Abstract: A mobile communication device including a wireless transceiver and a wireless transceiver is provided. The wireless transceiver performs wireless transmission and reception to and from a first service network and a second service network. The controller uses a first subscriber identity card to establish one or more first radio bearers with the first service network via the wireless transceiver, uses a second subscriber identity card to set up an Internet Protocol Security (IPsec) tunnel with an evolved Packet Data Gateway (ePDG) of the second service network via the first radio bearers, and uses the second subscriber identity card to register an IP Multimedia Subsystem (IMS) service with the second service network via the IPsec tunnel.

Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver is configured for transmitting or receiving wireless radio frequency signals to or from a peer device. The processor determines whether re-synchronization in a communication mode with the peer device is required according to a determination rule. When the re-synchronization is required, the processor transmits a message to the peer device via the radio transceiver to trigger a re-synchronization procedure. The processor determines whether the re-synchronization is required in a connected mode.

Abstract: A communications apparatus includes an RF signal processing device, a baseband signal processing device and a processor. The processor controls operations of the RF signal processing device and the baseband signal processing device, camps on a first cell of a first RAT, receives a predetermined set of system information (SI) from one or more second cells of a second RAT and stores the predetermined set of SI in an SI early-reading database. When performing a RAT change procedure to switch from the first RAT to the second RAT is required, the processor further retrieves the predetermined set of SI of a target cell of the second RAT from the SI early-reading database and performs the RAT change procedure to camp on the target cell based on the retrieved predetermined set of SI.
