Using statistical data for reliable mobile communications

摘要: We examine the extent to which statistical mobility information can increase reliability of service experienced by users in mobile networks. Interrupted or dropped calls are an aspect that stems from users. An existing user move a cell where there no resources available support their call. A natural solution is reservation multiple cells likely to. This scheme called selective reservations and it relies on predicting next user. Recently, has been some work estimating movement probabilities (also known as profile) In this paper, we quantify usefulness profile improve perceived identify two parameters characterize profile: Accuracy Focus. expresses probability host will expect Focus describes how well patterns our simulations, effect quality predictions performance system. show have great impact reservations. also flexibility hand-offs help decreasing dropping probability, be facilitated letting make second try at moving case fails first time.
