In order to be compatible with the software version of the heterogeneous network and realize free switching between the software version of WiFi and the software version of LTE, the embodiment of the present invention provides a software version compatibility method of the heterogeneous network, which can be executed by the terminal. The following content of the embodiment of the present invention The terminal in may be the terminal 106 shown in FIG. 1 , and the network device in the following content may be the network device 102 shown in FIG. 1 . It should be understood that in the present invention, the steps performed by the terminal may also be specifically performed by a module or component of the terminal, for example, may be performed by a chip in the terminal. The following embodiments are described with the terminal as the execution subject. Fig. 2 shows a flow chart of a software version compatibility method for a heterogeneous network provided by an embodiment of the present invention, and the method includes:

S201, read the hardware attribute of the terminal;

S202. When it is determined according to the hardware attribute that the current mode of the terminal supports only the WiFi mode, stop loading and start the modem service; when it is determined according to the hardware attribute that the current mode of the terminal supports the LTE mode, load and start the modem service.

The hardware attribute in the present embodiment can refer to the general-purpose input/output (General-purpose input/output, GPIO) of hardware and chip identification mark (chipid), because the gpio of different software versions, chipid etc. are different, therefore adopt system command line ( cmdline) to read hardware attributes to realize the self-adaptation of software version switching, that is, the Modem control (control) service needs to judge whether to load and start the Modem by parsing the cmdline. It can be seen that the terminal system can dynamically load the modem service according to the hardware attributes, and realize free switching between the WiFi software version and the LTE software version.

The process of loading and starting the modem service in this embodiment mainly refers to: initialize the structure related to the modem service, move the code related to the modem service or other subsystems to the designated area, and move the After completion, the related registers for controlling the operation of the modem are released, and finally, the modem service service starts successfully. It can be seen that when the current mode of the terminal supports only WiFi mode, the modem-related structures are not initialized, such as Removeinitcploadinfo, and the modem-related codes (such as Removecploadinfoimg) are not moved, and the relevant registers that control the modem operation are not released. Create a task for modem monitoring, such as Removelistenmodemtask, and no longer transmit the message of modem activation (alive) to each client (client), such as Removewait modemalive.

In a possible implementation manner, when the Modem-related device node determines that the current mode of the terminal is only supporting WiFi mode according to the hardware attribute, the device node is adaptively deleted. For example, as shown in FIG. 3, when the terminal system is started, first Determine whether the current mode of the terminal supports only WiFi mode, if so, remove the device nodes of the LTE network, such as stty_lte/sdiag_lte/spipe_lte/sipc_lte/spool and other device nodes; otherwise, complete the dynamic loading of the modem service and end.

In this embodiment, the terminal system can dynamically load the modem according to the attributes of different hardware, realize adaptive switching between wifonly and LTE versions, and realize that the modem is cut out in software form when the current mode supports only WiFi mode. It should be understood that since the start-up and monitoring of the modem, sp, dp and other systems are all guided by the modem control, in order to realize the shielding of the modem without affecting the start-up of the sp, dp and other systems, the control of the modem cannot be completely shielded. Because the WiFi software version stops the modem from serving, the modem-related device nodes still exist. Although it will not affect the modem from stopping service, it will still send related instructions and occupy memory. Therefore, in this embodiment, deleting the modem-related device nodes can further realize WiFi. Optimization of software version.
