Memory space is variable occupancy.Fig. 1 is the schematic diagram of security domain memory space of the prior art, as shown in figure 1, nfc card
Typically there are three kinds using the distribution resource space type of used security domain memory space：Minimum Free Space（Minimum is empty
Between）, the actual space distributed（Reserved spaces）With quota space（Quota spaces）.Wherein, Minimum spaces refer to pair
When download request is initiated in the nfc card application, the minimum free memory in card；Reserved spaces are that system is described
The memory space that nfc card application actually distributes；And
Quota spaces are extension storage space of the system for nfc card application distribution.Generally, Quota spaces
More than Reserved spaces；Moreover, generally, the only actual memory space of Reserved space holds, and
Minimum spaces and Quota spaces are then not take up actual memory space.As shown in figure 1, the oblique line portion in Fig. 1 is
Minimum spaces, R1, R2 and R3 are respectively the Reserved spaces of first, second and third application, and Q1, Q2 and Q3 are respectively the
First, the Quota spaces of two, three applications.

The Reserved spaces for distributing to the application are stored；If the data that the size deficiency storage in Reserved spaces newly creates
File, the data file that the Quota spaces storage for distributing to the application can be used newly to create；If distribute to the application
Quota spaces are also not enough to complete the storage and installation of the data file of the new establishment, and resource allocation failure, the application will occur
Partial function will be unable to be continuing with.
Therefore, according to above-mentioned resource allocation methods mode, the unique of security domain memory space is discharged in the prior art and is done
Method is to delete mounted application in nfc card.
From the foregoing, it will be observed that in existing all kinds of technical schemes, fixed space distribution principle is used for each application.By
In to apply the memory space that distributes be fixed by each, therefore for some mounted applications, although system
Corresponding Reserved spaces are assigned with for it, but the instream factor of the memory space distributed is very low, and TSM platforms
It is occupied that the allocated memory space in the part will also be recorded.So when user wants to download new application, although some deposit
Storage space is simultaneously not used by, but system can still prompt insufficient space so that user can not download, install new application.Thus may be used
Know, resource allocation methods of the prior art seriously reduce the utilization rate of allocation space, and be unfavorable for memory space in nfc card has
Effect utilizes.With becoming increasingly abundant for the application in nfc card, above-mentioned resource allocation methods will be unfavorable for download, the installation of application
With use, reduce the installation success rates of various applications, and application also will usually occur using process report an error it is serious
