Description

RELATED APPLICATION(S)

The present application claims priority to Chinese Patent Application No. 202111227218.7, filed Oct. 21, 2021, and entitled “Method, Device, and Computer Program Product for Scheduling Tour Guiding Resources,” which is incorporated by reference herein in its entirety.

FIELD

Implementations of the present disclosure relate to resource scheduling and, more specifically, to a method, a device, and a computer program product for scheduling tour guiding resources in a mobile network.

BACKGROUND

With the development of mobile network technologies, which are now capable of providing increasingly high data transmission speeds, users have been able to access many types of tour guiding services through mobile terminals.

It will be understood that when a mobile terminal is located in different locations in a mobile network, it is expected to receive different tour guiding resources. While receiving tour guiding resources from a server in the mobile network, the service at the mobile terminal may experience delays and/or freezing. In this case, how to pre-schedule tour guiding resources becomes an important research topic.

SUMMARY

Thus, it is desired to develop and implement a technical solution for scheduling tour guiding resources in a mobile network in a more effective manner.

DETAILED DESCRIPTION

Example implementations of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the example implementations of the present disclosure are illustrated in the accompanying drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the implementations illustrated herein. Rather, these implementations are provided in order to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

As used herein, the term “include” and variations thereof mean open-ended inclusion, that is, “including but not limited to.” Unless specifically stated, the term “or” means “and/or.” The term “based on” means “based at least in part on.” The terms “one example implementation” and “one implementation” mean “at least one example implementation.” The term “another implementation” means “at least one additional implementation.” The terms “first,” “second,” and the like may refer to different or identical objects. Other definitions, both explicit and implicit, may be included below.

Referring first to FIG. 1, an application context for an example implementation of the present disclosure is described. FIG. 1 schematically illustrates a block diagram of mobile network 100 according to a technical solution in which a method according to an example implementation of the present disclosure may be used. As shown in FIG. 1, mobile network 100 may include core network layer 110 and wireless access network layer 130. In wireless access network layer 130, mobile terminals 140, . . . , and 142 may communicate via base station 150. With the development of 5G technology, edge computing technology has now been proposed. Edge computing layer 120 may be provided between core network layer 110 and wireless access network layer 130 of mobile network 100. This edge computing layer 120 may include computing device 122 and storage device 124. In this way, certain storage tasks and computing tasks can be migrated closer to wireless access network layer 130 in order to improve the response speed.

A variety of position-based services have been proposed at present. For example, a tour guiding service may be provided to mobile terminals 140, . . . , 142, etc., so that when a user carrying a mobile terminal is within a certain geographic area (e.g., a scenic area, etc.), corresponding tour guiding resources can be provided to the user as the position of the mobile terminal changes. Hereinafter, only a tour guiding application will be used as an example to describe how various tour guiding resources can be scheduled.

FIG. 2 schematically illustrates block diagram 200 of the user distribution within a geographic area according to an example implementation of the present disclosure. As shown in FIG. 2, geographic area 210 may include a plurality of locations, e.g., location 0, location 1, location 2, location 3, location 4, location 5, etc. A plurality of users 220 within geographic area 210 may tour the locations in their respective orders according to their expectations. A user may use mobile terminal 140 provided with the tour guiding application to tour in geographic area 210. As the user approaches location 0, mobile terminal 140 may be provided with an introduction to the location, e.g., a summary introduction, historical figures, historical stories, etc.

However, when mobile terminal 140 is in different locations, the tour guiding resources expected to be received will be different, which results in possible delays and/or freezing when the user receives new tour guiding resources. At present, technical solutions have been proposed to pre-load various resources to edge computing layer 120. However, a large number of users in the scenic area will keep moving, which makes it difficult to determine the location that a user will arrive at in the future and thus difficult to pre-determine the resource scheduling strategy.

To address the shortcomings in existing technical solutions, example implementations of the present disclosure provide a technical solution for scheduling tour guiding resources in a mobile network. In this technical solution, locations that the current plurality of users will visit at future times may be predicted based on historical routes of a plurality of historical users. Further, tour guiding data associated with the locations to be visited may be pre-scheduled. Hereinafter, an overview of the scheduling of tour guiding resources will be described with reference to FIG. 3. FIG. 3 schematically illustrates block diagram 300 for scheduling tour guiding resources in a mobile network according to an example implementation of the present disclosure.

