Abstract
A method is provided which permits the conservation of wireless mobile station battery power in a system where only the mobile station initializes requests for data transfer, such as a wireless packet switched connection network. The method is especially practical in the transfer of large amounts of data that need not be received in real-time. Since only the mobile unit user, or mobile unit imbedded applications program initiates requests for data transfer, the mobile station need not monitor the forward link signal. The mobile station Deep Dormant™ mode saves battery power by completely disabling the receiver circuit when no data is to be sent or received. As a result, the mobile station enjoys longer battery life.
