Background

As shown in fig. 1, in the application scenario of online inquiry, the inquiry function of the host client and doctor client as IOS terminals is instant messaging (Instant Messaging, IM) implemented based on socket. IM allows two or more people to communicate text messages, files, voice, and video in real time using a network.

In the case of good network conditions, messaging between the host client and the doctor client is completed within 1 second. However, with the rapid increase of the number of users, various unexpected situations can occur in the existing online inquiry system, such as that if users cannot send messages or receive messages in real time when using the online inquiry system, the failure rate of message sending is as high as 0.3% to 0.4%, so that the user experience is seriously affected.

The reasons for the failure of the IOS terminal message transmission mainly comprise the following steps:

(1) Due to the unique mechanism of IOS, APP will be suspended when the user switches to the background, and all ongoing network requests will be discontinued. Thus, if the message is not yet sent to the server, the message will fail to be sent.

(2) Since a picture or voice type file is large, a long transmission time is required. If APP hangs up during transmission, this results in message transmission failure.

Therefore, there is an urgent need to improve the failure rate of the IM messaging of the IOS terminal, so as to meet the actual requirement of the IOS terminal for messaging.

Detailed Description

Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention.

It should be noted that, the illustrations provided in the present embodiment merely illustrate the basic concept of the present invention by way of illustration, and only the components related to the present invention are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complex.

According to the IM message sending method, the system, the storage medium and the computer equipment of the IOS terminal, through setting the APP keep-alive task and the retry mechanism, the receiving and transmitting failure rate of the IM message can be greatly reduced, and even the receiving and transmitting failure rate can be reduced by one order of magnitude; meanwhile, the user does not feel the sending of the IM message, and the user experience is greatly improved.

As shown in fig. 2, in one embodiment, the IM message transmission method of the IOS terminal of the present invention includes the following steps:

step S1, when an APP of an IOS terminal is switched to a background, the IOS terminal establishes an APP keep-alive task to provide keep-alive time with preset duration, wherein the keep-alive time is used for the APP to send and finish IM messages being sent.

Specifically, at the IOS terminal, the APP exiting to the background is typically suspended for a few seconds or so. Different devices and operating states may affect the hang time of the APP. The suspension time of APP under different operating conditions may vary between 5S and 10S for the same device. In the invention, when the APP is switched to the background, in order to avoid interruption of the current message transmission, an APP keep-alive task is established, so that the APP can still transmit the IM message within the preset time length specified by the keep-alive task, and the socket connection is actively disconnected when the keep-alive task is ended. It should be noted that, adding the APP keep-alive task is allowed by the IOS system, and the APP audit is not affected, so the method has extremely strong safety and feasibility.

In an embodiment of the present invention, the preset duration is set to 30 seconds.

In one embodiment of the present invention, establishing an APP keep-alive task includes the steps of:

11 When the APP of the IOS terminal is switched to the background, wake-up information is sent to the APP.

12 Building the APP keep-alive task based on the wake-up information to place the APP in a surviving state.

Preferably, wake-up information is sent to the APP according to a preset period, so that the APP is always in a survival state.

And S2, acquiring retry parameters, and retransmitting the IM message based on the retry parameters when the IM message fails to be transmitted.

In an embodiment of the present invention, obtaining a retry parameter, and retransmitting the IM message based on the retry parameter when the transmission of the IM message fails, includes the steps of:

21 A total timeout period threshold, a single timeout period threshold, and a number of retries are obtained.

Specifically, the IOS terminal is preset with a total timeout duration threshold, a single timeout duration threshold and retry times.

The single timeout period threshold represents a timeout period threshold when the IM message is sent once. If the single transmission time length is smaller than the single timeout time length threshold, judging that the single transmission has no timeout; and if the single transmission time length is greater than or equal to the single timeout time length threshold, judging that the single transmission is timeout.

The total timeout period threshold represents a timeout threshold for a total duration of multiple transmissions of the IM message. If the time length of the multiple transmissions is smaller than the total timeout time length threshold, judging that the multiple transmissions have no timeout; and if the time length of the multiple transmissions is greater than or equal to the total timeout duration threshold, judging that the multiple transmissions are overtime.

The retry number indicates the number of times an IM message can be retransmitted after a transmission failure.

In an embodiment of the present invention, the total timeout period threshold is set to 120 seconds; the single timeout period threshold is set to 15 seconds; the number of retries was set to 8. It should be noted that the above parameter setting may be flexibly set according to different application scenarios and devices, and is not limited to the above limitation.

22 If the single transmission time of the IM message is longer than the single timeout period threshold, retransmitting the IM message.

Specifically, in order to ensure the effective transmission of the IM message, when the single transmission time of the IM message is longer than 15 seconds, it is determined that the transmission of the IM message is overtime, and retransmission is required. It should be noted that, the retransmission of the IM message is automatically performed by the system, and the user does not need to feel, or manually operate, and the use experience of the user is not affected.

