METHOD OF ESTABLISHING COMMUNICATION RELATION WITH
COMMUNICATION OBJECT, TERMINAL AND SERVER
BACKGROUND OF THE INVENTION
Technical Field [0001] The present application relates to the field of instant messaging technology, and more particularly to a method of establishing a communication relation with a communication object, and corresponding terminal and server.
Description of Related Art

[0002] The instant messaging (IM) software has become an indispensable communication tool in everyday life of the people. Users can communicate with one other through client ends of the instant messaging software point-to-point or point-to-many, for instance, users can utilize the client ends of such software as SUNING Douya, WeChat, QQ, and DingTalk to communicate with other users.

[0003] Usually, the precondition enabling a user to communicate with other users is for the account of the user to have established communication relations in advance with the accounts of the other users, for example, the account of the user and the accounts of other users have mutually added friends with each other, or the account of the user and the accounts of other users reside in the same group. In the prior-art technology the user can share to other users the personal two-dimensional code of his account or the group two-dimensional code of the group in which his account resides (or which his account administers), the other users scan the personal two-dimensional code or the group two-dimensional code through the image recognition function (such as the "scan-in" function) of their client ends, and execute corresponding operations before the account of the user can be added as a friend or before the group in which the account of the user resides can be joined.

Date Recue/Date Received 2022-02-21

[0004] However, inconvenient cases somehow exist in practical applications by the modes of adding friends through code scanning or joining groups, for instance, there is valid period restriction for group two-dimensional codes (valid within 7 days, for example), there is group member number restriction for groups, there is total friend number restriction for each user, and each user can only be added as friend by a certain number of other users within a period of time (such as daily); for a user having plural accounts or having joined plural groups, due to the relatively many number of accounts or number of groups, there are also such many corresponding personal two-dimensional codes or group two-dimensional codes, while it is impossible for the user to conveniently administer the two-dimensional codes of the various accounts or groups due to restrictions mentioned above, and this may render problematic the personal two-dimensional codes or group two-dimensional codes shared by the user with other users (for instance, a shared group two-dimensional code might have expired the valid period, the number of friends of a personal account may have reached the upper limit, etc.), and this in turn would render complicated the processes for other users to add as friends and to join groups, for instance, another user scans a shared two-dimensional code only to find that the user cannot be added as friend because the total friend number of the user sharing the personal two-dimensional code has reached the upper limit (or the user has been added as friend by other users in excess of the restricted number in a short time), or to find that the group cannot be joined because the shared group two-dimensional code has expired the valid period, or the number of people in the group has exceeded the limit, so the operation to add as friend or to join the group has to be repeated again.

DETAILED DESCRIPTION OF THE INVENTION

[0061] To make more lucid and clear the objectives, technical solutions and advantages of the present application, the present application is described in greater detail below with reference to accompanying drawings and embodiments. As should be understood, the specific embodiments as described here are merely meant to explain the present application, rather than to restrict the present application.

[0062] Embodiment 1

[0063] Fig. 1 is a view illustrating the application environment for a method of establishing a communication relation with a communication object in an embodiment of the present invention. Communication terminal 13 in Fig. 1 is installed with a client end program of instant messaging software, the client end program has logged in the user account of a user, the user (hereinafter referred to as "code scanning user") can execute a first operation on a Date Recue/Date Received 2022-02-21 first barcode image in an operation interface of the client end program, communication terminal 13 jumps in response to the first operation from a current page to a middle page that contains a second barcode image obtained from a barcode administration server according to the first barcode image, the second barcode image carries therewith invitation information to which a communication object (hereinafter referred to as "target communication object") corresponds, when the code scanning user executes a second operation on the second barcode image, communication terminal 13 decodes the second barcode image to obtain the invitation information, and subsequently displays a page (hereinafter referred to as "invitation page") obtained from instant messaging server 14 according to the invitation information, the code scanning user can execute a third operation in the invitation page to send a request to the instant messaging server for requesting to establish a communication relation between the current communication object (namely the user account currently logged in by the client end program) and the target communication object, and the instant messaging server will establish the communication relation for the two communication objects in response to the request.

