Effective bandwidth calculating system for assure the QoS of real-time voice in Geostationary Orbit Satellite and method of resource allocation thereof

摘要

The present invention relates to a system for calculating an effective bandwidth for real-time voice quality guarantee in a geostationary satellite system and a resource allocation method using the same. More particularly, at least one user terminal generating voice traffic to be transmitted to the geostationary satellite system Voice traffic modeling unit 100 for modeling (UT, User Terminal) 10, multiplexing the modeled voice traffic received from the voice traffic modeling unit 100, and preset QoS (Quality of Service) requirements Receive downlink satellite resource allocation requests from a plurality of downlink satellite terminals (RCST) 200 and a plurality of downlink satellite terminals 200 that calculate an effective bandwidth based on the respective downlink satellites. Network control center (NCC) 300 for controlling communication by allocating satellite resources according to the effective bandwidth of the terminal 200 The present invention relates to an effective bandwidth calculation system for guaranteeing real-time voice quality in a geostationary satellite system.
