Operating system interface for use with multitasking GSM protocol stacks

A GSM transceiver for use in a GSM network comprising:

• a multilayer protocol stack for executing a plurality of asynchronous tasks which are encoded with a universal instruction set used for communicating between and synchronizing the tasks, said protocol stack comprising:
• a plurality of dynamics description parameters containing at least one frame delay and at least one frame advance, each frame delay and frame advance representing an integer multiple of a fixed time duration for a particular instruction to be scheduled in a frame, and
• at least one scheduler for scheduling instructions in frames based on the dynamics description parameters, each instruction being either delayed or advanced by the at least one scheduler by an integer multiple of the fixed time duration for that instruction contained in the dynamics description parameters;
• a multitasking operating system having a set of operating system instructions and providing prioritized execution of the tasks by execution of the operating system instructions;
• an operating system interface causing instructions of the universal instruction set to be carried out by the multitasking operating system so that each universal instruction of the universal instruction set is executed as a sequence of at least one instruction of the operating system instruction set, each instruction of the universal instruction set is generic and independent of the instructions of the operating system;
• and
• at least one processor controlled by the operating system to execute the asynchronous tasks.