[0064] Moreover, the first barcode image can come from a user (hereinafter referred to as "code creating user") of configuration terminal 11 (it is of course also possible for the first barcode image to come from any other user), for instance, the code creating user prints the first barcode image on a poster, and the code scanning user scans the poster in real time via the "scan-in" function at his client end program to obtain the first barcode image printed on the poster; the code creating user can also send the first barcode image to communication terminal 13 through a user account in which communication relation has been established with the user account of the code scanning user, and thus communication terminal 13 can display the first barcode image it receives. Furthermore, the code creating user can firstly request barcode administration server 12 to create the first barcode image through configuration terminal 11, when the user needs to share the first barcode image, Date Recue/Date Received 2022-02-21 the first barcode image well created by the user can be requested and obtained from barcode administration server 12 through configuration terminal 11. In the embodiments of the present invention, barcode images (including the first barcode image, the second barcode image, and the object barcode image(s)) can be one-dimensional codes, two-dimensional codes or multi-dimensional codes. Configuration terminal 11 and communication terminal 13 can each be, but are not limited to be, any of various personal computers, notebook computers, smart mobile phones, panel computers and desktop computers, etc., and barcode administration server 12 and instant messaging client end 14 can each be embodied as an independent server or a server cluster consisting of a plurality of servers.

[0065] The present embodiment provides a method of establishing a communication relation with a communication object, and the method is explained below with an example of its being applied to communication terminal 13 in Fig. 1. As shown in Fig. 2, the method comprises the following steps.

[0066] S110 - receiving a first operation executed by a user on a first barcode image, wherein the first barcode image is used to obtain a second barcode image associated therewith (with the first barcode image) from a barcode administration server.

[0067] In this embodiment, the first operation executed by the user is used to instruct the communication terminal to perform a barcode recognizing process on the first barcode image. As should be noted, operations for instructing the communication terminal to perform a barcode recognizing process on the first barcode image may be different in different scenarios.

[0068] For example, in a scenario, the first barcode image is a picture stored in the communication terminal, the step of receiving a first operation executed by a user on a first barcode image Date Recue/Date Received 2022-02-21 can include receiving a first operation executed by a user on a first barcode image in a page (for instance, a page communicative with the communication object, a page of WeChat Moments, etc.) that contains the first barcode image, wherein the first operation is used to instruct to perform a barcode recognizing process on the first barcode image.
As shown in Fig. 3-a, what the communication terminal currently displays is a chat page between the user and user A, user A sends a first barcode image to the user, and the user can keep pressing on the first barcode image to instruct the communication terminal to perform a barcode recognizing process on the first barcode image.

[0069] For another example, in another scenario, the first barcode image is not a picture stored in the communication terminal, suppose the image is currently displayed in a screen (it can also be disposed on another object, such as being printed on a poster or a propaganda document), at this time the user can directly activate the "scan-in" function to scan in real time the first barcode image displayed on the screen, the scanning interface can be as shown in Fig. 3-b, whereupon the communication terminal will automatically shoot and perform a barcode recognizing process on the shot picture that contains the first barcode image; the user can also firstly use the camera of the communication terminal to shoot the first barcode image displayed on the screen, then enter the client end program of the instant messaging software, and employ the barcode recognizing function supplied by the client end program to perform a barcode recognizing process on the picture just shot to contain the first barcode image; suppose the picture icon at the lower right corner in Fig. 3-b is the entrance to the barcode recognizing function, at this time, having entered the "scan-in"
interface, the user can click this picture icon whereby an image selection interface can be entered, and the user firstly selects the picture he shot to contain the first barcode image and then clicks the "confirm" button in the interface, thusly it is made possible to instruct the communication terminal to perform a barcode image recognizing process on the picture selected by the user.

[0070] S120 ¨jumping, in response to the first operation, from a current interface to a middle page that contains the second barcode image obtained according to the first barcode image, wherein the second barcode image carries therewith invitation information to which a target communication object corresponds.

[0071] As shown in Fig. 3-c, having received the first operation coming from the user, the communication terminal jumps from the current interface to a middle page in response to the first operation executed by the user on the first barcode image, and the middle page contains therein the second barcode image. The middle page is so obtained that the communication terminal decodes the first barcode image and uses the information obtained by such decoding to request from the barcode administration server, the communication terminal performs a barcode recognizing process on the first barcode image to obtain information carried with the first barcode image, and bases on the information carried therewith (with the first barcode image) to obtain the second barcode image from the barcode administration server, and the second barcode image will be displayed by being contained in a page (namely middle page).

