The card pool management system includes a card loading device. The card-carrying device comprises a plurality of SIMBank (the SIMBank is a device for inserting and placing a physical card or an eSIM card in the card-carrying device). Each SIMBank comprises a remote authentication module and a SoftSIM storage module. The card-carrying device supports an eSIM card, a physical card, and SoftSIM storage. The SIMBank supports the eSIM card to use the eSIM as a traditional physical card, and is authenticated by the SIMBank, so the remote authentication module can be used for remote authentication of the eSIM card, the physical card and the SoftSIM.
The card pool management system also includes a configuration manager and an LPA manager for eSIM services, the LPA manager to request card issuance from a standard SM-DP + platform. The configuration manager provides a user interface to manage SIM card information and status on the card-carrying device.
The data center is used for storing and centrally managing SIM card files, SoftSIM card files, eSIM card files (eSIM on non-card-loading equipment) and authentication modes automatically reported by the card-loading equipment. The eSIM card file on the card-off-load device is actually generated and managed by SM-DP +, and the data center has only card information of the eSIM card. Such as ICCID, IMSI, PLMN, card registration network, SM-DP + address of the card, etc. The authentication mode comprises terminal local authentication, cloud card platform authentication service authentication and SIMbank authentication. And the cloud card platform authentication service module completes the remote authentication of the SoftSIM. And under the SIMbank authentication mode, the authentication service module on the SIMbank completes the authentication of the physical card or the eSIM card and the SoftSIM card on the SIMbank.
According to the unified cloud card issuing method and the mixed cloud card service system, the optimal card distributing strategy of the terminal is determined through card distributing operation of different terminal types, cloud card distribution of different terminal equipment types is achieved, and a subsequent authentication mode is determined according to the terminal equipment types and the cloud card types.

Each SIMBank is assembled from different single board modules. Each single board can be integrated by a plurality of physical card slots or by a plurality of eSIM chips. The card-loading device 3 hardware can support the insertion and reading of a traditional physical card, and can also support the insertion of an embedded eSIM card slot and an eSIM card. When card files are downloaded and installed to an eSIM card on the SIMBank, the SIMBank reads and uploads card information and card files to the data center while the eSIM card is used as a legacy SIM card.
The cloud card platform 1 includes a cloud card service module 12, a policy module 13, a query module 14, a card issuing module 15, an eSIM service private SM-DP + platform 16, an authentication service module 17, and a connection manager 18.
The eSIM RSP is an eSIM signing management platform and comprises SM-DP + platforms of a plurality of different trusted certificate issuers.
The cloud card service module 12 is configured to obtain a terminal type of the requesting terminal, and determine a cloud card type and a certificate type that can be used by the terminal.
The policy module 13 is configured to determine a card distribution policy according to the terminal type, the cloud card type, and the certificate type.
The query module 14 is configured to search card resource information from the card-splitting operation data center according to the terminal type and the cloud card type.
