Definitions

  • Ml block width equal to 2 xBo
  • Bo is a predefined elementary spectral width and M an integer greater than 1 chosen as a function of a maximum communication rate determined for the group of cells.
  • Each of the blocks is divided into a number 2 m of carriers of spectral width 2 xBo, m (i) being an integer depending on the block considered such that l ⁇ m (i) ⁇ M and representing a type of carrier.
  • the distribution of blocks and carriers in the allocated frequency band is identical for all cells in the group.
  • a defined logical channel is selected, according to the rate of said communication, as one or more elementary time intervals on one of the carriers.
  • carrier of type m (m ⁇ l).
  • the method according to the invention can be used with various types of modulations around these central frequencies.
  • the different types of modulation commonly used in cellular networks GMSK, QPSK,
  • Each value of RXQUAL is coded from 0 to 7 according to the value intervals where the observed bit error rate falls (respectively 0% -0.2% / 0.2% -0.4% / 0.4% -0 0.8% / 0.8% -6% / l 6% -3.2% / 3.2% -6.4% / 6.4% -12.8% / 12.8% -100 %).
  • the measurements made by the mobile station on the downlink are included in a message called MEASUREMENT-REPORT in GSM terminology.
  • the base station transmits these measurements to its BSC in a message called MEASUREMENT-RESULT, in which it also includes the measurements it has made on the uplink. These measurements are processed at the level of the BSC which performs the radio link monitoring functions. For more than details can be found in GSM Recommendation 05.08 (Draft pr ETS 300 578, 2 & edition, March 1995, ETSI).
  • Such a modification of the integer M and / or the integers m (i) results in a calculation of the priorities for the new distribution of the spectrum as a function of the priorities in force in the old distribution.
  • the BSC then assigns to each physical channel (carrier couple / simple or concatenated time interval) a new priority determined as follows: - if the carrier has a width included in the width of another carrier of the previous distribution, the priority of the new physical channel is taken equal to that of the physical channel formed by said other carrier and said time interval; and - if the carrier has a width covering the widths of several other carriers of the previous distribution, the priority of the new physical channel is taken equal to an average of the priorities of the physical channels formed respectively by said other carriers and said time interval.
  • This average can simply be an arithmetic average. It could also be a weighted average.
  • a frequency jump is carried out from block to block, with identical jump sequences for all the cells of the group.
  • the permuted block index i ' is then independent of n.
