Further, after the electronic device loads the configuration parameters, other initialization operations may be performed, so that near field communication is performed according to the configuration parameters.
According to the loading method of the near field communication configuration parameters, when the near field communication function is started, the variable value of the control variable corresponding to the near field communication function is obtained; when the variable value of the control variable is a first preset value, acquiring a configuration file of the near field communication function, and acquiring configuration parameters from the configuration file; by controlling the variable value of the control variable, that is, controlling the variable value of the control variable to be a first preset value, the configuration parameters are obtained from the configuration file to be loaded, so that the loading of the configuration parameters can be ensured, and near field communication is performed according to the configuration parameters.

For example, the electronic device can perform near field communication with an IC (Integrated Circuit Card ) card (bus card, subway card, etc.), so that services such as recharging, logging in, modifying information, etc. can be performed on the IC card. For another example, the electronic device may perform near field communication with a card swiping machine (bus swiping machine, subway gate, etc.), so as to perform operations such as payment, registration, etc. And the electronic device performs near field communication in different scenes, and the used (loaded) configuration files are different. Thus, one or at least two configuration files are stored at the electronic device, while the configuration file used when the near field communication function is turned on is the currently active configuration file.
When the electronic equipment starts the near field communication function, the electronic equipment records the configuration file which takes effect when the near field communication function is started in the log file, when the variable value of the control variable is a first preset value, the log file corresponding to the near field communication function is obtained, the effective configuration file is obtained from the log file, and the configuration parameters are obtained from the effective configuration file, so that the problem that the configuration parameters cannot be loaded due to the fact that the wrong and invalid configuration file is obtained can be avoided, and the accuracy of loading the configuration parameters is improved.
Further, the electronic device obtains the current time and the effective time of each configuration file recorded by the log file, and takes the configuration file corresponding to the effective time closest to the current time as the configuration file of the near field communication function effective when the near field communication function is started.
