    摘要： A method of offload selection for a UE to select between 3GPP RAT and WLAN cell is provided. The UE receives configuration information that applies to selecting WLAN or 3GPP radio access technology (RAT). The UE determines if the UE may perform WLAN offload by evaluating 3GPP radio access network (RAN) conditions where at least one RAN condition is related to a radio signal strength or a radio signal quality in 3GPP RAT. The UE then determines if there is at least one suitable WLAN cell by evaluating WLAN conditions. The UE also determines if there is candidate traffic for WLAN offload. Finally, the UE steers the determined traffic to WLAN if the UE may perform WLAN offload and if there is at least one suitable WLAN cell. Otherwise, the UE steers the determined traffic to 3GPP RAT.

    摘要： 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.

    摘要： A method to manage call continuity in a network environment including a circuit-switched network and an IP multimedia subsystem (IMS) network is provided. A UE monitors one or more ongoing sessions in an IMS network, and the ongoing sessions contain at least one conference call. The UE detects a network-switching event for the UE to switch from the IMS network to a circuit-switched CS network. The UE then determines the one or more ongoing sessions within the IMS network to be released or transferred to the CS network. Finally, the UE performs a session transfer procedure for transferring the determined sessions.

    摘要： A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. In one embodiment, the access information comprises mapping information between the TMGI and the communication group ID.

    摘要： AT commands are used for controlling Mobile Termination (MT) functions and GSM/UMTS network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). 3GPP introduces multiple backoff timers and barring to solve network congestion problem. However, a TE does not know the timer value and the barring status. In accordance with one novel aspect, a new AT command interface that can respond timer value and barring status to the TE is proposed. It reduces wasteful retries and saves power consumption of the TE. Through the new AT command interface, the TE can query backoff timer status. Via unsolicited result code (URC), the MT can detect backoff timer status change and report updated backoff timer status to the TE.

    摘要： 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 first network supporting only Packet-Switched (PS) services or a second network supporting Circuit-Switched (CS) services. The controller receives a rejection message of a Tracking Area Updating (TAU) procedure from the first network via the wireless transceiver when a Circuit Switch Fallback (CSFB)-related call originated from or terminated to the mobile communication device is pending, determines whether the rejection message includes a predetermined rejection cause, and in response to the rejection message including the predetermined rejection cause, selects the second network to make the CSFB-related call via the wireless transceiver without re-attaching to the first network.
