Indicating the probability of a subscriber being active at a given instant of time by analysing a temporal history of activity

摘要

The invention relates to scheduling transmission of messages, such as advertisement messages, targeted to one or more subscribers 111, 112, 151 of a communication network 103. The transmission of the messages is scheduled at least partly on the basis of statistical characteristics of behaviour of the subscribers 111, 112, 151. The statistical characteristics of the behaviour of the subscribers 111, 112, 151 are based at least partly on temporal history of activity of the subscribers 111, 112, 151 in the communication network 103 and are formed using appropriate statistical methods on the basis of observed activity of the subscribers 111, 112, 151. The statistical characteristics of behaviour of the subscribers 111, 112, 151 are arranged to indicate a value of probability that each subscriber 111, 112, 151 is active at a given instant of time. Hence, the number of messages that are targeted to subscribers 111, 112, 151 not accessible via the communication network 103 at a given time may be reduced.
