       5G-System Bearer Offloading for Dual Connectivity for RAN
                draft-sfc-sinha-5g-bearer-dc-ran-00

Abstract

   This document attempts the case for new work that needs to be 
   developed for 5G users to improve faster download and upload of the
   user's data in a scenario of dual-connectivity 3GPP access outlining
   the poor radio coverage issues. This document also outlines the
   faster user data mechanism accompanying 3GPP access of 5G user
   device via bearer offloading in case of a poor coverage.

1. Introduction

   5G system has been evolved to serve the user in more efficient way
   of meeting higher download and upload of user data for 5G Users
   accessing the network via wireline and wireless, in addition to
   Residential Gateway RG and IoT support. In 5G system Access and
   user experience is challenging for poor radio coverage (for both
   wi-fi and RAN) and the proposal in this document addresses to the
   problem of dual-connectivity of 3GPP access with Master-gNB having
   poor coverage.

2.  Conventions and Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [1].

3. User data flow for Dual Connectivity for 3GPP access and problem 
   statement

3.1 5G system architecture
   
   A simplified 5G-system architecture shown in Figure-1 in the case of 
   UE in non-roaming scenario with RAN access(3GPP).
