20160027449 | PYRAMID VECTOR QUANTIZER SHAPE SEARCH - An encoder and a method therein for Pyramid Vector Quantizer, PVQ, shape search, the PVQ taking a target vector x as input and deriving a vector y by iteratively adding unit pulses in an inner dimension search loop. The method comprises, before entering a next inner dimension search loop for unit pulse addition, determining, based on the maximum pulse amplitude, maxamp | 01-28-2016 |
20150304949 | METHOD, NETWORK DEVICE, COMPUTER PROGRAM AND COMPUTER PROGRAM PRODUCT FOR DETERMINING A SET OF POWER STATE PARAMETERS - According to a first aspect, it is presented a method, performed by a network device, for determining a set of power state parameters at least partly defining when a wireless terminal is to be in an active state or a power saving state. The method comprises the steps of: obtaining at least one traffic characterisation parameter; for each traffic flow, simulating a plurality of sets of power state parameters; obtaining at least one operational traffic characterisation parameter; associating the operational traffic with a selected traffic flow; finding an applicable set of power state parameters by finding a set of power state parameters with a low cost, wherein the set of power state parameters are associated with the selected traffic flow; and sending the applicable set of power state parameters to the wireless terminal in operation. A corresponding network node, computer program and computer program product are also presented. | 10-22-2015 |
20150236920 | METHOD AND APPARATUS FOR DETERMINING CONNECTION INFORMATION OF A LINK - A method and apparatus is provided for determining connection information of a link between a first port on a first network element and a second port on a second network element. Bidirectional Forwarding Detection discriminator values are defined for both the first port and the second port, BFD signals are sent over the link, and a link connection profile is produced containing the first and second BFD discriminator values. The link connection profile is notified to a network management system, which may then update the network topology with the link connection information. | 08-20-2015 |
20150139098 | Frequency Offset Estimation Between a Mobile Communication Terminal and a Network Node - There is disclosed a method for estimating a frequency offset between a mobile communication terminal and a network node. The method is based on processing, by means of a matched filter, a preamble sequence for random access received on a physical random access channel, PRACH. Thus the method is preferably applied in the Evolved Universal Terrestrial Radio Access (E-UTRA) network. In the matched filtered preamble sequence two peaks are determined and the frequency offset is based on a ratio of the two peaks. A corresponding network node, computer program and computer program product are also presented. The network node is preferably performed in a network node of the type eNodeB, E-UTRAN NodeB, also known as Evolved NodeB. | 05-21-2015 |
20140119193 | METHOD FOR DYNAMIC LOAD BALANCING OF NETWORK FLOWS ON LAG INTERFACES - A method is implemented by a network element to improve load sharing for a link aggregation group by redistributing data flows to less congested ports in a set of ports associated with the link aggregation group. The network element receives a data packet in a data flow at an ingress port of the network element. A load sharing process is performed to select an egress port of the network element. A check is whether the selected egress port is congested. A check is made whether a time since a previous data packet in the data flow was received exceeds a threshold value. A less congested egress port is identified in the set of ports. A flow table is updated to bind the data flow to the less congested egress port and the data packet is forwarded to the less congested egress port. | 05-01-2014 |
