Huawei Technologies today announced that it has successfully completed commercial technology testing for ‘VoIP over HSPA’ in Shanghai in conjunction with QUALCOMM. They claim it is the industry’s first VoIP service display with an ALL IP end-to-end solution that is based on a commercial chipset and IMS-based system platform. Being 100% end-to-end IP is part of the beauty and promise of IMS and apparently Shanghai is leading the way. I'm in the process of testing/reviewing a carrier-class IMS testing tool from Navtel Communications that Huawei might find useful. Navtel's tool was designed for IMS and can handle 256,000 unique SIP or NCS (cable/MSO VoIP) subscribers, 374,000 unique endpoints for H.248 ( BGF), 128K Unique RTP streams for SIP and NCS, and 192,000 RTP streams for H.248 ( BGF).
In any event, I should explain that High-Speed Packet Access (HSPA) is a mobile data packet technology of Wideband Code Division Multiple Access (WCDMA) that allows mobile phone users to enjoy high-quality, richer voice communications at a low price.
According to their release, Huawei put IP voice into an HSPA transfer channel, a technology called ’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. To date, Huawei has already completed commercial testing of ‘VoIP over CDMA（Code-Division Multiple Access）’, ‘VoIP over WiMAX（Worldwide Interoperability for Microwave Access）’ and ‘VoIP over HSPA（High-Speed Packet Access）’ and passed interoperability testing with IMS（IP Multimedia Subsystem）.
‘VoIP over HSPA,’ which is based on the 3GPP IMS standard, allows operators to enrich their current business models by replacing circuit-switched calls, as well as delivering services with new business models, such as offering free Internet-quality calls. ‘VoIP over HSPA’ is an operable mobile technology that ensures high voice quality and quality of service (QoS) while the billing and security can be completely controlled by the carrier.
Huawei and QUALCOMM’s testing indicated 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.

I've suggested that Skype delayed its client on Symbian until HSxPA will come in real world. You can read my post here: http://symbiancorner.blogspot.com/2007/08/native-skype-voip-client-application-on.html
Hmm interesting, looking foward to your review
