2. Under the condition that the client and the server are in the normal link state, the method and the device further monitor the running state change and the network type change of the client in real time to obtain the current running state and the current network type of the client, so that different working modes are respectively adopted to adjust the trigger interval period, and then the working state of the client is adjusted, so that the link keep-alive mode is more reasonable, and flow waste and electric quantity consumption are reduced.
3. The method and the device further distinguish the foreground and background processing of the client, and the client still adopts a fixed time interval to send the keep-alive data packet when in a foreground running state, so that the user experience is ensured; and in the background running state, the method and the device can detect the longest trigger interval period in the current network environment in different modes according to different network types aiming at the situation that the client does not actively perform data interaction any more, so that not only can the method and the device reduce flow waste and electric quantity consumption, but also the link unavailability caused by the recovery of network resources by operators is avoided.

Fig. 1 is a flowchart of a method for optimizing keep-alive of a client communication link according to a first embodiment of the invention. It should be noted that, if there are substantially the same results, the method of the present invention is not limited to the flow sequence shown in fig. 1. As shown in fig. 1, the method for optimizing the keep-alive of the communication link of the client comprises the following steps:
s1, acquiring a current network type connected with a client, searching a preset threshold time corresponding to the current network type in a preset keep-alive time threshold information table according to the current network type, and taking the searched preset threshold time as a keep-alive time threshold of the client.
In actual operation, when the threshold time is set, the threshold time of the WIFI network may be 2 seconds, the threshold time of the operator network may be 5 seconds, and the preset threshold time and/or the keep-alive time threshold may be recorded into the keep-alive time threshold information table, and preferably, the step further includes:
when the communication connection with the server is detected to be established, monitoring the network type of the client connection in real time; if the network type connected with the client is monitored to be changed, acquiring a preset threshold time corresponding to the current network type, and updating the keep-alive time threshold of the client according to the preset threshold time.
In this step, after the client is started or after the client is disconnected from the server, the client establishes a communication connection with the server, such as a Socket communication long link, while the client starts to monitor what type of network connection the client is in, and after the monitoring is started, the stand-up obtains the type of network currently used by the client (for example, mobile app).
The network types of the client include: a wireless network, a WIFI network, and an operator network, wherein the operator network includes a plurality of types, such as a GPRS network, an EDGE network, a WCDMA network, a CDMA network, a LET network, and the like.
In the present application, the change of the client network type refers to that the client is transferred from one network connection state to another network connection state, for example, the client is transferred from a no-network connection to a network connection, or the client is transferred from an operator network to a WIFI network, etc.
S2, acquiring the current running state of the client, searching the preset interval duration corresponding to the current running state in a preset trigger interval period information table according to the current running state, and taking the searched preset interval duration as the trigger interval period of the client.
Preferably, the step further comprises: when the communication connection with the server is detected to be established, monitoring the running state of the client in real time; if the running state is monitored to change, acquiring a preset interval duration corresponding to the current running state, and updating a triggering interval period of the client according to the preset interval duration.
In actual operation, the step S1 of acquiring the current network type and the step S2 of acquiring the current running state may be performed separately or simultaneously, where the step of acquiring the current network type and the step of acquiring the current running state are both performed when the client end will establish communication connection with the server, that is, after the monitoring is started, the application will also immediately acquire the current running state of the client end (for example, mobile phone app).
In actual operation, the running state (or working state) of the client in the present application includes: foreground operating state, background operating state, and other states (e.g., suspended state), etc.
The change of the running state of the client in the application refers to that the client is changed from one running state to another running state, for example, the client is transferred from a foreground running state to a background running state.
When in actual work, the preset interval duration and/or the trigger interval period can be recorded into the trigger interval period information table, various preset interval durations are preset in the client according to the real-time running state of the client, different running states correspond to different preset interval durations, when the client and the server just establish communication connection, or after the trigger interval period is reached, the timer arranged in the client can be triggered according to the interval of the trigger interval period, and a keep-alive data packet is built when the timer is triggered.
