Line mode for data transfer. Please refer to the relevant operation logic for further reference. 2 picture. FIG. 2 is a schematic diagram of a connection process 20 according to an embodiment of the present invention. The connection process 20 can be used in any of the communication devices CD_1~CD_n, and can be compiled into a code 106 and stored in the storage unit 104. The connection process 20 includes the following steps:

Step 200: Start.

Step 202: When receiving an instruction to transmit a data to be transmitted to another communication device, determining at least one data characteristic of the data to be transmitted and at least one of a plurality of wireless connection modes with respect to the other communication device Connection characteristics.

Step 204: Select a communication module by the communication module CM_1~CM_m according to the at least one data characteristic of the data to be transmitted and the at least one connection characteristic of the plurality of wireless connection modes of the second communication device. To transmit the to-be-transmitted data to the other communication device.

Step 206: End.

According to the connection process 20, when any of the communication devices CD_1~CD_n (for example, CD_x) receives an instruction to transmit a data to be transmitted to another communication device (for example, CD_y), the communication device CD_x first Determining the data characteristics of the data to be transmitted and the connection characteristics of all the wireless connection modes of the communication device CD_y, and then selecting a communication module from the communication modules CM_1~CM_m to transmit the data to be transmitted to the communication device CD_y. In other words, the communication device CD_x can dynamically and automatically select the appropriate according to the data characteristics (such as data volume, security, timeliness, etc.) and the connection characteristics of the wireless connection mode (such as transmission capacity, retransmission mechanism, encryption and decryption mechanism, etc.). The communication module transmits the data to the communication device CD_y. In this way, it is ensured that the data is correctly and efficiently transmitted to the communication device CD_y.

For example, when the amount of data to be transmitted is large, or the transmission of the data to be transmitted needs to be completed in a short time, the communication device CD_x can select a wireless connection mode with a large transmission capacity and activate the corresponding communication. The module performs data transmission. When the data of the data to be transmitted is relatively high, or when the transmission process is to be kept secret, the communication device CD_x may select a wireless connection mode with a high degree of confidentiality and activate the corresponding communication module for data transmission. According to this, the communication device CD_x can be confirmed The data is transmitted to the communication device CD_y correctly and efficiently.

It should be noted that the connection process 20 is an embodiment of the present invention, and those skilled in the art can make different modifications according to the present invention, and are not limited thereto. For example, according to step 202, the communication device CD_x needs to first determine the data characteristics of the data to be transmitted, and the method of determining may be appropriately adjusted according to the system architecture or requirements. In an embodiment, if the data to be transmitted includes a security flag, the security of the data to be transmitted may be determined according to the security flag; if the data to be transmitted does not include the security flag, The packet type judges its security. Generally speaking, the Acknowledgement packet has lower security requirements, the data packet security requirement is higher, and the key or key class packet has the highest security requirement. On the other hand, if the data to be transmitted contains a data volume field, the amount of data to be transmitted can be judged accordingly; if the data to be transmitted does not include the data volume field, the amount of data to be transmitted can be directly calculated. . In addition, if the content of the data to be transmitted is packet data generated by an instant messaging application such as VoIP, the data to be transmitted is time-sensitive and needs to be transmitted immediately.

In addition, according to step 202, the communication device CD_x still needs to determine the connection characteristics of the wireless connection mode with respect to the communication device CD_y, such as the connection quality or the connection security, and is not limited thereto.

For example, in an embodiment, the test packet can be sent to the communication device CD_y through the communication modules CM_1~CM_m to determine the transmission amount or signal quality that each communication module CM_1~CM_m can reach; in another embodiment, The judgment result of the connection quality can be stored as a reference for the subsequent transmission of the data; in another embodiment, the user can specify the priority of the communication modules CM_1~CM_m. On the other hand, the connection security may be determined according to whether the data to be transmitted is encrypted or not, or may be determined by the transmission range of the wireless connection mode; for example, if the transmission range is only a few meters of the wireless connection mode. Naturally, the data will not be stolen by other communication devices beyond tens of meters. In the same way, the judgment result of the connection security can also be stored in the communication device CD_1~CD_n as the reference basis for the subsequent transmission of the data.

After determining the data characteristics of the data to be transmitted and the connection characteristics of the wireless connection mode, in step 204, the communication device CD_x can select a communication module from the communication modules CM_1~CM_m to transmit the data to be transmitted to another A communication device. For example, if the security of the data to be transmitted is high security requirement or greater than a predetermined level, the communication device CD_x may select a wireless wireless connection mode (or a wireless connection greater than a certain security level) from the communication modules CM_1~CM_m. The communication module of the mode transmits the data to be transmitted; if the data volume of the data to be transmitted is greater than a preset value, the communication device CD_x may select a wireless connection mode capable of high transmission by the communication modules CM_1~CM_m (or The communication module that transmits the wireless connection mode whose capacity is greater than a preset value transmits the data to be transmitted.

Furthermore, if it is not necessary to consider the security and data volume of the data to be transmitted, or the security and data volume of the data to be transmitted is not up to standard, or the security and data volume of the data to be transmitted cannot be judged, then In the example, the communication device CD_x can select the communication module with the strongest signal strength to transmit the data to be transmitted. On the other hand, the security and data volume of the aforementioned data to be transmitted are used to exemplify the characteristics of the data, but are not limited thereto, and those having ordinary knowledge in the field may be appropriately adjusted, for example, according to timeliness, data type, Data sources, etc., set appropriate rules; of course, you can also use the weights between different data characteristics or different data characteristics as the basis for selecting the wireless connection mode, for example, taking security as a priority, and considering the amount of data and timeliness. Sex, etc., are all within the scope of the present invention. Similarly, the connection characteristics of the wireless connection mode are not limited to the transmission capacity and the signal quality. Others such as the operation frequency band and the number of channels can be used as the basis for judgment, and the weights of different connection characteristics can also be set.

On the other hand, in the foregoing description, the data to be transmitted indicates that the communication device CD_x is instructed to transmit the data to the communication device CD_y, which may be that the user instructs the processor 102 of the communication device CD_x to generate and transmit to the communication device CD_y, or It is generated by the processor 102 of the Internet device instructing the communication device CD_x and transmitted to the communication device CD_y, or generated by the communication device other than the communication devices CD_x, CD_y and transmitted to the communication device CD_x, and indicates The processor 102 of the device CD_x transmits to the communication device CD_y.
