Description

Intelligent service implementation method and access method and system thereof

The present invention relates to an implementation process of an intelligent service and an intelligent service system thereof, and particularly to an implementation method, an access method and a system thereof for an intelligent service. Background of the invention

The Intelligent Network is a concept standardized by CCITT in 1992. It is a system that can generate and implement various new services quickly, conveniently, flexibly, economically and efficiently. The goal of this system is to serve all communication networks.

The basic structure of the intelligent network is shown in Figure 1. Figure 1 is a schematic diagram of the basic structure of the intelligent network. The package includes a terminal device 101, a transport network 110, a service switching node/smart peripheral (SSP/AIP) 120, and a service control node (SCP) 130.

The terminal device 101 may be a fixed telephone or a mobile phone. The transmission network 110 may be a public switched telephone network (PSTN) or a next generation network (NGN), or may be a wireless communication network such as GSM or CDMA.

Service Switching Node / Intelligent Peripheral (SSP/AIP) 120: The SSP implements call processing functions and service switching functions. AIP is a dedicated resource that assists in the completion of intelligent services. It usually has voice functions, such as voice synthesis, playing recorded announcements, receiving dual-tone multi-frequency dialing, and performing voice recognition. AIP can be a standalone physical device or part of an SSP.

SCP130 is the core functional component of the intelligent network. It stores user data and business logic. Its main function is to receive the query information sent by the SSP and query the database for various decoding. At the same time, it can initiate different service re-sequences according to the call events reported by the SSP, and issue call control commands to the corresponding SSP according to the service's logic, thereby implementing various intelligent calls. At present, the intelligent online has opened the called centralized payment service, calling card service, virtual private network service, additional charging service, wide area centralized user switching service, universal number service, networked emergency telephone service, mass calling service, called paying call Transfer business, personal business and other services.

The calling card service is also called the billing card calling service. Simply put, the billing card calling service allows the user to place a call on any of the two-tone telephones and record the charge on the specified account. This number is included in the card number of the billing card. When the user uses the billing card to call the service, he only needs to dial the service access code on any audio telephone in the area where the service can be provided, and then input his own card number and corresponding password from the telephone according to the voice prompt. After the system checks and confirms the entered card number and password, the user can dial the called number to make a call just like a normal call. For example: 200 cards, 201 cards, 300 cards, IP cards, and Yitong cards are all password card transactions.

Take the 200 service as an example. When accessing the service, the user needs to perform the following operations:

1. User input 200, voice prompt "Welcome to 200 service, please enter the card number";

2. After the user enters the card number of 10 or more digits, the voice prompts "Please enter the password, ,;"

3. After the user enters the password of 6 digits or more, the voice prompts "Please dial the called number";

4. The user enters the called number.

It can be seen that when the user accesses the 200 service, the user needs to input a cumbersome card number and password, and if the input error still needs to be re-entered, it is troublesome to use.

The same billing service provided by the intelligent network has the same problem. Additional billing business, the single bill is that the intelligent network provides a paid account, you can pay with your own account, including water, electricity, online shopping and so on. When using the additional billing service, the user only needs to dial the service access code on any audio telephone in the area where the service can be provided, and then input the items, accounts and corresponding items to be paid from the telephone according to the voice prompt. Password, when the system checks and confirms the entered account number and password, the system performs the corresponding payment operation. User at ' The following operations are required to access the service:

1. The user inputs an access code and selects a payment item according to the voice prompt;

2. After the user enters the account according to the voice prompt, the voice prompt "Please enter the password";

3. After the user enters the password, the system queries the fee for the paid item, and after the corresponding operation, notifies the user of the payment.

In this way, when accessing the additional billing service, the user needs to memorize the account, and needs to input a cumbersome account and password during operation. Once the input is wrong, it needs to be re-entered and used. It is troublesome.

In addition, for a service such as a universal number, the user also needs to remember the access code, the universal number, the password, and the like, and the user needs to manually input the above information when registering the service. For example, for a one-number service in which multiple numbers of multiple communication terminals of a user occur, the user can associate multiple communication terminal numbers owned by the user with a one-number communication number, and only publicize the number to other users. When dialing this number, the No. 1 service is responsible for translating into the real number associated with the user.

