Abstract

PURPOSE: A method for accessing between an intelligent network system and an intelligent peripheral(IP) is provided to introduce an IP to a prior intelligent network system which does not support an INAP protocol. CONSTITUTION: If it is judged that it is required to access to an intelligent peripheral(IP) in order to process a user call while processing the intelligent network call of the user in a service control point(SCP) system or a specific condition is satisfied, an access telephone number of the IP is transferred to a service switched point(SSP)(S1). Then, when the specific condition is satisfied or there is a request from the SCP, the SSP starts to set the IP and the call by including an intelligent network service number into an ISDN user protocol and then transmitting them(S2). The IP executes a corresponding service scenario on the basis of its own access number and the intelligent network service number according to a call set request, and interacts with the service user(S3). And the IP interacts with a service management system for information processing required in the service processing(S4).

Description

Connection method between intelligent network system and intelligent additional device

The present invention relates to a connection method between an intelligent network system and an intelligent additional device, and provides various additional functions in an intelligent network centered on a service control system (hereinafter referred to as SCP) and a service switched point (hereinafter referred to as SSP). Intelligent Peripheral (hereinafter referred to as IP) necessary to provide access to the intelligent network system.

The existing intelligent network service is an application part (TCAP) among common signal system between SSP having basic voice announcement and 'DTMF (Multi-Frequency Signal for MFC Phone)' and SCP having database required for intelligent network service. ) Through the communication using the protocol, only basic intelligent network services such as number translation and subscriber authentication can be provided.

In order to introduce advanced technologies such as various announcements, voice recognition, and voice synthesis into an intelligent network, or to provide various additional functions such as recording a message during or away from a call, an IP having such a processing function is required.

However, there is no way to introduce such IP in current intelligent network system, and there is a method using next generation intelligent network system to introduce IP into intelligent network service, but for this purpose, it supports next-generation intelligent network application protocol (hereinafter referred to as INAP). SSP, service control system and IP are needed.

In the IP access method using the next-generation intelligent network application protocol, the SCP requests the SSP to access the IP, and when the line connection between the SSP and the IP is completed, the SSP uses the INAP protocol based on the line number transmitted to the SCP. It transfers the necessary control on the line directly or indirectly, and uses the function of IP to provide the service user.

Connection method of IP using next-generation intelligent network application protocol Also, SCP must connect IP via SSP, and interworking method is complicated such that it needs to transmit commands such as digit collection or announcement broadcasting through separate direct connection to IP. In order to use IP, there is a disadvantage in that a lot of message flows between systems increases traffic load on the network.

And there is a problem that is not applicable to the existing intelligent network system that does not support the next generation intelligent network application protocol.

In the present invention, in consideration of the above-described problems, in connecting an IP to an intelligent network system, an ISDN user part that is used by the SSP for establishing an existing switching period circuit without using a separate protocol such as a next-generation intelligent network protocol ( By using ISUP) protocol, IP can be connected to intelligent network system.

That is, by sending the intelligent network service number to the selected parameter term (initial call number or call forwarding number) of the initial address message (IAM) transmitted when setting up the call from the SSP to the IP, the corresponding intelligent network service at the same time as the call setup in IP It recognizes the number and starts the service.

The present invention provides an IP and intelligent network service access method using the ISDN user part protocol which is used as a signaling method between stations in the existing exchange period through the above method, thereby providing IP to an existing intelligent network system that does not support the INAP protocol. Its purpose is to allow for introduction.

5: Phone 6: Intelligent Attachment (IP)

7: Service Management System (SMS)

In order to achieve the above object, the intelligent network system and the intelligent additional device proposed in the present invention provide an intelligent additional device for processing a user call when a service control system (SCP) processes an intelligent network call of an intelligent network service user. (1) transmitting a connection telephone number of the IP to the service switcher (SSP) so as to be connected to the IP when it is determined that the connection to the (IP) is necessary or the specific condition is satisfied;

The second step is to start the IP and call setup by sending the ISDN user part protocol including the intelligent network service number when the call is made to the IP when the SSP that receives the access telephone number satisfies a specific condition or according to the request of SCP. ;

A third step of interacting with a service user by executing a corresponding service scenario based on the access number of the second step and the intelligent network service number loaded when the call is made by the SSP according to the call establishment request of the second step; And

Performing a fourth step of interacting with a service management system for processing information required for service processing in IP;

It is characterized by providing intelligent network service through IP using ISDN user part protocol, which is a signaling method between stations.

