Using scheme provided in an embodiment of the present invention, message arrangement mistake can be redirected in IRAT cell switch process
Scene under, detect whether to receive the access request that terminal is sent after the GSM cell different from LTE network is switched to,
It determines whether to be successfully accessed network, the validity and reasonability of prioritization scheme used by final determining terminal can also
It is interpreted as feasibility and stability.
Fig. 1 is detection method flow diagram provided in an embodiment of the present invention, and the technical solution of the present embodiment is applied to eventually
During network insertion is held in end using preset prioritization scheme, as shown in Figure 1, the detection method includes：
Step 101：It is sent to the terminal and redirects message；
Here, the redirection message is after the endpoint registration to the first LTE cells and the signal strength of GSM cell
Higher than the first LTE cells signal strength when send.
The duration for redirecting message and carrying timer T320.
Here, during practical application, the duration of the timer T320 is located in the option for redirecting message, and be
Mistake, specifically, the duration of the timer T320 of carrying resides in the duration of GSM network (hereafter far more than pressure
The first described duration).
Wherein, the timer T320 is a timer in LTE network, and the meaning of expression includes：
Timing starts：Receive T320 (receiving the redirection message) or the UMTS lands face from another RAT to evolution
The cell selection (gravity treatment) of wireless access (E-UTRA) network, the effective time with dedicated priority are configured (in such case
It is lower to use remaining effective time)；
Timing stops：Into RRC_CONNECTED states, when Non-Access Stratum (NAS) requires to perform public land mobile network
Network (PLMN, Public Land Mobile Network) select when or to another RAT cell select (gravity treatment) when (
In this case other RAT run the timer)；
Time-out：It abandons and provides cell reselection priority information by special signal.
It is worth noting that, the premise that network side (LTE base station) sends redirection message to the terminal is that terminal is
Register flow path (connecting the process of foundation and attaching process comprising RRC is completed with network) is completed, it is small to reside in the first LTE
Area, and there are corresponding data services.
Wherein, process is established for RRC connections, including, the RRC connection request that terminal is sent to network side, network is lateral
Terminal returns to RRC connection establishment response 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,
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.
For attaching process, including：Terminal sends attach request to network side；After network side receives attach request, to end
End is authenticated, and obtains authentication successful result；Acquiescence evolved packet system (EPS) is established for terminal to carry, to complete to adhere to
Journey；Attachment success message is sent to terminal.
Wherein, during practical application, after LTE base station receives the Attach Request message of terminal transmission, to mobile management reality
Body (MME) forwards Attach Request message.The terminal is carried out in LTE network by MME and home signature user server (HSS)
Attachment relevant treatment, including authentication, location management etc., to complete to register in LTE network；Meanwhile terminal is also needed at other
Network related network operation such as wideband code division multiple access (WCDMA)/GSM/ CDMAs (CDMA) registers letter accordingly
Breath works in LTE network so terminal is practical, but also has log-on message in other networks.
Step 102：It detects whether to receive the access request that the terminal is sent；
Here, the access request be the terminal after the first LTE cells switch to the GSM cell, it is described
The signal strength of 2nd LTE cells is higher than the signal strength of the GSM cell, and the duration of the determining timer T320 is more than
It is sent during the first duration；A length of duration for forcing resident GSM network when described first.
That is, the terminal is after the first LTE cells switch to the GSM cell, when detecting described
When the signal strength of two LTE cells is higher than the signal strength of the GSM cell, and determine the timer T320 when it is long-range super
Pressure is crossed when residing in the duration of GSM network, selects the second community, and send the access request.
Step 103：Determine whether the terminal can be successfully accessed network based on testing result.
Specifically, when receiving the access request that the terminal is sent in preset duration, determine that the terminal can
Network is successfully accessed, so as to further illustrate prioritization scheme success.Network side is the terminal distribution RRC resources at this time, with
RRC establishment of connections are completed, the tracing section updating request that terminal described in receipt of subsequent is sent；Tracing section updating process is completed, and
DRB is re-established for the terminal.
Certainly, when not receiving the access request that the terminal is sent in preset duration, determine that the terminal cannot
Network is enough successfully accessed, so as to illustrate that prioritization scheme fails.
Wherein, it during tracing section updating, is mainly determined by MME according to the current location of the terminal for the terminal
New tracking area list, and it is sent to the terminal.
During practical application, the preset duration can be set as needed.In addition, the preset duration can be by setting
The mode for putting timer is realized；Specifically, when the signal strength of the 2nd LTE cells is strong higher than the signal of the GSM cell
Timer after degree is set, detects whether to receive that the terminal sends detects whether to receive institute before the timer expiry
State the access request of terminal transmission.Wherein, the purpose for setting timer is to avoid the overlong time of detection.
During practical application, in order to verify the validity of prioritization scheme, it can also detect due to various reasons so that the end
End returns to the behavior of LTE network from GSM network again, further to verify the validity of prioritization scheme and reasonability.
Based on this, in one embodiment, the method can also include：
Obtain the second duration；The signal strength that second duration characterizes the 2nd LTE cells is higher than the GSM cell
Signal strength at the time of to the terminal send the access request at the time of between duration；
Obtain third duration；The third duration characterizes the terminal and is received again by the redirection message from described first
After LTE cells switch to the GSM cell again, the signal strength of the 2nd LTE cells is higher than the signal of the GSM cell
Duration between at the time of sending the access request again to the terminal at the time of intensity；
According to second duration and third duration, determine whether the terminal can successfully return to LTE network.
