Description

Method for processing outgoing call using terminating Basic Call State Model}

The present invention uses a basic call state model (hereinafter referred to as 'BCSM') function to specify the routing number when the operator occupies the outgoing route registered in advance by the operator. This method relates to an outgoing call processing method using an incoming basic call state model concept that provides the ability to route.

An intelligent network (IN) is used to provide various services to a general telephone network. The intelligent network is a structural concept considered to facilitate the introduction of new services and the provision of capabilities in such a telecommunication network.

The functional requirements for these intelligent networks are largely divided into user requirements (service requirements) and operator requirements (network requirements).

Service and network requirements can be defined in the areas of service development, service management, service processing and network interworking.

Among them, service processing is basic call and additional service processing procedure that executes network functions serially or in parallel so that basic and supplementary services can be provided to users, and network interworking is a process for managing multiple services between intelligent network, intelligent network, or intelligent network and non-intelligent network. It is a process of working together to provide.

The BCSM of AIN (Artificial Intelligent Network) ITU-T Q.1224 is recommended as a call processing function model during the service processing. BCSM is a universally recognized model of call control models.

Hereinafter, the BCSM to be mainly mentioned in the present invention will be described.

BCSM is not a functional entity, but it does provide an abstract model for the part of the switch that implements connection control and basic calls to secure the communication path.

Components of BCSM include Points In Call (PIC), Detection Point (DP), BCSM transitions, and events.

PIC is a call control function that shows the progress of a call by classifying the basic call processing procedures that need to be processed by the exchange in order to establish a quantum call.

As mentioned above, the incoming BCSM is recommended, but the incoming BCSM is used only as an intelligent network service and is not introduced to the outgoing relay line of the relay switch.

Up to now, in order to improve the operation and efficiency of various networks of operators, it is possible to change the calling number and the called number by using the insert digit and the delete digit using route information such as route ID. The number was changed using the function.

Hereinafter, a number change operation according to the related art will be described with reference to FIG. 1.

1 is a flowchart of a number change operation using a route sequence of a conventional outgoing call processing.

As shown in FIG. 1, when the outgoing line occupancy request occurs and the outgoing process is executed (S10), it is determined whether the registered state is registered to change a number for a specific number in the root sequence (eg, DEL_DGT). (S11).

If it is determined in S11 that the current number is not registered in the number change work list, the call processing proceeds to the relay line linked through the corresponding route by performing general call processing (S13) (S14).

However, if it is determined in S11 that the current number is registered in the number change work list, the caller deletes DEL_DGT counts from the called party (S12) and proceeds to call relaying through the corresponding route (S14).

However, such a conventional method is restricted in changing various numbers when it is transmitted to a power station by occupying a specific outgoing route, and in order to apply the incoming BCSM in the relay exchange, it processes data handling and outgoing network call for outgoing route. There is a need to define a detailed specification so that a function of triggering to a service control system, reception processing of an intelligent network application protocol received from a service control system, and the like can be implemented in an exchange call processing dispatcher.

Therefore, the present invention has been made to solve the above problems, and when the operator registers data for the outgoing route that may have the meaning of the incoming call to the service control point at the time when occupying the route using the recommended BCSM It is an object of the present invention to provide an outgoing call processing method using a basic call state model for triggering and allowing a call processing to be routed to a specific section based on a specified value.

Outgoing call processing method using the incoming basic call state model concept according to the present invention for achieving the above object comprises the first step of translating the number for the calling number and processing routing; A second step of processing an outgoing call to an outgoing route that has received a current call processing request according to an outgoing occupancy request; A third step of comparing a route ID, a service access code, and a station number to determine whether an incoming BCSM (Basic Call State Model) is registered in the outgoing route; If the incoming BCSM is registered, it is an intelligent network call, so it transmits a trigger signal indicating the intelligent network call to the service control system, and changes the called or originating number to a specified value so that call processing is routed to a specific section by a user setting. process; And if the incoming BCSM is not registered, since it is a general call, not a non-intelligence network call, there is a characteristic consisting of a fifth process of processing as a general call and transmitting to the large country.

