Abstract

The present invention is a novel and improved method for monitoring the real time loading condition in a CDMA wireless communication system. The level of the power control signal is obtained by monitoring, in real time, at the base station the forward link CDMA channel, comparing this measurement to the previously obtained level, and displaying the level of the power control signal as a line which can consist of two parts. The first part can be a solid line the length of which represents the level of the power control signal in real time and the second part can be a dotted line whose length increases slowly and decreases rapidly to indicate that the level of the power control signal is rising. Conversely, a rapid increase and a slow decrease of the length of the dotted line indicates that the level of the power control signal is falling. Color coding can be used to indicate that the level of the power control signal is at or outside an optimum operating range.

Claims

1. A method for displaying in real time the level of the power control signal at a base station in a CDMA network comprising a plurality of microcells controlled by the base station, and at least one mobile terminal served by the microcells, the method comprising

obtaining the current level of the power control signal and

displaying the current level of the power control signal to show in real time the level of the power control signal relative to a threshold level where a less than optimum operating condition can occur in the operation of the CDMA network, the step of displaying the current value of the power control signal comprises:

displaying a line, the length of which represents the current level of the power control signal; and

identifying a location along the path of the line which marks where a less than optimum operating condition can occur in the operation of the network, the step of identifying a location comprises a first fixed zone to identify a lower power threshold level, a second fixed zone to identify an upper power threshold level, wherein the line that displays the real time level of the power control signal appears as a first color if displaying desired power control levels and a second if when displaying power control levels that are not desired, the line appearing in two parts, the first part comprising a continuous line the length of which represents the actual real time level of the power control signal and the second part comprising a broken line which increases in length to indicate that the level of the power control signal is increasing or decreases in length to indicate that the level of the power control signal is decreasing.

2. A method of displaying in real time the level of the power control signals a base station in a CDMA network comprising a plurality of microcells controlled by the base station and at least one mobile terminal served by the microcells, the method comprising:

obtaining the current level of the power control signal, storing the obtained current level of the power control signal;

obtaining at a subsequent time, a second current level of the power control signal;

comparing the second current level of the power control signal with the stored level of the power control signal to determine if the level of the power control signal is increasing, decreasing or remaining unchanged;

displaying the second current level of the power control signal to show the real time level of the power control signal; and

indicating whether the level of the power control signal is increasing, decreasing or remaining unchanged, wherein the step of displaying the level of the power control signal comprises;

a line, the length of which represents the real time level of the power control signal; and

setting a threshold location to which the line can approach, the location marking a level beyond which a less than optimum operating condition can occur in the operation of the network, the step of setting a threshold location comprises setting a first threshold location to identify a lower power threshold level and a second threshold location to identify an upper power threshold level,

wherein the line that displays the real time level of the power control signal is a first color if the level of the power control signal is between the lower and upper power threshold levels and a second color if the level of the power control signal is below the lower threshold level or above the upper threshold level, the line having two parts, the first part comprising a continuous line the length of which represents the actual real time level of the power control signal and the second part comprising a dotted line which slowly increases and rapidly decreases in length from the end of the first part to indicate that the level of the power control signal is increasing.

3. A method of displaying in real time the level of the power control signals a base station in a CDMA network comprising a plurality of microcells controlled by the base station and at least one mobile terminal served by the microcells, the method comprising:

obtaining the current level of the power control signal, storing the obtained current level of the power control signal;

obtaining at a subsequent time, a second current level of the power control signal;

comparing the second current level of the power control signal with the stored level of the power control signal to determine if the level of the power control signal is increasing, decreasing or remaining unchanged;

displaying the second current level of the power control signal to show the real time level of the power control signal; and

indicating whether the level of the power control signal is increasing, decreasing or remaining unchanged, wherein the step of displaying the level of the power control signal comprises;

a line, the length of which represents the real time level of the power control signal; and

setting a threshold location to which the line can approach, the location marking a level beyond which a less than optimum operating condition can occur in the operation of the network, the step of setting a threshold location comprises setting a first threshold location to identify a lower power threshold level and a second threshold location to identify an upper power threshold level,

wherein the line that displays the real time level of the power control signal is a first color if the level of the power control signal is between the lower and upper power threshold levels and a second color if the level of the power control signal is below the lower threshold level or above the upper threshold level, the line having two parts, the first part comprising a continuous line the length of which represents the actual real time level of the power control signal and the second part comprising a dotted line which slowly decreases and rapidly increases in length from the end of the first part to indicate that the level of the power control signal is decreasing.
