Your media everywhere, anytime. This summarizes end-user expectations when ever-wider broadband and ever-lower flat-rate tariffs combine with users’ thirst for digital content.
This article presents the main concepts of HSPA Evolution (high-speed packet access evolution), which is currently being standardized by 3GPP in Releases 7 and 8 of the WCDMA specifi cation. The aim of HSPA Evolution is to further improve 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.
The authors briefl y cover MIMO, higher-order modulation, protocol
optimizations, optimizations for VoIP, improved multicast/broadcast, and advanced receivers. They also describe a variety of features (such as multicarrier operation) that will boost performance even further in subsequent releases of the WCDMA specifi cation.

IMS multi-access (IMA) gives non-IMS-capable devices access to the IMS core network and services. It thus enables operators to provide IMS to the billions of GSM and ISDN terminals that are already in operation.
The Mobile Service Architecture (MSA) specifies a standardized set of APIs, which allows developers access to various capabilities – from sending SMS messages to address book information – on mobile phones.
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 an adequate design.
The success of IMS will largely depend on the availability of new services in end-user equipment. Strong focus on terminals is thus especially important to ensure that IMS services remain independent of access and terminal type.
Ericsson and Sun have teamed up to launch the Sun-Ericsson application competition, a contest designed to encourage innovation among developers and foster the creation of next-generation mobile and internet services.
Enhanced technology and new ways of charging for location-based services are producing new business opportunities for operators and service providers.
Live demonstrations of end-to-end mobile service creation using the SIP (Session Initiation Protocol) and IMS (IP Multimedia Subsystem) were greeted with ringing applause at JavaOne.
To exploit new business opportunities in the area of IPTV, the service must evolve from “TV over IP” into an interactive, personalized application that runs on several devices and can easily be integrated with other services.
