METHOD OF SWITCHING CONNECTION TO FEMTOCELL AND WIFI AP IN SDN

摘要

A method of switching a connection to a femtocell and a WiFi access point (AP) in software defined networking (SDN) capable of minimizing inconvenience of use by automatically switching a connection to a mobile communication network including the femtocell and a WiFi network connected to the SDN without disconnection of a data service in a state that a user does not recognize is provided.

1. A method of switching a connection to a femtocell and a WiFi access point (AP) in software-defined networking (SDN), wherein a mobile communication terminal is connected to the femtocell of a mobile communication network or the WiFi AP adjacent thereto connected to an SDN switch wirelessly in SDN including the SDN switch and an SDN controller separated from the SDN switch and configured to control the SDN switch, the method comprising:
(a) detecting that the mobile communication terminal enters, and reporting the detecting fact to the SDN controller through the SDN switch, by the femtocell; (b) instructing the mobile communication terminal to connect to the adjacent WiFi AP by activating a WiFi module of itself through the SDN switch and the femtocell, by the SDN controller; and (c) connecting to the WiFi AP after activating the WiFi module of the mobile communication terminal itself in a state that the mobile communication terminal is connected to the femtocell, by the mobile communication terminal.
