Because of value, the reason for adhering to refusal value is used for the reason for table attachment is refused；
Wherein, the reason for attachment in the attachment refuse information is refused value is used to trigger the terminal based on described
2nd LTE cells perform attaching process.
That is, the reason for attachment of the terminal in the exhausted message of attachment is refused value determines that attachment is lost
Lose, so as to perform attaching process based on the 2nd LTE cells, i.e., sending the second attach request to the 2nd LTE cells disappears
Breath, to initiate attaching process, that is, performs step 103.
Step 103：The second Attach Request message that the terminal is sent based on the 2nd LTE cells TAC is received, to the end
End sends attachment success message；
Here, second Attach Request message is sent after the terminal selects the 2nd LTE cells；Described
The TAC of two LTE cells and the TAC of the first LTE cells are differed.
In one embodiment, after receiving the second Attach Request message that the terminal is sent, the terminal is authenticated,
Obtain authentication successful result；
Default EPS bearing (defaultEPSBearer) is established for the terminal, to complete attaching process；
Attachment success message is sent to the terminal.
Wherein, EPS carrying the transmission data and/or signaling etc. of foundation.
During practical application, in order to verify the validity of prioritization scheme, can also detect the terminal receive attachment refusal disappear
Behavior after breath, further to verify the validity of prioritization scheme and reasonability.
Based on this, in one embodiment, after sending attachment refuse information to the terminal, judge whether received in preset duration
The second Attach Request message sent to the terminal；
If the terminal transmission is received in preset duration second adheres into request message, sent to the terminal
Adhere to success message.

Wherein, in three timers involved in this application embodiment, timer 1, timer 2 and timer are respectively designated as
3。
The detection method of this application embodiment network insertion result, as shown in figure 3, comprising the following steps：
Step 301：Trigger UE starts and start register flow path to LTE cell 0；
Here, analog platform needs to configure power of the power higher than LTE cell 1 of LTE cell 0, and LTE cell
1 power is higher than the power of other cells, starts to be registered on LTE cell 0 to trigger UE.
Specifically, it is small to LTE cell 0 to send RRC connection request (i.e. RRC Connection Request) message by UE
The corresponding base station in area, after base station receives the RRC Connection Request message of UE transmissions, completes RRC with UE and is connected foundation
(RRCConnectionSetup) flow.
Step 302：After RRC connections are successfully established, UE sends attach request (i.e. to 0 corresponding base stations of LTE Cell
Attach Request) message, UE is authenticated, to be attached to 0 cells of LTE Cell；
Here, a kind of abnormal refusal situation is simulated by emulation platform at this time, attachment refusal (i.e. Attach is sent to UE
Reject the reason for) message, carrying (cause) value is EPS and non-EPS services not allowed, represents institute
Some EPS services and non-EPS services are rejected, and Fig. 4 is the schematic diagram of the cause values shown by computer display.
Step 303：After sending attachment refusal (Attach Reject) message to UE, analogue system monitors the behavior of UE, holds
The duration of continuous timer1；
Specifically, the access request that detection UE is abandoned on LTE Cell 0 is attempted, and will not be accessed on GSM 0
Request, performs step 304 afterwards.
When UE does not abandon access request on LTE Cell 0 and attempts in the duration in timer 1, or attempt in GSM
Access request is carried out on 0, then illustrates that prioritization scheme fails.
Step 304：Analogue system monitors the behavior of UE, after 1 time-out of timer Timer, before 2 time-out of Timer,
Detection：UE starts to carry out access request on LTE Cell 1；
Here, if be not detected by UE after 2 time-out of Timer carries out access request on LTE Cell 1, optimization side is illustrated
Case fails.
Step 305：After access request is received, analogue system allocation of downlink resource (including acquiescence ESP carryings), completes UE
Register flow path on LTE Cell 1, and the duration of timer 3 is monitored, determine that UE can be stably resident on an LTE network, it
Step 306 is performed afterwards；
When UE can not stably be resident explanation prioritization scheme failure on an LTE network in the duration in timer 3.
Step 306：Analogue system improves the transmission power of GSM 1；
Step 307：Analogue system detects that UE will not initiate the access request to GSM 1, still can stablize and reside in LTE
On network.
Illustrate that UE is successfully accessed LTE network, prioritization scheme success at this time.Certainly, when detect UE initiate connecing to GSM 1
When entering to ask, illustrate that prioritization scheme fails.