[0072] In one mode of execution, the step of jumping, in response to the first operation, from a current interface to a middle page that contains the second barcode image obtained according to the first barcode image includes the following steps as shown in Fig. 4:

[0073] S121 - decoding the first barcode image in response to the first operation to obtain barcode identifications and access information of the barcode administration server carried with the first barcode image;

[0074] S122 - establishing connection with the barcode administration server according to the access information, and containing the barcode identifications in a middle page obtaining request and sending the same to the barcode administration server through the connection Date Recue/Date Received 2022-02-21 to obtain the second barcode image; and

[0075] S123 - receiving middle page rendering data returned by the barcode administration server, and displaying the middle page that contains the second barcode image according to the middle page rendering data.

[0076] In this mode of execution, the barcode identifications are requested and created by the user that creates the first barcode image (namely code creating user) from the barcode administration server, the access information can be a URL (Uniform Resource Locator), the communication terminal can access to the server to which the URL
corresponds after having obtained this URL, request rendering data of the middle page (namely middle page rendering data), and hence display the middle page according to the rendering data as obtained. The rendering data can be an HTML (HyperText Markup Language) file.
Exemplarily, the process for the communication terminal to display the middle page according to the rendering data can be as follows: the communication terminal downloads to obtain the HTML file to which the middle page corresponds from the barcode administration server according to an HTTP (HyperText Transfer Protocol), then reads the HTML file, initiates requests top down according to links in the HTML file (one request corresponds to one link), and can render and display the page after all page elements (such as texts, pictures, audios, animations, programs, etc.) in the HTML file have been requested and obtained. If a requested page element is a picture, the communication terminal will render the picture while downloading it.

[0077] In the barcode administration server, each first barcode image corresponds to at least one object barcode image, the object barcode image is a barcode image carrying with invitation information of another communication object, which can be a personal two-dimensional code or a group two-dimensional code, and is uploaded to the barcode administration server by the user that creates the first barcode image. Having received any middle page obtaining Date Recue/Date Received 2022-02-21 request, the barcode administration server can determine all object barcode images having mapping relations therewith according to the barcode identifications carried with the request, and thereafter base on a barcode determining rule preset by the user that creates the first barcode image to determine therefrom the second barcode image, namely all object barcode image(s) that satisfies/satisfy the rule. Exemplarily, the second barcode image can be an image or images simultaneously satisfying the following conditions in all object barcode images to which the barcode identifications correspond, the conditions include:
that/those with the highest priorities, that/those within a preset valid period of image, and that/those whose remaining number of returns (a difference between the maximum number of returns of the image and the number of returns of the current image) being greater than 0. The priority, valid period of image and maximum number of returns of image of each object barcode image can be set by the code creating user.

[0078] S130 ¨ displaying an invitation page obtained according to the invitation information to which the target communication object corresponds in response to a second operation executed by the user on the second barcode image in the middle page.

[0079] In this embodiment, the second operation is used to instruct the communication terminal to perform a barcode recognizing process on the second barcode image. The second operation can be to keep pressing on the second barcode image by the user, for instance, after the communication terminal has displayed the middle page as shown in Fig. 3-c, the user keeps pressing on the two-dimensional code image displayed on the middle page, whereby it is made possible to instruct the communication terminal to perform a barcode recognizing process on this two-dimensional code image.

[0080] As should be noted, the second barcode image can be a personal two-dimensional code or a group two-dimensional code, so the page entered after the barcode recognizing process Date Recue/Date Received 2022-02-21 has been performed on the second barcode image might be different in different instant messaging softwares, for instance, after the barcode recognizing process has been performed on a personal two-dimensional code in a client end program of certain instant messaging software, the page (namely invitation page) displayed by the communication terminal can be the page (or interface) as shown in Fig. 5-a, whereas after the barcode recognizing process has been performed on a group two-dimensional code, the page displayed by the communication terminal can be the page as shown in Fig. 5-b.

[0081] In one mode of execution, the step of displaying an invitation page obtained according to the invitation information to which the target communication object corresponds in response to a second operation executed by the user on the second barcode image in the middle page includes:

[0082] decoding the second barcode image in response to the second operation to obtain invitation information of a target communication object carried therewith; and

[0083] displaying an invitation page for confirming with the user whether to establish a communication relation with the target communication object according to the invitation information of the target communication object.

