Abstract: A new valueadded service creation pattern for convergence network, capability injection (CI), is presented. The resourceoriented architecture model is adopted in the CI pattern to abstract network capabilities into resources, thus the unified resource control could be used for capability control, while in traditional service creation, different interfaces and different invocation rules would lead to different state control process. Therefore, value added service creation is greatly simplified, and the flexibility, the extensibility and the security of value added service creation in web 2.0 environment are enhanced. Applications in China telecom short message value added service systems verify the feasibility of this pattern.

Key words: web2.0, representational state transfer, service-oriented architecture, resource-oriented architecture
