1Cell Radio Network Temporary Identity (C-RNTI) identifies an UE uniquely within one celland
is assigned by the SRNC(=CRNC). It is used on DTCH and DCCH in uplink, may be used on DCCH in downlink and is used on DTCH in downlink when mapped onto common transport channels except when mapped onto the DSCH transport channel.0Q4G9F1S.L5^/G

UTRAN Radio Network Temporary Identity (U-RNTI) uniquely identifies the UEwithin the UTRAN,mscbsc 移动通信论坛拥有30万通信专业人员，超过50万份GSM/3G等通信技术资料，是国内领先专注于通信技术和通信人生活的社区。:3W;I.G3
because the SRNC-Id is included. It consists of S-RNTI and SRNC-Id and is assigned/rleased upon
The SRNC Radio Network Temporary Identity (S-RNTI) uniquely identifies an UE in the SRNS (e.g. in RNSAP messages) and is assigned by SRNCfor a RRC-connection establishment. A S-RNTI is discarded, if the RRC connection is released or when the SRNC changes -A0x
The Drift RNC Radio Network Temporary Identity (D-RNTI) uniquely identifies an UE in RNSAP messages from SRNC to DRNC and is assigned by DRNC.
RNTI之所以叫无线网络临时标识，是RAN区别于CN中IMSI,TMSI,IMEI而言的。U-RNTI=S-RNTI+SRNC ID（32bit），C-RNTI（16bit），当在CELL-FACH时，对下行来说，2者其实没什么太大区别，用哪个取决于网侧，但上行一定要用C-RNTI。可以看一下25.321中关于MAC头的描述，就知道如何使用2者了。在CELL-DCH时，由于是专用链路，网侧通过DL information for each radio link来标识UE即可
