METHOD AND APPARATUS FOR REDUCING ERASING AND WRITING OPERATION TIMES OF SUBSCRIBER IDENTITY MODULE CARD FILES

摘要

A method and apparatus for reducing erasing and writing operation times of Subscriber Identity Module (SIM) card files are provided. The present technical solution uses the linear length-fixed files in the SIM card that are unusually used in some services, and pre-reads the linear length-fixed files into storage areas of a terminal, thus improves the running speed of a service system. With regard to the operation of erasing and writing on the SIM card in the operating of service system, the present technical solution performs storing at the memory card of the terminal first, and performs the operations of erasing and writing on the SIM card uniformly when a writing condition is satisfied. By the above method, the access times to the SIM card are reduced effectively, and the using life of the SIM card is prolonged.