[0084] The invitation information of the communication object (namely target communication object) carried with the second barcode image can be an object identification of the communication object in the instant messaging server, and can further include link information for obtaining an invitation page, so that the communication terminal bases on the link information to obtain from the instant messaging server relevant resources related to the communication object for display in the invitation page, for example, such resources can include, but are not limited to, username of the communication object, location information, user head portrait, signature information, group name, group member number, etc.

Date Recue/Date Received 2022-02-21

[0085] S140 ¨ sending a request to an instant messaging server for requesting to establish a communication relation with the target communication object in response to a third operation executed by the user in the invitation page.

[0086] In this embodiment, if the communication terminal detects that the user has executed a third operation in the invitation page, for example, the button of "click to apply adding as friend" has been clicked in the page as shown in Fig. 5-a (in certain scenarios, after the user has clicked this button, an interface requiring the filling-in of verification information is firstly popped up, in which case it is required for the user to add verification information to this interface before clicking again a button to submit the verification information), or the button of "click to join group" has been clicked in the page as shown in Fig. 5-b, the communication terminal will send a request to the instant messaging server for requesting to establish a communication relation with the target communication object. On receiving this request, the instant messaging server performs a corresponding operation, for example, to directly establish a friend relation between the user account of the user and the user account of a user whom is applied to be added as friend, or to directly pull the user in a group the user applies to join, for another example, to firstly send the verification information filled in by the user to a login device of the user account that is applied by the user to be added as friend, or to a login device of an administrator account of a group applied to be joined, and then to establish a friend relation between the user account of the user and the user account of a user whom is applied to be added as friend, or to directly pull the user in a group the user applies to join when passing of friend verification is fed back from the relevant login device or when an instruction allowing to join the group is received.

[0087] In the embodiments of the present invention, having received a first operation executed by Date Recue/Date Received 2022-02-21 a user on a first barcode image, the communication terminal jumps in response to the first operation from a current interface to a middle page that contains a second barcode image obtained according to the first barcode image from a barcode administration server, wherein the second barcode image carries therewith invitation information to which a target communication object corresponds, on further receiving a second operation executed by the user on the second barcode image in the middle page, the communication terminal displays in response to the second operation an invitation page obtained according to invitation information to which the target communication object corresponds, and on receiving a third operation executed by the user in the invitation page, the communication terminal sends a request to an instant messaging server requesting to establish a communication relation with the target communication object in response to the third operation. The embodiments of the present invention enable users to obtain valid personal two-dimensional codes or group two-dimensional codes, avoid the circumstance in which it is required to scan the code again due to failure of adding friend or failure of joining group after a user has scanned a personal two-dimensional code or a group two-dimensional code, and simplify operations when users establish communication relations with other communication objects.

[0088] On the other hand, the code creating user can change the object barcode images associated with the first barcode image and the relevant configuration records (such as the priorities of the images) of the various object barcode images through interaction of the configuration terminal and the barcode administration server; since the first barcode image is not much associated with the instant messaging server, it is not restricted by the valid period and is also not subjected to the restriction of the maximum number of code scannings, and it is useable once it is created; when the code creating user needs to add a code scanning user as friend or to pull the code scanning user in a group, it suffices to share the corresponding first barcode image to the code scanning user, in particular as regards a user having plural Date Recue/Date Received 2022-02-21 user accounts or having joined plural groups, the user can conveniently administer the plural user accounts he possesses or the plural groups he presides by creating a plurality of first barcode images, for instance, the code creating user presides over plural English language studying and discussing groups, and English learners can be conveniently attracted into these plural English language studying and discussing groups merely by creating a first barcode image, subsequently uploading group two-dimensional codes of all the English language studying and discussing groups to be associated with the first barcode image, performing relevant configurations (such as configuring priorities and the maximum number of returns of the image) on the various group two-dimensional codes, and thereafter sharing the first barcode image by the code creating user.

[0089] Embodiment 2

[0090] Based on the same inventive conception as Embodiment 1, the present invention provides another method of establishing a communication relation with a communication object in Embodiment 2, and this method of establishing a communication relation with a communication object is applicable to the barcode administration server shown in Fig. 1.

