A layer assignment and resource reservation scheme for hierarchical cell structures

Summary, in English

To provide for a high QoS in a cellular network, each call should be assigned to its preferred cell and priority given to already ongoing calls. Herein, a combined speed-sensitive layer selection method and dynamic guard channel scheme, called CLARR, for use in hierarchical networks, is introduced. To reduce the complexity, partially the same speed estimation and measurement procedures are applied for both tasks. The main features of CLARR are the use of dwell time feedback control in the layer selection method and the grouping of calls depending on previous movement patterns. The measurements needed for making mobility predictions are performed separately for calls of different groups.
