请问GMM-REGISTERED.SUSPENDED (GSM only)和GMM-DEREGISTERED.SUSPENDED (GSM only)有什么差别啊？


协议上说明：
GMM-REGISTERED.SUSPENDED (GSM only)
The MS shall enter this substate when entering dedicated mode and when the MS limitations makes it unable to communicate on GPRS channels... In this substate, no user data should be sent and no signalling information shall be sent. The MS shall leave this substate when
leaving dedicated mode.


GMM-DEREGISTERED.SUSPENDED (GSM only)
The MS shall enter this substate when entering dedicated mode and the MS limitations make it unable to communicate on GPRS channels. The MS shall leave this substate when
leaving dedicated mode.


看不出来差别啊。
