Description

Method for maintaining heartbeat mechanism, WLAN client and program server

technical field

The invention relates to communication technology, in particular to a method for maintaining a heartbeat mechanism, a WLAN client and a program server.

Background technique

When the terminal device uses the wireless local area network (Wireless Local Area Networks, WLAN for short) of the communication operator to obtain network resources, it usually runs the WLAN client application program on the terminal device, and sends an authentication request to the portal server (Portal server for short) through the WLAN client application program To establish a network connection to obtain network resources, the Portal server receives the authentication request of the terminal device and authenticates the terminal device. After the Portal server passes the authentication request of the terminal device, the terminal device can obtain network resources.

For a terminal device installed with a Windows (Windows) or Android (Android) operating system, after the terminal device establishes a network connection through the WLAN client application program, the terminal device user can switch the WLAN client application program to run in the background. After the client application is switched to run in the background, it can regularly send heartbeat packets to the Portal server according to the heartbeat interval set by the Portal server. The packet can know that the terminal device user wishes the terminal device to maintain a network connection, and if the Portal server does not receive the heartbeat packet, it can know that the terminal device user wishes the terminal device to disconnect the network connection.

When the user wants the terminal device to disconnect from the network, the user can switch the WLAN client application to the foreground and set the WLAN client application so that the WLAN client application sends an offline request to the Portal server, and the Portal server receives After the offline request, the terminal device will be disconnected from the network, and the terminal device will go offline. In addition, even if the terminal device performs illegal actions such as illegal shutdown, the WLAN client application will be forced to close, and the WLAN client application will be forced to After it is closed, the WLAN client application program will not be able to regularly send heartbeat packets to the Portal server. When the Portal server cannot receive the heartbeat packet sent by the terminal device through the WLAN client application program, the Portal server will think that the terminal device user does not want to send the heartbeat packet. The terminal device keeps the network connection. At this time, the Portal server disconnects the network connection of the terminal device, and the terminal device goes offline. In this way, the Portal server can disconnect the network connection of the terminal device in time when the terminal device is illegally shut down.

The Internet operating system (Internetwork Operation System, iOS for short) does not support WLAN client applications running in the background. After the WLAN client application is transferred to the background, it will be in a "sleeping" state. In order to ensure that the terminal device remains online after logging in to the portal server, the iOS system usually adopts the method of canceling the heartbeat packet, that is, after the terminal device logs in to the portal server, the portal server Keep the terminal device online until the terminal user logs out through the login application program. For a terminal device using the iOS system, when the user wants to disconnect from the network, the user can only disconnect the network connection by activating the "sleeping" WLAN client application in the background and sending an offline request to the Portal server.

However, in the iOS system, when the terminal device performs illegal actions such as illegal shutdown or the illegal closing of the WLAN client application, or the user has not used network functions for a long time, but forgets to log out from the WLAN client, even if the WLAN client application has been closed, the Portal server will still keep the terminal device online. The accuracy of the Portal server recording the online status of the terminal device is poor. precise.

Step 101, the WLAN client receives a login request message from a user.

Specifically, in one embodiment, the WLAN client is an application program on the terminal device. The user runs the WLAN client on the terminal device and operates the WLAN client. Through the operation of the WLAN client, the user The login request message of the user is sent to the WLAN client. For example, the user clicks the "connect to the network" function button on the WLAN client, and the user's login request message is sent to the WLAN client through this operation, and the WLAN client receives the login request message. Afterwards, an authentication request message is sent to the portal server, requesting the portal server to connect the terminal device to the network, so that the terminal device goes online.

Step 102, the WLAN client sends a delegation request message to the program server, the delegation request message includes: a preset online duration and the identifier of the terminal device, so that the program server can Sending a heartbeat packet to the portal server inwardly, where the heartbeat packet includes the terminal device identifier.

Specifically, the WLAN client sends a delegation request message to the program server (Provider). For example, in this embodiment, the delegation request message sent by the WLAN client to the program server includes the preset online duration and the set The identifier of the terminal device, the preset online duration is the preset duration for the terminal device user to keep the terminal online before sending the entrusting request message, and the duration may specifically be a time value, such as 1 hour, that is, the terminal device The user wishes to stay online for 1 hour. In other embodiments, the preset online duration can also be in other forms. The identifier of the terminal device is the identifier of the terminal device sending the delegation request message, and the program server learns the terminal device sending the delegation request message according to the received delegation request message. In one embodiment, an "online user form" is maintained on the program server, and the form is used to record the identification of the terminal device that is currently online. After the program server receives the delegation request message, it can also The identification of the terminal device contained in the message is added to this "Online User Form".

After receiving the delegation request message sent by the WLAN client, the program server sends a heartbeat packet to the portal (Portal) server within the preset online duration included in the delegation request message. In this embodiment, the portal server has a certain heartbeat time interval, and the program server sends a heartbeat packet to the portal server according to the heartbeat frequency of the portal server within the preset online duration, and the heartbeat packet includes the terminal The device ID of the device, so that the terminal device can remain online within the preset online duration, even if the user puts the WLAN client on the terminal device into the background "sleep", it will not affect the terminal device to stay online .

