Description

Wireless Internet Access System {System for providing wireless internet service}

The present invention relates to a wireless Internet access system, and more particularly, in a wireless Internet access using a mobile communication terminal, a public telephone network (PSTN) can be used to easily use the wireless Internet without passing through a mobile network operator. The present invention relates to a wireless internet access system.

As wireless mobile communication is rapidly spreading, various additional services other than voice calls are gradually expanding its scope. The most representative of these is the wireless Internet. That is, it provides various services such as email transmission and reception, WWW service, etc. by accessing the wireless Internet using a wireless mobile communication terminal without using a computer and a wired internet network.

However, the wireless Internet service provided using the wireless mobile communication terminal has the following problems. In other words, in order to receive a wireless Internet service, a user may use a wireless mobile terminal to access a wireless Internet service (eg, SK Telecom's 011, KT's 016, LG Telecom's 019, etc.). In case of 011, n.TOP, and in case of 016, are connected to Persnet). For example, when a subscriber 011 accesses www.yahoo.com through the wireless Internet, the user first connects to the wireless Internet service (n.TOP) provided by the mobile communication service company 011 through the terminal. After selecting each of the services offered by the menu on the wireless Internet service, the user can go to the corresponding site (www.yahoo.com).

In this case, the URL of the site to be accessed is entered through the keypad of the terminal, and a considerable time is required for the input of letters or numbers through the keypad. Therefore, it takes a considerable time to access a desired site, and the fee charged in this process is not small, which is a burden on the user.

In addition, this type of wireless Internet service has a problem that the content provider (CP) to provide the content service must be essentially subordinate to the network of the wireless carrier.

To improve this, there is a method of using a kind of bookmarking concept to access a wireless Internet service so that a user can select a desired site from a preset bookmark list. The same problem occurs that you must access the corresponding wireless Internet service of and if you want to access a site that is not registered in the bookmark, you must enter the URL of the site from the beginning.

On the other hand, as part of an effort to improve the problem of the character input method through the keypad of the terminal, when entering characters such as URL, as shown in Korean Patent Laid-Open No. 2001-0000877, the number corresponding to each character or URL A method of allowing input is also proposed. However, the method of inputting the number corresponding to the URL has the inconvenience of memorizing the corresponding URL and the corresponding numeric code in advance, and the method of inputting the number corresponding to each character is limited in that duplicate numbers may occur. In addition, there is still a problem in that a mobile communication service provider must be provided to receive a wireless Internet service.

The present invention has been made in view of the above-mentioned problems, and it is possible to easily and inexpensively provide a wireless Internet service without passing through the wireless mobile communication service provider side, and without inputting a URL of a desired site through the keypad of the terminal. It is an object of the present invention to provide a wireless Internet access system that can easily access a desired site.

When a predetermined number of shortcut numbers has been transmitted from the UMS server, the corresponding URL is searched for the corresponding push number along with the caller identification number. Mapping table to pass to; And a swap push server for transmitting a URL transmitted from the mapping table to a client as a swap push message, wherein the client accesses the URL through a callback of the swap push message sent by the swap push server. .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a wireless Internet access system according to an embodiment of the present invention. As shown in FIG. 1, the wireless Internet access system according to the present embodiment includes a mobile communication network 10, a public communication network (PSTN, 20), a relay server 30, a WAP gateway 40, and a content server ( 50).

The mobile communication network 10 refers to a general mobile communication network composed of a device such as a base station, a switching center, etc., which belongs to a known technology, and thus a detailed description thereof will be omitted. In addition, the public communication network (PSTN) 20 refers to a communication network that provides a service for exchanging voice data by connecting telephones of users through an exchanger, which also belongs to the known art and is not directly related to the present invention, and thus detailed description thereof will be omitted. .

In addition, the swap gateway 40 is installed in the case of providing a wireless Internet service using a WAP, and the client receives a web service through the wireless Internet by compressing and converting data through the conversion of HTTP and WSP. It refers to a general swap gateway to enable the same, and this also belongs to the prior art and is not directly related to the present invention, detailed description thereof will be omitted. This swap gateway 40 is located between the client and the content server 50.

The content server 50 is a server that stores and provides various contents, and is a server that transmits or receives data to a client-side terminal through a swap gateway 40. In the present invention, a web site to which a client intends to connect through wireless Internet is provided. Used to mean.

