Fig. 1 be network insertion result provided in an embodiment of the present invention detection method schematic flow sheet, the skill of the present embodiment
During art scheme is applied to terminal using the execution GSM network access of default prioritization scheme, as shown in figure 1, the network
The detection method of access result includes：
Step 101：Receive the first Attach Request message that the terminal is sent；
Wherein, first Attach Request message is sent after the terminal selects the first LTE cells.
It is worth noting that, it is that terminal completes wirelessly with network that the premise of attaching process is performed between terminal and network
Process is established in resources control (RRC, Radio Resource Control) connection.
Specifically, the RRC connection request that terminal is sent to network side, the lateral terminal of network return to RRC connection establishment responses
Message；Terminal sends RRC connection setup complete messages to network side.
That is, before the terminal and network side carry out attaching process, the terminal needs to carry out with network side
Random access procedure.
More specifically, random access procedure can include：Terminal sends random access request message (Msg1) to base station, its
It is middle to carry leading (preamble)；After base station receives message, accidental access response message (Msg2) is sent to terminal；Terminal receives
After message, send RRC connections to base station and establish request message (Msg3)；After base station receives message, send RRC connections to terminal and build
Vertical message (Msg4)；Terminal sends RRC connection setup complete messages (being sent by SIB1) to base station.
Step 102：To the terminal send for refuse the first LTE cells TAC corresponding to LTE network it is all
EPS is serviced and the attachment refuse information of non-EPS services；
Here, during practical application, after LTE base station receives the first Attach Request message of terminal transmission, institute is forwarded to MME
State the first Attach Request message.The attachment relevant treatment in LTE network is carried out to the terminal by MME and HSS, including authenticate,
Location management etc., to complete to register in LTE network；Meanwhile terminal is also needed in other networks such as WCDMA/GSM/CDMA
The related corresponding log-on message of network operation, worked so terminal is actual in LTE network, but also have registration in other networks
Information.So that is, after MME receives Attach Request message, can forward location updating (LocationUpdate) message to
Mobile switching centre (MSC) in 2G/3G networks, and handled by attaching position register (HLR)；In this process,
When the movement of terminal or other reasonses cause LTE network corresponding to the first LTE cells to provide EPS services and non-EPS
During service, MME sends attachment refuse information by LTE base station to terminal.
Wherein, tracking area is LTE/ System Architecture Evolutions (SAE, System Architecture Evolution) system
The concept newly set up for the location management of terminal.It is defined as UE need not more new demand servicing move freely region.Tracking area
Function can be divided into paging management and location updating management to realize the management to terminal location.Terminal is registered by tracking area and accused
Know core net (EPC) tracking area of itself.
When terminal is in idle condition, core network is able to know that the tracking area where terminal, while when in the free time
When the terminal of state needs to be paged, it is necessary to paged in all cells for the tracking area that terminal is registered.Tracking area is small
The configuration of area's level, multiple cells can configure identical tracking area, and a cell can only belong to a tracking area.
The EPS services can be understood as the data service of online, be the service of LTE network；Correspondingly, the non-EPS
Service can be understood as the service of 2G/3G networks.
Wherein, in one embodiment, encapsulation attachment refuse information, it is described to adhere in refuse information the original for carrying attachment refusal
Because of value, described the reason for adhering to refusal, is worth for characterizing the reason for attachment is refused；
Wherein, the reason for attachment in the attachment refuse information is refused is worth for triggering the terminal based on described
GSM cell performs attaching process.
That is, the reason for attachment of the terminal in the exhausted message of attachment fails value determines that attachment is lost
Lose, so as to perform attaching process based on the GSM cell, i.e., send the second Attach Request message to the GSM cell, to initiate
Attaching process, that is, perform step 103.
Step 103：The second Attach Request message that the terminal is sent is received, adheres to terminal transmission and successfully disappears
Breath；
Here, second Attach Request message is sent after the terminal selects the GSM cell.The GSM is small
The TAC in area is identical with the TAC of the first LTE cells.
In one embodiment, after receiving the second Attach Request message that the terminal is sent, the terminal is authenticated,
Obtain authenticating successful result；
For the terminal distribution downlink resource, to complete access procedure；
Attachment success message is sent to the terminal.
Wherein, the downlink resource of distribution is used to transmit data and/or signaling etc..
During practical application, after base station sub-system (BBS) receives the access request message (channel request message) of terminal transmission,
For terminal distribution dedicated channel, after then BBS receives the authentication request (i.e. the second Attach Request message) of terminal transmission, by message
MSC is transmitted to, the terminal is authenticated by MSC and VLR Visitor Location Register (VLR), to complete attaching process, Zhi Houfen
With corresponding downlink resource, to complete access procedure.
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, to after the transmission attachment refuse information, judge institute whether is received in preset duration
State the second Attach Request message of terminal transmission；
If receiving the second Attach Request message that the terminal is sent in preset duration, sent to the terminal attached
Success message.

Detect whether the terminal is initiated in the first preset duration to the first LTE cells or to the 2nd LTE cells
Access request；The TAC of the 2nd LTE cells is identical with the TAC of the first LTE cells；
When detecting the access do not initiated in the first preset duration to the first LTE cells or to the 2nd LTE cells
During request, judge whether the terminal receives the second Attach Request message that the terminal is sent in the second preset duration.
Here, when detecting in the first preset duration initiate to the first LTE cells or to the 2nd LTE cells
During access request, illustrate that prioritization scheme fails.
Certainly, when the terminal does not receive the second Attach Request message of the terminal transmission in the second preset duration
When, also illustrate that prioritization scheme fails.
During practical application, first preset duration and the second preset duration can be real by way of setting timer
It is existing；Specifically, first timer is set, and whether the detection terminal is initiated to described first before first timer time-out
LTE cells or the access request to the 2nd LTE cells；Second timer is set, detected when before first timer time-out
When not initiating to the first LTE cells or the access request to the 2nd LTE cells to the terminal, in the second timer
Whether the detection terminal receives the second Attach Request message that the terminal is sent before overtime.Wherein, the mesh of timer is set
Be avoid detection overlong time.
Wherein, the duration of timer can be arranged as required to.
Step 104：Resident state of the terminal in the GSM cell is detected, and the end is determined based on testing result
Whether end is successfully accessed GSM network.
Here, the TAC of the GSM cell is identical with the TAC of the first LTE cells.
In one embodiment, at step 104, when detecting that the terminal can reside in the GSM cell, it is determined that
The terminal is successfully accessed GSM network, further illustrates prioritization scheme success.
Certainly, when detecting that the terminal can not reside in the GSM cell, the terminal access GSM nets are illustrated
