The present invention relates to an interface method between a service interaction management unit and a detection point (DP) processing unit installed in an advanced intelligent network service exchange.

In the early intelligent network switch, each intelligent network service processing block and application process and application are applied to provide free phone (FP) service, credit call (CC) service, and premium rate (PR) service. The service element is implemented, and has a structure for driving an application process capable of providing a corresponding intelligent network service in a basic call processing interface (BCPI) that recognizes a request for an intelligent network service from a communication service user. The initial intelligent network service exchanger was implemented as a toll exchange and does not consider the interaction between the non-intelligent network service and the intelligent network service logic.In the current intelligent network service logic, the interaction between the intelligent network services (FR, CC, PR services) No action is taken into account.

That is, the conventional intelligent network service exchanger does not have an interaction management function between the intelligent network service and the non-intelligent network service, there is a problem that there is no solution to the collision between the intelligent network service and the non-intelligent network service logic.

The purpose of the Advanced Intelligent Network (AIN) is to rapidly introduce various services, and there are a number of features for providing services in an intelligent network environment. The service feature becomes a basic unit of various services provided to service subscribers and network managers. These service features may be combined to form a service or may be independently a unit of service.

Interaction between service features (a sequence of actions that can occur when two or more service logics are activated when a user wants to use a particular service, causing a conflict between these logics) is activated for a call requested by a user. This may occur when two or more of these exist. The Feature Interaction Manager (FIM), which is installed in the Service Switching Point (SSP) of the highly intelligent network, is activated when two or more features of the intelligent network and the non-intelligent network service are activated. The priority of the service logic should be used to manage the invocation of the service logic instance.

The priority mechanism of the service interaction management unit (FIM) is a method of determining priority by interacting with the detection point (DP) processing unit before the service logic program is called, and determining the priority after the service logic program is triggered. However, the present invention is to solve the interaction between the intelligent network service and the non-intelligent network service by applying the former method.

Accordingly, the present invention devised to solve the problems of the prior art and to meet the needs, the service interworking to manage the call between the detection point (DP) processing unit and the intelligent network service and non-intelligent network service logic instance of the advanced intelligent network service switch. An object of the present invention is to provide an interface method between a service interaction manager and a detection point processor that drives a priority mechanism of the action manager.

In order to achieve the above object, the present invention provides a method for interface between a service interaction management unit and a detection point (DP) processing unit in an advanced intelligent network service switch, and the detection point (Arming) when receiving the detection point (DP) information A first step of searching a state table to determine whether arming and a form capable of driving service logic (TDP-R); A second step of transmitting a call progress operation when receiving a detection point DP that is not armed as a result of the determination of the first step; A third step of transmitting a corresponding detection point processing operation when the received detection point is armed but not in a form capable of driving the service logic (EDP-R, EDP-N, TDP-N) as a result of the determination in the first step; step; And if it is armed in a form capable of driving service logic (TDP-R) as a result of the determination in the first step, determine whether the intelligent network service by transmitting a service interaction check request operation and receiving a service interaction check response operation. And a fourth step of processing.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1 is a main intelligent network element to explain the software configuration of the advanced intelligent network service exchanger (SSP) 1 to which the service interaction management unit (FIM) to which the present invention is applied and the operation of the advanced intelligent network service exchanger (SSP). It shows a control system (SCP: Service Control Point) (2) and an intelligent information system (IP: Intelligent Peripheral) (3).

SSP (1) is a bearer resource management unit (4) that provides network access functions to service users, and the International Telecommunication Union-Telecommunication standardization section (ITU-T) BCSM (Basic Call), a standardized basic call state model. The basic call processing unit 5 which advances the call processing requested from the service user by the state model, and the detection point (DP: time generated from the basic call processing unit 5) when control transmission can occur in the basic call and connection processing. Interworking with the detection point (DP) processing unit (6), the service interaction management unit (7), and the service control system (2), which manage interactions between intelligent or non-intelligent network service features. Application process (8) for controlling basic call processing unit (5) to provide the requested intelligent network service to service users, application of advanced intelligent network service exchanger (1) Intelligent network application protocol area (9), intelligent network that forms or decrypts messages so that Seth can send and receive intelligent network operations using intelligent network elements such as service control system (2) or intelligent information providing system (3) and standardized protocols It consists of seven sub-systems of the protocol processing section 10 which provide the communication function between the elements.

The service interaction in the intelligent network can be classified into the interaction between the intelligent network service features and the interaction between the intelligent and non-intelligent network service features. In the present invention, the interaction between the intelligent network service features is the service logic of the service control system 2. It is assumed that the control is performed in the above, and the advanced intelligent network service switch 1 only deals with the interaction between the intelligent network and the non-intelligent network service features.

