Management method and management system of security domain storage spaces as well as multi-application open platform device

Abstract

The invention provides a management method and a management system of security domain storage spaces as well as a multi-application open platform device. The management method of the security domain storage spaces comprises the following steps: when new applications need to be downloaded in an intelligent card, obtaining the configuration requirement spaces and the space-sharing condition parameters of the new applications; obtaining the available storage spaces of a security domain in the intelligent card and the space-sharing condition parameters of the downloaded applications; using a preset dynamic allocation strategy to allocate the storage spaces for the new applications and the downloaded applications in the security domain of the intelligent card according to the configuration requirement spaces and the space-sharing condition parameters of the new applications as well as the available storage spaces of the security domain in the intelligent card and the space-sharing condition parameters of the downloaded applications. The security storage spaces in the intelligent card can be dynamically allocated and managed, so that the security domain storage spaces in the intelligent card are effectively utilized.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method, system and multi-application open platform device for managing storage space in a secure domain. Background technique [0002] With the rapid development of mobile communication technologies, near field communication (Near Field Communication, NFC) mobile phones have been more and more widely used. When using an NFC mobile phone, the user generally uses the NFC mobile phone to download the card application from the trusted service management (Trusted Service Management, TSM) platform (also known as the multi-application open platform) to the security chip (or security domain) through OTA , and then use the app after installation. [0003] In the prior art, there are generally two types of occupied storage space in the secure domain used by NFC card applications: a stable type and an unstable use type. Among them, the storage space of the sta...

Problems solved by technology

Therefore, when the user wants to download a new application, although some storage space is not used, the system will still prompt that there is insufficient space, so that the user cannot download and install the new application

It can be seen that the resource allocation method in the prior art seriously reduces the utilization rate of the allocated space, which is not conducive to the effective utilization of the storage space in the NFC card

With the increasing number of applications in NFC cards, the above resource allocation method will not be conducive to the download, installation and use of applications, reducing the success rate of installation of various applications, and will often report serious errors during the use of applications. phenomenon, which in turn will seriously affect the user experience
