Abstract
A code division multiple access (CDMA) user device includes a CDMA transceiver, and a controller connected to the CDMA transceiver for establishing a communication session with a base station. The communication session includes a plurality of layers including a physical layer. The controller negotiates with the base station for an allocated bandwidth for the CDMA transceiver. The controller also establishes and releases a physical layer connection between the CDMA transceiver and the base station, and maintains a state of at least one other layer during the communication session after termination of the physical layer.
