METHOD OF SCHEDULING PACKETS FOR TRANSMISSION OVER A UMTS NETWORK

摘要

A method of scheduling packets for transmission over the air interface of a UMTS Terrestrial Radio Access Network (UTRAN) in the case where a pair of Radio Network Controllers (RNCs) are acting as separate serving and controlling (drift) RN Cs for a mobile terminal. The method comprises sending from the controlling RNC to th e serving RNC, allocated scheduling priorities together with packet sizes accepted for transmission with those priorities by the controlling RNC. Subsequently the serving RNC send to the controlling RNC, packets of sizes accepted by the controlling RNC together with respective allocated priorities.
