Beschreibung
This book addresses the needs of engineers and technicians who need to analyze the signaling messages within and among complex Next Generation Networks.
In that respect, some but not all emphasis is on IMS-based mobile networks as standardized by 3GPP for the enabling of IP-based multimedia services.
The technical focus of the book lies on the understanding of SIP/SDP-based session control signaling among SIP-servers and between SIP-servers and SIP-terminals.
Especially the perspective of the SIP-terminals (UA) is covered in detail. And intentionally the book does not focus only on standard voice calls but also covers other session types like instant messaging, gaming or VoD.
The student is confronted with various SIP/SDP-related and practice-oriented questions and exercises to gain the maximum output from the book.
After a comprehensive review of NGN’s, SIP and SDP and other protocols like IPsec, MSRP or DIAMETER the book focuses on a detailed description of the various SIP- and SDP-aspects (Network Elements, SIP/SDP-Terminology, SIP-Timers) and on advanced SIP/SDP-operation.
The latter part deals among others with essential issues using SDP-preconditions and, very important, the handling of ungraceful session releases.
The book continues with the presentation of typical SIP-scenarios for different applications like registration, video or voice call setup, application server access and interworking between SIP and ISUP.
One chapter is dedicated to 3GPP-based and IMS-enabled mobile networks and the related SIP- and SDP-specifics.