As shown in FIG. 3, historical data set 310 may be acquired. This historical data set 310 may include a plurality of historical routes 312 of movement of a plurality of historical users within geographic area 210. Here, historical route 312 may include at least a portion of a plurality of locations within the geographic area. Assuming that the tour guiding application is configured to provide tour guiding services of the Forbidden City, and that the Forbidden City includes a plurality of scenic spots: the Meridian Gate, the Hall of Supreme Harmony, the Hall of Central Harmony, the Hall of Preserving Harmony, the Palace of Heavenly Purity, the Hall of Mental Cultivation, the Imperial Garden, etc. Here, since users may only visit their favorite scenic spots, each historical route may include a portion of the scenic spots arranged in a different order.

Further, based on the plurality of historical routes 312 and current user distribution 320 of the plurality of users within geographic area 210, future user distribution 330 of the plurality of users at a future time point may be determined, respectively. Tour guiding resources may be scheduled between core network layer 110 and edge computing layer 120 based on future user distribution 330. Specifically, assuming that a large number of users are going to the Imperial Garden and that there are no tour guiding resources associated with the Imperial Garden in edge computing layer 120 at this moment, then tour guiding resources for the Imperial Garden may be pre-loaded to edge computing layer 120. With the example implementation of the present disclosure, the future movement trajectories of most users can be predicted in a more accurate manner based on historical routes, and thus the future position predictions of the users can be accurately estimated, thereby achieving the purpose of pre-loading required tour guiding resources.

According to an example implementation of the present disclosure, historically used tour routes may be used as a training data set to acquire preference information about users' visiting trends and behaviors. When learning users' preferences from the training data set, a posteriori probability may be predicted based on the Bayesian method and using probability statistics. In a specific application context, the Bayesian method may be used to predict the next location that each visitor is likely to visit, aggregate the prediction results for all visitors, and select locations that are likely to become hotspots in the future. Tour guiding resources related to these hotspots may be pushed to the edge computing layer in advance to reduce the time delay of subsequent visits and enhance the user experience.

Hereinafter, more details of an example implementation according to the present disclosure will be described with reference to FIG. 4. FIG. 4 schematically illustrates a flow chart of method 400 for scheduling tour guiding resources in a mobile network according to an example implementation of the present disclosure. As shown, at block 410, a plurality of historical routes of movement of a plurality of historical users in geographic area 210 may be acquired, where a historical route in the plurality of historical routes may include at least a portion of a plurality of locations in geographic area 210.

For example, one historical route may include: the Meridian Gate—the Hall of Supreme Harmony—the Hall of Central Harmony—the Hall of Preserving Harmony—the Imperial Garden; and another historical route may include: the Meridian Gate—the Hall of Supreme Harmony—the Hall of Central Harmony—the Hall of Preserving Harmony—the Palace of Heavenly Purity—the Hall of Mental Cultivation. Here, historical routes of historical users in different seasons, different dates, different time periods, and different weather conditions may be collected, so that historical data set 310 can reflect the general touring habits of a large number of users. It will be understood that historical users here may include users who use the tour guiding service and may also include general users who do not use the tour guiding service.

At block 420, based on the plurality of historical routes and a plurality of current positions of a plurality of users in geographic area 210, a set of predicted locations among the plurality of locations that the plurality of users will visit in the future may be determined respectively. Here, the plurality of users use a tour guiding service associated with the plurality of locations that is provided by the mobile network. According to an example implementation of the present disclosure, the current position of each user may be collected in real time directly from the mobile terminal carried by the user. Alternatively and/or additionally, current positions of the users may be collected at a predetermined time interval. For example, the user positions may be collected every 5 minutes or at other time intervals.

It will be understood that the future time here may be a predetermined time point after the current time point, e.g., 10 minutes later, 15 minutes later, or other future time points. It may be possible to determine, according to the user touring habits extracted from the plurality of historical routes, which location each of the plurality of users will visit in the future. For example, the next destination of each user may be determined based on the Bayesian method. For ease of description, the terms shown in Table 1 below are first introduced.

Hereinafter, the equation used to determine the user's position in the future will be constructed based on the symbols shown in Table 1 above. It will be understood that the symbols used in the equations below have the same meaning as those shown in Table 1 and thus will not be repeated at each equation. According to an example implementation of the present disclosure, in order to determine a set of predicted locations, a conditional probability that the plurality of historical users visit at least one other location prior to visiting a given location in the plurality of locations may be determined based on the plurality of historical routes. Further, the set of predicted locations that the plurality of users will visit in the future may be determined based on the conditional probability. Specifically, it is possible to determine statistically, based on the historical routes, which other location a historical user prefers to visit after visiting a given location.

