Citing momentum in VoLTE, Huawei confirmed that, as of the end of 2014, it had secured 35 new VoLTE contracts, of which three networks have already been put into commercial use.
The contracts include a leading tier-one operator in Europe, which has selected Huawei as its Virtual IP Multimedia Subsystem (vIMS) supplier for cloud-based VoLTE deployment.
In May 2014, PCCW-HKT and Huawei jointly announced the commercial launch of VoLTE in Hong Kong. At the time of deployment, it was the world’s first enhanced Single Radio Voice Call Continuity (eSRVCC)-enabled VoLTE base on the latest 3GPP release 10, which enables seamless call continuity for voice calls when switched over from LTE to 3G. Huawei conducted simplified integration that resulted in zero-impact on the existing network in terms of provisioning and billing center, legacy CS network.
