DETAILED EMBODIMENTS

The application is further described in detail below with reference to the accompanying drawings.

In a typical configuration of the present application, a terminal, a device of a service network and a trusted party all include one or more processors (CPUs), an input/output interface, a network interface and a memory.

The memory may include a non-permanent memory, a random access memory (RAM) and/or a non-volatile memory and the like in a computer-readable medium, such as a read-only memory (ROM) or a flash memory (flash RAM)). A memory is an example of a computer-readable medium.

A computer-readable medium comprises permanent and non-permanent, movable and non-movable media and may implement information storage by means of any method or technology. Information may be computer-readable instructions, data structures, program modules or other data. The examples of a computer storage medium include but are not limited to a phase change memory (PRAM), a static random access memory (SRAM), a dynamic random access memory (DRAM), other types of random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a flash memory or other memory technologies, compact disk read-only memory (CD-ROM), a digital versatile disc (DVD) or other optical storages, a magnetic cassette tape, and magnetic tape and magnetic disk storage or other magnetic storage devices or any other non-transmission media, which can be used to store information that can be accessed by a computing device. According to the definition herein, the computer-readable medium does not include a non-transitory computer-readable medium, such as a modulated data signal and a carrier.

FIG. 1 shows a schematic flowchart of a method for friend recommendation at a network device provided according to an aspect of the present application. The method comprises steps S11 to S13. At step S11, user information of a first user and second user indication information are obtained. At step S12, a second user is determined according to the second user indication information. At step S13, the user information of the first user is sent to a recommended user list of the second user. Here, the first user and the second user are relative to each other. A user whose contact list contains other user(s) may be identified as a first user, and it is determined whether the other user(s) contained in the contact list can be identified as the second user according to indication information of the other user(s) contained in the contact list. For example, if contacts in a contact list of a user A contain a user B, user A is a first user, and it is determined whether user B is a second user according to indication information of user B. Then, when user B is the second user, user information of user A is recommended to user B, and thus the user information of user A is contained in a recommended user list of user B, which realizes reverse friend recommendation according to the contact list. The user information comprises information for identifying a user identity, such as a user name, a mobile phone number or the like. It should be noted that the network device described in the foregoing embodiment may be a server, or multiple servers connected through a local area network or multiple servers connected through the Internet, or a cloud composed of multiple servers. Here, the cloud is composed of a massive number of computers or network servers based on Cloud Computing, and cloud computing is a type of distributed computing, which is a super virtual computer composed of a group of loosely coupled computer sets.

In an embodiment of the present application, when the second user indication information comprises second user identification information. The network device may obtain identification information of a second user in the contact list which has been filtered by a first user equipment where a first user is located, and determine the second user according to the second user identification information. Here, in specific, filtering contacts in the contact list of the first user and determining the second user identification information may be determined by: comparing, by the first user equipment, information on the contact list of the first user with information on a friend list of the first user and determining identification information of a contact not in the friend list but in the contact list as the second user identification information. Comparison is conducted at the first user equipment at first, and then the network device receives the identification information of the second user determined by the comparison, and to send recommendation information for recommending a friend desired by the second user to the second user who has been determined according to the identification information, which can avoid distributing friend recommendation messages arbitrarily and can reduce the amount of data required by data transmission when reporting to the network device, saving network traffic, and thus reducing burden on the network device.

In addition, the network device not only can obtain the identification information of the second user which has been filtered by the first user equipment where the first user is located at first, to determine the second user, but also can obtain information on a contact list sent by the first user, to filter and determine the second user. When the second user indication information comprises information on a contact list of the first user, the second user may be determined according to the information on the contact list of the first user. In specific, information on a friend list of the first user is obtained, the information on the contact list of the first user is compared with the information on the friend list of the first user, and a contact not in the friend list but in the contact list is identified as the second user. Here, when each of contacts in the contact list of the first user is identified as the second user, it will cause invalid recommendation and a waste of system resources. For example, if user B and user C contained in the contact list of the first user (user A) are already existing in a friend list of user A, there is no need to recommend user information of user A to user B and user C. Therefore, the contacts in the contact list of user A may be compared with friends in the friend list of user A at first. When some user(s) are only existing in the contact list of user A but not existing in the friend list of user A, such user(s) may be identified as the second user(s), and to recommend user A to the contacts in the contact list who have not established friend relationship with user A.

In an embodiment of the present application, at step S12, information on a friend list of the second user is obtained, and it is determined whether the first user is existing in the friend list of the second user. If not, the user information of the first user is sent to a recommended user list of the second user. Here, when a contact list of the first user contains contact information of the second user, and thus the first user is recommended to the second user, the first user may already be existing in a friend list of the second user. At this time, there is no need to recommend the first user to the second user repeatedly. Therefore, it may be determined whether the first user is already existing in the friend list according to the information on the friend list of the second user. If not, then the user information of the first user is sent to a recommended user list of the second user, and to achieve reverse friend recommendation according to the contact list.

