来自UTRAN Command中的切换中Protocol errer与Inter-RAT protocol error之间的区别

Protocol error 主要来自TD端,在以下情况下TD将会report protocol errer:

1、如果NW在handover command中配置一个GSM消息列表,但是该列表为空;2、如果UE不支持ASN rel-6版本,但是网络配置了一个rel-6版本的RRC消息;3、如果UE接收到HO消息时不处于DCH状态;

Inter-RAT protocol errer主要来自GSM端,在以下情况会report Inter-RAT protocol errer:

1、如果GSM发现切换命令不正确,或者GSM RR在一个invalid 状态处理该消息;

If the IE "Inter-RAT message" received within the HANDOVER FROM UTRAN COMMAND message does not

include a valid inter RAT handover message in accordance with the protocol specifications for the target RAT, the UE

shall perform procedure specific error handling as follows. The UE shall:

           1> set the IE "failure cause" to the cause value "Inter-RAT protocol error";
