It constitutes 30.

The terminal 10 is a data input device (not shown) consisting of a plurality of keys so that the user can input data in letters and numbers, and the data processing device (not shown) and the data input from the data input device; It is provided with a screen output device (not shown) which operates by internal calculation means through a data processing device, executes and transmits the calculated data with an internal data transmission control program, and processes information data received from the outside and outputs them as text and images. One type of computer is provided with a terminal for handling data such as a computer or a personal computer, that is, a terminal for handling media such as audio, images, and data.

The network control circuit unit 11 is a short-range communication network that binds each communication network such as a building or a premises as a device to which a function of transmitting communication data call signal detection and selection signals and recovering and transmitting input error data is provided.

As shown in FIG. 2, when the user requests information collection of an external service, the communication relay unit 20 inputs and reads a signal output from the terminal 10 and reads whether the user is a registered subscriber. Check and connect to an external service on behalf of the user to generate and destroy the authentication proxy, which is the data of the authority to retrieve and provide information to the agency 22 to output.

The proxy unit 22 inputs the authentication proxy output from the connection unit 21 and requests and allocates the resource ID granted to the external service to the data distribution unit 23 of the output terminal and receives information on behalf of the user. Connect to request or collect.

The data distribution unit 23 generates and provides the resource ID requested by the agent 22, and controls the resource ID conversion of the output stage to securely collect the information data collected by accessing the external service to the output terminal. Connect to the department 24 to request.

The resource communication unit 24 converts the signal into an appropriate signal according to the resource ID conversion request of the data distribution unit 23 of the input terminal, outputs it to the resource conversion unit 26 of the output terminal, and sends the resource ID to the data distribution unit 23 connected to the other output terminal. It outputs a data signal notifying that the data has been converted and at the same time, it outputs the unconverted resource ID.

In addition, the resource control unit 24 connects the storage unit 25 to the output terminal to store a plurality of registered resource ID conversion.

The resource conversion unit 26 receives the resource ID conversion from the resource control unit 24 to connect to the service station to search for information and provide the retrieved information to the terminal 10 through the agent 22. Connect it so that

The present invention constituted as described above will be described in detail as follows.

The present invention relates to a communication relay device that can be used in conjunction with a plurality of external services, as shown in Figures 1 to 2 when the user requests access to the external service connection unit 21 of the communication relay unit 20 After checking whether there is extra authentication data and approving the access to the user, the agent 22 converts and allocates a new resource to the connected user, and outputs the information search signal desired by the user who has been granted the generated resource. The resource conversion unit 26 connects to the external service unit and transmits the information data to be retrieved from the agent unit 22.

Referring to Figure 3a.3b, 3c in more detail the operation and effect of the present invention, the terminal 10 operating by supplying the power supplied by the user is the user outputs a communication-related program and the user is associated with the communication When a command of an external service and a connection approval request are inputted on the program and outputted to the network controller 11, the network controller 11 converts the input communication call signal into communication data and outputs it to the communication relay unit 20, thereby connecting. It is possible to (S1).

The communication relay unit 20 inputs the connection approval request data output from the terminal unit 10 through the connection unit 21, and the extra authentication data among the authentication data allocated by the connection unit 21 from another user who wants to communicate. It will search for a presence.

If there is no extra authentication data in the connection unit 21, the connection unit 21 temporarily stores the connection approval request data inputted from the terminal 10 and waits until an extra authentication data is generated ( S2).

In addition, when the connection unit 21 reads the extra authentication data among the authentication data stored therein, it allocates and distributes an authentication proxy that allows the user to access and requests an access permission. The wait signal is output until it is secured (S3).

On the other hand, when the connection unit 21 assigns the authentication agent right to the agent unit 22, the agent unit 22 inputs the request data output from the terminal unit 10 to output data to other devices on behalf of the user. To be able.

At this time, the user converts the authentication proxy transmitted from the connection unit 21 to the appropriate signal through the network control unit 11 by using the terminal terminal 10 to check the connection approval message output to the screen output device, and then the data input device. By calling the desired external service station through the input of the classification and type of information data (S4).

The agent 22, which has been assigned the authentication authority, determines whether the data input from the terminal 10 is a predetermined command related to the information service and compares it with the data stored therein, which is input to the agent 22. If the data is not a designated instruction, the proxy unit 22 determines that the error data is an error signal and notifies the terminal 10 to generate an error signal, and requests the user to input the type and classification of the desired external service station or information data again. (S5).

