As an access enabling technology, Wi-Fi is already gaining ground in many areas and ‘voice calling’ through Wi-Fi is another area where Wi-Fi holds great potential to entice positive disruption in the telecom space.

With our pre-integrated and modular platform, along with the largest vendor interoperability, Sterlite SMP is capable to support the Wi-Fi calling business segment to the MNOs. We offers a comprehensive service management platform (SMP) for Wi-Fi that enables MNOs to drive a converged solution for Wi-Fi calling. The platform includes converged 3GPP AAA for data and voice services, EAP-SIM/AKA, Non SIM devices authentication, Pre-integrated sigtran stack supporting MAP gateway allows integration with mobile network elements such as the HLR. It also includes Policy control and charging that helps in policy based information fetching and decision making to derive better QoS for the operator. Its Pre-integration enables faster implementation and roll out of services as well as easily cater to varied policy application between IMS and Wi-Fi. With the MNO widely accepting Wi-Fi calling as one of the new revenue generating source, there are few implementation and trials going around with operators worldwide.