In this embodiment, the WLAN client receives the login request message from the terminal device, and sends a delegation request message to the program server, so that the program server sends a heartbeat packet to the portal server within the preset online time to maintain the The terminal device is online, so that the program server can maintain the online duration of the terminal device according to the preset online duration included in the commission request message sent by the WLAN client, so that the terminal device remains online within the preset online duration, and the portal server The online status of the terminal device can be judged according to the received heartbeat packet, which improves the accuracy of the portal server in judging the online status of the terminal device, thereby improving the accuracy of the portal server in calculating the online duration of the terminal device.

Fig. 2 is the flowchart of the second embodiment of the method for maintaining the heartbeat mechanism of the present invention. As shown in Fig. 2, the method for maintaining the heartbeat mechanism of the second embodiment includes:

Step 201, the program server receives a delegation request message from a WLAN client, where the delegation request message includes: a preset online duration and an identifier of a terminal device.

Specifically, the program server receives a delegation request message from the WLAN client, where the delegation request message includes: a preset online duration and an identifier of the terminal device, wherein the online duration is preset by the terminal device. In one implementation, an "online user form" is maintained on the program server, and the user form is used to record the identification of the terminal device that is currently online. After the program server receives the entrusting request message, it can also The identification of the terminal device included in the delegation request message is added to this "Online User Form".

Step 202, the program server sends a heartbeat packet to the portal server within the preset online duration, and the heartbeat packet includes the terminal device identifier.

Specifically, the program server sends a heartbeat packet to the portal server within the preset online duration included in the delegation request message, so as to maintain the online status of the terminal device.

In this embodiment, the program server receives the entrustment request message from the WLAN client, the entrustment request message includes: a preset online duration and the identifier of the terminal device, and the program server sends a request to the portal server within the preset online duration Send a heartbeat packet, the heartbeat packet includes the terminal device identifier, the WLAN client can send a heartbeat packet to the portal server through the entrusting program server to maintain the terminal user online within the preset online duration, and realize that the portal server can The heartbeat packet judges the online status of the terminal device, which improves the accuracy of the portal server in judging the online status of the terminal device, thereby further improving the accuracy of the portal server in calculating the online duration of the terminal device.

Figure 3 is a signaling flow chart of Embodiment 3 of the method for maintaining the heartbeat mechanism of the present invention. In Embodiment 3, the terminal device is an Apple mobile phone (iPhone), and the push server is an Apple Push Notification Service (APNs for short) as an example to describe in detail , as shown in Figure 3, the method specifically includes:

Step 301, the Apple mobile phone is initialized.

Specifically, when an iPhone is used for the first time, it usually needs to be initialized. For example, the initialization process can be as follows: the iPhone connects to APNs through the Secure Sockets Layer protocol (Secure Sockets Layer, SSL for short) and applies for registration with APNs, and APNs completes the registration of the iPhone Then generate the device token (DeviceToken) of the iPhone and return it to the iPhone.

Step 302, the WLAN client of the Apple mobile phone sends an authentication request message to the portal server, so that the Apple mobile phone is connected to the network.

Specifically, the user of the iPhone can send an authentication request message to the portal server by operating the relevant function button on the WLAN client of the iPhone. After the portal server passes the authentication request of the iPhone, the iPhone can access the WAN through the portal server.

Further, the user of the Apple mobile phone can also set the length of time that the WLAN client of the Apple mobile phone is expected to keep online, that is, set the online duration.

Step 303 , the WLAN client of the Apple mobile phone sends a delegation request message to the program server, and the delegation request message includes: a preset online duration and a device token identifier.

Specifically, before the WLAN client of the Apple mobile phone is switched to run in the background, the WLAN client can send a delegation request message to the program server in an automatic manner or a user-triggered manner, and the delegation request message includes: Online duration and the device token ID obtained in 301 above.

Step 304, the program server adds the device token identifier to the online user form.

Specifically, the program server adds the device token identifier included in the delegation request message to the online user form of the program server, and the online user form is used to record the device token identifier of the online terminal device currently maintained by the program server.

This step is optional, and in a specific implementation manner, this step may not be performed, and after step 303, step 305 is directly performed.

Step 305, the program server regularly sends the heartbeat packet of the Apple mobile phone to the portal server.

Specifically, according to the preset online duration set in the entrusting request message, the program server regularly sends heartbeat packets to the portal server within the preset online duration to keep the Apple mobile phone online. In an implementation manner, the program server sends a heartbeat packet to the portal server at a certain time interval, which is consistent with the time interval at which the portal server receives the heartbeat packet.

Step 306, the program server sends an arrival notification message to APNs.

Specifically, in one implementation, when the preset online duration of an Apple mobile phone is about to expire, the program server sends a notification message containing the token identifier of the Apple mobile phone device to APNs, and the time limit for the preset online duration to expire can be set in advance. The setting, for example, can be 15 seconds, that is, 15 seconds before the preset online duration of the Apple mobile phone arrives, the program server sends a notification message including the device token identifier of the Apple mobile phone to APNs.

