First, the user accesses the corresponding site through the wireless Internet using his mobile communication terminal 110 (S410). This connection can be made by the user inputting the address of the corresponding site such as a Uniform Resource Locator (URL) into the mobile communication terminal 110 or selecting an access menu provided by the mobile communication service provider. ) And the real-time call service server 410 is established.

If the site provided by the real-time call service server 410 is a site providing services only to subscribers, a subscription procedure is performed (S420).

One preferred embodiment of performing the sign-up process is that the real-time call service server 410 provides a log-in screen to the mobile communication terminal 110 so that a user who accesses the user enters an identification number (ID) and a password. To log in.

If the user is not subscribed (S421), the real-time call service server 410 provides the mobile communication terminal 110 with the necessary items for subscription, and allows the user to input the necessary information for the corresponding item (S422). ). Information required for registration may include an identification number (ID), a password, a name, an address, and the like, and a telephone number for a phone call is necessary. Of course, the registration procedure can be joined only when trying to use a service capable of real-time call service, but can also subscribe to the site through the wired Internet at any time. In other words, you can access the site by wire using a personal computer at home and subscribe. In this case, a separate subscription procedure (S420) is not necessary through the mobile communication terminal 110.

Now, the real time call service server 410 searches the database 420 and transmits the service items to the mobile communication terminal 110 (S430). In this case, it is preferable to provide the service items by dividing them by category so that the user can easily find the desired items.

As an example, the major categories include "Chat Room", "Flea Market", "Job Jobs", etc. The middle class of chat rooms is "Movie Room", "Music Room", "Leports Room", etc. The classification of "used cars", "home appliances", "furniture", etc. may be classified as "office jobs", "business", "technical jobs", etc.

The user who receives the service items delivered by the real-time call service server 410 searches for a category he / she wants from among the category items provided by the real-time call service server 410 using the mobile communication terminal 110 (S440).

The real-time call service server 410 provides a list and function items related to the final service item selected by the user to the mobile communication terminal 110 (S445). In this case, the functional item refers to an item that allows a user to edit the posted items of the corresponding site, such as opening a new item or deleting an existing item.

Now the user selects one of the functional items delivered by the real-time call service server 410 in step S445 (S450). Hereinafter, the functional items of "post posting", "call", "delete post, and" end of service "will be described as an example.

If the user selects "Posting Post" among the functional items in step S450, the procedure S461 to S463 allows the user to register a new item (post) on the site.