[0091] As shown in Fig. 6, the method of establishing a communication relation with a communication object comprises the following steps:

[0092] S210 - receiving a middle page obtaining request, wherein the middle page obtaining request is for communication terminal to response to a first operation executed by a user on a first barcode image, decoding the first barcode image to obtain barcode identifications and access information for establishing connection with a current server carried with the first barcode image, establishing connection with the current server according to the access information, and containing the barcode identifications in the middle page obtaining request and sending out the same through the connection;
Date Recue/Date Received 2022-02-21

[0093] S220 - determining a second barcode image from all object barcode images to which the barcode identifications correspond according to a preset barcode determining rule; and

[0094] S230 - returning, to the communication terminal, middle page rendering data that contains rendering data for obtaining the second barcode image, so as to enable the communication terminal to display a middle page that contains the second barcode image according to the middle page rendering data.

[0095] In this embodiment, the barcode identifications are requested and created by the user (namely the user that creates the first barcode image) from the barcode administration server, the access information can be a URL (Uniform Resource Locator), the communication terminal can access to the server to which the URL corresponds after having obtained this URL, request rendering data of the middle page (namely middle page rendering data), and hence display the middle page according to the rendering data as obtained. The rendering data can be an HTML (HyperText Markup Language) file.
Exemplarily, the process for the communication terminal to display the middle page according to the rendering data can be as follows: the communication terminal downloads to obtain the HTML file to which the middle page corresponds from the barcode administration server according to an HTTP (HyperText Transfer Protocol), specifically, the communication terminal sends a middle page obtaining request that contains the barcode identifications to the barcode administration server, the barcode administration server feeds back the HTML file to the communication terminal in response to the request, the communication terminal reads the HTML file on receiving the HTML file, initiates requests top down according to links in the HTML file (one request corresponds to one link), and can render and display the page after all page elements (such as texts, pictures, audios, animations, programs, etc.) in the HTML file have been requested and obtained. If a requested page element is a picture, the communication terminal will render the picture while downloading it.

Date Recue/Date Received 2022-02-21

[0096] In the barcode administration server, each first barcode image corresponds to at least one object barcode image, the object barcode image is a barcode image carrying with invitation information of another communication object, which can be a personal two-dimensional code or a group two-dimensional code, and is uploaded to the barcode administration server by the user that creates the first barcode image. Having received any middle page obtaining request, the barcode administration server can determine all object barcode images having mapping relations therewith according to the barcode identifications carried with the request, and thereafter base on a barcode determining rule preset by the user that creates the first barcode image to determine therefrom the second barcode image, namely all object barcode image(s) that satisfies/satisfy the rule. Exemplarily, the second barcode image can be an image or images simultaneously satisfying the following conditions in all object barcode images to which the barcode identifications correspond, the conditions include:
that/those with the highest priorities, that/those within a preset valid period of image, and that/those whose remaining number of returns (a difference between the maximum number of returns of the image and the number of returns of the current image) being greater than 0. The priority, valid period of image and maximum number of returns of image of each object barcode image can be set by the code creating user.

[0097] This embodiment enables the communication terminal to return valid personal two-dimensional codes or group two-dimensional codes, avoids the circumstance in which it is required to scan the code again due to failure of adding friend or failure of joining group after a user has scanned a personal two-dimensional code or a group two-dimensional code, and simplifies operations when code scanning users establish communication relations with other communication objects.

[0098] In one mode of execution, before the barcode administration server receives the middle Date Recue/Date Received 2022-02-21 page obtaining request, the method further comprises:

[0099] receiving a first barcode image creating request sent by a configuration terminal;

[0100] obtaining image configuration information to which the first barcode image creating request corresponds and all object barcode images uploaded by the configuration terminal, wherein the image configuration information includes configuration information to which each said object barcode image corresponds, and the configuration information to which each said object barcode image corresponds includes valid period configuration information and maximum number of returns configuration information;

[0101] creating barcode identifications, obtaining user information to which the configuration terminal corresponds, establishing mapping relations between the barcode identifications and the user information, and establishing mapping relations between the barcode identifications and all the object barcode images uploaded by the configuration terminal;

[0102] creating a configuration record to which each said object barcode image corresponds according to the image configuration information, wherein the configuration record includes a valid period of image, a maximum number of returns of image, and a number of returns of the current image; and

[0103] updating the number of returns of the current image corresponding to any said object barcode image after the object barcode image has been returned to any communication terminal.

