## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of International Application No. PCT/CN2013/074797, filed on Apr. 26, 2013, which is hereby incorporated by reference in its entirety.


TECHNICAL FIELD
The present invention relates to the communications field, and in particular, to a method and an apparatus for controlling sending of a heartbeat signal.
BACKGROUND
With the development of services, such as Internet, mobile network, digital television, and mobile multimedia broadcasting services, Push, which emerged earliest as a push instruction in the computer programming language, has developed to be a client/server mechanism-based technology in which a server proactively sends information to a client. Internet Protocol (IP) Push refers to an Hypertext Transfer Protocol (HTTP)-based technology in which a server pushes a message to a mobile device through an IP network.
To enable a server to push information to a mobile device in real time, a connection is established between the mobile device and the server. If there is no push message exchange for a long time, the connection may be disconnected, and consequently, the push message cannot be pushed to the mobile device in time. Therefore, to keep stability of the connection, the mobile device needs to send a heartbeat signal to the server at intervals, so as to keep the connection in an active state. In the prior art, after a connection is established between a mobile device and a server, the mobile device sends a heartbeat signal to the server at a fixed time interval, that is, the mobile device sends the heartbeat signal to the server at a fixed frequency. If a time interval for sending the heartbeat signal is too long, the connection may be disconnected due to interference, such as network quality or a firewall, causing that a push message cannot be pushed by the server to the mobile device in time. If the time interval for sending the heartbeat signal is too short, the mobile device needs to enable a network constantly, so as to send the heartbeat signal to the server, which increases battery power consumption of the mobile device and increases network traffic of the mobile device.

