Description

[Detailed description of the invention] [Industrial application field] The present invention is a system that provides an information search service.

In particular, the present invention relates to an access interruption/resumption method suitable for Videotex systems such as Captain.

[Prior Art] The Captain System uses a method for storing and registering arbitrary access points, as described on page 8 of ``Videotex Communication Network Service Interface (edited by Center)'' published by the Telecommunications Association of Japan. By storing the screen number of the image information according to the user's instructions, it is possible to return to that screen from any state.

However, this is valid only during - times of communication and becomes invalid when five lines are disconnected.

[Problems to be Solved by the Invention] The purpose of the present invention is to enable the user to continue searching from where he left off the next time he accesses the information, even if he interrupts an information search midway through and disconnects communication. By memorizing and registering, at any time during the communication,
- An object of the present invention is to provide an access interruption/resumption method that makes it possible to interrupt communication once and then return to the registered access point and perform a search the next time the access is made.

[Means for Solving the Problems] The above object is achieved by adding a storage medium corresponding to user information to a system that provides information services, and registering interruption information therein.

[Effect] By adding a storage medium that corresponds to the user to the system that provides information services, even if access is interrupted during a search, the information will be registered in the storage medium and will be saved the next time the user accesses it. access can be continued from the point of interruption.

Furthermore, by registering an arbitrary access point in the storage medium according to the user's instructions, it becomes possible to search from that access point the next time the user accesses the system.

[Embodiment] An embodiment of the present invention applied to a Videotex system will be described below with reference to FIG.

FIG. 1 is a schematic system block diagram, in which 1 is an information center that stores various information, 2 is a storage medium, and storage areas are allocated corresponding to each user's information. 3
Reference numeral 4 indicates a Videotex communication network that performs exchange processing, etc., and 4 indicates a user terminal, which searches and displays information stored in the information center.

FIG. 2 shows the search interruption sequence. When a user searches for information from a user terminal, the information center transmits the requested information to the terminal. Here, for example, information (5
), the user interrupts the search by -1, and
If the user attempts to continue the next communication, the user requests the center to store the information.

When the center receives a storage request, it registers the current search state in the storage area corresponding to the user information on the storage medium.

When the center completes the registration of information, it outputs a message to that effect to the terminal. When the user confirms that the information has been stored, the user requests termination of the communication.

Next, FIG. 3 shows a search restart sequence.

When the communication start process is completed, a continuation of the previous communication is requested by a memory read request. Upon receiving this, the center reads the search status from the storage area corresponding to the user, and thereby transmits the search information (5) to the terminal.

As a result of the above, even if the user ends communication on -1, it is possible for the user to continue the search from the previous communication in the first communication.

By the way, in the information center, information is stored in the form shown in FIG. 4, with each piece of information being associated with each other by a primary information access selector.

When searching for information on the Videotex system, it is common to select information starting from the first piece of information and following the instructions.

However, by using the present invention, if the desired information is registered in the storage area several times using the same procedure as shown in FIG. It is possible to obtain the desired information by reading the memory using the same procedure as shown in the figure.

Furthermore, even if registration information is stored in the storage area in FIG. 3 at this time, it is possible to search for other information using the normal selection procedure unless a storage read request is made.

[Effects of the Invention] According to the present invention, even if a search is interrupted midway, by calling up the interruption information registered in the storage medium, the next time communication is performed, the search can be continued from the point where the search was interrupted. You will be able to do this.

Further, by registering an arbitrary access point I- being searched for in the storage medium, the next time communication is performed, it becomes possible to search from the registered access point according to the user's selection.
