A notification server is provided for a multi-network wireless communication system. The notification server includes a processor and a memory having computer executable instructions stored therein. The instructions, when executed by the processor, cause the processor to receive first device information from a mobile communication device wirelessly connected to a macro cell network of the multi-network wireless communication system. The instructions further cause the processor to determine, based on the received first device information, that a small cell network of the multi-network wireless communication system is available for communication with the mobile communication device. The instructions further cause the processor to transmit a notification to the mobile communication device to search for the small cell network for transition thereto.
