PURPOSE:To prevent massage information from being changed or deleted by a person except a registrar by adding the identifying information of a caller to the message information when the message information is registered, changed and deleted to a center unit. CONSTITUTION:When the message information registered to a center unit is changed, a terminal equipment reads the telephone number of its own equipment from a memory part, the telephone number is added to the head part of the message information, and changing message information name and the control information instructing a change are added and sent to a line. The control circuit 36 of the center unit separates the message information, the telephone number of a caller and control information from transmission information and stores temporarily them to buffer circuits 32-34 respectively. In is decided from the control information whether the purpose of the transmission information arrival is for registering and drawing or for changing and deleting or not, and the control for it is executed.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Object of the Invention] (Industrial Field of Application) The present invention provides information such as guides, advertisements, telephone directories, etc. Regarding the information supply method provided to the public.

(Prior Art) In recent years, various information network systems have been developed. Among them, for example, as shown in FIG. , or as shown in FIG. 6, connects to the center device 3 via the digital line 2 and switching network 4, and sends message information such as guidance, advertisements, and telephone directories sent from callers of each terminal device to the center device 3. When there is a request for supply of desired message information from an unspecified terminal device 1 in this state, the center device 3 searches for the corresponding message information and sends it to the calling terminal. There is something that I tried to do. If such a system is used, the subscriber of the terminal device 1 can easily obtain desired message information at any time, which is extremely convenient.

However, in the conventional information supply method used in this type of system, the message information sent from each terminal 1aii is registered by simply adding its title. If someone attempts to change or delete any message information, they can do so without any restrictions, just as they would obtain the message information, so there is no risk that the message information will be changed or deleted by someone other than the registrant. there were.

(Problems to be Solved by the Invention) As mentioned above, the conventional system has extremely unfavorable problems in terms of information management. While maintaining the freedom to retrieve information, it is intended to provide an information supply method that allows only registrants to change or delete message information, thereby ensuring the reliable management of registered message information. It is.

[Configuration of the Invention (Means for Solving Problems)] The present invention provides a method for transmitting message information by adding caller identification information to the message information when registering message information in a center device in a terminal device; When the message information registered in the center device is changed or deleted, the calling party's identification information is sent together with control information to that effect, and the center device is provided with an identification information verification means, and by this verification means, When control information to change or delete desired message information arrives from a terminal device, the caller's identification information sent at the same time is checked against the identification information added to the desired message information, and this verification is performed. The desired message information is changed or deleted only when it is determined that the two pieces of identification information match.

(Operation) As a result, even if a request to change or delete message information comes from someone other than the registrant, in this case, the identification information does not match that of the registrant, so the center device will not be able to change or delete the message information. No erasure occurs and the message information is definitely retained. Further, since identification information is checked only when changing or deleting message information, if an unspecified subscriber wants to retrieve message information, there are no answer restrictions and the message information can be obtained freely.

(Embodiment) A terminal device to which the information supply system according to one embodiment of the present invention is applied is, for example, a multi-function telephone, and is equipped with message information transmission means and reception display means in addition to normal communication means. . Among these, the message information transmitting means generates the telephone number of the own device as the calling party's identification information (ID) when changing or deleting the message information registered in the center device, and transmits this telephone number to the third party. As shown in the figure, it is added to the head 21 of the message information insertion section 20 and sent. Incidentally, when transmitting this transmission information, the message information transmitting means transmits control information representing the content of the transmission request, that is, registration, withdrawal, change, or deletion, together with information representing the title of the message information.

On the other hand, the receiving system of the center device is constructed as shown in FIG. That is, this receiving system includes a receiving circuit 31 that receives transmitted information from a terminal device introduced through an exchange circuit (not shown), and a receiving circuit 31 that receives message information, a telephone number as identification information, and a telephone number as identification information from the transmitted information received by this receiving circuit 31. three buffer circuits 32, 33, and 34 that separate and temporarily store control information; a storage section 35 that stores message information and registrant's telephone numbers in association with each other;
It has a control circuit 36. Among these, the control circuit 36
As a control means for changing or erasing message information, for example, as shown in FIG.
and a change/deletion control means 36b. First, when 1lIlIl information instructing to change or delete arbitrary message information arrives from the terminal device, the identification information collation means 36a stores the identification information (telephone number) that arrived at the same time in the storage section 35, and stores the above-mentioned arbitrary message information. The information is registered and compared with the identification information added to the ID.

On the other hand, the change/deletion control means 36b changes or erases the designated message information when the identification information collation means 36a determines that both pieces of identification information match.

