Abstract

A user equipment (UE) is configured to implement selective call initiation delay responsive to detection of a contemporaneous handover process. When a user provides input indicating initiation of a packet-switched call, the UE determines whether there is a handover process ongoing. If not, a call initiation message (e.g., a SIP INVITE message) is transmitted without further delay. However, if a handover process is ongoing at the time of the user input, the UE refrains from promptly transmitting the call initiation message and starts a timer of a predetermined duration to provide additional time for the handover process to complete. Responsive to the timer expiring or to the handover process completing before the timer expires, the UE then promptly transmits the call initiation message to initiate establishment of the packet-switched call over whatever network to which the UE is currently attached.