2 is a flowchart in accordance with the present invention, which is an operational flowchart of the sensor point processor 6 which interacts with the service interaction manager 7 to control the interaction between service features.

In the idle state 21, the advanced intelligent network service exchanger 1 performs an operation (DP_Encountered: basic call processing part) in order for the intelligent network service logic program to control the basic call process of the call requested by the user. In order to report that the detection point of the type has been reached, an operation for transmitting to the detection point processor is transmitted to the detection point DP processor 6 (22). The detection point processing unit 6 receiving the detection point information from the basic call processing unit 5 through the operation DP_Encountered searches the detection point arming state table (23) to indicate that the arming has reached the detection point. It is determined whether or not to report to the service control system (24).

The detection point (DP) can be armed not only for the intelligent service logic but also for the non-intelligent network service logic, and is detected when the non-intelligent network service logic is generated using the service provisioning function to drive the non-intelligent network service logic. By inputting the trigger detection point (TDP: Trigger Detection Point) information in the point (Arming) state table, when the corresponding detection point (DP) occurs, the detection point processing unit 6 is the service interaction of the service interaction management unit 7 The inspection logic can be driven.

If the detection point DP that is not armed is received, the detection point processor 6 instructs the basic call processor 5 to continue the call processing according to the basic call state model. After transmitting the call progress operation, the terminal transitions to the idle state 21 (25).

If the received detection point DP is armed, the received detection point type can drive service logic (TDP-R: A detection point generated by a service provider or a network operator when a new service is introduced into an intelligent network). As a type, after the SSP notifies the SCP of a detection point, it pauses the call processing and receives a response from the SCP, proceeding with call processing under the control of SCP (26) to drive the service logic. (EDP-R: A type of detection point created by requesting the SSP to be notified of the occurrence of a particular BCSM event while the SCP is processing an intelligent network service, after the SSP notifies the SCP of the detection point. In case of receiving a response from SCP after stopping call processing for a while, EDP-N proceeds with call processing under the control of SCP. EDP-N: When new service is introduced into intelligent network, it is generated by service provider or network operator. As a type of detection point, the SSP simply notifies the SCP that the detection point has occurred, and proceeds to call processing. TDP-N: The SSP is sent to the SSP to be notified of the occurrence of a specific BCSM event while the SCP processes the intelligent network service. As a type of detection point created by request, the SSP simply notifies the SCP that the detection point has occurred, and proceeds to call processing, and transmits the corresponding detection point processing operation to the application process 8 before the idle state (21). (27), and when the service logic is armed in a form capable of driving service (TDP-R), the service interaction management unit 7 transmits the service interaction checking request operation shown in Table 1 below (28). Wait for a response from the service interaction manager 7.

The service interaction management unit 7, which has received a service interaction check from the detection point processing unit 6, analyzes the service subscriber information to which the calling party and the called party of the call are subscribed, and the driving service armed with the trigger detection point (TDP). Whether or not there is interaction between service features is indicated by the result of the operation check. If there is an interaction between the service features, the control condition and the control method are used to determine what action to take and transmit the service interaction check response operation of Table 2 to the sensing point processor 6 (29).

The sensing point processor 6 determines whether the driving service is an intelligent network service after encoding the TDP-R operation (30), including the control condition and the control method received from the service interaction manager 7 (30).

If the driving service is a non-intelligent network service, after the TDP-R operation instructs the non-intelligent network service processing unit to drive the requested non-intelligent network service logic, the state transitions to the idle state 21 (32). In the case of an intelligent network service, the application process 8 transitions to the idle state 21 after transmitting the TDP-R operation to request the intelligent network service processing to the service control system 2 (33).

Table 1 shows an operation that the detection point processing unit 6 sends a request to the service interaction management unit 7 to request a service interaction check while performing the TDP-R processing procedure of the service by recognizing the request of the intelligent or non-intelligent network service. It shows the structure of.

Table 2 shows the structure of the operation of checking the interaction between the service features with respect to the call information received by the service interaction management unit 7 and reporting the result to the detection point processing unit 6.

The present invention as described above, as an interface method between the detection point processing unit and the service interaction management unit of the highly intelligent network service switch, by managing the interaction between the intelligent network service and the non-intelligent network service, there is an effect that can prevent the collision between the service logic. .

In addition, the present invention is an essential technology required to develop an initial intelligent network into an advanced intelligent network, and has an effect of quickly introducing various advanced intelligent network services.
