Intelligent network opening system for service and its method

The present invention relates to an intelligent network opening system and a method for a service provided in a device of an intelligent network service pusher.

In general, in a conventional intelligent network service, a call originated from a telephone terminal is delivered to a service exchange point, which is an intelligent network device, and a service request message transmitted from the service exchange point is transmitted in a service control point. The service logic controls the service and provides the service to the intelligent network service subscriber. In the next generation intelligent network, the intelligent network service created by the combination of service independent building blocks in the service creation environment is introduced to the service control system through the service management system to provide the service to the subscriber. .

1 is a general structural diagram of a conventional intelligent network. Referring to Figure 1 describes the general structure of a conventional intelligent network as follows.

The intelligent network service provides the intelligent network service to the subscriber by interworking with the intelligent network devices. A call originated from the calling party's telephone terminal 11 is transferred to the service switch 20 which is an intelligent network device. The service exchanger 20 sends a service request message to the service control system 30 in an intelligent network protocol message by receiving a request from the calling party 11 to use the intelligent network service. The service logic in the service control system 30 controls the service by referring to the profile of the intelligent network service subscriber stored in the form of a database 35 and retransmits the result to the service exchanger 20. The service exchanger 20 connects a call between the calling party 11 and the called party 12 with result data received from the service control system 30 or performs other additional services. The intelligent network device is provided by the network provider and the intelligent network service is operated by the intelligent network service operator. The service subscriber refers to a person who subscribes to a service of a network operator or a service manager who provides a service using an intelligent network device, and the intelligent network service subscriber may be a service user at the same time. In the next generation intelligent network, a service is generated by a combination of service independent blocks in the service development environment 60. The generated intelligent network service is introduced to the service control system 30 through the service management system 70 and provides a service to the subscriber. The introduction of the service development environment 60 enables the intelligent network service subscriber to create a desired service with the help of the intelligent network service operator 50. However, such a service development environment 60 may be accessed only by the network provider or the intelligent network service operator 50, and the generated service may also be serviced only by a specific intelligent network device provided by the network provider, that is, the service control system 30. Therefore, the subscriber of the intelligent network service is limited to subscribe to the service provided by the service control system 30 that is the intelligent network device. Intelligent network services have the limitation of being defined and serviced within a closed network of intelligent network devices. However, the intelligent network devices 30, 60, and 70 except for the service exchanger 20 may be easily connected to the Internet because they are based on a commercial computer system.

Thus, such a service development environment of the related art can be accessed only by a network provider or an intelligent network service operator, and the generated service can only be serviced by a specific intelligent network device provided by the network provider. That is, in the conventional service development environment, there is a problem in that an intelligent network service subscriber needs to receive a service only through the intelligent network device.

In order to solve the above problems, the present invention provides an additional function in a service provider system of a network provider so that an intelligent network service subscriber (service provider), which is not a network provider or an intelligent network service operator, can provide a service using his device. Its purpose is to make it possible.

It's there.

Another feature of the present invention for achieving the above object is that the service exchange collects the digits to determine whether it is an intelligent network call, and if it is determined that the intelligent network call is not an intelligent network call in the intelligent network call determination step, the service exchanger processes the service from the beginning. If it is executed again and the intelligent network call is determined in the intelligent network call determination step, the service exchanger requests a query to the service control system, and the service logic in the service control system that receives the service request analyzes the message to determine the requested service number. Determining whether the number is to be sent to the subscriber's device; if it is determined in the service number determination step that the requested service number is not the number to be sent to the service subscriber's device, the service control system performs intelligent network service call processing and then If the service number is determined to be the number to be sent to the service specific subscriber's device in the service number determination step, the service control system delivers the service subscriber's Internet address and message contents to its gateway function. Reconstructing the message and requesting a query to a service subscriber device such that the gateway function receiving the message requests a service subscriber from the Internet address and the content of the message. The gateway server in the service control system performs a service for the corresponding number with its service logic by the service server in the service subscriber device receiving the service request from the function, and returns the result value back to the gateway function in the service control system. Lies in comprising the steps of the service control system transmits a gateway functionality result was waiting for the result values back to the service exchange, and again performed from the beginning to pass by.

