A subscriber unit for use in a multiple access spread-spectrum communication system includes a spread spectrum radio interface, responsive to a rate function signal from a base station, and first and second despreaders. The base station assigns the rate function spread-spectrum message channels and the first despreader recovers and modifies an information signal one of the spread spectrum message channels. The information channel mode is then modified for processing by the second despreader, with the second despreader supporting a different information signal rate. The subscriber unit has a capability of communicating with a dynamically changing a transmission rate of an information signal which includes multiple spread spectrum message channels. The system includes a closed loop power control system for maintaining a minimum system transmit power level for a radio carrier station and the subscriber units, and system capacity management for maintaining a maximum number of active subscriber units for improved system performance.

1. A wireless subscriber unit comprising: circuitry configured to store a program received by the wireless subscriber unit in a first memory and for determining whether the program was received correctly; wherein the program is received via a wireless communications link;circuitry configured to store the program in a second memory, in response to a determination that the program was received correctly; andcircuitry configured to reboot the wireless subscriber unit and load the program from the second memory. 2. The wireless subscriber unit of claim 1 wherein the program is received by a modem of the subscriber unit. 3. The wireless subscriber unit of claim 2 wherein the modem is a CDMA modem. 4. The wireless subscriber unit of claim 1 wherein the program is received from an external device. 5. The wireless subscriber unit of claim 1 wherein the circuitry configured to reprogram the second memory uses the program stored in the first memory. 6. The wireless subscriber unit of claim 1 wherein the first memory is a FLASH memory. 7. The wireless subscriber unit of claim 1 wherein the controller receives current values of system parameters. 8. The wireless subscriber unit of claim 7 wherein the current values are provided by a modem. 9. The wireless subscriber unit of claim 7 wherein the current values are system noise interference levels, number of established calls, forward power control parameters, reverse power control parameters, time to access a channel, time to establish a channel or a number of dropped calls. 10. A method implemented in a wireless subscriber unit, the method comprising: storing a program received by the wireless subscriber unit in a first memory of the subscriber unit; wherein the program is received via a wireless communications link;determining whether the program was received correctly; andin response to a determination that the program was received correctly, storing the program in a second memory of the wireless subscriber unit and rebooting the wireless subscriber unit and loading the program from the second memory. 11. The method of claim 10 wherein the program is received by a modem of the wireless subscriber unit. 12. The method of claim 11 wherein the modem is a CDMA modem. 13. The method of claim 10 wherein the program is received from an external device. 14. The method of claim 10 comprising reprogramming the second memory using the program stored in the first memory. 15. The method of claim 10 wherein the first memory is a FLASH memory. 16. The method of claim 10 comprising receiving current values of system parameters by the wireless subscriber unit. 17. The method of claim 16 wherein the current values are provided by modem. 18. The method of claim 16 wherein the current values are system noise interference levels, number of established calls, forward power control parameters, reverse power control parameters, time to access a channel, time to establish a channel or a number of dropped calls.
