Abstract: Systems and methods are described for determining candidates for handover of wireless devices in a wireless network. A first access node in communication with one or more wireless devices may receive signal information for second access nodes from the wireless devices. A communication link between the first access node and each second access node may be used to transmit second access node network characteristics to the first access node. The first access node may store information about second access nodes in a neighbor relation table. If a removal condition is satisfied, one or more second access nodes may be removed from the first access node neighbor relation table and may be blacklisted. Blacklisted second access nodes may be monitored for improvements in signal information or network characteristics. Improved second access nodes may be removed from the blacklist based on a comparison with threshold values for signal information and network characteristics.
