Alleviating Network Tower Congestion by Leveraging GPS -Enabled Devices

Large amounts of mobile data are streamed as a vehicle travels and transitions from tower to tower. Cellular phone network towers become congested in areas of high cell phone usage, and traffic conditions can contribute to unexpected congestion on a single tower. Despite the network being aware of congestion, mobile devices will continue to transition to congested towers and request the same content that was previously available from an uncongested tower, resulting in dropped calls, poor quality of service, etc.

Currently, most methods of alleviating and dealing with this congestion are reactive; algorithms and hardware are used to mitigate existing network strain on a single tower. [1, 2, 3]

Disclosed is a method of alleviating traffic on cellular towers by pre-fetching content prior to switching to the congested tower.

In the preferred embodiment, cellular network towers broadcast their congestion levels, and global positioning service (GPS)-enabled devices anticipate when they will switch to a congested tower based on the projected route. The device notifies its applications of upcoming congestion, enabling them to prepare themselves accordingly (e.g. pre-fetching content) to reduce strain on the congested tower.

In an alternate embodiment, trip and route information can be sent to the service provider, and the provider will reply to indicate that the device will soon enter an area of high network congestion.
