A system, method, and program for optimizing the data channel availability on a computer device through selectively delaying the closing of an open channel on a computer network having expensive bandwidth, such as a cellular telecommunication network. The device has a plurality of device resources that utilize an open channel to communicate across the network, and optimally delays the closing of an open communication channel after cessation of usage thereof by a device resource such that other device resources can utilize the open communication channel prior to closure while still minimizing the duration of the expensive open channel.
