Description
Technical Field
The present invention relates to an information processing method, and more particularly, to a method for switching geographical locations on a mobile terminal.
Background
With the popularization of intelligent mobile terminals, Location Based Services (LBS) have been rapidly developed, and many mainstream applications developed based on mobile terminals provide location based services. For example, when the user's location changes from the Hangzhou location of Beijing, the local news recommended and provided by the today's leading APP will be adjusted from the local news of Beijing to the local news of Hangzhou city; the food recommended and provided by the popular comment APP is adjusted from the catering place in Beijing city to the catering place in Hangzhou city.
However, there are still some problems with current location-based services. For example, when a user travels from Beijing to Hangzhou on a train, if the user's location on the road is Texas City, when the user turns on news-like APPs, these APPs will provide local news of Texas City, or pop up a prompt asking the user whether to switch the location from Beijing to Texas. Obviously, for the vast majority of users from Beijing to Hangzhou, there is no relation to news or other conditions in some cities on the road. Therefore, the LBS provided by the APP is not intelligent enough, thereby affecting the experience of the user during the trip.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The invention provides a method for switching geographical positions on a mobile terminal. The mobile terminal is generally defined as a smart phone or a tablet computer capable of running APP, and particularly includes but is not limited to apple, wary, millet, OPPO, VIVO, association, zhongxing, knonia and other brands of smart phones.
According to the invention, the mobile terminal comprises a position buffer queue and a region buffer. The position buffer queue can be physically realized in a storage area without losing data when power is down, such as a storage space of the mobile terminal; the position buffer queue may be logically implemented as a sequential queue or a circular queue. The present invention is not intended to limit the physical and logical implementation of the position buffer queue, and those skilled in the art will appreciate that any type of queue in the prior art can be used as the position buffer queue of the present invention, and will also fall into the protection scope of the present invention.
According to the invention, the mobile terminal stores the geographical coordinates of the mobile terminal in the location buffer queue every fixed time T (e.g. 10-20 minutes, preferably 15 minutes), thereby forming a schematic diagram of the location buffer queue as shown in fig. 1. Taking T as an example of 15 minutes, if the time when the mobile terminal stores P1 in the location buffer queue is 12:00 am, the storage time of P2 is 11:45, the storage time of P3 is 11:30, and so on. Further, the position buffer queue stores the storage time T1 of P1, in the foregoing example, T1 is 12: 00.
According to the present invention, the mobile terminal further includes a region cache, similar to the location cache queue, and the present invention is not intended to limit the physical implementation and the logical implementation of the region cache, and those skilled in the art know that any type of cache in the prior art can be used as the region cache of the present invention, and will also fall into the protection scope of the present invention. Preferably, the region cache is implemented as a profile table.
As shown in fig. 2A, the area cache stores an ID of an APP and an APP area installed in the mobile terminal, where the ID of the APP is an ID of a unique identifier APP, and the APP area is an area where the mobile terminal is located when the APP runs last time. Take the first record as an example, where APPID is ID-1 (exemplary ID-1 may represent that APP is "today's head of things" APP), and APP area is "beijing", which means that the user of the mobile terminal has used "today's head of things" APP last time and the area is "beijing".
According to the invention, when the user starts the APP, as shown in fig. 3, the mobile terminal performs the following steps of switching the geographical location:
step S100, reading an APP area started by a user from an area cache; specifically, when a user starts an APP (for example, the first APP of today), a unique ID (for example, ID-1) of the APP can be obtained, and then a corresponding APP region (for example, beijing) is searched in the region cache. Reading a first geographic coordinate P from a location cache queue1＝{x1,y1Specifically, the first geographic coordinate P1 is the last position coordinate in the position buffer queue.
In step S200, if P1 is in the APP area, for example, the coordinates of P1 are also in "beijing", the mobile terminal does not need to perform a handover of the geographic location. Conversely, if P1 is not within the APP region, such as P1 as being located within "Zheng", then the mobile reads the second geographic coordinate P from the location cache2＝{x2,y2And a second geographic coordinate P2 is the penultimate position coordinate in the position buffer queue.
Step S300, the mobile terminal judges ifThere is a great probability that the user does arrive at zheng from beijing, for example, and therefore switches the user-initiated APP to the area where P1 is located, for example, from "beijing" to "zheng. On the contrary, ifThere is a great probability that the user simply passes "zheng", for example, the user is from "beijing" to "wuhan", and thus the mobile terminal does not perform a handover of the geographical location.
According to one embodiment of the invention v is an empirically set velocity constant, preferably having a value of more than 50 km/h.
According to another embodiment of the invention, v is a dynamically acquired velocity constant. In particular, the method comprises the following steps of,wherein,n is the number of locations stored in the location buffer queue, k is v with a calculated value other than 0iNumber of (a), v0Threshold for speed discrimination (preferably 450km/h) { xi,yiAnd { x }i+1,yi+1Pi and Pi + 1. In the embodiment, the dynamic velocity constant v is calculated through the historical position, so that the value of v can be more accurate, and the value of v is calculated through v0The setting of (3) can effectively eliminate the historical noise caused by closing the position information function within a certain period of time.
Through the steps, when the area is changed, the mobile terminal can automatically judge whether the user really arrives at the destination or is in the process of traveling with high accuracy. And whether the geographic position needs to be switched or not is judged according to the judgment, so that the user experience is improved.
According to the present invention, further, the step S300 further includes updating the area cache by using the area where P1 is located after the switching of the geographic location is completed. In the foregoing example, "zheng" was used to update "beijing" as shown in fig. 2B.
According to the invention, further, Q fixed point (such as railway station) area information is stored in the mobile terminal, and each fixed point area information comprises fixed point coordinates (such as central coordinates of the railway station), a first radius R and a second radius R, wherein R > R.
Further, step S300 in the present invention is replaced with step S400, and step S400 includes:
step S410, ifThen the current position information P is acquired0＝{x0,y0}。
Step S420, in Q fixed point region information, inquiring and P0Closest fixed point coordinate Pm＝{xm,ym}。
Step S430, ifAnd isThen the user-initiated APP is not switched to the area where P1 is located; otherwise, the user-initiated APP is switched to the area where P1 is located.
Through the steps S410-S430, the situation that the train has a long stop time (for example, more than 5-10 minutes) in the railway station can be effectively avoided.
According to the present invention, further, the position buffer queue further includes a time T1 storing the first geographic coordinate P1. The step S100 further includes: obtaining the current time T0 of the mobile terminal, and reading the time T1 from the position buffer queue; if T0-T1 > Δ T, the user-initiated APP is switched to the area where the current location is, and the subsequent steps are not performed, while the location cache queue is emptied. Wherein, the delta T is a time threshold value, and the preferable value is more than 60 minutes. Through the mode, the situation that the user flies from one city to another city by taking the plane can be effectively identified. That is, the flight time of most airplanes is generally not less than 60 minutes, and the mobile terminal is required to be closed or placed in the flight mode on the airplane, and no matter which situation, the mobile terminal cannot normally obtain and store the location information within the time interval T, and most of the flight cities are destination cities, so that the APP started by the user is switched to the area where the current location is located under the condition that the above mode is met, and the user experience of most users can be effectively improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are within the scope of the present invention.
