[0036] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0037] Example 1

[0038] like Figure 1 to Figure 2 As shown, the present invention analyzes the network link establishment protocol and proposes a method for wireless data access and link establishment between the command post communication equipment and the communication terminal. The method is combined with the actual application scenario to divide the link establishment signal into two paths: wireless network control data and wireless service data, and has high reliability. The interactive protocol is compiled according to the actual situation, and it is more in line with practical applications on the basis of simplification. This method increases the connectivity of the system and ensures the stability of the communication system.

[0039] A method for establishing a link between a command post communication device and a communication terminal has two stages: a pre-mission preparation stage and a mid-mission processing stage. The processing of each stage is briefly described as follows:

[0040] 1) In the pre-task processing stage, the communication terminal loads the wireless frequency band information stored in its own memory.

[0041] 2) The task processing stage mainly completes the wireless network access protocol interaction and wireless service information interaction. It can be roughly divided into network control command sending, network control link search, network access application, network access response, wireless resource update download, service link establishment response, and service communication.

[0042] The interactive process of the method of the present invention is as follows Figure 1 .

[0043] (I) Pre-task processing stage: The communication terminal loads the wireless frequency band information. The content of the wireless frequency band information is shown in Table 1.

[0044] Table 1 Wireless frequency band information content table

[0045]

[0046] (II) Processing stage of the task:

[0047] 1) The command post communication equipment selects a frequency band from the wireless frequency band information loaded by the communication terminal and sends network control commands at a continuous interval of 10ns.

[0048] 2) The communication terminal configures the frequencies (including the main and backup frequencies) one by one according to the loaded wireless frequency band information and searches for the network control command.

[0049] After the communication terminal locks the network control command according to a certain locking method (for example, according to the information signal quality threshold, etc.), it receives and parses the "network control command" command (the command format of network control command 1 is shown in Table 2) to obtain the relevant information of the network control command transmission frequency point of the current communication terminal.

[0050] Table 2 Network control command content table

[0051]

[0052] 3) The communication terminal sends a "network access application" command at a certain frequency according to the obtained network control command (the format of the network access application command is shown in Table 3).

[0053] Table 3 Network access application command content table

[0054]

[0055] 4) The command post communication equipment confirms the relevant information according to the "Network Access Application" command, and sends the confirmation result to the communication terminal through the "Network Access Response" command (the format of the Network Access Response command is shown in Table 4).

[0056] Table 4 Network access response command content table

[0057]

[0058] The communication terminal continues to send the "network access application" command at a fixed time until the communication terminal receives the "network access response", and then stops sending the "network access application" command.

[0059] 5) The communication terminal determines whether wireless resource over-the-air replenishment (wireless resource update) is required based on the "network access response" command. If necessary, it receives the wireless resource update download command over-the-air (the wireless resource update download command format is shown in Table 5).

[0060] Table 5 Wireless resource update download command content table

[0061]

[0062] 6) For the communication terminal that needs to carry out business communication, upon receiving the wireless resource update download command, a business link establishment response is sent through the obtained business working frequency point.

[0063] 7) The command post communication equipment receives the service link establishment response and performs service interaction with the communication terminal according to the needs.

[0064] The specific process of network access and link establishment of the present invention is as follows Figure 2 .

[0065] The present invention proposes a method for establishing a wireless data network link between a command post communication device and a communication terminal. The method designs the communication scenario, process and specific communication protocol for each interaction in combination with the application scope. For the link, the wireless network control data and the wireless service data are divided into two paths to ensure the independence of the link and the function, so that the reliability of the process is high.

[0066] The present invention designs necessary and indirect protocol contents for each process interaction protocol of the method according to the application scenario, thereby ensuring the basis of stable interaction and reducing the complexity of the interactive system. If the application scenario becomes complex and more interactive information needs to be added, only information needs to be added to each interactive protocol, while the process remains unchanged. The portability and extensibility of the entire method can be guaranteed.

[0067] The present invention adopts a dual-link data separation transmission design and proposes a method for dividing the link establishment signal into two paths, wireless network control data and wireless service data, for separate transmission. By separating network control data from service data, the independence of links and functions is made stronger, and the reliability and stability of data transmission between modules during the communication process can be improved. This design can effectively reduce service data interference and loss while ensuring the reliability of the data link.

[0068] The present invention is adaptable to configurable interactive protocols in different scenarios, designs a variety of network access interactive protocol contents based on application scenarios, and can be increased, decreased or modified according to application requirements, thereby improving the applicability and flexibility of the protocol. Each interactive protocol contains necessary and indirect protocol fields, so that the system achieves a balance between stability and complexity. The solution can adapt to different types of communication scenarios, such as emergency communications, and provides a general link establishment method for communications in multiple scenarios.

[0069] The dynamic over-the-air filling and downloading of wireless resources of the present invention adds an over-the-air filling and updating and downloading mechanism of wireless resources to the traditional network access interaction process. The communication terminal determines whether it is necessary to perform over-the-air filling of wireless resources based on the network access response information of the command post communication equipment. By filling wireless resources over the air, the terminal can dynamically receive and update the wireless resource configuration as needed during the mission, thereby improving the real-time and flexibility of the communication network and ensuring that resource configuration can be completed quickly and efficiently in different communication tasks.

[0070] As described above, the present invention can be preferably implemented.

[0071] All features disclosed in all embodiments in this specification, or steps in all methods or processes implicitly disclosed, except for mutually exclusive features and / or steps, can be combined and / or expanded or replaced in any manner.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
