FIG. 2 is a flow chart showing a wireless Internet contents access method
using contents access numbers according to the present invention. Referring to
FIG. 2, the wireless Internet contents access method consists a first step S10 of
converting a numeral, a combination of a numeral and a special symbol or a
character inputted by a mobile into a domain name system using a search
application program, a second step S12 of inquiring of the wireless Internet
contents DNS server about the DNS in a DNS message format, a third step S14
of receiving NAPTR records in response to the inquiry from the wireless Internet
contents DNS server, and a fourth step S16 of accessing a wireless Internet contents access numbers extracted from the wireless Internet contents DNS
server or outputting a list.
The respective steps of the wireless Internet contents access method will
now be explained in more detail.
In the first step S10 of converting a numeral, a combination of a numeral
and a special symbol or a character inputted by a mobile communication device
into a domain name system using a search application program, the wireless
Internet contents access system receives information of functions of each mobile
communication network operator and converts an inputted numeral, combination
of a numeral and a special symbol or character into a domain name system.
Referring to FIG. 3, the first step S10 consists a step S20 of identifying a
numeral, a combination of a numeral and a special symbol or a character, a step
S22 of confirming whether a special symbol is inputted when the numeral or
combination of a numeral and a special symbol is identified in the step S20, a
step S24 of dividing the combination of a numeral and a special symbol into a
numeral before the special symbol, the special symbol and a numeral after the
special symbol when it is confirmed that the special symbol is inputted in the
step S22, a step S26 of adding a point (.) to the end of the numeral before the
special symbol to add the top-level domain name, and a step S28 of adding a
point (.) to the end of a character when the character is identified in the step S20 o add the top-level domain name.
The second step S12 inquires of the wireless Internet contents DNS
server 600 about a DNS message. Main fields of the DNS message are set as
follows.
Inquired value: QNAME = wireless Internet contents information in the
form of FQDN (Fully Qualified Domain Name) converted in the first step S10
Record information value to be received: QTYPE = NAPTR(35)
Value setting whether inquiry is repeated: RD =1
Value setting a count of inquiries: QDCOUNT =1
Here, QNAME represents an inquired value, QTYPE denotes a response
type, RD represents whether inquiry is repeated, and QDCOUNT denotes a
count of inquiries.
The third step S14 receives NAPTR records concerning the DNS
message from the wireless Internet contents DNS server 600. Specifically, the
search application program executed in the search application system 500
receives inquiry data transmitted from the mobile communication device 400 and
inquires of the wireless Internet contents DNS server 600 about the inquiry data.
The wireless Internet contents DNS server 600 converts information in the
NAPTR format about wireless Internet contents information among the DNS
message transmitted from the wireless Internet contents DNS server 600 into a zone file.
In the fourth step S16 of accessing a wireless Internet contents access
numbers extracted from the wireless Internet contents DNS server or outputting
a list, the search application program executed in the search application system
500 confirms an ANCOUNT value of a response packet header of the wireless
Internet contents DNS server 600 for the inquiry and extracts a NAPTR record
value of a response section corresponding to the confirmed value. Here, a field
value identifying a response of a header section among the received message is
confirmed and it is confirmed whether the field value represents a definite
response. Furthermore, the NAPTR record value of the response section by the
corresponding value is extracted.
FIGS. 4A and 4B illustrate examples of the wireless Internet contents
access method using contents access numbers shown in FIG. 2. FIG. 4A is a
flow chart showing a wireless Internet contents access method using a numeral
and a combination of a numeral and a special symbol, and FIG. 4B is a flow
chart showing a wireless Internet contents access method using a character.
Referring to FIG. 4A, the search application program executed in the
search application system 500 and the wireless Internet contents DNS server
600 perform inquiry and response between them. The inquiry is carried out in
such a manner that the search application system 500 accesses wireless Internet contents search service in the step S30, inputs a wireless Internet
contents access numbers in the step S31 , and converts the wireless Internet
contents access numbers into a domain name system in the step S32 to set a
DNS message in the step S33. In response to the inquiry, the wireless Internet
contents DNS server 600 provides wireless Internet contents zone file position
information in the step S34 and extracts NAPTR RR in the step S35 to respond
to the search application system 500.
The search application system 500 receiving the response from the
wireless Internet contents DNS server 600 carries out NAPTR RR parsing in the
step S36, outputs an URL list in the step S37 and moves to a corresponding
URL in the step S38.
