-mentioned, any one in addition to above-mentioned AP connects Receive node.
The current node as relaying needs to be linked in WLAN in advance, and undertakes the role of relaying, as Relaying, this node need have the SSID of oneself as AP, in the disclosure, this node can by specific preset algorithm Lai Generate the SSID of oneself according to the SSID of AP.
When terminal is when carrying out access node screening, the SSID also according to AP judges certain based on same preset algorithm Whether the SSID of node meets the requirement of the relaying SSID in current wireless Local Area Network, that is, judge this node SSID be whether Obtained according to specific preset algorithm on the basis of the SSID of AP.
In the present embodiment, terminal by with relaying generate SSID when identical preset algorithm determine whether node is can Selective access node, thus the node that goes out selected by ensureing is all relaying in current wireless Local Area Network it is ensured that selected Select the correctness of node.
In another embodiment, one kind of above-mentioned steps S202 is preferred embodiment:
Judge whether the SSID of above-mentioned first receiving node is the SSID of above-mentioned AP and combining of default suffix name, if so, Then above-mentioned first receiving node is added in the above-mentioned access node list of institute.
That is, after certain node is linked in WLAN simultaneously as relaying, this node gets AP's first SSID, and then add default suffix name in the SSID of AP.As an example it is assumed that the SSID of AP is " TEST ", preset algorithm For " adding suffix name-IOT after the SSID of AP ", then, after certain node A is as relaying, node A can be according to this pre- imputation It is " TEST-IOT " that method generates the SSID of oneself.And because SSID is a unique mark of node, therefore, node A also needs to In the form of broadcasting, peripherad node sends the SSID of generation, when another node B also serves as relaying after the meeting although presetting Algorithm is identical, but the SSID of node B needs to be different from the SSID of node A, and therefore, node B can be in the base of " TEST-IOT " Corresponding numeral is increased on plinth and is used as the SSID of oneself, for example, the SSID that node B generates is " TEST-IOT1 ", and, saves The SSID being generated also can be broadcasted by point B.By that analogy, the SSID of other nodes as relaying can be node B's On the basis of to generate respective SSID according to the principle of ascending numerical.
And it is only necessary to " be added after the SSID of AP according to preset algorithm after working as the response message that terminal receives each node Whether suffix name-IOT " comes whether decision node is alternative access node, i.e. wrap in the SSID of terminal only decision node Include the SSID of AP and whether include "-IOT " this suffix, as long as meeting this two conditions, and the SSID for node In other fields, terminal do not need to be judged.
In another embodiment, the method also includes:
If the RSSI of at least one of above-mentioned access node list node is more than the RSSI of above-mentioned Target Access Node, Above-mentioned Target Access Node is updated to the maximum node of RSSI at least one node above-mentioned.
The present embodiment executes after terminal has been successfully accessed WLAN, i.e. when terminal has been successfully accessed no After the AP of line LAN or certain relaying, when the position of terminal there occurs change, then terminal can be again to above-mentioned access node The RSSI of each node in list is judged, if the RSSI of certain node C is more than the RSSI of current Target Access Node, Then can determine compared to current Target Access Node, the signal transmission quality of terminal and node C can be higher, therefore, by mesh Tag splice ingress is updated to node C, and then, terminal is set up with node C and is connected.
Except when updating outside Target Access Node when terminal location changes, terminal can also be entered according to certain cycle The RSSI of line period judges.
In the present embodiment, after terminal accesses current Target Access Node, can be determined new further according to RSSI Target Access Node, thus ensure that the signal transmission quality between node that terminal accessed and terminal is all optimum.
On the basis of above-described embodiment, the present embodiment is related to the concrete side that terminal obtains the SSID of AP in WLAN Method, i.e. before above-mentioned steps S101, also includes:
Terminal is passed through to configure the SSID of AP and password in acquisition WLAN.
Because terminal is all that SSID according to AP determines when determining access node, therefore, before this, terminal needs The SSID of AP in WLAN to be obtained, to ensure subsequently to determine access node according to the SSID of AP.Meanwhile, terminal also needs The password of AP to be obtained, so that follow-up foundation with access node is used when being connected.
Alternatively, terminal can obtain the SSID of AP and close by specific SmartConfig mode Code.For example, for an intelligent video camera head, the application program that user can be provided using this intelligent video camera head manufacturer (Application, abbreviation APP), inputs SSID and the password of wireless local area network AP, you can this intelligence is taken the photograph in this APP As head gets SSID and the password of the AP of WLAN.
On the basis of above-described embodiment, the present embodiment is related to access section with target after terminal determines Target Access Node Point sets up the process connecting, i.e. after above-mentioned steps S104, also include:
If above-mentioned Target Access Node is above-mentioned relaying, pass through the password of the SSID and above-mentioned AP of above-mentioned relaying, with Above-mentioned relaying is set up and is connected.
When relaying accesses WLAN, relaying has got the password of the AP of WLAN, wherein, relaying The password of the AP of WLAN can be obtained by the method for above-mentioned configuration.And then, if certain terminal needs to access be somebody's turn to do Relay it is necessary to provide the password of the AP of this WLAN to this relaying, the password of the AP that this relaying is provided according to terminal To judge whether this terminal can be successfully accessed.
Therefore, on the basis of the password of the AP getting WLAN mentioned by configuration, when terminal has determined Going out Target Access Node is to relay and need with when relaying foundation and connecting, and terminal passes through the SSID of relaying and current wireless The password of the AP of LAN to be connected with relaying foundation.
