[0074] If the first signal strength exceeds the preferred signal strength threshold, the second main control module 22 will use the currently logged-in mobile communication network as the corresponding first optimal network.

[0075] If the first signal strength does not exceed the preferred signal strength threshold, the second main control module 22 sends a first new number application instruction to the first cloud platform 4 through the first mobile communication module 24, and receives the first new number data sent back by the first cloud platform 4. Based on the first new number data, it updates the non-seed number in the non-seed number storage area of ​​the first eSIM module 23 where the number activation status is inactive. When the number update is successful, the new number corresponding to the first new number data is used as the new first number, the activation status of the number corresponding to the currently updated non-seed number storage area is updated to activated, and the activation status of the numbers corresponding to all other non-seed number storage areas in the first eSIM module 23 is updated to inactive. Then, the first mobile communication module 24 is invoked to perform mobile communication again based on the new first number. The system performs network registration processing. Upon successful network registration again, the first mobile communication module 24 is invoked to detect the network signal strength of the currently registered mobile communication network to obtain a new first signal strength. The system then identifies whether the new first signal strength exceeds the preferred signal strength threshold. If the new first signal strength exceeds the preferred signal strength threshold, the currently registered mobile communication network is taken as the corresponding first optimal network. If the new first signal strength does not exceed the threshold, the first mobile communication module 24 continues to send a first new number application instruction to the first cloud platform 4 to initiate a new round of new number application processing until the new first signal strength exceeds the preferred signal strength threshold. Finally, the mobile communication network where the new first number registered with the new first signal strength is obtained is taken as the corresponding first optimal network.

[0076] Upon obtaining the first optimal network, the second main control module 22 sets the flashing frequency of the second signal light 26 to a preset second flashing frequency and sets the signal light color of the second signal light 26 to green; the second flashing frequency is less than the first flashing frequency.

[0077] In another specific implementation of this invention, the first relay device 2 is specifically used to, when performing Bluetooth channel creation processing with the first acquisition device 3, have the second main control module 22 set the flashing frequency of the third signal light 27 to a preset first flashing frequency and set the signal light color of the third signal light 27 to red; and have the second main control module 22 call the second Bluetooth communication module 21 to perform device retrieval on Bluetooth devices near the relay device to obtain the corresponding second device list; and have the second main control module 22 select one or more second device identifiers that meet the naming rules from the second device list according to the preset acquisition device identifier naming rules as the corresponding first acquisition device identifiers; and have the second main control module 22 call the second Bluetooth communication module 21 to perform Bluetooth data transmission channel creation processing between the first relay device 2 and the first acquisition device 3 corresponding to each first acquisition device identifier to obtain the corresponding second data channel; and when the second data channel is successfully created, have the second main control module 22 set the flashing frequency of the third signal light 27 to a preset second flashing frequency and set the signal light color of the third signal light 27 to green; wherein, the second device list includes multiple second device identifiers; and the second flashing frequency is less than the first flashing frequency.

[0078] Here, when the second main control module 22 calls the second Bluetooth communication module 21 to search for Bluetooth devices near the relay device, it does so based on the conventional Bluetooth device search process. Similarly, when the second main control module 22 calls the second Bluetooth communication module 21 to create Bluetooth data transmission channels between the first relay device 2 and the first acquisition devices 3 corresponding to each first acquisition device identifier, it also does so based on the conventional Bluetooth device connection process. Furthermore, to facilitate the second main control module 22 in automatically selecting one or more first acquisition device identifiers from the second device list, this embodiment of the invention also presets a corresponding acquisition device identifier naming rule for this automatic selection process. This acquisition device identifier naming rule defines the device identifier naming rules for all first acquisition devices 3 in the system of this embodiment of the invention. Based on this rule, the second main control module 22 can automatically select one or more first acquisition device identifiers that satisfy the rule from the second device list.

[0084] In addition, when the first relay device 2 establishes a first data channel with the first handheld device 1, the second main control module 22 sets the flashing frequency of the first signal light 25 to a preset first flashing frequency and sets the signal light color of the first signal light 25 to red; and the second main control module 22 performs Bluetooth data transmission channel creation processing with the first Bluetooth communication module 11 of the first handheld device 1 through the second Bluetooth communication module 21; and when the first data channel is successfully established, the second main control module 22 pushes the locally preset first application installation package to the first handheld device 1 through the first data channel, sets the flashing frequency of the first signal light 25 to a preset second flashing frequency and sets the signal light color of the first signal light 25 to green; wherein, the second flashing frequency is less than the first flashing frequency.
