Real-time protocol translation and NGIN at Orange Poland
Orange Poland and its mother company Telekomunikacja Polska were early pioneers in the deployment of IN platforms. Like many early adopters of “IN”, they built and deployed numerous vertical VAS platforms involving multiple technologies and different vendors.
In 2010, as part of Orange Group’s platform consolidation initiative, Orange Poland management decided to replace and migrate some of its more costly and/or obsolete VAS platforms to modern technology platforms.
The key challenge facing Orange Poland concerned their core fixed-line SS7 protocol. This was a national variant of INAP (Capability Set 1), known as TP-INAP, which has a limited and basic feature set. This meant that more advanced telecom services, such as multiple leg services, were not possible. The central challenge was how to introduce a more feature-rich protocol and therefore enable more advanced services without necessitating the wholesale upgrade of multiple network elements.
Orange Poland architects designed a solution which specified a high performance, highly reliability component that would act as a proxy in the network and mediate between different network elements using the requisite protocols. This meant that the majority of systems could remain untouched and using TP-INAP. The solution Orange designed required a Service Control Point (SCP) hosting the protocol proxy application between the Service Switching Point (SSP) and the VAS platforms.
The proxy application acts as an SCP in the integration with the network SSP. The proxy application acts as an SSP in the integration with 3rd party VAS platforms.
Having decided on the architectural solution, Orange Poland evaluated the market for suitable products to host the solution. The solution required:
- Real-time protocol conversion
- The ability to support INAP CS1, TP-INAP and Orange’s selected multi-leg protocol (Siemens INAP – SINAP7)
- Support for IP related operations was also required
- A reliable, high performance and fault tolerant platform
- Open platform that allows Orange to develop their required functionality and to use their own R&D resources
Orange Poland selected the OpenCloud Rhino platform. The platform was procured and the solution built over a 3 month period.
Today, OpenCloud Rhino is been deployed in one of the mission-critical parts of Orange Poland’s network, in the frontier of the Core Network and the Service Layer, and serves over 14 Million subscribers. The deployment is a strong endorsement from Orange group on OpenCloud’s ability build a true carrier grade Telecom Application Server.