Referring to FIG. 4B, the search application program executed in the
search application system 500 and the wireless Internet contents DNS server
600 perform inquiry and response between them. The inquiry is carried out in
such a manner that the search application system 500 accesses the wireless
Internet contents search service in the step S41 , inputs a wireless Internet
contents access numbers in the step S42, and converts the wireless Internet
contents access numbers into a domain name system in the step S43 to set a
DNS message in the step S44. In response to the inquiry, the wireless Internet
contents DNS server 600 provides wireless Internet contents zone file position information in the step S45 and extracts NAPTR RR in the step S46 to respond
to the search application system 500.
The search application system 500 receiving the response from the
wireless Internet contents DNS server 600 carries out NAPTR RR parsing in the
step S47 and moves to a corresponding URL in the step S48.
Accordingly, the first step S10 shown in FIG. 2 corresponds to the steps
S30, S31 and S32 of FIG. 4A and the steps S40, S41 and S42 of FIG. 4B. The
second step S12 shown in FIG. 2 corresponds to the steps S33 and S34 of FIG.
4A and the steps S43 and S44 of FIG. 4B. The third step S14 of FIG. 2
corresponds to the step S35 of FIG. 4A and the step S46 of FIG. 4B. The fourth
step S16 of FIG. 2 corresponds to the steps S36, S37 and S38 of FIG. 4A and
the steps S46 and S47 of FIG. 4B.
In FIGS. 4A and 4B, particularly, when it is confirmed that a numeral or a
combination of a numeral and a special symbol is searched in the first step S10,
it is confirmed whether a special symbol is inputted. When it is confirmed that
the special symbol is inputted, the numeral and the special symbol are divided
from each other, a point (.) is added to the end of the numeral before the special
symbol to add the top-level domain name.
For example, "123#45" of the first step S10 is converted into "123.mo.kr".
Here, mo.kr is a virtual domain for explanation. When it is confirmed that a character is searched in the first step S10, as
shown in FIG. 3, a point (.) is added to the end of the character to add the top-
level domain name. For example, "character" is converted into "character.mo.kr".
Here, mo.kr is a virtual domain for explanation.
FIG. 5 is a diagram for explaining NAPTR RR parsing according to the
present invention. NAPTR RR parsing searches a service region of NAPTR RR
for a numeral, a character and a mobile communication network operator
mnemonic, and then extracts URL information to be connected to display
information in an extracted region of the searched result. Here, in the case of a
combination of a numeral and a special symbol, numeral information after the
special symbol is also extracted. The extracted final result is descending sorted
in response to the numbers of times of accessing the corresponding URL to
receive NAPTR records.
FIG. 6 illustrates a configuration of wireless Internet contents access
using DNS-based contents access numbers according to the present invention.
The mobile communication device 400 inputs a numeral, a combination of a
numeral and a special symbol or a character 402 to a display 401 using a
keypad. The wireless Internet contents DNS server 600 consists an inquiry part
601 of inquiring information about the inputted numeral, combination of a
numeral and a special symbol or character 402, and a wireless Internet contents information zone part 602 of responding to the inquiry. The wireless Internet
contents information zone part 602 receives wireless Internet contents access
information in the NAPTR format such that the information inputted in the inquiry
part 601 into a domain name format, parses NAPTR RR format to extract a list
and transmits the list to the mobile communication device 400. Here, the mobile
communication device 400 accesses a wireless Internet contents URL extracted
in the wireless Internet contents information zone part 602 or outputs the list to
the display thereof.
FIG. 7 is a flow chart showing the processes of FIGS. 4A and 4B in detail
for explaining respective steps of the wireless Internet contents registration and
access method using DNS-based contents access numbers. Referring to FIG. 7,

special symbol, "123#45" or a character in order to extract an access numbers in
the step S50 and connects to a search program executed in the search
application system 500 to provide WAP, WEB and PDA services in the step S51 ,
to convert the combination of numerals and a special symbol or character into a
domain name system in the step S52.
Here, the domain name system has a form of a combination of a numeral
and a special symbol such as "123.mo.kr" or "character.mo.kr. The domain
"character.co.kr" is a virtual domain for explanation. After the combination of numerals and a special symbol is converted into the domain name system (S52),
the domain name is inquired of the wireless Internet contents DNS server 600 in
the DNS message format, for example, "QR(O), QNAME, QTYPE=NAPTR" in
the step S53.
The wireless Internet contents DNS server 600 stores wireless Internet
contents information. In the case of the domain name of "123. mo. kr", information
is stored in the form represented in Table 1.
Table 1
<Combination numerals and special symbols>
123 NAPTR 12 100 "w" "W2U+mob:45:SKT" "!\*$!character(test.co.kr):m.test.co.kr!"
<Numeral>
123 NAPTR 12 100 "w" "W2U+mob:EXP:KTF" "!Λ.*$!character(test.co.kr):m.test.co.kr!"
<Character>
Character NAPTR 12 100 "w" "W2U+mob:UC:LGT" "!Λ.*$!123#45:m.test.co.kr!"
