20090323965 | Systems and Methods for Monitoring Performance of a Communication System - Monitoring the performance of communication systems is an important part of network operations. In one aspect the invention provides a method for monitoring the performance by collecting data pertaining to a mobile terminal accessing the system. In some embodiments, the method includes receiving an identifier for identifying the mobile terminal; using the identifier to detect the UE accessing the network via an access point; and in response to detecting the UE accessing the network, transmitting to the access point a message comprising an encrypted version of the identifier with a command to initiate the collection of data pertaining to the mobile terminal. | 12-31-2009 |
20100275086 | Prescheduled Retransmission for Initial Establishment - The invention relates to a method for a wireless communications network for data packet communication, the communications network comprises a user equipment (UE) and a transceiver node (eNodeB). The user equipment (UE) and the node (eNodeB) intercommunicates over an air interface communication link. The user equipment (UE) transmits a first message (MSG3) in a first scheduled transmission in a random access procedure during setup of the communication link. The invention is characterized in that the first message is transmitted in a first sub frame (TTI=3) and in a second sub frame (TTI=4; TTI=5) within a first roundtrip time (RTT) in a first HARQ-process triggered by the transmission of the first message in the first sub frame (TTI=3). The invention also relates to a wireless communications network for data packet communication. | 10-28-2010 |
20110110240 | ADJUSTMENT OF RADIO DETECTION LEVEL FOR REQUEST SIGNALS BASED OBSERVED FALSE DETECTION - The present invention relates to receiving access signals from a plurality of terminals over a radio channel and in particular to determining a detection threshold level on the radio channel. A detection threshold level should balance the risk of missed detections to the risk of false detections. A problem in finding an equilibrium threshold is the radio environment, with noise and interference, change and then also the radio false detections or missed detections change. According to the present invention some access signals can be identified as being not assigned and therefore not being in use, and any detection of a non-used signal is identified as a false detection. By monitoring the ratio of false detections vs. correct detections the threshold level for detection is tuned into an equilibrium level, and that is adapted to the changing radio environments. In addition the detection threshold level for access signals detection threshold for data and/or control signalling may be adjusted in relation to the access signal threshold level. | 05-12-2011 |
20110222432 | MONITORING INDIVIDUAL DATA FLOW PERFORMANCE - The performance of a network, such as a mobile communications network, having multiple network nodes can be monitored. In a first network node, certain data flows passing through the node are tagged by adding a performance management identifier. In a second network node, statistics relating to data flows containing the performance management identifier are aggregated, and the aggregated statistics are reported to a management node of the communications network. This allows for the gathering of accurate statistics relating to specific types of data flow, such as data flows to specific types of user equipment or containing specific types of data, even though the second node, in which the statistics are generated, cannot itself distinguish between the different data flows. | 09-15-2011 |
