And a caller connected through a public telephone network (PSTN: 130) consisting of a service control system (SCP: 110-1 to 110-n) for data processing and signal processing in conjunction with the SS7 signal network 120; New and various services can be provided between 134 and called party 136. Here, the service management system (100a, 100b) and the service control system (110-1 ~ 110-n) includes a relational database (RDBMS; 102, 112), the service control system (110-1 ~ 110-n) Separate pretreatment systems (FEP: 116a, 116b) are included. In addition, each system installs and operates a subsystem in charge of the function to handle the assigned function. The services provided by the intelligent network system platform include virtual private network service (VPN) and advanced incoming billing service (AFS). , Personal number service (PN), number porting service (NP), card family service (calling card, prepaid card, credit card), and 3rd party billing service.

Referring to FIG. 1, a public telephone network (PSTN) 130 includes an intelligent network switch (SSP: 132), and is connected to an intelligent network system through an SS7 signal network 120, and an intelligent peripheral device (SS7) is connected to the SS7 signal network 120. IP) is connected. The card lookup system 150 is then connected to the Service Control System (SCP) via the X.25 network 140.

The service management system (SMP: 100a, 100b) includes an operation maintenance subsystem (OMS), a service management subsystem (SMS), and a service data processing subsystem (SDPS). The service control system (SCP: 110-1 to 110-n) includes an operation maintenance subsystem (OMS), a service processing subsystem (SLES: Service Logic Execution Subsystem), and a service data management subsystem (SCP). It consists of Service Data Processing Subsystem (SDPS) and Signaling Processing Subsytem (SPS).

A subscriber database, a system management database, and a call ticket database are constructed in the service management system (SMP: 100a, 100b), and a subscriber database is constructed in the service control system (SCP: 110a, 110b).

In addition, although not shown in the drawing, the system management terminal and the service management terminal are connected to the dual LAN bus 104 of the service management system (SMP) to display various information related to system operation and service operation information through a graphical user interface (GUI). This GUI allows the operator or operator to perform operational control and service management. The subscriber management terminal connected to the dual LAN bus 114 of the service control system (SCP) performs functions related to subscriber information such as new generation, deletion, and change of subscriber information of the subscriber. Can be done.

In addition, the service management system (SMP: 100a, 100b) of the intelligent network system is duplicated in a primary / secondary structure, and the service control system (SCP: 110-1 ~ 110-n) is duplicated in an N + 1 structure. Primary / Secondary Structure of SMP System Primary SMP performs service, subscriber management, and billing processing, which are the main functions of SMP system, while Secondary SMP performs the function of Primary SMP when Primary SMP fails. Says to do. SCP's N + 1 structure is to prepare additional equipment to prepare for future failures in the system, and even if one equipment fails, the spare equipment replaces the work of the failed equipment to ensure the performance of the entire system. At this time, the backup system provides a function of load sharing in a steady state.

As described above, the intelligent network system to which the present invention is applied is a load sharing method having an N + 1 structure, and the service control system (SCP) is a post-processing system (110-1 to 110-n) and a preprocessing system (FEP: 116a). , 116b).

This load balance value is determined by considering the status, system status, and system performance of services installed for each SCP in SMP (100a, 100b).

As shown in FIG. 2, the life cycle of the new intelligent network service in the intelligent network system has a life cycle leading to service requirements, analysis / design, service generation, introduction, testing, provision / operation, and removal. Referring to FIG. 2, the intelligent network service is analyzed and designed according to the service requirements, the service is generated, the logic is verified, and the service is tested while introducing the service. If a problem is found as a result of the test, the analysis / design is repeated and the process is repeated. If the test is successful, the service is provided and operated. If the demand for the service disappears, the service is removed. Beginning with creating user requirements for new services as described above, services are created in Service Creation Environmental (SCE), and the generated services are introduced into SMP, SCP, SSP, and IP systems, followed by service testing. Will be provided. In addition, if a service fails during the service test phase after the service is introduced into the intelligent network, or if the user's requirements change, the service life cycle of creating, introducing, testing, and providing the service follows the service analysis and design phase.