In an embodiment of the present application, the method comprises step S14, in which: a record of historic communication between the first user and the second user is obtained; and an intimacy value between the first user and the second user is determined based on the record of the historical communication, and the record of the historical communication comprises at least one of: frequency of calls, duration of calls, and frequency of messaging; or an intimacy value between the first user and the second user is obtained from a first user equipment where the first user is located, and the intimacy value is determined by the first user equipment according to the record of the historical communication between the first user and the second user. Here, a record of historical communication between the first user and the second user may be obtained at first. The record of historical communication may be frequency of calls, such as number of calls within a month, duration of calls, such as total duration of calls or duration of each call, frequency of messaging, such as total number of messages sent within a month, etc. Intimacy between the first user and the second user may be calculated according to communication features in the record of the historical communication and corresponding weights thereof, and to provide better friend recommendation. An intimacy value which has been determined may also be obtained from a first user equipment directly, and the intimacy value is calculated by the first user equipment according to the record of the historical communication between the first user and the second user. Then, after the intimacy is calculated, the user information of the first user and the intimacy value between the first user and the second user may be sent to a recommended user list of the second user. For example, intimacy between user A and user B is 50, and intimacy between user C and user B is 80. In the recommended user list of user B, each recommended user is sorted according to the intimacy, and the corresponding intimacy is displayed, and the user B selects a recommended user more intuitively and sends a new friend request, and thus relevance and effectiveness of friend recommendation are enhanced.

In an embodiment of the present application, the method further comprises step S15, in which: a blacklist of the second user is obtained; and it is determined whether the first user is in the blacklist of the second user, and if so, sending the information of the first user to the recommended user list of the second user is rejected. Of course, in case where the first user is recommended to the second user as long as a contact list of the first user contains contact information of the second user, the second user may not intend to establish friend relationship with the first user, may not be interested in the first user, or may have deleted the first user or set the first user in a blacklist in history. Also, the first user may obtain the contact information of the second user in other ways. At this time, if the first user is recommended to the second user as long as the contact list of the first user contains the second user, it will cause disturbance to the second user, and degrade user experience. Therefore, the blacklist of the second user may be obtained at first, and then it is determined whether the first user is in the blacklist. If so, the first user is no longer recommended to the second user.

In an embodiment of the present application, when a first user is recommended to a second user, the first user to be recommended may also be determined according to an obtained history record that the second user did not agree to add a new friend and/or marking information on the first user by other users. The user information of the first user to be recommended is sent to a recommended user list of the second user. Here, in practical scenarios, some intermediary agents or other harassers may obtain contact information of the user in some ways, and the user does not want to be disturbed by these people. If these people are also recommended to the user, user experience will be degraded. Therefore, a record of the second user's historical behaviors regarding adding a new friend may be obtained, for example, information of users who have been rejected, or marking information on the first user by other users, such as an intermediary agent as marked or the like, then these people should be removed when providing friend recommendation to the second user. That is, the first user to be recommended is determined according to an obtained history record that the second user did not agree to add a new friend and/or marking information on the first user by other users. The first user to be recommended does not comprise a user that the second user refused to add as friend in history, and/or a user marked by other users as a harassing user, such as an intermediary agent, an advertisement promoter, or the like.

According to a further aspect of the present application, it is also provided a method for friend recommendation at a first user equipment. The method comprises: step S21 and step S22.

At step S21, user information of a first user and second user indication information are provided to a network device, and the second user indication information is used by the network device to determine a second user, and the network device sends the user information of the first user to a recommended user list of the second user. Here, a user uploads his/her own user information and information on his/her contact list, so that the network device determines contacts in the contact list who correspond to the uploading user according to the received information. A user whose contact list contains other user(s) may be identified as a first user, and it is determined whether the other user(s) contained in the contact list can be identified as a second user according to indication information of the other user(s). For example, if contacts in a contact list of user A contain user B, user A is a first user, and it is determined whether user B is a second user according to indication information of user B.

At step S22, a new friend request sent by the second user to the first user is received, and the new friend request sent by the second user to the first user is triggered by the second user selecting the first user in the recommended user list of the second user. After the network device determines the second user who corresponds to the first user, user information of the first user is sent to the second user. A new friend request event is triggered when the second user selects the first user in the recommended user list of the second user. The first user receives the new friend request from the second user, and establishes friend relationship with the second user upon approval of the new friend request.

It should be noted that, the first user equipment includes but is not limited to mobile electronic products capable of human-machine interaction with users via touchpads, for example, an intelligent phone, a PDA, etc. The mobile electronic products can run on any operating system, such as android operating system, iOS operating system, etc.

