Abstract
A method and apparatus, such as a pico service gateway, for reducing backhaul traffic in a broadband wireless access system are provided. The pico service gateway operatively receives an uplink packet including a contents request from a Mobile Station (MS). Upon receipt of the contents request, the pico service gateway determines whether the requested contents have been cached. If the pico service gateway determines that the contents have not been cached therein, the pico service gateway communicates with a corresponding server to receive the requested contents. Thereafter, the pico service gateway transmits the contents to the MS. Further, if the pico service gateway determines that the contents have not been cached, the pico service gateway caches the contents. In contrast, if the pico service gateway determines that the contents are cached therein, the pico service gateway transmits the contents corresponding to the requested contents.