The present invention relates to a process of creating a service in such a service life cycle, and the service generation process according to the present invention is illustrated in FIG. 3, in which a user inputs an SIB chain (S1) and a state transition table ( generating a state transition table (S2), and generating a service logic program (S3). The service creation environment of the intelligent network provides a function of analyzing a service requirement of a user, creating and verifying a service, and installing a service through interaction with a service management system (SMP). The result produced by such a service generation environment is service logic for service control system (SCP) and service management system (SMP), service data template, service trigger information, and the like.

Service creation in the service development environment is divided into service description, service design, service development, service verification, and service administration. The service creation tool implements some of the essential functions of the service development environment. The main function is to obtain a service logic program as a product by using the SIB operation chain as input, and implement a partial function of the service development environment. This is to improve the service creation process more efficiently and reduce the error of the creator. In particular, it provides service design and service development functions among the functions of the service development environment, and provides functions related to logic generation necessary for service creation and testing. Service logic programs can be generated, modified and supplemented quickly based on the service specification results. That is, in the process of designing and generating the service logic program, the SIB operation chain 401 and each SIB parameter 402 shown in the service specification are inputted and the state transition table as an intermediate step for generating the service logic program is generated. Convert to form Then, information such as call context information, service instance data, call ticket, etc. are extracted from the input. Based on a variety of information, it is converted into a service logic program format to generate a binary file that can be executed by a service control system (SCP). And if you want to modify the service logic program that you have already created, support for modifying SIB parameter and chain.

4 is a diagram illustrating input and output of a service generation tool according to the present invention.

Referring to FIG. 4, the service generation tool 410 receives a SIB operation chain 401, a SIB operation parameter 402, and a call ticket information 403, and receives a SIB operation logical end template 411. ), An action / event / state list (412: Action / Event / State List), an SIB operation parameter template (413: SIB op parameter template), and the like, after creating an intermediate step, and using the service logic program (421: SLP). And a call context (422), a service instance data (423), a call ticket (424) and the like as outputs.

In this way, the SIB structure, which is the center of input of service logic generation, is as follows. According to the ITU-T CS-2 Recommendation, SIB is a reusable network-wide capability consisting of SIB operations, and SIB operations are defined as a function that can no longer be broken down. The SIBs supported by the service creation tool 410 according to the embodiment of the present invention follow the structure of the ITU-T Recommendation CS-2 (Q.1223, Q.1224), and define 19 SIBs through slight modifications and additions. And 40 SIB operations constituting them.

The structure of the service logic program generated according to the present invention is a state transition table representing a state of a call as a state transition as shown in FIG. 5, and an action defined when an event occurs in a state. ), Transitions to the next state, and waits for the next event.

Referring to FIG. 5, a state is a one-dimensional array having pointers to action nodes for events that may occur in each state, and each node has an action, an event, and a next. It has a pointer to a state. That is, state 0 has a pointer to action 1, action 1 has a pointer to action 2, action 2 has a pointer to action 3, and each node It contains pointers to the following nodes: State 1 has a pointer to action 5, and action 5 node has a pointer to action 6 node. In the same way, states 0 through 7 each have pointers to the corresponding nodes of actions 1 through 20, respectively, and each of the nodes involved is linked to each other.

As such, during the service creation process, the SIB chain, which is an input of the service creation tool, is converted into a state transition table composed of states, actions, and events in the service creation tool. That is, the SIB becomes a source of actions and events that are components of the state transition table. Here, the action is the minimum functional unit provided to perform the service logic in the service control system (SCP), the event may occur outside and inside the service generation system, and determine the flow of the service logic. It is an element. Internal events are mapped to the logical end of the SIB, and external events are those that can be generated by interaction with the user.

As described above, according to the present invention, when a new intelligent network service is to be introduced, the service can be introduced quickly by automatically generating a service logic program and related data for analyzing the user's requirements and providing the service. It has an effect.
