Step 103: network side is optimized processing according to the described drive test measurement result and the described corresponding relation of drive test terminal to report.
In general, the drive test terminal when each surveying record, comprises the measurement event type under the corresponding trigger condition, the measurement result and the positional information of radio signal quality among the drive test measurement result in the drive test measurement process.Among the present invention, writing down and/or reporting employing location index alternative site information among the drive test measurement result, if a plurality of surveying records have identical positional information, can number represent with same location index, and put the corresponding relation of call number and positional information in the last designate bits of giving the correct time.Network side is according to the corresponding relation of the location index in each surveying record number and location index number and positional information, just can know the measurement content on actual position information in each surveying record of drive test terminal.Report thereby optimized measurement result, saved empty overhead.
In the measurement result in the corresponding relation of position call number and positional information, unique corresponding location index of positional information number.And then give the correct time on the measurement result, can there be the surveying record of multiple measurement event type to have identical location index number, also can there be surveying record with a kind of measurement event type that a plurality of different location indexs number are arranged.Below provide four concrete application examples.
Application example one: a kind of drive test measurement event type and a location index are number related
As shown in Figure 2, the drive test process may further comprise the steps:
Step 201: the drive test terminal is carried out RRC at Serving cell and is connected when setting up, network side issues the drive test that postpones to report by special-purpose drive test configuration messages (as: MDTMeasConfiguration) and disposes (the measurement configuration of Logged MDT) information, as shown in Figure 1, the drive test configuration information has comprised measuring amount (as: frequency, sub-district etc.), record and trigger event, positional information, configuration effective time, measured zone etc.Can also issue the position thresholding and give the drive test terminal.
Step 202: the drive test terminal is measured configuration and is come into effect after the measurement configuration that receives drive test, disposes this moment to begin effective time to start, and after the drive test terminal enters the IDLE attitude, has satisfied the measurement event condition of drive test, just carries out measurement of correlation and recorded and stored.For the zone that is in the Serving cell signal stabilization, drive test terminal general measure periodic pilot signal, when periodic measurement timer T triggers, the drive test terminal is measured wireless signal information, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side, give 1 one location indexs of current this positional information number (as: Location 1).When periodic measurement timer T triggered once more, the drive test terminal was measured current location information, found identically with positional information 1 before, then need not write down this positional information, only with Location 1 sign this time the positional information of measurement get final product.By that analogy, after this when the drive test terminal when measurement event triggers, record is wireless signal the time, measuring position information, if identical with Location 1 corresponding position information 1, just directly usefulness Location 1 this location index number gets final product, record position information again, as shown in Figure 3.
Step 203: when the drive test terminal enters connected state once more, in RRCConnectionComplete, there is the drive test measurement record to report by ' LogAvailable ' indication informing network side, network side is after obtaining this indication notice, report if desired, by UEInformationRequest message request drive test terminal to report drive test measurement result, the drive test terminal is by UEInformationResponse information reporting drive test measurement result.In the drive test measurement result, each surveying record also has a positional information call number Location 1 except radio signal quality, temporal information etc.Also have Location 1 corresponding position information at last, one reports network side, as shown in Figure 3.
After network side receives the drive test measurement result of drive test terminal, actual position information according to positional information call number Location1 and call number Location 1 correspondence, just know the pairing positional information of each surveying record, thereby come problem area is optimized processing.
Application example two: multiple drive test measurement event type and a location index are number related
As shown in Figure 4, this drive test process may further comprise the steps:
Step 401: the drive test terminal is carried out RRC at Serving cell and is connected when setting up, network side issues drive test measurement configuration (the measurement configuration of the Immediate MDT) information that reports immediately by existing RRC reprovision configuration messages (RRCConnectionReconfiguration), as shown in Figure 4, measure deploy content and comprised measuring amount (as: frequency, sub-district etc.), record and trigger event, positional information, configuration effective time and measured zone etc.
Step 402: the drive test terminal is after the measurement configuration that receives drive test, measuring configuration comes into effect, dispose this moment and begin effective time to start, satisfy condition (as: the periodic pilot measurement of the measurement event of drive test, the Serving cell signal is less than certain threshold value, the paging channel failure, broadcast channel failure etc.) time, just carry out measurement of correlation and recorded and stored.When periodic measurement timer T triggers, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side, give 1 one call numbers of current this positional information (as: Location 1).When periodic measurement timer T triggers once more, the drive test terminal is measured wireless signal information, and measures current location information, finds identical with before positional information 1, then need not write down this positional information, only the positional information of this time measuring with Location 1 sign gets final product.When the drive test terminal detects the Serving cell signal less than certain threshold value, record wireless messages quality information, and measuring position information are found identical with before positional information 1, then need not write down this positional information, only the positional information of this time measuring with Location 1 sign gets final product.By that analogy, after this (paging channel is failed when the drive test terminal triggers in measurement event, the broadcast channel failure) time, in the time of the record wireless signal, if measuring position information identical with Location 1 corresponding position information 1, just directly gets final product with Location 1 this call number, record position information again, as shown in Figure 5.
Step 403: the drive test terminal is triggered in the drive test measurement incident, after having measured measurement of correlation, just directly surveying record being reported network side by measurement report (Measurement Report), in this surveying record message, except the wireless environment signal message, also has the positional information call number;
Step 404: the drive test terminal wait until that network side is asked reporting position (as LocationRequest) once more or after having reported measurement result etc. a period of time, again by one independently positional information reporting message (as: LocationReport) report and surveying record corresponding position information before.In this location information report, contain the corresponding relation of actual position information and positional information call number.
After network side receives the drive test measurement result and location information report of drive test terminal, actual position information according to positional information call number Location 1 and call number Location 1 correspondence, just know the pairing positional information of each surveying record, thereby come problem area is optimized processing.
