Abstract: A communications system may include a data collection server (DCS) that receives contextual information from a set of UE devices. The DCS may aggregate the contextual information into a database. A given UE may proactively identify an optimal network configuration to use in communicating with a cellular network. The UE may generate local contextual information. The UE may request a set of entries from the database corresponding to a set of geographic tiles overlapping or neighboring its location. The UE may select the optimal network configuration based on its local contextual information and the requested entries. The UE may transmit a request to a base station to perform communications under the optimal network configuration using user equipment assistance information (UAI) of a radio resource control (RRC) signal. Proactive selection of the network configuration may optimize performance given the current UE operating context without requiring reactive network configuration adjustments.
