Fig. 2 is the flow chart of a kind of localization method that the embodiment of the present invention provides.The executive agent of this inventive embodiments is mobile terminal, and see Fig. 2, the method comprises:
201, when mobile terminal receives positioning instruction, judge whether buffer memory positioning result, if so, obtain the positioning result of buffer memory, terminate, if not, perform step 202.
Wherein, this mobile terminal can be the equipment such as mobile phone, panel computer, and this positioning instruction can be opened the operation triggering of map application by this mobile terminal, or is searched the operation triggering of neighbouring cuisines by this mobile terminal, or operate triggering by other, the embodiment of the present invention does not all limit this.
In embodiments of the present invention, after this mobile terminal receives this positioning instruction, can positioning action be performed, obtain positioning result.Particularly, this mobile terminal can adopt GPS (GlobalPositioningSystem, global positioning system) mode that the mode, the mode of architecture or the WIFI (WirelessFidelity, Wireless Fidelity) that locate locate, perform positioning action.And this mobile terminal locates the accuracy of geographical location information that the locator data obtained can comprise geographical location information and obtain, the scope belonging to difference between the geographical location information that this accuracy obtains for the actual geographic positional information and location representing this mobile terminal, namely represent this mobile terminal be in this geographical location information be the center of circle, this accuracy is in the determined border circular areas of radius.This geographical location information can represent with the form of latitude and longitude coordinates, or represents with the form of the address name of geographical location information, and the present embodiment does not all limit this.
In embodiments of the present invention, when this mobile terminal performs positioning action at every turn, can the positioning result that gets of buffer memory, then when this mobile terminal receives positioning instruction, can not start immediately to perform positioning action, but first judge whether buffer memory positioning result, if this mobile terminal is buffer memory positioning result, then the positioning result of this acquisition for mobile terminal buffer memory, and without the need to performing positioning action, if the non-buffer memory positioning result of this mobile terminal, then start to perform positioning action.
During practical application, As time goes on, this mobile terminal may move, and especially, elapsed time is longer, and the distance of this mobile terminal movement may be larger.And in embodiments of the present invention, the positioning result that the positioning result of this mobile terminal buffer memory obtains when being last execution positioning action, if this mobile terminal execution on once positioning action just receive this positioning instruction for a long time, position residing when then this mobile terminal receives this positioning instruction is far with positional distance when performing last positioning action, now, if the positioning result obtained when being performed positioning action the last time is as this positioning result, positioning result mistake can be caused, affect setting accuracy.
In order to avoid the problem of above-mentioned positioning result mistake, when this mobile terminal gets positioning result at every turn, according to preset buffer memory duration, this positioning result of buffer memory, namely this mobile terminal is when starting this positioning result of buffer memory, start timing, when the duration added up reaches this preset buffer memory duration, this positioning result is deleted.So, if this mobile terminal execution on once positioning action just receive this positioning instruction for a long time, when this mobile terminal judge whether buffer memory positioning result time, the positioning result of buffer memory is deleted by this mobile terminal, namely this mobile terminal can determine non-buffer memory positioning result, now, this mobile terminal starts the positioning action performing this.Wherein, this preset buffer memory duration can be pre-determined by this mobile terminal, and can be 2s, 5s etc., the embodiment of the present invention limit this.
The embodiment of the present invention is by buffer memory positioning result in preset buffer memory duration, when this mobile terminal frequently receives positioning instruction at short notice, without the need to performing positioning action continually, directly obtaining the positioning result of buffer memory, saving Internet resources and the electricity of this mobile terminal.And when this mobile terminal just receives positioning instruction after exceeding this preset buffer memory duration, then start to perform positioning action, obtain more accurate positioning result.
It should be noted that, when practical application, this positioning action can be performed by the localization of this mobile terminal.For each application that this mobile terminal is installed, after this application receives positioning instruction, this localization can be started, positioning action is performed by this localization, obtain locator data, afterwards, this locator data is sent to this application by this localization, and this application can using this locator data as positioning result.
