Embodiment 1

[0023] This embodiment provides a method for a smart card to support multi-operator number switching, the method includes the following operations:

[0024] When the user selects a number by setting the STK menu, the smart card judges whether the number selected by the user is the current number;

[0025] When the number selected by the user is not the current number, the smart card will search for the data file corresponding to the operator to which the number selected by the user belongs from the storage location of the data files of each operator stored in advance, and copy the GSM directory of the smart card to the directory of the operator. The data file can be replaced with the found data file;

[0026] Among them, the operator's data files include network data files and personalization data files, the network data files include operator name (SPN), preferred roaming list (PRL) and LOCI content files, and the personalization data files include international mobile Subsc...

Embodiment 2

[0034] This embodiment provides a smart card that can realize the solution of Embodiment 1 above, which at least includes the following units.

[0035] A judging unit, when the user selects a number by setting the STK menu, judges whether the number selected by the user is the current number;

[0036] The processing unit, when the number selected by the user is not the current number, searches for the data file corresponding to the operator to which the number selected by the user belongs from the storage locations of the data files of each operator stored in advance, and transfers the GSM directory of the smart card and the operator The data files in the directory are replaced with the found data files;

[0037] Wherein, the data files of the operator include network data files and personalization data files, the network data files include the operator name (SPN), preferred roaming list (PRL) and LOCI content files, and the personalization data files include IMSI, ICCID, PIN...

Abstract

The invention discloses an intelligent card and a method of the intelligent card for supporting switching of multi-operator numbers, and relates to the technical field of intelligent cards. The disclosed method comprises that: when a user selects the number via setting an STK menu, if the intelligent card judges that the number selected by the user is not the current number, a data file corresponding to an operator to which the number selected by the user is attributed is searched in storage positions of the data files of each operator stored in advance, and a GSM directory of the intelligent card and the data files under an operator directory are substituted by the searched data file. The data files of the operators comprise a network data file and an individualized data file. The network data file comprises SPN, PRL and LOCI content files, and the individualized data file comprises IMSI, ICCID, PIN1, PIN2, PUK1, PUK2 and KI files. The invention also discloses one intelligent card. The card can be switched between different network operator numbers via switching of operator network data between the different numbers by the technical scheme of the application.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a smart card and its method for supporting multi-operator number switching. Background technique [0002] In 2013, the Ministry of Industry and Information Technology issued a policy to support the entry of private enterprise funds into the telecommunications industry, and virtual operators were born from this. The current virtual operators can either sign a contract with China Unicom or China Mobile. Users go to the business hall of the virtual operator to handle business, that is, they can choose the network of China Mobile or the network of China Unicom. However, in order to reduce procurement costs, virtual operators often only purchase a certain type of SIM card from card manufacturers. Therefore, how to realize the switchover of carrying numbers of two different operators in one SIM card has become an urgent problem to be solved. [0003] At present, one card with tw...