Wherein, the third duration can be understood as the terminal again from GSM return LTE network spent by when
It is long.
In one embodiment, when the third duration is less than the second duration, determine that the terminal can successfully return to LTE
Network further illustrates prioritization scheme success.
When the third duration is greater than or equal to the second duration, determine that the terminal can not successfully return to LTE network,
Illustrate that prioritization scheme fails at this time.

The present invention is described in further detail again with reference to an Application Example.
In this application embodiment, a network environment is constructed by emulation platform, including：2 TDD-LTE (LTE
Cell 0 and LTE Cell 1), 1 GSM cell；It is adjacent that GSM is configured wherein in the SIB7 of LTE Cell 0 and LTE Cell 1
LTE adjacent areas cell information is configured in area's information in GSM SI.Fig. 2A is the schematic diagram that SIB7 is shown by computer display,
Fig. 2 B are the schematic diagram that SI is shown by computer display.
Here, LTE Cell 0, LTE Cell 1, GSM cell are each configured to identical PLMN, identical tracking area coding
(TAC) code.LTE Cell 1 are configured as different frequencies, different Physical Cell Identifier (PCI) address.
Wherein, PLMN refers to：By government or operator that it is ratified, land mobile business purpose is provided for the public
And the network established and managed.During practical application, PLMN is generally set by operator.PLMN by mobile national number (MCC,
Mobile Contrary Dode) and mobile network No. (MNC, Mobile Net Code) composition, wherein, MCC uniquely represents mobile
The belonging country of user, Chinese MCC are 460；MNC uniquely represents that the network in the country, such as China Mobile GSM net are
00, China Unicom GSM net are 01.
Tracking area is that LTE/ System Architecture Evolutions (SAE, System Architecture Evolution) system is terminal

The abnormal scene of this application embodiment is：In UE from LTE network to general packet radio service technology (GPRS) net
In the handoff procedure of network, the redirection message that network side issues carries the option of mistake, and in such a scenario, detection UE exists
Whether GSM cell can not return to LTE after being resident, so that the validity and reasonability of the affected prioritization scheme of data service.
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, as shown in figure 3, including the following steps：
Step 301：UE bootings are triggered to start on register flow path to LTE cell 0；
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 connect 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, in attaching process, the foundation of default EPS bearing (defaultEPSBearer) is completed.
Step 303：After UE completes initialization, data service is initiated；
Step 304：Emulation platform puts (RRCConnectionReconfiguration) to UE initiations RRC connection reconfigurations and disappears
Breath, configuring adjacent cell GSM cell measurement report；
Step 305：Emulation platform reduces current LTE cell (i.e. LTE Cell 0) signal strength, improves the letter of GSM cell
Number intensity so that UE triggerings test report is reported to LTE cells (i.e. LTE Cell 0)；
Step 306：Network sends RRC Connection Releases (RRCConnectionRelease) message, that is, redirects message, inner
Face carries redirection information；
Here, the redirection information includes the frequency point ARFCN of target GSM cell and additional option timer
The value (duration) of the duration of T320, wherein T320 forces resident time-consuming (such as more than 120 seconds) far more than normal GSM network,
Fig. 4 is the schematic diagram of the value of T320 shown by computer display, and in Fig. 4, the value of T320 is 180 minutes.
Step 307：Emulation platform detects the behavior of UE：Within the duration of Timer 1, if UE can be initiated to GSM
The RR connection requests of cell, and then initiate Routing Area Update (RAU) flow and subsequent caller (MO) packet data protocol
(PDP, Packet Data Protocol) data service activation process, to carry out data service；
Step 308：Emulation platform improves the signal strength of LTE Cell 1, makes it higher than gravity treatment trigger gate limit value；
Step 309：Emulation platform monitors the behavior of UE, if UE after 2 time-out of Timer, before 3 time-out of Timer, is sent out
RRCConnectionRequest message is played to LTE cell 1, network distribution RRC resources, to establish RRC connections；
Here, the reason of RRCConnectionRequest message carries value is MO signaling, represents actively to initiate
The signaling of calling.
Wherein, in this process, emulation platform record is sent out from 1 signal intensity time points (moment) of LTE cell to UE
Spent duration between the time point (moment) of RRCConnectionRequest message is played, and is denoted as delta_1, is used
Timer2 represents the duration of Timer 2, and the duration of Timer 3 is represented with timer3, then has delta_1<(timer3–
timer2).Delta_1 is properly termed as returning to the duration spent by LTE network from GSM network.
Here, if step 309 runs succeeded, illustrate prioritization scheme success, if UE remains in GSM cell,
RRCConnectionRequest message is initiated to LTE cell 1, then illustrates that prioritization scheme fails.
Step 310：Emulation platform monitors the behavior of UE：The subsequent initiating updating of tracking area requests of UE
(TrackingAreaUpdate Request) message, network, which receives this, asks and completes tracing section updating (TAU) flow, again
Establish DRB carryings；
Step 311：A new UE of record returns to the duration spent by LTE network from GSM network, is denoted as delta_2；
Here, by performing step 304~309 again, to obtain delta_2, mode and the acquisition of delta_2 are obtained
The mode of delta_1 is identical.
Step 312：If delta_2<Delta_1, it was demonstrated that prioritization scheme success, conversely, illustrating that prioritization scheme fails.
