Abstract: A data processing device comprises processing module capable of receiving from equipment in a communications network primary data defining events in at least one primary format, and delivering to a management device in the network secondary data defining alarms representing events, in a secondary format. The processing module comprise an interpreter provided with conversion rules, arranged in the form of scripts associated with the various primary event formats, and arranged to convert, using these rules, primary data received in one of the primary formats into secondary data in the secondary format which can be interpreted by the management device.

Abstract: A method for retrieving within a telecommunication network available network connection types at a given location provided by access points by means of a telecommunication network device (M), where the available network connection types at a given location are stored in an information system, the telecommunication network device (M) establishes at least one connection towards said information system, and queries for available network connection types using the given location. And a method for providing within a telecommunication network available network connection types at a given location provided by access points by means of a telecommunication network device, where an access points provides its coverage (C1, . . . , C5) and its connection type in an information system for retrieving available network connection types. The invention further relates to a server, an information system, a telecommunication device, and an access point.

Abstract: The present invention provides a method, a mobile node, an access network as well as a computer program product for enabling of a handover of a mobile node between access networks in the framework of mobile IP. The invention focuses on service continuity of an internet service that is launched by the mobile node. Enabling of a handover of the mobile node accounts for the QoS required by the internet service and the QoS provided by various access networks. Handover of a mobile node is only enabled if the new access network fulfills the QoS requirements of the internet service. Service discontinuity may therefore effectively be eliminated.

Abstract: A data processing device (1) comprises processing means (4) capable of receiving from equipment (3) in a communications network primary data defining events in at least one primary format, and delivering to a management device in the network (2) secondary data defining alarms representing events, in a secondary format. The processing means (4) comprise an interpreter (5) provided with conversion rules, arranged in the form of “scripts” associated with the various primary event formats, and arranged to convert, by means of these rules, primary data received in one of the primary formats into secondary data in the secondary format which can be interpreted by the management device (2).

Abstract: A device (D) is dedicated to the management of data persistency within an equipment management system (EMS) of a communication network that includes a large variety of network equipment (NE-i), where the equipment management system (EMS) is coupled to the equipment and to a network management system (NMS), and that includes a management information tree (MIT), coupled to the device (D), representing links between equipment (NE-i), and that includes primary data. This management device (D) includes configurable conversion resources (MTR) that are responsible for converting at least some of the primary data of the management information tree (MIT) into persistent data in accordance with persistency models which are each associated with different storage media (FP, BD), with a view to their storage in the storage medium which is associated with the persistency model that has been used for their conversion.

Abstract: A management device or arrangement (D) for a communication network which includes a multiplicity of network equipment elements, each associated with a primary data management protocol, includes, firstly, mediation means (MM) coupled to equipment elements and to functional interface means (MIF) and with system interface means (MIS) coupled to a network management system (NMS), and secondly protocol adaptation modules (Pa-j), in number at least equal to the number of management protocols associated with the equipment elements. The protocol adaptation modules (Pa-j) are each charged i) with converting the primary data coming from an equipment element (NE-ij) in accordance with a management protocol, into secondary data adapted to the mediation means (MM), and ii) to convert the secondary data, which are intended for an equipment element (NE-ij), into primary data in accordance with a management protocol adapted to this equipment.

Abstract: A system (D) is dedicated to managing the display of images representing network equipments (NE) of a communication network. The equipments (NE) include elements associated with hierarchical levels, and each element is associated with a set of primary data which represents it within the level to which it belongs with no specific attachment to a level higher than its own and/or at least one set of secondary data which represents it within the level to which it belongs when it is attached to a level higher than or equal to its own. The system (D) includes management means (GM) adapted, in the event of receiving a request designating a chosen level of an equipment with or without attachment, to access the memory in which the sets of primary and secondary data are stored in order to extract therefrom the sets of primary or secondary data of the elements of the equipment that belong to the designated level and to levels lower than it, according to whether said level is designated with or without attachment.

Abstract: To solve problems of congestion of processing caused by the simultaneous occurrence of a very large number of alarms, the alarms are processed off-line or at least as not particularly urgent tasks. In practice, assessing the severity of an alarm is not treated in itself as an urgent event, even if the assessed severity indicates that the alarm is associated with a very serious event. It is shown that by operating in this way it is possible to retain control over a system for managing a transmission network and to avoid being unable to react if the network is subject to a major disruption, in particular if a very high rate link fails.
