1. A method for management of resources of a chipcard connected to a communication terminal, the resources comprising electronic memory units, the method comprising:

transmitting, from the communication terminal, an application request and a module identification identifying the chipcard to an application management unit;

transmitting, from the application management unit based on the received application request, a first resource management instruction for making ready or releasing resources in the chipcard to a resource management centre external to the chipcard, the first resource management instruction comprising the module identification identifying the chipcard;

determining in the external resource management centre if sufficient resources are available in the chipcard identified through the module identification to meet requirements of the first resource management instruction;

transmitting a second resource management instruction from the external resource management centre via an external telecommunication network to the chipcard identified through the module identification;

making ready or releasing resources, in accordance with the received second resource management instruction, through a resource control mechanism in the identified chipcard;

transmitting a resource management confirmation from the identified chipcard via the telecommunication network to the external resource management centre concerning resources which have been made ready or released;

storing information in the external resource management centre about the resources made ready or released in the chipcard based on the transmitted resource management confirmation received by the external resource management centre, the information being stored assigned to the module identification;

transmitting a resource preparation confirmation from the resource management centre to the application management unit;

transmitting an application installation request from the application management unit via the telecommunication network to the chipcard;

installing an application in the chipcard through the resource control mechanism in accordance with the application installation request using the prepared resources; and

storing information in the application management unit about the installed application, the information being stored assigned to the module identification.
