Description of the tolerant limits algorithm
The number of calls/sessions required to ensure proper accuracy shall be estimated using a formula relating the probability P (S < s) of the number of failed calls/sessions not exceeding s to a given loss rate of calls/failed sessions p and the number of attempted calls/sessions n:
where
n – number of call/session attempts;
k – number of failed call/session attempts;
S<s – the condition of violation of the rate of failed calls/sessions;
pk– probability of failed calls;
pk (1-p)n-k – the probability that after n calls/sessions, k of them were failed;
Applying the formula yields two calculation points:
The compliance limit shall be based on the inverse probability formula:
where
Q – boundary of guaranteed norm compliance;
P – confidence probability.
In such a case, the values of s and n shall fulfil the condition: if after making n calls the number of lost calls/failed sessions does not exceed s, then the rate of lost calls/failed sessions will be p with a confidence probability P.
The boundary of guaranteed violation of the norm, if a solution is sought for P (S < s), then the values of s and n found comply with the following condition: if after n calls/sessions the number of failed calls/sessions is greater than s, then the norm of the proportion of failed calls/sessions p will be violated with confidence probability P.
The boundaries for the rate of failed calls out of the total number of calls to a cellular network subscriber (p = 3.0 %) and the rate of failed sessions (p = 5.0 %) are shown in the following table:
p = 3.0 % | p = 5.0 % | |||||||
n - total number of calls/sessions | s - number of failed calls/sessions | Share of failed calls/sessions, % | n - total number of calls/sessions | s - number of failed calls/sessions | Share of failed calls/sessions, % | n - total number of calls/sessions | s - number of failed calls/sessions | Percentage of failed calls/sessions, % |
