  • Publication number: 20140376511
    Abstract: Methods for transporting a media call between an IMS server and a User Equipment (UE) and of handing over the media call between a cellular network and a WLAN are provided. In an embodiment, the media call data and signaling are split such that the data is transported over the WLAN and the signaling is transported over the cellular network. In another embodiment, handover latency is reduced by using a dual registration process that registers the UE with an IMS server using both a WLAN-based contact and a cellular network-based contact. The media call can then be carried over the WLAN and/or the cellular network and can be handed over seamlessly from one to the other within minimal signaling.

  • Publication number: 20140364118
    Abstract: A method and apparatus to co-ordinate detection of incoming calls in a multimode dual-SIM single RF chain wireless communications device. Incoming voice over LTE calls cannot be detected by monitoring LTE paging messages. The method and apparatus described detect voice over LTE incoming call SIP signaling in one SIM while also perform paging monitoring for a circuit-switched call in another SIM in the dual-mode dual-SIM communication device. Using a duty cycle that alternates priority between LTE and circuit-switched monitoring ensures that no incoming voice call or text message will be missed.

  • Publication number: 20140192643
    Abstract: A communication device and method for offloading communications from a first communication network to a second communication network. The offloading decision can be based on one or more parameters defined in a communication framework. The communication framework can be, for example, Access Network Discovery and Selection Function (ANDSF) framework. The offloading of communication can be from a Long-term Evolution (LTE) network to a Wi-Fi network, or vice-versa. The communication framework can include, for example, positional, movement, signal quality, connection duration, a data rate, and/or quality of service (QoS) parameters.
