[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0024] Please refer to Figure 1 , which shows a schematic diagram of a computer system provided by an embodiment of the present application. The computer system can be implemented as a long connection establishment system. The computer system may include: a terminal device 10 and a server 20.

[0025] The number of terminal devices 10 may be one or more. The terminal device 10 may be an electronic device such as a mobile phone, a tablet computer, a laptop computer, a desktop computer, a game console, an e-book reader, a multimedia player, a wearable device, a smart TV, a vehicle-mounted terminal, etc. The first client corresponding to the target application may be installed in the terminal device 10. Optionally, the target application may be an application that needs to be downloaded and installed, or may be a point-and-click application, which is not limited in the embodiment of the present application. In the embodiment of the present application, the above-mentioned target application is an application with a function of establishing a long connection. Of course, the specific type of the target application is not limited, and the type of the target application may be a music application, a video application, an animation application, a social application, a question-and-answer application, a virtual reality application, an augmented reality application, etc. The embodiment of the present application does not limit the specific category of the target application. In other embodiments, the target application may be considered as a separate functional module, such as being implemented as one of the functional modules in the music application for implementing the establishment of a long connection. Exemplarily, the above-mentioned first client is running in the terminal device 10.

[0026] The server 20 is used to provide background services for the client of the target application installed and running in the terminal device 10. For example, the server 20 can be the background server of the above-mentioned target application. The server 20 can be a single server, or a server cluster composed of multiple servers, or a cloud computing service center. Optionally, the server 20 provides background services for the clients of the target application in multiple terminal devices 10 at the same time. The terminal device 10 and the server 20 can communicate with each other through the network.

[0027] In some embodiments, in response to the first client being started, it is detected whether the first client belongs to a defined group, the defined group including at least one client selected to establish a long connection with the server; if the first client belongs to the defined group, a long connection establishment request is sent to the server, the long connection establishment request being used to request to establish the long connection with the server.

[0028] The method provided in the embodiment of the present application may be performed by a computer device. The computer device may be any electronic device that has the ability to store and process data. For example, the computer device may be Figure 1 The terminal device 10 may also be a server 20.

[0029] HTTP (Hypertext Transfer Protocol) is one of the cornerstones of modern Internet communication. It defines the rules for data exchange between clients and servers. In HTTP communication, there are two main connection modes: short connection and long connection. Short connection means that a new TCP (Transmission Control Protocol) connection is established for each request-response interaction. This means that each HTTP request needs to go through the TCP three-way handshake and four-wave handshake process, which consumes time and resources. Once the response is completed, the connection is closed immediately. Long connection (also called persistent connection or HTTP Keep-Alive) allows multiple request-response interactions on the same connection. In this way, the TCP connection between the client and the server remains open for a period of time and can be reused without having to repeatedly establish and close the connection. This greatly reduces the overhead of connection establishment and teardown, improving performance and efficiency.

[0030] There are many advantages to using HTTP persistent connections, especially in high-traffic and high-concurrency scenarios:

[0031] 1. Reduce the overhead of connection establishment and removal: Long connections avoid unnecessary TCP handshake and wave processes, reducing network delays and resource consumption.

[0032] 2. Improved performance: Persistent connections between clients and servers allow more request-response interactions, thereby speeding up data transfer.

[0033] 3. Reduce server load: Long connections reduce the number of connections opened simultaneously on the server, reduce the burden on the server, and improve scalability.

[0034] 4. Better user experience: Users can load web pages and applications faster because the connection remains open, reducing waiting time.

[0035] In the related art, there are two situations regarding the method of establishing a long connection. One is to establish a long connection according to the full amount of devices. That is, all terminal devices with the client installed establish a long connection, which results in a high cost for establishing a long connection. The other is to establish a long connection according to the user account. That is, only the client that logs in to the user account establishes a long connection, and the client that does not log in to the user account does not establish a long connection. This situation cannot cover the scenario of the user account not being logged in, and may cause the user to be unable to obtain information in a timely manner.

[0036] An embodiment of the present application provides a method for establishing a persistent connection, which can determine the client that needs to establish a persistent connection according to a defined range, while reducing the cost of establishing a persistent connection and covering a variety of scenarios including user accounts that are not logged in.

[0037] Please refer to Figure 2 , which shows a flow chart of a method for establishing a long connection provided by an embodiment of the present application. The method includes at least one of the following steps 210 to 220.

[0038] Step 210 , in response to the first client being started, the first client detects whether the first client belongs to a defined group, where the defined group includes at least one client selected to establish a persistent connection with the server.

