Beschreibung
IMS Multimedia Telephony service has been standardized in 3GPP asthe replacement of the circuit switched telephony service incellular networks. The multimedia telephony service consists ofseveral service components such as voice, video and text.'IMS Multimedia Telephony over Cellular Systems'provides a comprehensive overview of the service that will enableenriched telephony for mobile users. Enriched telephony fulfils theuser's desire to communicate in new ways, for example bysharing pictures and video clips.
In addition to an overview of the Multimedia Telephony service,the book focuses on the modern media processing methods, whichallows the quality of the packet switched voice and video telephonynot only to match but also possibly exceed the quality of circuitswitched telephony. Such key components as adaptive jitterbuffering and adaptation of conversational media are explained indetail.
Key features:
* Detailed description of how Multimedia Telephony sessions areset-up and controlled
* Analysis showing the capacity and quality of VoIP andMultimedia Telephony in cellular networks
* Coverage of other IMS services such as PoC specified by 3GPPand OMA
* Description of suitable QoS and radio bearers for MultimediaTelephony
* Explanation of the modern radio interface, especially HighSpeed Packet Access, which is based on concepts such as linkadaptation and fast hybrid ARQ
The possibilities for the current and future standards coveredin this book make it an indispensable resource for engineers,designers and researchers in VoIP, telecommunication companies anduniversities teaching and conducting research intelecommunications. It will also be of interest to managers needingan in-depth knowledge of the engineering and key issues of thiscomplex technology, and students aspiring to develop a career inthis area.
