Long Term Evolution (LTE) 4G is an all-IP standard for high-speed wireless communication. Communication service providers need to evolve to LTE to stay competitive and pursue the next growth curve in broadband. Transitioning to LTE will impact a telco's enterprise systems like the BSS, OSS, and ESS through changes to the network architecture, business rules, billing models, and application landscape. Telcos should analyze the impact on their architecture, identify required system changes, engage vendors, and plan a phased rollout strategy to successfully adopt LTE.

Key risks & challenges Next steps
Current realities
 Communication Service Providers need to stay ahead of the
curve in 4G evolution
 The business is evolving towards the “internet of things”, mobile
commuting and data-hungry devices
Current risks
 Next growth curve is Broadband
 Revenue loss and market erosion by not evolving to LTE
 Market challenge from pure-play OTT players
Actions
 Analyse impact of LTE on a typical Telco Enterprise Architecture
 Plan for and get funding for changes in readiness
 Rollout (phased)
 Benefits realization
Business issues
 Broadband not robust enough to offer enhanced VAS (Value Added
Services)
 High OPEX/CAPEX in 3G
 Low user satisfaction in current 3G offerings

 Device management rules
 - to curb fraud take control of device
& subscriber authentication
 Prone to man in the middle attacks as IP
connection giives open internet access.
 Automated SIM & number management
 Improved turnaround time for SIM Ordering
from manufacturer .
Business Impact
 Network Core component change
 Separation of Services and Bearers e.g. SMS as a
service and as a traffic bearer.
 IPV6 Alignment
 Migration of applications from Network core to
mobile device
 Pressure on network capacity
 Investment in DPI technology
 Increase in technical connections and interfaces
 Protocol Standardization
Technology Impact
 Change in SIM configuration rules
 IPV6 Alignment
 Mediation Business Rules alignment
 Business rules on RA/FMS to link authentication
and subscriber details.
 Changes in interconnect to cater for changes in
billing record transfer
 Charging rules alignment to interface with IP
based networks
