Description

User selection method and system

Technical field

The present invention relates to communication network systems, and more particularly to condition based user selection methods and systems. Background technique

With the development of telecommunication technology, the future business is rich and colorful. In the session establishment phase of many services, users who need to join the session need to be selected according to certain conditions. These conditions will be based on various information possessed by the user, such as presentation (Presence). Information, location information, and user interests and hobbies.

In the existing communication technologies, different user information is divided into different servers, such as presence information exists on a presence server, such information including user online information, network bearer information, client device application capability information, and users. Information such as hobbies and moods. The location information is present on the Location server, which indicates the geographic location where the user is currently located.

For example, to obtain a list of users located near a certain mall and having an online status, it is necessary to make a judgment and selection based on the current presence information of the user and their geographical location information to obtain a list of users satisfying the above conditions.

1 is a schematic diagram showing the configuration of a user selection system in the related art. As shown in FIG. 1, first, the requester sends a request to the presence server 102 through the terminal device 101, wherein the request carries a status condition (online) to obtain a user uniform resource identifier whose status is online (URI: Universal Resource Identifier); Then, the requester sends a request to the location server 103 through the terminal device 101, and the geographical condition (near the mall) carried by the request is obtained to obtain the user uniform resource identifier URI of the geographic location near the mall. After obtaining the uniform resource identifier URI of the above user, the requester will perform a comprehensive analysis according to the user uniform resource identifier URI, and obtain a user list that satisfies the condition, that is, the state near the mall and whose status is online.

It can be seen from the above that when the user list is obtained by the above system, the requester needs to use its terminal device 101 to send a request to a different status information server to obtain the status of the user, and the requester himself needs to compare the returned results. The requester needs to know the information held by each server, and the requester's terminal device 101 needs to have an interface to various different servers, so that when the user list is obtained, the requester is brought a large inconvenient.

2 is a schematic diagram showing the structure of a condition-based user selection system in the related art. As shown in FIG. 2, the requester uses its terminal device 201 to send a request or condition for information such as a geographical location, presentation, and the like to The user selection server 202, the user selection server 202 is connected to various state information servers, for example, to a server such as the presence server 203, the location server 204, etc., obtains presence information from the presence server 203, and obtains geographic location information from the location server 204, according to the obtained The information is analyzed and integrated, and the user URI satisfying the requester's transmission condition is transmitted to the requester's terminal device 201, so that the CBUS: Condition Based URIs Selection system is used, and the requester's terminal device 201 is not required. Direct interaction with a variety of servers, the requester does not need to analyze the trace according to the obtained information, nor need to configure different interfaces on the requester's terminal device 201, only need to submit the requirements to The user selects the server 203, so that the condition-based user selection system can bring certain convenience to the requester, and solve the problem in the user selection system of FIG.

However, in the CBUS system, the CBUS system selects the user, and the meaning of the selection condition is the condition that the user should have. In the user selection process, the selection server 202 of the CBUS system needs to perform a single search on each condition to obtain a corresponding search result, that is, a user list; then, through the "and" operation, the search result is re-selected to obtain the user expectation. As a result, the search process is complicated, and the algorithm is single, the search takes a long time, and the efficiency is low.

Therefore, the user who meets different state conditions, logical relationships, and user ranges can be selected by the embodiment of the present invention. The method is accurate and efficient, and brings great convenience to the requester.

Embodiment 2

The embodiment of the present invention further provides a user selection system. As shown in FIG. 4A, the system further includes a receiving unit 402 and a selecting unit 403. The receiving unit 402 and the selecting unit 403 have the same functions as in the first embodiment. I won't go into details here.

As shown in FIG. 4A, the system further includes a request sending unit 401, and the request sending unit is configured to send the request message to the receiving unit 402. Figure 5 is a block diagram showing the configuration of the selection unit of Figure 4A. As shown in FIG. 5, the selection unit 403 includes a first parsing unit 501, a first processing unit 502, and a first result obtaining unit 503.

The first parsing unit 501 is configured to parse the selection condition to obtain a logical relationship between the user range, the status condition, and the status condition; wherein, if there is no user range in the selection condition, the first parsing The unit 501 adopts a default user range, that is, all users; the first processing unit 502 is configured to acquire a user set corresponding to the state condition within the user range; the first result obtaining unit 503 is configured to collect the user according to the logical relationship. Perform logical operations to obtain user selection results.

