4.35.1 UTRAN Cell Unavailable Time

  1. This measurement provides the length of time the cell has been unavailable for each cause.
  2. DER (n=1)
  3. This measurement is obtained by accumulating the time periods when the cell is unavailable per cause. The possible cause could be “manual intervention”, “fault” , “transport problem” or “energy saving”. The sum of all supported per cause measurements shall equal the total time periods of cell unavailability. In case only a subset of per cause measurements is supported, a sum subcounter will be provided first.
  4. Each measurement is an integer value (in seconds). The number of measurements is equal to the number of supported causes plus a possible sum value identified by the .sum suffix.
