Content Filtering
Content Filtering is an in-line service available for 3GPP and 3GPP2 networks to filter HTTP and WAP requests from mobile subscribers based on the URLs. Network service applied to subscriber sessions
Content categorized into classes
Subscribers classified in terms of permissible network content
Data traffic to the mobile handset is filtered
Action taken based upon subscriber –x- data classpermit, block, redirect, alter content
Applied optimally at network edge before unnecessary traffic enters network
Subscriber awareness required
May be done on or off board the ASR5K

Traffic Performance Optimization (TPO)Client-less optimizations:
Better Mobile Data User experience
Faster response time
Higher throughput
Better wireless bandwidth utilization
Less bandwidth used
Able to consume closer to theoretical bandwidth limit
Several types of traffic
TCP; improvements are primarily effective during peak hours
HTTP; improvements are in addition to TCP improvements
Video; improvements are in addition to TCP, whenever TCP is used
Client-full optimizations: under investigation
© 2009 Cisco Systems, Inc. All rights reserved. Cisco ConfidentialPresentation_ID 33
TPO Benefit Targets
TCP Optimizations• +30% downlink throughput during congestion periods
• Allows closer to theoretical bandwidth utilization by reducing limitations of standard TCP handshaking
• Adapt to wireless network events and conditions, optimizing data transmission rate for available bandwidth and round trip time
• Minimize TCP retransmissions
HTTP Optimizations• Payload reduction of 50% for text-based pages (70% compression of text,
but packet headers are not compressed), albeit such pages do not account for much traffic and servers themselves could do the compression
• Minimize # of round trips from clients, enabling faster response time
Video Optimizations• Remove unnecessary video detail to save bandwidth
• Improve user experience by controlling what is dropped during congestion periods
• Text insertion and/or picture-in-picture as a new revenue source.

Why LTE/SAE? Some LTE/SAE Facts
Faster Network/ Better Spectrum efficiency
• Up to 300Mbps DL & 75Mbps UL, MIMO• Up to 500 kph mobility support, but optimized for 0-15kph• < 100ms control plane latency• < 5ms user plan latency
Flat network architecture for LTE RAN (E-UTRAN)
• Significant amount of micro mobility and IP layer tunnel switching among MME, SGW and eNB
• Simplified RAN, no RNC• Simpler eNodeB
All IP Packet Services Network
• Data + Voice Solutions +Multimedia
QoS and IMS readiness is built in for LTE rather than add on
Enhanced Packet Core (EPC) for 3GPP and non-3GPP accesses
• A single IP core with PDN-GW as the IP anchor.
© 2009 Cisco Systems, Inc. All rights reserved. Cisco ConfidentialPresentation_ID 45
LTE / EPC Challenges 1. Network Optimization
• How to re-use of current UMTS PS core solution• Avoid parallel networks for EPC and UMTS PS• Flexible evolution and coexistance of 2G / 3G to LTE
2. Voice grade reliability• No dedicated CS bearers, voice must be carried over packet
3. Throughput• DSL like throughput• 100s of Gbps for nationwide deployments
4. Signaling Increase• TAUs, paging (network initiated bearer activations)• EPC signaling load is an order of magnitude higher than 3G
PS Core signaling load
5. Intelligence at the Core (Policy Control)

Packet Core Evolution How UMTS transitions to LTE
RNC functionality is split between SGSN control plane and NodeB which becomes eNodeB as radio resources, RoHC, ciphering are performed here
SGSN is split between Control and Bearer plane. Control part becomes MME, Bearer part becomes SGW
GGSN becomes PGW and is enhanced to accept multiple access technologies

Scalability = transaction rate + throughput + density + latency
Other platforms = maximize only one parameter
ASR 5000 = superior performance across all parameters
ASR5000’s distributed architecture combines superior performance across all parameters
Purpose built for the market
Throughput performance
35 Gbps with DPI
Signalling performance
Up to 560 k paging messages / sec (egress)
Up to 25 k intra-SGW HO
Density
MME = 4M/8M Sessions/Bearers
SGW = 4M/8M Sessions/Bearers
PGW = 4M/8M Sessions/Bearers
PSC (Packet Service Card)The only card needed for services and for expansion