When in actual work, the triggering interval period of the application mainly refers to interval time (namely preset interval duration) when the timer is triggered at intervals of two adjacent times, and when the running state is monitored to change, the application also responds to the situation that different triggering interval periods are adopted, namely, the application sets different triggering interval periods according to different running states of the client, and the method is as follows:
when the client is in a foreground running state, the specific network type of the client is not distinguished at this time (i.e. the client is not distinguished between the WIFI network and the operator network at this time), the triggering interval periods (i.e. the triggering time of the timer) all adopt the same preset interval duration (e.g. 60 seconds, and can be specifically set by oneself), and the setting mode is as follows:
firstly judging whether a client and a server are in a communication connection state (mainly used for detecting whether a communication link is still available or not, namely, immediately constructing a data packet and sending the data packet to the server to detect whether a response timeout phenomenon exists or not, specifically referring to steps S3-S5 in the application), and then adopting different setting modes according to the judging result of the communication connection state, specifically:
if the client and the server are in a communication connection state, the link is still available (namely, the communication link is in a keep-alive state), and the preset interval duration is set to a certain first fixed value (for example, 60 seconds) at the moment, wherein the first fixed value is used as the preset interval duration and the trigger interval period when the client is in a foreground running state;
If the client and the server are not in the communication connection state, the link is not available (namely, the communication link is in the non-keep-alive state), at the moment, the client actively disconnects the connection state with the server and ends the timer triggering, and after the client and the server reestablish the new communication connection, the triggering interval period is reacquired again according to the current running state of the client.
When the client is in the background running state, the client needs to judge (distinguish) the current network type of the client (i.e. the client needs to distinguish the WIFI network and the operator network at this time), and adopts different trigger interval periods for different network types, and the setting mode is as follows:
firstly, setting a trigger interval period to a certain second fixed value (for example, 200 seconds, and the second fixed value is 2-5 times of the first fixed value), then determining the current network type connected with the client in actual working, and finally adopting different trigger interval period setting modes according to different current network types, wherein the specific steps are as follows:
if the current network type is the WIFI network, the second fixed value is unchanged, and the second fixed value is the triggering interval period when the client is in the background running state and is the WIFI network;
If the current network type is an operator network, acquiring a keep-alive time threshold of the operator network, executing self-increasing detection operation according to the keep-alive time threshold, and prolonging a trigger interval period by executing the self-increasing detection operation, so that an upper limit boundary of the trigger interval period is determined, the detection time and detection times of a client can be reduced, the construction quantity and the transmission quantity of a keep-alive data packet are reduced, the flow waste and the electric quantity consumption are further reduced, and finally the trigger interval period after adjustment (following) is used as the trigger interval period of the application in the operator network and in background operation.
When the client is in other states (e.g., a suspended state): the specific network type of the client is not distinguished at this time, the client only needs to actively disconnect the connection state with the server and end the timer trigger, and the trigger interval period is acquired again according to different working states of the client after the client and the server reestablish new communication connection.
In actual operation, when the self-increasing detection operation is executed according to the keep-alive time threshold, if the response result of the keep-alive data packet sent by the server is accumulated twice within the keep-alive time threshold, the execution of the self-increasing detection operation is stopped, wherein the self-increasing detection operation comprises:
S21, if the response result of the keep-alive data packet sent by the server is successfully received within the keep-alive time threshold, adding one to the response times of the current trigger interval period, wherein the initial value of the response times of the current trigger interval period is zero;
s22, if the response times of the current trigger interval period are not less than a preset time threshold, acquiring a period adjustment value according to the sum of the current trigger interval period and a preset accumulated value;
s23, updating the triggering interval period of the client according to the period adjustment value, zeroing the response times and increasing the preset accumulated value, and returning to the step S21.
When the method and the device actually work, the period adjustment value is divided into effective interval triggering time and ineffective interval triggering time, and then whether the client triggers the timer according to the effective interval triggering time or triggers the timer according to the ineffective interval triggering time is judged.
