6Burst type defines which type of burst as defined in clause 5.2 is to be used for the physical channel.
vii)"Repeat length in TDMA frames" defines how many TDMA frames occur before the mapping for the
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 <st1:chsdate w:st="on" IsROCDate="False" IsLunarDate="False" Day="30" Month="12" Year=".2) defines whether the common
control channels defined are combined with onto the same basic physical
channel. If they are combined then the number of available random access channel blocks (access grant
channel blocks and p see following), are reduced as defined in table 5 of clause 7.
&&& 5PCHAGCHNCHBCCH ExtTDMAmodulo 51block
v) The may share the same frame mapping (considered)
when combined onto a basic physical channel. The channels are shared on a block by basis, and
information within each block, when de-interleaved and decoded allows a mobile to determine whether the
block contains paging messages, system information messages or access grants. However, to ensure a mobile
satisfactory access to the system a variable number of the available blocks in each 51-multiframe can be
reserved for access grants and system information messages, only. The number of blocks not used for paging
(BS_AG_BLKS_RES) starting from, and including block number 0 is broadcast in the BCCH (see
subclause <st1:chsdate w:st="on" IsROCDate="False" IsLunarDate="False" Day="30" Month="12" Year=".2). As above the number of paging blocks per 51-multiframe considered to be "available" shall
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 <st1:chsdate w:st="on" IsROCDate="False" IsLunarDate="False" Day="30" Month="12" Year=".2.
vii)An MS which has its membership of at least one voice group or voice broadcast call group set to the active
state shall, in addition to monitoring the paging blocks as described above, monitor the notification channel,
NCH. This logical channel is always mapped onto contiguous blocks reserved for access grants, in a position
and number as given by the parameter NCP, defined in GSM 04.08, broadcast on the BCCH. The channel
may be present when a cell supports voice group or voice broadcast calls. The coding of the various structural
parameters described above in this subclause is not changed. Information within a block, when deinterleaved
and decoded, allows the MS to determine whether the block contains access grant messages or notification

cs怎样发无线电
我有更好的答案
单机是发不了的，网络游戏的话，按Z,X,C三个键发。同时BOT也会根据你说的话做出判断。
采纳率：8%
z x cradion1/2/3再选相应的内容。、甲方说的无线电是这个？
z,x,c,三个键，按完之后屏幕的左边会出现几条内容，再根据相应的数字就可以发出命令了，如果网络版的可以按K再对着插好的麦说话就好了。
LS瞎扯…单机也可以的、Z X C分别发出 声明 指令 回答
z 就可以了
按c键就可以选择了
