CSFB flows are carried out, so as to verify the validity and reasonability of UE sides 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 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 configured 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

Step 201：UE is redirected to 0 cells of GSM, completes location updating (LU, Location Updating) and GPRS
Mobile management (GMM, GPRS Mobility Management) Routing Area Update (RAU, Route Area Update) flow
Afterwards, LTE cells are returned to.
Step 202：Network side triggers MT CSFB flows, and network side sends paging message (Paging) and gives 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
Cease 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 notify calling connecing
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 that 1 cells of GSM are carried in order.As shown in figure 4, base station, which issues R8, redirects order
(rrcConnectionRelease_R8 (0)) gives UE, which carries the frequency point information of 1 cells of GSM, due to 1 cells of GSM
Network congestion, this exception scene cause terminal when accessing GSM 1 without response.
Step 203：UE initiates the access of 1 cells of GSM according to the frequency point information (frequency point information of 1 cells of GSM) specified, by
Response is not received in the access request that 1 subzone network congestions of GSM cause to initiate.Wherein, as a kind of embodiment, UE hairs
The access request for playing default quantity (such as 3 times) does not receive response still.
Step 204：UE obtains the frequency point information of 0 cells of GSM, the frequency point information based on 0 cells of GSM according to record
0 cells of GSM are accessed, and ask Internet resources to establish voice communication.If not accessing 0 cells of GSM in non-preset time period, say
Bright CSFB falls failure after rise.Wherein, access cause parameter is carried during request access 0 cells of GSM, which corresponds to
The terminal is initiated when CSFB flows access the second GSM cell without response.
Step 205：Whether detection UE obtains the Internet resources of 0 cells of GSM and establishes voice communication, if it is, performing
Step 206, otherwise, illustrate that CSFB falls failure after rise, that is to say, that default CSFB prioritization schemes failure.
Step 206：Detection UE whether voice communication foundation after keep voice communication, if it is, explanation CSFB fall after rise
Success, otherwise, illustrates that CSFB falls failure after rise, that is to say, that default CSFB prioritization schemes failure.
