Abstract
Official abstract text for this publication.
The problem of unsynchronized internal clocks of user equipments in a cellular communication system is addressed by a solution where a mechanism relying on a standalone clock function in user equipments is provided. Embodiments provide a network node that distributes a time reference to a user equipment (UE), and wherein the UE, using an internal clock function, time-stamps the logged measurements and/or events relative to the received time reference. When the UE has logged measurements the UE indicates to the network node that it has an available measurement log. The network node may then request several UEs to deliver their measurement log, respectively. The network node is then able to retrieve time stamped measurement information from the measurement log of each UE relative the sent time reference. Furthermore, the network node is then able to compare measurement information from each UE in a cell provided at the same time interval in all UEs.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in a user equipment for enabling processing of measurement data, the user equipment configured to communicate with a network node in a cellular communication system, the user equipment having a measurement log for storing measurement data and time reference information, the method comprising: receiving a time reference from the network node; starting an internal clock at the reception of the time reference; storing the time reference in th…
