In the embodiment of the application, the content of each message is simplified according to the preset rule so as to reduce the size of the data packet of the message, thereby reducing the occurrence of the packet loss phenomenon. For example: the message format sent by a rescue worker is 'time' + 'coordinate' + 'event level' + 'whether supporting is needed' + 'supporting level' + 'supporting type', the message to be sent is 'month and month of a certain year, east longitude and latitude, the event type is A level, supporting level is A, supporting type is medical treatment and engineering truck', and the actually sent message is 'binary data a, binary data b, A, A, C+D'.
When the communication type is long connection communication, the following measures are taken:

Specifically, historical data of communication with a request end is obtained, and historical time delay, network speed and packet loss rate of a communication link are obtained, and average duration of communication with the request end and stable duration of communication of each communication link are obtained; the call stability duration is the effective duration without interruption in the communication process.
The average duration of the call at the requesting end is lower than the duration of the call stability, which means that the probability of occurrence of the phenomenon of connection interruption in the call process is lower and the call stability is better.
And establishing a communication model according to the historical relations of delay, network speed, packet loss rate and call stability duration. The relation between the delay, the network speed and the packet loss rate and the network state is recorded in the communication model, and when one of the numerical values changes, the influence on the communication result is generated.
And acquiring the current delay, network speed and packet loss rate of the communication link.
Based on the communication model, the predicted call stability duration of the communication link and the score of the communication link are obtained according to the current delay, the network speed and the packet loss rate of the communication link.
The communication link that scores the highest and predicts that the length of the call will be longer than the average length of the request-side call when the call is stable is selected. If the highest scoring communication link does not meet the lowest score of the long-connection communication, selecting to use the short-connection communication.
For example: according to the communication model, the scores of the communication links with stable signals are full, the delay, the packet loss rate and the network speed respectively correspond to a score table according to the pre-test result, and the corresponding scores are reduced by N scores when the delay is increased by 1ms, and the like.
In order to further improve the accuracy of message transmission, the application further comprises the steps of sending a message of short connection communication according to the call content of long connection communication:
respectively acquiring audio information of communication contents of both communication parties; obtaining corresponding text information according to the audio information; acquiring an encryption rule corresponding to identity authentication information of a communicator; and obtaining messages of short-connection communication according to the text information and the encryption rule, and respectively sending the messages to the other end of the communication.
