2Service engineeringService engineering can be defined as the set of methods, techniques and tools to specify, design, implement, verify and validate value added services that meet user needs and deploy and exploit these services in the current or future networks. Develop scientifically-based design principles and tools (software) that support the balance of service quality, process efficiency and business profitability, from the views of customers, servers and managers.3Service engineeringThe process of developing services for reuse in service-oriented applicationsThe service has to be designed as a reusable abstraction that can be used in different systemsInvolvesService candidate identificationService designService implementation

APICSCE13Background and related worksThe standardization of open API at the network level was initiated by the Parlay group in 1998Parlay X APIs , based on web services technology, are very simple, easy, and Internet-friendly.

16Background and related worksThe service description function in SCE is generally realized by the combination of standardized and modularized building blocks such as SIBs (Service Independent Building Blocks) that represent the capabilities of the network in an abstract way. Besides, the SCE can support a visual programming environment for service designers to combine the SIBs easilySCESIBSIB17Background and related works

18Background and related worksSoftware Development Kit (SDK), which can provide open APIs as components integrated into commercial Integrated Development Environment (IDE) such as MS.Net Studio, JBuilder x, Bea Web Logic Studio, etc.Ericsson SCE offers Parlay APIs which can be used only for a Java system, and it is designed to adapt only Ericsson NRG (Network Resource Gateway). If there are changes in the gateway system, Ericsson SCE cannot be adapted on it.APINETJBUILDERBEA WEB LOGIC STUDIOEricssonSCEParlay APIJavaEricssonGatewayGateway
