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.