The fourth process includes steps 4-1 in which a detection point, a calling number, a called number, a route number, and the like are transmitted to the service control system; Step 4-2 of processing a service such as a number change according to a user setting in the service control system; And a fourth step of changing the number to the corresponding calling number and called number according to the result of the service processing such as changing the number and transmitting the number to the power station to perform call processing.

The outgoing call processing process using the concept of the incoming basic call state model further includes determining whether an event has occurred and informing the event control BCSM of the service control system of the event when the event occurs.

The third step of determining whether the incoming BCSM is registered is a process in which the network operator registers in advance a trigger determination condition such as a called number, calling number, actual input number, calling category, station number, service access code, and billing number. It is made to include more.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

2 is a flowchart illustrating an outgoing call processing method using an incoming basic call state model concept according to an embodiment of the present invention.

As shown in Figure 2, outgoing call processing method according to the present invention, when the origination is first made by the user (S100), the number is translated using the number translation table according to the calling number and the routing (routing) Process to be connected (S200).

When the outgoing occupancy request comes in through the number translation and routing for the calling party and the called party according to the caller's call, the outgoing controller performs the outgoing process (S300).

When the outgoing process is executed, it is checked whether the incoming BCSM is registered in the outgoing route that has received the current call occupancy request (S400).

If the incoming BCSM is not registered, since it is a general call, it is treated as a general call in the conventional manner (S500), and direct transmission and call processing are performed without changing the number (S600).

When the incoming BCSM is registered in S400, since it is an intelligent network call, it is connected to a service control system (SCP) because it must receive the intelligent network service (S410).

When the service operation for changing the number of the calling party and the called party is performed in the service control system (S420), the transmission and the call processing are performed according to the changed information (S600).

As a result, the general call and the intelligent network call are determined according to the incoming BCSM registration and the corresponding call processing is performed.

When an event occurs while performing call processing (S700), the event information is transmitted to the service control system to monitor the event situation and is reported (reported) (S410).

Hereinafter, the outgoing call processing method will be described in more detail with reference to FIG. 3.

3 is a timing diagram of an outgoing call processing procedure using the concept of an incoming basic call state model according to an embodiment of the present invention.

As shown in FIG. 3, when the outgoing line occupancy request signal is generated in the outgoing control unit 10, the outgoing control unit 10 checks whether the incoming BCSM is registered to determine whether it is an intelligent network call or a general call.

In a general call, the incoming BCSM is not registered, so the outgoing exchange generally performs the process and sends the call to the power.

On the other hand, if the incoming BCSM is a specific route requiring the registered intelligent network call processing, the outgoing control unit 10 transmits a trigger signal indicating that the intelligent network call to the service exchanger 20.

Triggers are used to identify the distinction of intelligent network calls and are defined by the network operator.

In order to define the trigger time, the network operator operates various trigger judgment conditions such as called number, input number, calling number, calling category, station number, service access code, and billing number according to the way the network operator wants to operate. Register in advance on the route.

The items that become the primary DP (Detection Point), which are essential registration items for performing the intelligent network service, are a root ID, a service access code, and a station number.

When the trigger is detected at the service exchanger 20, an initial DP is provided to the service control system (SCP) 30 for intelligent network call processing.

When the service control system 30 transmits a connect signal together with the change information on the calling party and the called party, the service exchanger 20 changes the number according to the information received from the service control system 30 to control the outgoing control unit. Transfer to (10).

Therefore, the outgoing relay control unit 10 transmits to the power station through the route corresponding to the number according to the changed information.

At this time, when an event occurs, the event generation information is transmitted to the service control system 30 so that the monitoring (monitoring) function for call processing can be performed.

On the other hand, a detection point is provided for the control of the intelligent network, and when a detection point is encountered during call processing, a certain matter is detected by the detection point.

In particular, additional detection points are created to enable event reports. The functions of additional detection points are as follows.

-Incoming call and call availability analysis (T_Null & Authorize Termination_Attempt)

Incoming response (T_Answer)

-No Answer (T_NoAnswer)

-Incoming call (T_Busy)

-Abandon incoming call (T_Abandon)

-Call forwarding (T_Disconnect)
