Abstract: A method of redialing with user equipment (UE) under handover limitation is disclosed. The method includes establishing a Voice over Wi-Fi (VoWiFi) call between the UE and a network, ending the VoWiFi call by the UE if a signal quality of the VoWiFi call is lower than a first threshold and a quality of another Radio Access Technology (RAT) is higher than a second threshold for calling, and sending a Session Initiation Protocol (SIP) INVITE message with the another RAT, from the UE to the network, to initiate a redialing after ending the VoWiFi call.

Abstract: Aspects of the disclosure provide a method for call management. The method includes receiving a signal from one of a first transceiver and a second transceiver in an electronic device. The signal indicates an incoming call managed by a first service provider that the electronic device subscribes service from. The method further includes determining whether the other of the first transceiver and the second transceiver is operative in an active call managed by a second service provider that the electronic device subscribes service from, and rejecting the incoming call when the other transceiver is operative in the active call managed by the second service provider.