According to an example implementation of the present disclosure, for each location c_k in the plurality of locations, the priori probability that a historical user visits the location may be determined. For example, the priori probability P(c_k) that a historical user visits location c_k may be determined based on Equation 1:

$\begin{array}{cc}P\left(c_k\right)=\frac{n_{c_k}}{n}& \mathrm{Equation}1\end{array}$

That is, the priori probability P(c_k) may be determined based on the ratio of the number n_ck of historical users who visited location c_k to the number of all historical users. Assuming that location c_k represents the Imperial Garden, the historical data set involves 10,000 historical users, and 1,000 of them visited the Imperial Garden, then the priori probability associated with the Imperial Garden that is determined based on the historical data set is 1,000/10,000=0.1. All locations may be processed based on Equation 1. In this way, the priori probabilities associated with the locations such as the Meridian Gate, the Hall of Supreme Harmony, the Hall of Central Harmony, the Hall of Preserving Harmony, the Palace of Heavenly Purity, and the Hall of Mental Cultivation may be determined respectively.

According to an example implementation of the present disclosure, in order to determine the conditional probability, a first number of users of users among the plurality of users who visited the given location may be determined. Further, for other locations in the plurality of locations different from the given location, a second number of users among the plurality of users who visited the other locations prior to visiting the given location may be determined. A conditional probability for the other locations is determined based on the first number of users and the second number of users. It will be understood that the conditional probability here is a conditional probability P(x|c_k) determined based on the historical data set. Specifically, the conditional probability P(x|c_k) may be determined based on Equation 2 as follows:

$\begin{array}{cc}P\left(x|c_k\right)=\frac{n_{x,c_k}}{n_{c_k}}& \mathrm{Equation}2\end{array}$

Equation 2 indicates that the conditional probability P(x|c_k) may be determined based on the ratio of the number of historical users who visited location x prior to visiting location c_k to the number of historical users who visited location c_k. With the example implementation of the present disclosure, the touring habits of the historical users in the historical data set may be counted, and the touring habits may then be used to predict the next destination of each current user that is currently in the geographic area.

According to an example implementation of the present disclosure, the conditional probability P(x|c_k) determined in Equation 2 may further be used to predict the next destination of each current user respectively. Specifically, for a given user among the plurality of users, a predicted location that the given user will visit in the future may be determined based on the conditional probability. In other words, the location where the given user will be located in the future is determined based on the location x where the given user is currently located and the conditional probability P(x|c_k). Specifically, a visiting probability P(c_k|x) that the given user will visit each of the other locations in the plurality of locations in the future may be determined respectively based on the conditional probability:

$\begin{array}{cc}P\left(c_k|x\right)=\frac{P\left(x|c_k\right)P\left(c_k\right)}{P\left(x\right)}& \mathrm{Equation}3\end{array}$

Here, the specific value of P(x|c_k) may be determined based on Equation 2. It will be understood that x here is the location where the given user is located. For example, the specific value of x may be determined based on the location closest to the given user. c_k may be any one of the plurality of locations. In this way, the visiting probabilities that the given user visits various locations may be determined one by one. Assuming that the geographic area includes K locations, then K visiting probabilities may be determined.

Further, the predicted location that the given user will visit in the future may be determined based on a comparison of the determined K visiting probabilities. According to an example implementation of the present disclosure, among the visiting probabilities associated with the other locations, the location associated with the maximum probability may be identified as the predicted location. Specifically, the location with the maximum visiting probability may be selected based on Equation 4 as follows:

$\begin{array}{cc}{R}_i=\underset{k=1,\dots ,K}{\max }P\left(c_k|x\right)=\underset{k=1,\dots ,K}{\max }\frac{P\left(x|c_k\right)P\left(c_k\right)}{P\left(x\right)}& \mathrm{Equation}4\end{array}$

where R_i denotes the prediction result for user i, i.e., which location the user i will visit next. Hereinafter, more details of the visiting probability that a user goes to each of the other locations will be described with reference to FIG. 5. FIG. 5 schematically illustrates block diagram 500 for determining a location that a given user will arrive at in the future according to an example implementation of the present disclosure. As shown in FIG. 5, for user 510, the probabilities that user 510 goes to other locations may be determined respectively based on the equation described above. Assuming that user 510 is located at given location 520, then the probabilities (as shown by respective arrows in the figure) that user 510 goes to locations 0, 2, 1, 5, and 4 may be determined respectively at this point. As shown in FIG. 5, the probability that user 510 goes to location 4 in the future, which is 0.6, is greater than the probabilities that the user goes to the other locations, and thus location 4 may be used as the next destination of user 510.

