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 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 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 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
In reserve two physical channels to CCCH, this exception scene causes terminal when performing CSFB flows and accessing to 1 cells of GSM
It can not initiate CSFB flows.
Step 202：UE can not initiate CSFB according to the frequency point information specified, so performing a scan rapidly, obtain GSM
The frequency point information of 0 cell, frequency point information access 0 cells of GSM based on 0 cells of GSM in preheating setting time section, and please
