In addition to the state transitions shown in Figure 4.2.1-1 and Figure 4.2.1-2, there is support for connection release with redirection information from E-UTRA RRC_CONNECTED to GERAN, UTRAN and CDMA2000 (HRPD Idle/ 1xRTT Dormant mode).

TDL与TDS之间的互操作包括：重选、切换和重定向三种方式。

TDL和GSM之间的互操作包括：重选、切换、小区改变命令（CCO）和重定向四种方式。

17.1小区改变命令（CCO）

CCO的目的是在源RAT的控制下，将一个UE和源RAT之间的连接转移到另一个RAT中。 CCO在E-UTRAN侧，使用消息MobilityFromERTRACommand消息触发，该消息指出了UE需要进行CCO，而非切换。

NACC：Network AssistedCell Change，网络辅助小区改变，是CCO的一种优化。他与CCO的主要区别是CCO只提供目标GERAN小区的频点和ID，而NACC除了提供目标小区的频点和ID之外，还提供一些GERAN小区的系统消息，这样UE可以快速进入目标小区，不用花时间读目标小区的系统消息。

17.2重定向

重定向是指在RRCrelease中，写的目标小区（TDS或GSM小区）的频点和ID信息，实现到目标小区的驻留。
