Performance analysis of cell zone partitioning in bandwidth reservation schemes
Författare
Summary, in English
Bandwidth reservation is a procedure that can be applied to give higher priority to certain connection types in cellular networks. Subscriber movement predictions can be used to determine the amount of bandwidth to be reserved in each cell. The prediction accuracy is significantly unproved if both the approximate subscriber locations in the cell and stored subscriber movement data are taken into account in the prediction procedure. The obtained accuracy improvement reduces the call blocking and/or handover dropping probabilities in the network. In this paper, the efficiency of including a cell zone partitioning feature in the bandwidth reservation procedure will be studied. Each cell is partitioned into smaller cell areas, denoted zones, and it is continuously tracked in which zone every single ongoing call is located. Different zone configurations and subscriber mobility parameters as well as the impacts of imperfect positioning will be considered in the performance analysis.
