Huawei Technologies announced that it has successfully completed a circuit switched (CS) fallback voice call with a third-party handset provider.

Conducted at Huawei’s Long Term Evolution (LTE) and Evolved Packet Core (EPC) Interoperability Testing Lab in Shanghai, the call demonstrates that operators using LTE/EPC to provide pure data services will still be able to leverage its existing CS network to provide voice services.

“The successful completion is another example of our efforts to provide LTE/EPC end-to-end solutions to global operators to optimize their networks. Huawei is committed to working with our peers and partners to foster a vibrant telecommunications industry,” said Xu Weizhong, President of packet core product line, Huawei.
