Description

Directory service method using intelligent network

The present invention relates to a directory service method in which a user can be provided with a directory service, which is a telephone number guide service, online without the help of an operator using an intelligent network.

Today, as information networks grow in size and global information networks such as the Internet have been established, the number of information devices and subscribers connected to the network has increased so that all information related to subscriber information and information communication services has become complicated and vast. Therefore, there is an urgent need for a new guide service that enables users to conveniently and conveniently access information required for information communication services online by systematically and efficiently managing it. The directory service is an information guide service that makes it possible to easily retrieve the directory information in the network through a standardized interface without operator intervention by placing all the information necessary for the information communication service in the database and placing it in the network.

The status and problems of 114 information service, a representative directory service provided in Korea, are as follows.

In recent years, the use of 114 information service has soared every year, and the completion rate of calls has remained at about 50%. In terms of users, an average of 2.7 calls must be made to receive the information service. In addition, the number of phone calls is increasing every year, which is about 120 won per call, which is three times more expensive than the base rate of local pay phones.

If the user wants to use the telephone guide service, he / she will look for a phone book or rely on the 114 guide service. However, the telephone book can be updated once a year so that the information cannot be reflected immediately. It is inconvenient to do and lacks mobility. In addition, in the case of the 114 information service, the user cannot cope quickly with the change of subscriber information, and in this case, the user has no choice but to go hunting for information in a vast forest of information, and in the case of personally managed information, the user must manage it. Neglecting information alone can only rely on memory.

In order to receive the current telephone number guide service, the user dials 114 and inquires a telephone number, and the operator listens to the user by voice synthesis of the telephone number retrieved from the database of the 114 information system. In order to receive phone number service in other areas, you must first know the area code, find out the area code, and then dial 114 with the area code to receive the phone number service in that area.

In the case of receiving the telephone number guide service through the operator, the user needs to spend a lot of time to obtain the final information due to the low connection rate of only 50%. In particular, the frequent change of information connected to the telephone network results in the change of information. If you do not reflect this information immediately, considerable effort and time investment is required to find the desired telephone number. From a telecommunications operator's point of view, the number of explosive phone number service services is 3.18 million per day, which is 3.6 times that of Japan, which is 5 times per 100 subscribers. The number of human resources invested for this purpose is 4,100 people, and the cost burden is about 200 billion won every year. In the case of Korea Telecom, the deficit last year was 297 billion won.

The present invention has been made to solve the above problems, the operator of the operator using a text phone (an intelligent public telephone terminal capable of inputting letters, numbers, symbols and viewing the input and output results on the screen) connected to the service performing exchange Its purpose is to provide a directory service method that enables users to easily search online for desired directory information directly from a database built on a service control system and to receive a desired telephone number in real time.

11: service performing exchange

12: service control system

In order to achieve the above object, the present invention provides a directory service method applied to an intelligent network, wherein a service performing exchange receives a service identification code and a search key or an approximate search key from a user terminal and transmits a search request message to a service control system. The service control system recognizes a search request message and searches a database to compare whether there is information identical or similar to a search key input by a user; If there is no matched or similar subscriber information as a result of the comparison in the first step, a guidance message indicating that there is no corresponding information is transmitted to the service performing exchange, and if there is matched or similar information, the matched information is more than a predetermined number. A second step of determining cognition; A third step of extracting and transmitting the corresponding subscriber number to the service performing exchange when the number is less than a predetermined number as a result of the determination in the second step, and comparing the threshold number set by the service manager if the number is greater than or equal to the predetermined number; And as a result of the comparison in the third step, extracting the corresponding numbers if they are within a threshold range and transmitting them to the service performing exchange, and sending a retransmission request message requesting a proximity search key to the service performing exchange if above the threshold. A fourth step is included.

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

1 is a configuration diagram of an intelligent network to which the present invention is applied, in which 11 represents a service performing exchange and 12 represents a service control system.

