Below on the basis of embodiment one or embodiment two, it is provided that several concrete examples:
As it is shown in fig. 7, the method described in this example includes:
Step 1: after receiving access calling, completes newly calling RRC and sets up；
Step 2:RNC obtains IMSI from RANAP signaling CommonID；
Step 3: detect described IMSI whether inside the IMSI-IMEITAC mapping table of RNC internal maintenance；
If it is not, then perform step 3a to step 3c；If it is, perform step 4 to arrive step 6.
Step 3a:RNC builds IdentityRequest；
Step 3b: receive the IdentityResponse signaling of handset replies；
Step 3c: update IMSI and IMEITAC mapping table；
Step 4: obtain IMEITAC corresponding to this IMSI；
Step 5: whether the IMEITAC of detection correspondence is within TD-SCDMA to the LTE IMEITAC blacklist redirected；
Step 6: perform the blind redirection of TD-SCDMA to LTE based on IMEITAC blacklist.
The flow process setting up described blacklist presented below, specifically includes:
Step 11: new calling accesses；Described calling can include various types of business such as LAC renewal, speech business, short message service and data service；When implementing, described calling also can be carried out acceptance judging by RNC.
Step 12:RNC is to the field IdleIntervalMeasureCapability in the RRCconnectionSetupComplete signaling extracting this time calling.
Step 13:RNC judges whether field IdleIntervalMeasureCapability is false；If not being false, then perform routine and redirect；If false, then perform step 14.
Step 14:RNC constructs identityRequest signaling, the mobile phone model of inquiry this time calling.
Step 15: receiving the IdentityResponse signaling of handset replies, described IdentityResponse signaling includes mobile phone model IMEITAC.
Step 16:RNC checks whether this IMEITAC has independent TD-SCDMA module and independent LTE module, because those have the terminal of independent LTE module field " IdleIntervalMeasureCapability " in RRCconnectionSetupComplete although being false, but still can automatically carry out the measurement to LTE network when TD-SCDMA network connected state；
Redirect if it is, RNC performs routine；If not false, then perform step 17.
Step 17:RNC updates TD-SCDMA to LTE and redirects IMEITAC blacklist, is added within blacklist by this IMEITAC.
In order to avoid mobile phone is when 3G and LTE is weak overlay area, cannot stablize resident behind the blind LTE of being redirected to community, cause and return TD-SCDMA network, table tennis between LTE and TD-SCDMA is caused to redirect, devising redirection penalty count and the punishment intervalometer of cell-level in this example, when each LTE mobile phone is redirected to LTE from TD-SCDMA is blind, the redirection enumerator N of cell-level subtracts 1 wherein, the initial value of described N may be configured as the integer more than 0, concrete such as 5.
When penalty count reduces to 0, this IMSI punishment intervalometer T starting cell-level is started timing by RNC, until punishment timer expiry, just allowing subscriber equipment to perform to redirect and make penalty count and punishment timer reset is initial value.Concrete as, when punishment intervalometer has not timed out, then this IMSI is not started blind redirection.
When redirecting penalty count N less than 0, then whether RNC inquiry punishment intervalometer T is out-of-date, if out-of-date, the redirection penalty count N of this IMSI is resetted by RNC, if not out-of-date, then continues waiting for (not carrying out blind redirection).
Prevent the flow process of soldier pang redirection as it is shown in figure 9, specifically include:
After step 31:RNC judges that this IMEITAC is in blacklist, check whether the blind redirection penalty count of this subscriber equipment is 0；Step 32 is performed as N=0；When N is more than 0, perform step 33；
Step 32: check that whether the punishment intervalometer of this subscriber equipment is overtime；
If punishment intervalometer does not have time-out, then carry out punishment action and do not carry out blind redirection；Herein, described punishment action refers to: stop relocating user equipment to the second network.
If punishment intervalometer T time-out, then perform step 33；Now, when implementing, if penalty count N is also resetted by time-out；Initial value after reset is equal to pre-determined number in above-described embodiment；
The LTE adjacent frequency point of step 33:RNC query configuration；
Step 34:RNC issues RRCconnectionRelease message, it is intended that the target LTE adjacent frequency point of redirection；
Step 35: when N-1 is not equal to 0, penalty count N subtracts 1；
Step 36: when N-1 is equal to 0, then restart punishment intervalometer for this subscriber equipment；
Step 37: mobile phone is redirected back to LTE network according to the frequency specified in RRCconnectionRelease message is blind.
In this example on the basis of the embodiment of the present invention, with penalty count, whether redirection number of times in the first appointment time is reached predetermined number of times further to count, to prevent subscriber equipment from redirecting back and forth between first network and the second network at short notice, and have and realize simple advantage.
