MULTIPLE ABSTRACTION LAYERS WITHIN A COMMUNICATION DEVICE

摘要

In a method of processing data in a communication device operating in a heterogeneous communication network, data is transferred between a first communication interface within the communication device and an upper protocol layer via a first abstraction layer (AL) processing unit. The first AL processing unit is dedicated to the first communication interface. Additionally, data is transferred between the first AL processing unit and a second AL processing unit within the communication device via an interface between the first AL processing unit and the second AL processing unit. The first AL processing unit is dedicated to a second communication interface within the communication device.
