20090054001 | Method and apparatus for determining latency and throughput of a data communication - The technology in this application determines the throughput over a data communication substantially as experienced by a user receiving the data. The determined throughput is substantially independent of the total amount of data transferred over the connection. This “active” throughput measure is divided into two parts to provide two performance measures: transfer throughput and latency. Latency corresponds to a time period needed to accomplish one or more functions associated with the data connection, like setting up and taking down the connection, during which payload type data to be transferred to an end user is not transferred. By identifying and removing the initial latency from the throughput determination for the data connection, the determined transfer throughput provides a more accurate measure of the throughput actually experienced by the end user. | 02-26-2009 |
20110026408 | ERROR RATE MANAGEMENT - The invention deals with the adjustment of the nominal target error rate for transmission of data from a priority queue to a new predetermined target error rate depending on the state of the priority queue. Usually, the adjustment to the new predetermined target error rate will be to a predefined lower target error rate based on states of the priority queue, such as amount of data in the priority queue, time passed since the latest transmission of data from the priority queue, whether the amount of data in the priority queue will fit into one transport block, whether the data unit to be transmitted for the priority queue is the first or last data unit in the priority queue and may also be based on the type of data stored in the priority queue. There may be more than one such priority queue. | 02-03-2011 |
20120093001 | Methods and Apparatus for Adapting Network Characteristics in Telecommunications Systems - Methods in a network node, such as a radio base station (RBS) node or a radio network control (RNC) node, for adapting network characteristics in a telecommunications system are provided. A plurality of entities indicative of the performance of the network are measured simultaneously, by means of a single table, and one entity is selected as main entity. The measurements are stored within main entity ranges and a correlation of the measurements is performed to determine a relationship among the entities with main entity range(s). The result(s) of the correlation is used to adapt network characteristics for optimizing the network. Related network nodes are also discussed. | 04-19-2012 |

20130250873 | PREDICTIVE EUL SCHEDULING BASED ON SERVICE AWARENESS - The present invention relates to a method and device for scheduling transmission of data of terminals in a cell. To this end, information is acquired indicating type of communication service for which a first terminal is to be scheduled. Then, the first terminal and at least a second terminal in the cell is scheduled for transmission of data on the basis of the acquired information indicating the type of communication service for which the first terminal is to be scheduled, the at least second terminal being scheduled for data transmission in time periods between data transmissions of the first terminal. | 09-26-2013 |
20140301225 | NON-CONGESTIVE LOSS IN HSPA CONGESTION CONTROL - A method and a network node for increased utilization of a transport network link over a transport network of a HSPA system. The method comprises detecting a data packet loss in receiving a data packet flow, and detecting data delay information of data packets as received. The method also comprises determining if the detected data packet loss comprise non-congestive data packet loss, based on the detected data packet loss and the detected data delay information. In addition, the method comprises, when the detected data packet loss comprises non-congestive data packet loss, for a pre-determined time period, omitting to perform a congestion action affecting the data packet flow. By determining whether a data packet loss is non-congestive or not, an unnecessary reduction of the bitrate over the transport network can be omitted. | 10-09-2014 |
20140307547 | FLOW BASED PACKET MANIPULATION CONGESTION CONTROL - This disclosure relates to a Radio Network Controller, RNC, a base station, and to methods therein. By extracting information from one or more flows of Protocol Data Units, PDUs, which information is accessible on a certain protocol layer only, congestion control is enabled and performed on another protocol layer based on said information. | 10-16-2014 |
