A mobile wallet client, its application processing method, and terminal equipment

Abstract

Embodiments of the invention provide a mobile phone wallet client and an application processing method thereof and a terminal device. The method comprises the following steps: determining an application which needs to be migrated and is arranged in an SIM card having a mobile phone wallet payment function; after carrying out encryption on the application and data of the application, storing the encrypted application and data to other storage mediums of a terminal where the SIM card belongs; and releasing the SIM card space occupied by the application. According to the scheme, when the SIM card space is full, the application and data on the SIM card are moved to other storage devices; and in the transfer process, safety of the application and the data is ensured.

Description

technical field [0001] The invention relates to the field of data services, in particular to a mobile phone wallet client, an application processing method thereof, and a terminal device. Background technique [0002] Such as figure 1 As shown, the traditional telecom SIM card has a single application and function, and generally includes functional areas such as VCC, RST, CLK, IC_DP, GND, SWP, I / O, IC_DM, etc. The available space for the user is 64K, which is used to store the phone Book, text message and other files, the applications of this kind of SIM card, such as phone book and text message, are single telecommunication applications. [0003] With the development of mobile payment, NFC-SWP SIM card has gradually entered the market. This is a multi-application card with the function of mobile wallet and supports dynamic download of applications, such as figure 2 As shown, including VCC, RST, CLK, IC_DP, GND, SWP, I / O, IC_DM and other functional areas, this kind of SIM...

[0004] However, the effective utilization of NFC-SWP SIM card space has become an important issue. The current NFC-SWP SIM card leaves 300K space for users, and an application occupies about 40K. If users download more applications, the card space will be insufficient.

[0005] Current solutions such as image 3 and Figure 4 As shown, among them, image 3 Schematic diagram of the download process for the application of the SIM card, Figure 4 It is a schematic diagram of the application deletion process of the SIM card; when the card space is insufficient, the user must delete the existing application before downloading the new application, and when deleting the existing application, the process takes a long time and needs to go through the TSM of the operator or SP ( TrustService Management (TrustService Management, Trusted Service Management) deletes an application, which is extremely risky; secondly, when deleting an existing application, the data of the application must be cleared, such as the balance of the wallet, and the application cannot be deleted without clearing the balance; thirdly, when the user needs to use the deleted When using the application, you must download the application from the TSM of the operator or SP, and make personalized settings, resulting in a waste of network resources and platform resources.
