摘要： The present invention relates to a method for scheduling a data transmission to a user equipment in a communication system comprising at least one radio network controller (RNC) governing a number of base stations, wherein the communication system supports data transmission from a base station to an user equipment on a high speed packet access (HSPA) bearer or a dedicated channel (DHC) or on similar bearers in a CDMA2000 system. The method comprises the steps of: identifying at least one predetermined scheduling condition for data transmissions for the user equipment; determining at least one current scheduling conditions of the user equipment; comparing the predetermined scheduling conditions of the user equipment with the current conditions of the user equipment; selecting a bearer for the data transmissions during a session from a base station based on the comparison; and using the selected data bearer during the data transmission session or until a new data bearer has been selected. Furthermore, the invention relates to a user equipment, a radio network controller, a computer readable medium and mobile communication system for data transmissions such as VoIP service transmissions in wireless communications systems

摘要： A method for localized congestion exposure within a local loop in a cellular network that is performed by a localized congestion exposure receiver node of the local loop. The method includes receiving downlink packets destined for a downstream user device. The downlink packets have headers that indicate a level of congestion experienced by the downlink packets. The headers also indicate a level of expected downstream congestion declared by an upstream node. The method also includes forwarding the downlink packets to the downstream user device through a wireless connection. The method further includes sending packets upstream that have feedback indicative of the level of congestion experienced by the downlink packets and any congestion experienced within the localized congestion exposure receiver node.

摘要： The present invention is to select an adaptation scheme for the transmission of the encoded media that results in a satisfactory performance of the transmitted encoded media. A difference from the prior art is that each adaptation scheme defines a set of different transmission formats, wherein each transmission formats is a combination of at least two of the parameters the source codec bit rate, the packet rate, the number of frames of each packet (referred to as frame aggregation), and the level of redundancy. By using the different transmission formats, the transmission can be adapted to different operating scenarios and the performance is hence improved.
摘要翻译：本发明是选择用于传输编码媒体的适应方案，其导致所传送的编码媒体的令人满意的性能。与现有技术的不同之处在于每个适配方案定义了一组不同的传输格式，其中每个传输格式是源编解码器比特率，分组速率，每个分组的帧数的至少两个参数的组合（简称帧聚合）和冗余级别。通过使用不同的传输格式，传输可以适应不同的操作场景，从而改善性能。

摘要： A method is proposed for determining the round-trip delay for sending multimedia data, such as voice or video data, between a first network node and a second network node over a communications network, where data is encapsulated in data units comprising at least one frame of encoded data. The method includes the steps of: said first network node sending a request for reconfiguration of the data unit structure to the second node; the first node detecting a reconfiguration response from the second node, where the reconfiguration response comprises at least one data unit of data having a structure that corresponds to the request for reconfiguration. The first node then measures the time elapsed between sending the reconfiguration request and detecting the reconfiguration response and determines a value for roundtrip delay using said measured time. In accordance with a first embodiment, the request for reconfiguration is a request to change the encoding mode of the multimedia data. A node adapted to measure this round-trip delay is also proposed.
摘要翻译：提出了一种用于确定在通信网络上在第一网络节点和第二网络节点之间发送诸如语音或视频数据之类的多媒体数据的往返延迟的方法，其中数据被封装在包括至少一个帧的编码数据。该方法包括以下步骤：所述第一网络节点向第二节点发送数据单元结构重配置请求; 所述第一节点检测来自所述第二节点的重新配置响应，其中所述重新配置响应包括至少一个具有对应于重新配置请求的结构的数据数据单元。然后，第一节点测量发送重新配置请求和检测重新配置响应之间经过的时间，并使用所测量的时间确定往返延迟的值。根据第一实施例，重新配置的请求是改变多媒体数据的编码模式的请求。还提出了适于测量该往返延迟的节点。

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.
