Inter-MSC Trunking

GENBAND's Inter-MSC Trunking solution uses the advanced routing and transport features of the GENBAND C3 Gateway Controller and G9 Converged Gateway to migrate the core of today's mobile voice network from TDM to VoIP.

Mobile operators are under continuing pressure to decrease their network costs by improving network efficiencies. A significant portion of these costs are incurred in their core networks, which are often comprised of a mesh of circuit switched trunks. These trunks are leased or owned facilities between MSCs in a city or between city or even country locations. At the same time, many mobile operators are using a parallel IP network for their data traffic.

GENBAND's field-proven C3 and G9 platforms eliminate costly TDM trunks in the mobile core, using the IP network for voice transport. An advanced softswitch for mobile networks, the C3 platform’s geographically redundant, carrier grade architecture enables operators to start with small networks and expand to support millions of calls across a continent. A wide range of IP and TDM network interfaces, protocols and codecs are supported for flexible and cost-effective network deployments.

Mobile operators can simultaneously use the same G9 platform as an R4/LMSD mobile access gateway, enabling immediate additional cost savings in the mobile core. The platforms also provide IP tandem and international gateway services, enabling mobile operators to deploy multiple applications using a single network system, simplifying network operations and lowering total cost of ownership.
