20100156622 | POLL-BASED ALARM HANDLING SYSTEM AND METHOD - A system and method of handling poll-based alarms. The method begins by detecting a high-priority problem in a network. Next, network elements in the network related to the high-priority problem are mapped. The mapping step includes grouping network elements into focus groups wherein each focus group includes network elements having the same alarm. The mapped network elements are then polled for alarms. The polled alarms of the network elements are then correlated and processed. | 06-24-2010 |
20100226278 | METHOD AND MONITORING COMPONENT FOR NETWORK TRAFFIC MONITORING - A technique for traffic monitoring in a network comprising monitoring components and a management center (MC) is described. A method implementation comprises the steps of selecting a first set of local identifiers from a larger second set of local identifiers, wherein the local identifiers are capable of providing a unique identification of a network connection at the first monitoring component, filtering network connections, allocating a local identifier of the first set of local identifiers to a network connection in case a filter condition applies during the filtering, checking associations of network traffic with local identifiers, and selectively monitoring network traffic associated with a local identifier from the first set of local identifiers. | 09-09-2010 |
20110078163 | METHOD AND SYSTEM FOR NETWORK FAULT MANAGEMENT - Methods of processing record data are presented, together with a Central Management Node for processing record data, and Management Subsystem DataBases for providing a record data set and matching record data. Triggered by service related network fault event, a key table comprising at least one key type is determined, based on a focus target record and related to the network fault event is determined, which key table is used in the step matching the at least one key with record data sets in determined Management Subsystem Databases. Matched results are merged, whereafter a service performance indicator may be determined, based on which a multi-layer water flow analysis of subsystem specific performance related indicators can be obtained. This analysis may be successfully used to reveal the location of the service related network fault. | 03-31-2011 |
20110080835 | TRAFFIC MONITORING BY LOWEST TRANSMISSION LAYER MARKING - A monitoring system is provided for monitoring transport of data through interconnected nodes for processing data packets in a communication system, wherein said data packets conform to a layered transmission protocol, the system comprising: (1) a marking node for marking a packet selected according to a marking rule by placing a monitoring indicator in the lowest protocol layer thereof, said data packet having a first number of protocol layers, (2) at least, one packet processing node for forming a data packet based or the marked packet, such that said formed data packet comprises a second number of protocol layers that is different from said first number of protocol layers and such that said indicator is in the lowest protocol layer of said formed data packet, and (3) a monitoring node for monitoring said transport of data on the basis of the indicators in data packets that have passed through the at least one packet processing node. | 04-07-2011 |
20110093592 | IMS PERFORMANCE MONITORING - A method and apparatus enabling performance monitoring in packet-switched IP networks such as those configured according to an IP multimedia subsystem, IMS, architecture. Performance is monitored by reconstructing selected control signaling sequences. The control signaling sequences, which are typically executed according a signaling protocol such as the Session Initiation Protocol, SIP, are reconstructed by parsing the contents of monitoring request headers configured, modified, and attached to control messages according to the present invention. The header includes at least an IMS monitoring ID field ( | 04-21-2011 |
20110222414 | METHOD AND APPARATUS FOR ACTIVE PROBING OF TUNNELED INTERNET PROTOCOL (IP) TRANSMISSION PATHS - A method, apparatus, and system in an IP-based mobile communication network for actively probing a tunneled transmission path from a base station such as an eNB to a core network. A UE-emulator emulates a User Equipment (UE) and provides emulated NAS signaling to a Probe Connection Control (PCC) unit in the base station, which establishes the tunneled transmission path by forwarding the NAS signaling received from the emulator toward the core network. The PCC stores associated communication endpoints and UE-assigned IP addresses. A Probe Traffic Control (PTC) unit within the base station utilizes the stored endpoints and IP addresses to generate probe traffic through the tunneled transmission path toward a probe server or another base station configured as a probe reflector. The probe reflector collects and reports path properties such as packet loss, delay, jitter, and throughput. | 09-15-2011 |
20120110012 | Estimating User-Perceived TCP Throughput - A passive network measurement based solution for estimating user-perceived TCP throughput in a mobile PS network is provided. Instead of direct detection of TCP bulk data periods and server side limitations, the diversity of TCP connection end-points on the Internet side is exploited. The TCP throughput at an interface of the mobile network from/to each server on the Internet side during a file/object transfer of bulk date periods is monitored and measured and the servers are ranked according to their throughput statistics. The top performing servers are grouped into classes by statistical algorithms. The throughput samples from the users towards the servers belonging to the top group of highest average throughput are averaged to obtain a proper estimation for the user-perceived TCP throughput. | 05-03-2012 |

20140086068 | Technique for Controlling and Handling Probe Tunnel Set Up - A technique for controlling and handling set up of a probe tunnel stretching from an access network node through a core network towards a core network node is described. In a method implementation, probe tunnel set up control comprises determining a First Fully Qualified Tunnel Endpoint Identifier (F-TEID) associated with the core network node and sending a probe tunnel set up instruction to the access network node. The instruction commands the access network node to locally set up the probe tunnel towards the core network node based on the F-TEID. | 03-27-2014 |
