Handling errors occurring in base-station of a CDMA system

Method for controlling a CDMA base station comprising a transmit stage and a receive stage for communicating with mobile terminals, the transmit stage comprising a power amplifier having at least two independent power modules (10, 11) transmitting signals on at least one traffic channel 0 and control and pilot signals on at least one control channel (CCH), each power module (10, 11) being capable of being operational even though one other power module is non-operational, the at least two power modules normally being adapted for operating simultaneously and each contributing with emitting power, whereby the method comprises the following steps,

• continuously monitoring the fault status of individual power modules in a base station,
• if a fault in a power module is detected, turning off the faulty power module (10, 11),
• stopping traffic channels (TCH) in sector/cell associated with faulty power module (10, 11),
• increase power on control channel (CCH) to nominal level
• disable TPC power loop,
• delete traffic for predetermined group of terminals,
• enable TPC power loop,
• set up communication with remaining terminals in sector,
• allocate traffic channels (TCH) in sector/cell to remaining terminals at new reduced power level (Prmaxf).
