Title: Traffic Management for Mobile Broadband
Abstract:
Mobile broadband enables advanced data services, and data traffic;
the number of mobile data subscriptions is increasing rapidly along
with a continuous increase in the average data volume per
subscription, driving growth in data traffic. Cellular systems by
nature have finite resources, and shared between many users and
services. Mobile broadband networks must support multiple
applications of voice, video, and data on a single IP-based
infrastructure. These converged services each have unique
traffic-handling and QoE (Quality of Experience) requirements.
Traffic management is the term used to describe a range of technical
practices undertaken to manage traffic across networks. The
different outcomes achieved by the use of technical practices can
include:
• The prioritization of certain types of traffic
• The slowing down of certain traffic types
• Supporting the delivery of managed services
Traffic management for mobile broadband networks requires visibility
to what is occurring (by device or application) at the cell site
level and in a timeframe that enables as far as feasible near-time
reactions to resolve issues. In many cases, traffic management
practices serve as an effective mean to provide quality services to
end users. Mobile operators can take two major approaches to
significantly reduce the risk of cost outstripping data revenues:
- Network Optimization
- Network Sharing
