In some examples, a method can include determining a number of mobile stations that have been used by users to implement a call during a period of time using a base station of a telecommunications network based on traffic data, and determining that the number of mobile stations is equal to or within a value or range of a base station support threshold for the base station, which indicates that there is a probability that a given mobile station of mobile stations will be blocked or denied access from initiating a respective call in using the base station. The method further can include determining a number of additional channels that are needed for the base station to reduce the probability that the given mobile station of the mobile stations will be blocked or denied access from initiating the respective call in the future using the base station.
