Background
With the rapid development of mobile communication networks and the popularization of mobile terminals such as smart phones, APPs are becoming more and more diversified. Many applications of real-time messages require real-time reception of push information from a server, and to achieve this, a long connection is typically used between the terminal and the server for communication.
Because the mobile network has the problems of NAT timeout and DHCP lease timeout, and particularly for the mobile network may have poor signals and instability, the long connection maintained between the mobile terminal and the server is not always valid, and in order to enable the mobile terminal to find that the connection has failed as early as possible, a heartbeat packet sending mechanism is usually adopted between the mobile terminal and the server for detecting to determine whether the connection is still in an available state.
When the mobile terminal and the server are communicated, the mobile terminal sends heartbeat data packets to the server, the server sends responses to the terminal, if the mobile terminal receives the responses, the connection is effective, and if the terminal receives the responses, the response is overtime, the connection is invalid, the terminal can disconnect the current connection and reestablish a new connection.
The prior art detection method mostly adopts a mode of sending heartbeat data packets at fixed time, namely, setting a fixed time interval (such as 3 minutes) to send the heartbeat data packets. In different network environments, the timeout duration is not fixed, and may be much longer than 3 minutes (e.g. 5 minutes), and this method causes unnecessary loss to the traffic and power of the mobile terminal due to the fixed detection interval, and the user experience effect is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
An embodiment of a method for dynamically adjusting a detection interval of a mobile terminal and a server comprises the following steps:
referring to fig. 1, the method for dynamically adjusting the detection interval of the mobile terminal and the server according to the present invention includes the following steps:
step S1, after the mobile terminal is determined to be in the detection state, the mobile terminal runs the application program to detect, on the basis of the initial detection interval duration, the heartbeat data packet is sent to the server, and if the detection is successful, the first detection duration is increased on the basis of each detection interval duration;
and step S2, if the detection fails, the detection time length is not increased, and the heartbeat data packet is sent continuously by using the current detection interval time length.
Step S3, if the continuous detection fails for the preset number of times, the mobile terminal determines that the detection interval has reached the timeout upper limit of the current network, and switches to the stable state, and uses the detection interval duration of the last detection success as the detection interval duration of the stable state.
In this embodiment, the mobile terminal application is in a detection state when it is just running, and at this time, the heartbeat data packet is sent from the initial detection interval duration (e.g. 3 minutes), and the detection interval duration is increased by 15 seconds after each success. And if the detection fails, the interval duration is not increased, the heartbeat data packet is continuously sent by using the current detection interval duration, after the continuous detection fails for 5 times, the current network timeout upper limit is considered to be reached, the state is switched to a stable state, and the detection interval duration successfully detected last time is used as the detection interval duration of the stable state.
When the application of the mobile terminal runs in a stable state, if the heartbeat data packet is continuously sent for 5 times, the mobile terminal enters a detection state again.
In this embodiment, when the mobile terminal runs the application program, the detection information of the corresponding last detection result is read according to the current network identifier, where the information includes the state and the detection interval where the current mobile terminal is detected.
The mobile terminal switches among an idle state, a detection state and a stable state in an operation period, and waits for network recovery if the current state is in the idle state; if the current state is in the detection state, sending a heartbeat data packet to the server, and continuously adjusting the detection interval duration; and if the current state is in a stable state, detecting and solidifying the heartbeat data packet with the optimal detection interval duration, and subsequently continuously sending the heartbeat data packet by using the detection interval.
When the mobile terminal operates in a detection state, the heartbeat data packet is sent according to the current detection interval duration, when the heartbeat data packet is sent successfully, the first detection duration is increased on the basis of the current detection interval duration, and the next heartbeat data packet sending process is started.
If the detection fails, the specific processing comprises:
if the detection failure times are less than the preset times, the detection interval duration is not increased, and the next heartbeat data packet sending process is started; if the detection failure times are larger than or equal to the preset times, the current detection interval is considered to reach the maximum overtime length of the network, at the moment, the mobile terminal is switched into a stable state, and the detection interval length of the last detection success is used as the detection interval length of the stable state.
When the mobile terminal operates in a stable state, the heartbeat data packet is sent according to the detection interval duration of the stable state, when the heartbeat data packet is sent successfully, the preset stable state duration is waited, and then the next heartbeat data packet sending process is started.
If the detection fails, the specific processing comprises:
if the detection failure times are less than the preset times, directly starting the next heartbeat data packet sending process; if the detection failure times are larger than or equal to the preset times, the network environment where the mobile terminal is located is considered to be changed, the detection interval time recorded in the last stable state is not used any more, and the mobile terminal is switched to the detection state to detect the maximum available detection interval time again.
In the running process of the application of the mobile terminal, when the network environment is switched, the identification of the current network is read, and the corresponding network detection result information is read according to the network identification, wherein the specific processing comprises the following steps: if the corresponding network detection result information is not read, directly converting to a detection state; and if the corresponding network detection result information exists, switching to an idle state, a detection state and a stable state according to the state of the network detection result information, and switching among the idle state, the detection state and the stable state in the application running period of the mobile terminal.
