Abstract

Examples of the invention allow a content service provider to utilize one or more overlapping wireless networks in a given area to efficiently and cost effectively deliver content and services to a mobile device contained within a terminal. Examples of the invention analyze the characteristics of each wireless network such as cost, latency, security, and bandwidth, the terminal capabilities, and the requested service to determine the most efficient manner to deliver services over one or more wireless networks in a given area. In addition, the service provider re-analyzes the efficiency of service delivery when the mobile device enters a new mobile area. Therefore, sustaining efficient content and service download throughout delivery.
