Embodiment
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this specification can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by embodiments different in addition, and the every details in this specification also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.It should be noted that, when not conflicting, the feature in following examples and embodiment can combine mutually.
It should be noted that, the diagram provided in following examples only illustrates basic conception of the present invention in a schematic way, then only the assembly relevant with the present invention is shown in graphic but not component count, shape and size when implementing according to reality is drawn, it is actual when implementing, and the kenel of each assembly, quantity and ratio can be a kind of change arbitrarily, and its assembly layout kenel also may be more complicated.
As described in the background art, in current standard agreement, what fill in the SSID mono-of beacon frame (i.e. Beacon frame) and probing response frame (i.e. ProbeResponse frame) is character string, this character string is not specified to be which kind of coding, like this, we think that coding is ASCII character usually, this is when using English SSID, can not have problems, but when we use Chinese SSID, just there is problem, such as AP is using the coding of UTF-8 as Chinese SSID, and the coding that STA gives tacit consent to Chinese SSID is unicode, the SSID at this time shown on STA will be mess code.The present invention, just based on this, provides a kind of coding method of service set, code device, coding/decoding method and decoding device.
Refer to Fig. 1, the invention provides a kind of coding method of service set, the coding method of described service set comprises the following steps:
S11, adopts pre-arranged code form to encode to service set;
S12, judges whether comprise Chinese character in described service set;
If comprise Chinese character in described service set, then perform step S13, WAP (wireless access point) specifies the coded format of described service set when sending service set.
Particularly, in the present embodiment, the step of concrete prescribed coding form comprises: WAP (wireless access point) adds default IE (i.e. VendorSpecificIE) in Beacon frame and ProbeResponse frame; The coded format of service set is specified in default IE (VendorSpecificIE).
It should be noted that, in VendorSpecificIE, ASCII character must be adopted to identify the coded format of SSID, if take Chinese, will problem be caused, because the coded format of the Chinese character in VendorSpecificIE cannot be judged.
If when not comprising Chinese character in described service set, then perform step S14, WAP (wireless access point) does not specify the coded format of described service set when sending service set.That is, if do not comprise Chinese character in described service set, so, can conventionally in method encode, do not need to specify coded format.
In the present embodiment, by judging service set, when comprising Chinese character in service set, increase the step of its prescribed coding, by such mode, effectively can avoid the Confused-code caused due to the coded format of follow-up None-identified service set, and then improve versatility and the flexibility of service set.
The present invention also provides a kind of code device of service set, and with reference to figure 2, the code device 1 of described service set comprises:
Coding module 11 is encoded to service set for adopting pre-arranged code form;
First judge module 12 is for judging whether comprise Chinese character in described service set;
When coded format designated module 13 for comprising Chinese character in described service set, specify the coded format of described service set.
In the present embodiment, described coded format designated module comprises: adding device and designating unit (not shown).Described adding device is used for adding VendorSpecificIE in Beacon frame and ProbeResponse frame; Described designating unit is used for the coded format of specifying service set in VendorSpecificIE.
In the present embodiment, the course of work of the code device of service set is corresponding with the coding method of aforementioned service set identifier, does not repeat them here.
The present invention also provides a kind of coding/decoding method of service set, and with reference to figure 3, the coding/decoding method of described service set comprises the following steps:
S21, terminal equipment receives Beacon frame and ProbeResponse frame;
S22, judges whether comprise VendorSpecificIE in described Beacon frame and ProbeResponse frame;
If comprise VendorSpecificIE in described Beacon frame and ProbeResponse frame, then perform S23, judge the coded format whether comprising service set in described VendorSpecificIE;
If comprise the coded format of the service set of specifying in described VendorSpecificIE, then perform S24, terminal equipment is decoded according to the coded format of the service set of specifying.
In the present embodiment, if do not comprise VendorSpecificIE in described Beacon frame and ProbeResponse frame, then perform S25, terminal equipment is decoded to service set according to ASCII fromat.
Correspondingly, if do not comprise the coded format of the service set of specifying in described VendorSpecificIE, then perform S25, terminal equipment is decoded to service set according to ASCII fromat.
In a particular application, if when WAP (wireless access point) (AP) initiates association to certain SSID, need to add VendorSpecificIE equally in disassociation frame and authentication frame, comprising the Beacon frame that receives of content Ying Yuqi or ProbeResponse frame in VendorSpecificIE consistent.Like this, namely by obtaining the coded format in VendorSpecificIE, and the coded format of specifying is used to carry out decode operation to SSID.
In addition, when the SSID coded format that the terminal STA (such as mobile phone) that SSID shows demand is supported and the coded format received are inconsistent, then need first to carry out transcoding, such as STA support Chinese time Unicode, and the SSID received in Beacon frame is UTF-8 (UTF-8 form is known by VendorSpecificIE), then STA needs the SSID SSID of UTF-8 form being first transcoded into Unicode format, then shows, can avoid mess code like this.
The present invention also provides a kind of decoding device of service set, and with reference to figure 4, the decoding device 2 of described service set comprises:
Receiver module 21 is for receiving Beacon frame and the ProbeResponse frame of WAP (wireless access point) transmission;
Second judge module 22 is for judging whether comprise VendorSpecificIE in described Beacon frame and ProbeResponse frame;
When 3rd judge module 23 for comprising VendorSpecificIE in described Beacon frame and ProbeResponse frame, judge the coded format whether comprising service set in described VendorSpecificIE;
Decoder module 24, for when comprising the coded format of the service set of specifying in described VendorSpecificIE, is decoded according to the coded format of the service set of specifying.
In the present embodiment, when described decoder module also for not comprising VendorSpecificIE in described Beacon frame and ProbeResponse frame, according to ASCII fromat, service set is decoded; And, when described decoder module also for not comprising the coded format of the service set of specifying in described VendorSpecificIE, according to ASCII fromat, service set is decoded.
In sum, the coding method of service set of the present invention, code device, coding/decoding method and decoding device, by increasing the appointment service set comprising Chinese character being carried out to coded format, effectively can avoid the Confused-code because coded format disunity causes, thus improve versatility and the flexibility of service set.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
