C3 Call Session Controller

IMS Mgcf, media gateway controller

Today’s operators are seeking market-proven, intelligent platforms that can interwork multiple network types, signaling, and protocols in order to offer high value, revenue-generating services.  The C3™ Call Session Controller, part of GENBAND’s call controller portfolio of innovative transformation products, is an intelligent multi-application call server and media server/media gateway control platform for IMS deployments.

Deployed globally in the smart cores of many operator networks, the C3 provides service convergence and feature transparency across a wide range of wireless, wireline, TDM, and IP networks. Solutions supported by the C3 include IPX, Peering, Intra-Network Interconnect, MGCF, MRFC, Gateway MSC, and IP Transcoding and Media Adaptation.

The highly-scalable C3 operates in small, large, and geo-redundant configurations to millions of Busy Hour Call Attempts. Operators can grow capacity as needed by simply adding pairs of C3 nodes to a deployed system.

The C3 integrates call session control, media gateway and media server control, service logic, billing, regulatory, signaling, service creation, and element management within a common, scalable software and hardware environment, reducing the need to deploy costly additional platforms. It provides open, standard access and trunking interfaces for signaling, management, and line equipment/CPE, including SIP, SIP-I, SIP-T, H.248, H.323, PRI, SIGTRAN, CAS/R2, SS7/C7, BICC, IS-41 and SS7/AIN/IN, as well as a wide variety of country-specific variants.

IMS MGCF and MRFC

Operators can seamlessly evolve into IMS MGCF and MRFC elements, and transform GENBAND’s media gateways with call controllers into access or interconnect media plane elements, thus ensuring both investment protection and service transparency.
