The present invention relates to a service control method using an intelligent network, and a system therefor. The present invention relates to a service control method using an intelligent network that plays sound and a system therefor.

In general, when a caller makes a telephone call to a receiver via a communication network, the caller hears a 'beep' of the machine until the receiver receives a call.

However, if you listen to music or listen to music while listening to the sound, you can apply the economic law that 'time is money' to apply the advertising effect or music effect to the business entity that needs it. It can be doubled to increase sales, and furthermore, it can give tangible or intangible benefits to users by receiving information from consumers, or telephone users, or listening to music instead.

Therefore, in order to implement such a service, an intelligent network is added to the communication network to provide various services to the user, not just telephone communication. Such services include high-level information such as news information, financial information related to securities and bonds, corporate information, etc. in simple services such as voice messages and caller's phone number notification.

Therefore, there is a need to provide a service method that allows the caller to listen to a specific sound such as music using the waiting time.

By request as described above, an object of the present invention is to provide a service control method using an intelligent network and a system therefor.

Another object of the present invention is to provide predetermined information using an intelligent network regardless of different networks when one of the callers and the called party is an additional service subscriber.

Still another object of the present invention is to provide a service control method using an intelligent network which can be easily controlled by assigning an address number to be connected, and a system therefor.

Other systems such as Service Management Point (SMP) are added, but the detailed description is omitted in the present invention for the purpose of understanding the present invention. The present invention will be described based on a wired network but can be applied to a wireless network.

In general, a plurality of landline telephones 10 are connected to the SSP (100) to connect to the intelligent network. SSP 100 not only provides the network access to the user or provides the necessary switching functions for call connection, but also provides full access to the relevant capability groups of the intelligent network. To this end, it includes a sensing capability to detect an intelligent network service request, a communication capability to communicate with other physical entities including SCP 200, IP 300, and a response capability to commands transmitted from other physical entities.

The SSP 100 functionally includes a call control function (CCF), a call control agent function (CCAF) and a service switching function (SSF).

In addition, the SSP 100 may be configured to be integrated with the exchanger, or may be installed separately from the exchanger, or may be configured to replace the exchanger.

SCP 200, on the other hand, has service logic programs and data necessary for intelligent network service processing and is connected to SSP 100 through a signaling network. Multiple SCPs can contain the same service logic program or data to improve the quality of service or to share the load between SCPs.

The IP 300 may provide resources that may be provided by the exchange as well as special resources that are difficult to provide in the exchange or the SSP 100 to support input and output of various information between the communication user and the network.

That is, IP 300 provides flexible interaction between user and network with resources such as customized announcement, speech / language synthesis and recognition device, DTMF digit collector, audio conferencing bridge, information distribution bridge, tone generator, etc. do.

Therefore, the user accesses and stores a web server 30 or an interactive voice response system 40 (IVR) through an internet network or a public switched network to provide his or her own voice, and the like. The manager (content provider) of the 40 can send the category, recipient telephone number, IP (the category) to the master server 400 so that the IP 300 can transmit the standby sound instead of the mechanical sound to the telephone 10 connected to the SSP 100. 300) store the data required and match to match each other. If necessary, the program code may be mounted on the SSP 100, the SCP 200, the IP 300, or the master server 400 and matched with each other.

In the present invention, the information of the service requested by the subscriber, such as voice or music, is transmitted to the database in the IP 300 by matching and signal transmission and reception between the SSP 100, the SCP 200, and the IP 300. Stored and implemented, the SSP 100, SCP 200 and IP 300 are configured to share or solely own subscriber information such as service subscriber status, subscriber number, supplementary service data, and the like.

In addition, the provision of supplementary services is equally applicable to providing the other party with the information requested by the subscriber regardless of the case where the user of the calling party or the called party subscribes. For example, the called party can provide the additional service to the calling party, as well as subscribe at the calling party and the calling party can be provided.

Therefore, in the present invention, it is configured so that the user can be provided to the calling party or the called party's phone by matching it when searching for a subscriber and is explained based on this.

In addition, a signal transmitted to an exchange or an SSP can be understood as transmitting a signal to a telephone connected to the exchange or an SSP, and in the case of information such as music, it can be understood to provide the corresponding data, and vice versa. Do.

Assuming that the user of the receiving telephone 120 is subscribed to the calling telephone 110 so that a waiting sound such as voice or music can be transmitted instead of a mechanical sound when a telephone is called to the telephone, referring to FIGS. 2 and 4. A first embodiment of a service control method using an intelligent network according to the present invention will be described.

When the user of the calling party's telephone 110 picks up the telephone and inputs the receiving party's telephone number to be called by the telephone, an initial address message (IAM) is transmitted to the switchboard or the SSP 100 (S10). Here, in the case of the local call, all of the telephones 110 and 120 are connected to the SSP 100, and in the case of the local call, the receiving side SSP is referred to.

Then, the SSP 100 analyzes the transmitted information and reads whether the destination telephone 120 is a subscriber of the sound source information (standby sound) service and, if the subscriber is not a subscriber, an address completion message (ACM: Address) to the calling telephone 110. Complete message) and call the receiving telephone 120 to transmit a machine tone to the calling telephone 110 until the receiving telephone 120 receives it.

On the other hand, the SSP 100 transmits a call setup request (CSR) to the SCP 200 when the called party 120 is a subscriber (step S20), and the SCP 200 controls the standby sound service. Allow to do it.