In an embodiment of the present application, the second user may be filtered at the first user equipment. The second user indication information comprises second user identification information, and a network device determines a second user according to the second user identification information. In specific, filtering contacts in the contact list of the first user and determining the second user identification information is obtained by: comparing, the first user equipment, information on a contact list of the first user with information on a friend list of the first user and determining identification information of a contact not in the friend list but in the contact list as the second user identification information. Comparison is conducted at the first user equipment at first, and then the network device receives the identification information of the second user determined by the comparison, and to send recommendation information for recommending a friend desired by the second user to the second user who has been determined according to the identification information, which can avoid distributing friend recommendation messages arbitrarily and can reduce the amount of data required by data transmission when reporting to the network device, saving network traffic, and thus reducing burden on the network device.

In an embodiment of the present application, when the second user indication information comprises information on a contact list of the first user, the network device may compare the information on the contact list of the first user with information on a friend list of the first user, and determining a contact not in the friend list but in the contact list as the second user. Here, when each of the contacts in the contact list of the first user is identified as the second user, it will cause invalid recommendation and a waste of system resources. Therefore, the information on the friend list of the first user may be uploaded to a network device, and thus one or more contacts in the contact list who have not established friend relationship with the first user are determined. The user information of the second user determined through the comparison is sent to the network device, and the network device recommends the first user to the second user.

In an embodiment of the present application, the method comprises step S23, in which: a record of historical communication with the second user is sent to the network device, and the network device determines an intimacy value between the first user and the second user according to the record of the historical communication, and sends the intimacy value between the first user and the second user to the recommended user list of the second user, and the record of the historical communication comprises at least one of: frequency of calls, duration of calls, and frequency of messaging. Here, the record of historical communication of a contact list of the first user may be sent to the network device at first, and then the network device calculates an intimacy value between the first user and the second user. Of course, an intimacy value between the first user and the second user may also be determined according to the record of the historical communication with the second user, and the network device sends the intimacy value between the first user and the second user to the recommended user list of the second user, and the record of the historical communication comprises at least one of: frequency of calls, duration of calls, and frequency of messaging. The intimacy value between the first user and the second user is sent to the network device. Here, the intimacy value between the first user and the second user may be calculated through the record of the historical communication of the contact list of the first user. Then the calculated intimacy value is sent to the network device, and the network device sends the intimacy value between the first user and the second user to the recommended user list of the second user. The intimacy value is calculated at the first user equipment at first, and then sent to the second user equipment through the network device, which can reduce the amount of data required by data transmission when reporting to the network device, saving network traffic, and thus reducing calculation burden on the network device.

According to a further aspect of the present application, it is also provided a method for friend recommendation at a second user equipment. The method comprises: step S31 and step S32.

At step S31, user information of a first user in a recommended user list sent by a network device is received, and the first user is determined, by the network device, according to information on a contact list of the first user and one of: information on a friend list of the first user, information on a friend list of a second user. Here, the first user is filtered and determined by the network device according to the contacts in the contact list and one of: information on a friend list of the first user, information on a friend list of a second user. For example, user B receives user information of the recommended user (user A), and thus the user information of user A is contained in a recommended user list of user B. User A is determined, by the network device, according to information on a contact list of user A as well as information on a friend list of user A or information on a friend list of user B. For example, if contacts in the contact list of user A contain user B, and there is no user B exists in the friend list of user A, or there is no user A exists in the friend list of user B, user A is a first user relative to user B and user B is a second user relative to user A at this time. Thus, reverse friend recommendation according to the contact list can be implemented by recommending user A to user B. The user information comprises information for identifying a user identity, such as a user name, a mobile phone number or the like.

At step S32, a new friend request is sent to the first user in the recommended user list, and friend relationship is established with the first user after receiving a notification sent by the first user indicating that the new friend request has been approved. Here, the second user sends a new friend request to the selected first user in the recommended user list based on the recommended user list. After the first user approved the new friend request, the second user establishes friend relationship with the first user. Thus, relevance and effectiveness of friend recommendation are enhanced by way of reverse friend recommendation according to the contact list, and the effect of expanding network of friend relationship quickly is achieved.

It should be noted that, the second user equipment includes but is not limited to mobile electronic products capable of human-machine interaction with users via touchpads, for example, an intelligent phone, a PDA, etc. The mobile electronic products can run on any operating system, such as android operating system, iOS operating system, etc.

A first user equipment 1 provides user information of a first user and second user indication information to a network device 2. The network device 2 determines a second user based on the second user indication information, and sends the user information of the first user to a recommended user list of the second user. The second user on the second user equipment 3 sends a new friend request to the first user in the recommended user list.

Here, the first user equipment 1 uploads the user information of the first user and the indication information of the second user to the network device 2. The network device 2 determines the second user contained in a contact list based on uploaded indication information of the second user, and distributes the user information of the first user obtained from the first user equipment 1 to the second user equipment 3 where the second user is located. Thus, the recommended user list is determined according to the received user information of the first user on the second user equipment 3, one or more recommended users are selected from the recommended user list, and a new friend request is sent. After the other party agreed, friend relationship is established with the other party, realizing reverse friend recommendation according the contact list, and achieving effect of expanding network of friend relationship quickly.