Figure 6 is a block diagram showing the structure of the first processing unit of Figure 5. The first processing unit 502 includes: a state information acquiring unit 601 and a first user set obtaining unit 602; wherein the state information acquiring unit 601 is configured to acquire state information of all users corresponding to each type of information to which the state condition belongs; The first user set obtaining unit 602 is configured to select a user set that meets the corresponding status condition from the status information of each of the users to obtain a user set corresponding to the status condition.

Further, as shown in FIG. 4A, the system may further include a storage unit 404 that may store the acquired state information of the user. In this way, the acquired user state information is temporarily stored. When the request sending unit 401 requests the state information of the same user again, the selecting unit 403 may first acquire the temporarily stored user state information and use it for the user selection operation.

As shown in FIG. 4A, the system further includes a timer 405 and a maintenance unit (not shown); wherein the timer 405 is configured to time the status information of the user temporarily stored in the storage unit 404. The maintenance unit is configured to determine whether the time of storing the state information of the user stored in the storage unit 404 exceeds the preset effective time. If the determination result is over, the state information of the user is deleted from the storage unit 404. As shown in FIG. 4A, the system further includes an information providing unit 406 for providing status information of all users corresponding to the type of information to which the status condition belongs.

In this way, when the first processing unit 502 in the selecting unit 403 obtains the user state information, it may first determine whether the state information of the user corresponding to the information type to which the state condition belongs is temporarily stored in the storage unit 404; if the determination result is yes, The status information of the user corresponding to the information type to which the status condition belongs is directly obtained from the storage unit 404. If the determination result is no, the status information of the user is obtained from the information providing unit 406 corresponding to the information type to which the status condition belongs.

It can be seen from the above that since the state information of the user often changes, it is necessary to set an effective time for the temporarily stored state information, and the effective time is related to the type of the state information, for example, the effective time of the static information is longer, such as the user's Hobbies; and variable state information should be valid Shorter, such as the user's location information. After the selection unit 403 obtains a user status information, the status information of the user is first saved, and then the status information of the user is timed by the set timer 405. When the preset valid time is exceeded, the temporary storage is deleted. Status information for the user.

In this embodiment, as shown in FIG. 4B, the request sending unit 401 can be implemented by using the user terminal device 407. The receiving unit 401, the selecting unit 403, the storage unit 404, and the timer 405 can be implemented by the selection server 408. The information providing unit 406 is implemented by a corresponding information providing server 409, such as a presence server, a location server, or the like. The user terminal device 407 can perform information interaction with the selection server 408 by wire or wirelessly, and send a request message to the selection server 408, and the selection server 408 returns the selection result to the user terminal device 407; The server 408 can perform information interaction with the information providing server 409 through the network. However, it is not limited to the above implementation manner, and may be implemented in other manners.

In addition, by temporarily storing the acquired user status information in the storage unit 404 of the selection server 408, when the selection server 408 requests the status information of the same user again according to the request message, the temporary user status information may be acquired first, and used. The user selects the operation, which greatly reduces the data interaction between the selection server 408 and the information providing server 409.

It can be seen from the above embodiment that when the first parsing unit 502 in the selecting unit 403 processes a plurality of state conditions, the user selection under each state condition is simultaneously performed, and then the end user selection is obtained according to the logical relationship between the respective state conditions. result. Therefore, the system can select users satisfying different state conditions, logical relationships, and user ranges, and the method is accurate and efficient, and brings great convenience to the requester.

Embodiment 3

The embodiment of the present invention further provides a user selection system. As shown in FIG. 4A, the system includes a request sending unit 401, a receiving unit 402, a selecting unit 403, a storage unit 404, a timer 405, a maintenance unit, and an information providing unit 406. The functions of the request sending unit 401, the receiving unit 402, the selecting unit 403, the storing unit 404, the timer 405, the maintenance unit, and the information providing unit 406 are similar to those in the second embodiment, and are not described herein again.

