       LPWAN Static Context Header Compression (SCHC) over NB-IoT
                    draft-minaburo-lpwan-nbiot-hc-00

Abstract

   The Static Context Header Compression (SCHC) specification describes
   a header compression and fragmentation functionalities for LPWAN (Low
   Power Wide Area Networks) technologies.  SCHC was designed to be
   adapted over any of the LPWAN technologies.

   This document describes the use of SCHC over the NB-IoT channels, and
   provides elements for an efficient parameterization.

1.  Introduction

   The Static Context Header Compression (SCHC)
   [I-D.ietf-lpwan-ipv6-static-context-hc] defines a header compression
   scheme and fragmentation functionality, both specially tailored for
   Low Power Wide Area Networks (LPWAN) networks defined in
   [I-D.ietf-lpwan-overview].

   Header compression is needed to efficiently bring Internet
   connectivity to the node within an NB-IoT network.  SCHC uses an
   static context to performs header compression with specific
   parameters that need to be adapted into the NB-IoT channels.

   This document describes the use of SCHC and its parametrizing over
   the NB-IoT channels.
