20150126201 | NON-PERSISTENT HETEROGENEOUS NEIGHBORS - A heterogeneous network comprising macro network devices and micro network devices operates to maintain a dynamic data set of neighbor relations for a potential transfer of a User Equipment (UE) device from one network zone to another network zone. In response to detecting a failure of a macro network device to establish a network connection with a network device, a dynamic management of the data set initiates. A capacity number of network connections is determined for the macro network device (e.g., macro eNB sector carrier) based on the data set of neighbor relations. A threshold number is determined from the network neighbor device data, representing the set of micro network devices with which the macro network device is operable to establish the network. A defined number of micro network devices is maintained that is less than the threshold number of the network neighbor device data. | 05-07-2015 |

This predefined criterion is e.g. a need at the UE to request network resources for uplink transmission by the UE.
