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


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.

Packet Core Evolution


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.


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)


ASR 5000 Multimedia Core Platform Deployment flexibility

Non bladed architecture enables flexible and efficient usage of resources

Same platform for all functional elements (today's and tomorrows)

• GGSN, SGSN, PDSN,S-GW, P-GW, MME

Simplification• Any combination of 2G / 3G / EPC functions can be co-located on an ASR5k platform

• Enables maximum flexibility for resource allocation

Interface continuity from UMTS to EPC• OAM, Charging, PCC, AAA, ...

Same services • QoS control, DPI, LI, content charging, security, filtering, ...

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
