APPARATUS FOR INTEROPERATING END-TO-END QUALITY OF SERVICE IN HETROGENEOUS NETWORKS EVIRONMENT AND METHOD THEREOF

摘要

In an end-to-end Quality of Service (QoS) interworking device in a heterogeneous network environment, the present invention provides an NAPI unit for processing NSIS API (Next Steps In Signaling Application Programming Interface) according to a request of a higher layer, and the NAPI block. NSIS entity part handling NSIS protocol stack, IP BS management part managing IP BS (Internet Protocol Bearer Service), 3GPP_CLASS (Third Generation Partnership Project Class) object and UMTS (Universal Mobile), which are predetermined in NSIS message. Telecommunication System) A memory unit for storing software including a translation unit for translating the parameters of the QoS class according to a predetermined mapping structure, and a UMTS BS management unit for managing a UMTS BS (Bearer Service), and coupled to the memory unit It includes a processor unit for controlling software. ; QoS, 3GPP, 3GPP_CLASS, Signaling
