Call volume (telecommunications) Redirected from Calls per second

In telecommunications, call volume refers to the number of telephone calls made during a certain time period. Depending on context, the phrase may refer to either the number of calls made to a specific physical area or telephone number (such as an emergency service) or the number of calls made between two or more areas (e.g. cities).

Calls Per Second or CPS refers to how many telephone calls can be handled in a second. CPS is one measure of the performance of Switching systems. It helps in estimating Busy-hour call attempts (BHCA) and Busy-hour call completion (BHCC) of Switching systems.

Various formulas exist to forecast the number of calls that might be made; another key distinction concerns whether long or short-term trends are to be predicted.[1]

Forecast Formulas

Perhaps the simplest formula used to forecast call volume is the linear equation

where y is the expected call volume, x is time, and m and b are constants.

However, this is suitable for long-term trends only,[1] and further assumes that growth will be linear. Another formula, seen in a mathematics textbook,[2] is the inverse square equation

where C is the number of expected calls between two cities (during one day), P1 is the population of the first city (in thousands), P2 is the population of the other city (also in thousands), and d is the distance between them (units unclear in the book, but probably miles).
