A base station includes a wireless transceiver for establishing a communication session over a first digital communication path, and a bandwidth management module is connected to the wireless transceiver for allocating at least one code channel within the at least one radio frequency channel for exchanging digital signals over the first digital communication path during the communication session. The at least one code channel may include at least one traffic portion that is established for a predetermined time and at least one control portion that is continuously available. The bandwidth management module may reallocate the at least one traffic portion from the first digital communication path to a second digital communication path if an extension of time is not requested from the base station over the first digital communication path for the at least one traffic portion, or if the base station no longer has digital signals to transmit over the first digital communication path via the at least one traffic portion. However, the at least one reallocated traffic portion appears as though it is still continuously available to the first digital communication path.
