Cross Radio Access Technology Access with Handoff and Interference Management Using Communication Performance Data
First Claim
1. A multi radio access controller (RAT) module coupled to a plurality of core networks that service a plurality of user equipment (UEs) and access points (APs), comprising:
- a performance metric module configured to measure a first and second performance metric corresponding to communications between a UE from among the plurality of UEs and a first and second core network, respectively, from among the plurality of core networks; and
an access/handoff module configured to cause the UE to be serviced by the first or the second core network based on which of the first or second performance metric indicates better communications performance.

Abstract
Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.
