Abstract: Various embodiments provide methods and apparatus for network-controlled DRVCC. In an embodiment method, a wireless user equipment may include requesting handover of a voice over Internet protocol (VoIP) call from a first network to a second network, activating a second radio, continuing the voice call on the circuit switched (CS) domain of the second network, and communicating data for applications other than the voice call via the first network. An embodiment method may include determining whether the first network supports voice-over-LTE (VoLTE) calls, and deactivating a radio in response to determining that the first network supports VoLTE calls. An embodiment method may include determining whether a quality of the VoIP call satisfies a quality threshold, deactivating the radio continued to the second network when the quality of the VoIP call satisfies the quality threshold, and activating the second radio when the VoIP call quality does not satisfy the quality threshold.
