  • Draft: Speaker Line-up Carsten (webinar host): (10 minutes) Welcome & speaker intro MEF intro and Analyst view Peter: MEF 22 Phase 1 IA (10 min) Rami: Legacy Migration - Use case explained (10 minutes) Karim: Legacy Migration - CoS & Sync delivery (5 min) Jonathan: MEF 22 Phase 2 - Ethernet for LTE (10 min) Carsten: (1-2 min) Prepared Q&A discussion with all speakers Questions from participants (if time permits) Conclusion & open invite to contact MBH team
  • MEF Introduction Carrier Ethernet for Mobile Backhaul MEF Specifications and Mobile Backhaul MEF 22 – Mobile Backhaul Implementation Agreement Legacy Mobile Backhaul Migration – Case Study Preparing Ethernet Services for LTE – MEF 22 Phase 2
  • Phenomenal growth in mobile subscribers during Y2009 Significant increase in packet-data services in mobile network The trend is heading 50Mbps capacity per cell site for Y2010 Packet Switched Network promises more bandwidth at lower costs Traditional wireline TDM expansion can’t meet traffic growth and expenses Leased-line OPEX (globally) for mobile operators estimated at $22B Standardization process 3GPP ( 3rd Generation Partnership Project) ITU-T / ITU-R (Telecommunications / Radio) IEEE 802.16 / WiMAX forum Carrier Ethernet MEF 22 (MBH IA) MPLS & Broadband forum (Framework & requirements) IOMETRIX – MEF and CES services certification EANTC – Mobile backhaul interoperability events
  • Suggest that we show the TC dashboard here, perhaps faded out, with an pop-out point to some key MEF specs such as 6.1/10.1 etc. that should be of interest to operators We can build the story in speaking notes
  • The Mobile Backhaul is defined as the network between the: Radio Network Controllers (RNCs), and Radio Access Networks Base Station (RAN BS). MEF22 provides guidelines to architecture, equipment & operation to that part of the network MEF22 Explains how to apply existing MEF specifications to Mobile Backhaul Provides generic specification for Ethernet backhaul architectures for mobile networks (2G, 3G, 4G) User-Network Interface requirements Service Requirements Clock synchronization Common Terminology Offers a standardized toolset
  • The RAN CE is a generic term that identifies a mobile network node or site, such as a RAN network Controller or RAN Base Station A RAN NC may be a single network controller or a site composed of several network elements including: OSS, WCDMA Radio Network Controller or Synchronization Server.
  • Bandwidth Requirements Base station BW requirements vary from site to site Range from few Mbps to more than Gbps Support hundreds to thousands of RAN BS sites per RNC site MEF Services Generally, the requirement is to follow one of the following MEF services: Ethernet Private Line Service Ethernet Virtual Private Line Service Ethernet Private LAN Service Ethernet Virtual Private LAN service Ethernet Private Tree Service Ethernet Virtual Private Tree Service
  • Mobile Operator A has operates 2G and 3G mobile networks that utilizes TDM leased lines 3G base stations have both TDM-based and Ethernet interfaces and support IP Both systems are FDD (frequency sync) Mixed configuration sites Mobile broadband traffic generates more volume than can be supported cost-efficiently by legacy network Decision: Mobile Operator A wants all 2G and 3G transport to utilize Carrier Ethernet services How to transport 2G non-Ethernet interfaces? How to define services? How to deliver synchronization? How to monitor services?
  • The GIWF provides adaptation and interconnection between any legacy mobile equipments (TDM/ATM/HDLC based) at the BS/NC and the Carrier Ethernet network at the UNI. It enables the joint backhaul of any combination of 2G, 2.5G, 3G (legacy based) and Evolved-3G & 4G (Ethernet based) voice and data traffic over a single Carrier Ethernet RAN. The GIWF implementation could be based on TDM circuit emulation standards as well as ATM/HDLC pseudo-wire standards.
  • Guidelines for the number of CoS classes to use Bundling traffic types into limited number of CoS classes CoS class performance requirements
  • This is background with regard to phase I Packet Based Synchronization Challenges: No end-to-end physical layer clock synchronization Packet delay variation – caused by queuing delays, routing changes, network technology Packet loss Symmetric/asymmetric network MEF22 Approach to Synchronization Packet based methods are in scope for Phase 1 Synchronization quality requirements reference the ITU G.8261standard The IA is agnostic to specific methods/implementations like Adaptive Clock Recovery (ACR), Extended ACR (RTP Header), IEEE1588v2, NTPv4, etc. Synchronous Ethernet - in scope for phase 2 Non Ethernet sync (GPS, legacy E1 clocking) is outside of the IA scope
  • Ethernet OAM Provides Ethernet with management features similar to legacy services Features Connectivity Fault Management Performance Management Link Management Deployment Ethernet can start at the Base Station or the legacy traffic can be “converged” onto a Carrier Ethernet Network The following slide provides a picture of where Ethernet OAM is performed from the Wireless Providers perspective and from the Backhaul Operators perspective
  • LTE Understand LTE and what requirements it puts on Ethernet services Synchronization Take a deep dive into frequency synchronization requirements and available timing methods Resiliency Look at resiliency and how it applies to MBH Ethernet services Performance monitoring Examine what needs to be monitored and establishing a reference model applicable to MBH Service performance recommendations Proposing common MBH Ethernet service performance recommendations
  • Focus is on achieving frequency synchronization Synchronous Ethernet Output requirements specified based on ITU-T recommendations New UNI attribute to specify availability of SyncE Packet based methods Continue to align with ITU-T recommendations
