Huawei and Qualcomm See Big Gains in "VoIP over HSPA"

Huawei Technologies completed commercial technology test of "VoIP over HSPA" in Shanghai in conjunction with QUALCOMM. The companies describe the project as the first ALL IP end-to-end solution that is based on a commercial chipset and IMS-based system platform.



For the project, Huawei put IP voice into an HSPA transfer channel -- a technique it dubs "VoIP over HSPA". The testing uses Huawei's UMTS/HSPA and IMS systems, including all RNC (Radio Network Controller ) base and all IP transmission system and QUALCOMM's MSM7200 chipset solution.



Previously, Huawei has commercial tested "VoIP over CDMA", 'VoIP over WiMAX and 'VoIP over HSPA (High-Speed Packet Access)' and passed interoperability testing with IMS.



Huawei and QUALCOMM said their testing indicates that 'VoIP over HSPA' increases the traffic capability by 50% in comparison with traditional voice communications technologies. If the migration is from 'VoIP over HSPA+' the traffic capability can be increased by 100%. Enhanced features such as uplink interference cancellation will enable further gains, achieving almost three times the capacity compared to current R99 systems.
