NETWORK INITIATED EVOLVED PACKET CORE (EPC) AND IP MULTIMEDIA SUBSYSTEM (IMS) NETWORK USAGE OPTIMIZATION ALGORITHM FOR LTE CAPABLE SMARTPHONES CONNECTED TO WIRELESS LAN(WI-FI) NETWORK

摘要

According to some embodiments, an. LTE node determines, that a wireless device is in radio resource control. (RRC) idle mode and starts an inactivity timer Tw. In response to expiry of the inactivity timer Tw, the LTE node directs the wireless device to a legacy node.
