Telefónica del Perú and ZTE have begun commercial operation of the first IP multimedia subsystem voice over long-term evolution (IMS VoLTE) network in Perú.
The deployment also marks the technology’s debut across Telefónica’s LATAM footprint, enhancing the operator’s market competitiveness in the region.
In 2012, Telefónica del Perú modernised its landline network with the deployment of an IMS core network to replace the legacy time-division multiplexing (TDM) switches. ZTE IMS solution supports most of the existing public switched telephone network/integrated services digital network (PSTN/ISDN) services and multiple legacy end user interfaces, such as basic rate interface (BRI), primary rate interface (PRI), plain old telephone service (POTS) or network-based call signalling (NCS),which helps Telefónica del Perú to successfully overcome the challenges of dealing with legacy TDM switches and to lower operating expenditures while maintaining legacy terminals and service integrity.
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.
Pedro Planas, CTO at Telefónica del Perú said: “Telefónica del Perú has been and will be quite 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.”
