Abstract
A method for operating a CDMA user device includes establishing a communication session with a base station. The communication session includes a plurality of layers including a physical layer. A service configuration is negotiated with the base station, and the user device receives an assigned subchannel from the base station. A physical layer connection is established with the base station on the assigned subchannel. The physical layer connection corresponds to the physical layer. The method further includes releasing the assigned subchannel so that the physical layer connection is terminated, and maintaining a state of at least one other layer during the communication session after termination of the physical layer.