Fig. 7 is a schematic view showing the configuration of a selection unit of the third embodiment. As shown in FIG. 7, the selection unit includes a second parsing unit 701, a second processing unit 702, and a second result obtaining unit 703;

The second parsing unit 701 is configured to parse the selection condition to obtain a logical relationship between a user range, a status condition, and the status condition;

The second processing unit 702 is configured to process the state condition in sequence, and obtain the data in succession. a collection of users corresponding to each state condition;

The second result obtaining unit 703 is configured to determine a user selection result according to the logical relationship and the user set corresponding to each state condition.

In this embodiment, when the second processing unit 702 processes the two state conditions in the state condition in sequence, the following manner may be adopted: the user set corresponding to the previous state condition and the logic corresponding to the state condition The relationship updates the user scope, and the updated user scope is used to obtain the user collection corresponding to the post state condition. When the two state conditions are sequentially processed in order, regardless of the logical relationship between the sequential state conditions, the order of processing need not be considered, and the processing order may be arbitrary.

In this embodiment, after the second processing unit 702 obtains the user set corresponding to the previous state condition, and updates the user range, the following manner may be adopted:

When the logical relationship corresponding to the two state conditions is a logical sum, the user set that meets the previous state condition is used as the updated user range;

When the logical relationship corresponding to the two state conditions is logical OR, the prior user scope is removed from the user set that meets the previous state condition as the updated user range;

When the logical relationship corresponding to the two state conditions is logically non-existent, if the logical non-corresponding state condition is processed first, the prior user scope is removed from the user set that meets the post-state condition as the updated user range; When a state condition that does not correspond to a logical one is processed, the user set that meets the prior condition is used as the updated user range.

Correspondingly, when the second processing unit 702 processes two corresponding user sets according to the logical relationship, the following manner may be adopted:

When the logical relationship corresponding to the two state conditions is a logical sum, the user set that meets the post state condition is taken as the user selection result.

When the logical relationship corresponding to the two state conditions is logical OR, the user sets that meet the two state conditions are merged, and the combined result is used as the user selection result.

When the logical relationship corresponding to the two state conditions is logically non-existent, the user set that meets the post-state condition is taken as the user selection result. It can be seen from the above embodiment that the second processing unit 702 processes each state condition in batches in order, and updates the user range selected one time according to the user selection result selected in the previous condition, thereby greatly reducing user selection. The number of selections at the time, the selection efficiency is high, and the user is greatly facilitated.

In this embodiment, as shown in FIG. 4B, the request sending unit 401 can adopt a user terminal device. 407 to achieve. The receiving unit 401, the selecting unit 403, the storage unit 404, the timer 405, and the maintenance unit may be implemented by the selection server 408. The information providing unit 406 is implemented by a corresponding information providing server 409, such as a presence server, a location server, or the like. The user terminal device 407 can perform information interaction with the selection server 408 by wire or wirelessly, and send a request message to the selection server 408, and the selection server 408 returns the selection result to the user terminal device 407; The server 408 can perform information interaction with the information providing server 409 through the network. However, it is not limited to the above implementation manner, and may be implemented in other manners.

In this way, the selection server 408 acquires the status information of the user in the information providing server 409 corresponding to each status condition in batches according to the selection condition sent by the requester, and updates the user range selected one time later according to the user selection result selected in the previous condition. In this way, the number of users requesting status information for the last several times can be reduced, the communication traffic between the selection server 408 and the information providing server 409 is saved, and the load of the information providing server is also reduced.

Embodiment 4

The embodiment of the invention further provides a user selection method. FIG. 8 is a flowchart of a user selection method according to Embodiment 4 of the present invention. As shown in FIG. 8, the method includes: receiving a request message for performing user selection, where the request message carries at least one selection condition, where the selection condition includes a logical relationship between at least two state conditions and the state condition, and / or user range (see step 801); user selection is made according to the selection condition to obtain a user selection result that meets the selection condition (see step 802).

In this embodiment, the logical relationship between the state conditions is one of a logical sum, a logical OR, and a logical non.

The user selection method of the embodiment of the present invention will be described in detail below with reference to FIGS. 4B and 9. Step 901: The user sends a request message to the selection server 408 through the terminal device 407. The request message carries at least one selection condition, where the selection condition includes a logical relationship between the at least two status conditions and the status condition, and/or User scope. Step 902: After receiving the request message, the selection server 408 parses the request message to obtain a logical relationship between the user scope, the status condition, and the status condition. The user does not include the user in the request message. In the range, the selection server 408 can determine that the user range is all users.

