LTE impact on Telco architecture

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.