[0039] Client, or user end, refers to a program that corresponds to a server and provides local services to users. In addition to some applications that only run locally, they are generally installed on ordinary terminal devices and need to cooperate with the server to run. After the development of the Internet, the more commonly used user ends include web browsers used for the World Wide Web, email clients for sending and receiving emails, and instant messaging client software. For this type of application, there needs to be a corresponding server and service program in the network to provide corresponding services, such as database services, email services, etc. In this way, a specific communication connection needs to be established between the terminal device and the server to ensure the normal operation of the application.

[0040] In some embodiments, the defined group is determined by the server. In some embodiments, the defined group may be fixed or dynamically changed. Exemplarily, the defined group may change following the planning of the first client. Exemplarily, if the first client carries out a planning activity, such as a lottery, then the defined group may be the first client that is eligible to participate in the planning activity. Exemplarily, if the first client launches a new version of the internal testing activity, then the defined group may be the first client that has been updated to the internal testing version. In some embodiments, the defined group may be determined based on the operating conditions of the first client, the user portrait of the first client, etc., and this application does not limit this, and the above content is only illustrated as an exemplary embodiment.

[0041] In some embodiments, the first client is installed and runs on the first terminal device. In some embodiments, the first client startup refers to the first client startup on the first terminal device. In some embodiments, after the first client is started, it can run in the foreground or in the background, which is not limited in this application. In some embodiments, the startup of the first client can be triggered by the user or by the operating system of the first terminal device, which is not limited in this application. Exemplarily, the startup of the first client can be triggered based on the user's startup operation. Exemplarily, the startup of the first client can be triggered with the startup of the operating system of the first terminal device.

[0042] In some embodiments, detecting whether the first client belongs to the defined group can be based on a mark cached by the first client, or can be performed by sending a query message to the server, which is not limited in this application. Exemplarily, the first client caches a first mark, and the first mark is used to indicate that the client belongs to the defined group within a first time period, so the first client is considered to belong to the defined group. Exemplarily, the first client caches a second mark, and the second mark is used to indicate that the client does not belong to the defined group within a second time period, so the first client is considered not to belong to the defined group. Exemplarily, the first client sends a query message to the server, and the query message is used to query whether the first client belongs to the defined group, and determines whether the first client belongs to the defined group based on the response information fed back by the server.

[0043] Step 220: When the first client belongs to the defined group, the first client sends a persistent connection establishment request to the server, where the persistent connection establishment request is used to request to establish a persistent connection with the server.

[0044] In some embodiments, when the first client belongs to a defined group, the first client sends a persistent connection establishment request to the server to trigger a persistent connection establishment process.

[0045] In some embodiments, when the first client does not belong to the defined group, the first client does not send a persistent connection establishment request, and there is no need to trigger a persistent connection establishment process.

[0046] In some embodiments, after receiving the persistent connection establishment response sent by the server, the persistent connection establishment is completed. The first client and the server can communicate through the persistent connection.

[0047] In some embodiments, the long connection will not be actively closed, and subsequent read and write operations will continue to use this connection. Under normal circumstances, after a TCP long connection is established, as long as both parties do not make a closing request and no abnormal situation occurs, this connection will always exist. The operating system will not automatically close it, and it can still be used even after the physical network topology changes. Therefore, it is possible for a connection to remain for several days, months, years or even longer, as long as there is no abnormal situation or it is actively closed by the user (application layer). The first client and the server can always use this connection for data communication. Long connections can save more TCP establishment and closing operations, reduce the impact of network congestion, and when an error occurs, prompts can be given without closing the connection, reducing the use of CPU and memory because there is no need to frequently establish and close connections.

[0048] The technical solution provided by the embodiment of the present application triggers the process of establishing a long connection with the server only when the first client belongs to the defined group. If the first client does not belong to the defined group, there is no need to establish a long connection between the first client and the server. There is no need to maintain a long connection based on the full amount of devices, which can effectively reduce the cost of establishing a long connection and reduce the power consumption of the server in maintaining a long connection.

[0049] How to determine whether the first client belongs to the defined group

[0050] 1. Determine by sending a query message to the server

[0051] In some embodiments, please refer to Figure 3 , the above step 210 can be implemented as at least one of the following steps 211 to 230.

[0052] Step 211: The first client sends query information to the server, where the query information is used to query whether the first client belongs to a defined group.

