DESCRIPTION OF EMBODIMENTS
To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. The described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
FIG. 1 is a schematic flowchart of Embodiment 1 of a method for predicting a position of a mobile user according to the present disclosure. The method for predicting a position of a mobile user provided in this embodiment may be implemented using user equipment, where the user equipment may be implemented using software and/or hardware. As shown in FIG. 1, the method for predicting a position of a mobile user provided in this embodiment includes the following steps:
Step 101: Determine an occurrence probability of a current behavioral activity of a mobile user.
Step 102: Determine an occurrence probability of a target behavioral activity of the mobile user according to the occurrence probability of the current behavioral activity of the mobile user, a historical activity migration rule of the mobile user, and a public activity migration rule.
Step 103: Determine the target behavioral activity of the mobile user according to the occurrence probability of the target behavioral activity of the mobile user.
Step 104: Predict a target geographical position of the mobile user according to the determined target behavioral activity of the mobile user.
In a specific implementation process, the user equipment determines the target geographical position of the mobile user, where the target geographical position refers to a destination that the mobile user may need to go next when being located in a current geographical position. For example, when the target geographical position of the mobile user is predicted as a frequently visited shopping center, information about discounts and sales promotion of a shop may be pushed to the mobile user in advance, which saves time of the user and also improves user experience, or when the target geographical position of the mobile user is known as home, the mobile user is reminded to buy flour on the way back from work, and turn on an air conditioner at home by means of remote control, and in addition, traffic status of road sections are sent to the user equipment.
A person skilled in the art may understand that the foregoing embodiment describes only some application processes of the target geographical position of the mobile user, but not all application processes, and for other application processes of the target geographical position of the mobile user, details are not described in this embodiment again.
The following describes in detail how to determine the target geographical position of the mobile user in this embodiment.
In step 101, the user equipment first determines the occurrence probability of the current behavioral activity of the mobile user, which may be implemented in the following possible implementation manners:
One possible implementation manner is to acquire a current geographical position and current time of the mobile user, determine, according to the current geographical position, distribution of a point of interest that is of the mobile user and within a second preset geographical position range, and determine the occurrence probability of the current behavioral activity of the mobile user according to the current time and the distribution of the point of interest.
Behavioral activities of the mobile user in daily life are dining, working, shopping, and the like, and it is assumed that there are M kinds of behavioral activities, where M is a natural number. Each behavioral activity is corresponding to one point of interest (POI), and the point of interest may be a restaurant, a mall, an office building, and the like, where it is assumed that there are N kinds of points of interest, and N is a natural number.
Particularly, there is a correspondence between the current time, each of the point of interest, and an occurrence sub-probability of the current behavioral activity. The correspondence may be indicated using a condition occurrence probability p(Acti|POIk,T), where Acti represents the occurrence sub-probability of the current behavioral activity of the mobile user, POIk represents the point of interest, and T represents the current time, which may be shown in table 1, where the occurrence sub-probability of the current behavioral activity of the mobile user may be an empirical value given by an expert, or may be acquired by means of statistics according to collected multiple historical activity records of the mobile user.

When the current time is in the time period from 8:00 to 11:30, as shown in table 1, when the point of interest is the office building, an occurrence sub-probability that the current behavioral activity of the mobile user is dining is 0.05, an occurrence sub-probability of working is 0.9, and an occurrence sub-probability of shopping is 0.05.
Because many points of interest exist in the second preset geographical position range that is relative to the current geographical position of the mobile user, a ratio of the point of interest is determined according to the distribution of the point of interest, and the occurrence probability of the current behavioral activity of the mobile user at the current time is determined according to the ratio of the point of interest, and an occurrence sub-probability of the current behavioral activity corresponding to each of the point of interest.
All the points of interest in the second preset geographical position range are obtained by searching according to coordinates of the current geographical position of the mobile user, and relative to all the points of interest, occurrence sub-probabilities of the same current behavioral activity are summed to obtain the occurrence probability of the current behavioral activity in the current geographical position, as shown in formula 1:

Acti represents the occurrence sub-probability of the current behavioral activity of the mobile user, POIk represents the point of interest, T represents the current time, Loc represents the current geographical position, and N represents a quantity of points of interest. Pk is a ratio of a quantity of points of interest that are of a same type to all the points of interest, where pk (0≦pk≦1). For example, when the point of interest is restaurant, Pk is 0.4, when the point of interest is mall, Pk is 0.3, and when the point of interest is office building, Pk is 0.3.
When the current time is in the time period from 8:00 to 11:30, and the current behavioral activity is dining, the occurrence probability of the current behavioral activity is P=0.4×0.5+0.3×0.3+0.3×0.05=0.305, when the current behavioral activity is working, the occurrence probability of the current behavioral activity is P=0.4×0.5+0.3×0.1+0.3×0.9=0.5, and when the current behavioral activity is shopping, the occurrence probability of the current behavioral activity is P=0.4×0+0.3×0.6+0.3×0.05=0.195.
Another possible implementation manner is to acquire sense data corresponding to the mobile user, determine a motion state of the mobile user according to the sense data, and determine the occurrence probability of the current behavioral activity of the mobile user according to the motion state of the mobile user.
The motion state (motionless, walking, riding) of the mobile user is determined using a motion sensor (such as an acceleration sensor or a gyroscope) on the user equipment, or it is determined, using a light sensor, a barometer, and a Global Position System (GPS), whether the current geographical position of the mobile user is indoor/outdoor. The motion state of the mobile user is determined by comprehensively applying the foregoing various types of sense data and by means of occurrence probability reasoning, rule reasoning and the like, and the occurrence probability of the current behavioral activity of the mobile user is determined according to the motion state of the mobile user. A person skilled in the art may understand that there is a correspondence between the motion state and the occurrence probability of the current behavioral activity of the mobile user, and the occurrence probability of the current behavioral activity may be determined according to the correspondence.
Still another possible implementation manner is to acquire a background voice of the current geographical position of the mobile user, and determine the occurrence probability of the current behavioral activity of the mobile user according to the background voice.
The background voice of the mobile user is collected using a microphone of the user equipment, and a special sound is identified or a scenario analysis is performed by preprocessing data of the background voice and extracting a Mel frequency cepstrum coefficient (MFCC), a zero-crossing rate, short-time energy, and the like. Therefore, an activity of the mobile user may be speculated according to the background voice. If an impact sound of tableware appears in the background voice, the current behavioral activity of the mobile user is determined as dining, and if there is a sound that multiple people are having a discussion at the same time, the current behavioral activity of the mobile user is determined as a meeting. A person skilled in the art may understand that there is a correspondence between the background voice and the occurrence probability of the current behavioral activity of the mobile user, and the occurrence probability of the current behavioral activity may be determined according to the correspondence.
In step 102, the occurrence probability of the target behavioral activity of the mobile user is determined according to the occurrence probability of the current behavioral activity of the mobile user, the historical activity migration rule of the mobile user, and the public activity migration rule, where the historical activity migration rule includes an occurrence probability, determined according to a historical behavioral activity of the mobile user, that the mobile user is converted from the current behavioral activity to the target behavioral activity, and a weighting factor of the historical behavioral activity, and the public activity migration rule includes an occurrence probability, determined according to a historical behavioral activity of another mobile user, that the mobile user is converted from the current behavioral activity to the target behavioral activity, and a weighting factor of a public behavioral activity.
Detailed description is provided in the following using a specific embodiment.
First, according to a universal public activity migration rule of mobile users, the occurrence probability pcommon(Acti|Acti-1) that the mobile user is converted from the current behavioral activity to the target behavioral activity is obtained, as shown in table 2. The public activity migration rule may be an empirical value given by an expert, or may be acquired by means of statistics according to collected historical activity records of multiple mobile users.

