求教：LTE中RRC连接释放的原因值会是什么?

please find the asn.1 definition in R10 so far:

ReleaseCause ::= ENUMERATED {loadBalancingTAUrequired,
other, cs-FallbackHighPriority-v1020, spare1}

根据36331协议 R9版本 只有两种:loadBalancingTAUrequired和other

ReleaseCause ::=             ENUMERATED {loadBalancingTAUrequired,
                                                                                                       other,spare2,spare1}