[0053] Step 212: The first client receives response information sent by the server, where the response information is used to indicate whether the first client belongs to a defined group.

[0054] Step 213: The first client determines whether the first client belongs to or does not belong to the defined group based on the response information.

[0055] In some embodiments, the response information may directly indicate whether the first client belongs to a defined group, or may indirectly indicate whether the first client belongs to a defined group, which is not limited in the present application.

[0056] In some embodiments, the response information directly or indirectly indicates whether the first client belongs to a defined group, which may affect the information carried in the query information and the response information. The two situations will be discussed below in a classified manner.

[0057] Case 1: The response information directly indicates whether the first client belongs to the defined group

[0058] In some embodiments, after receiving the query information, the server determines whether the first client belongs to a defined group.

[0059] In some embodiments, the query information includes relevant information of the first client. In some embodiments, after receiving the query information, the server determines whether the first client belongs to a defined group based on the relevant information of the first client included in the query information.

[0060] In some embodiments, the query information does not include relevant information of the first client. After receiving the query information, the server instructs the first client to report relevant information of the first client, and after obtaining the relevant information of the first client, determines whether the first client belongs to the defined group.

[0061] In some embodiments, the relevant information of the first client is used by the server to determine whether the first client belongs to a defined group. Exemplarily, the relevant information of the first client includes at least one of the following information: identification information of the first client, login information of the first client, user portrait corresponding to the first client, and geographic location corresponding to the first client. Login information refers to whether the first client is logged in to the user account. User portrait is a labeled user model abstracted from various characteristics and behaviors of the user, which can help precision marketing, user research, personalized services and business decisions. Geographical location refers to the geographical location of the first terminal device where the first client is installed and running.

[0062] In some embodiments, the response information includes first indication information or second indication information, the first indication information is used to indicate that the first client belongs to a defined group, and the second indication information is used to indicate that the first client does not belong to the defined group. In some embodiments, when the first client belongs to the defined group, the response information sent by the server carries the first indication information; when the first client does not belong to the defined group, the response information sent by the server carries the second indication information.

[0063] In some embodiments, when the first client belongs to the defined group, the server sends a response message, and the response message is used to indicate that the first client belongs to the defined group; when the first client does not belong to the defined group, the server does not send a response message, and the first client does not receive the response message, which means that the first client does not belong to the defined group. In some embodiments, the first client does not receive the response message within the third time period, which means that the first client does not belong to the defined group. In some embodiments, the start time of the third time period is the time when the query information is sent.

[0064] Case 2: The response information indirectly indicates whether the first client belongs to the defined group

[0065] In some embodiments, after receiving the response information, the first client determines whether the first client belongs to the defined group based on the content carried in the response information.

[0066] In some embodiments, the response information includes first condition information, and the first condition information is used to indicate the characteristics of the client belonging to the defined group. In some embodiments, after receiving the response information, the first client determines whether the first client belongs to the defined group based on the first condition information.

[0067] In some embodiments, the first condition information includes at least one of the following:

[0068] The first sub-information is used to indicate whether the client belonging to the defined group has logged into the user account;

[0069] The second sub-information is used to indicate the conditions satisfied by the user profile corresponding to the client belonging to the defined group;

[0070] The third sub-information is used to indicate the conditions satisfied by the geographical locations corresponding to the clients belonging to the defined group.

[0071] In some embodiments, the first client determines whether the first client belongs to the defined group based on the first condition information. In some embodiments, if the first condition information is met, the first client belongs to the defined group; if the first condition information is not met, the first client does not belong to the defined group.

[0072] In some embodiments, the features of the client belonging to the defined group may also include other information, and the above three sub-information are only used as examples for explanation here. Exemplarily, the features of the client belonging to the defined group are defined based on the new function of the first client. For example, when a new function is grayed out, select a suitable client, including a client with a logged-in user account or a client with a non-logged-in user account; for example, pay attention to the experience of the young user group and define the client with a young user account logged in; for example, pay attention to the experience of the non-logged-in user and define the client with a non-logged-in user account, and so on.

[0073] In some embodiments, the response information includes first range information, and the first range information is used to indicate a restricted group. In some embodiments, the first range information includes identification information of clients belonging to the restricted group.

[0074] In some embodiments, if the first range information includes identification information of the first client, it indicates that the first client belongs to a defined group; if the first range information does not include identification information of the first client, it indicates that the first client does not belong to the defined group.

[0075] 2. Determined by local cache tag

[0076] In some embodiments, when the first client belongs to a defined group, a first flag is cached, where the first flag is used to indicate that the first client belongs to the defined group within a first time period.

