MVNOs Can Lower Fixed Operating Costs with Modulo’s GMSC

Many of today’s “light” MVNOs are highly dependent upon a backing MNO for services such as call routing. Because of this dependency, MVNOs can’t choose the most profitable routes for their network, and they incur high fixed costs for routing calls outside their network.

Due to the high costs of inter-network call routing, Mobile Telephony ROI highly depends on the routes that Voice calls take from the operator’s network to other mobile networks. The choosing of custom, cheap or high-quality routes to complete calls is a key element in determining a Mobile Operator’s profitability.

For MVNOs looking to expand from a light MVNO to a full MVNO setup, the upgrade entails deploying a Gateway MSC. The Gateway Mobile Switching Center (GMSC) is a special kind of MSC that is used to route calls outside the mobile network. Whenever a call for a mobile subscriber comes from outside the mobile network; or whenever the subscriber wants to make a call to somebody outside the mobile network – the call will be routed through the GMSC.

When an MVNO has its own GMSC, it can set up route agreements with peer network operators that are more profitable than the ones used by its backing MNO. Lowering routing costs this way can significantly increase the MVNO’s ROI and overall profitability.

Modulo’s GMSC is a highly scalable, versatile, cost-effective solution that allows even small-scale MVNOs to enjoy call-routing independence. Our product is built around the Telcobridges TMG series Class 4 Switch, leveraging its features to seamlessly route calls to/from protocols such as ISUP, ISDN, CAS and all types of SIP. By using Telcobridges’ TMG series, our GMSC allows operators to connect to any type of technology that has been available for the last 30 years for carrying voice calls.

Modulo’s GMSC also allows offline and real-time charging: It allows creating a call data record for each call that can be processed by a billing server, or connecting to a 3rd party billing server via a real-time protocol (such as RADIUS or DIAMETER) in order to make decisions on call routing and accounting.