The valid interval triggering time refers to that the client receives the response result of the server for the keep-alive data packet continuously for 3-5 times when running according to the period adjustment value, the invalid interval triggering time refers to that the client accumulates 2 times when running according to the period adjustment value and does not receive the response result of the server for the keep-alive data packet, and meanwhile, the priority effectiveness of the invalid interval triggering time is larger than the valid interval triggering time, namely, when the client runs according to a certain period adjustment value, if the client accumulates 2 times when not receiving the response result of the server for the keep-alive data packet, the period adjustment value is the invalid interval triggering time, and whether the client continuously receives the response result of the server for the keep-alive data packet is not needed to be considered.
If the client triggers the timer according to the effective interval triggering time, presetting interval span time with sequentially increased multiple groups of tolerance, acquiring a second check result according to the second triggering interval time and each group of interval span time, obtaining a plurality of effective interval triggering times, and taking the effective interval triggering time with the largest value as a period adjustment value of the client when the effective interval time runs;
if the client triggers the timer according to the invalid interval, the client actively disconnects the connection state with the server and ends the timer triggering, after the client and the server reestablish new communication connection, the invalid interval triggering time is initialized to be the last valid time interval, the maximum valid time interval is redetermined according to the valid time interval and the minimum time span, and the redetermined maximum valid time interval is the corrected interval time of the client when the invalid interval time runs;
in actual operation, the first fixed value, the second fixed value, trigger interval period, the sum of preset accumulated values in this application acquire cycle adjustment value and all can set up by oneself as required, simultaneously, this application is when setting up preset accumulated values, can set up the biggest accumulation threshold (like 100 seconds), and minimum accumulation threshold (like 25 seconds), has let this application use more conveniently, simultaneously, in order to explain the technical scheme of this application more clearly, combines the example to explain below:
When the response number of the current trigger interval period is not less than the preset number threshold, that is, when the client is running according to the valid interval trigger time, the period adjustment value is sequentially increased from the second fixed value of 200 seconds, for example, may be 225 seconds, 275 seconds, 350 seconds, 450 seconds and 550 seconds in sequence.
If the client runs according to the above-mentioned certain period adjustment value (for example, 450 seconds), the response result of the server for the keep-alive data packet is accumulated for two times, and then the last valid interval triggering time (for example, 350 seconds) is used as the period adjustment value to enable the client to run.
When a certain period adjustment value (for example, 450 seconds) is an invalid interval triggering time, in order to further reduce the construction quantity and the transmission quantity of the keep-alive data packet, the method can further take the last valid interval triggering time (for example, 350 seconds) as a basis, and redetermine the upper limit boundary of the period adjustment value (triggering interval period) according to a minimum accumulation threshold value each time, wherein the period adjustment value is sequentially increased from a second fixed value of 350 seconds, and can be sequentially 375 seconds, 400 seconds and 425 seconds, and if the period adjustment value is redetermined by the client when the client is in a certain period adjustment value (for example, 425 seconds) or is the valid interval triggering time, the period adjustment value (for example, 425 seconds) is taken as the triggering interval period when the client is in a background running state and is in an operator network; if the period adjustment value is determined to be the invalid interval triggering time again when the client terminal is in a certain period adjustment value (such as 425 seconds), the last valid interval triggering time (such as 400 seconds) of the period adjustment value (such as 425 seconds) is taken as the triggering interval period when the client terminal is in a background running state and is in an operator network.
After determining the upper limit boundary (such as 400 seconds) of the trigger interval period, the client saves the value (such as 400 seconds) in the local database, and when the client monitors that the client is switched to the background state from front to back, the value (such as 400 seconds) saved in the database is directly used as a timer trigger time interval without repeatedly detecting from 200 seconds, so that the detection time and detection times of the client can be reduced, the construction quantity and the transmission quantity of the keep-alive data packet are reduced, and the flow waste and the electric quantity consumption are further reduced.
S3: generating keep-alive data packets at intervals of triggering intervals;
in actual operation, the trigger interval period may also be referred to as a timer trigger time. The client is internally provided with a timer, and a keep-alive data packet is produced while the timer is triggered, wherein the format of the keep-alive data packet is agreed by the client and the server, and the specific components of the format of the data packet are a data packet length bit, a CRC check bit, a data packet header length bit and a data packet header bit, and the specific components are as follows: the data packet length bit occupies 4 bytes and is used for representing the current whole data packet length; the CRC check bit occupies 1 byte, and stores a check code obtained by CRC calculation of a specific numerical value of the length bit of the data packet, so as to check the length correctness of the data packet; the packet header bit occupies 1 byte and is used for representing the packet header occupying length; the packet header bit is at least 1 byte for storing an identification indicating the specific type of the packet.
