基于SIP构件和web service的电信业务的设计与实现

he next-generation network is a service-driven network. Users have high requirements on the diversification of the business. Developing diverse service quickly and efficiently is the key to the next generation network service creation. Through comparing to the existing service development model, this paper proposes a combination of SIP component of BPEL-based extensions and web service to develop telecommunication service. The model combines the quickness of component development with the diversity and richness of web service. It encapsulates individual functional modules, provides greater granularity of service abstraction, improves the diversity of business integration, and simplifies the service development.
