Personnel cost is substantially reduced, meanwhile, it is capable to eliminate under the described scene of the embodiment of the present invention other factors to testing result
Influence.
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：Time division duplex (TDD)-LTE
Cell, TDSCDMA cells, GSM cell；Wherein, two adjacent area cell informations are configured in LTE SIB, i.e. GSM 0 and GSM 1 believe
Breath configures LTE adjacent areas cell information in GSM SI.
The abnormal scene of this application embodiment is：0 cells of GSM that network side is specified are without service, the weak letter of adjacent area GSM1 cells
Number, so as to come verify UE sides CSFB failure after prioritization scheme validity and reasonability.
Endpoint detection methods of this application embodiment based on CSFB, as shown in Fig. 2, comprising the following steps：
Step 200：UE is registered in LTE cells, carries out attachment flow；
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 CSFB in the instruction terminal.Fig. 3 is showing for the simulation code of the embodiment of the present invention
It is intended to one, wherein：IMS voice over PS (V)=Not supported (0), represent the indication information.It is in addition, described
Indication information also indicates the terminal using the default prioritization scheme that LTE network is returned by CSFB.
Step 201：Network side triggers MT CSFB flows, and network side sends paging message (Paging) to UE, starts CSFB
Flow；
Here, it is necessary to which MO initiates the calling for MT first during practical application, then, MT just receives network side and issues
Paging message.
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.Redirect the frequency point information for being carried in order and specifying GSM cell (being assumed to be GSM 0).As shown in figure 4, base station issues R8
Order (rrcConnectionRelease_R8 (0)) is redirected to UE, which carries the frequency point of target GSM cell, that is, GSM 0
Information, however GSM 0 is without service, and 1 cell signals of GSM do not meet access requirement, i.e. signal strength is being accessed under thresholding,
This exception scene causes terminal to perform CSFB failures.
Step 202：0 cell signals of GSM are closed by emulation platform, to simulate designated area without service；It turns down simultaneously
The signal strength of 1 cells of GSM to access thresholding under, it is unavailable to simulate adjacent cell, so as to simulate CSFB flows fall after rise failure
Scene, the CSFB failures of UE execution at this time；
Step 203：Detect whether UE initiates in specified timer duration in LTE network side
RRCConnectionRequest message if it is, performing step 204, otherwise, illustrates that LTE network returns to failure, that is,
It says, default prioritization scheme failure；
Step 204：After UE completes RRC connections foundation, whether detection UE sends to core net
TrackingAreaUpdateRequest message if so, completing flow, illustrates that LTE network returns successfully, default optimization
Scheme success；Otherwise, illustrate that LTE network returns to failure, default prioritization scheme failure.
Wherein, the prioritization scheme of LTE network is rapidly returned to according to UE after default CSFB failures, when UE performs CSFB failures
Afterwards, UE should return to LTE network in time.
Here, UE does not initiate RRCConnectionRequest message before timer expiry, and UE may continue at this time
Scan the frequency point of GSM cell, it is also possible to generate false alarm information (OOS).
