RRCconnecitonReestablishmen和RRCconnecitonReconfiguration两个信令有啥不同？Reconfiguration一般应用在哪些场景下？谢谢。
RRCconnecitonReconfiguration是无线资源重新配制(调试)...
RRCconnecitonReestablishmen是RRC链路出现异常时，需要重建The purpose of this procedure is to re-establish the RRC connection, which involves the resumption of SRB1 operation,
the re-activation of security and the configuration of only the PCell.
A UE in RRC_CONNECTED, for which security has been activated, may initiate the procedure in order to continue the
RRC connection. The connection re-establishment succeeds only if the concerned cell is prepared i.e. has a valid UE
context. In case E-UTRAN accepts the re-establishment, SRB1 operation resumes while the operation of other radio
bearers remains suspended. If AS security has not been activated, the UE does not initiate the procedure but instead
moves to RRC_IDLE directly.
RRCconnecitonReconfiguration是对现有的RRC进行配置，具体用法为：
The purpose of this procedure is to modify an RRC connection, e.g. to establish/ modify/ release RBs, to perform handover, to setup/ modify/ release measurements, to add/ modify/ release SCells. As part of the procedure, NAS dedicated information may be transferred from E-UTRAN to the UE.
