Abstract
The present invention provides, for use in telecommunication systems, a system and method enabling implementation of dynamic memory management in a subscriber identity module via an application or management system stored in the subscriber identity module. The memory regions in the subscriber identity module can be dynamically allocated to store or accommodate customers' and service providers' own applications, and the amount of information that the system operator need to store relating to the memory structures of and stored applications in subscriber identity modules that it owns or controls is significantly reduced.
Claims11
A method for managing a memory space of a subscriber identity module in a telecommunication system that includes a management system and a mobile station to which the subscriber identity module is connected, comprising the steps of:
- dividing the memory space of the subscriber identity module into a plurality of sections for storage of applications in said memory space sections;
- and
- dynamically allocating the memory space of the subscriber identity module by dynamically assigning individual ones of the plural memory space sections for storage, in said plural memory space sections, of applications of at least one of an operator, a service provide and a subscriber of the telecommunication system.
A system for managing a memory space of a subscriber identity module in a telecommunication system that includes a management system and a mobile station to which the subscriber identity module is connected, said system comprising:
- the memory space of the subscriber identity module being divided into a plurality of sections for storage of applications in said memory space sections;
- means for dynamically allocating the memory space of the subscriber identity module by dynamically assigning individual ones of the plural memory space sections for storage, in said plural memory space sections, of applications of at least one of an operator, a service provide and a subscriber of the telecommunication system.
In a subscriber identity module that includes a data processing device, a storage device connected to the data processing device for defining a memory space of the subscriber identity module, a data transfer device connected to the data processing device, and an interface for transfer of information between the subscriber identity module and a telecommunication system mobile station to which the subscriber identity module is connectable,
- means for dynamically allocating the memory space of the subscriber identity module for storage in the memory space of applications of at least one of an operator, a service provide and a subscriber of the telecommunication system.
