ZTE has launched its IMS-based 4-net convergence voice solution, which supports one-number service [voice/SMS] and seamless voice switchover in GSM, WCDMA, LTE or Wi-Fi networks.
Subscribers can use a single number to answer a call or receive an SMS in various Radio Access Network scenarios.
With this solution, operators can provide voice communication with a higher quality than internet voice services such as Google voice and Skype. Additionally, they are also using the advantages of multi-network convergence to provide richer voice services, such as One Number multi-access and real-time voice switchover (DRVCC, SRVCC).
ZTE’s IMS solution supports seamless access for all network types, provides a targeted mature solution for the enterprise and individual subscribers, supports operator deployment of various multimedia convergence services, and facilitates operators working towards LTE.