Further, in order to avoid same application starts localization at short notice continually, this mobile terminal is each application memory allocated space of installing, this memory space is used for buffer memory positioning result, for each application, when this application gets the positioning result that this localization returns, in the memory space of this application, this positioning result of buffer memory.When this application receives positioning instruction, directly can not start localization, but first judge whether store location result in the memory space that distributes, if store location result in this memory space, then this application directly obtains this positioning result, and do not restart this localization, if non-store location result in this memory space, then this localization of this application start, the positioning result obtained is located to obtain this localization, in this memory space, the positioning result that this location of buffer memory obtains.
202, this mobile terminal starts to perform positioning action, and start timing, the any instant before the first preset duration is reached at the duration of statistics, when getting the first locator data, judge that whether this first locator data meets that this is first pre-conditioned, if so, performs step 203, if not, step 204 is performed.
Wherein, this first preset duration is for specifying that this mobile terminal first time obtains the duration of locator data, can be 3s, 5s etc., this is first pre-conditioned for limiting the locator data got in this first preset duration, the default accuracy that can comprise locator data, duration of expending etc., this first preset duration and this first pre-conditionedly all can be determined according to location requirement by this mobile terminal, the embodiment of the present invention does not limit this.
Alternatively, this first pre-conditioned accuracy for locator data is greater than default accuracy, this default accuracy can be 100 meters, 50 meters etc., or, this first pre-conditionedly can not also comprise any condition, namely this mobile terminal can not also limit the locator data got in this first preset duration, and the embodiment of the present invention first pre-conditionedly not to limit this.
When this mobile terminal starts to perform positioning action, start timing, As time goes on, the duration of statistics is also increasing gradually.Reach any instant before this first preset duration at the duration of statistics, if this acquisition for mobile terminal is to the first locator data, then judge whether this first locator data meets that this is first pre-conditioned.
When this first pre-conditioned accuracy for locator data is greater than default accuracy, this mobile terminal judges whether the accuracy of this first locator data is greater than this default accuracy, if, determine that this first locator data meets that this is first pre-conditioned, if not, determine that this first locator data does not meet that this is first pre-conditioned.
203, this first locator data is retrieved as positioning result by this mobile terminal, according to preset buffer memory duration, and this positioning result of buffer memory, and stop this positioning action, terminate.
If this first locator data meets, this is first pre-conditioned, then represent the locator data having got and satisfied the demands, then this first locator data is retrieved as positioning result by this mobile terminal, now, this mobile terminal can stop this positioning action, no longer obtains locator data.And in order to avoid again positioning getting in the short time after this positioning result, this mobile terminal can also according to this preset buffer memory duration, this positioning result of buffer memory.
In addition, when this acquisition for mobile terminal is to positioning result, operation can be processed accordingly to this positioning result, this process operates to comprise and operates the display of this positioning result, or to the query manipulation etc. of the information that this positioning result is associated, the present embodiment does not limit this.When running map application as current, in the map of display, show this positioning result.Or, current when searching neighbouring cuisines, according to this positioning result, inquire about the detail information in the restaurant in this positioning result preset range.
It should be noted that, in embodiments of the present invention, locator data is different from positioning result.Locator data refers to the locator data that this mobile terminal obtains when performing positioning action, this locator data comprises the geographical location information of locating and obtaining, this mobile terminal can get one or more locator data, but can not carry out the process operations such as display to this locator data.And this positioning result refers to the locator data that this mobile terminal is chosen from the one or more locator datas obtained, when this acquisition for mobile terminal is to positioning result, directly can process operation accordingly to this positioning result.
That installs with this mobile terminal is applied as example, and this application can be selected a locator data, as positioning result, then positioning result be returned to operation layer, be shown by operation layer to this positioning result after getting the locator data that localization returns.
204, this first locator data of this mobile terminal buffer memory, and continue to perform this positioning action, when the duration added up reaches the first preset duration, if also do not get satisfied first pre-conditioned locator data, then this first locator data of buffer memory is retrieved as positioning result, and continues to perform this positioning action.
If this first locator data does not meet, this is first pre-conditioned, then this first locator data of this mobile terminal buffer memory, and continue to perform this positioning action, until when the duration of statistics reaches this first preset duration, judge whether to get and meet this first pre-conditioned locator data, meet this first pre-conditioned locator data if got, then meet this first pre-conditioned locator data as positioning result using what get, and stop this positioning action.
