A method to enhance the design of flexible network protocol stack to concurrently support multiple modular mobility protocols is based on the derived framework enabling the design of such a flexible reconfigurable terminal. It can further control at run time the mobility protocols and thus transparently operate more than one protocol simultaneously, for example, both macro and micro mobility protocols. A dynamic protocol database 180 stores the location of the various protocol modules in the memory 150. A single reconfiguration element is maintained in a Generic Mobility Components 130 and is controlled by an Event Identifier in the Generic Mobility Component Manager 110. The Event Identifier 114 is enhanced to process all incoming events and reconfigure the elements to the related part of the Protocol Database according to the relevant protocol the event is associated with. The resulting flexible architecture employs an enhanced protocol component design and may be implemented in numerous manners and platforms. A mobile terminal 100 with this architecture may move around and transparently connect to different access networks. It is further enabled to operate concurrently more than one protocol to fulfil various application scenarios and their requirements. This enables mobile terminals to become more intelligent and operate flexibly in a heterogeneous multi-access network environment with multiple protocol support.
