Abstract
A secure communication channel between an access point (AP) device associated with a wireless network and a mobile gateway (GW) device of a packet core network is established. Data is exchanged between the wireless network and the packet core network through the secure channel. A client device (UE) is authenticated through the secure communication channel. Device identity information is received from the AP device. A session request is sent to the packet core network. An IP address for the device is received from the packet core network. The communication between the AP device and the packet core network becomes secure without need to run an IP secure protocol on the UE that saves the battery power on the UE. Establishing the fully secure communication between the UE and the packet core network while saving the UE power provides a significant advantage for the mobile technology world.
