Mission Statement:

This Work Area addresses the increasing synergy between wireless access technologies and wired access technologies, as well as that of wireless networking and wireline networking functions. Activities examine scenarios where wireless access technologies play a role or mobile networking is involved in the wireline network. 

Work Area Director: David Allan, Ericsson

Business Impact:

The principle impact on the market addresses the ability to create seamless connectivity to either wireline or wireless access connectivity from single or multi-tenant business and residential locations that will radically alter users' network experience. This is the next step in the evolution from the automatic connectivity to available Wi-Fi networks and will become the norm with the advent of 5G.

Scope:

Topics in this area within scope are Wi-Fi as last mile for broadband access, small cells, hybrid (dual access) access, functions between wired and wireless networks that may be instantiated as a common element, wireline and wireless network interworking and convergence at the service and subscriber level. The virtualization aspect of identified common functions will enable future study in the area of VNFs and NFVI destined for mobile and fixed networks and next phase of FMC evolution.

5G Requirements and Enablers

SD-373 investigates the potential of 5G in the BBF providing a gap analysis and recommendations for further technical studies. It elaborates 5G use cases considering other standardization bodies including NGMN, 3GPP, ITU and 5GPPP and analyzes the 5G technical enablers focusing on (i) unified control plain (FMC), (ii) function (de)composition and allocation (NFV), (iii) network slicing considering SDN and NFV aspects (iv) transport networks focusing on backhaul and fronthaul and (v) edge computing.

SD-406

End-to-End Network Slicing

The purpose of this study is to investigate the concept of network slicing with respect to the BBF MSBN architecture. Network slicing is considered as a fundamental enabler the BBF MSBN needs to support in order to move from the paradigm of “one architecture fits all” to the logical “network per service”. Network slicing will enable value creation for vertical segments that lack physical network infrastructure, by offering network and cloud resources.

5G Fixed Mobile Convergence

The purpose of this study is to find common interfaces for the AN and CN, to support converged wireline-wireless networks that use the 5G CN. 

This project will study N1, N2 and N3 interfaces and provide detailed feedback to 3GPP in the context of 5G Fixed (as recommended by the joint 3GPP-BBF Workshop), to let 3GPP evaluate how to proceed with this as swiftly as possible. 

This project will specify of a 5G Access Gateway Function (AGF) that adapts fixed access onto the 5G core, and then consider and specify several architectural deployment options as well as the underlying infrastructure sharing aspects. 

It will also devise strategies and develop specifications to address a desire by a number of operators for interworking of existing fixed access subscribers and deployed equipment into a 5G core.

With the outcome of this project, BBF will provide recommendations for 5G system architectural and functional integration related to highlighted/identified convergence items during the joint 3GPP-BBF Workshop.

Combined 3GPP and BBF Functions

This document contains the results of the study on 3GPP-BBF Common Functions, that is performed in a stepwise approach, addressing the following business needs:

1 – Identification of common network functions between the 3GPP and BBF domains is a necessity

2 –Analysis of virtualization aspects of identified common functions, as an enabler for future study in the area of

Virtualized Network Functions (VNFs) and Network Function Virtualization Infrastructures (NFVI), destined for mobile and fixed networks.

The results of this work in the BBF serve as a foundation for further collaboration opportunities with the 3GPP and with the ETSI ISG NFV.
