This is Part II of Peter Nas’ Blog Entry: Other DRA added-value in VoLTE
There’s additional value to the fundamental session binding functionality of a DRA. A DRA can enable optimal call management ensuring higher quality-of-service VoLTE calls. For instance, think of all the different vendors’ equipment that is needed to exchange Diameter Gx and Rx signaling. One example is when the LTE PGW has a different Gx implementation than the PCRF. In turn that PCRF can have a different Diameter Rx implementation than the IMS’s P-CSCF node. Typically inside an operator’s network, there will be various vendors for LTE, PCRF and IMS core network elements. And this is the norm in roaming use cases where the visited LTE network is out of control (meaning a different vendor) than the home IMS network, where the P-CSCF (and other elements) will be involved.

Operators have begun to get more and more serious around deploying VoLTE (Voice over LTE) in their networks. Since the announcements of VoLTE services from some Korean and US operators, others, particularly in Asia, North America and EMEA, have launched or are about to launch VoLTE (see GSA announcement of 17th Sep 2014: 71 operators in 36 countries investing in VoLTE deployments, studies or trials, 10 operators commercially launched HD voice using VoLTE). More often than not, operators use a Diameter Routing Agent (DRA) to support correct routing and control of the Diameter signaling related to VoLTE.

The market is changing rapidly, with new applications and usage models appearing daily. LTE is a major driving force in this change by providing reliable high bandwidth to mobile devices.
The cost of that ubiquitous bandwidth is falling with the realizing of NFV and SDN technology, further pushing down the cost per megabit delivered to the end customer.
This is all great news for the industry, more bandwidth, more users, more apps, new devices, higher quality connections, video support. What’s not to like?

Plenty of service providers (and their end-customers) have jumped on the 4G LTE bandwagon. As a result, two of the most immediate and noticeable changes we are seeing are the speed at which data services are running and high-definition voice quality.
And that’s great…assuming that everything works as it should, and customers receive the quality of experience they were promised. But sadly, many 4G LTE implementations do not live up to expectations due to the challenges that lie within the core elements of these networks.