The above objects, features, and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a hardware configuration diagram of an intelligent network system to which a connection method according to the present invention is applied, comprising: a local exchange 4 which receives a service call from an intelligent network service user 5 using a telephone;

An SSP (3) connected to the local exchange (4) and delivering an intelligent network service call;

A common line signal network (2) connected to the SSP (3) for delivering service control information;

An SCP (1) connected to the common line signal network (2) to perform a function of controlling a service call in a network dimension;

A service management system 7 connected to the SCP 1 to manage service data; And

The ISSP user part protocol is used to set up the line between the SSP 3 and the station, and includes an IP 6 having voice guidance, voice synthesis, voice storage, voice recognition, number analysis, and the like. .

Looking at the operation of the intelligent network system configured as described above are as follows.

When the intelligent network service user calls the intelligent network number, the local exchange 4 routes to the SSP 3 that accepts the intelligent network, and the SSP 3 sends the SCP to the SCP 1 for service control. It is transmitted through common line signal network.

SCP (1) performs necessary control on the received intelligent network, and then determines whether access to IP (6) is necessary (e.g., retrieves the voice message of the subscriber stored in IP, or recognizes voice provided in IP). If it is determined that a connection to IP is required due to a high level of functionality, such as a function, or if certain conditions (e.g., the called party is busy or no answer, etc.) are satisfied in the SSP (3), The access telephone number of IP 6 is sent down to SSP 3 so that the call can be routed.

Upon receiving the access telephone number, the SSP (3) routes the intelligent network directly to the IP (6) based on the service control processing result received from the SCP (1) or, if there is a specific condition, if the specific condition is satisfied, Route intelligent networks to IP (6).

At this time, the access number of the IP 6 uses the same access number as a general telephone, and ISDN user part protocol is used as a signaling method between the SSP 3 and the IP 6 for call connection.

In the initial setup message (IAM) of ISDN user part protocol, IP (6) sets up the connection based on this information. It can know the intelligent network service number of the call and executes the functions required by IP (3).

The above function will be described in detail with reference to the flowchart.

In the connection method between the intelligent network system and the intelligent additional device of the present invention, the intelligent network call of the intelligent network service user is determined to require the connection to the IP 6 in order to process the user call when the SCP 1 processes it, or a specific condition ( For example: a first step of delivering a connection telephone number of IP to the SSP 3 so that a call can be connected to the IP 6 when the called party's busy / no answer is satisfied;

ISDN user part protocol when the SSP 3 that has received the access telephone number in the first step satisfies a specific condition or when using the ISDN user part protocol to set up a call to IP 6 at the request of SCP (1). A second step of initiating call setup with the IP 6 including an intelligent network service number in an initial called number or a called number number of a call from a selection parameter of an initial address message (IAM);

In response to the call setup request of the second step, the IP 6 executes the corresponding service scenario based on its access number and the intelligent network service number loaded when the SSP 3 is set up to interact with the service user. Third step; And

A fourth step of interacting with a service management system (SMS) for processing information necessary for service processing at IP 6;

In more detail, the first step is as shown in Figure 2, which is performed in the SCP (1).

Upon receiving the intelligent network signal from the SSP (3), SCP (1) processes the existing intelligent network service ---- (S1).

When a specific condition that requires an IP connection occurs while performing a service like this, SCP transmits a specific condition and an IP access number to the SSP side (S2), and if not, transmits only the IP access number and terminates. -(S3).

If the IP connection request is not generated during the intelligent network service processing in step S1, the SCP transmits the intelligent network service processing result to the SSP and terminates (S4).

