ZTE and Telefónica del Perú have built first IP multimedia subsystem voice over long-term evolution (IMS VoLTE) network in Perú and in Telefónica LATAM. They have built a unified fixed-mobile convergence (FMC) IMS platform to provide VoLTE and services for both mobile and landline users. This is the first commercial VoLTE and FMC network in Latin America.

 ZTE’s IMS solution supports not only narrow band access, but also broadband access technologies such as LTE and xPON. These capabilities allow Telefónica del Perú to lay the foundation of a future unified core network. In August 2015, after the commercial availability of the fixed IMS network, Telefónica del Perú began implementing FMC and IMS VoLTE projects in order to fully improve its competitiveness in the Mobile Internet era.

Telefónica del Perú continued to choose ZTE as the only vendor to implement IMS for this FMC project. ZTE upgraded the entities in the existing IMS network and built a new VoLTE session border controller (SBC) to complete the delivery.

ZTE’s IMS solution provides a set of converged voice services in combination with the services already provided by the existing legacy network. The solution provides VoLTE high definition voice and video service, as well as voice and data combined services over LTE. ZTE delivered the project in less than 10 months, in a multi-vendor environment and supporting full network redundancy.

Pedro Planas, CTO at Telefónica del Perú said: “Telefónica del Perú has been and will be active on the evolution of its network to provide more profitable and competitive services for our users while reducing our TCO. We rely on ZTE to perform the network modernisation project for both fixed and mobile networks.

The whole project has been implemented quickly and smoothly and has demonstrated the management and delivery skills of ZTE. The new challenge for Telefónica del Perú is the evolution of the network toward virtualization technologies. We are very pleased to continue our collaboration with ZTE, a Telefónica reference partner in NFV technologies.”
