Thanks to i-RPS, the Service Provider overcomes fragmentary and meshed approaches building an optimized transit layer in heterogeneous network domains (NGN, IMS, PSTN, PLMN).
The first goal of the Service Provider was the replacement of Cisco PGW-based Class 4 Platform in the fixed network.
Italtel supported the migration of all interfaces, traffic and services from the Cisco PGW Softswitch towards the new Routing Server i-RPS. For this reason, i-RPS has been integrated with the fixed network environment, previously provided by Italtel.
i-RPS enables new services and business opportunities, thanks to Number Portability and centralized Emergency Calls management.
It provides multi-homing ensuring local high availability and geographical redundancy
Up to 500.000 sessions and 5.000 call per second
More than 700 domains configured
80 Millions of CDR per day
10 Millions of DB records for Emergency Calls
OPEX AND CAPEX REDUCTION
Single point of provisioning for the traffic routing among different networks, allowing centralized managed policy and routing databases without the need to apply changes in all the different network nodes
Real-time routing updates with easy and faster network routing modification and roll out of new services
Access to a single system featuring at the same time multi-protocol access, Number Portability DataBase, Emergency Calls DataBase and service brokering
Easy to insert new interconnections, allowing a simple migration path from TDM to IP and to dismiss legacy equipments also with a significant operative cost saving
Complete support of the very complex routing functionality (e.g. overlap, dialing and numbering plans, various business needs, originating carrier and trunk groups, charges, codecs, digits, NOA)
ADAPTABILITY AND TRANSPARENCY
The centralized function capable of collecting and computing the network data, providing routing and policies based on the Service Provider’s requirements, allows time-to-market differentiating services necessary to lead the communications market
No need to validate in-switch equipment (including SBCs) for any routing evolution
Complete control of calls avoids the presence of SBCs for traffic between different networks
FUTURE PROOF APPROACH
Powerful number analysis and routing capabilities combined with complex service logics allow to easily follow the evolution on both commercial and regulatory sides
Evolution to a dedicated IP-IP interconnection infrastructure with National and International Operators
FLEXIBILITY AND SCALABILITY
Single point of access to the overall routing, traffic engineering and policy management
Centralized routing configuration throughout the network
Choice of the most cost-effective traffic routes (and relevant daily changes) for long distance interconnection and wholesale traffic
Traffic routing optimization inside the network
Support of all the protocol stacks and features, allowing the control of the previous installed systems to guarantee a smooth migration of a multi-technology network towards a homogeneous IMS one.
i-RPS is deployed on virtualized environment using Cisco UCS hardware as physical environment with VMWare hypervisor.
i-RPS acts as:
Centralized routing node
Number Portability DataBase
Emergency call DataBase
Among the several signalling protocols and contexts, in this deployment i-RPS mainly supports the SIP based subscribers and interconnect environment and it interworks with the legacy TDM environment.
To complete the Centralized Routing solution, Italtel also provided the Element Manager i-NEM on the same virtualized platform. i-NEM is a multi-network element manager and it is able to manage the MGCF as well.
In details, Italtel installed two i-RPS nodes in two different regions, in dual-homing configuration with a single point of provisioning of a Centralized Routing Solution to manage these scenarios:
SIP proxy interconnections towards all platforms acting as SIP gateway, through SBCs with OLOs and direct with legacy, IMS/VoLTE and Mobile network
INAP connection to legacy platforms to provide homogenous routing policy.
Italtel, thanks to its own experience in communication networks, helps the service providers to have an immediate benefit in the solution of a problem with a platform that facilitates the network transformation process and to ensure a better time-to-market in the development of new business opportunities.