DETAILED DESCRIPTION
To make the objectives, technical solutions, and advantages of the present invention clearer and more comprehensible, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments.
According to a method and an apparatus for controlling sending of a heartbeat signal provided by embodiments of the present invention, a push client acquires a target push delay corresponding to all target applications; the push client sends the target push delay to a push server; the push server receives the target push delay sent by the push client and corresponding to all the target applications; the push server acquires a first heartbeat signal control time corresponding to the target push delay; the push server sends the first heartbeat signal control time to the push client; the push client receives the first heartbeat signal control time; and the push client sends a heartbeat signal to the push server at an interval of the first heartbeat signal control time. A heartbeat signal control time can be adjusted according to a target application, so that the push client can send a heartbeat signal to the push server at an interval of the heartbeat signal control time, which ensures stability of a Push connection, thereby further improving timeliness of push message pushing and enhancing user experience. Furthermore, because a length of the heartbeat signal control time can be adjusted according to the target application, unnecessary power consumption and network data traffic can be reduced.
The push server refers to a server that can provide a Push service. The Push server is connected to the Push client through an IP network, for example, a Transmission Control Protocol (TCP) connection may be established between the Push client and the Push server. To keep stability of the connection, the Push client sends a heartbeat signal to the Push server at intervals, to keep the connection in an active state and keep the stability of the Push connection. The Push server may push a message to the Push client at any time by using the Push connection.
The push client refers to a terminal that subscribes to a Push service during network registration, such as a mobile phone, a tablet computer, a digital television terminal, or a set top box. The Push client includes a Push proxy and at least one target application. The target application may be an application program that is included in the push client and that successfully registers application information with the Push proxy, where the registered application information includes a target application name and a push-acceptable signal delay. The target application may be, for example, a telephone application of a mobile phone that successfully registers application information with the Push proxy, a game application of a tablet computer that successfully registers application information with the Push proxy, or a finance application of a digital television that successfully registers application information with the Push proxy, that is, the target application is an application program that can receive a Push message. The Push proxy is a communication proxy that is used as a proxy for the target application to send a target push delay, a heartbeat signal, or the like, to the push server, or is used as a proxy for the target application to receive a push message, a target push delay, or the like, from the push server.
After the connection is established between the Push server and the Push client, the application program needs to apply to the Push server for registration, and after the registration succeeds, the Push server may receive a heartbeat signal sent by the Push client, or send a push message to the target application. The target application applies to the Push server for a push target address identifier, where the push target address identifier is a unique identifier of a Push target address and is used to identify to which application of a specific device of the client a message is pushed. Steps for the application program to apply to the Push server for registration are as follows.
The application program sends registration application information to the Push proxy, where the registration application information includes an application program name and a push-acceptable heartbeat signal delay, and the push-acceptable heartbeat signal delay is a time period, such as 30 seconds, 2400 seconds, or 3600 seconds.
After receiving the registration application information, the Push proxy sends corresponding registration request information to the Push server, where the registration request information includes a unique device identifier, the application program name, and the push-acceptable heartbeat signal delay, where the unique device identifier is a device code used to identify a device of the Push client, for example, an International Mobile Equipment Identity (IMEI), which is a globally unique electronic serial number granted to each mobile phone after assembling is completed.
After receiving the registration request information, the Push server generates a corresponding push target address identifier, and returns the generated push target address identifier to the Push proxy.
After receiving the push target address identifier returned by the Push server, the Push proxy returns the push target address identifier to the application program, where the application program that successfully registers the application information with the Push proxy is the target application.
Referring to FIG. 1, FIG. 1 is a schematic structural diagram of an apparatus for controlling sending of a heartbeat signal according to an embodiment of the present invention. The apparatus for controlling sending of a heartbeat signal may be a push client. As shown in FIG. 1, the apparatus for controlling sending of a heartbeat signal at least includes a target push delay acquiring module 101, a target push delay sending module 102, a first receiving module 103, and a first heartbeat-signal sending module 104.
The target push delay acquiring module 101 is configured to acquire a target push delay corresponding to all target applications. In a specific implementation, when a Push connection is established or a target application is installed or uninstalled, the target push delay acquiring module 101 in the Push client acquires the target push delay corresponding to all the target applications. Further, optionally, the target push delay acquiring module 101 may include a first acquiring unit and a second acquiring unit, where the first acquiring unit is configured to, when a quantity of all the target applications is one, acquire a push delay of the target application, and use the push delay of the target application as the target push delay; and the second acquiring unit is configured to, when a quantity of all the target applications is at least two, acquire push delays of all the target applications, and use a shortest push delay in all the push delays as the target push delay.
Optionally, after a push delay attribute parameter of a target application is read, a push delay of the target application is obtained, that is, each target application corresponds to one push delay attribute parameter, and each target application corresponds to one push delay. Push delay attribute parameters of all the target applications in the push client are read. If there is only one target application, the first acquiring unit acquires a push delay of the target application, and uses the acquired push delay of the target application as the target push delay; if there are multiple target applications, the second acquiring unit acquires push delays of all the target applications, and performs comparison to obtain a shortest push delay as the target push delay.
The target application may write the push delay attribute parameter into a static configuration file, where the push delay attribute parameter indicates a heartbeat signal delay range acceptable to the target application, and may be an editable time length in seconds. For example, a push delay attribute parameter of 60 seconds can be written into an ANDROID device by using the following statements, that is, by adding the following content to a manifest.xml file in an application package in the ANDROID device.















<meta-data



android:name=“PushDeviateSecond”



android:value=“60” >



</meta-data>










A PushDeviateSecond attribute value in a configuration file of at least one target application is read to obtain a push delay of the target application. For example, in an ANDROID device, a Push client acquires, through an operating system interface, a PushDeviateSecond attribute value of meta-data in a configuration file of a target application.
When there are at least two target applications, push delays of all the target applications are acquired, and a shortest push delay in all the push delays is used as the target push delay. For example, push delays that are obtained by reading push delay attribute parameters configured by four target applications and that correspond to all the target applications are as follows: a push delay of a target application A is 30 seconds, a push delay of a target application B is 90 seconds, a push delay of a target application C is 300 seconds, and a push delay of a target application D is 3600 seconds; then, a shortest push delay, obtained by comparison, is 30 seconds, and therefore, a target push delay acquired by the target push delay acquiring module 101 is 30 seconds.
The target push delay sending module 102 is configured to send the target push delay acquired by the target push delay acquiring module 101 to a push server. In a specific implementation, the target push delay acquired by the target push delay acquiring module 101 is sent to the Push server, and an information format of the target push delay is as follows.

