&(GSM 05.02 version interleaved blocks repeats itself e.g. 51.
viii) "Interleaved block TDMA frame mapping" defines, within the parentheses, the TDMA frames used by
each interleaved block (e.g. 0..3). The numbers given equate to the TDMA frame number (FN) modulo the
number of TDMA fram Therefore, the frame is utilized when:
TDMA frame mapping number = (FN)mod repeat length given
Where there is more than one block shown, each block is given a separate designation e.g. B0, B1. Where diagonal
interleaving is employed then all of the TDMA frames included in the block are given, and hence the same TDMA
frame number can appear more than once (see GSM 05.03). Also, for E-TCH/F28.8, E-TCH/F32.0 and E-TCH/F43.2,
the same frame number appears for the inband signalling message and for several interleaved blocks. It should be noted
that the frame mapping for the SACCH/T channel differs according to the timeslot allocated in order to lower the peak
processing requirements of the BSS.

iv) The parameter in the BCCH (see subclause be reduced by the number of blocks reserved for access grant messages.
If system information messages are sent on BCCH Ext, BS_AG_BLKS_RES shall be set to a value greater
than zero.
Table 5 of clause 7 defines the access grant blocks and paging blocks available per 51-multiframe.
vi) Another parameter in the BCCH, BS_PA_MFRMS indicates the number of 51-multiframes between
transmissions of paging messages to mobiles in idle mode of the same paging group. The "available" paging
blocks per CCCH are then those "available" per 51-multiframe on that CCCH (determined by the two above
parameters) multiplied by BS_PA_MFRMS. Mobiles are normally only required to monitor every Nth block
of their paging channel, where N equals the number of "available" blocks in total (determined by the above
BCCH parameters) on the paging channel of the specific CCCH which their CCCH_GROUP is required to
monitor. Other paging modes (e.g. page reorganize or paging overload conditions described in GSM 04.08)
may require the mobile to monitor paging blocks more frequently than this. All the mobiles listening to a
particular paging block are defined as being in the same PAGING_GROUP. The method by which a
particular mobile determines to which particular PAGING_GROUP it belongs and hence which particular
block of the available blocks on the paging channel is to be monitored is defined in subclause
