Analysis of dynamic reservation schemes for cellular networks

På svenska

Author

Summary, in English

Out of Quality of Service reasons, higher priority shall in cellular networks be assigned to ongoing connections than to new call attempts. In order to improve the efficiency of the bandwidth reservation scheme, the amount of bandwidth to reserve for high priority connections can be made time-varying and adaptive towards the momentary network conditions. Subscriber movement predictions can be applied to obtain handover arrival rate estimations, which can be used as input to the bandwidth reservation allocation procedure. The subscribers can for instance be grouped according to speed and previous cells. In this paper, a Markovian analysis of such prediction-oriented grouping features will be performed. The obtained analytical results will be validated using computer simulations.
