User identification module and method for downloading and storing application data

Abstract

The invention provides a user identification module and a method for downloading and storing application data. The method comprises the following steps of: establishing a circular downloading area in a storage space of the user identification module; deleting one or more application data from the circular downloading area and recovering and storing the storage space of the deleted application data if the residual space of the circular downloading area is insufficient to store downloaded application data and the total space of the circular downloading area is enough to store the downloaded application data when the downloaded application data need to be stored in the circular downloading area, wherein the total size of the deleted application data is larger than or equal to the size of thedownloaded application data; and allocating a space in the circular downloading area to store the downloaded application data. The invention can ease the problem of limited storage space of the user identification module.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a user identification module and a method for downloading and storing application data. Background technique [0002] The existing user identification module is to download the application data (usually but not limited to the application menu) to the SIM card (or other user identification modules) by the application download system via wireless (SMS, GPRS, etc.) or wired (WEB) , Store application data in SIM card and generate application menu. [0003] Because of the numerous applications of the Internet of Things, a user has a large number of Internet of Things, which far exceeds the number of applications in the current era of human-to-human communication. It is preliminary estimated that the Internet of Things will have 30 times that of humans, and every object needs The user uses a simple, low-cost, and portable tool for unified control. The SIM card has obvious advantages in ...

Problems solved by technology

[0005] However, due to the limited space of the SIM card, it is unrealistic to download all IoT applications to the card

The SIM card only supports the automatic allocation of application download space or the allocation specified by the system, and does not support automatic recovery of storage space. When the downloaded storage space is full, if you want to continue downloading new service menus, the user must actively delete the application data from the card. Or the operator remotely PUSH deletes the application data to release the storage space, does not support the automatic recovery mechanism of the application data storage space, which often brings great difficulty and trouble to the user, because the user does not know which application data should be deleted, It can meet the download space requirements of new applications. This situation will inevitably bring obstacles to the promotion of applications such as the Internet of Things that require more business application space. It cannot meet the space management requirements of many applications in the mobile communication field such as the Internet of Things, and the user experience is poor.