[0077] In some embodiments, when the first client does not belong to the defined group, a second flag is cached, where the second flag is used to indicate that the first client does not belong to the defined group during the second period of time.

[0078] When the first client belongs to the defined group, the first mark is cached, and when the first client does not belong to the defined group, the second mark is cached. In this way, when it is necessary to detect whether the first client belongs to the defined group next time, the mark cached by the first client can be used to determine whether it belongs to the defined group. In some embodiments, since the defined group can be variable, a valid time can be assigned to the mark, and the first mark is valid in the first time period, and the second mark is valid in the second time period.

[0079] In some embodiments, in response to the first client starting, the query information is used to determine whether the first client belongs to the defined group. In some embodiments, the start time of the first period and the start time of the second period are both the time when the response information is received, and the response information is used to indicate whether the first client belongs to the defined group.

[0080] In some embodiments, in response to the first client being started, the first client receives notification information broadcast by the server, and the notification information includes first condition information or first range information. The first client can determine whether the first client belongs to the defined group based on the notification information. In some embodiments, the start time of the first time period and the start time of the second time period are both the reception time of the notification information, and the notification information is used to indicate whether the first client belongs to the defined group.

[0081] In some embodiments, the duration of the first time period and / or the second time period may be indicated by the server or may be preconfigured. Exemplarily, the response information and / or the notification information also includes first duration information, and the first duration information is used to indicate the duration of the first time period and / or the second time period. In some embodiments, the starting time of the first time period and / or the second time period may also be indicated by the server. Exemplarily, the response information and / or the notification information also includes first time information, and the first duration information is used to indicate the starting time of the first time period and / or the second time period.

[0082] In some embodiments, the duration of the first time period may be the same as or different from the duration of the second time period, and this application does not limit this. For example, the duration of the first time period is t1, and the duration of the second time period is t2, and t1 may be equal to t2 or may not be equal to t2. In some embodiments, the duration of the first time period or the duration of the second time period may also be 0.

[0083] In some embodiments, the first mark or the second mark may also be cached locally when the first client was last started, and the startup and shutdown of the first client does not affect the timing of the first time period or the second time period. In some embodiments, the shutdown of the first client means that the first client stops running, and the long connection with the server will be disconnected after the first client stops running. Exemplarily, the first client caches the first mark when it is started for the first time, and when it is started for the second time, it is still in the first time period, so there is no need to detect again whether the first client belongs to the defined group, and directly send a long connection establishment request to the server.

[0084] In some embodiments, in the first time period, in response to the effective duration of the long connection timing out, the first client again sends a long connection establishment request to the server. In some embodiments, since the defined group can change dynamically, the server can assign a valid duration to the long connection. During the valid duration, the server will not actively disconnect the long connection between the first client and the server. After the effective duration times out, the server actively disconnects the long connection with the first client. At this time, if it is still in the first time period, the first client sends a long connection establishment request to the server again to establish a new long connection. In some embodiments, in the second time period, the first client does not send a long connection establishment request to the server.

[0085] In some embodiments, when the network status of the first client changes (such as mobile network & Wifi (Wireless Fidelity) switching, disconnection, reconnection), the long connection will also be disconnected. Some other force majeure factors such as poor network status, DHCP (Dynamic Host Configuration Protocol) lease expiration, etc. will cause the long connection to be disconnected. After the long connection is disconnected, if it is still within the first time period, there is no need to re-detect whether the first client belongs to the circled range, and a long connection establishment request can be sent directly to the server.

[0086] In some embodiments, after the first period or the second period times out, the first client may also update the first mark or the second mark.

[0087] In some embodiments, in response to the end of the first time period or the second time period, it is detected again whether the first client belongs to the circled group; when the first client changes from belonging to the circled group to not belonging to the circled group, the cached first mark is updated to the second mark; when the first client changes from not belonging to the circled group to belonging to the circled group, the cached second mark is updated to the first mark.

[0088] Regarding detecting whether the first client belongs to a defined group, reference may be made to the description of the above embodiment, and the present application will not elaborate on it here.

[0089] In some embodiments, when the first client changes from belonging to the defined group to not belonging to the defined group, the cached first mark is updated to the second mark, and the valid period is updated from the first period to the second period; when the first client changes from not belonging to the defined group to belonging to the defined group, the cached second mark is updated to the first mark, and the valid period is updated from the second period to the first period.