The wireless Internet contents DNS server 600 responds to the inquiry
in such a manner that the wireless Internet contents DNS server 600 receives
wireless Internet contents information in the NAPTR format, for example, "QR(I)1ANSWER", in the step S54. Here, the NAPTR RR format is parsed to
extract a list.
In the selection of a list according to the response to the inquiry, an
extracted phone page is accessed or the list is output in the step S55. Here, it is
possible to move to a corresponding site after selecting the list using a number,
a phone page URL and a display name.
Registration of wireless Internet contents access numbers according to
the wireless Internet contents access system and method using contents access
numbers of the present invention will now be explained.
A method of registering information of a wireless Internet contents access
numbers registers information about wireless Internet contents in the wireless
Internet contents access numbers registration server and the wireless Internet
contents DNS server using wired Internet, which is explained with reference to
FIG. 1.
In the registration of a wireless Internet contents access numbers
according to the present invention, wireless Internet contents page information
and registrant information are received through the wired Internet and
transmitted to the wireless Internet contents access numbers registration server
300.
The wireless Internet contents access numbers registration server 300 receives a URL, a wireless Internet contents access character and registrant -
information for each mobile communication network operator of wireless Internet
contents and constructs them in a database to register them. Accordingly, the
wireless Internet contents access numbers registration server 300 shown in FIG.
1 applies DNS message standard and NAPTR standard to wireless Internet
contents information, converts the wireless Internet contents information into a
URL, and registers the URL in the wireless Internet contents DNS server 600.
The registration in the wireless Internet contents DNS server 600
generates a wireless Internet contents zone file concerning the wireless Internet
contents access numbers. NAPTR RR configuration of the wireless Internet
contents zone file will now be explained with reference to Table 2 representing
NAPTR RR configuration using a combination of numerals and special symbols,
Table 3 representing NAPTR RR configuration using numerals and Table 4
representing NAPTR RR configuration using a character.
That is, the wireless Internet contents DNS server performs registration in
such a manner that a function identification value is set to a service type of a
response section to identify wireless Internet contents access information for
each function, a mobile communication network operator mnemonic value is set
to the service type of the response section to identify a mobile communication
network operator, and a URL is set to REGEXP type of the response section when wireless Internet contents are activated to check whether the wireless
Internet contents are activated.
According to the configurations of the response section of DNS-based
wireless Internet contents access service represented in Tables 2, 3 and 4, more
accurate addresses can be extracted through a mobile and service applicability
can be improved.
Tables 2, 3 and 4 representing configurations of the wireless Internet
contents access numbers registration form for each function with respect to the
response section will now be explained.
In Table 2 representing NAPTR RR configuration using a combination of
numerals and special symbols, wireless Internet contents having the same
numeral before a special symbol are converted into the same domain name and
registered in the wireless Internet contents DNS server.
For example, "123#45" and "123#67" are converted into a domain having
the same name "123.mo.kr" using "123" placed before the special symbol "#".
Table 2
To identify wireless Internet contents extracted in a domain form having
the same name, a numeral after the special symbol is set to the service type. In
other words, the NAPTR RR configuration using a combination of numerals and
special symbols divides a wireless Internet contents access numbers into a
numeral before a special symbol, the special symbol, a numeral after the special
symbol and numerals before the special symbol, which are identical to each other, are set as "W2U+mob:numeral after special symbol" to the service type.
Furthermore, to identify a mobile communication network operator, a mobile
communication network operator mnemonic value in the form of
"W2U+mob:numeral after special symbohmobile communication network
operator" is set to the service type.
The NAPTR RR configuration using numerals of Table 3 sets "EXP" to
the service type in the form of "W2U+mob:EXP" to identify wireless Internet
contents information and sets a mobile communication network operator
mnemonic value in the form of "W2U+mob:EXP:mobile communication network
mnemonic value" to the service type to identify a mobile communication network
operator.
Table 3
The NAPTR RR configuration using a character represented in Table 4
sets "UC" to the service type in the form of "W2U+mob:UC" to identify inputted
character information and sets a mobile communication network operator
mnemonic value in the form of "W2U+mob:UC:mobile communication network
mnemonic value" to the service type to identify a mobile communication network
operator.
In the meantime, the wireless Internet contents information registration
form of Table 4 is applied to the response section for the DNS-based wireless
Internet contents access service. Table 4
Table 5 represents an example of using the wireless Internet contents
access system registered in NAPTR.