Next, the information supply system of this embodiment will be explained based on the above configuration. For example, when attempting to change the message information registered in the center device, the subscriber of the terminal device inputs the new message information, specifies the name of the message information to be changed, and then presses the function button and send button to instruct the message change. Manipulate. Then, the terminal device first reads its own phone number from the storage unit, adds this phone number to the head of the message information, adds the name of the message information to be changed, and control information instructing the change, and connects the phone number to the line. Send.

On the other hand, the control circuit 36 of the center device sometimes monitors the arrival of transmission information from the terminal device in step 4a as shown in FIG. The message information, caller's telephone number and control information are separated from the transmission information and temporarily stored in buffer circuits 32, 33 and 34, respectively.

Then, in steps 4C and 4e, it is determined from the control information stored in the buffing circuit 34 whether the purpose of the arrival of the transmitted information is registration/withdrawal or change/deletion, and in the case of registration/withdrawal, the process starts from step 4C. The process moves to step 4d, where control for registering or retrieving message information is executed.

Now, assuming that the control information that has just arrived from the terminal device instructs a change, the control circuit 36 performs step 4.
The process moves from step 4e to step 4f, where the telephone number of the caller registered as added to the corresponding message information is read out from the storage section 35, and in step 4g, this telephone number and the buffing circuit 33 are temporarily stored. Compare and match the stored phone number of the caller. And step 4h
From this comparison result, it is determined whether or not the Ameyukiwa numbers match, and if they match, it is determined that the caller who is about to make the change is the caller who registered the message information. Then, the process moves to step 4j, and in this step 4j, the corresponding message information is changed. Incidentally, if the caller's instruction is to delete, the corresponding message information stored in the storage section 35 is deleted. On the other hand, if it is determined in step 4h that the Ameyukiwa numbers do not match, it is determined that the caller who instructed the change is not the caller who registered, and the process proceeds to step 41. Then, the corresponding message information is stored as is in the storage section 35.

As described above, in this embodiment, when message information is registered in the center device, the phone number of the terminal device is added and registered, and when the message information is changed or deleted, the terminal device is sent from the terminal device to the center device. A telephone number is sent, the center device compares this telephone number with the registered telephone number, and only when the two numbers match, the corresponding message information is changed or deleted. The original message information is not changed or deleted by anyone other than the registrant, so that the message information can be securely retained. Further, since telephone number verification is performed only when changing or deleting message information, any subscriber can easily retrieve message information without being subject to any response restrictions.

Note that the present invention is not limited to the above embodiments. For example, the identification information may be anything other than a telephone number, with a password input by the subscriber added to the telephone number; in short, any information may be used as long as it is used uniformly for each caller.

In the above embodiment, the terminal device generates its own telephone number and automatically adds it to add identification information to the message information. It may also be added by inputting the information. In this way, a calling party who has registered arbitrary message information can change or delete message information not only from his own terminal device but also from other terminal devices. Roughly speaking, in the embodiment described above, when there is a request to retrieve message information, only the message information is sent to the terminal device, but the message information is now sent with the identification information of the registrant added. Good too. In this way, when a large number of similar message information are registered, the terminal device can easily determine whether the message information is registered by itself, and thereby change or delete the message information. In this case, the message information registered by the user can be specified accurately at one time without having to re-specify it many times, thereby improving the operability of the valve. As a further example of its development, the terminal device is provided with a means for comparing the identification information sent from the center device with the identification information added to the message information and its own identification information, and only when it is determined by this means that the re-identification information matches,
A key for instructing change or deletion may be operable. As a result, it is possible to prevent input of instructions to change or delete message information registered by a terminal device other than the own device, in other words, to prevent erroneous operations from being performed, further improving operability. can be increased. In addition, the gist of the present invention also covers the type and configuration of the terminal device, the configuration of the center device, the control procedure and control content of the control circuit, the type of message information (not only character code information but also image information), transmission method, etc. Various modifications can be made without departing from the above.

[Effects of the Invention] As described in detail above, according to the present invention, in a terminal device, when message information is registered in a center device, calling party identification information is added to the message information and transmitted, and the message information is transmitted to the center device. When changing or deleting the message information registered in the terminal, the calling party's identification information is sent together with control information to that effect.On the other hand, the center equipment is provided with identification information verification means, and this verification means allows the terminal equipment to When control information to change or delete the desired message information arrives from the source, the caller's identification information sent at the same time is checked against the identification information added to the desired message information, and the result of this checking is performed. By changing or erasing the desired message information only when it is determined that the two pieces of identification information match, it is possible to change or delete the message information while maintaining the flexibility of message information withdrawal by unspecified subscribers. Deletion can only be performed by registrants,
This makes it possible to provide an information supply system that can reliably manage registered message information.
