  • METHOD AND APPARATUS FOR SWITCHING MULTI-PARTY CALL, AND MULTI-CHANNEL TERMINAL
    Publication number: 20180176386
    Abstract: A method and an apparatus for switching a multi-party call, and a terminal are provided. The method includes detecting whether a multi-party call realized on a current network side needs to be switched to a multi-party call realized on a terminal, or a multi-party call realized on a current terminal needs to be switched to a multi-party call realized on a network side; and the multi-party call realized on a terminal and the multi-party call realized on a network side can be switched to each other based on the detection result. Therefore, diversified requirements of scenes and users can be satisfied.

  • Packet-switched network return
    Patent number: 9332461
    Abstract: Systems and methods for generating a Long Term Evolution network return procedure. A mobile terminal may generate, in absence of redirection instruction from a circuit-switched network, a Long Term Evolution network return procedure that, when instantiated by the mobile terminal, implements connection of the mobile terminal to a Long Term Evolution network based on measured signal strength of at least one Long Term Evolution network access point.

  • Packet-switched network return
    Patent number: 9307543
    Abstract: Systems and methods for generating a Long Term Evolution network return procedure. A mobile terminal may generate, in absence of redirection instruction from a circuit-switched network, a Long Term Evolution network return procedure that when instantiated by the mobile terminal implements connection of the mobile terminal to a Long Term Evolution network based on a ranking of measured Long Term Evolution network access points.