Step 903: The selection server 408 respectively obtains a set of users corresponding to the status condition in the user scope; wherein, the following manner may be adopted:

Obtaining, from the storage unit of the information providing server 409 or the selection server 408, state information of all users corresponding to each type of information belonging to each state condition in the user range; respectively selecting the corresponding state condition from the state information of each user A collection of users to obtain a collection of users corresponding to the state condition.

Step 904, performing logical operations on each user set according to the logical relationship to obtain a final user selection result.

Step 905, the selection server 408 returns the user selection result to the user terminal device 407. As can be seen from the above, in step 903, when the state condition is processed, the user selection under each state condition is simultaneously performed, and then the final user selection result is obtained based on the logical relationship between the respective state conditions. Through the above method, users who meet different state conditions, logical relationships, and user ranges can be selected, and the method is accurate and efficient, and brings great convenience to the requester.

In step 903, the selection server 408 can also store the acquired user state information. When the selection server 408 requests the state information of the same user again according to the request message, the selection server 408 can first determine whether the selection server 408 is temporarily stored. The user status information corresponding to the status condition, if the determination result is yes, the selection server 408 can directly obtain the user status information from the temporarily stored information without being acquired from the information providing server 409, and if the determination result is the selection server 408 The user status information is not temporarily stored, and is acquired from the corresponding information providing server 409. In this way, the number of interactions between the selection server 408 and the information providing server 409 can be greatly reduced.

In addition, since the state information of the user often changes, in order to ensure the reliability of the acquired state information of the user, the selection server 408 can also set a valid time for the temporarily stored state information. In this embodiment, the effective time may be related to the type of the status information. Generally, the status information may include status information of the static condition and status information of the dynamic condition, so that the effective time of the static information may be set longer, such as The user's hobbies, and the effective time setting of the dynamically variable status information should be shorter, such as the user's location information. Thus, when the selection server 408 stores the status information of a user, a timer is set for the status information, when the time is equal to Or when the valid time corresponding to the status information of the type is exceeded, that is, when the time expires, select the server.

408 will delete the temporary status information, so that the status information of the user on the selection server 408 can be automatically maintained, the load of the selection server 408 is reduced, and the reliability of the acquired status information of the user is guaranteed.

The user selection method of the embodiment of the present invention will be described in detail below with reference to FIG. 4B and FIG. Step 1001: The user sends a request message to the selection server 408 through the terminal device 407. The request message carries at least one selection condition, where the selection condition includes a logical relationship between the at least two status conditions and the status condition, and/or the user. range.

Step 1002: After receiving the request message, the selection server 408 parses the request message to obtain a logical relationship between the user scope, the status condition, and the status condition. The user does not include the user in the request message. In the range, the selection server 408 can determine that the user range is all users.

Step 1003: The selection server 408 processes the state conditions in sequence, and sequentially obtains a set of users corresponding to each state condition.

Step 1004: The selection server 408 processes the user set corresponding to each state condition according to the logical relationship to obtain a user selection result.

Step 1005, finally the selection server 408 transmits the obtained user selection result to the user terminal device 407.

In this embodiment, in step 1003, when the selection server 408 processes the two state conditions in the state condition in sequence, the user may be based on the user set corresponding to the previous state condition and the logical relationship corresponding to the state condition. The scope is updated, and the updated user scope is used to obtain the user set corresponding to the post state condition, thereby reducing the number of data interactions between the selection server 408 and the information providing server 409.

Figure 11 is a flow chart showing the processing of two of the plurality of state conditions in sequence according to an embodiment of the present invention. As shown in FIG. 11, step 1101, determining whether the type of the logical relationship between the two state conditions is logically non-linear;

Step 1102: In step 1101, if the determination result is no, the user set corresponding to one of the two status conditions is obtained;

Step 1103: Update a user range according to a logical relationship between the obtained user set and the sequence status condition.

Step 1104, using the updated user range to obtain another status bar of the two status conditions. The corresponding user collection.

In step 1103, when the logical relationship of the two state conditions is a logical sum, the user set that meets the previous state condition is used as the updated user range; in the updated user scope, the user set that meets the post state condition is set. As a result of user selection.