The first receiving module 103 is configured to receive a corresponding first heartbeat signal control time that is returned by the push server according to the received target push delay sent by the target push delay sending module 102.
The first heartbeat-signal sending module 104 is configured to send a heartbeat signal to the push server at an interval of the first heartbeat signal control time according to the first heartbeat signal control time received by the first receiving module 103. In a specific implementation, the first heartbeat-signal sending module 104 sends the heartbeat signal to the push server at an interval of the first heartbeat signal control time to maintain a connection; for example, the first heartbeat-signal sending module 104 sends, according to a received first heartbeat signal control time of 60 seconds, a heartbeat signal to the push server at an interval of 60 seconds.
Further, optionally, the apparatus for controlling sending of a heartbeat signal in this embodiment of the present invention may further include a sending failure rate reporting module 105, a second receiving module 106, and a second heartbeat-signal sending module 107.
The sending failure rate reporting module 105 is configured to report a sending failure rate to the push server when detecting that the heartbeat signal fails to be sent. In a specific implementation, when detecting that the heartbeat signal fails to be sent, the push client reports the sending failure rate to the push server, where the sending failure rate is a quantity of heartbeat signal sending failures within a preset time. In a heartbeat signal sending process, heartbeat signal sending may fail if the heartbeat signal is lost or times out, or heartbeat signal sending may also fail if a connection is disconnected due to poor network quality. When the heartbeat signal sending fails, the push client may receive a heartbeat signal sending failure response, and further detects the heartbeat signal sending failure. For example, a format of the sending failure rate reported to the Push server is as follows.

The second receiving module 106 is configured to receive a second heartbeat signal control time that is returned by the push server according to the sending failure rate reported by the sending failure rate reporting module 105 and the target push delay sent by the target push delay sending module 102, where the second heartbeat signal control time is shorter than the first heartbeat signal control time. The push server returns the acquired second heartbeat signal control time to the push client, and the second receiving module 106 of the push client receives the second heartbeat signal control time returned by the push server.
The second heartbeat-signal sending module 107 is configured to send a heartbeat signal to the push server at an interval of the second heartbeat signal control time according to the second heartbeat signal control time received by the second receiving module 106. In a specific implementation, the second heartbeat-signal sending module 107 sends the heartbeat signal to the push server at an interval of the second heartbeat signal control time to maintain a connection. For example, the second heartbeat-signal sending module 107 sends, according to a received second heartbeat signal control time of 45 seconds, a heartbeat signal to the Push server at an interval of 45 seconds. The second heartbeat signal control time is a heartbeat signal control time that is re-adjusted after a previous heartbeat signal sending failure, thereby maintaining a Push connection and ensuring stability of the connection when heartbeat signal sending fails due to heartbeat signal loss or timeout, poor network quality, or the like.
The apparatus for controlling sending of a heartbeat signal provided by this embodiment of the present invention may determine a first heartbeat signal control time according to an acquired target push delay corresponding to all target applications, and the first heartbeat signal control time may be adjusted according to a target application, so that a push client can send a heartbeat signal to a push server at an interval of the first heartbeat signal control time; and when heartbeat signal sending fails due to network quality, signal loss, or the like, the push client may further send a heartbeat signal to the Push server according to a received second heartbeat signal control time returned by the push server; further, a heartbeat signal control time may be adjusted according to network quality or the like, thereby ensuring stability of a Push connection, and further improving timeliness of push message pushing, enhancing user experience, and effectively reducing power consumption and network data traffic.
Referring to FIG. 2, FIG. 2 is a schematic structural diagram of another apparatus for controlling sending of a heartbeat signal according to an embodiment of the present invention. The apparatus for controlling sending of a heartbeat signal may be a push server. As shown in FIG. 2, the apparatus for controlling sending of a heartbeat signal at least includes a target push delay receiving module 201, a first-heartbeat-signal-control-time acquiring module 202, a first sending module 203, and a first heartbeat-signal receiving module 204.
The target push delay receiving module 201 is configured to receive a target push delay sent by a push client and corresponding to all target applications. In a specific implementation, the target push delay receiving module 201 receives the target push delay sent by the push client and corresponding to all the target applications.
The first-heartbeat-signal-control-time acquiring module 202 is configured to acquire a first heartbeat signal control time corresponding to the target push delay received by the target push delay receiving module 201. In a specific implementation, when the first-heartbeat-signal-control-time acquiring module 202 of the push server acquires the first heartbeat signal control time corresponding to the target push delay, the first-heartbeat-signal-control-time acquiring module 202 is configured to acquire the first heartbeat signal control time according to a network standard, a push success rate, and the target push delay, where the first heartbeat signal control time is a longest heartbeat signal control time, corresponding to the target push delay, in a current network standard and when a preset push success rate is met.
The push success rate is statistical data that is pre-collected on different target applications by the push server in different network standards, where the data corresponds to a push delay and a heartbeat signal control time of a target application. For example, statistical data in the push server may be a chart, where, in this chart, a coordinate system is established by using the push delay and the heartbeat signal control time of the target application as a horizontal axis and a vertical axis respectively, and a corresponding coordinate point is the push success rate. When receiving the target push delay, the push server finds a corresponding longest heartbeat signal control time in the coordinate system according to the target push delay and a preset push success rate, and acquires the heartbeat signal control time as the first heartbeat signal control time. For example, a push delay of a target application A is 30 seconds, a push delay of a target application B is 45 seconds, a push delay of a target application C is 60 seconds, a target push delay corresponding to the target applications A, B, and C is 30 seconds, and a preset push success rate is 99.9 percent (%), a longest heartbeat signal control time corresponding to the push delay of 30 seconds and the push success rate of 99.9% is searched for in the chart, and the longest heartbeat signal control time of 60 seconds is found, and then, 60 seconds are determined as the first heartbeat signal control time.
The first sending module 203 is configured to send the first heartbeat signal control time acquired by the first-heartbeat-signal-control-time acquiring module 202 to the push client. In a specific implementation, the first sending module 203 of the push server sends the first heartbeat signal control time acquired by the first-heartbeat-signal-control-time acquiring module 202 to the push client. For example, a format of the first heartbeat signal control time sent to the push client is as follows.

