FIELD: communication.
SUBSTANCE: invention relates to devices for wireless communication networks, in particular, for keeping a subscriber identity module card in a standby state. For this purpose, the method includes receiving, by a terminal device, an enabling request, used for requesting simultaneous standby of a first subscriber identity module card, implemented on the basis of software, and the second subscriber identity module card, implemented on the basis of hardware, invoking a third-party invocation interface provided by an operating system of the terminal device, and performing interaction with a subscriber identity module card control module, through a subscriber identity module mobile equipment function of the third-party invocation interface, so as to complete a network access process of the first subscriber identity module card on the basis of a data file of the first subscriber identity module card. Besides, invention comprises keeping the both subscriber identity module cards at the same time according to the enabling request, wherein the second subscriber identity module card has already accessed a network. Wherein the completing a network access process of the first subscriber identity module card on the basis of a data file of the first subscriber identity module card comprises receiving, by the terminal device, an authentication request, sent by a network side device, reading key information in the data file of the first subscriber identity module card, generating authentication information according to the read key information, and sending the authentication information to the network side device to complete the network access process of the first subscriber identity module card.
EFFECT: technical result is simultaneous keeping a subscriber identity module card, implemented on the basis of hardware, in a standby state, and a subscriber identity module card, implemented on the basis of software.
