    • A method for mitigating buffering delay in a TCP- encapsulated data stream transmitted over a network, the method comprising conducting the following steps at a node (200) in said network: receiving a first packet through a first interface (241), said first packet comprising data of said TCP- encapsulated data stream; receiving a second packet through a second interface (211), said second packet comprising an acknowledgment of segments of said TCP - encapsulated data stream; analyzing said first packet and said second packet to estimate an amount of outstanding data; using said amount of outstanding data to determine a state of buffer occupancy; updating a TCP Window field in said second packet in function of said state of buffer occupancy, and transmitting said updated second packet through said first interface.
    • 一种用于减轻通过网络传输的TCP封装数据流中的缓冲延迟的方法,所述方法包括在所述网络中的节点(200)处执行以下步骤:通过第一接口(241)接收第一分组,所述第一分组 包括所述TCP封装的数据流的数据; 通过第二接口(211)接收第二分组,所述第二分组包括所述TCP封装数据流的段的确认; 分析所述第一分组和所述第二分组以估计未完成数据的量; 使用所述数量的未完成数据来确定缓冲器占用的状态; 在所述缓冲器占用状态的功能下更新所述第二分组中的TCP窗口字段,并通过所述第一接口发送所述更新的第二分组。

    • Example embodiments provide methods for handling the transition of a mobile device from a first network to a second network, the second network operating according to a different communications protocol from the first network. One example embodiment includes terminating forwarding of the data packets from the first network to the mobile device; rebuilding headers of unforwarded data packets at the first network; and sending the rebuilt data packets from the first network to the second network. Another example embodiment includes resetting a header compression state at the second network; receiving unforwarded data packets from the first network at the second network, the unforwarded data packets being data packets the first network had not yet forwarded to the mobile device; and sending the unforwarded data packets from the second network to the mobile device.
    • 示例性实施例提供了用于处理移动设备从第一网络到第二网络的转换的方法,第二网络根据与第一网络不同的通信协议来操作。 一个示例性实施例包括将数据分组从第一网络转发到移动设备; 在第一个网络上重建未转发数据包的头; 以及将重建的数据分组从第一网络发送到第二网络。 另一示例性实施例包括在第二网络处重置头部压缩状态; 从所述第二网络处的所述第一网络接收未转发的数据分组,所述未转发的数据分组是所述第一网络尚未转发到所述移动设备的数据分组; 以及将所述未转发的数据分组从所述第二网络发送到所述移动设备。
