IMS Breakout Gateway Control Function (BGCF) Routing Server

The BGCF element plays an important role in IP Multimedia Subsystem (IMS) networks as a SIP proxy to route calls between IMS and non-IMS networks. Through a special software pack, the Sonus PSX Centralized Policy and Routing Server can be upgraded and deployed as a fully functional BGCF routing server. The Sonus BGCF routing server is a transaction-stateful SIP proxy server that delivers everything you would expect in a BGCF device, including high performance, 3GPP R9 compliance and complete support for IMS ecosystem elements via Mi, Mj, Mk and Mx interfaces. In addition, the Sonus BGCF includes many value-added features not found in other BGCF servers, such as Next-Generation and SS7 Service Control Point (SCP) lookups, DNS/ENUM server overload controls and Address Reachability Service (ARS) controls.

    Sonus Case Study: Wireless-Wireline Communications Company & Sonus BGCF Routing Server

    Shifting market demands from wireline to wireless and 3G to 4G leaves many network elements, systems and infrastructures in one part of the network underutilized while positioning others in a chronic state of overutilization. Managing an effi cient network transition requires architectural fl exibility through elements that can combine both legacy and next-generation functions.

  • The Sonus IMS Solution

    Sonus IMS Product Portfolio is delivered using field-proven functional components that have matured in real commercial deployments. As the company that adopted SIP over a decade ago, and has led the world in carrying IP-voice LD traffic, you can expect a deep understanding of the signaling interworking, and carrier class reliability that is required to deliver an IMS product. Each of the IMS functional components is supported on one or more of the Sonus products, as shown below. Some of the functions such as the CSCF, BCF and BGF are delivered using our purpose built ConnexIP® platform that helps the IMS solution scale linearly and cost-effectively, while providing value from day one. Some of the other functions leverage Sonus' existing product lines such as the GSX9000, SGX4000 and the PSX Centralized Route Server. This is further enhanced by a healthy eco-system of third party client and solution providers that help deliver an end-to-end value proposition and a turn-key solution.

  • Sonus Breakout Gateway Control Function (BGCF) Routing Server

    In the years to come, IP Multimedia Subsystem (IMS) networks will need to interoperate with both the PSTN and circuit-based GSM and CDMA wireless networks. The Breakout Gateway Control Function (BGCF) provides a bridge between those networks by determining where and how to route calls from IMS networks to circuit-based networks. The BGCF Routing Server from Sonus Networks provides a best-in-class IMS breakout gateway with extra features that go beyond standard BGCF functionality to deliver even more value to IMS networks. Based on the Centralized Policy Server, the BGCF Routing Server provides a centralized, scalable solution for routing calls between IMS and circuit-switched networks that leverages years of experience in IP packet-to-circuit interoperability.
