Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright each embodiment is explained in detail.However, it will be understood by those skilled in the art that
In each embodiment of the invention, in order that reader more fully understands the application and to propose many technologies thin
Section.But, even if there is no these ins and outs and many variations based on following embodiment and modification,
The each claim of the application technical scheme required for protection can also be realized.
The first embodiment of the present invention is related to a kind of minimum road measuring method.Its flow process as shown in Fig. 2
It is specific as follows：
Step 201, opens MDT intervalometers.
Step 202, opens positioning timing device.
Specifically, compared with prior art, inventor is additionally arranged positioning timing to present embodiment
Device (referred to as " Ta "), for controlling the unlatching of locating module.The Ta for setting up is opened in MDT intervalometers
Synchronously open when opening, then locating module is opened when the timer expiry, MDT intervalometers
(referred to as " Tmdt ") is opened when certain MDT measurement terminates, substantially all with DRX
The integral multiple of phase is synchronous.In particular, the locating module in present embodiment can be GPS (complete
Ball global position system) locating module.
It should be noted that the timed length of Ta is less than the length of MDT intervalometers in present embodiment,
If the length of Ta has exceeded the length of MDT intervalometers, then be to open all the time equivalent to GPS module
Open.
In addition, the unlatching GPS module and closing GPS module in present embodiment is all for high-rise association
For view module, that is, it is exactly to make GPS module be in continuous operation mode to open GPS module, and high
It is exactly to make GPS module be in battery saving mode that layer closes GPS module.
Mode of operation of GPS module in present embodiment is specifically described at this, on the one hand,
Under IDLE state, physical layer carries out cell measurement always to be carried out with DRX (discontinuous to receive) cycles,
The measurement result of MDT needs can be measured within this cycle, this process continues tens to hundreds of millisecond,
That is, physical layer is inherently waken up at a certain time interval, after completing measurement, keep low again
Power consumption state.On the other hand, if GPS module is not long-time is maintained at continuous operation mode, because
Open until being obtained in that location information needs certain hour from GPS module, in order that MDT enters
Location data can be obtained during row, then just should be before physical layer starts measurement, when certain in advance
Between open GPS module.How long this time need on earth, under different wireless environments and differs,
Easily affected by weather, network wireless environment, surrounding building and indoor and outdoor surroundingses, such as 5 seconds
The latter is obtained with result the shorter time, there may come a time when slow, it may be necessary to more than ten seconds.And
It is generally believed that the change of this capture time length is generally slow.So, in the present embodiment,
Bit timing device can rule of thumb be given by designer and one initial value is set, recycle follow-up dynamic
Set-up procedure so that the duration of Ta more meets actual environment.
Step 203, judges whether positioning timing device is overtime；If so, then execution step 204；If it is not,
Execution step 203 is returned then.
Step 204, opens locating module.
Specifically, step 203 is to control opening for locating module using the mode of intervalometer timing to 204
Open the time.As Ta is less than Tmdt, so the unlatching of locating module will be earlier than during the beginning of MDT
Between.
Step 205, judges whether MDT intervalometers are overtime；If so, then execution step 206；If it is not,
Execution step 202 is returned then.
Step 206, starts MDT.
Specifically, step 205 is unlatching that MDT is controlled using the mode of intervalometer timing to 206
Time.
Step 207, judges whether location data obtains successfully；If so, then execution step 208；If it is not,
Execution step 209 is returned then.
It should be noted that step 207 is to the 209 dynamic adjustment i.e. to Ta, using in each MDT
During beginning, whether location data has been acquired to adjust the time that locating module is opened next time.
Specifically, if it is decided that when MDT starts, location data is acquired, then postpone positioning mould
The opening time of block；If it is determined that location data is not obtained when MDT starts, then locating module in advance
Opening time.Wherein, it is worth mentioning at this point that, the locating module opening time the latest is opened earlier than MDT
The time of beginning.
So, according to the actual acquisition situation of location data, the time that can be opened with dynamic adjustment locating module,
It is better suited for network environment at that time, it is ensured that while MDT is smoothly tested so that locating module
Opening time is shorter.
Step 208, postpones the opening time of locating module.
Specifically, if GPS location acquisition of information success, then mean GPS module
Opening time is still partially early, and the opening time of GPS module further can also step back.
Step 209, in advance opening time of locating module.
Specifically, if GPS location acquisition of information is unsuccessful, it may be possible to caused by environmental factorss
The time for obtaining GPS location information is longer, it is meant that the opening time of GPS module is partially late, so carrying
The opening time of prelocalization module, increase the time for obtaining location data.
It should be noted that in above-mentioned steps 208 and 209, the locating module opening time the latest with
The difference of the time that MDT starts is locating module from being opened into the minimum duration that obtains location data；Positioning
The difference of the time that module earliest opening time and MDT start is locating module is determined from being opened into
The maximum duration of position data.That is, arranging bound to the opening time of locating module, open earliest
Open and the time range opened the latest is locating module from the minimum duration for obtaining location data being opened into most
Big duration, it is of course also possible to appropriate increase some surpluses (such as on minimum duration and maximum duration
Minimum duration is if if 3 seconds, then the difference lower limit of the time after adjustment can be set as 4 seconds).
Because the time is too short, locating module inadequate time obtains location data, and overlong time, then explanation be by
In environmental factorss cause location data obtain less than, be not required to it is unrestricted in advance.
It is noted that in above-mentioned dynamic adjustment step, when the duration of adjustment can be same every time
It is long, such as it is set to the minima of the DRX cycle of terminal.
, used as unit time, carrying out opening time adjustment with this can be in order to control for the same duration.
Certainly, in actual applications, it is also possible to do not perform above-mentioned steps 207 to 209, it is that is, not right
Ta enters Mobile state adjustment, and the MDT steps in such present embodiment more will simplify.
