Description
This book addresses the needs of managers, engineers and technicians who are involved in the design, consideration and development of interworking implementations between LTE and other 3GPP cellular standards on one hand and WiFi on the other hand. In that respect, the book focuses on both sides, UE/Mobile as well as network.
The book starts with an overview of the Mobile Network Architecture with Protocol Stacks, Access capabilities and applicability as well as handover principles.
We will then review different interworking options, such as I-WLAN, WISPr, tunneling through GAN / UMAN / VoLGA or as non-trusted, non 3GPP access network connecting to LTE infrastructure with DSMIP or PMIP as well as reviewing voice call setups with and without IMS support.
The book will continue with a detailed review of the 802.11 variants, differences and internal functions. This part provides a roadmap from 802.11-1999 up to the most recent 802.11n version.
We will discuss WiFi access mechanisms to the physical transport, such as CSMA/CD and the function and purpose of the DCF access function. This is done as it is crucial to understand the specifics and differences of WiFi vs. cellular network operation.
The interworking with the Physical Protocol Layer will be discussed both from the perspective of the terminal and from the network side with constraints, access permission mechanisms, how to obtain IP addresses etc.
The book will conclude with a comparison of the different access architectures, related handover types and recommendations regarding a most suitable implementation.
