Diameter in custom applications

+1 vote
75 views

One observation from our deployments: Apart from 3GPP standard interfaces, we see many vendors using Diameter for custom applications. Two examples: A security platform vendor uses Diameter accounting application (CCR/CCA) to communicate SMS data (and metadata) between the network and the platform. Another SP is using ETSI E2 to exchange user related information between P-CSCF and a dedicated server.

Reasons are obvious:

  • Diameter being extensible, it is easy to develop custom extensions.
  • Protocol is already in the network, so doesn't add additional complexity
  • Network has the tools and mechanism to manage Diameter traffic.

If this interests you, we have a case study on such a deployment: http://www.lcnpl.com
