Background
The Circuit Switched Fallback (CSFB) is used as a LTE network voice service bearing solution, and is applicable to a TD-LTE and 2G/3G wireless network overlapping coverage scene, a typical flow includes that a terminal initiates a call or receives a page at an LTE side, the LTE network issues GSM frequency points through a redirection command (RRC Connection Release), and the terminal reads the GSM frequency points in sequence, finds a proper GSM cell and performs a CS service.
The existing addition scheme of the GSM fallback frequency point of the LTE cell mainly depends on GSI (Geographic Information System) related planning software to plan the GSM frequency point based on distance, and then the GSM fallback frequency point is added one by one without priority.
There is also a GSM frequency point configuration scheme based on Measurement Report (MR). For example, a method for optimizing CSFB frequency point configuration based on measurement report data is disclosed in a chinese patent application having an application number of "201510461451. X". The method comprises the following steps: extracting GSM RSSI and RSRP data in a measurement report periodically reported by an acquisition terminal; combining GSM RSSI data acquired by each sector with the average RSRP of the LTE service cell, carrying out linear coefficient weighted average processing on the MR sampling point ratio, and calculating the linear weighted score of each frequency point coefficient; and optimally configuring the fallback frequency points of the CSFB according to the sequence of the weighted scores calculated by the BCCH from large to small.
The existing circuit switched fallback frequency point adding schemes have certain limitations and are respectively embodied as follows:
although most of suitable adjacent cells can be added by the GIS planning method, the GSM frequency points are not added one by one according to the priority level in consideration of the complexity of a wireless network, the GSM frequency point with the strongest signal can be missed, and the optimal cell cannot be guided back.
The GSM fallback frequency point constructed based on the MR data can avoid the problem that the strongest GSM frequency point is not configured, but the method based on the MR data depends on the integrity and accuracy of MR data acquisition, the data reported by different terminals have large difference, and the problem of power consumption of the terminals can be caused by the need of periodically reporting the GSM frequency point measurement information.

The embodiment of the invention also calculates the quality weight of each switching frequency point corresponding to the co-station GSM cell, takes the switching weight and the quality weight as the index of the frequency point weight, and finally calculates the comprehensive weight value corresponding to the switching frequency points of all the co-station GSM cells.
Each switching frequency point corresponding to the LTE cell, namely a target LTE cell to which the LTE cell is switched in the history switching process is selected, a co-station GSM cell corresponding to each target LTE cell is selected as an adding frequency point, so that the frequency points can be added more completely, the specific mode is that the switching weight values of the switching frequency points corresponding to the LTE cell are sorted from large to small, and the frequency points which can be added into the frequency point configuration table are selected by calculating the cumulative ratio of the switching weight values.

and calculating the product of the switching weight and the quality weight of each switching frequency point corresponding to the GSM cell, wherein the quality weight is the ratio of the uplink quality in a specified interval multiplied by the ratio of the downlink quality in the specified interval.
Since the weight of the switching times of each target GSM cell acquired in S11 is only reflected in the switching amount of the target cell to which each switching frequency point is switched, if the switching is performed only according to the magnitude order of the switching amount of the frequency points, it may be that the switching to the high-quality GSM cell cannot be performed because the ordering of some frequency points with better quality is relatively back. Therefore, the invention calculates the comprehensive weight of the quality and the switching quantity, and can ensure that the high-quality frequency point corresponds to a higher weight value.

In the embodiment of the present invention, S14 specifically includes the following steps:
adding a class B frequency point in the frequency point configuration table according to the weight of each switching frequency point corresponding to the GSM cell comprises:
adding a switching frequency point corresponding to the GSM cell with the weight value larger than a specified threshold value as a B-type frequency point to the back of the A-type frequency point in the frequency point configuration table according to the priority sequence of the weight from large to small;

and adding the falling frequency points with the falling request times larger than a specified threshold value as D-type frequency points to the back of the C-type frequency points in the frequency point configuration table according to the priority sequence of the times from large to small according to the existing circuit switched falling frequency point information of the LTE cell.
The frequency point configuration table provided by the embodiment of the invention sequentially adds the GSM fallback frequency points according to the priority order, and configures the LTE network according to the frequency point configuration table, so that the terminal can be ensured to preferentially fallback to the optimal GSM frequency point.
In this embodiment of the present invention, after adding the class B frequency point in the frequency point configuration table in S14, the method further includes:
and if the frequency point information of different sectors under the GSM cell site which is co-sited with the current LTE cell is not in the B-type frequency point, adding the frequency points of different sectors under the GSM cell site as supplementary frequency points to the back of the B-type frequency point in the frequency point configuration table.
After adding the frequency points of the type A and the type B, checking whether the frequency points of different sectors under the GSM cell site which is co-located with the current LTE cell are in the frequency points of the type B, if the frequency points of the type B exist, adding the frequency points of different sectors under the GSM cell site to the back of the frequency points of the type B in a frequency point configuration table and to the front of the frequency points of the type C according to the sequence in the frequency points of the type B. Therefore, the adding integrity is ensured, and the frequency point information which belongs to the same base station with the co-sited GSM but is positioned in different directions is prevented from being leaked.
The circuit switched fallback frequency point configuration method provided by the invention is explained in detail by using specific examples.

TABLE 3
The class-a data includes basic data (including station name, different sectors under the same base station, longitude and latitude and azimuth) of the LTE cell and the co-sited GSM cell, and specifically, the GSM/LTE co-sited correspondence relationship is sorted based on the following principle:
1) the station names are the same
2) The distance between stations is less than 50 m
3) Cell azimuth difference absolute value cell 30 degrees
