Apparatus for interoperating end-to-end quality of service in hetrogeneous networks evironment and method thereof

The present invention is an end-to-end quality of service in a heterogeneous network environment according to (QoS Quality of Service) linkage, and NAPI unit for processing the NSIS API (Next Steps In Signaling Application Programming Interface) in accordance with the requirements of the higher layer, the NAPI block and NSIS individual unit processes the NSIS protocol stack in accordance with the requirements, IP BS (Internet protocol Bearer Service) the IP BS pre-determined management and, NSIS message management 3GPP_CLASS (Third Generation Partnership Project Class) Universal Mobile (object and UMTS Telecommunication System) in a predetermined mapped configuration parameters of the QoS class thus coupled to the translation unit, and a UMTS BS (memory unit, said memory unit for storing software comprising a UMTS BS manager for managing the Bearer Service) of the It comprises parts of the processor to control the software. QoS, 3GPP, 3GPP_CLASS, signaling
