Fig. 1 is the flow chart of method for shunting mobile communication telephone traffic the first embodiment of the present invention, as shown in Figure 1, the method for shunting mobile communication telephone traffic that the embodiment of the present invention provides is carried out by shunting mobile communication telephone traffic device, this shunting mobile communication telephone traffic device is arranged on the server of network side, with operation maintenance center's (Operations & Maintenance Center is called for short OMC-R) communication connection.Also can be integrated on OMC-R equipment, database direct and OMC-R carries out data interaction.
Shunting mobile communication telephone traffic device can adopt the form of software and/or hardware to realize, and the method comprises:
Step S100, obtains TDS measurement report and the drive test data of presetting terminal to report under handoff threshold value, and described TDS measurement report comprises TDS level and GSM level, and described default handoff threshold value comprises default TDS level threshold value and default GSM level threshold value;
Terminal, according to predeterminated frequency, reports a MR to base station at set intervals, and base station is sent to OMC-R equipment by MR by RNC by lub interface, the MR that the database in OMC-R equipment reports for storage terminal at every turn.Shunting mobile communication telephone traffic device is connected with OMC-R devices communicating, obtains the MR under default handoff threshold value, and in the time that terminal is positioned at TDS community, the MR reporting is TDS measurement report, and in the time that terminal is positioned at GSM adjacent area, the MR reporting is GSM measurement report.Wherein default handoff threshold value is default TDS level threshold value and the default GSM level threshold value that operator formulates, when the community level of the residing TDS of terminal community is lower than default TDS level threshold value, the community level of the GSM adjacent area of Er Gai TDS community during higher than default GSM level threshold value, switches to this terminal in GSM adjacent area from current TDS community.TDS measurement report comprises the community level of current TDS cell ID, terminal iidentification and adjacent GSM adjacent area.
Drive test data is for by existing road measuring device, by analog subscriber call in TDS community, the TDS level that test obtains and the corresponding relation of Block Error Rate, at TDS level be for example-65 community A in the test Block Error Rate that obtains data communication be 0.02%.
Step S102, according to described TDS measurement report, band model is switched to setting up in the community of Mei Dui TDS community and GSM adjacent area composition, described switching band model comprises the corresponding relation of described community centering TDS level, GSM level and TDS measurement report number, and the corresponding relation of TDS level, GSM level and GSM measurement report number;
Obtain after the TDS measurement report that in TDS community, terminal reports at every turn, according to the multiple GSM adjacent area showing in TDS measurement report, divide GaiTDS community respectively with composition community pair, each GSM adjacent area, Dui Meidui community to set up switch band model.TDS measurement report thes contents are as follows:
For speech business, the MR number periodically reporting can reflect real telephone traffic, and for example TD community A has reported 100 MR, has comprised the level of community A and GSM adjacent area B in each MR, by statistics, can obtain:
The community pair of DuiTDS community A and GSM adjacent area B composition, sets up and switches band model, the switching band model schematic diagram that Fig. 2 Wei Yige community is right, and as shown in Figure 2, the X-axis of switching band model is TDS level, and Y-axis is GSM level, and Z axis is MR number.This switching band model is for identifying lower corresponding MR number producing of TDS level and different GSM level.
The TDS measurement report of collecting according to OMC-R equipment is known, the corresponding relation of each TDS level, GSM level and TDS measurement report number.And because TDS level and GSM level are constantly changing, therefore when TDS level is low to moderate default TDS level threshold value threshold value, and GSM level is high during to default GSM level threshold value threshold value, terminal under TDS community will be switched in GSM adjacent area, now OMC-R equipment cannot be collected the GSM measurement report number of terminal to report in GSM adjacent area, therefore needs to extrapolate according to the corresponding relation of known TDS level, GSM level and TDS measurement report number the corresponding relation of TDS level, GSM level and GSM measurement report number.
Step S104, sets up user awareness model according to drive test data, and described user awareness model comprises the incidence relation of described TDS level and Block Error Rate;
The threshold value of the following line level of switching of TDS community and GSM adjacent area is as basis for estimation, therefore converse by road measuring device analog subscriber, Block Error Rate under value statistics and this TDS level of extraction TDS level, set up user awareness model, user awareness model is used for identifying the corresponding Block Error Rate of different TDS level.
Fig. 3 is user awareness model schematic diagram, as shown in Figure 3.The relation between the Block Error Rate under value and this TDS level of TDS level of for example adding up is as follows:
Step S106, according to described user awareness model, described switching band model and default Block Error Rate threshold value, adjusts described default handoff threshold value to best default handoff threshold value.
Default Block Error Rate threshold value is the user awareness thresholding that operator arranges TDS community, and when the Block Error Rate of DangTDS community is greater than default Block Error Rate threshold value, the terminal use's perception in GaiTDS community is poor, need to switch in the GSM adjacent area that level value is higher.According to default Block Error Rate threshold value inquiring user sensor model, obtain default TDS level corresponding to Block Error Rate threshold value, further switch band model according to this TDS level inquiry and obtain MR number corresponding under different TDS level, adjust default handoff threshold value to best default handoff threshold value, make under best default handoff threshold value, stay telephone traffic in TDS community maximum.

