Ask failure) after, initiate attach request etc..
In this way, method provided in an embodiment of the present invention, is being carried out based on instruction terminal using default CSFB prioritization schemes
During the indication information of speech business performs CSFB, detect for the terminal under wideband code division multiple access WCDMA networks
The failure information of the packet switched ps domain access authentication flow of initiation；The failure information of the ps domain access authentication flow is described
What terminal was initiated in the WCDMA networks after the completion of the voice communication based on circuit-switched CS domain is established accesses for ps domain
The failed authentication information of authorizing procedure；In the state of the failure of the ps domain access authentication flow, detect the terminal and exist
Voice call state under WCDMA networks；At least judge whether the CSFB falls success after rise based on the voice call state；Its
In, in the attachment received message that the indication information carrying is sent in the LTE base station to the terminal；The attachment receives to disappear
Breath is that terminal LTE base station after LTE base station transmission Attach Request message is sent；The CSFB processes are the ends
Triggering performs when termination receives the paging message that the LTE base station is sent.It, can using scheme provided in an embodiment of the present invention
During terminal falls back to and detects CSFB after the WCDMA cells that network side specifies under the scene of ps domain access authentication flow failure

During, further improvement and optimization scheme the successful probability of CSFB processes can be improved, to promote the calling of user experience.
In addition, detection is located at voice call state of the terminal under WCDMA networks under emulated network environment, use
The mode of emulation is not required staff to go to scene, and can remove the factor of other influences detection, so, it is possible to substantially reduce
Personnel cost, meanwhile, it is capable to eliminate influence of the other factors to testing result under the described scene of the embodiment of the present invention.
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, it is small including frequency division duplex (FDD)-LTE
Area and WCDMA cells；Wherein, it is adjacent area cell information WCDMA 1 to be configured in LTE SIB, and LTE is configured in WCDMA SIB18
Adjacent area cell information.
The abnormal scene of this application embodiment is：Since terminal does not open 3G data services, CSFB is caused to fall back to specified
WCDMA cells after RAU authorizing procedures fail, terminal still can utilize CS resources to complete CSFB and complete in this case for verification
Into voice communication, so as to verify the validity and reasonability of end side call prioritization scheme.
The detection method of the falling result of this application embodiment CSFB, as shown in Fig. 2, comprising the following steps：
Step 201：In UE registration LTE cells, attachment flow is carried out；
Specifically, after UE MT, UE start, joint evolved packet system (EPS, Evolved Packet is first carried out
System)/international mobile subscriber identity (IMSI, International Mobile Subscriber
Identification Number) attachment flow.
Wherein, include triggering UE in this process and send Attach Request message (Attach Request) to LTE base station,
The attachment received message (Attach Accept) that the LTE base station is sent is received, wherein, the attachment received message, which carries, to be used
The indication information of speech business is carried out using default CSFB prioritization schemes in the instruction terminal.Fig. 3 is the embodiment of the present invention
Simulation code schematic diagram one, wherein：IMS voice over PS (V)=Not supported (0), represent the instruction
Information.
Step 202：Network side triggers MT CSFB flows, and network side sends paging message (Paging) to UE, starts CSFB
Flow；
Specifically, after the mobile services switching centre in network (MSC) receives initial address request (IAM) incoming message,
According to existing SGs associations and mobile management entity (MME, Mobility Management Entity) information, send
SGsAP-PAGING-REQUEST message is to MME, and here, SGsAP-PAGING-REQUEST message carries following information：IMSI、
Temporary Mobile Subscriber Identity (TMSI, Temporary Mobile Subscriber Identity), service identification (Service
Indicator), calling number, location area information.
MME sends paging (Paging) message to base station after receiving message, and the Paging flows eated dishes without rice or wine are initiated in base station.UE is built
Vertical to connect and send Extended Service Request message to MME, MME sends SGsAP-SERVICE-REQUEST and disappears
It ceases to MSC, MSC receives this message, no longer retransmits paging request message to MME.To avoid in call-connection process, caller waits
Overlong time, MSC receive the SGs Service Request message for including Idle state instruction, first calling are notified to connect
During continuous.MME sends Initial UE Context Setup message to base station, here, Initial UE Context
Setup message carries CS Fallback Indicator, CS Fallback Indicator and is used to indicate base station UE because of CSFB
Business needs to fall back to UMTS Terrestrial radio access network (UTRAN, UMTS Terrestrial Radio Access
Network)/GSM EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network).
In attachment flow, UE receives the LTE_RRCConnectionRelease signalings of LTE base station transmission, that is, redirects
Order.It redirects in order and carries the frequency point information of specified WCDMA cells namely the frequency point information of target WCDMA cells.
As shown in figure 4, base station, which issues R8, redirects order (rrcConnectionRelease_R8 (0)) to UE, the order
The frequency point information of target WCDMA cells is carried, in this way, redirecting the frequency point information carried in order access based on R8 convenient for UE
Target WCDMA cells.
Step 203：WCDMA is accessed according to the frequency point information (namely frequency point information of target WCDMA cells) specified in UE
After cell, RRC Request are initiated, network side issues CS call resources, radio access bearer (RAB) setup, voice communication
It establishes and completes；It is simulated at this time by emulation platform：Ps domain access authentication flow fails, and terminal can not obtain ps domain resource, fail
After finishing after the flow of RAU.
At this point, checking UE in this case, whether the voice call state in CS domains is affected；Whether in end of conversation
Afterwards, energy FastReturn successfully returns to LTE network namely whether LTE network can be returned in preset time.
Specifically：
Step 204：Check UE in this case, whether the voice call state in CS domains is not affected, that is, detects UE
In this case, if voice communication can be kept, if so, performing step 205；Otherwise, illustrate that CSFB falls failure after rise,
That is default CSFB prioritization schemes failure；
Step 205：Detect end of conversation after UE whether preset time grow in return LTE network, if so, illustrating CSFB
It falls after rise successfully, otherwise, illustrates that CSFB falls failure after rise.
Step 206：Judge UE after RAU asks PS failed authentications, if to initiate attach request；If so, illustrate that CSFB is returned
Fall unsuccessfully.Otherwise, illustrate that CSFB is fallen after rise successfully.
In practical application, the execution step of step 204 and step 206 can overturn, and the present embodiment is to step 204 and 206
Execution sequence be not limited.
When the UE cannot return to LTE network in preset duration, at this time the UE may be an attempt to WCDMA networks into
