Work in progress
5G Fixed-Mobile Convergence
The 5G Fixed-Mobile Convergence work investigates important issues that impact design, implementation, deployment and operations of 5G in the broadband ecosystem. These issues closely relate to significant business opportunites. The work is being done in collaboration with other industry bodies such as 3GPP. Your participation is strongly encouraged.
The 5G Transport work addresses the requirements and anticipated migration of the 5G transport network to accommodate the anticipated new demands generated by the introduction of 5G globally.
Deployment
- Coexistence strategy: enables stress-free, market-paced migration from installed to new services
- Interworking: home access to 5G Core components
- 5G Fixed Mobile Convergence
The purpose of this work is to investigate common interfaces for the Access Network and Core Network, to support converged wireline-wireless networks that use the 5G core network. It studies the N1, N2 and N3 interfaces in order to provide detailed feedback to 3GPP in the context of 5G Fixed networks (as recommended by the joint 3GPP-BBF 2017 Workshop) and to facilitate 3GPP work in this area 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 operator requirements for interworking of existing fixed access subscribers and deployed equipment into a 5G core.
The study includes the examination of the following
- Registration and Connection Management Procedures
- Transport and Encapsulation in the Wireline Access of Control Plane (eg. NAS) and User Plane Traffic Exchanged with 5G Core
- Regulatory Requirements
- Operational Requirements
- Resource Management in the Access
- Session Management
- Addressing for IPv4 and IPv6
- Home LAN Support
- IPTV and Multicast
- Network Slice Selection
- QoS and Policy Management
5G Transport – The Foundation of the 5G Network
5G is slated to support masses of new devices, upgraded mobile phones and require extraordinary bandwidth and matching investment by operators and equipment manufacturers. The questions that the Forum are investigating include:
- Will the current transport network support the requirements of 5G?
- What routing & transport enhancements will be required for 5G covering capacity, performance reliability & determinism?
- What are the key recommendations should be made to the industry?
The forum’s work is based on more than a decade of related work as the industry has migrated from mobile generation to mobile generation. This page touches briefly on those highlights
5G Requirements
- Bandwidth, capacity
- Gigabit speeds vs. megabit speeds
- Performance
- Latency
- Loss
- Delay variation
- Reliability
- Availability and resistance to failure
- Isolation from interference
- Scalability
- Billion users and connected devices