Fig. 4 is the flow chart of method for shunting mobile communication telephone traffic the second embodiment of the present invention, and as shown in Figure 4, this enforcement is carried out by shunting mobile communication telephone traffic device, specifically comprises:
Step S200, obtains TDS measurement report and the drive test data of presetting terminal to report under handoff threshold value, and described TDS measurement report comprises TDS level and GSM level, and described default handoff threshold value comprises default TDS level threshold value and default GSM level threshold value;
Step S202, according to described TDS measurement report, switches band model to the community of Mei Dui TDS community and GSM adjacent area composition to setting up, calculate every pair of described community to described in the corresponding relation of TDS level, GSM level and described TDS measurement report number;

When GSM level is higher than default GSM level threshold value T1 and TDS level during lower than default TDS level threshold value G1, terminal under TDS community switches to GSM community, P2 and P3 are the point that reports TDS measurement report in terminal TDS community, therefore C3 and C4 are known TDS measurement report number, and the TDS level of P2 is less than default TDS level threshold value, GSM level is higher than default GSM level threshold value, therefore the corresponding terminal of P2 point has been switched to GSM adjacent area, cannot get the GSM measurement report number of this terminal in GSM adjacent area, need to compensate by P3 and P4 the Fitting Calculation, concrete formula is as follows:
C2＝[(T1-T2)*C4+(G2-G1)*C3]/(T1-T2+G2-G1)
Due to C4 and C3 value all known, therefore just can calculate the TDS measurement report number C3 of P3, P4 and C4 and calculate the GSM measurement report number C2 of P2.
For example, in the switching band model of A HeGSM community, TDS community B, TDS level be-93, GSM level-75 correspondence MR number statistics less than, i.e. P2 (93 ,-75, C2), can carry out the Fitting Calculation by above-mentioned algorithm and obtain.
| The TDS level (dBm) of community A | The GSM level (dBm) of GSM adjacent area | MR number |
| -80 | -80 | 16 |
[0063]?
| -90(T1) | -75(G2) | 12(C3) |
| -93(T2) | -75(G2) | C2 |
| -93(T2) | -79(G1) | 4(C4) |
Can obtain P3 (90 ,-75,12) from upper table, P4 (93 ,-79,4), C2=8.
Therefore according to TDS measurement report, can switch band model to setting up to the community of Mei Dui TDS community and GSM adjacent area composition, wherein switch the corresponding relation that band model comprises community centering TDS level, GSM level and TDS measurement report number, and the corresponding relation of TDS level, GSM level and GSM measurement report number.

Step S308, adjusts described default TDS level threshold value according to the described TDS level that described default Block Error Rate threshold value is corresponding, makes the described default TDS level threshold value after adjusting close to TDS level corresponding to described default Block Error Rate threshold value;
Step S310, according to described switching band model, obtains described GSM measurement report number corresponding to multiple described TDS level after adjusting, and obtains the described TDS level corresponding to minimum value of described GSM measurement report number;
Step S312, according to described user awareness model, judge the corresponding TDS level of minimum value of described GSM measurement report number, whether Block Error Rate corresponding in described user awareness model is greater than described default Block Error Rate threshold value, if be less than described default Block Error Rate threshold value, enter step S314;
