Typical CSFB service flows mainly include joint attachment, location update, Mobile Originating (MO) CSFB flow, called (MT) CSFB flow, and detach.
Currently, in a CSFB call implementation procedure, when a Mobile terminal has an incoming call, a Mobile Switching Center (MSC) sends a paging request to a Mobility Management Entity (MME), the MME sends a paging request to the Mobile terminal, the Mobile terminal receives the paging request sent by the MME, the Mobile terminal sends an extended service request to the MME, and the MME sends a Mobile terminal fallback cell indication to an eNB.

The cell ID is used for uniquely identifying a cell, the fallback cell frequency point information is frequency point information corresponding to the cell ID, and the successful fallback times are successful fallback times associated with the cell ID and the fallback cell frequency point information corresponding to the cell ID.

And S25, sending the stored current fallback cell identification and the corresponding fallback cell frequency point information to the base station.
Through the above steps S21-S25, after the mobile terminal completes the joint attach procedure, the mobile terminal performs cell fallback and call establishment 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 invention, under the condition that a circuit domain fallback call is successful, the mobile terminal sends the cell ID and the corresponding fallback cell frequency point information stored in the CSFB call implementation process to the eNB, 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, and indicates the circuit domain fallback processing of the subsequent blind redirection mode according to the sorted all fallback cell frequency point information, thereby reducing the measurement times of the successful fallback cells of the mobile terminal, further reducing the fallback time delay in the CSFB service process, improving the rate of the communication service in the LTE network, and improving the user experience.
The blind redirection fallback method can optimize the blind redirection of the mobile terminal. Illustratively, the mobile terminal is a 4G multi-mode card and selects CSFB technology to realize voice call.

And after the call is finished, the mobile terminal stores the frequency point information of the fallback cell, returns to the LTE network, sends the stored cell ID information and the corresponding frequency point information of the fallback cell to the eNB, adds one to the successful fallback times associated with the cell ID information and the corresponding frequency point information of the fallback cell in the association table by the eNB, 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 issues the incoming call to the user according to the sorted frequency point information of all the fallback cells.