In a specific implementation, after receiving the first heartbeat signal control time sent by the first sending module 203, the push client sends the heartbeat signal to the push server at an interval of the first heartbeat signal control time, and the push server receives the heartbeat signal sent by the push client, so as to maintain a Push connection.
Further, optionally, the apparatus for controlling sending of a heartbeat signal in this embodiment of the present invention may further include a sending failure rate receiving module 205, a second-heartbeat-signal-control-time acquiring module 206, a second sending module 207, and a second heartbeat-signal receiving module 208.
The sending failure rate receiving module 205 is configured to receive a sending failure rate that is reported by the push client after detecting that the heartbeat signal fails to be sent. In a specific implementation, when detecting that the heartbeat signal fails to be sent, the push client reports the sending failure rate to the Push server, and the push server receives the sending failure rate. In a heartbeat signal sending process, heartbeat signal sending may fail if the heartbeat signal is lost or times out, or heartbeat signal sending may also fail if a connection is disconnected due to poor network quality. When the heartbeat signal sending fails, the push client may receive a heartbeat signal sending failure response.
The second-heartbeat-signal-control-time acquiring module 206 is configured to acquire a second heartbeat signal control time that corresponds to the sending failure rate received by the sending failure rate receiving module 205 and the target push delay received by the target push delay receiving module 201. In a specific implementation, when the second-heartbeat-signal-control-time acquiring module 206 acquires the second heartbeat signal control time that corresponds to the sending failure rate and the target push delay, the second-heartbeat-signal-control-time acquiring module 206 is configured to acquire the second heartbeat signal control time according to a network standard, a push success rate, the sending failure rate, and the target push delay, where the second heartbeat signal control time is a longest heartbeat signal control time, corresponding to the sending failure rate and the target push delay, in a current network standard and when a preset push success rate is met.
The push success rate is statistical data that is pre-collected on different target applications by the push server in different network standards, where the data corresponds to a push delay and a heartbeat signal control time of a target application, and may be recorded and measured in a form of a chart. For example, for statistical data in the push server in the case of poor network quality, a coordinate system is established by using the push delay and the heartbeat signal control time of the target application as a horizontal axis and a vertical axis respectively, and a corresponding coordinate point is the push success rate. When receiving the target push delay, the push server finds a corresponding longest heartbeat signal control time in the coordinate system according to the target push delay and the preset push success rate; combined with the sending failure rate, multiplies the found heartbeat signal control time by a proportionality coefficient to obtain the second heartbeat signal control time, where the proportionality coefficient is a preset proportionality coefficient corresponding to the sending failure rate, and a correspondence is as follows: a higher sending failure rate indicates a lower preset proportionality coefficient, and a lower sending failure rate indicates a higher preset proportionality coefficient; and multiplies the found heartbeat signal control time by the proportionality coefficient to obtain the second heartbeat signal control time, where the second heartbeat signal control time is shorter than the first heartbeat signal control time. For example, a push delay of a target application A is 30 seconds, a push delay of a target application B is 45 seconds, a push delay of a target application C is 60 seconds, a target push delay is 30 seconds, a preset push success rate is 99.9%, a corresponding first heartbeat signal control time found in the chart is 40 seconds, a received sending failure rate is 5%, and a corresponding preset proportionality coefficient is 3⁄4; then, a second heartbeat signal control time is: 40*3⁄4=30 seconds.
It should be noted that this embodiment of the present invention does not limit a specific correspondence between the sending failure rate and the proportionality coefficient; a form of statistical data in the case of poor network quality and a form of statistical data in the case of normal network quality may be the same, but specific numeric values may be different; the form of the statistical data is not limited to a chart; and the statistical data may be updated periodically according to an actual situation.
The second sending module 207 is configured to send the second heartbeat signal control time acquired by the second-heartbeat-signal-control-time acquiring module 206 to the push client, where the second heartbeat signal control time is shorter than the first heartbeat signal control time.

