The software system of the above electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application takes a layered Android system as an example to illustrate the software structure of the electronic device 100.

FIG. 2 is a block diagram of the software structure of the electronic device 100 according to an embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Communication between layers through software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

The application layer can include a series of applications.

As shown in Fig. 2, application programs may include applications (application, APP) such as call, contact, camera, gallery, calendar, map, navigation, Bluetooth, music, video, short message, etc. Among them, the call APP (also called dialing APP or phone APP) and contact APP (also called address book APP or phone book APP) can be preset when the mobile phone leaves the factory, or can be used in the application market. Third-party applications for calling.

The application framework layer provides application programming interfaces (application programming interface, API) and programming frameworks for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer may include phone service and contact service.

Among them, the call service can be used to provide the call function of the electronic device 100. For example, the call service can manage the call status of the call APP (for example, initiate, connect, hang up, etc.). If it is detected that the user uses the call APP to make an incoming or outgoing call with a certain phone number, the call service can monitor the call status of this call. If a dialing failure event is detected, the call service can also obtain the reason for the dialing failure sent by the base station, such as network failure, rejection by the other party, failure to connect over time, or busy tone of the other party.

Each time it is detected that the user uses the call APP to make or receive a call, as shown in Figure 3, the call service can record the basic information of the call record in each field of the call record table 301, for example, the ID of the call record (ID The value can increase with the number of call records), the contact (or phone number) of the call, the incoming/outgoing time, date, time, and duration of the call. In the embodiment of the present application, the call service may also record the location information of the user during each call in the call record table 301, for example, the latitude and longitude coordinates of the electronic device 100. In this way, the electronic device 100 can query the geographic location where the user is in each call with each contact through the call record table 301.

The above contact service can be used to manage the contact list in the contact APP, such as creating new contacts in the contact list, deleting contacts, or modifying various information in the contacts. After the contact APP detects the user's operation to create a contact, it can call the contact service to save one or more information such as the name, phone number, and address of the contact entered by the user. Furthermore, the contact service can create a new contact in the contact database (contact.db), and add one or more of the obtained information to the newly created contact.

In some embodiments of the present application, as shown in FIG. 2, the application framework layer may also include a clustering algorithm module. Among them, the clustering algorithm module can periodically obtain the call record of the user in the most recent period from the call service (for example, the call record table 301 mentioned above). Furthermore, the clustering algorithm module can perform geographic cluster analysis on the location information recorded in each call record in the call record table 301 to obtain a clustering result based on geographic location. For example, as shown in Figure 4, through geographic clustering analysis, the clustering algorithm module can divide the N (N>1) location information in the call log table 301 into one or more geographic clusters (for example, geographic clusters 401 and 401). Geographic cluster 402). Each geographic cluster covers a certain area of geographic area, and each geographic cluster can also be called a geographic area. The similarity of location information in the same geographic cluster is as large as possible, and the difference of location information that is not in the same geographic cluster is also as large as possible. For example, each geographic location in the geographic cluster 401 belongs to the Xi'an area, and each geographic location in the geographic cluster 402 belongs to the Beijing area. Among them, each geographic location (ie, location information) in FIG. 4 corresponds to a call record in the call record table 301.

Then, when it is detected that the user opens the call APP (or contact APP), indicating that the user has the intention to make a call at this time, the call service (or contact service) can obtain the location information of the current user (for example, location A), Furthermore, the clustering algorithm module is requested to determine one or more contacts associated with location A according to the above-mentioned geographic location-based clustering result. The one or more contacts are contacts that the user has contacted in the vicinity of location A. Furthermore, the electronic device may display one or more contacts that can be determined by the clustering algorithm module as a recommendation result in the call APP (or contact APP).

Of course, the application framework layer can also include window managers, content providers, view systems, resource managers, notification managers, etc.

Among them, the window manager is used to manage window programs. The window manager can obtain the size of the display, determine whether there is a status bar, lock the screen, take a screenshot, etc. The content provider is used to store and retrieve data and make these data accessible to applications. The data may include video, image, audio, phone calls made and received, browsing history and bookmarks, phone book, etc. The view system includes visual controls, such as controls that display text and controls that display pictures. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface that includes a short message notification icon may include a view that displays text and a view that displays pictures. The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc. The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and it can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears in the status bar at the top of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, text messages are prompted in the status bar, prompt sounds, electronic devices vibrate, and indicator lights flash.