On the other hand, the relay server 30 is connected to the mobile communication network 10 and the public communication network 20, respectively, from the call signal of the client connected through the mobile communication network 10 and the public communication network 20 Analyzes data such as caller information and receiver identification number, finds the URL of the web site corresponding to the receiver identification number from the pre-stored mapping table, and uses the SMS described below to the mobile communication network 10 for push push. ) Send a message and display it on the client terminal. The detailed configuration of the relay server 30 is shown in FIG.

As shown in FIG. 2, the relay server 30 includes a UMS server 31, a mapping table 32, and a swap push server 33.

The UMS server 31 is a server capable of providing all types of messages such as voice, fax, and e-mail as a service, and performs a function of receiving, processing, and distributing different types of data, respectively. . The UMS server 31 receives a signal including a caller identification number and a destination identification number (shortened number input by the client) from the public telecommunication network 20 and transmits the signal to the mapping table 32 which will be described later.

The mapping table 32 is a table in which a predetermined digit number included in a predetermined digit shortcode input by a client is associated with a URL of a web site. The predetermined number of shortcut numbers input by the client may be configured in various forms, and an example thereof is illustrated in FIG. 3. Referring to FIG. 3, the shortcut number input by the client is “030301911101” and is composed of a total of 12 digits. The first three digits 030 of the abbreviated number is a UMS identification number for accessing the relay server 30 through the public telecommunication network 20, and the next three digits 301 are an identification number for identifying the public telecommunication network 20 operator. The next digits are the URL of a preset web site (eg, www.yahoo.com).

In this manner, the mapping table 32 corresponds to a predetermined digit number and the URL of the web site. An example thereof is shown in FIG. Although the mapping table 32 of FIG. 4 shows that all numbers input by the client are stored, the first three digits may be omitted since the first three digits are UMS identification numbers.

When the client inputs the shortcut number configured as described above, the shortcut number is transmitted to the relay server 30 through the mobile communication network 10 and the public communication network 20, and then via the UMS server 31 of the relay server 30. The corresponding URL is retrieved from the mapping table 32 and the search result (URL) is transmitted to the swap push server 33.

The swap push server 33 transmits the URL searched by the method as described above to the client-side terminal through the mobile communication network 10 in the form of a push push. The swap push service in this embodiment is described as using a short message service (SMS) as a bearer, but of course, the SMS may not be used as a bearer.

When using SMS, data transmitted to the client side can be configured as follows. That is, the parameter included in the SMS specifies the destination terminal number, the service ID, the message, the delimiter, and the callback URL to notify the swap alert by the swap push service in the service ID. You can perform a push-push service using SMS by indicating "press the call button to access yahoo.com" and using a delimiter followed by a callback URL (e.g. http://www.yahoo.com). .

An embodiment of a wireless Internet access method performed under the system configuration as described above will be described with reference to the flowchart of FIG. 5.

Referring to FIG. 5, first, a client presses a predetermined shortcut number through a keypad of a wireless mobile communication terminal to access a mobile communication network 10 (S100), and successively relay server 30 through a public communication network 20. (S110). Here, the connection to the relay server 30 through the mobile communication network 10 and the public communication network 20 is made by the first identification number "030" of the shortcut number input by the client as described above. That is, the client 10 transmits the preset identification number so that the mobile communication network 10 transmits the call to the public communication network 20 and processes the call back to the relay server 30 at the exchange of the public communication network operator in the public communication network 20. Will be.

Next, the UMS server 31 of the relay server 30 receives the caller identification number of the connected client and the speed dial number input by the client and transfers the speed dial number to the mapping table 32 (S120).

The mapping table 32 searches for the URL corresponding to the shortcut number input by the client (S130). As a result of the search, if the corresponding URL is not searched, a signal indicating that it has not been searched and a caller identification number are transmitted to the swap push server 33, and the swap push server 33 transmits an error message to the client (S140). When the corresponding URL is found as a result of the search, the URL and the caller identification number are transmitted to the swap push server 33 (S150).

The swap push server 33 transmits the URL received from the mapping table 32 to the received caller identification number by the swap push method using SMS (S160). The swap push method using SMS is as described above.

By this method, the client receives the URL of the website corresponding to the shortcut number entered by the client, and an SMS message is displayed on the client terminal, for example, "When the call button is pressed, the user connects to www.yahoo.com". Is displayed and the client presses the call button to access the corresponding web site (content server 50 shown in FIG. 1) through the mobile communication network 10 and the swap gateway 40 (S170).

