  • Patent number: 10021521
    Abstract: A Long-Term Evolution (LTE) communication system to facilitate updating network topology information when a mobile wireless repeater changes its attachment comprises a network topology server, a former macro LTE base station to which the mobile wireless repeater was previously attached, and a new macro LTE base station to which the mobile wireless repeater is presently attached. The network topology is server configured to receive updated attachment information transmitted from the mobile wireless repeater and transfer an attachment scan instruction for delivery to the former macro LTE base station and the new macro LTE base station. The former and new macro LTE base stations are configured to determine network attachment information for one or more network wireless repeaters and transfer the network attachment information for delivery to the network topology server. The network topology server is further configured to receive the network attachment information and update a network topology map.