The second heartbeat-signal receiving module 208 is configured to receive a heartbeat signal that is sent by the push client at an interval of the second heartbeat signal control time according to the received second heartbeat signal control time sent by the second sending module 207. In a specific implementation, the second heartbeat-signal receiving module 208 receives the heartbeat signal that is sent by the push client at an interval of the second heartbeat signal control time, so as to maintain a connection, where the second heartbeat signal control time is a heartbeat signal control time that is re-adjusted after a previous heartbeat signal sending failure, thereby maintaining a Push connection and ensuring stability of the connection when heartbeat signal sending fails due to heartbeat signal loss or timeout, poor network quality, or the like.

Referring to FIG. 3, FIG. 3 is a schematic structural diagram of a system for controlling sending of a heartbeat signal according to an embodiment of the present invention. As shown in FIG. 3, the system includes a push client 1 and a push server 2, where the push client 1 and the push server 2 are connected through an IP network; the push client refers to a terminal that subscribes to a Push service during network registration, for example, a device such as a mobile phone, a tablet computer, a digital television terminal, a set top box, or the like, and the push client includes a Push proxy and at least one target application, where the target application may be, for example, a telephone application of a mobile phone, a game application of a tablet computer, or a finance application of a digital television; each device may have one Push proxy and at least one target application; and the push client may include at least one device.
The push client 1, such as the apparatus described in the foregoing embodiment corresponding to FIG. 1, is configured to acquire a target push delay corresponding to all target applications; send the target push delay to the push server 2; receive a first heartbeat signal control time sent by the push server and corresponding to the target push delay; and send a heartbeat signal to the push server at an interval of the first heartbeat signal control time.
The push server 2, such as the apparatus described in the foregoing embodiment corresponding to FIG. 2, is configured to receive the target push delay sent by the push client 1 and corresponding to all the target applications; acquire the first heartbeat signal control time corresponding to the target push delay; send the first heartbeat signal control time to the push client; and receive the heartbeat signal sent by the push client at an interval of the first heartbeat signal control time.
The following illustrates a specific implementation of a method for controlling sending of a heartbeat signal provided by an embodiment of the present invention.
FIG. 4 is a flowchart of the method for controlling sending of a heartbeat signal according to this embodiment of the present invention. As shown in the figure, the method for controlling sending of a heartbeat signal at least includes the following steps.
Step S401. A push client acquires a target push delay corresponding to all target applications. In a specific implementation, when a Push connection is established or a target application is installed or uninstalled, the Push client acquires the target push delay corresponding to all the target applications, where the acquiring a target push delay corresponding to all target applications may include, if a quantity of all the target applications is one, acquiring a push delay of the target application, and using the push delay of the target application as the target push delay; or if a quantity of all the target applications is at least two, acquiring push delays of all the target applications, and using a shortest push delay in all the push delays as the target push delay.
Optionally, after a push delay attribute parameter of a target application is read, a push delay of the target application is obtained, that is, each target application corresponds to one push delay attribute parameter, and each target application corresponds to one push delay. Push delay attribute parameters of all the target applications in the push client are read. If there is only one target application, a push delay of the target application is acquired, and the acquired push delay of the target application is used as the target push delay; if there are multiple target applications, push delays of all the target applications are acquired, and comparison is performed to obtain a shortest push delay as the target push delay.
The target application may write the push delay attribute parameter into a static configuration file, where the push delay attribute parameter indicates a heartbeat signal delay range acceptable to the target application, and may be an editable time length in seconds. For example, a push delay attribute parameter of 60 seconds can be written into an ANDROID device by using the following statements, that is, by adding the following content to a manifest.xml file in an application package in the ANDROID device.