Another feature of the present invention for achieving the above object is that the service control system receives a subscriber service result from an intelligent network intelligent network service request message or a gateway from a service exchange, when receiving the subscriber service result in the input step, the connection or After generating a protocol message PDU (Protocol Data Unit) for a result operation by service, sending a connection or a result operation for each service to a service exchange and terminating, and receiving the intelligent network intelligent network service request message in the input step, it is determined whether it is a service access code in the message. In the analyzing step, if it is determined in the analysis step that the subscriber service is not a service access code, the service is performed from the beginning after performing the service with service logic. Determining that the subscriber service number exists in the database if the service code is determined to be a root code; and if the subscriber service number is not found in the database in the existence determination step, the service value is transmitted to the service exchanger by putting the service unavailable value in the result value in the connection message And if it is determined that the subscriber service number exists in the database in the presence determination step, determining whether the number of parameters required by the corresponding subscriber number is two or more, and in the parameter determining step, If it is determined that the number is less than 2, the subscriber number, the Internet address, and the subscriber service server name of the corresponding number are retrieved from the database and transmitted to the gateway function. If it is determined that the number is 2 or more, generating a protocol message PDU for a user information collection operation to request additional information from the user; transmitting the collected information to a service exchange and waiting for the user information collection result; The information gathering result is received from the service exchanger and assigns the information gathering result to the parameter value, and transmits the subscriber subscriber number, the Internet address, the subscriber service server name and the parameter value of the number to the gateway function. have.

Another feature of the present invention for achieving the above object is the step of receiving a subscriber service request message from the functional entity access manager of the service control system or the subscriber service results from the subscriber service server, inputting the subscriber service request message in the input step When receiving, the gateway function generates a service request message with the content of the data transmitted to request the service from the service subscriber's device, and starts a client process requesting data processing from the subscriber's device. Requesting, receiving the subscriber service result in the input step, analyzing the data stream in the result file, extracting data required for the service result, and delivering the subscriber service result to the functional entity access manager; To step lies in made.

In order to design a network structure in which an intelligent network service subscriber (service provider), which is not a network provider or an intelligent network service operator, can provide a service using his own device, the intelligent network service control system and the Internet are added by adding a gateway function. This gateway function provides a passage for service between the service user and the service subscriber connected to the Internet, which enables the intelligent network service subscriber to provide the service in the subscriber's own device in addition to the service of the network provider or the intelligent network service operator. Will be.

4 is a flowchart of a subscriber service process in an open structure of an intelligent network to which the present invention is applied. Referring to Figure 4, it will be described the subscriber service process of the open structure of the intelligent network to which the present invention is applied.

In S1, the service exchanger receives a digit requesting the intelligent network service from the telephone caller. In S2, the service exchange collects and analyzes the requested digit. In S3, the service exchanger determines whether the intelligent network service call is requested.

If it is determined in S3 that the request is not an intelligent network service call, then S4 processes the corresponding service and starts again from S1. If it is determined in S3 that the intelligent network call request, in S5 the service switcher requests a query to the service control system. In S6, the service logic in the service control system receiving the service request analyzes the message. In S7, the service control system determines whether the requested service number is to be sent to the service subscriber's device. If it is determined in S7 that the service number requested is not a number to be sent to the service subscriber's device, in S8 the service control system performs the existing intelligent network service call processing and performs again from S1. If it is determined in S7 that the requested service number is to be sent to the device of the service specific subscriber, the service control system performs service number-to-Internet address mapping in the service control system. In S10, the service control system delivers the service subscriber's Internet address and message content to the gateway function in the service control system. In S11, the service control system reconfigures the message so that the gateway function receiving the message requests the service subscriber with the Internet address and the content of the message. In S12, the service control system requests an inquiry to the device of the service subscriber. The gateway function waits for a response from the service subscriber's device. In S13, the service server in the service subscriber apparatus that receives the service request from the gateway function in the service control system performs the service for the corresponding number with its service logic. In S14, the service subscriber station transfers the performance result value back to the gateway function in the service control system. In S15, the service control system transmits the gateway function result value, which has been waiting for the result value, to the service exchanger again and starts again from S1. In addition, protocols for the service subscriber's service should already be defined between the service subscriber and the network provider or intelligent network service operator.

