摘要： An Internet Protocol (IP) multimedia subsystem (IMS) network node receives a first collaborative session control signaling from a first wireless transmit/receive unit (WTRU) for an existing IMS collaborative session between at least the first WTRU and a second WTRU. The first WTRU is the initial controller of the session. The IMS network node detects that the first collaborative session control signaling from the first WTRU is degraded, and responsively initiates transfer of control of the session to the second WTRU at least in part by: transmitting an IMS-network-node-initiated collaborative session control transfer request to the second WTRU, receiving an acceptance from the second WTRU, and receiving a second collaborative session control signaling for the session from the second WTRU. The session is maintained, at least in part, through the IMS network node both before and after the second WTRU becomes the new controller.

摘要： An apparatus and method are disclosed for migrating between terminals. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive a request to migrate a first terminal to a third terminal while active communications are taking place on a first voice channel connecting the first terminal to a second terminal, establish a second voice channel with the third terminal, connect the first and second voice channels, and terminate without action of an end user of the first terminal a connection between the first terminal and the first voice channel. Additional embodiments are disclosed.

摘要： An email client method and server that allow a conference organizer to schedule a conference (e.g., conference call) using a calendar feature found in today's email applications. When the email client is installed to work with the user's email application, an option becomes available to allow access to a conferencing scheduling feature. The server is adapted to receive an incoming conference request via a data message (e.g., email message) and coordinate acceptances to the request. At the time of the conference, the server retrieves a list of conference participants/attendees and their contact information. The server determines whether or not each participant/attendee is a server participant. If the participant/attendee is a server participant, the server will initiate the conference by calling the multiple contact numbers associated with the participant/attendee. Otherwise, the server will call one contact number associated with the participant/attendee.

摘要： A method and apparatus provide enhanced navigational alerts for a vehicular two-way radio operating in a dispatch communication system. The integration and prioritization of navigational alerts with dispatch voice communication ensures that navigational alerts do not compromise mission critical voice communications. Navigational alerts in the form of navigational voice instructions and navigational tones are selectively prioritized based on predetermined parameters associated with the dispatch call.

摘要： This disclosure describes embodiments of systems and methods that use protocols and techniques that can stream audio from a video device to a separate device while reducing or eliminate audio/video synchronization errors. In some embodiments, these systems and methods use Voice over IP (VoIP) technology to stream audio to mobile devices with low latency, resulting in little or no user-perceivable delay between the audio stream and corresponding video presentation. As a result, users can enjoy both the audio and video of any video display in an establishment. In addition, the systems and methods described herein may be implemented in the home or other locations to allow viewers who may be hard of hearing to listen to audio clearly via headphones.
摘要翻译：本公开描述了使用协议和技术的系统和方法的实施例，其可以将音频从视频设备流传输到单独的设备，同时减少或消除音频/视频同步错误。在一些实施例中，这些系统和方法使用IP语音（VoIP）技术将音频流传输到具有低等待时间的移动设备，导致音频流和对应的视频呈现之间很少或没有用户可感知的延迟。因此，用户可以在企业中欣赏任何视频显示的音频和视频。此外，本文描述的系统和方法可以在家庭或其他位置实现，以允许可能难以听到的观众通过耳机清楚地收听音频。

摘要： A method and apparatus for enabling providers of PSTN toll free services to stagger simultaneous transmission of call setup signaling messages into an IP based teleconference bridge, supported by a VoIP network, by suspending a subset of calls and placing them on hold while placing other calls to be connected to the conference bridge are disclosed. The PSTN network can stagger calls by limiting the number of call setup signaling messages to be sent to the VoIP network within a predefined period of time interval and spread all the calls over multiple of such predefined periods. Prerecorded announcements or music can be played while the calls that have been placed on hold are in queue.