On the other hand, if the command input by the user is a designated command, the proxy unit 22 determines whether the user requests an external service or an internal service, and if it is determined that the internal service request is made by the internal communication relay unit 20 stored therein. The related information of the manufacturer and billing and usage tips will be transmitted to the user (S6).

On the other hand, if the command input by the user is a command for requesting an external service, the proxy unit 22 may respond to the authentication from the user's connection request, but may not directly connect with an external service station, so that the user can access the external service. The data distribution unit 23 is requested to allocate an extra resource ID.

At this time, the data distribution unit 23 checks whether there is an extra resource ID stored therein according to the resource ID allocation request of the agent unit 22, and if there is no free resource ID, the agent unit 22 is the data distribution unit 23. It waits until it allocates a resource ID from (S7).

In addition, when the requested extra resource ID exists, the data distribution unit 23 allocates the extra resource ID to the agent 22 to allow the agent 22 to communicate with the external service station (S8).

On the other hand, the data distribution unit 23 allocates the resource ID to the agent 22, but the agent 22 retrieves the data because the resource ID alone may damage or lose data transmitted from external and internal conditions. Therefore, it is required to allocate the resource control unit 24 to the resource ID conversion is added that can correct the damaged and lost data.

The resource control unit 24 checks whether the signal inputted from the data distribution unit 23 is a resource ID conversion request, and if it is not a resource ID conversion request signal, an error has occurred when retrieving data from the data distribution unit 23. After the distribution 23 retrieves the data again, the resource ID conversion request can be made again (S9).

At this time, when the resource control unit 24 receives the resource ID conversion request from the data distribution unit 23, the resource control unit 24 converts the resource into a communicable resource according to a program stored therein, generates a resource ID conversion, and assigns it to the resource conversion unit 26. If the resource ID conversion approval is notified to the data distribution unit 23, but the resource ID conversion approval is not output by the resource retrieval unit 26 data search when the resource ID conversion is approved, the resource ID conversion is generated by re-converting the resource ID. After doing so, the data distribution unit 23 notifies the resource ID conversion approval (S10).

Meanwhile, the resource conversion unit 26 processes the command input by the user. At this time, the command input by the user selects an external service station and simultaneously moves to another external service station or is a command for communication connection between users. And to be connected to the service station 30 (S11).

In addition, the resource conversion unit 26 interprets the information retrieval command required by each external service station after connecting to the service unit 30 and resides in the information program (S12).

As soon as the resource conversion unit 26 resides in the information program, the external service station checks whether there is information data to be searched by the resource conversion unit 26, and then there is information data to be searched. At the same time, the information document image and audio data are transmitted.

At this time, if there is no information data confirmation notification from the external service station, the resource conversion unit 26 attempts communication connection with the external service station again after treating it as a communication failure and re-residents in the information program of the external service station to reinterpret the necessary command ( S13).

The resource conversion unit 26 resident in the information data of the external service station checks whether the information data transmission completion signal is input from the external service station while compressing and storing the information document image and audio data transmitted from the external service station in the internal memory immediately. If the transmission completion signal has not been input yet, the information data of the external service station is received until the transmission completion signal is transmitted (S14).

When the transmission completion signal is input from the external service station, the resource conversion unit 26 compresses and stores it in a safe place in the internal memory according to the type and classification of the received information data (S15).

Subsequently, the resource conversion unit 26 notifies the resource control unit 24 to terminate the connection with the connected external service station at the same time as notifying that all information data is transmitted from the external service station.

At this time, the resource control unit 24 returns the resource ID conversion allocated from the request of the resource conversion unit 26 to the data distribution unit 23 to be used by other users (S16).

On the other hand, the information data stored in the resource conversion unit 26 begins to output to the terminal 10 through the proxy unit 22 (S17).

Here, the agent 22 checks whether the user has stopped inputting the information data from the terminal 10 during the process of transmitting the information data transmitted from the resource conversion unit 26 to the terminal 10. When the information data input is not interrupted, the information data is transmitted until it is completely transmitted to the terminal 10 (S18).

In addition, when the user stops inputting the information data, the agent unit 22 returns the authentication agent right to the connection unit 21 so that the agent unit 22 no longer communicates with other servers in the communication relay unit 20. The communication relay unit 20 terminates the communication connection with the terminal device 10 by terminating the connection (S19).

According to the present invention, the communication relay unit is connected to communicate with a plurality of external service stations when the user requests information data retrieval, so that the user can freely move between the plurality of external service stations and receive desired information. At the same time, it is possible to extend the communication connection range by enabling communication connection between multiple users.
