摘要： User equipment in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.
摘要翻译：无线通信系统中的用户设备基于所监视的调度信息来监视调度信息并本地检测上行链路信道的链路数据速率的变化。以这种方式，可以直接检测链路数据速率的变化而没有显着的延迟。然后将这种速率变化的直接或早期检测与适当的系统反应组合。所检测到的链接数据速率变化的信息优选地用于调整在用户设备中运行的IP应用的应用数据速率。作为替代或补充，基于相对重要性对数据分组进行分类，并且基于数据分组的分类并根据检测到的链路数据速率的变化，通过上行链路信道来选择信息的传输。

摘要： In a method of improved media frame transmission in a communication network. Initially a plurality of “original” or regular media frames are provided for transmission. According to the invention, robust representations of the provided regular media frames are generated and stored locally. Subsequently, one or more of the regular media frames is/are transmitted. The invention detects an indication of a loss of a transmitted media frame, and the idea is to transmit, in response to a detected frame loss, a stored robust representation of the lost media frame and/or a stored robust representation of a subsequent, not yet transmitted, media frame to increase the media quality.

摘要： In order to efficiently handle the switch between user media and announcement media, a basic step is to first determine a configuration of the user media. Next, a configuration of the announcement media to be presented is determined based on the determined user media configuration. Subsequently, the announcement media is configured according to the announcement media configuration, and the configured announcement media is finally sent to the intended user. In this way, the overall appearance or sound of the announcement will be virtually the same as or at least similar to the overall appearance or sound of the user media, preferably without distortions. This allows the user to perceive the announcement as clearly as possible.

摘要： In a method of improved session negotiation between first and second clients in a cellular telecommunication system, the two clients negotiating S10 and agreeing upon a first codec type for a session. The first and second clients then initiating the session and exchanging S20 media data frames according to the first codec type. Subsequently, during the initiated session, at least one of the first and second clients providing S30 an indication for a second codec type in at least one subsequent media data frame. Finally, upon receiving and recognizing said indication, the other of said first and second clients switching S40 to the indicated second codec type in a next media data frame, thereby enabling the first and second clients to exchange subsequent media frames utilizing the second codec type.

摘要： A receiver includes a detector for detecting a change in source of incoming media during an on-going communication session, and means to provide a reset signal in order to reset decoder states of a decoder in response to such a detected change before decoding new incoming media. In this way, a state mismatch can be avoided without the need for several active decoder instances in the receiver, leading to substantial savings with respect to overall complexity, memory usage and power consumption. This also means that media distortions can be eliminated or at least reduced when the decoded media is finally rendered by a player.
摘要翻译：接收机包括用于检测正在进行的通信会话期间进入媒体的源的变化的检测器，以及提供复位信号的装置，以便在对新的传入媒体进行解码之前响应于这种检测到的变化来重置解码器的解码器状态。以这种方式，可以避免状态不匹配，而不需要接收器中的几个主动解码器实例，导致相对于整体复杂性，存储器使用和功耗的显着节省。这也意味着当解码的媒体最终由播放器呈现时，可以消除媒体失真或至少减少媒体失真。

摘要： A method and apparatus for determining a location address for shared packet switched data. The data is to be accessible by a user of a first device and a user of a second device. A symmetric function is applied to a known identifier associated with the first device and a known identifier associated with the second device. The result of the function can then be used as an address for data to be accessible by users of both the first device and the second device, the data being stored on a remote server at a location defined by the address. The method ensures that the same address is calculated regardless of which identifier is used first, and that both devices can calculate the address without requiring any further signalling or capability/discovery mechanism.