Application example three: a kind of drive test measurement event type and a plurality of location indexs are number related
The flow process of this application example is the surveying record process of drive test terminal with the difference of application example one as shown in Figure 2:
After the drive test terminal enters the IDLE attitude, satisfy the condition (as: periodic pilot is measured, and the Serving cell signal is less than certain threshold value, and paging channel is failed, broadcast channel failure etc.) of the measurement event of drive test, just carried out measurement of correlation and recorded and stored.For the zone that is in the Serving cell signal stabilization, drive test terminal general measure periodic pilot signal, when periodic measurement timer T triggers, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side, give call number of current this positional information (as: Location 1).When periodic measurement timer T triggered once more, the drive test terminal was measured current location information, found identically with positional information before, then need not write down this positional information, only with Location 1 sign this time the positional information of measurement get final product.If different, then write down this positional information, and identify current this positional information with new call number (as Location 2).By that analogy, after this when the drive test terminal when measurement event triggers, in the time of the record wireless signal, if measuring position information identical with Location 1 corresponding position information 1, just directly gets final product with this call number of Location1, record position information again, if identical, just directly get final product, again record position information with Location 2 these call numbers with Location 2 corresponding position information 2.If positional information before 1 is all different with positional information 2, then writes down this positional information, and indicate this positional information with new sign.Accurately measuring position information or network side are given the situation of drive test terminal configuration measuring position information for the drive test terminal, the drive test terminal is when the reporting measurement record report, can location information adopt sky or index of reference number zero (Location 0) mark, as shown in Figure 6.
Application example four: multiple drive test measurement event type and a plurality of location indexs are number related
The flow process of this application example is the surveying record process of drive test terminal with the difference of application example one as shown in Figure 2:
After the drive test terminal enters the IDLE attitude, satisfy the condition (as: periodic pilot is measured, and the Serving cell signal is less than certain threshold value, and paging channel is failed, broadcast channel failure etc.) of the measurement event of drive test, just carried out measurement of correlation and recorded and stored.When periodic measurement timer T triggers, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side; When Serving cell signal during, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side less than certain threshold value; When paging channel is failed, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side, or the like.
The drive test terminal is when reporting drive test measurement as a result, and positional information is identical in the surveying record, then uses same call number record, and positional information is extracted the corresponding relation of independent stored position information and call number.As the position in the periodic pilot surveying record 1 is positional information 1, and Serving cell is a positional information 2 less than the position in the surveying record 1 of certain threshold value, and the position in the periodic pilot surveying record 2 is a positional information 3, or the like.Positional information 1 corresponding Location1, positional information 2 corresponding Location2, positional information 3 corresponding Location3, or the like.As shown in Figure 7.
Application example five: drive test measurement report and positional information independently report
As shown in Figure 8, the process that reports of drive test comprises:
Step 801: the drive test terminal is carried out RRC at Serving cell and is connected when setting up, the drive test measurement configuration that network side postpones to report by special-purpose drive test configuration messages (as: MDTMeasConfiguration) (the measurement configuration of Logged MDT), measure deploy content and comprised measuring amount (as: frequency, sub-district etc.), record and trigger event, positional information disposes effective time, measured zone etc.Can also issue the position thresholding and give the drive test terminal.
Step 802: the drive test terminal is after the measurement configuration that receives drive test, measuring configuration comes into effect, dispose this moment and begin effective time to start, after the drive test terminal enters the IDLE attitude, (as: periodic pilot is measured, and the Serving cell signal is less than certain threshold value, the paging channel failure to have satisfied the condition of the measurement event of drive test, broadcast channel failure etc.), just carry out measurement of correlation and recorded and stored.When periodic measurement timer T triggers, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side; When Serving cell signal during, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side less than certain threshold value; When paging channel is failed, the radio signal quality of drive test terminal record Serving cell, and measure the drive test terminal current position information line item of going forward side by side, or the like.
Step 803: when the drive test terminal enters connected state once more, in RRCConnectionComplete, there is the drive test measurement record to report by ' LogAvailable ' indication informing network side, network side is after obtaining this indication notice, report if desired, by UEInformationRequest message request drive test terminal to report drive test measurement result, the drive test terminal is by UEInformationResponse information reporting surveying record.The drive test measurement record has comprised radio signal quality information, temporal information, positional information call number.Positional information is identical, then uses same call number record.
Step 804: the drive test terminal is after reporting the drive test measurement result, network side is asked drive test terminal to report positional information or a period of time such as after having reported measurement result again, the drive test terminal is stored the corresponding relation of actual position information and positional information call number in location information report.As the position in the periodic pilot surveying record 1 is positional information 1, and Serving cell is a positional information 2 less than the position in the surveying record 1 of certain threshold value, and the position in the periodic pilot surveying record 2 is a positional information 3, or the like.Positional information 1 corresponding Location1, positional information 2 corresponding Location2, positional information 3 corresponding Location3, or the like.Then the drive test terminal is when reporting the drive test location information report, and the inside has comprised the corresponding relation of location index number and actual positional information, as shown in Figure 9.
After network side receives the drive test measurement result and location information report of drive test terminal,, just know the pairing positional information of each surveying record, thereby come problem area is optimized processing according to the corresponding relation of positional information and call number.
In the above application example, network side can also utilize the position thresholding of issuing for the drive test terminal when measuring configuration.When positional information changes within this thresholding, just think that positional information is identical, otherwise change in location surpasses this thresholding, record position information again just number marks with different location indexs.
For realizing above method, the present invention also provides a kind of driver test system, and as shown in figure 10, this system comprises drive test terminal and network optimization unit, wherein:
