IVVR Farming for 3G Streaming Live Video Services

The 3rd Generation Video Telephony value added service providers have seen the benefits of centralizing equipment as it reduces maintenance costs (everything is now managed as a whole) and increases equipment use, since equipment (such as Video IVR ports) can now be shared among 3G operators, thus lowering the overall number of required ports. Wireless telecommunication operators are rolling out UMTS / 3G networks and providing broadband internet speeds and ability for service providers / customers to access IVVR rich services such as video streaming and mobile TV. Live Video like TV contents are delivered thru RTSP streaming servers and prerecorded MP4 / VXML contends thru NAS systems. The proposed architecture basically supports any single point of failure. Thus, videocalls will continue to be processed even after a failure.   The following high availability features are: Dual SIP routers: OpenSER […]

3G-UMTS Mobile Phone Standards and Technology

Thanks again to Christoph K. for this new article about 3G Telephony Technology 3G systems were designed with the notion of enabling a single global standard to fulfil the needs of anywhere and anytime communication (Etoh). Compared to 2G (Second generation mobile networks, services and technologies) systems, 3G systems focus more on multimedia communication such as video conferencing and multimedia streaming. ITU (International Telecommunication Union) defined IMT-2000 as a global standard for 3G wireless communications and, within this framework, 3GPP (3rd Generation Partnership Project) developed UMTS (Universal Mobile Telecommunications System) as one of today’s 3G systems. W-CDMA (Wideband Code Division Multiple Access) is the main 3G air interface for UMTS (Holma and Toskala) implementing various person-to-person, circuit-switched services such as video telephony. The high-level UMTS network architecture from 3GPP-R5 is described in documents from its Technical Specification Group in the […]

Sharing Video IP Cameras with VXI* VoiceXML for 3G-UMTS videocalls and VoIP SIP

We are please to present a new update of the IP Cam Xtras addon for VXI*, one of most interesting feature for 3G/SIP videocalling services is to access to an IP camera. This module allows to code with VoiceXML a hosted video portal to access to many IP cameras in multi-session mode. This mean many users can share any camera connected to the service. 3G videocall’s advantages: No 3G data contrat required (you don’t need Internet plan for your mobile phone) No previous software  application/ SMS instalation required No specific mobile phone setup and configuration, just make a videocall! Video streaming optimized for Mobile Wireless Communication Real-time bidirectional  mode always available Works with all 3G mobile phones (videocall enabled, most of them are today) Works with all 3G UMTS wireless operators Works in roadming mode thru another 3G UMTS operator […]

3G-UMTS video wireless network coverage ready but lack of services

  Be ready for 3G-UMTS technology don’t represent is very special innovative situation today for countries. Past days, we was traveling to Mexico and i discover that 3G wireless network coverage is very good there in most small or big cities of the Yucatan’s region. Main local wireless operators as Movistar, Telcel and Telmex; even in the road all wireless antennas were 3G enabled! Videocall is possible it’s not a far dream… Here our driver Victor show us his own Nokia N95 3G mobile phone, ready for videocall… ready for Internet, ready for a lot of things but there is a lack of videocall services like in most other countries, Operators only provide very basic services and promote voice and data… no significant value added video services yet available.  This is your opportunity here in Mexico and in most of […]