Android Runtime includes core libraries and virtual machines. Android runtime is responsible for the scheduling and management of the Android system.

In the following, a mobile phone is used as an example of an electronic device, and a method for recommending a contact provided by an embodiment of the present application is described in detail with reference to the accompanying drawings.

As shown in FIG. 5, a method for recommending contacts provided by an embodiment of the present application includes the following steps S501-S505.

S501. In response to the user's operation of opening the call APP, the mobile phone obtains the user's current location information.

Generally, when using a mobile phone to call a contact, a user needs to open the call APP in the mobile phone to find the contact. When the user's operation to open the call APP is detected, the mobile phone can obtain the location information of the current user.

For example, the mobile phone can obtain the latitude and longitude coordinates of the current mobile phone through the GPS module, and the latitude and longitude coordinates are the location information of the current user. For another example, if the mobile phone is connected to the Wi-Fi network of a certain access point (AP), the IP address (or MAC address) of the AP is generally fixed and the location of the AP is away from the location of the mobile phone. It is not very far away. Therefore, the mobile phone can query the location information of the AP by obtaining the IP address (or MAC address) of the AP, and further, the mobile phone can use the location information of the AP as the location information of the current user. Similarly, the mobile phone can also determine the current user's location information through the IP address (or MAC address) of the current Bluetooth connection. Alternatively, the mobile phone may also request the base station to use the distance between the base station and the mobile phone to calculate the location of the mobile phone, that is, the location information of the current user, which is not limited in this embodiment of the application.

Exemplarily, after detecting the operation of the user to open the call APP, the mobile phone can obtain the user's current location information. As shown in FIG. 6, the mobile phone can also display the call list interface 601 of the call APP. The call list interface 601 includes one or more call records. Among them, the basic information of each call record is recorded by the mobile phone in the call record table 301 shown in FIG. 3.

Of course, the mobile phone can update the aforementioned call log table 301 regularly. For example, a maximum of 100 call records can be stored in the call record table 301 in advance. Then, when the mobile phone generates the user's 101st call record, the basic information of the call record with the earliest record time in the call record table 301 can be deleted. For another example, the call record table 301 can be set to record the call records of the user in the last month. Then, when the incoming or outgoing time of the call record in the call record table 301 exceeds one month, the mobile phone can delete the basic information of the call record.

In addition, each call record in the call list interface 601 can also be used as a shortcut for calling a contact. The user can select a corresponding call record in the call list interface 601 to perform a dialing operation. As still shown in FIG. 6, if the mobile phone detects that the user clicks on the call record 1 in the call list interface 601, the mobile phone can automatically call the contact Mike according to Mike's phone number recorded in the call record 1.

In some embodiments, the mobile phone can also obtain the current location information of the user in response to other operations of the user. For example, the mobile phone may display the above-mentioned call list interface 601 after detecting that the user opens the call APP. Furthermore, if it is detected that the user has performed a preset gesture in the call list interface 601, such as a pressing operation, a tapping operation, or a sliding operation with a preset sliding track, the mobile phone can respond to the gesture to obtain the user's current location information. The application embodiment does not impose any restriction on this.

S502. The mobile phone determines X contacts associated with the current location information based on a preset clustering model, and X≥1.

Wherein, the above X contacts are: one or more contacts in the call record (for example, the call record table 301) that the user has contacted near the location information.

Exemplarily, a geographic clustering model can be set in the mobile phone in advance, such as K-Means (K-means clustering method) clustering model, DBSCAN (density-based Spatial clustering of applications with noise, density-based The clustering algorithm model, the BIRCH (balanced iterative reducing and clustering using hierarchies, the balanced iteration protocol and clustering using the hierarchical method) model, the STING algorithm model, etc., are not limited in the embodiments of this application.

