[0002] At present, some units have a variety of network resources available for use, such as the public security system's 340M video and image transmission network, 350M PDT network, 800M network, satellite network, operator 4G / 5G, etc. Using different networks in different scenarios has great differences in stability such as network delay and jitter. Therefore, in order to have a better network usage experience, it is necessary to switch network connections in these different scenarios. The traditional way is to manually switch network connections based on user experience and current needs.

In addition, the accuracy of manual network selection is limited, and it is impossible to determine that the manually selected network is the network with the best current communication quality. At the same time, it is often necessary to configure relevant parameters when switching between different networks, and the operation is too complicated. Summary of the invention

[0045] Specifically, the adaptive method for cross-domain network cooperative communication provided by the present invention is a method for allowing a network access terminal with multiple network modules to autonomously select the optimal network access in an environment with a complex access network.

[0046] Furthermore, this method must first clarify which network modules the terminal supports. Therefore, it is necessary to scan the network module characteristics of the terminal through the communication module, obtain the network access characteristics of the terminal, establish a terminal model of the terminal, and rely on the terminal model to try to connect to the network to evaluate the communication quality of the network.

[0047] In a preferred embodiment, the network health status level table includes N health levels, namely, the first priority level, the second priority level, the third priority level to the Nth priority level, wherein N is a positive integer.

[0048] Specifically, the health level refers to the health status of the network under different network congestion conditions among all connected networks. In this embodiment, N is preferably 5, that is, the network health status level table includes the first priority level, the second priority level, the third priority level, the fourth priority level and the fifth priority level, and the network health status of the network from the first priority level to the fifth priority level decreases in sequence.

[0049] In a preferred embodiment, the health levels are respectively corresponding to quantifiable network indicators. Specifically, the network indicators include network delay and packet loss rate. Furthermore, they may be other indicators related to network performance, such as bandwidth, jitter, etc.

[0050] In a preferred embodiment, Figure 2 As shown, step S2 includes,

[0051] Step S21, comparing the communication quality of each network at different health levels when connected to the terminal;

[0052] Step S22, determining the order of communication quality of each network at different health levels according to the comparison result.

[0053] In a preferred embodiment, Figure 3 As shown, step S3 includes,

[0054] Step S31, real-time detection of the health level of the network currently connected to the terminal;

[0055] Step S32, determining the communication quality of the currently connected network based on the network indicator corresponding to the health level of the currently connected network.

[0056] In a preferred embodiment, Figure 4 As shown, step S4 includes,

[0057] Step S41, based on the communication quality ranking result in step S22, determine whether the communication quality of the currently connected network is the best communication quality. If so, maintain the connection of the current network and continue to execute step S41; otherwise, execute step S42;

[0059] Step S43, comparing the evaluation result with the communication quality of the currently connected network, if the evaluation result is better than the communication quality of the currently connected network, disconnecting the current network and switching the network connection of the terminal to the network to be tried; otherwise, maintaining the current network connection;

[0060] Step S44, return to execute step S41.

[0061] In a preferred embodiment, the network includes a frequency band private network, a satellite network and an operator network. The specific networks in this technical solution include 340M video image transmission private network, 350M PDT private network, 800M private network, satellite network, operator 4G / 5G and other network resources suitable for the public security system.

[0062] An adaptive system for cross-domain network collaborative communication, applied to an adaptive method for cross-domain network collaborative communication in any one of the embodiments, comprises:

[0063] A communication module is provided in the terminal and is used to scan the network access characteristics of the terminal and establish a terminal model;

[0064] The server is connected to the communication module and is used to transmit the connection parameter information of the network to the communication module.

[0065] In a preferred embodiment, the terminal is provided with a network access module connected to the communication module for supporting the terminal to access multiple networks and for switching the network connection of the terminal.

[0066] In a preferred embodiment, the preferred access networks include: network A, network B, network C and network D. A network health status level table is established in all access networks supported by the terminal under different network congestion conditions, including the first priority level, the second priority level, the third priority level, the fourth priority level and the fifth priority level. The network health status of the network from the best level to the fifth priority level decreases in sequence, and quantifiable network indicators are given to each level of health level, including network delay, packet loss rate, etc.; further, in this embodiment, network B has a communication quality better than all other networks at all health levels at the best level, the communication quality of network A at the third priority level is better than that of network B at the second priority level, and the communication quality of network B at the third priority level is better than the communication quality of network C and network D at all health levels;

[0067] Furthermore, if Figure 5 As shown, a communication module is integrated in a terminal accessing the network, and the communication module scans the hardware device information of the terminal and establishes a terminal model;

[0068] Furthermore, if Figure 6 As shown, the preferred terminal of this embodiment supports the connection of network A and network B. Assume that the current terminal is connected to network B and is at the first priority level;

[0069] Furthermore, due to external interference, the health level of network B gradually decreases to the second best level. At this time, the communication module starts the network evaluation, selects a network whose communication quality may be better than that of network B for trial connection, that is, network A, and determines the health level of network A;

[0070] If the health level of network A is the third best level, and it is known that the communication quality of network A with the third best level is better than the currently connected network B with the second best level, then the terminal will automatically switch to connecting to network A and close the connection channel of network B to save terminal power. If the health level of network A is lower than the third best level, that is, the communication quality of network A is lower than the currently connected network B with the second best level, then the terminal will maintain the connection with network B. Finally, the function of the terminal always maintaining the connection with the network with the best communication quality is realized.

For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
