Abstract:
1. A method comprising: generating, by a controller apparatus that communicates with a plurality of wireless radio access point devices that serve wireless client devices in a wireless network, data to assign two or more of the wireless radio access point devices into groups; generating, by the controller apparatus, coordinating data for each group of radio access point devices to coordinate a neighbor discovery session during which a particular radio access point device in the group is configured to transmit a signal at maximum power in a time interval during which all other radio access point devices in the group attempt to receive the signal, and to repeat the same during other time intervals of the neighbor discovery session during which a different radio access point transmits a signal at maximum power, until all of the radio access point devices in the group have transmitted; sending the coordinating data from the controller apparatus to each radio access point device in the group; receiving, by the controller apparatus, discovery results from each radio access point device in the group, wherein the discovery results comprise, for a given radio access point device, data pertaining to signals received during the neighbor discovery session; generating, by the controller apparatus, a neighbor list for each radio access point device in a group based on the discovery results, wherein the neighbor list contains a list of identifiers of radio access point devices that are candidates for handover of service; and sending the neighbor list from the controller apparatus to each radio access point device.
