Ericsson Review, no. 01, 2008

The purpose of Ericsson Review is to report on the research, development and production achievements made in telecommunications technology at Ericsson. The journal is published three times a year.


Communication Services - The key to IMS service growth
IMS gives developers a tremendous range of opportunities to create services. This freedom is being used to craft timely, attractive, innovative and differentiating applications as well as standardized services. This, in turn, ensures that operators continue to play a valuable and profitable part in delivering voice, video, text, and more to the consumer community.          
     
Chat on phone, not a PC clone - IMS-based mobile community service
Delivering a great user experience in the simplest possible way is often a complex task. To succeed, one must understand and translate user needs, expectations, technical opportunities, and constraints into adequate design. Ericsson has applied these criteria to an IMS-based service for mobile communities. The service concept, which supports IM and VoIP communication, uses the IMS core system, PGM, application servers, and media resource function processors.

              
MIDP3: Mobile device media power train
The third generation of Java Micro Edition MIDP has been designed from the ground up to work with any multimedia Java API and promises to deliver the most comprehensive mobile middleware ever. It articulates interoperability in areas where Java must integrate with native device environments and augments a more consistent end-user experience through several significant enhancements to the user interface.

 

Reducing CO2 emissions from mobile communications - BTS Power Savings and Tower Tube
Climate change is high on the global agenda and Ericsson is strongly committed to doing its part by reducing the environmental impact of its operations and by providing sustainable solutions to customers and society. Two specific examples of Ericsson's energy-reduction solutions are BTS Power Savings, and the Tower Tube concept for building telecom sites.

 

HSPA Evolution - Boosting the performance of mobile broadband access
HSPA Evolution is currently being standardized by 3GPP in Releases 7 and 8 of the WCDMA specification. The aim is to further enhance the performance of WCDMA systems through higher peak rates, lower latency, greater capacity, increased battery times, better support for VoIP, and improved multicast/broadcast capabilities.

 

Mobile TV over 3G networks - Enablers and service evolution
User interest in mobile TV services is growing thanks especially to the rapidly evolving multimedia capabilities of mobile terminals. Mobile operators are thus eyeing mobile TV services both as a new source of revenue and as a way of increasing customer loyalty. Built-in support of unicast and broadcast transmission is a key component of mobile TV solutions that capitalize on the capabilities of 3G networks.

 

Ericsson's User Service Performance Framework
Ericsson is securing predictable user service performance by reusing proven methods and tools. Among other things, this entails setting requirements at the system service level using input from user studies; defining system service KPIs that reflect the user point of view; verifying system service performance values in a test environment with relevant network load; verifying the system service assurance architecture and reports for the defined system service KPIs; and providing system service audits and benchmarks.
