Mobile units are handed over from LTE to carrier grade WiFi. The LTE can be licensed (LTE-L) or unlicensed (LTE-U), Charging mechanisms for co-located and integrated WiFi are also provided. When an LTE-U capable mobile unit moves into the LTE-U coverage area of a small cell, the mobile unit can use the unlicensed spectrum, for a data session, thereby effectively increasing the data capacity of the network. When the mobile unit moves within the carrier grade Wi-Fi coverage area of the small cell, the small cell can handover the entire data session to the carrier grade Wi-Fi access point, thereby freeing up LTE system, resources to provide data services to other mobile units. |
