in Blog, VoLTE, LTE

The GSMA recently announced that it has adopted the work of the One Voice Initiative to drive a standard way of delivering voice and messaging services for Long-Term Evolution (LTE). According to GSMA, it’s Voice over LTE (VoLTE) initiative has the backing of more than 40 organizations including many of the world’s leading mobile operators, handset manufacturers and equipment vendors.

These leading organizations support the principle of a single, IMS-based voice solution for next-generation Mobile Broadband networks. The GSMA is expected to lead the development of the specifications that will enable interconnection and international roaming between LTE networks, and it will be complete by Q1 2011.

For LTE to support voice and messaging, an IP-based solution is required that will offer the same interoperable and seamless experience that 2G and 3G wireless technologies offer today. IMS (IP multimedia subsystem) can achieve this, and supports all voice call service features such as call waiting, call hold and call barring, and is highly scalable to serve very large subscriber bases.
