    • A method and apparatus for performing session release are provided. For a transferred communication session between a plurality of wireless transmit/receive units (WTRUs) and a remote device, wherein at least one of the WTRUs performs the transferred communication session in association with a first Internet Protocol Multimedia Subsystem (IMS) and at least one other of the WTRUs performs the transferred communication session in association with a second IMS, session release may include releasing the transferred communication session, a portion thereof, one or more of the WTRUs, or a collaborative session associated with the transferred communication session while maintaining service continuity. Any one of the plurality of WTRUs or the remote device may initiate the session release by transmitting a release request. Any one of the plurality of WTRUs may control the transferred communication session and may modify or reject a release request.
    • 提供了一种用于执行会话释放的方法和装置。 对于多个无线发射/接收单元(WTRU)和远程设备之间的传输通信会话,其中至少一个WTRU与第一互联网协议多媒体子系统(IMS)相关联地执行所传送的通信会话,并且至少一个 WTRU中的其他WTRU与第二IMS相关联地执行传送的通信会话,会话释放可以包括释放所传送的通信会话,其一部分,一个或多个WTRU,或与传送的通信会话相关联的协作会话,同时维护服务 连续性。 多个WTRU或远程设备中的任何一个可以通过发送释放请求来发起会话释放。 多个WTRU中的任何一个可以控制所传送的通信会话,并且可以修改或拒绝释放请求。

    • Systems, methods, and instrumentalities are disclosed to provide privacy for inter-user equipment transfer (IUT) subscribers and remote parties involved in sessions with IUT subscribers. A first UE may establish a session with a remote party. The first UE may seek to perform an IUT to a second UE. The first UE may send a first request for the IUT to a service centralization and continuity application server (SCC AS). The SCC AS may receive the first request and perform an authorization. The SCC AS may determine that the requested IUT is allowed for the session. The SCC AS may send a second request to the remote party indicating the requested IUT. The remote party may evaluate the second request and may accept or reject the second request.
    • 公开了系统,方法和工具,以便为涉及IUT用户的会话的用户间设备传输(IUT)用户和远程方提供隐私。 第一UE可以与远程方建立会话。 第一UE可以寻求对第二UE执行IUT。 第一UE可以向服务集中和连续性应用服务器(SCC AS)发送对IUT的第一请求。 SCC AS可以接收第一个请求并执行授权。 SCC AS可以确定所请求的IUT被允许用于会话。 SCC AS可以向对方发送指示所请求的IUT的第二请求。 远程方可以评估第二个请求,并且可以接受或拒绝第二个请求。

    • Systems, methods, and instrumentalities are disclosed to provide pre -negotiation of a video codec. An IP multimedia subsystem (IMS) entity, such as a service centralization and continuity application server (SCC AS), may send a first session initiation protocol (SIP) message to a circuit switched domain entity via an IMS core network. The first SIP message may correspond to a video call in an on-going IP multimedia subsystem (IMS) session. The first SIP message may include one or more video codecs supported by the SCC AS and the UE associated with the video call. The SCC AS may receive a second SIP message from the circuit switched domain entity. The second SIP message may include the video codec, which may be one of the video codecs included in the first SIP message. The SCC AS may send the video codec to a user equipment (UE) associated with the video call.
    • 公开了系统,方法和手段以提供视频编解码器的预先协商。 诸如服务集中和连续性应用服务器(SCC AS)之类的IP多媒体子系统(IMS)实体可以经由IMS核心网络向电路交换域实体发送第一会话发起协议(SIP)消息。 第一SIP消息可以对应于正在进行的IP多媒体子系统(IMS)会话中的视频呼叫。 第一SIP消息可以包括由SCC AS和与视频呼叫相关联的UE支持的一个或多个视频编解码器。 SCC AS可以从电路交换域实体接收第二SIP消息。 第二SIP消息可以包括可以是包括在第一SIP消息中的视频编解码器之一的视频编解码器。 SCC AS可以将视频编解码器发送到与视频呼叫相关联的用户设备(UE)。
