ABSTRACT:
A work flow manager (1) of a gateway comprises a process automation component (2), a policy engine (3), and a traffic gateway (4). The work flow manager (1) communicates via the internet (5) over IP with content providers (6) and content aggregators (7). On the other side it communicates over the Internet or over a private IP network, using diverse proprietary and known protocols with service enabler resources (20) including mobile network SMSCs, MMSCs and IMSs (IP Multi-Media Sub-systems). The process automation component (2) presents a GUI to generate a work flow definition in a high level business process execution language (BPEL), with interaction with the service enabler resources (20) which implement the process. The policy engine (3) interprets the BPEL to provide lower-level policy enforcement work, flows in a policy enforcement execution language (PEEL). The traffic gateway (4) interprets the PEEL to provide a low level language (traffic policy execution language, TPEL) for high performance implementation of steps of the work flow process. PRP means Policy Request Protocol, a lightweight protocol for AAA request/responses within the gateway1.
