ABSTRACT:
A method is provided for use in a system. The system comprises at least one processor. A first operating system and a second operating system are processed in the processor. A first set of resources is controlled by resource services of the first operating system to be executed in the first operating system, and a second set of resources is controlled by resource services of the second operating system to be executed in the second operating system. To use a resource of the first set, a function call comprising information about the resource of the first set is formed in the second operating system. The function call is transferred to an interface block formed between the operating systems. In response to the function call, a service call on the basis of the information included in the function call is formed to start the resource service of the first operating system.
