Abstract: A communications apparatus includes a baseband signal processing device, an RF signal processing device, a memory device, and a processor. The processor transmits a normal call-establishment signal with a remote identifier to a network to originate a normal call in response to a first call-origination request with the remote identifier, receives an indication message indicating that the normal call is routed as an emergency call from the network, records the remote identifier in the memory device, and when receiving a second call-origination request with the remote identifier, transmits an emergency call-establishment signal with the remote identifier to the network to originate an emergency call in response to the second call-origination request.

Abstract: A mobile communication device including a first RF device, a second RF device, and a controller is provided. The first RF device performs wireless transmission and reception utilizing a first RAT. The second RF device performs wireless transmission and reception utilizing a second RAT. The controller uses a first subscriber identity to make a first call or conduct a first data session via the first RF device, determines whether a dual connectivity on the first RAT and the second RAT is supported in response to a request for using a second subscriber identity to start a second call or a second data session via the second RF device, and allows the second call or the second data session to start during the first call or the first data session in response to the dual connectivity on the first RAT and the second RAT being supported.

Abstract: Methods and apparatus are provided for a voice over LTE system to shorten the call set up time. In one novel aspect, the mobile origination (MO) UE starts the UE-initiated dedicated resource allocation before receiving any responses from the remote UE. In another embodiment, the mobile termination (MT) UE starts the UE-initiated dedicated resource allocation upon receiving the INVITE from the remote UE. In one embodiment, the UE adjusts the timeout value based on the PLMN information in its PLMN database. The timeout value can be set to be zero if early reservation is allowed. Upon timer expires, the UE starts UE-initiated dedicated resource allocation. In one novel aspect, the MO UE retrieves the codec information of a remote UE from its peer profile information database and uses a matching codec in its INVITE message. In another embodiment, the MT MO includes the SDP answer in its 180 RINGING message.

Abstract: A mobile communication device including a first RF device, a second RF device, and a controller is provided. The first and second RF devices perform wireless transmission and reception utilizing a first RAT and a second RAT, respectively. The controller detects, during a communication with a first cell using a first subscriber identity, an incoming event for making a voice call or conducting a data session using a second subscriber identity via the second RF device, and switches the communication associated with the first subscriber identity to a second cell which utilizes the first RAT in a frequency band on which dual connectivity over the first and second RATs is supported, or enables the voice call associated with the second subscriber identity to be made via the first RF device when the communication associated with the first subscriber identity is performed via the second RF device.

Abstract: A mobile communication device including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a 3rd Generation Partnership Project (3GPP) network using a first Radio Access Technology (RAT). The controller establishes one or more radio bearers with the first 3GPP network via the wireless transceivers, and establishes a secure tunnel with a non-3GPP interworking gateway of a second 3GPP network via the radio bearers. The second 3GPP network utilizes a second RAT. Also, the controller registers, via the secure tunnel, an IP Multimedia Subsystem (IMS) service with an IMS server communicatively connected to the second 3GPP network, so as to make a voice call over the first 3GPP network.