In step 1103, when the logical relationship between the two state conditions is logical OR, the prior user scope is removed from the user set that meets the previous state condition as the updated user scope; correspondingly, in step 1004, according to the logic When the relationship is processed by the user set corresponding to the two state conditions, the user sets that meet the two state conditions are merged, and the merged result is used as the user selection result.

In step 1101, if the result of the determination is that the logical relationship is logically non-exclusive, the method further includes: Step 1105: First, perform a user selection operation under a logical non-targeted state condition, that is, first obtain a corresponding one of the two consecutive status conditions. a collection of users of logical non-state conditions;

Step 1106: Update the user range according to the obtained user set.

Step 1107, using the updated user scope to obtain a user set corresponding to another state condition. Correspondingly, when processing two corresponding user sets according to a logical relationship, the method comprises: using a user set that meets another state condition as a user selection result.

In step 1106, when the user scope update is performed, when the condition that the logic is not targeted is processed, the prior user scope is removed from the user set that meets the post state condition as the updated user scope; in the updated user scope, The user set that meets the previous state condition is taken as the result of the user selection.

In the above embodiment, whether or not the logical relationship between the conditions is determined to be logical is not only an embodiment of the present invention, but is not limited thereto, and it may be first determined whether the logical relationship is "or" or "and". And when the judgment result is logically non-existent, each condition can be processed in the normal order, not only the condition for logical non-determination is determined first.

In this embodiment, in steps 1102, 1104, 1105, and 1107, a user set corresponding to a state condition is obtained, and the following manner may be adopted:

Obtaining state information of all users corresponding to the information type to which the state condition belongs; in this case, first determining whether the state information of all users corresponding to the information type to which the state condition belongs is temporarily stored in the selection server 408, and if so, directly from the state information The selection server 408 obtains the status information. Otherwise, the status information is obtained from the corresponding information providing server 409.

Finally, a set of users that meet the status condition is selected from the status information of all the users. Through the above embodiment, the selection server 408 can batchize according to the selection conditions sent by the requester. Obtaining the status information of the user in each status condition corresponding information providing server 409, and updating the user range according to the user set corresponding to the previous status condition and the logical relationship corresponding to the status condition, and using the updated user range to obtain the next time. The user condition corresponds to the set of users, thereby reducing the number of users requesting status information for the last several times, saving communication traffic with the status information server, and reducing the load of the status information server.

In addition, since the status information of the user often changes, the selection server 408 can also set a valid time for the temporarily stored status information in order to ensure the reliability of the acquired status information of the user. In this embodiment, the effective time may be related to the type of the status information, such as the effective time of the static information, such as the user's hobbies, and the variable status information should be shorter, such as the user's location information. Thus, when the selection server 408 stores the status information of a user, a timer is set for the status information, and when the time is equal to or exceeds the valid time corresponding to the status information of the type, that is, when the time expires, The server 408 will delete the temporary state information, so that the user information on the selection server 408 can be automatically maintained, the load of the selection server 408 is reduced, and the reliability of the acquired state information of the user is ensured.

In the foregoing embodiment, when the user status information is obtained in batches, when there is a logical non-logical relationship, the operation of the logical non-operation may be considered first, but for other logical relationships, the execution order is not limited and may be arbitrarily selected.

When at least two state conditions are processed in batches in sequence, the order of processing may be arranged according to the type of the state information, and the state information of the static condition may be acquired first, and then the state information of the dynamic condition is obtained.

For different state conditions, there are different effective times. Generally, the effective time can be set according to the state information type. The state information can include state information of the static condition and state information of the dynamic condition, so that the effective time of the static information can be set. Long, such as the user's hobbies, and the effective time setting of the dynamically variable status information should be shorter, such as the user's location information. In this way, the state information corresponding to the longer effective time can be obtained first, and then the state information corresponding to the shorter effective time is obtained. Because the effective time is longer, it is more likely to obtain the state information of the target user from the temporarily stored state information, and Because this kind of information is temporarily stored for a long time, it can select services for more users in the future, so the state information acquisition work is performed first. At this time, the user range used is large, and the obtained state information can have more application value; The status information with a short effective time is then executed after the status information is acquired. At this time, the user range used is small, and the temporary uselessness caused by the short effective time can be assumed.

