Abstract
The mobile station includes a system for using open channel time not needed during access to the wireless web. The mobile station monitors the use of the channel, and determines when the user is no longer transmitting or receiving information. Until the current network session terminates, the mobile station may operate in the background to either send or receive information with the network. Any action taken by the user would take priority over the background operations.

A method of utilizing a network connection in a wireless communication system comprising:
- establishing the network connection for one or more billing intervals;
- receiving initial information corresponding to requested network activities:
- determining that all the requested network activities are completed;
- detecting an amount of time that the network connection will remain active in the current billing interval;
- and
- automatically communicating along the network connection for receiving updated information not corresponding to the requested network activities when the amount of time that the network will remain active is greater than a specified amount.

A mobile station comprising:
- a network interface which communicates with an external network;
- an interval timer which calculates the amount of time remaining in a billing interval;
- a processor which completes one or more requests along the network interface and receives information corresponding to the one or more requests;
- wherein:
- the processor receives the initial information corresponding to the one or more requests and initiates automatic communication along the network interface after receiving the initial information to receive updated information not corresponding to the one or more requests, the updated information being in the same category as the initial information;
- the mobile station further comprising:
- memory which stores the updated information transmitted along the network interface prior to expiration of the interval timer.