Preferably, when the number of retransmission times of the IM message reaches a preset number of times, the APP actively disconnects the socket connection and then reestablishes the socket connection to retransmit the IM message, thereby improving the success rate of transmission of the IM message. Preferably, the preset number of times is 3.

23 Record the number of retransmissions in real time and the cumulative length.

Specifically, a real-time number counter and an accumulated time length counter can be set, the real-time number counter is updated according to the actual retransmission number, and the accumulated time length counter is updated according to the actual transmission time length.

24 When the real-time number is larger than the retry number or the accumulated time length is larger than the total timeout time length threshold, judging that the IM message transmission fails; and retransmitting the IM message when the real-time number is smaller than or equal to the retry number and the accumulated time length is smaller than or equal to the total timeout time length threshold.

Specifically, the real-time times and the accumulated time length are monitored, and when the two conditions that the real-time times are greater than the retry times and the accumulated time length is greater than the total timeout time length threshold value are met, the IM message transmission failure is judged, and retransmission is not performed.

In an embodiment of the present invention, the method for sending IM messages of the IOS terminal further includes monitoring a current network state, and controlling socket connection of the APP according to different network states, so as to ensure normal sending of the IM messages. Specifically, if the current network state is a disconnected state, the APP disconnects the socket connection. If the current network state is the connection state, the APP is caused to reestablish socket connection. When the network state is disconnected and reconnected, the APP is required to reestablish the socket connection.

In an embodiment of the present invention, the method for sending IM messages of the IOS terminal further includes setting an automatic retransmission mechanism when the type of the IM message is a picture or a voice file. Specifically, when the type of the IM message is a picture or a voice file, a transmission failure is liable to occur. Therefore, the invention automatically sets a retransmission mechanism with preset times for the IM information of the picture or the voice file. When the IM message of the picture or the voice file fails to be sent, the preset times of retransmission are automatically carried out, so that the sending success rate of the IM message is improved as much as possible.

The IM messaging method of the IOS terminal of the present invention is further illustrated by the following specific embodiments.

Example 1

In this embodiment, user a needs to send video information to user B based on the WeChat APP in the smartphone. After the user a sends the video information in the WeChat APP, the user may exit the WeChat APP. At this time, the WeChat APP runs in the background. Because the video information occupies a larger storage space, the WeChat APP needs to continue sending the video information in the background. First, an APP keep-alive task is established to provide a keep-alive time of 30 s. That is, the WeChat APP can still transmit the video information in the background within 30 s. And if the video information is failed to be sent, retransmitting. If the transmission is not successful within 60s or the retransmission is not successful 3 times, the retransmission of the video information is stopped.

Example two

In this embodiment, user a needs to send image information to user B based on the flybook APP in the smartphone. After user a sends image information in flyer APP, the user may exit flyer APP. At this time, the flyer APP runs in the background. Because the image information occupies a large storage space, the flyer book APP needs to continue sending the image information in the background. First, an APP keep-alive task is established to provide a keep-alive time of 20 s. That is, the flyer APP can still transmit the image information in the background within 20 s. And if the image information is failed to be sent, retransmitting. If the transmission is not successful within 40s or the retransmission is not successful 3 times, the retransmission of the image information is stopped.

Example III

In this embodiment, user a needs to send audio information to user B based on QQAPP in the smartphone. After user a sends the audio information in the QQAPP, the user may exit the QQAPP. At this time, the QQAPP runs in the background. Because the audio information occupies a larger storage space, the QQAPP needs to continue to transmit the audio information in the background. First, an APP keep-alive task is established to provide a keep-alive time of 20 s. That is, the QQAPP can still transmit the audio information in the background within 20 s. And if the audio information is failed to be sent, retransmitting. If the transmission is not successful within 60 seconds or the retransmission is not successful for 5 times, the retransmission of the audio information is stopped.

As shown in fig. 3, for IM message transmission between two IOS terminals, such as a doctor terminal and a host client, the IM message transmission method of the IOS terminal of the present invention can effectively reduce failure rate of IM message transmission, can meet requirements of actual application scenarios, and has no perception between the doctor terminal and the host client.

23 Record the number of retransmissions in real time and the cumulative length.

In an embodiment of the present invention, the IM message sending system of the IOS terminal further includes a monitoring module, configured to monitor a current network state, and control socket connection of the APP according to different network states, so as to ensure normal sending of the IM message. Specifically, if the current network state is a disconnected state, the APP disconnects the socket connection. If the current network state is the connection state, the APP is caused to reestablish socket connection. When the network state is disconnected and reconnected, the APP is required to reestablish the socket connection.

In an embodiment of the present invention, the IM messaging system of the IOS terminal further includes a setting module configured to set an automatic retransmission mechanism when the type of the IM message is a picture or a voice file. Specifically, when the type of the IM message is a picture or a voice file, a transmission failure is liable to occur. Therefore, the invention automatically sets a retransmission mechanism with preset times for the IM information of the picture or the voice file. When the IM message of the picture or the voice file fails to be sent, the preset times of retransmission are automatically carried out, so that the sending success rate of the IM message is improved as much as possible.
