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.

Abstract: In a method for providing a network service, a registration signal for waiting is received from a second client device through the network service server when a first client device is utilizing a network service provided by a network service server. Information about the second client device is registered on a waiting list through the network service server. A connection signal is received from a third client device through the network service server when the first client device is disconnected from the network service server. The connection signal from the third client device is utilized for the third client device to request the network service provided by the network service server. The network service is provided to the third client device through the network service server when the information about the third client device is on the waiting list. The present invention also discloses a network service server.