<meta-data



android:name=“PushDeviateSecond”



android:value=“60” >



</meta-data>










A push delay attribute parameter configured by at least one target application is read to obtain a push delay of the target application, that is, a PushDeviateSecond attribute value in a configuration file of the at least one target application is read. For example, in the ANDROID device, the Push client acquires the PushDeviateSecond attribute value of meta-data in the configuration file of the target application by using an operating system interface.
When there are at least two target applications, push delays of all the target applications are acquired, and a shortest push delay in all the push delays is used as the target push delay. For example, push delays that are obtained by reading push delay attribute parameters configured by four target applications and that correspond to all the target applications are as follows: a push delay of a target application A is 30 seconds, a push delay of a target application B is 90 seconds, a push delay of a target application C is 300 seconds, and a push delay of a target application D is 3600 seconds; then, a shortest push delay, obtained by comparison, is 30 seconds, and therefore, an acquired target push delay is 30 seconds.
Step S402. The push client sends the target push delay to a push server.
Step S403. The push server receives the target push delay sent by the push client.
Step S404. The push server acquires a first heartbeat signal control time corresponding to the target push delay. In a specific implementation, the acquiring a first heartbeat signal control time corresponding to the target push delay may include acquiring the first heartbeat signal control time according to a network standard, a push success rate, and the target push delay, where the first heartbeat signal control time is a longest heartbeat signal control time, corresponding to the target push delay, in a current network standard and when a preset push success rate is met.
The push success rate is statistical data that is pre-collected on different target applications by the push server in different network standards, where the data corresponds to a push delay and a heartbeat signal control time of a target application. For example, statistical data in the push server may be a chart, where, in this chart, a coordinate system is established by using the push delay and the heartbeat signal control time of the target application as a horizontal axis and a vertical axis respectively, and a corresponding coordinate point is the push success rate. When receiving the target push delay, the push server finds a corresponding longest heartbeat signal control time in the coordinate system according to the target push delay and a preset push success rate, and acquires the heartbeat signal control time as the first heartbeat signal control time. For example, a push delay of a target application A is 30 seconds, a push delay of a target application B is 45 seconds, a push delay of a target application C is 60 seconds, a target push delay corresponding to the target applications A, B, and C is 30 seconds, and a preset push success rate is 99.9%, a longest heartbeat signal control time corresponding to the push delay of 30 seconds and the push success rate of 99.9% is searched for in the chart, and the longest heartbeat signal control time of 60 seconds is found, and then, 60 seconds are determined as the first heartbeat signal control time.
Step S405. The push server sends the first heartbeat signal control time to the push client.
Step S406. The push client receives the first heartbeat signal control time returned by the push server.
Step S407. The push client sends a heartbeat signal to the push server at an interval of the first heartbeat signal control time. In a specific implementation, the heartbeat signal is sent to the push server at an interval of the first heartbeat signal control time, so as to maintain a connection. For example, according to a received first heartbeat signal control time of 60 seconds, a heartbeat signal is sent to the Push server at an interval of 60 seconds.
Step S408. Receive the heartbeat signal that is sent by the push client at an interval of the first heartbeat signal control time.
Step S409. If it is detected that the heartbeat signal fails to be sent, report a sending failure rate to the push server. In a specific implementation, in a heartbeat signal sending process, heartbeat signal sending may fail if the heartbeat signal is lost or times out, or heartbeat signal sending may also fail if a connection is disconnected due to poor network quality. When the heartbeat signal sending fails, the push client may receive a heartbeat signal sending failure response, and further detects the heartbeat signal sending failure.
