It relates to a service search method.

The information service retrieval method is performed by the Guidance Subsystem (GDS), which is a part of the communication processing system, and provides a call transfer function that automatically connects to the selected information service through various retrieval methods.

Recently, the use of information services has been rapidly increasing due to the expansion of computers and terminals. Accordingly, information services have been diversified and specialized.

However, the conventional information service is provided through a packet decomposition assembly (PAD) that simply connects the telephone network (PSTN) and the packet communication network.

Therefore, there is a problem that the guidance function and information classification system for information service contents are weak and cannot provide various search methods.

In addition, the search form of the information service provided in the conventional packet decomposition assembly is simply a search by a menu list.

Therefore, as the number of information providers increases, the search time becomes longer and it is difficult to select a desired final information service because it cannot provide detailed information such as fee information and registration information.

In addition, in the conventional guide function system, in order to access the selected information service, the user is inconvenient to request a direct call connection.

Accordingly, there is a need for an information guide apparatus that provides various search methods for information service contents provided in a packet communication network to shorten a search time and provide a function for accessing a selected information service.

Accordingly, the present invention devised to solve the above problems provides a guide screen for information service contents and various search methods to shorten the search time and provide an information guide function for accessing the selected information service. An object of the present invention is to provide an information service retrieval method in a communication processing system that can use an information service.

Communication processing system is a service interlocking device developed to connect users of telephone network and information provider of packet communication network (HINET-P). It provides functions such as protocol conversion, speed conversion and media conversion in service access device. The function is provided by the information guide device.

The present invention provides a guide function for systematically collecting and arranging information service contents to information users of a communication processing system to compare and select each other through various search methods. In addition, the search function provides a guide function to compare and select each other. In addition, it provides a function to transmit necessary information to the service access device in X.29 format so that it can be directly connected to the selected information service through the search method.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a communication processing system service network to which the present invention is applied. The communication processing system that provides the information retrieval service is largely divided into the function of serving as a gateway between the telephone network switch and the packet network switch and the function of smoothly performing it.

When the information user 11 wants to search for the information service and the input is started from the telephone network 12, the service access device 13 (ISAP: Information Service Access Point) that connects the users of the telephone network connection to the packet network operates to make a smooth call. The connection function will be performed. After the call connection is made, the information users can select and access the information service of the information provider 17, and can be connected through the information guide device 14 (GDS: GuiDance System).

With the development of communication processing system, the information demand level of information users is improved, and as a result, the information provided by information providers is diversified and the emergence of new information services is accelerating. Therefore, smooth information retrieval without guide information is expected to be increasingly difficult.

The regional management device 15 (M-OAM: Mediation-Operation, Administration and Maintenance) that manages the service access device performs a billing management function, a user management function, a configuration management function, and the like.

2 is a configuration diagram of an information guide apparatus to which the present invention is applied.

The information guide device is connected to and connected to the information guide device providing a connection and communication function 24, a guide screen providing a guide screen and a search method providing and retrieval method processing unit 25, a statistical processing unit 26 for managing statistical data And a database (DB) manager 27 for managing the database and an information guide device (GDS) database 28 composed of guide information and screen information data.

When an information user requests a connection to an information guide device to obtain information on various information services, the ISAP 21 requests a connection through the X and 25 networks 22. The information guide apparatus calls the information guide apparatus connection and communication processing unit 25 when a hand signal is detected on the X.25 board. The information guide apparatus connection and communication processor 24 receives the hand signal and connects it to the guide screen providing and retrieving method processing unit 25. The guide screen providing and retrieving method processing unit 25 provides the guide information to the user from this time.

3 is a search flowchart of an information guide apparatus according to the present invention.

When the user requests a call connection (31), the DGS is connected to connect the call (32), the information provider is searched (33) after transmitting data for automatic connection (34), and the information service is connected to provide information. (35) The service connection is released (36).