Referring to Figure 5 will be described the process in the intelligent network service control system for services provided in the device of the intelligent network service subscriber of the present invention.

In S21, the intelligent network service request message is received from the service exchanger to the intelligent network service control system. In S22, the service access code (SAC) in the message is analyzed. In S23, the service type is determined. At this time, the service request number of the request message requested from the service exchange has a structure of SAC + service number. If it is determined in S23 that the subscriber service is not the SAC, in S24, the service is performed with the existing service logic and the service is performed again from S21. In step S23, if the subscriber service is determined to be SAC, S25 opens a database for mapping the subscriber service number to the Internet address (Open). In S26, it is determined whether the subscriber service number exists in the database. If it is determined in S26 that there is no subscriber service number in the database, in S27, a service unavailable value is added to a result value in a connect message and transmitted to the service exchange and terminates. If it is determined in S26 that there is a subscriber service number in the database, it is determined in S28 whether the number of parameters required by the corresponding subscriber number is two or more. If it is determined in S28 that the number of parameters required by the corresponding subscriber number is less than 2, S29 retrieves the subscriber number, the Internet address, and the subscriber service server name of the corresponding number from the database and transmits them to the gateway function. If it is determined in S28 that the number of parameters required by the subscriber number is 2 or more, S30 generates a protocol message PDU for a user information collection operation to request additional information from the user. In S31, the collected information is transmitted to the service exchange. In S32, the user information collection result is awaited. In S33, the user information collection result is delivered from the service exchange. In S34, the information collection result is assigned to the parameter value. In S35, the subscriber subscriber number, the Internet address, the subscriber service server name of the corresponding number, and the parameter value are transmitted to the gateway function.

In S36, the subscriber service result is received from the gateway. In S37, a protocol message PDU is generated for the result operation by connection or service. In S38, the resultant operation by connection or service is sent to the service exchange and terminates.

6 is a detailed flowchart of the gateway function. Referring to Figure 6 describes the detailed process of the gateway function as follows.

In S41, a subscriber service request message including a subscriber number, an Internet address, and a subscriber service server name of the corresponding number is received from a functional entity access manager of the service control system. In S42, the gateway function generates a service request message with the content of the data transmitted to request the service to the service subscriber's device. In S43, a client process which requests data processing to a subscriber's device is driven. In S44, a service is requested to the server of the subscriber device. In S45, a subscriber service request message including a subscriber number, an Internet address, a subscriber service server name of the corresponding number, and a parameter value is received from a functional entity access manager of the service control system. In S46, the gateway function generates a service request message with the content of the data delivered to request the service from the service subscriber's device. In S47, a client process that requests data processing is driven to the subscriber's device. In S48, the service request is made to the service of the subscriber device. In S49, the subscriber service result is delivered from the subscriber service service. In S50, the data stream in the result file is analyzed. In S51, data necessary for the service result is extracted. In S52, the subscriber service result is transmitted to the functional entity access manager.

As described above, the present invention has the effect of providing a service to a service user through a public switched telecommunication network using a service subscriber's own device and service logic even if the device is not a device of a specific network operator such as a service control system. There is. In addition, the present invention has another effect in that problems such as service distribution and subscriber profile distribution can be solved by opening services, which were only available in a closed structure based only on an intelligent network device, through access to an open network.
