<First Embodiment>

In order to access the CP site, the terminal uses an IP address and a port number or accesses through a WAP gateway. Accordingly, the first embodiment proposes a job notification method using the IP address and the port number.

1 is a diagram showing the structure of a communication system for providing content to a content subscriber according to a preferred embodiment of the present invention.

Referring to FIG. 1, a system for providing contents to subscribers includes a mobile communication terminal 110, a mobile communication network 120, a wireless base station 130, and a mobile communication switching center 140. It includes a data communication network 150, DNS server 160, CP (170), work management site and server 180. The mobile communication terminal 110 is wirelessly connected to the mobile communication network 120 to provide a voice call function for performing a normal voice call by wireless communication with another mobile communication terminal or a wired telephone, and the mobile communication network 120 Access to the CP (170) by using a wireless data service or a wireless Internet service provided to receive the content.

The mobile communication network 120 includes a wireless base station 130 and a mobile switching center (MSC) 140. The mobile communication network 120 is wirelessly connected to the mobile communication terminal 110 to provide a voice communication service. And various functions for performing a mobile communication service such as a wireless data service or a wireless Internet service. Here, the wireless base station 130 performs a location registration function, a function of allocating a wireless channel, various functions required for radio call processing such as handoff, and the like. Perform additional service processing, incoming and outgoing call processing of subscriber, location registration and handoff procedure, interworking function with other network.

The data communication network 150 includes a DNS server 160, a CP 170, a work management site, and a server 180. The data communication network 150 performs data communication using the Internet on a mobile communication system. It performs virtual private network (VPN) access service, Simple IP and Mobile IP service, and Point-to-Point Protocol (PPP) authentication.

The DNS server 160 checks an IP corresponding to a CP name requested by the mobile communication terminal 110 to access a specific CP, and allows the specific CP site and the mobile communication terminal 100 to be connected through the IP. . CP 170 is a site that provides the stored content to the mobile communication terminal 110, there are a plurality of CPs according to the CP provider or content, each CP has a unique IP to access through the mobile communication terminal 110 Can be.

The work management site and the server 180 receive a work execution request from the CP 170 and request the work to the DNS server 160, and at the work site, an IP address of each CP and a work server IP at the time of work are performed. It can register work contents and working hours, and manages the table by randomly generating a port number for distinguishing CP operators while managing the information registered by CP operators in CP operator's work management table. The work management server manages matters registered in the work management site, and when the work start time of a specific CP, the DNS server 160 delivers a work IP address and a port number for distinguishing the CP service provider. In addition, at the end of the job, it notifies that the job is completed, and transmits the job IP address to the DNS server 160. At this time, in order to indicate the start time and the end time, it may be transferred to the DNS server 160 using a job start message or a job end message.

FIG. 2 is a diagram illustrating an operation procedure for notifying that a content site is being checked according to the first preferred embodiment of the present invention.

Referring to FIG. 2, in step 210, a work management site is created, so that a CP operator can register a work server IP, work contents, and work time at the time of work in the work management site. The work management site manages the table by randomly generating a port number for distinguishing the CP operators while managing the information registered by the CP operators in the CP management task management table.

When the job is registered as described above, the job management server manages it, and when the job start time arrives at step 220, the process proceeds to step 230 and the job server delivers the job IP address and the port number for the CP operator division previously created to the DNS server. . DNS server saves it and when DNS query is requested to the relevant server IP, it transmits port number for work management server IP and CP service provider as response of query. Thereafter, in step 240, the mobile subscriber station attempts initial access to a working CP operator site.

In this case, in step 250, the CP operator site in operation is initially connected to the work management server, and the work management server looks at the port number requested by the terminal and matches the work number with the port number in the work management table that it manages. Find and display the work in detail to the terminal. This can help users use their resources efficiently by providing users with accurate job notifications, increasing user convenience, and preventing unnecessary call connections.

3 is a flowchart illustrating an operation procedure for terminating the inspection notification of the content site according to the first embodiment of the present invention.

Referring to FIG. 3, in step 310, the job management server informs the DNS server that the job is finished, including the job server IP, when the job is finished. In step 320, the DNS server recognizes that the job is finished at the corresponding IP. When accessing subscriber station, normal call address is assigned by assigning normal IP address without assigning work management server address.

In addition, when the CP operators terminate the work earlier than the job end time, by sending a job end message to the job management server to inform the DNS server, including the job server IP that the job is completed, the job management IP, The call should be immediately processed normally.

Alternatively, there may be a scheme that periodically informs the DNS server of the work IP in order to prevent continuous access to the work management server, in which case the work management server to the DNS server will run every three minutes. Suppose you set up your work configuration IP, and your DNS server needs to automatically route your work configuration IP after six minutes of no reset.

