Index 391 Foreword When we designed the first generation of digital mobile networks, the concept of a self-organising network (SON) was not in focus Now, with hindsight we can say that a lot of self-organising features already exist such as power control, handover between cells and efficient customer management based on central administration of SIM cards Why has the vision of self-organising networks. .. Networks (SON) concept is considered to be an integral part of LTE Introduction 3 1.1 Self-Organising Networks (SON) The concept of SON became frequently used after it was adopted by the Next Generation Mobile Networks (NGMN) alliance to address challenges foreseen due to management of several radio access technologies along with the LTE network introduction Chapter 3 provides an introduction to the... introduced network scenarios relevant for SON A particular scenario is a ‘Heterogeneous Networks scenario in which a network is made of several different cell types, technologies or layers Such a network will impose stronger requirements for SON with regards to scalability, interoperability but also improved functionality Therefore a separate chapter, Chapter 10, is dedicated to SON for heterogeneous networks. .. functionality that is relevant for operators Deutsche Telekom together with their partner in the NGMN Alliance (Next Generation Mobile Networks) have taken the initiative to drive Self-Organising Networks (SON) Within the vision of SON the operators have defined the most relevant use cases for the automation of operational tasks: typically, those tasks that require significant manual effort, or tasks that are... 12 LTE Self-Organising Networks (SON) References Heylighen, F (2009) Self-Organisation, Principia Cybernetica Web http://pespmc1.vub.ac.be/selforg.html [accessed 30 June 2011] Holma, H and Toskala, A (eds) (2011) LTE for UMTS: Evolution to LTE- Advanced, Revised Edition, John Wiley & Sons, Chichester, Chapter on SON Laiho, J., Wacker, A and Novosad, T (2006) Radio Network Planning and Optimisation for . alt="" LTE SELF-ORGANISING NETWORKS (SON) NETWORK MANAGEMENT AUTOMATION FOR OPERATIONAL EFFICIEN CY Edited By Seppo Ha ¨ ma ¨ la ¨ inen, Henning Sanneck, Cinzia Sartori Nokia Siemens Networks This. be sought.
