An Introduction to LTE: LTE, LTE-Advanced, SAE, VoLTE and 4G Mobile Communications
Following on from the successful first edition (March 2012), this book gives a clear explanation of what LTE does and how it works. The content is expressed at a systems level, offering less technically experienced readers the opportunity to grasp the key factors which make LTE the hot topic amongst vendors and operators across the globe. Assuming no more than a basic knowledge of mobile telecommunication systems, the reader is not expected to already understand complex mathematical operations. This second edition both updates and introduces new material for the current state of the industry, such as:- VoLTE, and how to handle voice calls at the outset; how the LTE market has been evolving; an enhanced section on home eNBs (the hardware that is connected to the mobile phone network that communicates directly with mobile handsets) and the transport network; how the radio spectrum is actually being used by network operators worldwide; how uplink transmissions are actually triggered; improved descriptions of policy & charging control and data transport; connection to a second packet data network, a procedure that is used by the IP multimedia subsystem; routing updates and RRC connection release with redirection, procedures that are used by circuit switched fallback; heterogeneous networks and data transport enhancements. The author breaks down the system into logical blocks, initially introducing the architecture of LTE, before explaining techniques used for radio transmission and reception and the overall operation of the system. This methodical approach enables readers to move on to tackle the specifications and the more advanced texts with confidence.