Second Embodiment

In the second embodiment, it is to present a task notification method when the terminal accesses to the CP site via a WAP gateway (hereinafter referred to as GW).

WAP is a standard designed to provide a wireless Internet service in a current mobile communication network, and is a communication protocol standard used for electronic mail or Internet access in a mobile communication terminal.

Currently, there are 1.3 and 2.0 WAP standards used in the terminal. Since 2001, WAP 2.0 has been mainly used. Each difference is shown in Table 1 below.

Item WAP 1.3 WAP 2.0 Characteristic -9.6 Kbps transfer rate -WML (Wireless Makeup Language) language -144Kkbps.2Mbps (EVDO) transfer rate -Using Hyper Text Makeup Language (HTML) language contents -Text based configuration -Composed of graphic based content protocol -Use WAP protocol the -http protocol

WAP 1.3 uses a WAP GW because it has a separate WAP protocol and needs to be converted to WML. In addition, WAP 2.0 supports HyperText Transport Protocol (HTTP) to provide the same level of wireless Internet service as wired lines, and WAP GW is used to deliver HTTP messages between terminals and servers.

4 is a diagram illustrating a WAP gateway processing procedure.

The terminal 410 uses WAP 1.3 or WAP 2.0, and the WAP GW 420 supports both WAP 1.3 and WAP 2.0 because the WAP GW 420 must provide a different method according to the WAP standard of the terminal for transmitting various request messages. . Specifically, if the WAP GW 420 receives a WAP standard request message from a terminal using WAP 1.3, converts the protocol from WAP to HTTP, and receives a request message from a terminal using WAP 2.0, this is an HTTP format. Since it is, and performs a function to deliver the request message to the server (430). When the server 430 receives a Uniform Resource Locator (URL) request in HTTP format from the WAP GW 420, the server 430 transmits the content corresponding to the URL to the WAP GW 420.

5 is a diagram illustrating a work notification procedure of a wireless Internet service according to a second embodiment of the present invention.

Referring to FIG. 5, the CP site transmits site work related information to the work management server 535, and the work management server 535 transmits the work target IP to the work management server in step 540 to perform the work of the CP site. When the setup request message to the IP is transmitted to the server side DNS 530, the server side DNS 530 sets the job server IP as the job management server IP. In addition, the work management server 535 periodically sets the work target IP in the server-side DNS 530 in step 545 to prevent the long-time bypass prevention, and the server-side DNS 530 does not have a periodic reset, that is, specifically If there is no reset for 5 minutes, the routine is restored and the initial screen is connected to the CP provider's original site.

Thereafter, in step 550, the Internet access button in the terminal 505 is pressed to access a packet switched data network (PSN) 510. In step 552, the terminal 505 is connected to the PSDN 510. Get a DNS IP response. In step 554, the terminal 505 requests the proxy address to the terminal DNS 520 (for example, WAP1.3: wgw.nate.com, WAP2.0: ngb.nate.com), and in step 556, the terminal 505 receives a proxy address response (wgw.nate.com:203.236.43.xx, ngb.nate.com:203.236.43.xx) from the terminal side DNS 520.

The terminal 505 requests a connection to the WAP G / W 525 using the proxy address received in step 558, and receives an Ack from the WAP G / W 525 in step 560. In step 562, if the terminal 505 requests the initial page as the URL to the WAP G / W 525, the WAP G / W 525 queries the server-side DNS 530 for the URL IP in step 564.

In this case, the server-side DNS 530 sets the work management server IP to the WAP G / W 525 in step 566 since the CP site to which the terminal 505 is connected to is set as the work management server IP in steps 540 and 545. To pass. In step 568, since the initial page is requested by the IP received from the WAP G / W 525, the initial page is requested to the work management server 535. The work management server 535 responds to the initial page to the WAP G / W 525 in step 570, the WAP G / W 525 to the terminal 505, such as the reason for the work or working time on the initial page Announce the work history.

After completing all the work in the CP site, the CP site delivers a job end message to the work management server 535, and the work management server 535 to the server side DNS 530 release request message of the work target IP By sending it back to its original page.

As described above, the present invention notifies the subscribers that the CP operator subscribes to the content service during CP work, and that the site is being checked when the subscriber accesses the site.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

In the present invention operating as described in detail above, the effects obtained by the representative ones of the disclosed inventions will be briefly described as follows.

The present invention helps to efficiently use mobile telephone exchange resources by increasing the ease of use and preventing unnecessary call access while providing accurate work notifications to content subscribers by notifying that the subscribers are checking the sites connected to the content subscribers. Becomes

In addition, since the number of reconnections and the number of connection failures are reduced without recognizing that the content subscribers are checking the site, it is possible to prevent a sudden drop in the system call success rate due to the reconnection of the content subscribers with the site.
