  • Patent number: 11140593
    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.