It will be understood that the above description only uses user 510 in FIG. 5 as a specific example of a given user to describe how to determine the user's next destination. If there are also a plurality of other users 512 in geographic area 210, similar processing may be performed for each of the plurality of other users 512. Further, the following may be determined based on Equation 5: Whether the prediction result for user i is equal to c_k, i.e., whether the user will go to location c_k next.

$\begin{array}{cc}{R}_{c_k,i}=\{\begin{array}{cc}0& R_i\ne c_k,k=1,\dots ,K\\ 1& R_i=c_k,k=1,\dots ,K\end{array}& \mathrm{Equation}5\end{array}$

According to an example implementation of the present disclosure, the method described above may be performed respectively for each user i among the plurality of current users, and in this way, the predicted location that each user will visit in the future can be accurately estimated based on historical experience. FIG. 6 schematically illustrates block diagram 600 of the distribution of a plurality of users in the future according to an example implementation of the present disclosure. As shown in FIG. 6, a plurality of users in a geographic area will exhibit different distributions at future time points, e.g., user 610 will be located at location 0 in the future, a plurality of users 614 will be located at location 5 in the future, a plurality of users 612 will go to location 4 in the future, etc. Then, further processing may be performed based on a set of predicted locations that the plurality of users will visit.

Returning to FIG. 4, more information about the selection of popular locations based on the predicted locations will be described. At block 430 of FIG. 4, a set of popular locations may be selected from the set of predicted locations based on the number of users among the plurality of users who will visit each predicted location in the set of predicted locations. In this step, the set of predicted locations that all users may arrive at may be generated based on the predicted location of each user. Specifically, the number of users who may visit location c_k at a future time may be determined based on Equation 6 as follows.N_ck=Σ_i=1^NR_ck,i (k=1, . . . ,K)  Equation 6

With Equation 6, it is possible to determine, based on whether user i will visit location c_k in the future, how many people will visit location c_k in the future. Further, popular locations may be selected based on the number of users who will visit each location in the future. In other words, a location corresponding to the greatest number of users is selected as a popular location. According to an example implementation of the present disclosure, the processing shown in Equation 6 may be performed for each location included in the geographic area to predict how many users will come to each location.

It will be understood that the forgoing uses only Equations 1 to 6 to describe examples of predicting, based on the historical data set, the location to which a user is likely to go. According to an example implementation of the present disclosure, a variety of other factors may be further taken into consideration in predicting the next destination of the user. Typically, users are more inclined to tour famous scenic spots, and thus high weights may be assigned to famous scenic spots. For another example, the next destination of a user may be further determined based on factors related to the user's current tour, such as the time of day, the season, and the weather. It may be considered that the user prefers to tour outdoor scenic spots during lighter hours in a day, and indoor scenic spots during darker hours, such as in the evening. For another example, the next destination may be predicted based on the tour routes that the user has already taken. For another example, the next destination may be further determined based on the distance between the user's current location and surrounding locations, and so on.

According to an example implementation of the present disclosure, in order to select the set of popular locations from the set of predicted locations, the set of predicted locations may be ranked by the number of users who will visit each predicted location in the set of predicted locations. Assuming that the current number of users is 5,000 and that the predicted number for each location is as shown in Table 2 below:

TABLE 2
Predicted number
	No.	Location	Predicted number
	1	the Meridian Gate	250
	2	the Hall of Supreme Harmony	500
	3	the Hall of Central Harmony	600
	4	the Hall of Preserving Harmony	350
	. . .	. . .	. . .
	. . .	the Imperial Garden	150
	. . .	. . .	. . .
	K	. . .	. . .

The predicted numbers as shown in Table 2 may be ranked in a descending order to obtain the ranking shown in Table 3.