In this embodiment, probes are distinguished for each network individually, and the network identifier of each network is obtained through an API provided by the operating system. Specifically, since the timeout duration of each network may be inconsistent, each network needs to be separately detected, common mobile network environments include 2G, 3G, 4G, and 5G networks of china mobile, china unicom, and china telecom, each network has its own unique identifier, the application can be obtained through an API provided by an operating system, and wireless communication networks such as WIFI are used as network identifiers (e.g., WIFI) according to their names.
Specifically, the present invention sets the states of the mobile terminal applications to 3, as follows:
detecting state: in a state of continuously adjusting the detection interval.
And (3) steady state: and selecting an optimal detection interval, solidifying, and then continuously using the interval to send heartbeat data packets.
An idle state: the state when the network is unavailable, no probing is performed at this time, and no probing hop packet is sent.
Wherein the mobile terminal application is constantly switched between 3 states within the operation period.
In practical application, the invention firstly sets relevant variables as follows:
minHeartbeat is a minimum detection interval duration (initial detection interval duration) of 3 minutes;
maxHeartbeat: the maximum detection interval duration is 10 minutes;
stableHeartbeat: a detection interval duration of a steady state;
prevHeartbeat: the interval duration of the last successful detection;
currHeartbeat: the interval duration currently being probed.
As shown in fig. 2, when the mobile terminal application is started, the detection information of the corresponding last detection result is read according to the current network identifier, including the state where the detection is located, the detection interval, and the like. If the current state is in the detection process of switching to the detection state, if the current state is in the detection process of switching to the stable state, and if the current state is in the idle state, waiting for the network to recover.
As shown in fig. 3, when the mobile terminal application is in the detection state, the heartbeat packet is sent according to the currHeartbeat interval, when the sending is successful, the currHeartbeat interval is increased by 15 seconds, and then the next heartbeat packet sending flow is started; if the detection fails, the detection is processed in two cases:
1) and if the detection failure times are less than 5, not increasing the interval duration, and then starting the next heartbeat data packet sending process.
2) If the detection failure times are more than or equal to 5 times, the maximum overtime time of the network is considered to be reached currently, the network is switched into a stable state, and the time length of the last detection success is used as the detection interval time length (stepablehertpeak) of the stable state.
In practical tests, as long as the detection interval duration exceeds the maximum timeout duration of the network, detection can not be successfully performed at one time basically. However, in some special cases, even if the timeout period is not reached, a failure is detected, for example, an environment where the network suddenly deteriorates such as an elevator is entered, so that the upper failure limit is set to 5 times in order to reduce similar errors, which means that a plurality of trials are performed, and this is an empirical value for integrating the actual measurement effect.
As shown in fig. 4, when the application of the mobile terminal is in a stable state, the heartbeat data packet is sent according to the steableHeartbeat interval, when the sending is successful, the heartbeat data packet is waited for the duration of the steableHeartbeat interval, and then the next heartbeat data packet sending process is started; if the detection fails, the detection is processed in two cases:
1) if the detection failure times are less than 5, directly starting the next heartbeat data packet sending process;
2) if the detection failure times are more than or equal to 5, the network environment where the current network environment is located is considered to be changed, the interval duration recorded in the last stable state is possibly not applicable any more, and then the network environment is switched into the detection state, and the maximum available interval duration is detected again.
Similarly, the upper limit of the number of failures is set to 5, mainly to eliminate errors. In practical tests, detection can be recovered basically within 3 times under the condition of excluding the change of the network environment, and if continuous detection fails for 5 times, the network environment can be determined to have changed at the moment and needs to be detected again.
As shown in fig. 5, when the mobile terminal is in an operating process, a network change may cause a state switch, and no matter what detection state the mobile terminal is in, when the network is switched, the currently operating detection may be interrupted to perform the state switch. When the network is switched, firstly reading the identifier of the current network, then reading the corresponding network detection result information according to the network identifier, and processing according to the following conditions:
1) and if the corresponding network detection result information is not read, directly converting to a detection state.
2) And if the corresponding network detection result information exists, jumping to an idle state, a detection state or a stable state according to the state of the information.
Therefore, the invention realizes the adjustment of the detection interval according to the requirement, reduces the sending of heartbeat data packets, and has the following beneficial effects:
1. the method can adapt to mobile network environments of different operators and different regions.
2. The service life of the mobile terminal battery can be prolonged, so that the resource utilization rate can be improved, and the user experience can be improved.
3. The method avoids frequent calling of the terminal, and can reduce the network flow usage of the mobile terminal, thereby saving wireless channel resources and reducing the energy consumption of the mobile terminal.
4. The interaction times between the central server and the terminal are greatly reduced, and the processing pressure and the burden of the central server are reduced.
