ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to digital cellular systems and, more particularly, to a method for controlling the transmitting power in a base station transceiver subsystem.
2. Description of the Related Art
In a digital cellular system such as a CDMA (Code Division Multiple Access) system or a PCS (Personal Communication System), when a call processing service cannot be provided or such service is partially limited due to abnormal circumstances present in a base station transceiver subsystem, the normal transmission of a transmitting power results in interference with other normal systems. In such a circumstance, service quality as a whole is reduced.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a control method for blocking the normal transmitting power when a call processing service cannot be provided or such service is partially limited due to abnormal circumstances present in a base station transceiver subsystem
It is another object of the present invention to provide a method for controlling the transmitting power in accordance with present operating conditions in a base station transceiver subsystem.
According to one feature of the present invention, a method for controlling the transmitting power in a base station transceiver subsystem includes the steps of collecting and combining fault information from devices that provide factors affecting a call processing service, and determining the range of transceivers that should have blocked transmitting power based on the collected and combined fault information. The transmitting power of the determined range of transceivers is blocked by sending a message to a corresponding transceiver interface processor connected to each of a plurality of transceiver groups within the base station transceiver subsystem. The transmitting powers are normally transmitting by sending a message to the corresponding transceiver interface processor, when a fault ceases.