[0090] In some embodiments, when the first client still belongs to the defined group, the first time period is extended. In some embodiments, the third time period is extended based on the first time period. In some embodiments, the third time period may be the same as the first time period or may be different from the first time period, and this application does not limit this. In some embodiments, the third time period may be pre-configured or may be configured by the server based on the method of determining the defined group.

[0091] In some embodiments, when the first client still does not belong to the defined group, the second time period is extended. In some embodiments, the fourth time period is extended based on the second time period. In some embodiments, the fourth time period may be the same as the second time period or may be different from the second time period, and this application does not limit this. In some embodiments, the fourth time period may be preconfigured or may be configured by the server based on the method of determining the defined group.

[0092] 3. Periodically check whether the first client belongs to the defined group

[0093] In some embodiments, after the first client is started, the first client periodically detects whether the first client belongs to a defined group.

[0094] In some embodiments, when the first client is closed, the persistent connection between the first client and the server is disconnected. In some embodiments, after detecting that the first client switches from belonging to a defined group to not belonging to a defined group, the persistent connection between the first client and the server is disconnected.

[0095] In some embodiments, the period for detecting whether the first client belongs to the defined group is indicated by the server. Exemplarily, the server indicates the first time period through a response message or a notification message, and the first time period is used to indicate the period duration for detecting whether the first client belongs to the defined group. In some embodiments, if the query message is used to detect whether the first client belongs to the defined group, the start time of the periodic detection is the time when the query message is sent. In some embodiments, if the notification message is used to obtain whether the first client belongs to the defined group, the start time of the periodic detection is the time when the notification message is received. In some embodiments, if the notification message is used to obtain whether the first client belongs to the defined group, the server can periodically send notification messages, and the first client only needs to periodically receive notification messages.

[0096] In some embodiments, the first time period may be predefined or determined by the server. For example, the first time period may be determined by the server based on the network status of the first client. If the network status of the first client is poor, the first time period may be shorter; if the network status of the first client is better, the first time period may be longer.

[0097] The technical solution provided in the embodiment of the present application triggers the process of establishing a long connection with the server only when the first client belongs to the defined group. When the first client does not belong to the defined group, there is no need to establish a long connection between the first client and the server. There is no need to maintain a long connection based on the full amount of the device, which can effectively reduce the cost of establishing a long connection and reduce the power consumption of the server to maintain a long connection. Clients that are not logged in to the user account can also establish a long connection, and clients that are logged in to the user account can also establish a long connection on demand, which can reduce the cost of establishing a long connection while covering more scenario requirements.

[0098] Please refer to Figure 4 , which shows a flowchart of a method for establishing a long connection provided by an embodiment of the present application.

[0099] The target user account / device is determined by the server. There are many scenarios for defining the user range. The scenarios for defining the target group as needed are as follows: for example, when a new feature is grayed out, select appropriate users, including logged-in users or non-logged-in users; for example, focus on the overall experience of young users and define all young accounts; for example, focus on the experience of non-logged-in users and define non-logged-in devices, etc.

[0100] The front end (first client) obtains whether the current account / device needs to establish a long connection, and automatically queries when the first client is started, without user operation.

[0101] In addition, there is no need to query and establish a persistent connection every time. A control time period can be issued, and logged-in users can also connect on demand. The control period is to query whether to establish a persistent connection mark, and then cache the mark locally on the client for a period of time; if there is a mark locally, there is no need to query the mark again at startup. There are many ways here, such as caching for a period of time t1 with a mark, not caching without a mark, or caching for a period of time t2 (t1 does not necessarily have to be equal to t2); in addition, it is not necessary to only start the call, but also to call periodically.

[0102] Taking the music application as an example, the first client is a music client. In response to the music client being started, the music client detects whether the music client belongs to a defined group, which includes at least one client selected to establish a long connection with the server. If the music client belongs to the defined group, the music client sends a long connection establishment request to the server, which is used to request to establish a long connection with the server. After the long connection is established, the music client can realize real-time data exchange with the server. Exemplarily, the user can listen to songs on the music client without downloading or caching.

[0103] Taking a game application as an example, the first client is a game client. In response to the game client being started, the game client detects whether the game client belongs to a defined group, which includes at least one client selected to establish a long connection with the server. If the game client belongs to the defined group, the game client sends a long connection establishment request to the server, which is used to request to establish a long connection with the server. After the long connection is established, the game client can realize real-time data exchange with the server. Exemplarily, after the long connection is established, the game client can provide a better quality image service.
