摘要： Communication over lossy packet networks such as the Internet is hampered by limited bandwidth and packet loss. The present invention provides a path diversity transmission system for improving the quality of communication over a lossy packet network. The path diversity transmission system explicitly sends different subsets of packets over different paths, thereby enabling the end-to-end application to effectively see an average path behavior. Generally, seeing this average path behavior provides better performance than seeing the behavior of any individual random path. For example, the probability that all of the multiple paths are simultaneously congested is much less than the probability that a single path is congested. The resulting path diversity can provide a number of benefits, including enabling real-time multimedia communication and simplifying system design (e.g., error correction system design). Two exemplary architectures for achieving path diversity are described herein. The first architecture is based on source routing, and the second architecture is based on a relay infrastructure. The second architecture routes traffic through semi-intelligent nodes at strategic locations in the Internet, thereby providing a service of improved reliability while leveraging the infrastructure of the Internet.

摘要： A method for performing a soft-handoff in a mobile streaming media system, and a method for performing a hard-handoff in a mobile streaming media system are is disclosed. In the soft-handoff embodiment, the present invention detects that a channel quality between a mobile client and a first base station remains above a drop threshold and that a channel quality between the mobile client and a second base station increases from below to above an add threshold. The present embodiment then sends a first multiple description bitstream from the first base station to the mobile client and sends a complementary second multiple description bitstream from the second base station to the mobile client. This method thereby provides improved utilization of wireless bandwidth during soft-handoffs, in contrast to conventional systems where the same bitstream is transmitted from each base station. In both the cases of soft-handoffs and hard-handoffs, when a mobile client enters a cell whose base station has no free capacity, the base station may prevent call dropping by reducing the number of descriptions being served to the existing clients and thereby providing capacity (at least one description) for the new client. These methods provide improved utilization of wireless bandwidth during soft-handoffs, and reduced probability of service disruption during both soft-handoffs and hard-handoffs.
摘要翻译：公开了一种用于在移动流媒体系统中执行软切换的方法，以及用于在移动流媒体系统中执行硬切换的方法。在软切换实施例中，本发明检测到移动客户端与第一基站之间的信道质量保持高于丢弃阈值，并且移动客户端与第二基站之间的信道质量从下至上增加阈。本实施例然后将第一多个描述比特流从第一基站发送到移动客户端，并将互补的第二多个描述比特流从第二基站发送到移动客户端。因此，与从每个基站发送相同比特流的常规系统相比，该方法从而提供了在软切换期间无线带宽的改进的利用。在软切换和硬切换的情况下，当移动客户端进入其基站没有可用容量的小区时，基站可以通过减少向现有客户端提供的描述的数量来防止呼叫丢弃，从而提供新客户端的容量（至少一个描述）。这些方法在软切换期间提供了无线带宽的改进的利用，并且在软切换和硬切换期间降低了服务中断的概率。