Step 307, APNs pushes an arrival notification message to the WLAN client of the Apple mobile phone.

Specifically, after APNs receives the notification message containing the device token identification of the Apple mobile phone sent by the program server, it pushes an arrival notification message to the WLAN client of the Apple mobile phone identified by the device token. The arrival notification message is presented on the mobile phone, for example, the WLAN client may present the arrival notification message on the Apple mobile phone in the form of a message (Message).

Step 308, the Apple mobile phone user determines whether to continue online.

Specifically, after receiving the message presented by the WLAN client, the user of the Apple mobile phone knows that the online duration set this time is about to arrive. When the user sends a reply message to the WLAN client, wherein, the message is the first value indicating that the user wishes to remain online, in this case, return to step 303, and execute the process from step 303 to step 308 again, the message is the second value A value indicates that the user wishes to terminate online, in which case step 309 is performed. For example, the user replies to the message by selecting the "Activate" and "Ignore" buttons provided by the message, or ignores the message. If the user selects "Activate", it means that the Apple mobile phone user wishes to continue to be online. Correspondingly, return In step 303, the process from step 303 to step 308 is executed again; if "ignore" is selected or the message is ignored, it means that the user wishes to stop being online, and accordingly, step 309 is executed.

Specifically, the WLAN client receives a timely reply message from the user of the Apple mobile phone, and judges according to the reply message. If the reply message is the first value, that is, the reply message indicates that the user wishes to continue to stay online, step 303 is executed again, namely The WLAN client sends the delegation request message to the program server again, so as to perform subsequent steps 304, 305, 306 and 307 in sequence again, that is, if the program server receives the request from the WLAN client again The delegation request message continues to send the heartbeat packet to the portal server within the next preset online duration.

Step 309, the program server sends an offline request message to the portal server when the preset online time period ends.

Specifically, if the time-out reply message sent by the user is the second value, the reply message indicates that the user wishes to terminate online, and the program server does not receive another message from the WLAN client when the preset online time period ends. A delegation request message, for example, if no delegation request message from the WLAN client is received 5 seconds before the end of the preset online time, the program server sends the message to the portal server when the preset online time ends An offline request message, which includes the device token identifier of the Apple mobile phone. After the portal server receives the offline request message from the program server, the Apple mobile phone identified by the device token is disconnected from the WAN, and the program server After sending an offline request message to the portal server, the device token identifier of the Apple mobile phone can also be deleted from the "online user form".

Step 310, the portal server offlines the Apple mobile phone.

Specifically, the portal server disconnects the Apple mobile phone identified by the device token from the wide area network after receiving the logout request message from the program server.

Step 311, the portal server sends an offline success response to the program server.

Step 312, the program server sends a logout success message to APNs.

Specifically, after the program server receives the response from the portal server that the Apple mobile phone is successfully offline, it sends a successful offline message to APNs, and the successful offline message includes the device token identifier of the Apple mobile phone.

Step 313, APNs sends a logout success message to the WLAN client of the Apple mobile phone.

Specifically, APNs sends an offline success message to the WLAN client of the Apple mobile phone identified by the device token contained in the offline success message.

Step 314, the WLAN client of the Apple mobile phone ends the process.

The process ends after the WLAN client receives the offline success message.

After the above step 305, it may also include:

The WLAN client receives the first logout request message from the user.

Specifically, after the Apple mobile phone logs in to the WAN, the WLAN client can receive the logout request message sent by the user of the Apple mobile phone at any time within the preset time period set by the user. " button to send the first logout request message to the WLAN client.

The WLAN client sends a delete delegation request message to the program server.

Specifically, after receiving the first offline request message of the Apple mobile phone, the WLAN client sends a delete delegation request message to the program server to request the program server to stop sending the heartbeat packet of the Apple mobile phone to the portal server.

The program server sends an offline request message to the portal server.

Specifically, after receiving the deletion delegation request message from the WLAN client, the program server sends the Apple mobile phone offline request message to the portal server, so that the Apple mobile phone is disconnected from the wide area network.

The program server deletes the terminal device in the "online user form".

Specifically, the program server deletes the terminal identifier of the iPhone in the "online user form" after receiving the response from the portal server that the iPhone is successfully offline.

In this embodiment, the WLAN client receives the time-out notification message sent by the program server through the push server and forwards it to the terminal device, and continues to send the time-out notification message to the portal server according to the time-out reply message of the terminal device. The heartbeat packet maintains the terminal device online or performs an offline operation, and if the timed reply message is the first value, the WLAN client sends the delegation request message to the program server again, so that the program The server continues to send the heartbeat packet to the portal server within the next preset online duration, and if the timed reply message is the second value, the WLAN client end process, so that the program server Send an offline request message to the portal server when the preset online duration ends, the offline request message includes the terminal device token identifier, the portal server can judge the online status of the terminal device according to the received heartbeat packet, and improve This improves the accuracy of the portal server in judging the online status of the terminal equipment, and can further improve the accuracy of the Portal server in calculating the online duration of the terminal equipment.
