ZTE Completes LTE/EPC Interoperability Tests with MSF

ZTE completed LTE/EPC interoperability tests conducted through the MultiService Forum. The tests were held by China Mobile and Vodafone in China and Germany, respectively.

ZTE provided LTE eNodeB equipment, Evolved Packet Core (EPC) and IP Multimedia Subsystems (IMS) components for testing at both sites. All the core network vendors underwent two scenarios of tests: single and interconnected laboratory. The objective was to assess the performance of equipment from multiple vendors under different implementation conditions. The end goal is to enhance the maturity of EPC inter-working in a multi-vendor environment and to promote core network development in the LTE eco-system.

In the experiment carried out in the Vodafone Germany laboratory ZTE was the exclusive supplier of eNodeB wireless equipment, and it successfully passed single laboratory and interoperability tests with Starent, Bridgewater, NEC and other vendors.

ZTE also joined the tests held at China Mobile's Beijing laboratory that measured end-to-end interoperability of the main LTE interfaces. In addition, the Company also concluded all three roaming experiments between the two laboratories and realized the industry's first IMS LTE call under a multi-vendor interconnection setting.

ZTE noted that it has deployed seven commercial LTE networks so far and participated in nearly 50 LTE trial networks.
