    • Disclosed are a method for identifying a connection, mobile station and base station. The method comprises the steps of: assigning a MS ID to the mobile station when the mobile station enters into the coverage area of the base station; and assigning a connection ID to a connection when the connection is established between the base station and the mobile station. With the proposed solution, the data overhead could be reduced due to short Connection ID instead of 16-bit CID in 802.16e, especially for VoIP traffic. In addition, due to adjustable bit-length of Connection ID, the tuple could flexibly support different numbers of connections while keeping overhead in minimal.

    • A self-adaptive jitter buffer adjustment method for packet-switched network is presented in this invention, which involves both positive adjustment to jitter buffer and negative adjustment to jitter buffer. The positive adjustment part performs a positive adjustment to the jitter buffer according to an indication of a sequence number of the packet delaying, to absorb larger network jitters by dynamically detecting sequence numbers of the packets in the jitter buffer. The negative adjustment part performs a negative adjustment to the jitter buffer when the filling level descends, to match smaller network jitters by periodically detecting a filling level of the jitter buffer. This invention realizes the dynamic tracking of network jitter, so that a self-adaptive adjustment to the jitter buffer working parameters can be achieved. Comparing with traditional methods for self-adaptive buffer adjustment, the present method reduces the complicacy and computational costs of the self-adaptive jitter buffer adjustment algorithm. At the same time, the impact of self-adaptive jitter buffer adjustment on the performance of the entire system is greatly reduced.
    • 本发明提出了一种用于分组交换网络的自适应抖动缓冲器调整方法,其包括抖动缓冲器的正调整和抖动缓冲器的负调整。 正调整部根据分组延迟的序列号的指示对抖动缓冲器进行正调整,以通过动态地检测抖动缓冲器中的分组的序列号来吸收较大的网络抖动。 负调整部分在填充水平下降时对抖动缓冲器进行负调整,以通过周期性地检测抖动缓冲器的填充水平来匹配较小的网络抖动。 本发明实现了网络抖动的动态跟踪,从而可以实现对抖动缓冲区工作参数的自适应调整。 与自适应缓冲区调整的传统方法相比,本方法降低了自适应抖动缓冲区调整算法的复杂性和计算成本。 同时,自适应抖动缓冲区调整对整个系统性能的影响也大大降低。
