Breakout Session Abstract
Shipments for femto cells in 2011 outnumbered shipments of outdoor cell site radios in 3G and 4G/LTE networks. This is driven by the need to enhance coverage and increase capacity in the mobile networks. While the initial femto market has served needs of residential users, several other market segments have now emerged such as larger capacity pico cell and enterprise femtocells with service integration. This session will discuss 3G/4G small cells architecture and associated capabilities/challenges including interference management, zero-touch provisioning and Self Organising/Optimizing Network (SON), mobility and future architecture evolution for WiFi/Femto integration, enterprise support, etc. Cisco licensed small cells end-to-end solution will be described.

Ranges from ~$2/GB (3 carrier config) to ~$6/GB (1 carrier config)
Indoor offload solutions deliver very low incremental cost of production, similar to fixed Internet economics
As consumption rises, becomes more cost effective to offload traffic:
Compared with a 1-carrier macro cell, femto delivers improved economics for users with >750 MB/mo consumption
Compared with a 3-carrier macro cell, SP WiFi delivers improved economics for users with >500 MB/mo consumption

‒ X2 cluster/proxy function
‒ Traffic Offload

Assumptions
- No X2 mobility traffic (only S1 handover between Macro and Femto)
- SON related traffic only exchanged from macro to femto
- eNB derives TNL X2 cluster IP address from MME. Cluster eCGI points to the HeNBGW which answers the configuration messages

Cisco AT&T Deployment AT&T microcell officially launched in April 2010
http://www.wireless.att.com/learn/why/3gmicrocell/
Largest femtocell deployment ‒ Over 650k femtocell active
‒ 1.8 Millions of call per day with 7 Millions of minutes
True zero-touch provisioning ‒ Over 92% of femto installation done without customer care intervention
‒ Fully automated provisioning and management control (e.g. whitelist management)
BEST COMMERCIAL FEMTO LAUNCH AT&T’s 3G MicroCell National Deployment
“AT&T’s 3G MicroCell deployment with Cisco caught the judges’ eyes for two crucial reasons. First and foremost, it emphasised the importance of the customer at the heart of the femtocell experience, positioning technology very much as an enabler, rather than an end in itself. Secondly, the deployment is on a national scale, which given the US market’s size adds an additional layer of complexity”, agreed the judges.

Femtocell Interference Management
Femtocell coverage is typically specified in terms of the Common Pilot Channel (CPICH) signal strength and Ec/N0
‒ CPICH signal strength (i.e. RSCP) depends on building characteristics (size, floor-plan, construction materials, etc.)
‒ Femtocell CPICH Ec/N0 value depends on RSCP and interference from neighbouring Macro and/or Femto cells
Ideally, Femtocell coverage should be limited to indoors
‒ Optimal CPICH setting will have to be determined for each location.
‒ Outdoor RF leakage shall be minimized to limit coverage dead zones
Cell re-selection and handover parameter settings depend on femto deployment scenario

Self Organizing
All femto cells have a listen mode capability to measure the macro cell power and potentially other surrounding femtocells transmissions
‒ Macro cell reception (when available) is used to set femto Tx power, to identify network (MCC/MNC), to update list of neighbouring cells and for synchronisation
‒ Other Femtocell reception is used to select the best scrambling code (PSC) out of the reserved list of codes

Mobility Requirements
‒ Idle Mode reselection

‒ Hard Handover vs Soft Handover
Mobility Procedures Specified Over Several Releases

Hand-out (Femto to Macro) Supported(1) Supported Supported

Notes:
(1) Supported based on existing 3GPP procedures
(2) Several mechanisms defined for PSC disambiguation (e.g. IMSI filtering, time difference, etc.)
(3) Based on UE reporting actual cellId instead of PSC only; requires UE and UTRAN support
(4) Introducing a new Iurh protocol for inter-femto communication
© 2012 Cisco and/or its affiliates. All rights reserved. BRKSPM-2244 Cisco Public
Femto Access Control
Multiple access control modes
‒ Closed access: restricted to a set of identified users
‒ Open access: all users can access the femtocell (femto as an extension to macro)
‒ Hybrid access: privileged access to identified set of users and open to others with restrictions
Access control is invoked at UE registration with configurable reject methods
‒ Standard Location Update Reject (barring whole LAC)
‒ Option to use Authentication Failure (barring Cell only)
Two ways to identify the users:
‒ IMSI whitelist stored at HNBGW and optionally at HNB (pre-R8 UEs)
‒ Closed Subscriber group (R8+ UEs)
CSG Id is broadcasted by femto and used by the UE and the network during registration
CSG list distributed via OMA-DM to the UEs
‒ Potential convergence with ANDSF specified for WiFi selection

Backhaul Management
Minimising uplink backhaul bandwidth for multiple concurrent CS calls
‒ Uplink CS multiplexing combines simultaneous calls into shared RTP packets
‒ RTP header compression is also applied
Different signalling/traffic types can be DSCP-marked
‒ Allows prioritisation / rate capping if IP network is QOS-capable
Minimal overhead for supervision
‒ For idle AP carrying no user traffic (e.g. essential supervision data usage per month is approximately 19 MB for uplink or downlink for Cisco AP)
‒ Includes signaling heartbeats, IPsec NAT keep-alives, IKE Dead Peer detection
‒ Highly-optimised NTP solution for S class only adds 0.14 MB/month
‒ Full PM Counter file upload approx 20MB/month (hourly counts; daily upload)
