Abstract
A wireless network for addressing the unavailability of airlink connection resources (“resources”) is disclosed. A plurality of smaller cells are dynamically created within the coverage boundary of a macrocell, wherein each smaller cell is capable of providing the same resources available from the macrocell. The network further addresses the inefficient “push” schema for handover of services from one node to another. Nodes within each of the plurality of smaller cells continuously scan other nodes to measure resources used by the other nodes for handover using a “pull” schema. The measurement tells a node if it is capable of providing at least a minimum grade of service, and if so, the node informs the subscriber device. If the measurement is mutually valid, the current node initiates the handover to the node. After the handover, the new node continues to provide the at least minimum grade of service.
