Ordering information, device class number (Device Classification Number).
Step S402, MTC device carries out first network attachment, carries out first network registry.
MTC device sends registration message to core network element, and core network element confirms authenticating result to MTC SERVER.
Step S403, after MTC device normal registration, according to the DRX cycle that core network element (such as base station) is sent, with MTC
The dormancy strategy of SERVER carries out periodicity SLEEP.
MTC device sends the DRX cycle in paging message according to network, carries out periodicity SLEEP, disconnects network connection,
Releasing network resource, while terminal power consumption is reduced, it is whole only in network UE power saving wakeup timer time-out
End, which wake up, checks the need for data connection or signaling connection.
Step S404, MTC device determines whether that business datum reaches or the length of one's sleep (SLEEP TIMER) is overtime,
Prepare, using data, to ask network connection.
When MTC device has data, either signaling will be sent or UE electricity-saving wake-ups timer (UE power saving
Wakeup timer) time-out, then terminal waken up (WAKE UP) pattern, ask network connection, prepare data sending.
Second embodiment
