GRR实体的疑惑

cxin2

这是GRR的spec中的一段，其中的"short"不明白什么意思？有大侠了解吗？谢谢
Downlink TBF Establishment / using two message IMMEDTIATE ASSIGNMENT
(RR1)
RR is reading CCCH. After receiving both parts of an IMMEDIATE ASSIGNMENT for a downlink assignment it passes these
messages to GRR.
(GRR1)
If GRR gets two suitable IMMEDIATE ASSIGNMENT, GRR configures TBF.
(PL1)
PL prepares a TBF as described in PPC_TBF_CONFIGURE_REQ. [I][U]Short[/U][/I] before PL starts to use the TBF-assignment, PL sends a
PPC_TBF_CONFIGURE_CNF (here immediately, because here is no TBF-starting time included).
(GRR2)
GRR is waiting for a incoming data block, control message or ready indication from PL.
(PL2)
PL is searching valid blocks on the assigned resources.[upload=jpg]UploadFile/2006-2/06211@52RD_未命名.JPG[/upload]

<P>楼主从那里搞来的TI的协议文档啊? 这里的short是指在TBFconfig到L1之前, 就吧CNF返回给GRR了.</P><P>要是真想研究GRR协议, 建议你去看GSM0408/0460</P>