Step 210, closes locating module.
Specifically, locating module is closed after location data is got.
Above-mentioned steps 201 to 210 are the flow process of a MDT, and one group of measurement can be obtained after being finished
Data, these data are probably various measurement data of this cell and multiple adjacent cells.And terminal is held
During row MDT, generally require and continuously perform several times, so subsequent step also needs to determine whether MDT
Whether terminate.
Step 211, judges whether MDT terminates；If so, then execution step 212；If it is not, then returning
Execution step 201.
Step 212, report network after data splitting.
Specifically, it is after MDT processes terminate, high-rise by the measurement result and positioning of all collections
Information reports network after being organized into message.
Embodiment of the present invention in terms of existing technologies, changes the normally opened shape of existing locating module
State, and start front opening in each MDT, closed after location data is obtained immediately, at other periods
In power-saving working mode, the power consumption of locating module is greatly reduced.In addition, to ensure during MDT measurements
Location data with the same time, so being opened using locating module in advance, it is ensured that when MDT is measured
Synchronization gain location data.Meanwhile, the minimum road measuring method in embodiment of the present invention is not required to extra
Hardware supported, does not almost increase computational complexity yet, realize it is easy, beneficial to being widely popularized.Additionally,
How long open in advance that on earth GPS module can be caused in physical layer between certain to determine
The accurate location information of GPS is obtained when measuring, present embodiment employs dynamic adjustment
Method, allows this Initial Lead Adaptive in network environment at that time, reaches a relatively accurate numerical value.
Meanwhile, decline the accuracy of location information, increased very big motility on the contrary, be conducive to
The managing electric quantity of mobile terminal so that user is reduced to the repellency of this task of MDT, is conducive to moving
Dynamic operator obtains a large amount of useful metrical informations with less cost, provides effectively ginseng for the network optimization
Examine data.
It is noted that by the use of d GPS locating module as locating module in present embodiment, and in reality
In border, GPS GLONASS locating module, the Big Dipper alignment system can also be utilized
, used as locating module, here will not enumerate for BDS locating modules or Galileo locating module.
Second embodiment of the present invention is related to a kind of minimum road measuring method.Second embodiment is
Do on the basis of one embodiment and further improved, mainly theed improvement is that：The present invention second is implemented
Disarmed state be increased for locating module in mode, for due to environmental factorss cause location data cannot
During acquisition, locating module is made to enter disarmed state.Locating module invalid unlatching in a short time is avoided, enters one
Step saves the power consumption of locating module.
It was found by the inventors of the present invention that during adjustment locating module is opened, if opened in MDT
During the beginning, location data is not got, although obtain GPS location caused by being likely due to environmental factorss
The time of information is longer, but there is also alternatively possible, and such as locality does not have gps signal (such as indoor
In environment or tunnel), now the upper limit is set can to the opening time in advance, be set to GPS module
From opening to most-likely time for obtaining GPS location information, it is also possible to along with a small amount of surplus (ratio
If maximum time is if 20 seconds, then MAX is just set as 21 seconds), if greater than this time
Still if there is no location information, then just very likely locality does not have gps signal for explanation, then
It is accomplished by longer time and need not opens GPS module, saves electricity.
Specifically, if the opening time of the locating module after adjustment is the earliest opening time, and working as
When secondary MDT starts, it is judged to that location data is not obtained, then closes locating module, and make locating module
Into the disarmed state of preset duration.
That is, when the opening time in advance has been adjusted to the upper limit, but MDT when starting still without
Method gets location data, and just now location data cannot get acquiescence, and as localizing environment changes
Become relatively slow, even if so locating module is again turned in a short time, cannot also get location data, this
The unlatching of location data cannot be got several times just into invalid unlatching.So being positioning in present embodiment
Module is additionally arranged disarmed state, and locating module is not turned in disarmed state.
In actual applications, disarmed state can be controlled using intervalometer, concrete control method is such as
Under：
One positioning inactivity timer (referred to as " Ti ") is set, is judging that GPS location information cannot obtain
Open when obtaining, simultaneously close off d GPS locating module, and GPS location is again started up when Ti is overtime
Module shifts to an earlier date opening timing device.Specifically, the length of the intervalometer of Ti is then set to MDT intervalometers
The integral multiple of length, such as could be arranged to 4 times according to engineering experience.
Correspondingly, can comprise the steps of the step of opening locating module before：
Whether detection locating module is in disarmed state；When confirming to be not in disarmed state, unlatching is performed
The step of locating module.
If so when confirming to make environmental factorss cause location data obtain, it is to avoid locating module is short
It is again turned in phase, further saves the power consumption of locating module.
Third embodiment of the present invention is related to a kind of minimum road measuring method.3rd embodiment is
Do on the basis of one embodiment and further improved, mainly theed improvement is that：The present invention the 3rd is implemented
In mode before MDT starts, the time interval of MDT is estimated, if time interval is too small,
Even if network environment is splendid, locating module cannot also obtain location data in this time interval, then
Just forbid the switching manipulation of locating module so that the minimum road measuring method in the present invention is adapted to difference
Demand, it is ensured that the carrying out of MDT under various demands, can be ensured.
Minimum road measuring method in present embodiment is as shown in figure 3, specific as follows：
Step 301, judges that whether the time interval of MDT gets positioning from being opened into more than locating module
Minimum duration needed for data.If so, then execution step 314；If it is not, then execution step 302.
That is, if it is decided that more than minimum duration, then need to carry out the opening and closing of locating module afterwards.
If it is less, it is normally opened to be held in position module.Due to MDT time intervals it is too small when, its interval is not enough
So that locating module gets location data, that also need not just turn off locating module.