4 is a detailed flowchart of the GDS connection establishment step according to the present invention. The start of the present searching method begins with the information user requesting a call connection from the ISAP 21 to the information guide apparatus 29. FIG. When the ISAP 21 sets up an X.25 (22) call and requests a call connection to the information guide device 29 (41), the X.25 board 23 of the information guide device 29 receives a hand signal ( 42. Fork and execute the connection and communication processing unit 24. FIG. The executed connection and communication processing unit 24 receives the received call to complete the call connection and informs ISAP 21 of this (43). When the call connection to the information guide device 29 is completed, the X.23 parameter is set using X and 29 to adjust the user screen interface (I / F) (44). When the screen adjustment is completed, an initial screen is provided (45).

5 is a detailed flowchart of an IP search step according to a search method according to the present invention.

When a call is connected by the GDS connection establishment step, a search screen is provided together with an initial screen (51). The user of the information guide device selects one of five search methods (52) to select an information service of a desired field. If a field or content is specified, a list of information providers (IP) related to the field is output (53), and the user selects the desired information provider (54) from the information provider list. The detailed information of the finally selected information provider is output (55) to confirm the user's connection request (56). When the user requests a connection, the process proceeds to the connection data transmission step for automatic access to the information service. If you do not request a connection request, you can reprint the list of providers to choose from.

6 is a detailed flowchart of a connection data transmission step for automatically accessing an information service according to the present invention.

First, an X.25 control call is generated to distinguish the data call from the access call. Control call generation sets the Q-bit of the header to 1 for use with X.29 (61) and makes the first byte of data the hexadecimal value ff (0xff) (62). In other words, by setting Q-bit to 1, the first byte of the data field is used as Oxff to inform the service interface that it is not normal data and to call the call for automatic connection. It then inserts the access information for the information provider (see Figure 9) into the data field (63) and sends an X.25 call to the service access device.

7 is a detailed flowchart of the information service access step according to the present invention. If you receive an auto-connection call, check the Q-bit and check 0xff. If this is checked then the IP address is identified (71). The user call connected to the information guide device is cut (72). Then call proceeds to the information service (73). As described above, the information guiding method is performed through the procedures of FIGS. 3 to 7.

8 is a block diagram of a search method for an information guide apparatus according to the present invention. Although the search function of the conventional guide information system is simple and provides a menu search method, the information guide device provides five various search methods so that a user can easily search for desired information. In the search method based on menu classification (81), 18 categories were classified by information service sector, and a menu system was established in the form of a middle category and a small category under the field.

In the search method (82) by the service name, it is possible to search by information provider name or abbreviation code. In the search method (83) by sector abbreviation, the information service can be searched by the fields classified in the menu system. As the information service increases and the menu system becomes huge, the search method by menu classification takes a lot of time to select the desired information service, and the search time can be reduced by using the search method by the abbreviation for each field.

The new information provider retrieval method 84 provides information about the newly registered information provider within a period of time (eg 1 month). The product code retrieval method 85 is a method of determining and retrieving a standard information classification code with a communication processing system of an information provider. The product code retrieval method enables direct access to a desired information service.

9 is a block diagram of transmission data for an information service access request according to the present invention.

Since the information guidance device is connected to ISAP through X.25 communication network, X.25 communication protocol is used for communication. In the conventional information guidance system, the call connection change request cannot be made during X.25 communication. However, in the communication processing system, protocols are defined in ISAP and the information guidance device so that the call connection change request can be made using X.29 instructions. It was.

When the information user selects the desired information service using the information guide device, the information guide device sets the Q-bit to 1 in the connection and communication block for X.29 communication and requests the information service connection (X.25 from ISAP point of view). In order to request call connection change during communication, the following data is transmitted. First, the first byte of data uses an auto-connect flag (91) of 0xff in hexadecimal, the information provider address (92) the information service name (93) and the product code name (for product code access). 94). ISAP receives a request for access to the information service and connects the information user to the information provider address.

As described above, the present invention can be applied to an information guide method for providing various search methods in a system for guiding information services provided through a communication processing system, and can also be applied to an information search system for providing an access function together with a search method. Can be.

As described above, the present invention can shorten the search time and the access time, and can be applied to almost all computer systems by being implemented as a general UNIX computer without special hardware (H / W) configuration.
