Abstract :
This paper presents air interface capacity simulations for VoIP (voice-over-IP) over 3GPP Release 7 high speed packet access (HSPA) networks. The results show that 3GPP HSPA is able to provide VoIP spectral efficiency which is higher than the spectral efficiency for circuit switched voice calls with the same end-to-end quality. The high VoIP efficiency can be attributed to the packet optimization features in 3GPP Release 5, 6 and 7 specifications, to the advanced mobile receiver algorithms and to the VoIP optimized radio network algorithms. The studies also show that HSPA mobility solutions fulfil VoIP requirements with synchronous handover even if HSDPA does not use soft handover
