Secure and seamless handover between IP-based cellular networks and Wi-Fi networks
First Claim
1. A method of offloading data from a cellular network to a Wi-Fi network, comprising:
- receiving a request from a user equipment (UE) to connect to a Wi-Fi network;
determining that the UE is a subscriber to a cellular network;
determining whether to offload data from the cellular network to the Wi-Fi network based at least in part on a set of offload criteria;
obtaining a Home IP Address, wherein the Home IP Address comprises a mobile IP address corresponding to the UE assigned by the cellular network;
allocating the Home IP Address to the UE as the UE'"'"'s IP address for communicating with the UE on the Wi-Fi network; and
offloading data from the cellular network to the Wi-Fi network.

Abstract
A method of offloading data from an IP-based cellular network to a Wi-Fi network is disclosed. A request from a user equipment (UE) to connect to a Wi-Fi network is received. It is determined whether the UE is a subscriber to a cellular network. It is determined whether to offload data from the cellular network to the Wi-Fi network. The determination is based at least in part on a set of offload criteria. A Home IP Address is obtained, wherein the Home IP Address comprises a mobile IP address corresponding to the UE assigned by the cellular network. The Home IP Address is allocated to the UE as the UE'"'"'s IP address for communicating with the UE on the Wi-Fi network. Data is offloaded from the cellular network to the Wi-Fi network.
