Abstract: A communications apparatus and associated method communicating with at least one cellular network includes a radio transceiver and a processor. The communications apparatus includes a radio transceiver, capable of transmitting or receiving wireless radio frequency signals to or from a cellular network; and a processor. The processor is configured to: receive an incoming call request message that will trigger a Circuit Switch Fall Back (CSFB) procedure or a Evolved Packet System Fall Back (EPS FB) procedure from the cellular network via the radio transceiver, query a user to accept or reject the incoming call request before triggering the CSFB procedure or the EPS FB procedure, and determine whether to trigger the CSFB procedure or the EPS FB procedure based on a response to the query from the user.

Abstract: A communications apparatus communicating with at least one cellular network includes a radio transceiver and a processor. The radio transceiver is capable of transmitting or receiving wireless radio frequency signals to or from an air interface in the cellular network. The processor is configured to determine whether an inter-RAT change will be triggered in a subsequent procedure when the communications apparatus is in a connected mode. When the processor determines that an inter-RAT change procedure will be triggered, the processor is configured to selectively perform a predetermined procedure instead of the subsequent procedure to avoid the inter-RAT change.
