摘要： 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.
摘要翻译：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。

摘要： The invention relates to methods and devices for setting up connection for wireless relay network, wherein, mobile station utilizes the primary transmission path from itself and relay stations in the initial ranging and network entry procedure to send a request signal to base station. After the base station receives the request signal, it allocates a transmission path for the mobile station, and sends the information to the relay station on the path along the primary transmission path, and sends a response message to the mobile station. When the mobile station and the related relay stations obtain the corresponding response message and transmission path information, the signal sent by the mobile station is sent to the base station via relay stations along the transmission path.

摘要： The present invention discloses a method and a base station for allocating bandwidth for subscriber stations and a backhaul station through taking into joint consideration uplink and down bandwidth requests from respective subscriber stations in a wireless single-hop self-backhaul network. Upon receipt of information on bandwidth requests from the subscriber stations, the base station takes uplink and downlink bandwidth requests into joint consideration, allocates bandwidth for the subscriber stations and the backhaul station, and then notifies the subscriber stations and the backhaul station. Since bandwidth allocation is no longer based on uplink and downlink resources separately, a relatively high system bandwidth utilization ratio can be achieved and uplink and downlink bandwidth fairness for asymmetric traffic be ensured even if the network is overloaded.
摘要翻译：本发明公开了一种方法和基站，用于通过在无线单跳自回程网络中考虑来自相应用户站的联合考虑上行链路和下行带宽请求来分配用户站和回程站的带宽。在接收到来自用户站的带宽请求的信息时，基站共同考虑上行链路和下行链路带宽请求，为用户站和回程站分配带宽，然后通知用户站和回程站。由于带宽分配不再基于上行链路和下行链路资源，因此即使网络过载，也可以实现相对较高的系统带宽利用率，并确保非对称流量的上行和下行带宽公平性。
