Software Download Management for Reconfigurable Terminals in UMTS/FDD

This paper introduces a novel approach of software download management for reconfigurable terminals using common channels in WCDMA system. We introduce in this paper protocols, which enhance cellgrouping broadcast approach for software downloads that, are mainly used to reduce interference in interference limited CDMA based system. In addition, it gives the fundamental load based criteria in system level to divert software download traffic between common channels and dedicated channels, as it is enhanced by packet indexing based software download strategy. With introducing the concept of software download mode, the actions in this mode and protocols of inter-mode handover listed in the end of this paper give the realization of software download management in WCDMA system.