TABLE 3
List of locations ranked by numbers from large to small
	Ranking	Location	Predicted number
	1	the Hall of Central Harmony	600
	2	the Hall of Supreme Harmony	500
	3	the Hall of Preserving Harmony	350
	4	the Meridian Gate	250
	. . .	. . .	. . .
	. . .	the Imperial Garden	150
	. . .	. . .	. . .
	K	. . .	. . .

According to an example implementation of the present disclosure, the top-ranked (e.g., top three or other number) locations may be selected from Table 3. As shown in Table 3, “the Hall of Central Harmony,” “the Hall of Supreme Harmony,” and “the Hall of Preserving Harmony” may be selected, and the tour guiding resources associated with these locations may be preferentially loaded into the edge computing layer.

At block 440, tour guiding resources associated with the set of popular locations are scheduled, wherein the tour guiding resources are stored at one or more of a core network layer and an edge computing layer in the mobile network. Specifically, if it is determined that the tour guiding resources are not stored at the edge computing layer, a request is sent to the core network for loading the tour guiding resources from the core network to the edge computing layer. If it is determined that the tour guiding resources have been stored in the edge computing layer, there is no need to perform additional loading operations. With the example implementation of the present disclosure, before a large number of users arrive at a popular location, tour guiding resources may be pre-loaded to the edge computing layer that is closer to mobile terminals carried by the users. In this way, the tour guiding resources that the users expect to view are already located in the edge computing layer, and thus the users do not have to wait for the transmission of the tour guiding resources from the remote core network layer.

According to an example implementation of the present disclosure, the edge computing layer may provide, in response to a fetch request from a mobile terminal of a user among the plurality of users, a portion of the tour guiding resources associated with a current location of the mobile terminal from the edge computing layer to the mobile terminal. Assuming that a user is on the way to the Hall of Supreme Harmony. When the mobile terminal approaches the Hall of Supreme Harmony, the mobile terminal may automatically send a request to a server device in the edge computing layer to fetch the tour guiding resources associated with the Hall of Supreme Harmony. At this time, a resource scheduler in the edge computing layer may transmit the tour guiding resources to the mobile terminal.

According to an example implementation of the present disclosure, the tour guiding resources include data of at least any of the following services associated with the set of popular locations: a streaming media service, a virtual reality service, an augmented reality service, and a mixed reality service. With the example implementation of the present disclosure, data may be provided to the user in a variety of formats via a tour guiding application, thereby providing the user with a comprehensive understanding of information about various aspects of each location. For example, streaming media data, including audio/video, may be provided to the user to introduce the architectural style, historical story, etc. about the location. Three-dimensional virtual reality animations of historical changes of buildings at each location may be provided to the user, so that the user can understand historical features of each location.

In the tour guiding application scenario, augmented reality services may be provided when the mobile network supports 5G schemes with high data rates and low latency computing. Augmented reality is a technology that computes the position and angle of a collected image in real time and provides corresponding multimedia information. The goal of this technology is to display a virtual world at a mobile terminal and allow interaction with the real world. By overlaying additional information on the surrounding environment, augmented displays can merge the real world with the virtual world. For example, when a user uses a camera device of the mobile terminal to focus on the Hall of Supreme Harmony, parameters such as the length, width, and height of each part may be superimposed and displayed on the image of the Hall of Supreme Harmony, and so on. Further, mixed reality services may be provided to the user. For another example, when a user visits a museum or gallery, augmented reality services can enhance the user's experience and bring better visual effects. As the user approaches each exhibit, the mobile terminal can present information related to the exhibit.

Hereinafter, a process for scheduling tour guiding resources according to an example implementation of the present disclosure will be described with reference to FIG. 7. FIG. 7 schematically illustrates block diagram 700 of interaction between a plurality of devices according to an example implementation of the present disclosure. In the context of the present disclosure, method 400 described above may be performed by resource scheduler 712. As shown in FIG. 7, a user may use tour guiding application 710 to receive tour guiding resources while touring in the Forbidden City. Resource scheduler 712 may, for example, run in the edge computing layer and periodically execute method 400 described above. When a change in the distribution of users within a geographic area is detected, it can be determined 720 whether the edge computing layer includes tour guiding resources for popular areas. If the determination result is “no,” resource scheduler 712 may request 722 related tour guiding resources from core network manager 714.

Upon receiving the request from resource scheduler 712, core network manager 714 may send 724 the tour guiding resources to a specified position in the edge computing layer. At this point, the tour guiding resources are pre-loaded into the edge computing layer for invocation by tour guiding application 710.
