Roaming revenues have been declining for several years now, and some CSP’s have realised that being accepted as a preferred roaming partner in their home country can generate important revenue to replace that lost through declining outbound roaming settlements.

A HPMN will normally have a choice of several VPMN’s in most countries their customers will roam to, and they have the ability to steer their customers towards a preferred VPMN when roaming. The decision on which roaming partner will be selected as their preferred VPMN will be based on a number of factors, for example NRTRDE compliance, network quality, inter-operator tariff (IOT) discount agreements, etc.

In most countries now, the services provided by all VPMN’s is reasonably consistent, so a service differentiator should be explored to provide an additional level of service not offered by the other in-country CSP’s. A relatively simple value add is to evaluate NRTRDE-OUT records for visiting roamers and provide immediate advice to the home network of any obvious fraud or misuse. While it is accepted that (in most cases) NRTRDE records will be delivered to the home network within 60-90 minutes, the earlier suspicious activity is notified, the sooner financial loss can be avoided.

The opportunity to add value in this way will be limited as more operators implement VoLTE. Since VoLTE is an all IP Network, the VPMN has no visibility of voice traffic originated via S8HR VoLTE roaming. While there are only an estimated 600 operators currently fully operational with VoLTE, it will take some years before there is a full transition from Circuit Switched (CS) to VoLTE.

Offering roaming partners some additional value now by reviewing their NRTRDE-OUT records is a sound strategic move to establish a trusted relationship which could then continue as the networks transition from CS to VoLTE and secure ongoing roaming revenues.
