       5G System Split Bearer in Dual Connectivity of WiFi
                draft-sfc-sinha-5g-bearer-dc-wifi-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-connectivity for non-3GPP access
   outlinig the poor wifi coverage issues. This document also outlines
   the faster user data mechanism accompanying non-3GPP access of 5G
   user device via split bearer in case of a poor coverage.

1. Introduction

   5G System has been evolved to serve 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 Residential 
   Gateway RG and IoT support.In 5G System, access and user experience
   are a challenging for poor radio coverage for both wi-fi and RAN. 
   The proposal in this document address to the problem of non-3GPP
   access only when 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 non-3GPP Access and problem
   statement

3.1 5G System Architecture

   5G System supporting UE access to the network function and services
   via non-3GPP is shown in Figure-1. An example of such access is
