摘要： A receiver (100) includes a detector (140) 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 (120) 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 (100), 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 (130).
摘要翻译：接收器（100）包括用于在正在进行的通信会话期间检测输入媒体的源中的改变的检测器（140），以及用于提供重置信号以重置解码器状态的装置解码器（120）响应于在解码新的传入媒体之前检测到的这种变化。以这种方式，可以避免状态失配，而不需要接收器（100）中的几个活动解码器实例，从而导致整体复杂度，存储器使用和功耗相当大的节省。这也意味着当解码媒体最终由玩家呈现时可以消除或至少减少媒体失真（130）。

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 (Sl) is to first determine a configuration of the user media. Next, a configuration of the announcement media to be presented is determined (S2) based on the determined user media configuration. Subsequently, the announcement media is configured (S3) according to the announcement media configuration, and the configured announcement media is finally sent (S4) 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： User equipment (200) 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： A method and arrangement for controlling a balance between Packet Switched(PS) data, and Circuit Switched (CS) data in a cellular communication network. A network node is arranged in a cellular communication network to control communication of PS data between a first UE and a base station, and to control communication of CS data between a second UE and the base station. Both the first UE, the second UE and the base station are associated to the cellular communication network and are located in the cell. The network node comprises a controller 402 which is adapted to identify a risk of congested communication of data, and a transceiver 406 which is adapted to communicate PS data with the first base station, and to communicate CS data with the second base station. The controller is further adapted to request the second UE to change communication settings, and the controller is further adapted to reallocate transmission resources from the second UE, to the first UE.
