A roaming gateway has at least one IP network interface, and at least one cellular network interface, and inter-working functions for inter-working between a wireless IP network and a cellular network. The inter-working functions communicate with user devices in an IP network according to a machine-level subscribe-and-notify event package protocol for managing handover of mobile devices roaming between IP and cellular networks. They also poll a cellular network for subscriber status on that cellular network in the absence of a mobility event package. The inter-working functions comprise HSS functionality programmed to access data on a HLR of a cellular network and to perform HSS operations using said data. The gateway applies routing policies specific to call types, allowing or disallowing the anchoring of calls originating in either an IP network or a cellular network based on number prefixes. The inter-working functions comprise an application server programmed to communicate with a user device as a client. The server provides a staging point for cellular supplementary services while anchoring calls, retrieving configurations from cellular network elements and applying appropriate routing based on these configurations and the current state of a call.

Roaming gateway

A work flow manager () of a gateway comprises a process automation component (), a policy engine (), and a traffic gateway (). The work flow manager () communicates via the internet () over IP with content providers () and content aggregators (). 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 () including mobile network SMSCs, MMSCs and IMSs (IP Multi-Media Sub-systems). The process automation component () 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 () which implement the process. The policy engine () interprets the BPEL to provide lower-level policy enforcement work, flows in a policy enforcement execution language (PEEL). The traffic gateway () 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 gateway
