Abstract

A GSM transceiver unit (10), for use in a GSM network (84), having a multilayer portable protocol stack is disclosed. The multilayer protocol stack includes a hardware layer (204), a first portable layer (206) configuring the hardware layer and controlling communications to and from the hardware layer, and second and third portable layers (208) controlling communications to and from the first portable layer and utilizing the first portable layer for communications with the GSM network. The GSM transceiver unit (10) includes a dynamics description (202) containing at least one time delay with each time delay representing an integer multiple of a fixed time duration for a particular instruction to be scheduled and containing at least one time advance with each time advance representing an integer multiple of the fixed time duration for a particular instruction to be scheduled. The first portable layer has at least one scheduler (210, 212), with each scheduler being responsive to the dynamics description, for scheduling instructions in frames with 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. The hardware includes at least one processor (34, 76) for executing code implementing the at least one scheduler.
