Ribbon's IMS Solution
So in terms of the IMS Network, the whole transition from 2G to 3G to LTE happened over time. And if you just look at the voice set of things when it was 2G and 3G the voice was really a separate component and it was not merged in with the data. The data used to go in a separate channel and voice was in a separate channel and it wasn’t good spectral efficiency because they were using different spectrums. But with LTE, the data and voice are combined into one IP infrastructure and it saves Service Providers money because of the shared spectrum. For the end-user, they can get to see new services like high-quality voice. But the key point of LTE is that data and voice are on the same IP network.
When voice rides on LTE, which is voice over LTE, there is an IMS Network that sits behind the RAN (Radio Access Network) that really deals with voice and there are different components of IMS. But from a high level, there is an axis side of IMS, there is peering side of IMS (that you peer to other networks, and then there is the analytic side or the operation side of IMS.
Ribbon plays at the edge of the IMS Network, on the access side from subscribers and is on the peering side with other networks. Ribbon plays at the edge of the network, which is where you need security, interworking because different IMS networks are different. You need roaming capabilities for when calls roam from one network to another and you need things like emergency calls, which is key to any network.
If you look at the different components of IMS, and these are the layered Ribbon elements that correspond to those IMS elements. The Ribbon SBC plays multiple roles in IMS Network. It can play and Access Gateway role and play a proxy CSCF function, an IBCF function (which is more on the peering side), or a Transit Gateway function. The SBC takes on different roles based on the different components of the IMS architecture. Ribbon’s SBC acts mostly on the access and the peering side of things from a security interworking perspective.
Ribbon’s PSX is our centralized routing engine that plays the role of a BGCF (Breakout Gateway Control Function), so when calls have to leave the IMS network go to a different IMS network or break out the PSTN then use a function called the BGCF and the PSX plays that role. Ribbon’s C3 Gateway Controler and G9 Gateway function that map to the MGCF and MGW functions with IMS. The key point we have products for the edge of the network where you need security, scalability, interworking as the key aspects of the IMS capabilities.
Ribbon’s Analytic solution comes in and provides the overarching solution. It helps with troubleshooting, provides security visibility and helps provide monetization; all of these components cover the entire IMS architecture. Ribbon’s Virtual Mobile Core functions as an Application Server from a session continuity perspective. These are the different elements that form the core of the Ribbon solution when it comes to IMS.
This webinar goes into detail on how our SBC and PSX help and support security in the peering, access, and roaming sections of the network.