The One Number service provides the ability for a user to associate the communication device number they use by telephone to their own number one. The traditional practice of this function is to require the user to dial a number to access the one-number service, enter its number one number and password, and perform number association according to the voice prompt. This association process is also the registration process of the one-number service.

In this way, the operation is relatively cumbersome for the user, and the user needs to remember and input the relevant information such as the access code, the number one number, and the password.

The manual dial-up registration of the No. 1 service refers to the user entering the access number of the No. 1 service by means of a button, and inputting the No. 1 number and password according to the voice prompt. Complete the association operation between the currently used calling number and the one-number number.

Manual dialing to register the No. 1 service will bring the following problems:

1. The manual dial-up registration phone solution requires the user to remember the access number of the No. 1 service. The information brings an additional memory burden to the user.

2. The manual dial-up registration phone solution requires the user to manually input the access code, the number one number, and the password of the one-number service. The operation is relatively cumbersome, and there is still the possibility of input errors during operation, which is inconvenient to use.

3. The manual dial-up registration phone solution requires the user to manually enter the number and password of the first number. The security is relatively poor. The user may be seen by others during the process of entering the number, resulting in the theft of the number.

It can be seen that a variety of intelligent services opened on the intelligent network have the problems of memorizing various information, cumbersome input and low input security when the user operates. Summary of the invention

In the embodiment, the FSK audio signal demodulation unit 311 is disposed in the SSP/AIP device 310. In an actual application, if the audio card transmits the service access code, service information, or user information through the DTMF signal, the SSP/AIP is sent. A DTMF audio signal demodulation unit is provided in the device for demodulating the signal. The terminal device in this embodiment is a fixed telephone, and the transmission network may be a PSTN network or an NGN network. In practical applications, the terminal device may also be a mobile terminal or a computer-connected microphone; the transmission network may be a wireless communication network such as GSM or CDMA.

The authentication unit in this embodiment is an authentication server that interacts with the SCP through the TCP/IP protocol. In an actual application, the authentication unit may also be an authentication module in the SCP.

FIG. 4 is a flow chart of registering the No. 1 service to the intelligent service system shown in FIG. 3. In this process, the one-number service access code and the service information including the user registration number and the user password are stored in advance in the audio smart card. The process includes the following steps:

Step 401: The fixed telephone 330 first receives the DTMF audio signal of the service access code sent by the audio smart card 340, and sends the DTMF audio signal to the switching device of the PSTN network 320. After the predetermined time, the fixed telephone 330 receives the FSK of the registered service information sent by the audio smart card 340. The audio signal is sent to the switching device of the PSTN network 320.

Step 402: The switching device receives the DTMF audio signal of the service access code, and sends the FSK audio signal of the received registration service information to the SSP/AIP device 310 through the PSTN network 230 according to the service access code.

Step 403: After receiving the audio signal, the SSP/AIP device 310 determines, according to the characteristics of the received audio signal, whether the signal is an audio signal sent by the audio smart card 340. If yes, step 404 is performed; otherwise, the original smart service is pressed. Way to read the registration service from the signal

^ Interest.

Step 404: The FSK audio signal demodulation unit 311 in the SSP/AIP device 310 demodulates the FSK audio signal of the received registration service information, and sends the demodulated registration service information to the SCP 300 of the intelligent network.

In step 405, the SCP 300 stores the received user registration number and user password, and registers the one-number service for the fixed telephone 330. After the service registration No. 1 service of the embodiment is adopted, the registration operation of the user in the intelligent service can be simplified.

In the actual use process, the user can pick up the handset of the phone first, and trigger the DTMF audio signal by pressing the corresponding button of the audio card. After receiving the DTMF signal, the phone sends the DTMF signal to the PSTN network terminal switch device, and the switch device pairs the DTMF signal. After analyzing, and then accessing the one-number service, the one-way service completes the associated registration of the current number of the first caller and the user. In this way, the DTMF signal is sent by using the audio technology, and the associated registration of the one-number number and the calling number is completed at one time.

The audio signal is used to complete the association registration of the one-number number and the calling number at one time, and the first-number access number, the first-number number, and the first number communication number need to be sent to the switch at one time. In this way, there may be cases where the number is too long and the switch device cannot receive the number. To this end, the second round of the number is used in this process to complete the associated registration of the number one and the calling number. That is: the user first uses the audio card to send the DTMF signal, accesses the No. 1 service, and then uses the audio card to issue the FSK signal, and sends the No. 1 number and password to complete the registration of the No. 1 number and the calling number. .