The embodiments of the present invention are described in detail below through specific examples. Embodiment 5

Zack hopes to establish a chat room with his colleagues to discuss the contents of the work. There are 6 colleagues, but Beijing colleagues don't have to go to work because of the unique festivals in China. Zack only needs to discuss work with colleagues who are on the phone but not in Beijing. Zack acts as a requester to send a user selection request message to the selection server through its terminal device, wherein the request message includes a logical relationship between the user range, the status condition, and the status condition.

The user scope is a list of 6 people, including the contact information of 6 people, as shown in Table 1. The status condition is: (Presence = Power On) not (11^ = Beijing).

Table 1

After the selection server receives the user selection request message, it sends the information to the server, for example

The Presence server requests Presence information for 6 people, and requests the location information of 6 people from the location server to obtain status information of 6 people, as shown in Table 2.

Table 2

The selection server determines that Alice, Chris, David, Emily are all powered on, meets the (Presence = boot) condition, determines that Al ice is located in Beijing, and meets the condition of (L0C = Beijing), then the server selects the logic according to the state condition. The relationship "not", to determine Chris, David, Emily meet the selection criteria, and return to Zack a list of eligible users, namely Chris, David and Emi ly. Embodiment 6

The same scenario as in the fifth embodiment. After receiving the user selection request message, the server selects the location information of the 6 persons from the location server to obtain the location information (the content of the information is in accordance with Table 2), and determines that the Al ice is located in Beijing and meets the condition of (L0C = Beijing). Then, the server is selected to update the user range according to the logical relationship "not", and the updated user scope does not include Al ice; then, the selection server sends a list of 5 persons after the Al ice to the Presence server, and requests the presence information of the 5 persons. After obtaining the Presence of 5 people (information content and Table 2), judge Chris, David, Emi ly to meet the selection criteria, and return to Zack a list of users who meet the requirements, namely Chris, David and Emi ly.

Compared with the fifth embodiment, the embodiment selects one less user list for requesting the Presence information from the server to the Presence server. The Presence server does not need to retrieve and return Al ice Presence information to the selection server.

Example 7

The publisher wants to post a promotional ad for the mall, which is located in Beijing and the promotion is the day of the day. Therefore, the publisher wants to send it to everyone near the mall and to users who have subscribed to the service and are located in Beijing. The publisher, as a requester, sends a user selection request message to the selection server, providing a list of 51 subscribers. The complete selection criteria are: ((51 people list, (11^=Beijing)) or (Everyone , (L0C = near the mall) and (Presence = boot))).

After the server selects the request message, it obtains the list of all the boot users from the Presence server. The Presence server returns the list of users whose current Presence status is powered on, for a total of 83,975 people. The user selects the server and sends the list of 83975 people to the location server, requests the location information of the 83975 people, the location server returns the latitude and longitude information of the people, and the selection server calculates the distance between the 83975 people and the mall, wherein the distance is less than 1 km. There are 1746 people. Select the server to compare the list of 51 people provided by the publisher, and find that 5 of them are in the list of 1746 people obtained last time, then select the server to send the list of the remaining 46 of the 51 people to the location server, requesting the location of the 46 people. Information, it is known that 32 of them are located in Beijing. Then the server is selected to return a list of 1768+32 1768 people to the publisher.

Example eight

Zack hopes to set up a chat room with his colleagues to discuss the content of the work. There are 6 colleagues. Zack only needs to discuss the work with the startup colleagues. Zack as a requester to choose clothes The server sends a user selection request message, which includes a logical relationship between the user range, the status condition, and the status condition. The user scope is a list of 6 people, including the contact details of 6 people, as shown in Table 3. The status condition is: ^361^6 = boot).

table 3

After receiving the user selection request message, the server selects the Presence information of 6 people from the Presence server, and temporarily stores the information shown, and provides a valid time, as shown in Table 4.

Table 4

The selection server returns to Zack a selection result including Al ice, Chris, David, and Emily to complete the user selection operation. Yang then initiates a user selection request operation as a requester. A five-person user list is provided in the request message, as shown in Table 5, and the status condition is (Presence Table 5).

The server selects the Presence information of 5 people from the temporary user status information, obtains the Presence information of Emily and Frank, and then selects the server to request the Presence information of Gray, Hans and Jack from the Presence server, and obtains the following result, and The Presence information of Gray, Hans and Jack is temporarily stored, as shown in Table 6.

Table 6

Select the server to return to Yang a list of Emi ly, Gray, Hans, and Jack.

