Now that LTE networks have been rolled out by most of the service providers in the world, the next objective for operators is the migration of the voice service to the LTE network. This migration is known as Voice over LTE or VoLTE.
VoLTE brings the two sides of the same coin. On the one hand, VoLTE is bringing multiple benefits for service providers (spectrum efficiency, high quality voice, OPEX & CAPEX reduction, etc) but on the other hand, VoLTE service is also bringing some challenges. Those challenges have an special impact on the Policy Management solutions currently deployed for Data Services as this node becomes a critical node in the network for VoLTE.
Policy Management plays a significant role in VoLTE and becomes a mandatory node in the network. This node is responsible for establishing and releasing, on behalf of the IMS domain, the bearer required to accommodate voice traffic.
Additionally, VoLTE is defining some stringent requirements for Policy Management solutions.
This week I spoke at the Policy Control 2014 conference in Berlin on VoLTE, a Game Changer for Policy. Find out more information on Cisco’s Quantum Policy Suite for mobile: http://www.cisco.com/c/en/us/products/wireless/quantum-policy-suite-mobile/index.html .