S41: judging whether the client performs data interaction with the server in the previous trigger interval period to obtain a first check result;
s42: if the first check result is no, a keep-alive data packet is sent to the server and timing is started.
Preferably, the step further comprises: if the first check result is yes, the client and the server are determined to be in a communication connection state.
When the method and the device are in actual work, the data in the data interaction between the client and the server not only comprise the data contained in the keep-alive data packet, but also comprise the data generated by the client and the server during normal data interaction, so that the keep-alive data packet is not sent to the server by the client only in the period of the last trigger interval, and the keep-alive data packet is not sent under the condition of normal data interaction with the server, and therefore, the flow waste and the electric quantity consumption can be reduced, the link unavailability caused by recovery of network resources by operators is avoided, and the detection time and the detection times of the data packet sent by the client are also reduced.
In actual operation, the first checking result comprises that data interaction is not performed and data interaction is performed, and if the data interaction is not performed, a keep-alive data packet is sent to the server; if the data interaction is performed, the client and the server are determined to be in a communication connection state, namely the mobile terminal communication link is in a keep-alive state, and at the moment, the data packet is not sent any more.
S51: after the keep-alive time threshold is reached, judging whether the client receives a response result of the server for the keep-alive data packet, and obtaining a second checking result;
s52: if the second checking result is yes, the client and the server are determined to be in a communication connection state.
Preferably, the step further comprises: if the second checking result is negative, determining that the client and the server are in a communication disconnection state; and when the communication connection between the client and the server is detected, the current running state and the current network type of the client are acquired again.
In actual operation, the second checking result comprises that no response result is received, and the response result is received, if the response result is not received, the client actively disconnects the communication connection established with the server, and ends the timer triggering, and after the client reestablishes the communication connection with the server, the S1-S52 is repeatedly executed; if so, the client continues to operate until no response result is received.
In order to make the client more intelligent when the link is kept alive, thereby improving the use experience of the user, the method for optimizing the keep-alive of the communication link of the client further comprises the following steps:
and S6, when the client monitors that the network type is changed and the client and the server are in a communication connection state, the client actively disconnects the link and ends the timer to trigger, and after a new communication connection is reestablished, the process of the steps S1 to S5 is repeatedly executed.
In this step, when the client monitors that the network type changes, that is, when the client monitors that the mobile phone network link state changes, except that the mobile phone network link state is switched from the meshed state to the non-meshed state (only the timer is required to be ended in this case), the client is required to actively disconnect the link and end the timer to trigger no matter what network type the mobile phone is in (including the network change between different operators and WIFI from the non-meshed state to the meshed state, and the like), and the processes of steps S1 to S5 are repeatedly executed after a new communication link is re-established.
In actual operation, in the application, the client does not distinguish which operator the operator link is specific to during actual operation, that is, the client operates in the same manner for different operators (for example, GPRS, EDGE, WCDMA, CDMA, LET), but the setting manners of the different operators are the same when the threshold time and the timer trigger time are set.
Specifically, under different network types, the operation mode of the client is as follows:
the mobile phone is in a state without network link or in a suspended state: at this time, the client is in an abnormal working state, the client does not send a data packet to the server, and the timer does not work.
The mobile phone is in a WIFI network link state: the operation mode of the client is performed according to the procedures of steps S1 to S5, and the threshold time and the timer triggering time of the client can refer to step S2 specifically, which is not described herein.
The mobile phone is in an operator network link state: the specific operation mode of the client is performed according to the mode of step S2, at this time, the threshold time of the client is not reset in the operation process, but the timer trigger time of the client adopts different setting modes according to different operation states of the client, and how to acquire and keep pace with the new interval trigger period can refer to step S2, which is not described herein.