6 is another configuration diagram of the relay server 30 for implementing another embodiment of the wireless Internet access system according to the present invention.

The relay server 30 of FIG. 6 is provided with an ARS server 34 and an exchanger 35 together with the UMS server 31 of FIG. 2 to guide the URL by voice. The ARS server 34 is a server for providing a voice answering service to the client side, and the switch 35 is connected to the ARS server 34 and the mobile communication network 10 to connect the ARS server 34 and the client side terminal. Connect it.

In the embodiment of FIG. 6, the ARS server 34 guides the URL to the client by voice, thereby reducing the number of digits of the shortcut number to be input by the client.

Various modifications are possible to this, but two types can be considered. First, by minimizing the speed dial number entered by the client, enter only the UMS identification number (030 in FIG. 3) and the public identification number (3019 in FIG. 3) of the public telecommunication network 20, and enter URLs of all websites registered in the mapping table. Voice guidance can be made.

The second method can be considered as a method of inputting a UMS identification number, a public identification number of the telecommunications network 20 operator, and a top-level URL of a web site, and prompting the subdirectory for a voice. In either case, only the number of digits in the mapping table 32 and the number of digits input by the client need to be changed accordingly. However, the configuration of the mapping table 32 is different from that of FIG.

FIG. 7 shows an example of the configuration of the mapping table 32 in the embodiment of FIG. 6. The mapping table 32 of FIG. 7 relates to the second method, and stores the shortcut number for the lower directory with respect to the top-level URL. That is, when the client inputs the top-level URL of the web site to which the client wants to connect, the mapping table 32 searches for the shortcut number of the subdirectory belonging to the top-level URL and the corresponding URL. The mapping table may be configured in a similar manner to the first method described above.

Another embodiment of a method for accessing a wireless Internet performed under the configuration as shown in FIG. 6 will be described with reference to the flowchart of FIG. 8.

First, step S200 to step S240 are performed in the same manner as step S130 in step S100 of the flowchart of FIG. 5. If in step S230 the URL is searched in the mapping table 32 and the search result does not come out, an error message is transmitted in step S240, but the error message at this time is transmitted to the voice by the ARS server 34, or FIG. As in 5, it can be delivered in the form of SMS.

When the search result is found, the searched URL, the shortcut number of the subdirectory of the URL, the URL, and the caller identification number are transmitted to the ARS server 34 (S250).

When the ARS server 34 receives the URL, the shortcut number, and the caller identification number, the ARS server 34 connects to the client-side terminal through the exchange 35 to guide the lower URL and the shortcut number by voice (S260).

When the client listens to the voice prompt and inputs a shortcut number of the desired lower URL (S270), the ARS server 34 transmits the URL and the caller identification number to the swap push server 33, and the swap push server 33 displays the above figure. Step S160 of 5 transmits the URL to the client side in the same manner as described below, and the client presses a button such as a call to access the content server.

9 is a block diagram of a wireless Internet access system according to another embodiment of the present invention. Compared with FIG. 1, the system of FIG. 9 is different in that it is connected by an arrow between the swap gateway 40 and the relay server 30 and the other points are the same.

In the system as shown in FIG. 9, when a client wants to access a desired content server 50 through a callback of a swap push message transmitted from the relay server 30, the relay server (via a swap gateway 40) 30, the correct full URL of the content server 50 is obtained from the relay server 30, and the content server 50 is accessed through the swap gateway 40. Such a system solves the problem caused by the capacity limitation of the swap push message. This is because if the URL has a plurality of sub-directories, a full push URL may not be delivered at a time using the conventional push push using SMS. Therefore, the system of FIG. 9 transmits the compressed URL when the URL is transmitted from the relay server 30 to the client side, and makes a connection to the relay server 30 when a callback is received from the client. The connection to the content server 50 through the gateway 40. Except for this point, all the methods described in FIGS. 1 to 8 may be combined as they are.

According to the present invention, since the wireless Internet service can be provided through the public communication network (PSTN) without passing through the wireless mobile service provider side, the content server does not need to be dependent on the mobile communication service provider side to provide independent services. Can be.

In addition, since it does not have to pass through the wireless mobile service provider side, it is easier to use than the conventional service and its cost is also low.

In addition, since the web site can be accessed through the shortcut number, the user can easily access the desired site without inputting the URL of the desired site through the keypad of the terminal.
