    • A method includes at a first customer premises equipment (CPE) device coupled to a multimedia distribution network, generating a first request for multimedia content. The method also includes sending the first request to a network node of the multimedia distribution network. The method further includes receiving the multimedia content from a virtual peer located at the network node and storing the multimedia content at the first CPE device. The method also includes receiving a message via the multimedia distribution network, the message indicating a transmission of a second request for the multimedia content by a second customer premises equipment (CPE) device. The method further includes transmitting at least a portion of the stored multimedia content to the second CPE device.
    • 一种方法包括在耦合到多媒体分配网络的第一客户端设备(CPE)设备上,生成对多媒体内容的第一请求。 该方法还包括将第一请求发送到多媒体分配网络的网络节点。 所述方法还包括从位于所述网络节点处的虚拟对等体接收所述多媒体内容并将所述多媒体内容存储在所述第一CPE设备处。 该方法还包括通过多媒体分配网络接收消息,该消息指示由第二客户驻地设备(CPE)设备传输多媒体内容的第二请求。 该方法还包括将所存储的多媒体内容的至少一部分发送到第二CPE设备。

    • A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to receive presence information from each presence source of a plurality of presence sources, wherein the presence information is associated with a user, receive a Session Initiation Protocol (SIP) Uniform Resource Identifier (URI) which identifies the user, wherein identification information associated with the user from each presence source is mapped to the SIP URI, select at least a portion of the received presence information to be utilized in determining a presence status of the user, determine the presence status of the user based on the selected presence information, and transmit the presence status and the SIP URI to a computing device operably coupled to an Internet Protocol Multimedia Subsystem (IMS) network. Other embodiments are disclosed.
    • 结合本公开的教导的系统可以包括例如具有控制器的服务器,该控制器从多个存在源的每个存在源接收存在信息,其中存在信息与用户相关联,接收会话发起协议 (SIP)标识用户的统一资源标识符(URI),其中与来自每个存在源的用户相关联的标识信息被映射到SIP URI,选择要用于确定存在状态的所接收的存在信息的至少一部分 基于所选择的存在信息来确定用户的存在状态,并将存在状态和SIP URI发送到可操作地耦合到因特网协议多媒体子系统(IMS)网络的计算设备。 公开了其他实施例。