As shown in FIG. 7, the mobile phone can input the location information recorded in each call record in the call record table 301 into the geographic clustering model. The location information recorded in multiple call logs may be the same or different. Taking latitude and longitude coordinates as an example of location information, the geographic clustering model can perform geographic clustering analysis on all latitude and longitude coordinates in the call log table 301 through a preset clustering algorithm, and divide multiple latitude and longitude coordinates with similar locations into one geographic cluster . As still shown in FIG. 7, the mobile phone can divide the multiple latitude and longitude coordinates recorded in the call log table 301 into three geographic clusters, that is, geographic cluster 701-geographic cluster 703 through cluster analysis. Among them, one latitude and longitude coordinate in each geographic cluster corresponds to one or more contacts. Taking the longitude and latitude coordinates of point A in the geographic cluster 701 as an example, if the user used to call contacts Sam and Jack at point A, then point A corresponds to both contact Sam and contact Jack.

The mobile phone can calculate the contact list corresponding to each geographic cluster according to information such as the number of calls and the duration of the call between the user and each contact in the call record table 301. Taking geographic cluster 701 as an example, geographic cluster 701 includes 4 latitude and longitude coordinates. Among them, the user has talked with contact Sam twice at latitude and longitude coordinates A, the user has talked with contact Sam once at latitude and longitude coordinates B, and the user has talked with contact Jack twice at latitude and longitude coordinates. The coordinate point C has a call with the contact Amy once. Then, in the descending order of the number of calls, the mobile phone can determine that the contact list A corresponding to the geographic cluster 701 sequentially includes: contact Sam, contact Jack, and contact Amy.

Then, in step S502, after the mobile phone obtains the current location information of the user this time, taking the location information as the longitude and latitude coordinates as an example, the call service in the mobile phone can send the longitude and latitude coordinates of the Z point to the geographic clustering model. Request the geographic clustering model to determine the geographic cluster to which point Z belongs. For example, as shown in FIG. 8, if the latitude and longitude coordinate Z point belongs to the geographic cluster 701, the mobile phone can determine that the contact associated with the current location information (ie Z point) is: the contact list A in the contact list A corresponding to the geographic cluster 701 One or more contacts. Alternatively, the mobile phone may determine the top X contacts in the contact list A as contacts associated with the current location information (ie, point Z). That is to say, each time the user makes a call, the mobile phone can determine the X contacts that the user has frequently contacted near the location based on the user's location at this time. These X contacts are likely to be the contacts the user wants to call this time. people.

S503. The mobile phone displays the shortcuts of the above X contacts in the call APP.

Exemplarily, after the mobile phone determines X contacts associated with the user's current location information, as shown in FIG. 9, the mobile phone may display a recommendation notification 901 on the call list interface 601. The recommendation notification 901 may include the shortcuts of the X contacts determined by the mobile phone in step S502. Since the contacts in the recommendation notification 901 are all contacts that the user frequently contacts at the current location, the user can quickly select the phone number of the contact who needs to call this time through the recommendation notification 901, thereby simplifying the operation of the user and the contact to make calls The process improves the efficiency and user experience for users to find contacts.

Or, after the mobile phone determines X contacts associated with the user's current location information, as shown in FIG. 10, the mobile phone can rearrange the call records in the call list interface 601, and display the recent call records 1001 of the above X contacts in The top of the call list is convenient for users to find and choose. In addition, as shown in FIG. 10, the mobile phone can also mark the call record 1001 in the call list interface 601 as the recommended reason: friends contacted nearby, presenting a more intelligent call operation experience to the user.

Or, as shown in (a) in FIG. 11, the mobile phone can also set a smart recommendation menu 1101 in the call APP. If it is detected that the user opens the smart recommendation menu 1101, as shown in Figure 11 (b), the mobile phone can display a smart recommendation interface 1102, and the smart recommendation interface 1102 includes X contacts determined by the mobile phone for the user in step S502 Shortcuts. Taking the user's current location as Bantian as an example, the mobile phone can prompt the user in the smart recommendation interface 1102 with the contact list 1103 that the user has contacted near Bantian. For example, as shown in (b) of FIG. 11, the mobile phone can display the contacts that the user has contacted near Bantian in the order of the number of calls, and display the number of calls each contact has with the user. The user can select the relevant contact in the contact list 1103 to quickly complete the dialing operation.