For reference, the processing performed on the messages output in the processes S2, S3, and S4 will be described in each order to be described below, and the portion indicated by 'a' in the figure indicates that the portion is processed in the 'a' portion of the following figure.

In addition, the second step is as shown in Figure 3, which is a process performed in the SSP (3), when the originating number and intelligent network number from the SSP to the SCP side (T1), the result of the existing intelligent network service processing If it is input, the existing intelligent network processing is performed and terminated (T2).

When a specific condition and IP access number corresponding thereto are input (T3), after performing a specific task corresponding to the condition, it is determined whether the specific condition is satisfied, and if it is not satisfied, the existing intelligent network processing is performed and terminated. ---- (T4).

If only the IP access number is input from the SCP, or if the specific condition is satisfied in the 'T4' process, the SSP forwards the intelligent network service number to the ISDN user part protocol initial address message (IAM) by IP ---- ( T5).

For reference, the portion marked 'b' in the drawing indicates that the portion is processed in the 'b' portion of the following figure.

Subsequently, when an address reception completion message (ACM), an acknowledgment message (ANM), or an access message (CON), which are messages indicating that the number transmission message is well received, is received from the IP, the call setup between the user and the IP is executed. --- (T6).

In addition, the third step is as shown in Figure 4, which is a process performed in the IP (6), if the intelligent network service number is entered in the IAS from the SSP, the IP is sent to the message After sending well received message (ACM, ANM, CON) to SSP, perform line setup with user ---- (E1).

Subsequently, the scenario is executed based on the received intelligent network service number and its access number, and if it is not necessary depending on whether or not the interaction with the SMS is required, the processing is terminated by checking whether the end condition is satisfied ---- (E2). .

And if the result of the interaction check with the SMS, IP delivers a message requesting interaction to the SMS side and receives the result from the SMS. Then, the program processing end condition is checked and terminated if it is satisfied. Otherwise, the scenario execution step E2 is repeated.

For reference, the portion marked 'c' in the drawing indicates that the portion is processed in the portion 'c' in the following figure.

In addition, the fourth step is as shown in Figure 5, which is a process performed in the SMS (7), if the interaction is requested from the IP in the third step, the operation for this process is processed and the result is IP Output to ---- (P1).

According to the embodiment of the present invention through the above process, when the personal number is pressed to access the personal number subscriber in the personal number service, SSP requests the translation of the actual number of the corresponding personal number to the SCP, SCP sends the SSP with the actual called number of the personal number and the access telephone number of the IP to connect with the IP providing the voicemail function when the called party is busy or unanswered.

The received SSP routes the call to the actual called number and, if the called party is busy or unanswered, sets the call to the IP access number and delivers the intelligent network service number together.

IP records the voice in the subscriber's voicemail box based on the received intelligent network number.

When an intelligent network service subscriber generates an intelligent network service call to search his voicemail box, the SSP forwards this request to the SCP, and the SCP forwards the telephone number of the IP with the voicemail address of the intelligent network number to the SSP. In other words, the SSP sets the call to the telephone number of the IP received from the SCP.

At the time of call setup, the intelligent network number is transmitted to the IP so that it can perform a management function such as searching, greeting recording, and deleting the message of voicemail of the intelligent network number.

As another embodiment of the present invention, if it is determined that an intelligent network service user needs advanced functions of an IP such as voice recognition or fax reception, the SCP accesses the SSP to an IP capable of processing such functions. To request this, give down the IP number.

The SSP establishes a call with this access number, delivers the intelligent network service number together, and the IP interacts with the user by activating the corresponding function based on the intelligent network number.

As described in detail above, the present invention enables the IP to be used in an intelligent network service by using an ISDN user part protocol, which is an inter-station signaling method used for the existing switching period circuit setting, without implementing separate protocols in the SSP and SCP. In addition to using the advanced function of IP in the intelligent network service, general telephone number can be used as the access number of the IP, which can be installed in any place without restriction on the physical location of the IP. Based on the intelligent network number loaded in the call setup, it provides the service by access number, the service by intelligent network service number, and the service provided by the combination of access number and intelligent network service number.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
