        5G-Core System Split Bearer's FILTER for Dual Access
          draft-sfc-sinha-5g-bearer-filter-dual-access-00

Abstract

   This document attempts the case for new work that need to be 
   developed for 5G user to improve faster download and upload of user's
   data via FILTER mechanism to be implemented at UPF user plane data
   for dual-access outlining the poor radio coverage issue. FILTER
   template governs the user data split at UPF with maintaining agreed
   PCC rules to achieve required throughput.

1. Introduction

   5G system have been evolved to server user in more efficient way of
   meeting higher download and upload of user data, whereas 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 a challenging for poor radio coverage (for both
   wi-fi and RAN). Hence re-engineering proposal has made in this
   document of 5G-Core entity UPF which is connected to Data Network
   handling user plane.

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 [RFC2119].

3. User data flow for Dual Access and problem statement

3.1 5G System architecture

   A simplified architectural diagram of 5G-system catering to both 
   access type 3GPP and Wi-Fi being supported by UE is shown in Figure 1