Of course, mobile phones can also use Preference Learning (Preference Learning) sorting algorithm, LR (Logistic Regression) sorting algorithm, GBDT (Gradient Boosting Decision Tree, gradient boosting tree) sorting algorithm or MFU (Most Frequently Used, most commonly used) Sorting algorithms such as sorting algorithm sort the contacts whose mobile phone determines X in step S502. For example, the mobile phone can use the GBDT sorting algorithm to determine the call status in Figure 11(b) based on the call frequency, call duration, whether the headset is plugged in and out of the call, and the battery level of the mobile phone recorded in the related call records in the user call log table 301. The order of people Sam, Jack, Amy, Peter and Sara is not limited in the embodiment of the application.

In some other embodiments of the present application, the mobile phone may also use time as the granularity to count the contact lists corresponding to different time periods. As shown in Figure 12, the mobile phone can be divided into multiple time periods in advance. For example, 9 o'clock to 11 o'clock is regarded as the time zone 1201, 11 o'clock to 14 o'clock is regarded as the time zone 1202, and so on. Furthermore, the mobile phone can determine one or more call records belonging to each time period according to the outgoing time or incoming time of each call record in the call record table 301. As shown in FIG. 12, the mobile phone can determine through statistics that the time period 1201 includes 15 call records, and the time period 1202 includes 10 call records. Because each call record corresponds to a contact. Therefore, the mobile phone can count the contact list corresponding to each time cluster.

In addition, the mobile phone can dynamically adjust the time periods divided above. For example, since the call record in the call record table 301 is updated in real time, the mobile phone can periodically re-divide the time period according to the outgoing time or incoming time of the call record in the call record table 301. For example, when it is detected that the user’s call frequency is high during the time period from 9:00 to 10:30, the mobile phone can modify the time interval of the above time period 1201 from 9:00 to 11 to 9:00 to 10:30 Minute.

Still taking the time period 1201 as an example, the time period 1201 includes 15 call records. Among these 15 call records, 7 are call records with the contact Sam, 5 are call records with the contact Jack, and 3 Bar is the call log with the contact Tom. Then, according to the order of the number of calls, the mobile phone can determine that the contact list B corresponding to the time period 1201 includes: contact Sam, contact Jack, and contact Tom.

Then, after detecting the operation of the user to open the call APP, the mobile phone can obtain current time information in addition to the location information of the current user, for example, the current time is 9:48. Furthermore, the mobile phone can determine, based on the current time, that the call that the user needs to make this time belongs to the aforementioned time period 1201. At the same time, referring to the related description of step S502, based on the clustering result of the geographic clustering model, the mobile phone can determine that the call that the user needs to make this time belongs to the geographic cluster 701. The contact list A corresponding to the geographic cluster 701 sequentially includes: contact Sam, contact Jack, and contact Amy. The contact list B corresponding to the time period 1201 sequentially includes: contact Sam, contact Jack, and contact Tom.

It can be seen that the overlapping contacts in the contact list A and the contact list B are: Sam and Jack, indicating that the user often interacts with Sam in the time period from 9 am to 11 am at the current location (for example, point Z). Talk to Jack. Then, the mobile phone can determine the contacts Sam and Jack as the X contacts who currently need to be recommended to the user. As shown in (a) in Figure 13, the mobile phone can display shortcuts for contacts Sam and Jack in the smart recommendation interface 1301 of the call APP. At the same time, the mobile phone can display the recommendation reason 1302 of the contact recommended this time in the smart recommendation interface 1301: the recommendation result based on the location of the user and the current time is convenient for the user to quickly find the desired contact to make a call after opening the call APP. Or, as shown in (b) of FIG. 13, the mobile phone may display the contacts in the contact list A and the contact list B as the recommendation results in the smart recommendation interface 1301. In addition, the mobile phone can display the overlapping contacts in the contact list A and the contact list B (namely contacts Sam and Jack) on the top of the smart recommendation interface 1301, which is convenient for the user to quickly find the desired contact after opening the call APP Make a call.

