| 20100056151 | Reducing Buffer Overflow - A method of reducing buffer overflow in a cellular radio network caused by a transfer of data from a buffer in a first cell to a buffer in a second cell when a handover of mobile equipment from said first cell to said second cell occurs. The method comprises temporarily increasing an amount of temporary buffer space required to handle data transferred from the buffer of the first cell to the buffer of the second cell. In one embodiment of the method, prior to increasing the amount of temporary buffer space, the amount of temporary buffer space required is calculated. | 03-04-2010 |
| 20100131664 | Buffer transfer in a communications network - A method and apparatus for transferring buffer data from a first network node to a second network node during a mobile handover between cells. In order to improve the speed at which buffer data is transferred during a handover, a connection using a congestion control protocol is established between the two nodes prior to the handover. Dummy data is sent over this connection, in order to approach or reach the available data transfer rate, and at the handover, the dummy data is replaced with buffer data. | 05-27-2010 |
| 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 |
| 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 |
| 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 |
| 20110149730 | TECHNIQUE FOR IMPROVING CONGESTION CONTROL - A technique for controlling data transmission over a connection employing congestion control is provided. The technique comprises two basic aspects: Detecting a decrease of Round Trip Time in respect of the connection, wherein the detection is facilitated by comparing a short-term Round Trip Time average with a long-term Round Trip Time average ( | 06-23-2011 |
| 20110173165 | MANAGEMENT OF PERFORMANCE DATA - A method of handling performance data comprising a set of events is described. An event record for each event is stored as a set of blocks, each block containing one or more attributes of the event. The storage space occupied by each event record in is then reduced in discrete steps, each step including a reduction process that reduces the size of one of the set of blocks. This enables the provision of intermediate records between events and counters so that new event records contain complete details of their event, older event records contain less information, and even older event records may contain only high-level (counter) information. | 07-14-2011 |
| 20110202593 | FOCUSED SAMPLING OF TERMINAL REPORTS IN A WIRELESS COMMUNICATION NETWORK - A performance management system and method are described herein that can control which client terminal(s) (e.g., mobile terminal(s)) are to provide Quality of Experience, QoE, report(s) and also control a level of detail for the requested QoE report(s). | 08-18-2011 |
