A communication control method is disclosed, including: connecting, by a small cell by using a built-in soft SIM card or an inserted SIM card, to a Uu air interface of a macro cell to access the macro cell; after receiving a broadcast synchronization signal of the macro cell, synchronizing, by the small cell, with the macro cell, and acquiring configuration information of the macro cell; and performing, by the small cell, system configuration for the small cell according to the configuration information of the macro cell. A SIM card is added to the small cell, so that the small cell can access a macro cell in a terminal form, which is equivalent to addition of a Uu air interface between the small cell and the macro cell. Therefore, configuration management, performance optimization, admissible subscriber configuration, and the like are implemented for the small cell by using this air interface.

A subscriber identification module (SIM) card detection failure recovery method for an electronic device includes that the electronic device identifies a card recovery scenario, where card recovery includes whether to power on a SIM card. A configurable timer is started based on the card recovery scenario. The electronic device periodically obtains, based on a time set by the timer, power-on information for powering on the SIM card. The electronic device determines a power-on condition of the SIM card based on the power-on information. If the power-on condition is met, the electronic device powers on the SIM card.
