Abstract: Architecture for seamless role switching in application sharing. A multipoint control unit (MCU) can be used for connecting multiple clients over a network. An application sharing component establishes an application sharing session over the MCU, and application content is exchanged from a sharer client to one or more viewer clients. Each client can communicate a media connection preference to the session. Client sharer and viewer roles are defined during creation of the application sharing session. A client can seamlessly switch roles during the session from a viewer to a sharer, and vice-versa, so that different application content can be shared to the session viewers. The session can be restricted to only one sharer so that the viewing clients view one sharer client at a time.

Abstract translation: 应用程序共享中无缝角色切换的架构。 多点控制单元（MCU）可用于通过网络连接多个客户端。 应用程序共享组件通过MCU建立应用程序共享会话，应用程序内容从共享者客户端交换到一个或多个查看器客户端。 每个客户端都可以向会话传递媒体连接首选项。 在创建应用程序共享会话期间定义客户端共享器和查看器角色。 客户端可以在会话期间将角色从查看器无缝切换到共享者，反之亦然，因此不同的应用程序内容可以共享给会话查看者。 会话只能被限制为一个共享者，以便查看客户端一次查看一个共享客户端。

Abstract: Architecture for session management enabling the reusing of session attributes of a current session in creating a new session, for adding new participants to a call session. A telephony component manages IP-based call sessions. The telephony component can be an IP telephone or a personal computing device running an IP telephony application, for example. A header component includes attributes of an existing IP call session with multiple parties. The header component can be sent in an INVITE message when establishing the new IP call session, for example. An attribute selection component selects attributes of the existing IP call session to be reused with the new IP call session with the multiple parties and a different party or parties. A session replacement component replaces the existing IP call session with the new IP call session, including the attributes reused from the previous session.

Abstract translation: 用于会话管理的架构，能够在创建新会话时重新使用当前会话的会话属性，以便将新参与者添加到呼叫会话。 电话组件管理基于IP的呼叫会话。 例如，电话组件可以是IP电话或运行IP电话应用的个人计算设备。 头部组件包括与多方的现有IP呼叫会话的属性。 例如，当建立新的IP呼叫会话时，报头组件可以在INVITE消息中发送。 属性选择组件选择要与多方和不同方或双方进行新的IP呼叫会话重新使用的现有IP呼叫会话的属性。 会话替换组件将使用新的IP呼叫会话替换现有IP呼叫会话，包括从上一个会话重用的属性。
