3.ncc_of_plmn_allowed=80h允许的网络色码
3.max_retran=3移动台发出信道请求的最大重发次数.RACH是一个ALOHA信道,网络允许移动台在收到立即指配消息前,发送多个信道请求,以提高接通率，但同时增加了RACH和SDCCH信道的负荷。
取值范围0－3。
0最大重发次数1
1最大重发次数2
2最大重发次数4
3最大重发次数7
10.radio_link_timeout=4GSM规范定义，移动台中有计时器S（T100），在移动台通话开始时被赋予一个初值，即无线链路超时（radio_link_timeout）。
BCCH上广播。
每当移动台无法正确解码一个SACCH消息（4个SACCHBLOCK）时，S减1。
每当移动台正确解码一个SACCH消息时，S加2。
但S不会超过radio_link_timeout定义的初值。
当S计数为零时，移动台放弃无线资源的连接，进入空闲模式。
发生一次掉话。
取值范围：
0－15（4-64SACCH）
3.tx_integer=12发送分布时隙数。
为克服ALOHA方式的缺点，tx_integer越大，RACH上发生碰撞的概率越小。
但是同时接续时间变长。
取值范围：
0to15（From3to50RACHslotsareusedtospreadthetransmission.）

10.reestablish_allowed=0是否允许呼叫重建0=enable
10.cell_reselect_hysteresis=4在不同位置登记区的小区重选滞后（0－14dB）。
值过大，移动台未能及时小区重选，人为造成小区的覆盖过大，移动台的通话干扰大，增加掉话的可能。
过小，则造成在不同位置登记区边界处频繁的位置更新，增加SDCCH的负荷。
3.rxlev_access_min=5移动台接入小区的最小电平值。
建议该值小于15。
电平值范围－110到－47dBm（如：
－105=－110+rxlev_access_min）
=-110+5
=-105dBm
