    • The method of secure communication between the endpoints is used for the secret communication between endpoints locating in different gatekeeper management area, and the method includes: in the process of the caller endpoint calling the callee endpoint, the home gatekeeper of the callee endpoint generates the share secret key between the caller endpoint and the callee endpoint; the secure communication process is performed between the caller endpoint and the callee endpoint according to the share secret key. According to the secure communication method between the endpoints, the invention makes that secret communication mechanism between the endpoints locating the different gatekeeper management area has better expansibility and higher efficiency.
    • 端点之间的安全通信方法用于定位在不同网守管理区域的端点之间的秘密通信,该方法包括:在主叫端点呼叫被叫端点的过程中,被叫方端点的归属网守产生共享 主叫端点和被叫终端之间的秘密密钥; 根据共享秘密密钥在呼叫者端点和被叫方端点之间执行安全通信处理。 根据端点之间的安全通信方式,本发明使定位不同网守管理区域的端点之间的秘密通信机制具有更好的可扩展性和更高的效率。

    • Embodiments of the present invention disclose a method for buffering streaming media, including: determining whether there is no free buffer chunk to buffering streaming media currently in a playing buffer; if so, stopping downloading streaming media from the network; otherwise, buffering the streaming media downloaded from the network in the playing buffer; determining whether the time for playing the streaming media after being buffered in the playing buffer is later than the time for playing the steaming media according to the playing speed; if so, stopping playing streaming media in the buffer chunk; otherwise, playing streaming media in the buffer chunk. In accordance with the present invention, the problem of covering streaming media not being played in playing buffer and playing streaming media disconnectedly caused by the difference between the speed of downloading and playing streaming media is avoided by respectively controlling the process of downloading and playing streaming media. In view of the above, it is possible to guarantee that no error occurs in the process of buffering and playing streaming media, and ensure the quality for playing streaming media. Embodiments of the present invention further disclose an apparatus for buffering streaming media.
    • 本发明的实施例公开了一种用于缓冲流媒体的方法,包括:确定是否没有空闲缓冲区块缓冲当前在播放缓冲器中的流媒体; 如果是,请停止从网络下载流媒体; 否则,缓冲在播放缓冲器中从网络下载的流媒体; 确定在播放缓冲器中缓冲后播放流媒体的时间是否比根据播放速度播放蒸汽媒体的时间晚; 如果是这样,停止在缓冲区块中播放流媒体; 否则,在缓冲区块中播放流媒体。 根据本发明,通过分别控制下载和播放流媒体的处理来避免覆盖播放缓冲器中播放的流媒体和播放流媒体间的不兼容的流媒体问题, 。 鉴于上述情况,可以保证在缓冲和播放流媒体的过程中不会发生错误,并确保播放流媒体的质量。 本发明的实施例还公开了一种用于缓冲流媒体的装置。
