Abstract
An apparatus and method for measuring and reporting uplink load in a base station (BS) in a cellular mobile communication system are provided. The BS includes a rise over thermal (ROT) detector for measuring a ROT representing uplink load, and reporting information from which the ROT can be derived to a base station controller (BSC) via a standard interface. The ROT detector measures as background power the received power of the BS for a call-free period, the minimum of received power of the BS, or the minimum of received power of the BS measured for a predetermined time period. Then the ROT can be obtained by subtracting the background power from the received power of the BS.
Claims35
An apparatus for measuring and reporting uplink load in a base station in a cellular mobile communication system, comprising:
- a measurement controller for detecting a period for which no call is placed in the base station, or in the base station and adjacent base stations;
- a background power measurer for receiving total received power of the base station and outputting the minimum value of the total received power for the detected period as background power;
- and
- a subtractor for generating a rise over thermal (ROT) value representing the uplink load by subtracting the background power from the total received power of the base station for a non-detected period.
An apparatus for measuring and reporting uplink load in a base station in a cellular mobile communication system, comprising:
- a measurement controller for determining a measuring period for background power;
- a background power measurer for receiving total received power of the base station and outputting the minimum value of the total received power for the determined measuring period as background power;
- and
- a subtractor for generating a rise over thermal (ROT) value representing the uplink load by subtracting the background power from the total received power of the base station for a non-measuring period.
An apparatus for measuring and reporting uplink load in a base station in a cellular mobile communication system, comprising:
- a background power measurer for receiving total received power of the base station and outputting the minimum value of the total received power received for a current cycle as background power, if the received power of the current cycle is less than stored background power of a previous cycle;
- and
- a subtractor for generating a rise over thermal (ROT) value representing the uplink load by subtracting the background power from the total received power of the base station measured when the received power of the current cycle is equal to or greater than stored background power of the previous cycle.
A method of measuring and reporting uplink load in a base station in a cellular mobile communication system, comprising the steps of:
- determining a measuring period for background power;
- outputting the minimum value of the total received power of the base station received for the determined measuring period as background power;
- and
- generating a rise over thermal (ROT) value representing the uplink load by subtracting the background power from the total received power for a non-measuring period.