It can be seen that when the user of the present invention registers the No. 1 service, it is no longer necessary to input a cumbersome service access code, a number one number and a user password, which can prevent input errors and is more convenient to use.

FIG. 5 is a schematic flowchart of accessing the intelligent service system shown in FIG. 3.

The user information in this process is the card number and password of the encrypted calling card service, and may also be only the card number of the encrypted calling card service. In actual applications, the user information may not be encrypted. In addition, the user information may be a user account when implementing the additional charging service; or may be a user account and a password, and may or may not be encrypted. In fact, the audio card can be used to store any digital information, not limited to the user information such as the card number and account number mentioned above. Therefore, in practical applications, the audio card can also be used to store other digital information that needs to be input into the system. The process includes the following steps:

Step 501: The fixed telephone 330 receives the intelligent service access code input by the user, and sends the data to the SSP/AIP device 310 through the PSTN 320.

Step 502: The SSP/AIP device 310 sends a prompt message to the user through the PSTN 320 using the fixed telephone 330 according to the access request, and requests the user to input the card number and password.

Step 503: The fixed telephone 330 receives the FSK audio signal sent by the user using the audio smart card 340, and sends the audio signal to the SSP/AIP device 310 via the PSTN 320.

Step 504, the SSP/AIP device 310 receives the audio signal sent by the PSTN network 320, and determines whether it is an FSK audio signal according to the characteristics of the received audio signal. If yes, step 505 is performed; otherwise, other audio signals are received. Execute the original intelligent business process.

Step 505: The FSK audio signal demodulation unit 311 in the SSP/AIP device 310 demodulates the received signal, and transmits the demodulated encrypted user card number and password to the SCP 300.

Step 506, the SCP 300 queries the last demodulated encrypted user card number and password recorded in the database, and the SCP 300 demodulates the encrypted user card number and password and the previously demodulated encrypted user card number and The password is sent to the authentication server 301 requesting authentication.

Step 507, the authentication server 301 first authenticates the demodulated encrypted user card number and password according to the previously demodulated encrypted user card number and password. If the authentication is passed, step 508 is performed; otherwise, the authentication fails. The authentication server 301 returns the authentication failure information to the SCP 300, and the SCP 300 notifies the SSP/AIP 310 that the SSP/AIP 310 uses the fixed telephone 330 to issue a user card number and password incorrect voice prompt to the user via the PSTN 320, and prompts the user to re-enter the user card number. And the password, the user re-enters and returns to step 503, and the user does not input to end the process.

Step 508, the authentication server 301 sends the encrypted encrypted user card number and password to the SCP 300, and the SCP 300 decrypts the encrypted user card number and password. Step 509: The SCP 300 authenticates the user card number and password, and if the authentication succeeds, accesses the intelligent network and continues to execute the intelligent service. Otherwise, the SCP 300 notifies the SSP /AIP 310 that the SSP /AIP 310 sends the user's card number and password incorrect voice prompt to the user through the PSTN 320, and prompts the user to re-enter the user card number and password. After the user re-enters, the process returns to step 503. , the user does not enter to end the process.

In this embodiment, an authentication server 301 is added to the intelligent service system. In an actual application, the authentication module can be designed as a software authentication module, and is set in the SCP 300. The authentication server or the authentication module may not be set, and the audio smart card is stored in the audio smart card. The card number and password are not encrypted, and the above steps 506-508 are not required. In this embodiment, the authentication server 301 is provided for added security.

After the service access process in this embodiment is used, the user can access the service in the smart service. The 200 service is still used as an example. When the user accesses the service, the following operations are required:

1. User input 200, voice prompt "Welcome to 200 service, please enter the card number and password,;;

2. The user triggers the audio smart card, and the output card number and password are input to the system through the fixed telephone. The system voice prompts "Please dial the called number";

4. The user enters the called number.

It can be seen that when the user accesses the 200 service, it is no longer necessary to input a cumbersome card number and password, which can prevent input errors and is convenient to use.

It can be seen from the foregoing embodiments that the method, the access method and the system for implementing the intelligent service provided by the present invention do not require the user to input cumbersome user information, simplify the operation process of the user intelligent service, and facilitate the use of the user.