When the duration of statistics reaches this first preset duration, if this mobile terminal does not also get meet this first pre-conditioned locator data, then extract this first locator data of buffer memory, this first locator data is got positioning result, now, this mobile terminal does not stop this positioning action, but continues to perform positioning action, to obtain positioning result in subsequent process.
Wherein, the duration of this this first locator data of mobile terminal buffer memory can be pre-determined by this mobile terminal, and the duration of this first locator data of buffer memory can be greater than this first preset duration, and the embodiment of the present invention does not limit this.
Receive positioning instruction for the application of the current operation of mobile terminal, localization performs positioning action, if before the duration of statistics reaches this first preset duration, this application gets the first locator data that this localization returns, then judge whether this first locator data meets that this is first pre-conditioned, if this first locator data meets, this is first pre-conditioned, then this first locator data is retrieved as positioning result, according to preset buffer memory duration, this positioning result of buffer memory, and close this localization, this localization no longer performs positioning action.If this first locator data does not meet, this is first pre-conditioned, then this first locator data of buffer memory, now, this localization continues to perform positioning action.When the duration added up reaches the first preset duration, if this application does not also get satisfied first pre-conditioned locator data, then this first locator data of buffer memory is retrieved as positioning result, and this localization is not closed in this application, then this localization continues to perform this positioning action.
It should be noted that, if before the duration of statistics reaches this first preset duration, this acquisition for mobile terminal has arrived multiple locator data, but do not get and meet this first pre-conditioned locator data, then when the duration added up reaches this first preset duration, this mobile terminal from multiple locator data, can choose the locator data that accuracy is maximum, as positioning result, and continue to perform positioning action.
In addition, this mobile terminal, in this first preset duration, does not get any locator data, then, when the duration added up reaches the first preset duration, this mobile terminal does not get positioning result, and continues to perform positioning action.
205, before the duration of statistics reaches the second preset duration, if this acquisition for mobile terminal is to the second locator data, judges that whether this second locator data meets second pre-conditioned, if so, perform step 206, if not, perform step 207.
In the embodiment of the present invention, this second preset duration is greater than this first preset duration, total duration that this second preset duration is used for performing this mobile terminal positioning action limits, can be 30s, 50s etc., concrete numerical value can be pre-determined by this mobile terminal, and the embodiment of the present invention does not limit this.
After the duration of statistics is greater than this first preset duration and before reaching this second preset duration, if this acquisition for mobile terminal is to the second locator data, judge whether this second locator data meets second pre-conditioned.
Wherein, this second pre-conditionedly can be greater than the accuracy of this first locator data for the accuracy of locator data.That is to say, when the duration added up reaches this first preset duration, this mobile terminal using this first locator data as positioning result, then when this acquisition for mobile terminal follow-up is to the second locator data, judge whether the accuracy of this second locator data is greater than the accuracy of this first locator data, if the accuracy of this second locator data is greater than the accuracy of this first locator data, then determine that this second locator data meets that this is second pre-conditioned, if the accuracy of this second locator data is not more than the accuracy of this first locator data, then determine that this second locator data does not meet that this is second pre-conditioned.
In addition, if before the duration of statistics reaches this first preset duration, this acquisition for mobile terminal has arrived multiple locator data, and when the duration added up reaches this first preset duration, using the appointment locator data in the plurality of locator data as positioning result, then this second pre-conditionedly can be greater than the accuracy of this appointment locator data for the accuracy of locator data.When this acquisition for mobile terminal is to the second locator data, judge whether the accuracy of this second locator data is greater than the accuracy of this appointment locator data, if the accuracy of this second locator data is greater than the accuracy of this appointment locator data, then determine that this second locator data meets that this is second pre-conditioned, if the accuracy of this second locator data is not more than the accuracy of this appointment locator data, then determine that this second locator data does not meet that this is second pre-conditioned.
206, this second locator data is retrieved as positioning result by this mobile terminal, and according to preset buffer memory duration, this positioning result of buffer memory, stops this positioning action, terminates.
