Request。
Define an IE (information element): new definition 1 is entitled in RRC Connection Request
The Establishment Cause (setting up reason) of interRAT-Redirect.
Specification in agreement 3GPP TS36.311, the cause value of RRC Connection Request accounts for 3 ratios altogether
Spy, i.e. has 8 (3 powers of 2) to plant different indicated values, has only used 5 kinds therein in agreement, respectively
It is: emergency (urgent call), highPriorityAccess (high priority access request), mt-Access
(called access), mo-Signalling (caller signaling), mo-Data (caller data).Remaining 3 fingers
Indicating value be spare1 (standby 1) spare2 (standby 2) spare3 (standby 3), i.e. reserved do not use.
Utilize wherein 1 in these 3 reserved bit, 1 entitled interRAT-Redirect's of definition
Establishment Cause。
Trigger UE to report and set up RRC Connection Request's that cause value is interRAT-Redirect
Mechanism is: UE initiates combined EPS/IMSI attach, receives the Attach Accept that MME issues
In the Attach result that carries be EPS only, then triggering UE and initiating cause value is interRAT-Redirect

In time range, forbid that the UE residing in 2/3G network initiates to the gravity treatment of 4G network, redirects or cut
Change of current journey, i.e. within the T-Prohibit time, limits UE and resides in 2/3G network, to guarantee this terminal CS
Business normal.This intervalometer arranges the longest, then to reside in 2/3G network the longest for UE, its CS voice
Business is the most secure, but speed perception can be impacted；This intervalometer arranges the shortest, then UE can frequently weigh
Choosing, redirecting or switch 4G network, speed perception more preferably, but can be encountered and combine the recessive failure of attachment
4G community probability can be higher, thus CS business can be impacted.In being embodied as, the time of this intervalometer
Length can carry out relative set, the invention is not limited in this regard according to actual needs.
The mechanism that the intervalometer T-Prohibit of triggering UE comes into force is: UE initiates cause value and is
