Virtual Home Environment (VHE)

TOMIA’s VHE services enable operators to complete roaming calls and ensure that their subscribers benefit from the best user experience while roaming.

Market Challenges

Once abroad, travelers often face dialing obstacles, such as unfamiliarity with the visited network dialing formats, prefixes, and local languages.

QoS

Roam-Like-At-Home regulations that define wholesale cap charges have significantly impacted margins. On the other hand, it has boosted usage. Consumption habits are also changing, with many users opting for voice apps like OTT instead of traditional voice communication. Operators are under pressure to deliver better financial results and the best roaming experience to ensure their position in the mobile communication value chain.

Unlike traditional CS (Circuit Switch) voice, VoLTE calls are routed back home. The home network is unable to resolve local calls if they are dialed without the international prefix. This can drastically affect the satisfaction of unaware outbound roamers as they can experience different behaviors for the same call depending on whether they are roaming on a VoLTE or non-VoLTE network.

When roaming, subscribers can’t access the value-added services they enjoy when at home such as: voice mail or toll-free numbers, if no translation to the international number is available. To address this requirement, network operation teams need to constantly track and provision frequent worldwide numbering plan changes. However, network nodes are not designed to cover the underlying complexity, and any missing information can cause degraded QoS and a reduced call completion rate.
