摘要： An overload or congestion condition on an access medium (24) of a communication network (22) is indicated by at least one condition that indicates an amount of access attempts on the access medium (24) corresponds to congestion or overload of a capacity of the access medium (24). Example conditions in disclosed embodiments include an occupancy level of the access medium, an average number of access probes associated with successful access attempts, a relationship between received power and interference, an emergency condition and network configuration or maintenance procedures. In a disclosed example, when congestion or overload occurs, at least one technique is implemented to reduce the congestion or overload for stabilizing the access medium. Disclosed example techniques for this include throttling the number of access attempt by reducing the number of users making access attempts or the frequency of user access attempts. Another example technique includes adjusting at least one access medium parameter that will reduce the access attempt traffic.

摘要： Methods and systems are provided for improving frame selection in wireless communications networks. During decoding of a frame, a base station generates an error burst representation associated with error bursts and stores the representation within the frame, thus forming an enhanced frame. The base station then transfers the enhanced frame to a network controller. A frame selection unit (“FSU”) within the network controller thereafter applies frame selection to the enhanced frame. The error burst representation can be analyzed to determine the quality of the enhanced frame. A “combined” frame, generated by combining an “acceptable” portion of the enhanced frame and an acceptable portion of a copy of the enhanced frame, can then be generated to substantially eliminate errors. The present frame selection methods and systems enable superior quality frames to be passed on to higher layers in a network's communications protocol (hereafter collectively referred to as “network”).
摘要翻译：提供了用于改善无线通信网络中的帧选择的方法和系统。在帧的解码期间，基站产生与错误突发相关联的错误突发表现，并将该表示存储在帧内，从而形成增强的帧。然后，基站将增强帧传送到网络控制器。网络控制器内的帧选择单元（“FSU”）将帧选择应用于增强帧。可以分析错误突发表现以确定增强帧的质量。然后可以生成通过组合增强帧的“可接受”部分和增强帧的副本的可接受部分而产生的“组合”帧，以基本上消除错误。目前的帧选择方法和系统使得优质的帧能够传递到网络的通信协议（以下统称为“网络”）中的较高层。

摘要： The present invention provides an improved RACH access burst arrangement and frame structure. That is, the invention provides methods and apparatus for supporting more than one access burst length in the UMTS access channel structure. Preferably, two access burst lengths are supported, e.g., 5 ms and 10 ms. Such an arrangement is advantageous in applications where it is beneficial to have fast access latency such as, for example, voice or other forms of real-time traffic. Also, the invention provides methods and apparatus for supporting multiple frame sizes. It is to be appreciated that further enhancement to access latency can be obtained by having the UMTS physical layer support multiple frame sizes. The access burst signal transmitted by a remote terminal over the RACH may be an access request or data packets in the case where the RACH is being utilized for UMTS short message services.
摘要翻译：本发明提供了一种改进的RACH接入突发布置和帧结构。也就是说，本发明提供了用于在UMTS接入信道结构中支持多于一个接入突发长度的方法和装置。优选地，支持两个接入突发长度，例如5ms和10ms。这样的布置在有利于具有快速访问延迟（例如语音或其他形式的实时业务）的应用中是有利的。此外，本发明提供了用于支持多个帧大小的方法和装置。应当理解，可以通过使UMTS物理层支持多个帧大小来获得对访问延迟的进一步增强。在RACH用于UMTS短消息服务的情况下，远程终端通过RACH发送的接入脉冲串信号可以是接入请求或数据分组。
