Abstract: The present invention relates to a method to be carried out by a network support apparatus for managing resources of the apparatus, a method for managing resources of a network node, an apparatus for supporting the operation of a network and a resource management device, which particularly enable the determination of load at the apparatus or network node to allow more resource efficient scheduling of PM functions. The method carried out by the network support apparatus for managing resources comprises determining a load at the network support apparatus based on the number of events generated by recordings activated by at least one performance management function in a time period; comparing the determined load with a threshold load smaller than or equal to the maximum load supported by the network support apparatus; and performing a resource management procedure according to the result of the comparing step.

Abstract: This disclosure provides a method, a Back-end-server (102, 400, 506) and a system (500) for protection of location information of a UE. The Back-end-server can receive (104, 202, 302) a request message from an operator interface (504) requesting location information of the UE. Based on probability criteria or blocking factors, it is determined (110, 208, 306-310) whether location information may be transferred to the operator interface. One advantage is that a quantitative security for the privacy of subscribers is provided, with which the privacy of the subscribers is not disclosed.

Abstract: A device (10) for processing events (4), including an identifier (8) identifying the event's type, and at least one parameter carrying information about a process, includes an event selector (20) and an event type recognizer (30). The device (10) is configured for receiving an event (4), providing the event (4) to the event selector (20), and providing the identifier (8) to the event type recognizer (30). The event selector (20) stores the provided event (4). The event type recognizer (30) determines, using at least one neural network unit, whether the identifier (8) corresponds to a type for which a subscription exists, and, if so, it causes the event selector (20) to transmit the event (4S) for processing by one or more applications. Furthermore, the device (10) is configured for allowing one or more types of event to be subscribed to. The invention also relates to methods for processing events (4).

Abstract: A system for managing congestion within a network domain includes an ingress node, an interior node, and an egress node. The ingress node receives and routes data units entering the network domain. The interior node detects whether a load exceeds one or more load thresholds and generates congestion marked data units. The egress node detects the presence of congestion marked data units and reacts to the detection of the presence of congestion marked data units by invoking a congestion control process.

Abstract: A network node for reserving resources for data flows in a communication network. The node detects a request for resource reservation for a new data flow and computes an admission test count based on descriptors of the new data flow and reservation counts, which represent reservation functions of descriptors of previously admitted data flows and which specify resources of the admitted data flows. The new data flow is admitted if the admission test count is smaller than a maximum allowable count. The reservation counts are then updated based on the descriptors of the new data flow. A plurality of admission formulas may thus be used to maintain aggregated reservation counts for data flows, the number of counts being independent from the number of flows.

Abstract: A module for routing packets of first and second optical signals comprising first and second inputs (A,B) for receiving the first and second optical signals and first and second outputs (C,D) for the optical signals. The module comprises optical switching means (8) for switching the first optical signal and the second optical signal to either one of the two outputs (C,D), and a correlator module (7). The correlator module comprises at least two optical correlators (9,10,11,12). The correlator module (7) is arranged to generate control signals for controlling the switching means (8) based on destination data in packets of the first and second signals such that if packets of the first and second optical signals overlap, the switching means directs the packet that was received first to the output (C,D) indicated by the destination data of that packet and the overlapping subsequent packet is directed to the other output (C,D) or blocked.

Abstract: In LTE, there is no control node that collects Performance Management (PM) data from base stations, like a Base Station Controller (BSC) or Radio Network Controller (RNC) does for 2G/3G systems. Instead, an Operating Support System (OSS) has to collect PM data directly from eNodeBs, thereby causing scalability issues. A method of improved PM for LTE networks uses the statistical counters defined in the eNodeB and counters created from elementary events and parameters of events. Specific counters or user-defined counters can be defined that are, for example, not traditionally implemented in the nodes, or that use events from additional Network Elements (NEs). The counter files and events are collected by an observation gateway or directly by the PM application, and are monitored in different time scales. The counters are also aggregated for different time periods, thereby providing scalability and time-based statistics for the counter values.

Abstract: A method of managing quality of service in an IP network is provided. The method comprises identifying, at an egress edge node of the network, that congestion is present in one or more routers within the network. Data flows for termination to remove the congestion are selected. At least one flow termination notification is sent from the egress edge node to an ingress edge node of the network, the at least one flow termination notification identifying the selected data flows. Low priority flows from the selected data flows are terminated at the ingress edge node immediately. High priority flows are terminated only if congestion is still present after a predetermined delay period. The delay may be applied in the ingress edge node or the egress edge node. The invention also provides a method for admitting low priority flows into the network only if the network has resources available for a number of high priority flows above a dynamically determined threshold.

Abstract: A method of and an Operating Support System, OSS, system (20) for Performance Management, PM, of a mobile telecommunications system (1) comprising a plurality of nodes (6) and radio access units (5) servicing a plurality of cells (15) generating a plurality of operational events data (13) and counter values (14) measured periodically for a first Result Output Period, ROP. Events data (13) and counter values (14) originating from the nodes (6) and radio access units (5) are collected (21; 40), aggregated (23; 41) periodically for a second and further ROPs having a duration longer than the first ROP. From the collected events data (13) further counter values are created (22, 42) periodically for the second and further ROPs. The aggregated and further counter values are processed (24; 43) corresponding to the originating nodes (6), radio access units (5) and ROP, and the processed counter values are analyzed (24; 44) for providing system operational performance indicia in different time scales.

Abstract: A system and a method are described herein which provide for congestion handling in a packet switched network domain. In case of congestion overload is measured by a core node, the data packets in proportion to the overload are marked and the signaled overload is stored. At least one egress node receives marked and not marked packets, decodes and counts the overload from the marked packets in a counting interval. Congestion report messages are sent to ingress nodes where flows are terminated.

Abstract: A network node for reserving resources for data flows in a communication network. The node detects a request for resource reservation for a new data flow and computes an admission test count based on descriptors of the new data flow and reservation counts, which represent reservation functions of descriptors of previously admitted data flows and which specify resources of the admitted data flows. The new data flow is admitted if the admission test count is smaller than a maximum allowable count. The reservation counts are then updated based on the descriptors of the new data flow. A plurality of admission formulas may thus be used to maintain aggregated reservation counts for data flows, the number of counts being independent from the number of flows.

Abstract: Embodiments of the present invention relate to network nodes and methods that allow for improved QoS control in a telecommunications network by providing combined reservation of transport resources and processing resources for a traffic flow. The amount of transport resources and the amount of processing resources required in connection with a traffic flow can be signaled in a signaling message from a sender node to a receiver node to enable reservation of appropriate amounts of processing resources as well as transport resources.
