The present invention relates to a SIB type conversion method for converting SIBs by type to automatically generate intelligent network service logic in a service development environment (SCE).

The concept of Service Creation Environment (SCE) has emerged for the rapid creation and introduction of intelligent network services. In a service development environment, a service designer describes a service by combining standardized parts that abstractly express the network's capabilities. The automation tool automatically generates a service logic program that can be executed on an intelligent network platform.

In the service development environment to which the present invention is applied, a three-step process is performed to generate intelligent network service logic.

When a user describes a new service by combining a Service Independent Building Block (SIB), which is a service-independent building block, the SIB combination is transformed into service logic, which is intermediate code that is independent of the target platform, and the intermediate code runs back on the target platform. It is converted into a service logic program (SLP).

Translating the abstraction of the SIB, which abstractly represents the user's desired service, into intermediate code that contains specific information, such as the flow of messages between functional entities, requires a great deal of effort.

Once the intermediate code is generated, converting it to a service logic program running on the target platform only requires a simple effort, such as adjusting the target's dependency information or an application programming interface (API).

To help translate from the current SIB combination to intermediate code, which is at the level of distributed service logic, the International Telecommunication Union (ITU-T), the Distributed Functional Plane for the Capability Set-1 (CS-1) SIB. Plane specification was recommended.

However, in the case of automatic conversion based on the recommendation, each of the SIBs correspond one-to-one to the distributed functional plane, but there are various problems when the SIB combination is to be converted into the distributed functional plane.

In other words, when automatically converting a combination of CS-1 SIBs, most of the SIBs correspond to one-to-one specification of the distributed functional plane, but some SIBs correspond to the distributed functional plane divided into several sequences.

In particular, it's hard to make automatic conversions because it's only possible to know how each sequence is distributed at run time. In addition, in the specification of distributed functional planes corresponding to some SIBs, there is a part of connecting to and disconnecting from an intelligent peripheral (IP) every time, and the service logic that is the result of the automatic conversion has a problem of optimization violation. have.

Accordingly, the present invention devised to solve the above problems is to classify and convert the SIB into three types in order to facilitate automatic conversion when the CS-1 SIB combination is automatically converted to intermediate codes of the distributed service logic level. The purpose is to provide a conversion method by type.

In order to achieve the above object, the present invention, in the conversion method for each type of Service Independent Building Block (SIB) applied to the converter of the service development environment (SCE), the SIB type is investigated based on the information extracted after the SIB information is cold The first step to do; A second step of recording a specification of a distributed functional plane in a main process file if the SIB type is unity as a result of the first step investigation; A third step of recording the first single unit of the specification of the distributed functional plane in the main process file and the remaining single unit in the subprocess file if the SIB type is non-uniform as a result of the investigation in the first step; And the SIB type SIB-type SIB, the SIB-type SIB of the distributed functional plane is recorded after recording a single unit related to the IP connection of the standard of the distributed functional plane in the main process file only when IP connection is required. And a fourth step of recording a single unit related to the main function of the main process file and recording a single unit related to the IP release of the standard of the distributed functional plane into the main process file only when IP access is required. It is done.

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

It is composed of a SIB converter 22.

The SIB searcher 221 extracts the SIB name (SIB_identifier), the SIB type (SIB_type), the SIB parameter, and the like from the SIB and passes the result to the SIB converter 22. The SIB converter 22 first reads the distributed functional plane specification corresponding to the SIB name from the distributed functional plane specification base 23, and records the specifications of the distributed functional plane read according to the SIB type in the service logic file.

Service logic files include a main_process file with service logic executed in the main process and an aux_process file with service logic executed in the secondary process.

It stores the distributed functional plane specification that corresponds to the SIB (type0) with unity. The distributed functional plane specification corresponding to SIB (type0) with unity consists of one single unit. The specification of the distributed functional plane corresponding to the non-uniformity SIB (type1) is stored separately in several single units.
