Method and system for virtually spreading capacity of user recognizing module card

Abstract

The invention discloses a method and a system for virtually expanding the capacity of a subscriber identification SIM module card. The method comprises the following steps: a mobile phone transmits unique identity information of a storage card to an application server of the storage card; when the application server of the storage card determines that the received unique identity information of the storage card accords with storage card information which is prestored in the storage card, the unique identity information of the storage card is transmitted to the SIM card through the mobile phone; if the SIM card determines that the bound list information of the SIM card stored in the SIM card self does not contain the unique identity information of the storage card, a binding request message is transmitted to the application server of the storage card through the mobile phone and an OTA server; and the application server of the storage card receives the bound request message transmitted by the OTA server, and the storage capacity of the storage card is virtualized to the expanded storage capacity of the SIM card. With the method and the system, the application cost of multimedia service for a user of an operator is reduced; meanwhile, the operator can quickly and efficiently deploy and popularize value-added service conveniently, and the storage capacity and the communication speed for download application can be ensured.

Description

technical field [0001] The invention relates to memory technology, in particular to a method and system for virtually extending the capacity of a Subscriber Identification Module (SIM, Subscriber Identification Module) card. Background technique [0002] In mobile communication, SIM card is mainly used as a carrier of personal identity authentication and identification information at first, and also stores some personal data, such as phone book, short message, etc., and is generally used in combination with mobile phones to realize mobile communication. [0003] With the development of SIM card technology and e-commerce, it is the development trend of mobile communication to combine e-commerce and SIM card technology to expand user mobile communication services and realize multimedia service applications. For example, browse information, send emails, place orders for shopping, download music, movies, and watch videos online through mobile phones. It not only improves the pe...

Problems solved by technology

[0012] However, in the existing improved large-capacity SIM card scheme, a huge change has been made to the SIM card itself, especially the SIM card operating system and interface, which increases the complexity of the SIM structure; moreover, in order to be compatible with large-capacity SIM Cards, mobile phones also need to be improved accordingly. In this way, if users need to apply multimedia services, they first need to choose to buy a large-capacity SIM card to replace the existing SIM card. The mobile phone of the communica
