Appeal No. 2002-1130
Application 09/224,234
Invention
The invention relates to the selection of cells in a
multiple modulation cellular radio system. In particular, the
invention relates to the optimization of cell selection in which
each cell provides different features relating to the
transmission of information and the terminals have different
abilities to utilize these different features. See page 1 of
Appellants’ specification. The invention is particularly
advantageously realized in a GPRS system where the base station
broadcasts an MC bit. The MC bit can be for instance 0, if the
base station supports only the GMSK modulation, and 1 if the base
station supports the QAM modulation. According to figure 1, the
terminal 101 usually obtains the MC value as signaling from the
network 102. In this way, the terminal is notified of which
modulation methods are supported by those base stations within
the cell and allows the terminal to select those base stations
within the cell by utilizing the information about which
modulation methods are supported by those base stations within
the cell. See pages 6 and 7 of the Appellants’ specification.
