1. A method comprising:
electronically generating an index having a plurality of available primary nodes and a plurality of bins, each of the plurality of available primary nodes corresponding to one of the plurality of bins;
determining a user device is concurrently connected to a secondary node and a primary node, wherein the primary node currently connects the user device to a wireless network;
determining a timing advance value and an angle of arrival value of the user device currently connected to the primary node;
determining that the timing advance value and the angle of arrival value correspond to a particular bin in the plurality of bins of the index;
identifying an optimal primary node in the plurality of available primary nodes, the optimal node corresponding to the particular bin to which the timing advance value and the angle of arrival value of the user device are determined to correspond; and
communicating an assist notification to the primary node, the assist notification triggering the primary node to send a handover communication to the user device and cause the user device to connect to the optimal primary node.
