Nokia Siemens Networks launches books on LTE and IMS


Collaborates with industry to offer a holistic view on the topical issues of LTE and IMS

Espoo, Finland - Experts from Nokia Siemens Networks have introduced two new books ‘LTE for UMTS’ and the 3rd edition of ‘The IMS’. LTE for UTMS has been authored by 30 experts mainly from Nokia Siemens Networks and Nokia and co-edited by Nokia Siemens Networks’ Harri Holma and Antti Toskala. The 3rd edition of The IMS is a collaborative effort between Miikka Poikselkä, Nokia Siemens Networks and Georg Mayer, Nokia.

LTE for UMTS covers 3GPP Release 8 LTE standard for FDD (Frequency Division Duplex) and TDD (Time Division Duplex Modes) including physical layer, protocols, system architecture evolution (SAE), voice solution, radio resource management algorithms and the expected level of performance. Hailed as the telecommunication technology of the future, LTE is engineered for easy co-existence with GSM and WCDMA networks and for easy design of multiradio terminals and network products.

“As an organization, Nokia Siemens Networks has always believed in and encouraged knowledge-sharing to foster a global eco-system that benefits our customers, our organization and the society at large. LTE for UTMS is a reflection of this spirit. Together with Nokia we have been the most active contributors in many areas of 3GPP radio standardization. The book captures this end-to-end radio competence and shares best practices for the whole industry to read”, says Harri Holma, NSN fellow and co-editor of LTE for UMTS.

The 3rd edition of The IMS, consists of updated information on Third Generation Partnership Project (3GPP) Release 7 level, including architecture, reference points and concepts and substantially extended coverage on IMS detailed procedures. Additional new material in the 3rd edition of The IMS, includes completely rewritten IMS service chapter and new chapters on IMS multimedia telephony and IMS voice call continuity. Moreover, it describes new concepts such as, IMS transit, IMS local numbering, emergency sessions, identification of communication services in IMS, new authentication model for fixed access, NAT traversal and identification of user’s device.

Miikka Poikselkä, co-author of The IMS says, “The IMS has been immensely popular in the industry and has become a reference guide on IMS technology. With the technology itself being updated continuously, it was important for us to introduce a revised version. Georg Mayer from Nokia and I have tried to build on the achievements of the first two editions to provide a comprehensive coverage of IMS. It continues to explore the concepts, architecture, protocols and functionalities of IMS while providing a wealth of new and updated information,” he adds.
