摘要： The present invention relates to a system comprising a managing system and a number of managed systems in which management operations can be sent from the managing system to the managed systems over a management interface. Redundancy is provided through replicating a management operation in a first of said managed systems and sending the operation to at least one further managed system. A method of replicating management operations is also provided according to which it is established which instance operations that correspond to a management operation and for each instance operation examining if any replication conditions are given, and if such are fulfilled, replicating the operation and invoking it in a redundant system.

摘要： A complex system, e.g. a telecommunications network, is monitored for fault conditions. In order to correlate the alarms to establish which alarms (e.g. 31, 32, 33) have a common cause, a logical connectivity model is used in which a logical property is transferred between related logical elements (e.g. 41, 52) in response to the element (41) being alarmed. If as a result of such transfer the value of the logical property exceeds a threshold value for any element (61) a correlation is established and the element (61) highlighted (72) as the probable cause of the alarms.

摘要： A telecommunications network architecture is known comprising a switching system for effecting basic call processing to set up, maintain and clear calls, and service-providing means (SPA) communicating with said switching system for providing services additional to said basic call processing. Due to the high availability requirements typically placed on telecommunications networks, the service providing means will generally need to be of a fault-tolerant design. A fault-tolerant architecture is provided that relies on the checkpointing to a reliable store (55) of state data for services currently being provided from first service logic (50) of the service-providing means; should the first service logic (50) fail, a second service logic (52) is brought into operation and provided with required state data on current services from the backup store (55). To reduce the amount of checkpointing of data by the first logic (50), state data is only checkpointeed when the correspponding call has reached a stable phase, the loss of a call during setup being much more acceptable than after it is been established.
摘要翻译：已知一种电信网络架构，其包括用于实现基本呼叫处理以建立，维护和清除呼叫的交换系统，以及与所述交换系统通信的服务提供装置（SPA），用于为所述基本呼叫处理提供附加服务。由于通常放置在电信网络上的高可用性要求，服务提供装置通常需要具有容错设计。提供了一种容错架构，其依赖于对服务提供装置的第一服务逻辑（50）提供的服务的状态数据的可靠存储（55）的检查点; 如果第一服务逻辑（50）失败，则第二服务逻辑（52）被投入运行，并且从备用存储器（55）提供关于当前服务的所需状态数据。为了减少第一逻辑（50）对数据的检查点数量，仅当相应的呼叫已经达到稳定阶段时才会检查状态数据，在建立过程中的呼叫丢失比建立之后更为可接受。

摘要： Simultaneous events reported to an equipment management system are compared with historical data in order to establish whether there is a relationship between the events. Historical data is used to determine the statistical probability of the events occurring independently simultaneously. If this probability is below a predetermined threshold this will suggest that the events are not independent, but are related. Such relationships are alerted to an operator, for example by highlighting or grouping on a screen display, assisting the operator in identification of related events, without the need for prior knowledge of the relationships in the system. The events may be alarms generated by faults in a network. The identification of related faults at different points in the network assists identification of their common cause. The historical database may be updated by further event occurrences as they are reported to the equipment management system, thereby enlarging the database to make the results more statistically accurate. Events may be reported to the system automatically or by human agency. To allow for systematic delays in event reporting, alarms from one source may be compared with alarms from another source occurring a fixed time later or earlier.
摘要翻译：将与设备管理系统报告的同时事件与历史数据进行比较，以确定事件之间是否存在关系。历史数据用于确定事件独立同时发生的统计概率。如果这个概率低于预定阈值，这将表明事件不是独立的，而是相关的。这样的关系例如通过在屏幕显示上突出显示或分组来提醒操作者，帮助操作者识别相关事件，而不需要系统中的关系的先前知识。事件可能是由网络中的故障产生的警报。识别网络中不同点的相关故障有助于确定其常见原因。历史数据库可以通过进一步的事件发生而更新，因为它们被报告给设备管理系统，从而扩大数据库以使结果更统计学准确。事件可能会自动或由人力机构报告给系统。为了允许事件报告中的系统延迟，可以将来自一个源的报警与来自固定时间之后或之前发生的另一个源的报警进行比较。

摘要： In a telecommunications network, such as the public switched telephone network, account must be taken of faults which can occur in the network. For instance, on occurrence of a local exchange failure, it is known to apply control such as route gapping and code blocking. The invention is concerned with detection of failure of a local exchange (116, 118) in a communications network. It relies on a combination of parameters, each parameter in the combination having to meet predetermined criteria. In particular, a local exchange failure is recognised when the average value of the All Circuits Engaged (ACE) parameters over all traffic routes into a local exchange rises in a significant manner and the average value of the Circuits in Service (CCTS IS) parameters over all traffic routes into that exchange decreases in a significant manner.

摘要： There is described a method of operating a fault management system for an access network which forms part of a public telecommunications network. In the access network, terminating lines in the form of pairs of copper wires extend from a local switch (10) through a series of nodes to terminal equipment provided for user of the network. The fault management system includes a test head (104) and an access network management system (102). Each night, the test head (104) performs a series of tests on each of the terminating lines. The results of the tests are transmitted to the access network management (102). The test results are then converted into circuit scores, each of which is indicative of the operational quality of the tested circuit. For each node, the circuit scores of the tested circuits passing through the node are combined to produce a node score which is indicative of the operational quality of the node. In order to identify the node having the worst operational quality and therefore most in need of investigation, the nodes are ranked in accordance with their node scores. When a customer reports a fault, the test head (104) performs a series of tests on the customer's line and transmits the results to the management system (102). The management system (102) checks the test results for the presence of a suspected fault and identifies the nodes through which the line passes. Then, for each of the identified nodes, it evaluates a score for each one of a set of factors and combines the scores to produce a combined score representative of the likelihood of the suspected fault being present at the node. In order to assist in identifying the node which is causing the suspected fault, the nodes are then ranked in accordance with their combined scores.

摘要： The invention relates to a method of preventing an overload in a telecommunications network node. The network comprises at least one service node (CN; SCP) and at least one other node (PN; SSP) from which the service node receives service requests. According to the method, the service node transmits restriction requests (CG) to a node connected thereto, so that said node would restrict the number of service requests it transmits towards the service node. The restriction request comprises information on how the node should perform the restriction. A restriction request is transmitted at least whenever said information changes. In order to provide a simple and reliable method, the service node transmits a restriction request to a predetermined proportion of the total number of the service request messages fulfilling the criteria given, whereupon each individual service request message has a predetermined probability of triggering the transmission of a restriction request, the probabilities being selected in such a way that the total number of the restriction requests is smaller than the total number of the service requests.