Or, the mobile phone can select the top X1 contacts in the contact list A, and select the top X2 contacts in the contact list B, and then the mobile phone can select the X1 contacts And X2 contacts are determined as contacts that need to be recommended to the user this time. As shown in FIG. 14, the mobile phone can display the recommendation list 1402 and the recommendation list 1403 in the smart recommendation interface 1401 of the call APP. Wherein, the recommendation list 1402 is based on the user's current location and recommends for the user one or more contacts who frequently call at the location. The recommendation list 1403 is based on the one or more contacts recommended for the user who frequently talk in the current time period based on the current time. The contacts in the recommendation list 1402 and the recommendation list 1403 may be the same or different. Of course, the mobile phone can also integrate the contacts in the recommendation list 1402 and the recommendation list 1403 into one recommendation list and display it in the smart recommendation interface 1401, which is not limited in this application.

S504: If it is detected that the user selects the shortcut of the first contact, the mobile phone calls the phone number of the first contact.

Exemplarily, as shown in (a) of FIG. 15, if it is detected that the user selects a shortcut 1501 of a contact (for example, Sam) recommended by the mobile phone for the user in step S503, as shown in (b) of FIG. 15 As shown, the mobile phone can display a call interface 1502 for calling contact Sam, and perform a dialing operation according to the phone number of contact Sam.

It can be seen that after the user opens the call APP, the mobile phone can intelligently recommend contacts that the user frequently contacts near the location based on the user's current location and other information. In this way, the user can quickly find the contact who needs to dial this time according to the contact recommended by the mobile phone before dialing, without manually searching for the corresponding contact in the lengthy call log list, thus simplifying the operation process when the user is talking with the contact , Improve the user experience.

It should be noted that in the above embodiment, the user uses the call APP to find a contact to make a call. It is understandable that if it is detected that the user opens the contact APP, the mobile phone can also perform the above steps S501-S504 in the contact The APP recommends a list of contacts frequently contacted at the current location to the user, so that the user can quickly find the contact who needs to dial this time. The embodiment of the application does not impose any restriction on this.

S505. The mobile phone updates the clustering result in the clustering model.

In step S505, the mobile phone may periodically update the clustering results of the geographic clustering model. It should be noted that the embodiment of the present application does not impose any restriction on the execution sequence between step S505 and the foregoing steps S501-S504.

Exemplarily, it can be set to automatically trigger the mobile phone to update the clustering result of the geographic clustering model after detecting every new N (N≥1) call records in the call record table 301. For another example, the mobile phone can set an update cycle (for example, daily, weekly, or monthly), and the mobile phone can automatically update the clustering results of the geographic clustering model according to the update cycle. For example, when the mobile phone updates the clustering results of the geographic clustering model every day, it can choose to update at night or during idle time such as when the mobile phone is charging, so as to avoid the update process of the clustering model occupying too much mobile phone resources and causing users to be unable to use the mobile phone normally.

Taking the example of updating the clustering results of the above geographic clustering model every week, at each update, as shown in FIG. 16, the mobile phone can obtain the current call record table 1601 from the call service. Each call record in the call record table 1601 stores corresponding location information. Furthermore, the mobile phone can input the location information in each call record into the geographic clustering model for geographic cluster analysis, and divide multiple geographic locations with similar location information into a geographic cluster. As shown in FIG. 16, compared with the clustering result shown in FIG. 7, in the updated geographic clustering result, in addition to geographic cluster 701 to geographic cluster 703, geographic cluster 1602 is newly added. The geographic cluster 1602 includes multiple geographic locations, indicating that the user frequently talks with contacts within the coverage area of the geographic cluster 1602 recently. At the same time, the mobile phone can also update the coverage size and location of each geographic cluster according to each call record in the latest call record table. The contact list corresponding to each geographic cluster is updated accordingly. Subsequently, after detecting the operation of the user to open the call APP or the contact APP, the mobile phone can determine the contact associated with the current user location based on the latest geographical clustering result, thereby improving the accuracy of the contact recommended by the mobile phone to the user.
