Through the steps S21-S25, after completing the joint attachment procedure, the mobile terminal performs cell fallback and establishes a call according to the preconfigured fallback cell information sent by the base station, so as to implement the CSFB call implementation procedure.
According to the blind redirection fallback method provided by the embodiment of the application, the mobile terminal sends the cell ID and the corresponding fallback cell frequency point information stored in the CSFB call realization flow to the eNB under the condition that the circuit domain fallback call is successful, so that the eNB updates the successful fallback times associated with the cell ID information and the corresponding fallback cell frequency point information in the pre-established association table, sorts all fallback cell frequency points under the cell ID information according to the successful fallback times, indicates the circuit domain fallback processing of the follow-up blind redirection mode according to the sorted all fallback cell frequency point information, reduces the measurement times of the successful fallback cells of the mobile terminal, further reduces the fallback time delay in the CSFB service flow, improves the communication service rate in the LTE network, and improves the user experience.
The blind redirection fallback method provided by the embodiment of the application can optimize the blind redirection of the mobile terminal. Illustratively, the mobile terminal is a 4G multimode card and selects CSFB technology to implement the voice call.

After the call is ended, the mobile terminal stores the information of the frequency point of the fallback cell, returns to the LTE network, sends the stored cell ID information and the corresponding information of the frequency point of the fallback cell to the eNB, and the eNB adds one to the successful fallback times associated with the cell ID information and the corresponding information of the frequency point of the fallback cell in the association table, and sorts all the frequency points of the fallback cell under the cell ID information according to the successful fallback times. And when the user under the cell ID has an incoming call, the eNB sends the information of all the fallback cell frequency points after sequencing to the user.
Fig. 3 shows a flow diagram of a blind redirect fallback method according to an exemplary embodiment of the application. As shown in fig. 3, the method may include the following steps.
S301, the eNB establishes an association table.
In this step, the association table is used to store cell ID information, fallback cell frequency point information, and the number of successful fallback times.
S302, the mobile terminal, for example, the 4G multimode card, sends an Attach Request (Attach Request) message to the MME.
In this step, after The mobile terminal is powered on, the joint attachment flow of The fourth generation mobile information system (The 4th Generation Mobile Communication Technology, 4G) multimode card is started. Wherein, the attachment request carries parameters: attachment Type Attach Type. The attach type indicates that this is a joint evolved packet system (Evolved Packet System, EPS)/international mobile subscriber identity (International Mobile Subscriber Identification Number, IMSI) attach procedure and the parameters indicate that the mobile terminal is circuit switched Fallback (Circuit Switched Fallback, CS Fallback) capable.
S303, the MME sends a LOCATION UPDATE REQUEST message (SGsAP-LOCATION-UPDATE-REQUEST) to the corresponding visitor LOCATION register (Visited Location Registor, VLR).
In this step, the location update request message includes parameters such as a location area identifier (Location Area Identify, new LAI), IMSI of the 4G multimode card, MME identifier (MME Name), and location update type (Location Update Type).
S304, the VLR stores the MME information and creates SGs association with the 4G multimode card under the MME.
In this step, SGs is the interface between MSC/VLR and MME through which the joint attach function can be implemented.
S305, the VLR initiates a 4G multimode card position updating process to a home location register (Home Location Register, HLR) according to the user information and the position area information.
S306, the VLR returns confirmation information to the MME.
S307, the MME sends an Attach Accept (Attach Accept) message to the mobile terminal to complete the joint attachment.
S308, when the mobile terminal has an incoming call, the calling MSC sends a call request to the attached MSC of the mobile terminal.
In this step, the attaching MSC becomes the called MSC.
S309, the called MSC sends out a paging request to the MME.
S310, the MME sends a paging request to the mobile terminal.

In the step, if the measurement result is that the current fallback cell is suitable for residence, the mobile terminal falls back to the cell, otherwise, the mobile terminal measures the next fallback cell information in the configured fallback cell information until the cell suitable for residence is determined according to the measurement result.
S315, after the mobile terminal falls back to the cell where the mobile terminal is suitable to reside, the cell identification is judged to be inconsistent with the cell identification when the mobile terminal is combined with the cell identification when the mobile terminal is attached, the mobile terminal performs position updating, and then sends call establishment information to the called MSC to establish a call.
S316, after the call is ended, the mobile terminal stores the information of the frequency point of the fallback cell and returns to the LTE network.
S317, the mobile terminal sends the stored cell ID information and the corresponding fallback cell frequency point information to the eNB.
And S318, the eNB adds one to the successful fallback times associated with the cell ID information and the corresponding fallback cell frequency point information in the associated table, and sequences all the fallback cell frequency points under the cell ID information according to the successful fallback times.
In the step, when the mobile terminal of any user under the cell ID has an incoming call, the eNB sends the information of all the fallback cell frequency points after sequencing to the mobile terminal of the user.
Through the steps S301-S318, the eNB establishes an association table, stores the cell ID information, the fallback cell frequency point information and the successful fallback times, and after the CSFB call is successful, the mobile terminal sends the stored cell ID information and the fallback cell frequency point information to the eNB, and the eNB reorders the successful fallback times together.
