    摘要: Adaptive Gain Control (AGC) is performed directly in a coded domain. A Coded Domain Adaptive Gain Control (CD-AGC) system modifies at least one parameter of a first encoded signal, resulting in corresponding modified parameter(s). The CD-VQE system replaces the parameter(s) of the first encoded signal with the modified parameter(s), resulting in a second encoded signal. In a decoded state, the second encoded signal approximates a target signal that is a function of two signals, including the first encoded signal and a third encoded signal, in at least a partially decoded states. Thus, the first encoded signal does not have to go through intermediate decode/re-encode processes, which can degrade overall speech quality. Computational resources required for a complete re-encoding are not needed. Overall delay of the system is minimized. The CD-AGC system can be used in any network in which signals are communicated in a coded domain, such as a Third Generation (3G) wireless network.

    摘要: The invention relates to a method for controlling overload in a packet-switched network, especially in a network where the Transmission Control Protocol (TCP) is used as the transport layer protocol. In order to inform the traffic source at a very early stage that the network is getting overloaded or congested, the transmission of acknowledgments traveling towards the source is only allowed if enough tokens are available. A token-based mechanism calculates the number of tokens on the basis of resource conditions such as a spare forward buffer capacity in a network node. Thereby, a threshold for a buffer occupancy or a rate for delaying the acknowledgments do not have to be determined. The acknowledgments are constrained closely related to the current network resource and not to the characterization of the data traffic. As a result, the overload control is significantly robust.
