METHOD AND DEVICE FOR SECURING HANDOVER BETWEEN WWAN AND WLAN

摘要

The invention proposes a method to be executed by a user equipment UE communicating via a first communication network with another communication device, comprising the steps of : detecting whether to be able to communicate with the another communication device via a second communication network; negotiating with the another communication device via the first communication network for base information for generating a key if the second communication network is available; generating the key based on the negotiated base information according to the predetermined encryption algorithm; sending the information encrypted with the key to the another communication device via the second communication network.