[0104] In this mode of execution, the barcode administration server can provide the user with a configuration interface for creating the first barcode image, exemplarily, such a configuration interface can be as shown in Fig. 7, the user can create an associated first barcode image for plural object barcode images, such as group two-dimensional codes or personal two-dimensional codes, through the configuration interface, and the user can further configure a valid period of image, a maximum number of returns of image, and a priority of the image for each of the various object barcode images. The barcode Date Recue/Date Received 2022-02-21 administration server records the number of returns of the current image to which each object barcode image corresponds, so that the remaining number of returns can be calculated out according to the maximum number of returns of the image configured by the user.

[0105] Moreover, the step of determining a second barcode image from all object barcode images to which the barcode identifications correspond according to a preset barcode determining rule includes:

[0106] determining all object barcode images having mapping relations with the barcode identifications according to pre-established mapping relations to which the barcode identifications correspond; and

[0107] selecting an object barcode image that satisfies a preset barcode determining rule from all the object barcode images according to the configuration record to which each said object barcode image corresponds to serve as the second barcode image.

[0108] The barcode administration server maintains the configuration record of each object barcode image, including such information as the priority of the image, valid period of image, and the maximum number of returns of image, so that, whenever the barcode administration server receives a middle page obtaining request coming from any communication terminal, it is possible to base on the configuration record of each relevant object barcode image (namely the object barcode image having a mapping relation with a barcode identification) to screen out of the object barcode images the valid object barcode image(s) that conform(s) to the preset barcode rule.

[0109] In another mode of execution, before the barcode administration server receives the middle page obtaining request, the method further comprises:

[0110] receiving a first barcode image obtaining request sent by the configuration terminal;

Date Recue/Date Received 2022-02-21

[0111] obtaining user information to which the configuration terminal corresponds, and determining barcode identifications to which the user information corresponds;

[0112] generating a first barcode image carrying therewith the barcode identifications and the access information; and

[0113] returning the first barcode image to the configuration terminal.

[0114] After the user has created the first barcode image, when it should be shared to other users, a first barcode image obtaining request can be sent to the barcode administration server through the configuration terminal, thus the barcode administration server obtains relevant barcode identifications based on the user information to which the request corresponds, subsequently generates thereby a barcode image, namely the first barcode image, carrying therewith the barcode identifications and access information, and thereafter returns the same to the configuration terminal.

[0115] The barcode administration server can also create a barcode identification when the user issues an instruction to create the first barcode image through the configuration interface, and generate the first barcode image on the basis of this barcode identification, so that, when the first barcode image obtaining request is received, the first barcode image generated in advance can be directly returned to the configuration terminal.

[0116] Moreover, in one mode of execution, the barcode administration server can monitor the valid period of image and the remaining number of returns of each object barcode image uploaded by the user, and send a reminder message to the user (in the form of a mail, a short message, etc.) when the valid period of image of the object barcode image is nearing expiration or when the remaining number of returns approaches zero, so as to remind the user to replace the object barcode image whose valid period of image is nearing expiration or whose remaining number of returns approaches zero with a new one, for instance, the Date Recue/Date Received 2022-02-21 valid period of image of the group two-dimensional code of a certain group is 1 day, the barcode administration server then sends a reminder message to the user to facilitate the user to upload a new group two-dimensional code of the group, thus it can be guaranteed that all object barcode images to which the first barcode image corresponds remain valid, i.e., being within the valid period of image, or not exceeding the upper limit of the number of times being added as friends.

[0117] Specific definitions relevant to the method of establishing a communication relation with a communication object in this embodiment can be further inferred from the definitions to the method of establishing a communication relation with a communication object in Embodiment 1, and the overlapped portions will not be redundantly described in this context.

[0118] As should be noted, Figs. 2, 4 and 6 are flowcharts schematically illustrating the methods of establishing a communication relation with a communication object provided by Embodiments 1 and 2. As should be understood, although the various steps in the flowcharts of Figs. 2, 4 and 6 are sequentially displayed as indicated by arrows, these steps are not necessarily executed in the sequences indicated by arrows.
