Description
The present invention relates to a terminal and an operation method thereof.
The Wi-Fi access point broadcasts a beacon frame including a service set identifier (SSID) and configuration information.
This service set identifier is a 32-byte long text string. Therefore, this service identifier can follow various text encoding formats.
However, most current operating systems (OSs) support only one text encoding format.
In this situation, when the terminal receives the beacon frame including the service set identifier and the setting information, the terminal stores the service set identifier as a profile.
However, when the terminal later displays the stored profile, the terminal abnormally displays a service set identifier of a text encoding format that the terminal does not support. In addition, when the terminal later accesses the access point through the stored profile, the terminal inquires the relevant setting information by using the abnormal service set identifier, so that the related setting information cannot be found and thus the access point cannot be accessed. .
An object of the present invention is to provide a terminal and a method of operating the same, which support service set identifiers of various text encoding formats without user manipulation.

And at least one of the second text string and the third text string includes an identification character for identification of a text encoding format.
According to another embodiment of the present invention, a terminal based on a first text encoding format includes a communication unit configured to receive a first text string from a communication device; Generate a second text string comprising the first text string when the recognized encoding format is the first text encoding format, and convert the first text string when the recognized encoding format is the second text encoding format; A first text encoding format converter configured to convert the first text encoding format to generate a third text string; And a user interface providing unit configured to store the second text string or the third text string provided by the first text encoding format converter in the memory, wherein at least one of the second text string and the third text string includes: Contains an identifying character for identification of the text encoding format.
Although the text string has two or more encoding formats, and different encoding formats are used in terms of storage and use, or in display and usage, the terminal according to the embodiment of the present invention provides texts of various text encoding formats without user manipulation. It can support strings.
In particular, a terminal according to various embodiments of the present disclosure may support service set identifiers of various text encoding formats without user's manipulation.

The
5 is a flowchart illustrating a method of recognizing a text encoding format according to an embodiment of the present invention.
KSC5601 Korean display system is as follows. In other words, Korean characters according to KSC5601 are represented by a total of 2 bytes using the ASCII extended area where the first bit of the byte is 1. For example, 'ga' is represented by 0xB0A1, 'angle' is represented by 0xB0A2, and 'liver' is represented by 0xB0A3. There is no special pattern for the KSC5601.
Table 1 shows a part of the KSC5601 Korean code table.
In the UTF-8 encoding format, the representation and length differ depending on the code area. Since Hangul is assigned to 0xAC00 ~ 0xD7AF area, it follows 16 bits code expression method corresponding to 0x0800 ~ 0xFFFF area.
Table 2 shows the encoding schemes according to the code areas of UTF-8.
According to Table 2, 16 bits code is inserted in the form of 3 bytes (1110xxxx 10xxxxxx 10xxxxxx).
For example, the Hangul 'I' is '0xB098' and the binary number is '0b10110000 10011000' in the Unicode area.
When converted to UTF-8 format, it becomes '11101011 10000010 10011000'.
Thus, if the first bit of the start byte of a text string conforming to UTF-8 is 0, the start byte represents one byte of character. Also, if the first 3 bits of the start byte are 110, the next 1 byte starts with 10. Also, if the first 4 bits of the start byte are 1110, the next 2 bytes start with 10.
As described above, since the text string conforming to UTF-8 has a specific pattern, the encoding format of the text string can be recognized through this pattern.
When the first text
If the variable byte is 0 (S305), the first text
If the nth byte of the SSID starts with 0 (S307), the first text encoding
On the other hand, if the nth byte of the SSID does not start with 0 (S307), the first text
If the n th byte of the SSID starts with 110 (S309), the first text
If the nth byte of the SSID does not start with 110 (S309), the first text
If the nth byte of the SSID starts with 1110 (S313), the first text encoding
If the nth byte of the SSID does not start with 1110 (S313), the first text
If the nth byte of the SSID starts with 11110 (S317), the first text encoding
If the nth byte of the SSID does not start with 11110 (S317), the first text
If the n th byte of the SSID starts with 111110 (S321), the first text
If the nth byte of the SSID does not start with 111110 (S321), the first text
If the n th byte of the SSID starts with 1111110 (S325), the first text
On the other hand, if the nth byte of the SSID does not start with 111110 (S321), the first text
The first text
If the variable n is greater than the length of the SSID (S333), the first text
On the other hand, if the variable n is smaller than the length of the SSID (S333), the first text
If the variable byte is not 0 (S305), since the current n th byte is related to the previous (n-1) th byte, the first text
Next, the effects of the present invention will be described with reference to FIGS. 6 and 7.
6 illustrates a problem of solving the SSID encoding problem as a menu instead of applying the embodiment of the present invention.
As shown in FIG. 6A, instead of applying the embodiment of the present invention, a 'Unicode (UTF-8) Apply' menu may be inserted into the setting. However, the user may not be able to accurately recognize the purpose of such a menu. In addition, even if the use of this menu is known, it causes inconvenience.
As shown in FIG. 6B, when the 'Unicode (UTF-8) Apply' menu is deactivated, only the SSID of the KSC5601 encoding format is normally displayed, and the
As shown in FIG. 6C, when the 'Unicode (UTF-8) apply' menu is activated, only the SSID of the UTF-8 encoding format is normally displayed, and the SSID of the KSC5601 encoding format is not displayed. Therefore, the
7 shows the effect when the embodiment of the present invention is applied.
As shown in FIG. 7A, when the embodiment of the present invention is applied, the 'Unicode (UTF-8) application' menu is unnecessary.
Nevertheless, as shown in FIG. 7B, both SSID of the UTF-8 encoding format and SSID of the KSC5601 encoding format are normally displayed, and the
Although the Korean SSID has been described above, if the SSID of a language other than Korean has two or more encoding formats, the present invention can be applied.
In addition, although the above description focuses on the SSID, the present invention can be applied if a text string other than the SSID has two or more encoding formats, and different encoding formats are used in terms of storage and use or in terms of display and use. have.
According to an embodiment of the present invention, the above-described method can be implemented as a code readable by a processor on a medium on which a program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .
The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