When this second locator data meet this second pre-conditioned time, this second locator data is retrieved as positioning result by this mobile terminal, and stops this positioning action.And this mobile terminal can also according to this preset buffer memory duration, this positioning result of buffer memory.Namely the locator data of this mobile terminal to buffer memory upgrades, and deletes the first locator data of buffer memory, and this second locator data of buffer memory.
207, this mobile terminal stops this positioning action, sends Location Request, receive the locator data that this server returns to server, as positioning result, terminates.
When this second locator data do not meet this second pre-conditioned time, this mobile terminal stops this positioning action.Now, this mobile terminal can adopt the mode of IP address location to position.Particularly, this mobile terminal sends Location Request to server, this server stores has the corresponding relation between IP address and locator data, when this server receives this Location Request, obtain the IP address of this mobile terminal, according to the corresponding relation stored, obtain the locator data that this IP address is corresponding, send to this mobile terminal, then this mobile terminal receives locator data, using this locator data as positioning result.
Wherein, this server can be the application server with the association of the current operation of this mobile terminal, and this mobile terminal, by this application, sends this Location Request to this application server, obtains the locator data that this application server returns.
In addition, when this mobile terminal does not get arbitrary locator data in this second preset duration, the mode of IP address location also can be adopted to position.
When wireless network breaks down, this mobile terminal can not get locator data in this second preset duration, now, add the mode of IP address location, adopt the mode of IP address location, the Position Approximate residing for this mobile terminal can be judged, as which region in which city, improve position success rate, improve Consumer's Experience.
Receive positioning instruction for the application of the current operation of mobile terminal, localization performs positioning action, suppose that this first preset duration is 5s, this second preset duration is 3s, this default accuracy is 100 meters, the workflow of the embodiment of the present invention can be as shown in Figure 3, see Fig. 3, the workflow of the embodiment of the present invention comprises:
(1) this application start positioning flow, judges whether to be cached with the locator data in preset buffer memory duration, if so, locates successfully, directly using the locator data of buffer memory as positioning result, terminate; If not, start localization, position by localization, and start timing.
(2) localization restoring to normal position data, judge whether accuracy reaches 100 meters, if so, and this locator data of buffer memory, and determine to locate successfully, using the locator data of buffer memory as positioning result, terminate.
(3) add up duration and reach 5s, judge whether get locator data in 5s, if so, using this locator data as positioning result, and continue to wait for the locator data whether getting more pinpoint accuracy in 30s, if not, wait duration to be counted to reach 30s.
(4) add up duration and reach 30s, judge whether get locator data in 30s, if get locator data in 30s, whether the accuracy judging the up-to-date locator data returned is the highest accuracy, if the accuracy of the locator data returned up-to-date is the highest accuracy, this locator data of buffer memory, and determines to locate successfully, using the locator data of buffer memory as positioning result, terminate.If the accuracy of the locator data returned up-to-date is not the highest accuracy, determines to locate successfully, using the locator data of buffer memory as positioning result, terminates.If do not get locator data in 30s, then the mode of IP address location is adopted to position.
The method that the embodiment of the present invention provides, by when starting to perform positioning action, start timing, when the duration added up reaches the first preset duration, if also do not get satisfied first pre-conditioned locator data, then continue to perform this positioning action, and this positioning action can not be stopped, before the duration of statistics reaches the second preset duration, if get satisfied second pre-conditioned locator data, then this locator data is retrieved as positioning result, and stops this positioning action.Two timeout mechanism is adopted to position, if do not get satisfied first pre-conditioned locator data in the first preset duration, then continue to obtain the locator data in the second preset duration, avoid because wireless network signal is bad and cause positioning time longer or wireless network cannot get locator data under the abnormal conditions such as temporary transient disconnection in the first preset duration, improve position success rate.And the rough locator data got in this first preset duration is returned to user, reduce user and wait for and duration spent by positioning result improve Consumer's Experience.Further, when getting positioning result, according to preset buffer memory duration, this positioning result of buffer memory, then when frequently receiving positioning instruction in the short time, avoiding performing positioning action continually, directly obtaining the positioning result of buffer memory, greatly save Internet resources and the electricity of this mobile terminal, provide the user positioning service faster simultaneously.And when this mobile terminal just receives positioning instruction after exceeding this preset buffer memory duration, then start to perform positioning action, obtain more accurate positioning result.
