                5G System Split Bearer for Dual-Access 
              draft-sfc-sinha-5g-split-bearer-dual-access-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
   user's data in a scenario of dual-access outlining the poor radio
   coverage issues. This document also outlines the faster user data
   mechanisum accompanying dual access capabilities of 5G user device 
   via split bearer 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, 5G Users accessing
   the network via wireline and wireless, in addition to this
   Residential Gateway RG and IoT support is also defined. Access and 
   user experience is challenging for poor radio coverage (for both 
   wi-fi and RAN) and the proposal in this document addresses the
   problem of poor coverage on either 3GPP or non-3GPP access with UE in
   dual-access mode.

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 [RFC2119].

3. User data flow for Dual Connectivity for Dual 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).

   User data of 5G system is delivered to user from Service or data
   network via interface N6 and N3 to UE.