In the next step S30 SCP (200) is a service by transmitting the IP 300 that can provide additional service information, such as subscriber information, subscriber information, subscriber phone number, standby sound information, such as subscriber phone information stored in its database At the same time, the SSP 100 provides the relevant voice and music data for the user of the calling party's telephone 110 to provide a standby sound service such as voice and music until the called party's telephone 120 is received. The connection address number of the IP 300 is transmitted to the SSP 100 so that the IP 300 can be connected.

Here, the access address number of the IP 300 refers to a virtual telephone number or a subscriber telephone number and other routing address numbers, so that the SCP 200 and the SSP 100 can transmit and receive predetermined information when necessary.

After the steps S10 to S30 described above, the SSP 100 accesses the IP 300 corresponding to the access address number and requests a call setup to provide a service set by the subscriber (S40).

The IP 300 receiving the call setup request transmits an ACM signal to the SSP 100 to provide resources related to service-related information received from the SCP 200 in step S30, for example, voice and music corresponding to an atmospheric sound service. In operation S50, the SSP 100 transmits an ACM signal to the calling telephone 110 to open a passage through which an additional service can be provided (S60).

Then, in order for the user of the calling party's telephone 110 to receive the additional service, the IP 300 retrieves predetermined data corresponding to the information such as voice and music corresponding to the additional service from its own embedded database and searches for the SSP. It transmits to 100 (S70). Here, the predetermined data means data digitized as information itself such as voice and music.

When the SSP 100 receives the predetermined data, the SSP 100 transmits the data to the calling telephone 110, and the user of the calling telephone 110 may be provided with the predetermined data. You can listen to music.

Subsequently, the SSP 100 or the SCP 200 transmits a call signal to the called telephone 120 (S80), and when the user responds to the reception, the SSP 100 transmits the received signal to the SCP 200. At the same time, an answer message signal (ANM: Answer Message) is transmitted to the calling telephone 110 (S90). When the call signal is transmitted in step S80, the SCP 200 controls the switch or the SSP 100 to call the ring signal to the exchange.

Next, after the SCP 200 transmits a control signal to the SSP 100 to stop the transmission of the additional service data (S100), it releases the resource occupation between the SSP 100 and the IP 300 (S110).

And SCP (200) makes a call connection between the calling phone 110 and the called phone 120 is connected to each other to enable a telephone call (S120). When step S120 is completed, a call is made and upon completion of the call, SSP 100 and SCP 200 release the call.

Next, a second embodiment of service control logic using the intelligent network of the present invention will be described.

In the control logic of the first embodiment described above, steps S10 to S80, that is, the SCP 200 is the same until the process (step S80) of transmitting the call signal to the called telephone 120.

Then, when the user of the called party's telephone 120 responds to the reception, the SSP 100 transmits the received signal to the SCP 200 (S90-1). This response ANM signal is not transmitted.

Subsequently, the SCP 200 transmits a control signal to the SSP 100 to stop the transmission of the additional service data (S100-1), and then releases the resource occupation between the SSP 100 and the IP 300 (S110-). One).

And SCP (200) makes a call connection between the calling phone 110 and the called phone 120 is connected to each other to enable a telephone call (S120-1). After the step S120-1 is completed, the SSP 100 transmits a response message signal (ANM: Answer Message) to the calling telephone 110 to proceed with the call (S120-2).

Next, a third embodiment of service control logic using the intelligent network of the present invention will be described (see FIGS. 2 and 5).

In the control logic of the first and second embodiments described above, steps S10, S20, and S70 and below are the same.

SCP 200 retrieves subscriber information stored in its database, such as subscriber status, subscriber's phone number, and additional service related information such as waiting sound, reports to SSP 100 when a call event occurs, and requests specific information. And transmits an access address number to the IP 300 to be connected (S30-1), and information about this means a virtual telephone number or a subscriber telephone number and other routing address numbers, and if necessary, the SCP 200 and the SSP 100. Can transmit and receive predetermined information.

Subsequently, the SSP 100 requests a call setup to the IP 300 providing the additional service requested by the subscriber (S40-1). That is, IAM signal is transmitted.

Then, the IP 300 receiving the call setup request transmits the ACM signal to the SSP 100 (S50-1), and then the SSP 100 transmits the ACM signal to the calling telephone 110 to provide additional services. Open the passage that can be provided (S60-1).

Then, in step S30-1, the IP 300 receives the call setup request from the SSP 100 or the SCP 200 directly requesting additional service information requested by the subscriber, or via the SSP 100, 200, indirectly requests the corresponding information (S60-2). The reason for assigning multiple channels for requesting information is that it is set in case of heavy load or communication failure between channels. In this case, the corresponding information means, for example, corresponding voice or music data when the additional service is a standby sound service.

Subsequently, the SSP 100 or the SCP 200 commands the resource occupation directly to the IP 300, or the SCP 200 commands the resource occupation indirectly to the IP 300 via the SSP 100 (S60). -3).

Then, after step S70 in the first or second embodiment, the process proceeds selectively.

Call connection is made with.

The called party SSP 100 then provides the predetermined information to the calling party phone 110 according to the control logic of the first to third embodiments.

Therefore, the same applies to the case where the calling telephone 110 is a landline telephone and the called telephone 120 is a mobile terminal such as a mobile phone.

Of course, this is possible in an environment where network matching between wired and wireless carriers can be achieved.