The intelligent network processes a service by interaction between two kinds of intelligent network devices, a service switching point (SSP) 11 and a service control point (SCP) 12. When these devices are analyzed from a more functional point of view, they have a Call Control Function / Service Switching Function (CCF / SSF) and Service Control Logic that are responsible for the call exchange connection. Service Control Function (SCF), Service Data Function (SDF) of database function with subscriber information, and SRF (Special) that performs functions such as announcement, digit collection, voice synthesis / voice recognition, etc. Resource function). (The SRF function is a function element of an intelligent network and a function not directly related to the present invention, so the description is omitted in FIG. 1). In the present invention, the call control function / service switching function (CCF / SSF) is mounted on the service switchboard 11. The service control function SCF and the service data function SDF are mounted in the service control system 12.

Looking at the flow of information transmitted and received between intelligent network nodes, such as a user calling terminal, a service performing exchange 11 and a service control system 12 to provide a directory service.

First, a service user inputs a service identification code and a search key in text form to receive a directory service from a calling terminal (text phone). In this case, the search key refers to a telephone subscriber name, a public institution name, a business name, etc. subscribed to the corresponding phone number. If the exact subscriber name is not known, all similar subscribers can be searched using an Approximate Search key. The service performing exchange 11 receives the search key and requests a service to the service control system 12 through the common line (NO. 7) signal channel. From this point on, the control right for the service is in the service control function (SCF) of the service control system 12. The service data function (SDF) in the service control system 12 has a search key excluding the service identification code, searches for the corresponding information input by the subscriber and the subscriber information stored in the database, and extracts the corresponding telephone number if they match. The service performing exchange 11 transmits the service number to the user terminal and outputs the corresponding phone number on the screen of the text phone, and sends the number to the service performing exchange 11 when using the immediate call function. The call is requested by the Call Control Function (CCF) so that the call is established.

2 is a flowchart illustrating a directory service according to the present invention.

First, when the service performing exchange 11 receives a search key (or an approximate search key) together with a service identification code from a user terminal (text phone) (21) and transmits a search request message to the service control system 12 (22). The service control system 12 recognizes the search request message (23) and starts processing. The subscriber data function (SDF) searches the database (24) and compares (25) whether there is information matching the search key entered by the user. In the database constructed in the service control system 12, all subscriber information is sorted by name to provide directory services, and the subscriber data function (SDF) searches for all similar subscribers in a pattern matching method using an approximate search function. . If there is no matched subscriber data as a result of the search, a notification message is transmitted to the service performing exchange 11 informing that there is no corresponding information (26). If there is matched information, it is determined whether there is one matched information (27). If there is only one, the corresponding subscriber number is extracted and transmitted to the service performing exchange 11 (28), and if there is more than one, Compared with the threshold set by the service manager (29), if the number is within the threshold range, all the numbers are extracted and transmitted to the service performing exchange (11) (28), and when it is above the threshold, the search interval can be narrowed. A retransmission request message requesting a closer search key is sent (30) to the service performing exchange 11 and terminates.

Then, the user connects the call to the other party's number using an immediate call function, which can directly dial the received telephone number or directly connect the telephone number outputted from the search without re-entering.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention provides a database of subscriber information related to an information device (for example, a telephone, a fax, a mobile phone, a pager, etc.) connected to a public telecommunications network, and is located in an intelligent network so that a user can search using a search key anywhere on the move. This allows you to easily and easily provide the desired online subscriber information (a set of phone subscriber information categorized by service, occupation, and life) connected to the public telephone network without the assistance of the 114 operator. When inquiring the telephone subscriber information connected to the public telephone network using the database installed in the intelligent network, it is not through the operator. As a result, the processing time for the telephone number inquiries due to the sudden increase in usage and the processing rate for the inquiries are reduced. No discomfort from the back, and carelessness at the same time Even if the information is lost, it is possible to easily receive the telephone number guide service without depending on the memory of the individual.
