摘要： An adaptive overload system for controlling the amount of traffic processed by a network access controller is described for a network access controller arranged to control a plurality of network access points. Each network access point provides traffic with access to the communications network and the system comprises determining at the network access controller if an overload condition exists, and if so, generating at least one global constraint to restrict the rate at which a network access point admits said traffic to the communications network. The controller then multicasts at least one global traffic constraint to one or more of said plurality of network access points. Each network access point receiving the global constraint then processes the global traffic constraint to determine a plurality of local constraint conditions. The receiving network access point performs the following steps to determine said local constraint conditions: determining a local predetermined gap interval to be imposed on said traffic; and determining an initial gap interval which differs from the subsequent local predetermined gap intervals, the initial gap intervals differing between each of said plurality of network access points. The initial gap intervals are determined in either a random or pseudo-random manner to ensure synchronisation effects at the network access controller which would otherwise occur in high call rate scenarios are removed.

摘要： In a communications network, a count (82) is maintained of the number of calls made to a selected number. The number may be that of an answering centre (6) or of any other destination which has the capacity to handle a multiplity of calls simultaneously. The count is automatically updated when calls are admitted to the number and when they are terminated. If a new call would take the number of calls in progress above a stored value for the maximum capacity of the number, then the call is rejected. In one implementation, resources are allocated dynamically on an Overload Control Server (66) to a particular destination number only when congestion occurs. The stored value for the capacity may be amended automatically depending on the response of the network to admitted calls. The value for the capacity may initially be estimated as a function of the holding times for calls to the destination number.
摘要翻译：在通信网络中，维持对所选号码的呼叫数量的计数。该号码可以是应答中心或具有同时处理多个呼叫的能力的任何其他目的地的号码。当呼叫被接纳到号码以及何时被终止时，计数将自动更新。如果一个新的呼叫将取得正在进行的呼叫数量超过一个存储的值，以获得该号码的最大容量，则该呼叫被拒绝。在一个实现中，只有在拥塞发生时，资源才能在过载控制服务器上动态分配到特定的目的地号码。存储的容量值可以根据网络对接入呼叫的响应自动修改。可以最初估计容量的值作为对目的地号码的呼叫的保持时间的函数。

摘要： Heat storage apparatus comprising at least one thermal store (300) comprising a chamber (301) having a gas inlet (306), a gas outlet (307), and a gas-permeable thermal storage media (303) disposed therebetween, the apparatus being configured such that, during operation, the flow path of agas flowing through the chamber (301) from inlet (306) to outlet (307) for transfer of thermal energy to or from the storage media (303) can be selectively altered in response to the progress of the thermal transfer, thereby enabling the flow path to bypass inactive upstream or downstream regions of the storage media where thermal transfer is complete or minimal, so as to minimise the pressure drop across the storage media. A baffle system (305) in a main flow passageway (312) may be used to control the gas flow path.
