预清空的设置是设置哪种信道可以被预清空;
0
All on-demand PDCHs are possible to preempt.
1
On-demand PDCHs not used for Dual Transfer Mode (DTM) are possible to preempt.
2
On-demand PDCHs not used for Streaming are possible to preempt.
3
On-demand PDCHs not used for DTM nor for Streaming are possible to preempt.
4
On-demand PDCHs that are not essential are possible to preempt.
5
On-demand PDCHs that are not essential nor DTM PDCHs are possible to preempt.
6
On-demand PDCHs that are not essential nor Streaming PDCHs are possible to preempt.
7
On-demand PDCHs that are not essential nor DTM nor Streaming PDCHs are possible to preempt.
8
Idle on-demand PDCHs are possible to preempt.
在TAB中开通预清空的功能命令如下：（如果爱立信还没有在BSC打补丁屏蔽修改TAB表）
SYPACSW=***,ACCESS=ENABLED;
DBTRI;
DBTSC:TAB=AXEPARS,SETNAME=CME20BSCF,NAME=PREEMPTION;,VALUE=3;
DBTRE:COM;
SYPAC:ACCESS=DISABLED;
如果打了补丁此命令无效,需要向爱立信购买权限。

在R12中，如果PDCHPREEMPT为空,说明在TAB 表没有打开PDCHPREEMPT功能,此时所有的动态信道都可以被清空的.
而GPRSPRIO参数只是设定在各种算法中对动态信道如何处理,是当作忙信道还是空闲的信道计算.
GPRS priority
This parameter controls whether preemptable on-demand Packet Data Channels (PDCHs) will be treated as idle or busy for functions: Dynamic Half Rate (HR) allocation and TCH packing, Cell Load Sharing, Subcell Load Distribution and GSM - UMTS Cell Reselection and Handover.
