With the "land-grab" of mobile subscriber acquisition largely over, mobile operators are looking to substitute fixed and broadband telephony usage. Fixed providers are fighting back with the advent of a lower cost, IP-based infrastructure complemented by multi-access communication services – services which are available when away from the office or home through WiFi, WiMax, femto-cells and other fixed radio-access networks. Mobile is going fixed just as fixed is becoming more mobile. For all types of operator, the core challenge is the same: how to transition from the existing TDM SS7-based network technologies that are used widely today to a common IP-based core network. With most subscribers using the existing infrastructure, operators have to transition their infrastructure whilst keeping their customers happy.

JSLEE-based Application Servers are uniquely placed to help operators meet this challenge. Unlike other technologies, Rhino Application Server is designed:

• To provide an asynchronous, event-driven paradigm essential for person to person communications protocols
• To meet the stringent availability, latency and volume characteristics of telecommunications service layer equipment
• To provide full native support for all networks and protocols – today’s predominant SS7 and IP-based networks
• To provide an extensible, pluggable “Resource Adapter” architecture so that additional proprietary & standards-based protocols can be added
• For real-time charging of telecommunication services
• To provides a Java-based OO development environment which facilitates efficient creation of protocol variants by re-using proven components
• To provides a rich set of service run-time capabilities for telecommunications in-network protocols & services, such as concurrency control and asynchronous event handling
• To implement a robust & coherent failure model which is applied to all hosted services
• To enable the use of commercial-off-the-shelf hardware, OS and software platform within the service layer of the network
• To comply with an open standard that was specified for the purpose and is actively developed by a community of interested parties rather than a proprietary initiative

OpenCloud Rhino and FMC

With OpenCloud Rhino, fixed, mobile and hybrid telecommunications operators can provide services to users irrespective of their location, access technology, and terminal. Rhino Application Server enables service convergence ahead of the underlying and gradual network convergence. Simple “intelligent network” services such a single voice-mail system across mobile, fixed line, Internet etc. become very straight forward. Targeted, personalized and configurable services that fit specific customer needs can be conceived and realized today ahead of the universal IP connected world of tomorrow.
