* A crucial part of QoS in mobile communications is Grade of Service, involving outage probability ( the probability that the mobile station is outside the service coverage area, or affected by co-channel interference, i. e. crosstalk ) blocking probability ( the probability that the required level of QoS can not be offered ) and scheduling starvation.

In a Loss System, the Grade of Service is described as that proportion of calls that are lost due to congestion in the busy hour.

For a Lost Call system, the Grade of Service can be measured using Equation 1.

For a delayed call system, the Grade of Service is measured using three separate terms:

Time t is chosen by the telecommunications service provider so that they can measure whether their services conform to a set Grade of Service.

The Grade of Service can be measured using different sections of a network.

If the Grade of Service is calculated based on the number of calls rejected by the final circuit group, then the Grade of Service is determined by the final circuit group blocking criteria.

If the Grade of Service is calculated based on the number of rejected calls between exchanges, then the Grade of Service is determined by the exchange-to-exchange blocking criteria.

The Grade of Service should be calculated using both the access networks and the core networks as it is these networks that allow a user to complete an end-to-end connection.

Furthermore, the Grade of Service should be calculated from the average of the busy hour traffic intensities of the 30 busiest traffic days of the year.

As in circuit-switched networks, the Grade of Service can be calculated for individual switches or for the whole network.

The telecommunications provider is usually aware of the required Grade of Service for a particular product.

To achieve and maintain a given Grade of Service, the operator must ensure that sufficient telecommunications circuits or routes are available to meet a specific level of demand.

It follows that in order for a telecommunications network to continue to offer a given Grade of Service, the number of circuits provided in a circuit group must increase ( non-linearly ) if the traffic intensity increases.

To calculate the Grade of Service of a specified group of circuits or routes, Agner Krarup Erlang used a set of assumptions that relied on the network losing calls when all circuits in a group were busy.

The probability of congestion gives the Grade of Service experienced.

To determine the Grade of Service of a network when the traffic load and number of circuits are known, telecommunications network operators make use of Equation 2, which is the Erlang-B equation.

This equation allows operators to determine whether each of their circuit groups meet the required Grade of Service, simply by monitoring the reference traffic intensity.