When the selection server determines that the Presence information of Al ice or the like is valid for 26 minutes, the selection server deletes the Presence information of the temporarily stored Alice, Bob, Chris, David, Emily, and Frank.

Example nine

The publisher wants to publish a promotional ad for the mall, which is sports items. Therefore, the publisher wants to send the advertisement to everyone who is near the mall and whose personal hobby is sports. The publisher, as a requester, sends a user selection request message to the selection server, providing a list of 51 people, hoping that the selection server can return a list of users whose interests are sports and located near the store. The complete selection criteria are: (list of 51 people, ((L0C = near the mall) and (personal hobby = sports))).

Because the personal preference information is static information, and the location information is dynamic information, the selection server first sends a message to the information providing server after receiving the user selection request message sent by the requester (such as network address book information, wherein the personal interests of the recorded contacts are recorded) In the information), 51 people's personal hobbies are inquired, and 20 of them have a personal preference for sports, which meets the requirements of the selection criteria.

The server is selected to obtain the location information of 20 people from the location server, and the location information of 20 people returned by the location server is determined, and 6 of them are determined to meet the selection condition requirement, and the 6-person list is returned to the requester.

Example ten

The embodiment of the invention provides a user selection method. The method includes: Receiving a request message for performing user selection; wherein the request message carries at least one selection condition, the selection condition including a logical relationship between the at least two status conditions and the status condition;

User selection is performed based on the information carried by the request message to obtain a user selection result in accordance with the request.

In this embodiment, the request message may further include a user scope, and when the user scope is not included, the user scope is defaulted to all users.

In this embodiment, the status condition is condition information for a user status, such as a geographic location condition such as "user is located in Beijing" and a user network status condition such as "user online".

The selection condition is a combination of state conditions when the user selects, and includes at least one state condition. When the selection condition includes a plurality of state conditions, the logical relationship between the plurality of state conditions is also included.

The user selection method of the embodiment of the present invention will be described in detail below with reference to FIG. 4B and FIG. Step 1201: The user sends a request message to the selection server 408 through the terminal device 407.

If the determination result is that the selection server 408 does not temporarily store the evaluation information of the user, the corresponding information is obtained from the corresponding information. The server 409 is provided for acquisition. In this way, the number of interactions between the selection server 408 and the information providing server 409 can be greatly reduced.

In addition, since the evaluation information of the user often changes, the selection server 408 can also set a valid time for the temporarily stored evaluation information in order to ensure the reliability of the evaluation information of the acquired user. In this embodiment, the effective time may be related to the type of the evaluation information. Generally, the evaluation information may include evaluation information of the static condition and evaluation information of the dynamic condition, so that the effective time of the static information may be set longer, such as The user's hobbies, and the effective time of the dynamically variable evaluation information is set shorter, such as the user's location information. Thus, when the selection server 408 stores the evaluation information of a user, a timer is set for the evaluation information, when the time of the timing is equal to or exceeds the effective time corresponding to the evaluation information of the type, that is, when the time expires, The server 408 will delete the temporary evaluation information, so that the evaluation information of the user on the selection server 408 can be automatically maintained, the load of the selection server 408 can be alleviated, and the reliability of the acquired evaluation information of the user can be guaranteed.

The user selection method of the embodiment of the present invention will be described in detail below with reference to FIG. 4B and FIG. Step 1301: The user sends a request message to the selection server 408 through the terminal device 407. The request message carries at least one selection condition, where the selection condition includes a logical relationship between the at least two status conditions and the status condition. It can also carry a range of users.

Step 1302: After receiving the request message, the selection server 408 parses the request message to obtain a logical relationship between the user scope, the status condition, and the status condition. Wherein, when the request message does not include the user range, The selection server 408 can determine that the user range is all users.

Step 1303: The selection server 408 processes the state conditions in sequence, and sequentially acquires a set of users corresponding to each state condition.

Step 1304, the selection server 408 processes the user set corresponding to each state condition according to the logical relationship to obtain a user selection result.

Step 1305, finally the selection server 408 transmits the obtained user selection result to the user terminal device 407. In this embodiment, in step 1303, the selection server 408 processes the two state conditions in the state condition in sequence, as described in FIG. 11 in the fourth embodiment, and details are not described herein again.
