Title:
SIM CARD COMMUNICATION CIRCUIT, RELATED APPARATUS, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/012020
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an SIM card communication circuit, a related apparatus, and a control method. The circuit comprises a processor, a switch unit, a first card slot, and an ESIM chip. Of the switch unit, an input end, a first output end and a second output end are respectively connected to the processor, the first card slot and the ESIM chip. The processor is used for controlling, when receiving a first message, the switch unit to select connection to the first card slot; or the processor is used for controlling, when receiving a second message, the switch unit to connect to the ESIM chip. In this way, by means of the switch unit, sharing of an SIM interface is realized, thus realizing both ESIM card communication and physical SIM card communication. The processor does not need addition of an interface, so that the size and the occupied area are not changed. In addition, the circuit, with or without an ESIM chip added thereto, can use the same processor, and thus co-specification design facilitates production.
