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.
