Huawei Puts VoIP over HSPA Print E-mail

Huawei Technologies (www.huawei. com) has successfully completed commercial technology testing for VoIP over HSPA (high speed packet access) in conjunction with QUALCOMM. The demonstration is the first VoIP service display with an all IP end-to-end solution based on a commercial chipset and IMS-based system platform. Huawei put IP voice into an HSPA transfer channel, using the company’s UMTS/HSPA and IMS systems along with QUALCOMM’s MSM7200 chipset solution. Testing indicated that VoIP over HSPA increased traffic capacity over 50 percent in comparison with traditional voice communications techniques, with enhanced features holding the potential to achieve over three times the capacity as current systems.

In the silicon world, value-added is defined by the ability to accommodate any eventuality. Israel’s Surf Communications Solutions (www.surf-com.com) is pitching a DSP chip multimedia processing solution, the Surf DSP-12TM, at the convergence market on the premise that the platform can handle the multimedia requirements of multi-play carriers. As voice, data, and video-processing requirements grow in as yet undetermined ways, seamless chip solutions that allow for all bases to be covered are fast becoming the standard. Octasic Inc., a media-processing solution provider based in Montreal, Canada, (www.octasic.com), has also recently rolled out a multi-core gateway DSP platform for voice, video, and data over IP applications. According to the company, the Vocallo platform emphasizes a “comprehensive solution for current and future media gateways.” And that’s the point–silicon has to be built for any purpose. No longer will carriers have the money or the time to anticipate exactly where their customers will take them. Thus, the fundamental processing power behind those services has to be flexible.

Securing the IP Enterprise

Mobility is one of the hot buzzwords in IP networking spaces. Mobile workers, mobile devices, and ubiquitous service coverage present the holy grail of the workanywhere professional. This broadening of access, coupled with integration of VoIP and video services, creates a problem for enterprise security managers. Deperimeterization of the network has raised the bar on what it takes to effectively protect an enterprise. Enterprise businesses have implemented traditional security mechanisms ranging from firewalls and session border controllers to intrusion detection and prevention systems. They worked when the perimeter was a single connection to the Internet. In today's business environment, with highly mobile professionals connecting via all manner of devices, the perimeter is both nowhere and everywhere. But it's no longer a fixed, visible point in the network topology.
