    摘要： A method to transfer control is presented. The method includes receiving a request to transfer control of a collaborative session from a first user equipment (UE). The method includes sending a request for the transfer of control of the collaborative session in response to the received request to a second UE, and receiving, in response to the sent request to the second UE, an indication of acceptance of the transfer of control of the collaborative session. The method includes sending a notification of status to the first UE of the control of the collaborative session in response to receiving, from the second UE, the indication of acceptance.

    摘要： An embodiment provides a user equipment that includes a processor configured to receive a Session Initiation Protocol (SIP) NOTIFY message transmitted by a network component as a result of a registration event. The SIP NOTIFY message contains at least a portion of information included in a first SIP message sent between a first user equipment and the network component. Another embodiment provides method and apparatus for a network node to determine whether filter criteria include one or more indicators that specify the need for information, and including in a second SIP message the information specified by the one or more indicators.

    摘要： In some examples, a user equipment (UE) detects a change in a radio access technology, and in response to the change in the radio access technology, receives information sent by a wireless network. The UE compares the received information to a policy to determine whether a feature is supported by the wireless network, and based on the comparing, sends an indication informing the wireless network which network type of plural different network types to use for sending a Session Initiation Protocol (SIP) message.

    摘要： A system and method in a user equipment (UE) for transferring an emergency session from a first network to a second network. The method includes transmitting a first registration request message to the second network; receiving a registration reject message from the second network; detecting the emergency session between the UE and the first network is ongoing; transmitting a second registration request message comprising an emergency registration request to the second network; and receiving a registration accept message for the emergency session.
