Many applications are exposed as Web Services deployed in web servers. We use BPEL to orchestrate these services to provide new services. This way works very well if there are only Internet services. But if there are telegraphic services it becomes slower. In this paper we present a detailed analysis of an enhanced JBI architecture in which a JAIN/SLEE service engine has been seamlessly integrated. With BPEL engine and JAIN/SLEE service engine we are capable to orchestrate service entities from both telecom and IT domains. JAIN/SLEE service engine which is driven by events, contains all the atomic business services. To orchestrate these atomic services, we design a business BPEL process and deploy it to BPEL execution engine. The orchestrated execution environment is capable of integrating the business in both Internet field and Telecommunication field.
