3GPP的RRC协议中，几种Extension扩展IE的区别是什么？
在3GPP TS36.331中，有好几种用于扩展的IE，如：criticalExtensionsFuture、nonCriticalExtension、lateNonCriticalExtension。 请问这三种IE分别用于什么内容的扩展？

我们知道RRC的版本是在不断的演进，不是一蹴而就的。所以很多信息都会未未来保留一部分扩展域，以便于协议的进一步演进。
可扩展协议，分为两部分： non-critical and critical extensions关键扩展和非关键扩展
对于non-critical critical extensions，终端接收后，可以忽略，或者认为是缺省值
对于critical extensions则RRC都要演进，如果终端无法正确解析关键扩展，则要拒绝词条消息。
即可用Critical and non-critical extensions消息有：