In addition, if the historical activity migration rule is known, the occurrence probability ppersonal (Acti|Acti-1) that the mobile user is converted from the current behavioral activity to the target behavioral activity may also be obtained, where the historical activity migration rule may be obtained through multiple ways, for example, data may be collected by specially developing software that makes the mobile user actively cooperate to annotate the current behavioral activity, or may be obtained using a check-in service in a third-party location based service (LBS) that is once used by the mobile user, or may be extracted from a recorded electronic diary of the mobile user, and a schedule in a calendar. A person skilled in the art may understand that the historical activity migration rule may also be shown as Table 2, and details are not described in this embodiment again.
Then, determining an occurrence probability of a target behavioral activity corresponding to the historical behavioral activity according to the occurrence probability of the current behavioral activity, the occurrence probability, determined according to the historical behavioral activity of the mobile user, that the mobile user is converted from the current behavioral activity to the target behavioral activity, and the weighting factor of the historical behavioral activity may be implemented using the following formula:

If α(t)=0.6, and the historical activity migration rule is also shown as Table 2, when the target behavioral activity corresponding to the historical behavioral activity is shopping, the occurrence probability is pl(Actnext=act)=0.6×(0.305×0.4+0.5×0.2+0.195×0)=0.1332, when the target behavioral activity corresponding to the historical behavioral activity is dining, the occurrence probability is pl(Actnext=act)=0.6×(0.305×0+0.5×0.8+0.195×0.9)=0.3453, and when the target behavioral activity corresponding to the historical behavioral activity is working, the occurrence probability is pl(Acnext=act)=0.6×(0.305×0.6+0.5×0+0.195×0.1)=0.2025.

where, pg(Actnext=act) represents the occurrence probability of the target behavioral activity corresponding to the public behavioral activity, (1−α(t)) represents the weighting factor of the public behavioral activity, pcommon(Actnext=act|Actcurrent=bi) represents the occurrence probability, determined according to the historical behavioral activity of the other mobile user, that the mobile user is converted from the current behavioral activity to the target behavioral activity, M represents a quantity of behavioral activities, and M is a natural number.

In a specific implementation process, for an implementation manner of determining the occurrence probability of the target behavioral activity corresponding to the public behavioral activity, reference may be made to an implementation manner of determining the occurrence probability of the target behavioral activity corresponding to the historical behavioral activity, and details are not described herein again.
A person skilled in the art may understand that α(t) is the weighting factor, and α(t) increases with time, because as time goes by, collected information about a user activity rule continuously increases, and a personal activity rule may gradually play a leading role in a prediction.
Finally, the occurrence probability of the target behavioral activity of the mobile user is determined according to the occurrence probability of the target behavioral activity corresponding to the historical behavioral activity and the occurrence probability of the target behavioral activity corresponding to the public behavioral activity.
In a specific implementation process, the occurrence probability of the target behavioral activity corresponding to the historical behavioral activity and the occurrence probability of the target behavioral activity corresponding to the public behavioral activity are summed in a case in which a same current behavioral activity is converted into a same target behavioral activity such that the occurrence probability P(Actnext=act) of the target behavioral activity of the mobile user is obtained, that is,

p(Actnext=act)=Pl(Actnext=act)+Pg(Actnext=act)  (Formula 4)

In step 103, the target behavioral activity of the mobile user is determined according to the occurrence probability of the target behavioral activity of the mobile user.
A target behavioral activity with a maximum occurrence probability is selected as the target behavioral activity.
In step 104: the target geographical position of the mobile user is predicted according to the target behavioral activity of the mobile user.
It is determined whether the target behavioral activity of the mobile user exists in a historical behavioral activity record of the mobile user, where the historical behavioral activity record includes a historical geographical position corresponding to the target behavioral activity, if the target behavioral activity of the mobile user exists in the historical behavioral activity record of the mobile user, the target geographical position of the mobile user is predicted according to the historical behavioral activity record, and if the target behavioral activity of the mobile user does not exist in the historical behavioral activity record of the mobile user, the target geographical position of the mobile user is predicted according to a geographical position that is within a first preset geographical position range and corresponding to the target behavioral activity.
In a specific implementation process, the historical behavioral activity record includes a historical geographical position that is once visited by the mobile user. When the target behavioral activity exists in the historical behavioral activity record, the target geographical position of the mobile user is predicted according to the historical geographical position that is once visited by the mobile user, that is,