Step S410. The push server acquires a second heartbeat signal control time that corresponds to the sending failure rate and the target push delay. In a specific implementation, the acquiring a second heartbeat signal control time that corresponds to the sending failure rate and the target push delay may include acquiring the second heartbeat signal control time according to a network standard, a push success rate, the sending failure rate, and the target push delay, where the second heartbeat signal control time is a longest heartbeat signal control time, corresponding to the sending failure rate and the target push delay, in a current network standard and when a preset push success rate is met.
The push success rate is statistical data that is pre-collected on different target applications by the push server in different network standards, where the data corresponds to a push delay and a heartbeat signal control time of a target application, and may be recorded and measured in a form of a chart. For example, for statistical data in the push server in the case of poor network quality, a coordinate system is established by using the push delay and the heartbeat signal control time of the target application as a horizontal axis and a vertical axis respectively, and a corresponding coordinate point is the push success rate. When receiving the target push delay, the push server finds a corresponding longest heartbeat signal control time in the coordinate system according to the target push delay and the preset push success rate; combined with the sending failure rate, multiplies the found heartbeat signal control time by a proportionality coefficient, where the proportionality coefficient is a preset proportionality coefficient corresponding to the sending failure rate, and a correspondence is as follows: a higher sending failure rate indicates a lower preset proportionality coefficient, and a lower sending failure rate indicates a higher preset proportionality coefficient; and multiplies the found heartbeat signal control time by the proportionality coefficient to obtain the second heartbeat signal control time, where the second heartbeat signal control time is shorter than the first heartbeat signal control time. For example, a push delay of a target application A is 30 seconds, a push delay of a target application B is 45 seconds, a push delay of a target application C is 60 seconds, a target push delay is 30 seconds, a preset push success rate is 99.9%, a corresponding first heartbeat signal control time found in the chart is 40 seconds, a received sending failure rate is 5%, and a corresponding preset proportionality coefficient is 3⁄4; then, a second heartbeat signal control time is: 40*3/4=30 seconds.
It should be noted that this embodiment of the present invention does not limit a specific correspondence between the sending failure rate and the proportionality coefficient; a form of statistical data in the case of poor network quality and a form of statistical data in the case of normal network quality may be the same, but specific numeric values may be different; the form of the statistical data is not limited to a chart; and the statistical data may be updated periodically according to an actual situation.
Step S411. The push server sends the second heartbeat signal control time to the push client, where the second heartbeat signal control time is shorter than the first heartbeat signal control time.
Step S412. The push client receives the second heartbeat signal control time returned by the push server.
Step S413. The push client sends a heartbeat signal to the push server at an interval of the second heartbeat signal control time.
Step S414. The push server receives the heartbeat signal that is sent by the push client at an interval of the second heartbeat signal control time. In a specific implementation, the heartbeat signal that is sent by the push client at an interval of the second heartbeat signal control time is received, so as to maintain a connection, where the second heartbeat signal control time is a heartbeat signal control time that is re-adjusted after a previous heartbeat signal sending failure, thereby maintaining a Push connection and ensuring stability of the connection when heartbeat signal sending fails due to heartbeat signal loss or timeout, poor network quality, or the like.
According to the method for controlling sending of a heartbeat signal provided by this embodiment of the present invention, a first heartbeat signal control time may be determined according to an acquired target push delay corresponding to all target applications, and the first heartbeat signal control time may be adjusted according to a target application, so that a push client can send a heartbeat signal to a push server at an interval of the first heartbeat signal control time; and when heartbeat signal sending fails due to network quality, signal loss, or the like, the push client may further send a heartbeat signal to the Push server according to a received second heartbeat signal control time returned by the push server; further, a heartbeat signal control time may be adjusted according to network quality, or the like, thereby ensuring stability of a Push connection, and further improving timeliness of push message pushing, enhancing user experience, and effectively reducing power consumption and network data traffic.
