Huawei has announced that its third-party terminal vendors in its Shanghai LTE/EPC IOT labs successfully get through the first CS FallBack (Circuit Switched Fallback) voice calls, the test-site business experience smooth , connecting time is short and smooth continuation. Completion of the test will help to deploy LTE/EPC pure data service operators continue to use the existing CS network to provide users with voice services.

Defined as the 3GPP standard solution, CS FallBack is the LTE/EPC initial selection of voice networking solutions. Huawei voice solution is based on CS Fallback SingleEPC, SingleCORE other solutions, not just small changes to the existing network, but also the full and effective reuse of existing network CS network, helping operators to effectively protect existing investments. Huawei's global leading provider of mobile field, can provide a complete end to end network architecture, including the 4G LTE/EPC network, CS core network and UMTS wireless networks, while third-party vendors to provide the terminal with CS FallBack function .

Product Line of Huawei core network domain, president ULTRASOUND group, said: "The success of this test indicates that Huawei's solutions 4G voice has matured, not only further promote the LTE/EPC industry, Huawei is also shown end to end solution capability EPC continued leadership in the industry. "

since 2004, Huawei deeply involved in NGMN, LTE/SAE and other standards to 271 LTE/SAE patents among the world's top four 11%of total global share of patents LTE. In the 3GPP packet domain, Huawei's continuous contribution to the influence of increased year by year Huawei, Huawei 2009 and 2010 the number of proposals submitted and ranked by the number of both the first (two years to submit more than 1600 total by more than 1,000), been widely recognized by global operators.
