Thomson connects IP to 3G, expands VoIP options
Thomson has debuted a gateway designed to integrate IP networks and 3G mobile services, allowing 3G mobile and fixed IP devices to share video.
The Cirpack 3G Video Calls Gateway connects mobile networks and IP/IMS-based networks by integrating the 3G video protocol (H.324m) with the SIP VoIP protocol. Service providers will be able to set up multimedia services including calls, video blogging, and even live television access. Operators can use the system to begin an evolution to full IMS, Thomson said.
"Operators know that their subscribers are excited by the prospect of video calls to fixed and mobile devices, as well as other added-value services like video blogging," said Tiaan Schutte, general manager of the software services platform at Thomson.
One of the barriers to 3G mobile video has traditionally been the considerable connection delay when placing calls, due to the need to exchange a number of messages to establish parameters. The Cirpack 3G Video Calls Gateway solves this, Thomson said, by implementing the Windowed Numbered Simple Retransmission Protocol, which bundles all signaling into a single batch and dramatically improves call set-up time.
Thomson simultaneously announced the new Cirpack Session Border Controller (SBC) to provide access and interfacing for the growing number of voice over IP services.
With many operators now using softswitches to provide local loop VoIP and advanced telephony services, there is a growing requirement to interconnect networks over IP. However, Thomson explained, this IP connectivity requires careful protection from denial of service attacks, as well as advanced security functionality, such as topology hiding and secured call control.
Separately, Thomson announced that two of its IP phones for the business market are interoperable with Alcatel-Lucent’s VoIP platform. Thomson’s business IP phones are now compatible with most major VoIP platforms, the company said.
Thomson’s ST2022 and ST2030 business IP phones are now interoperable with the new version of Alcatel-Lucent's Omni-PCX Enterprise PABX, Release 9.0. With the Auto-Provisioning System (APS) in Alcatel-Lucent’s Omnivista 4760, installing the Thomson ST2022 and ST2030 IP phonesno longer requires any individual configuration, Thomson said.
