摘要：
Protection of real-time data such as voice data exchanged as packets between a mobile electronic device (10) and a VPN gateway (122) during a media session over a communications link (130) that includes a wireless network (132). A first VPN connection (136) is established between the mobile electronic device (10) and the VPN gateway (122) through the communications link (130), the first VPN connection (136) using key-based encryption to protect data exchanged therethrough. While the first VPN connection (136) is established, a second VPN connection (138) is established between the mobile electronic device (10) and the VPN gateway (122) through the communications link (130), the second VPN connection (138) using key-based encryption to protect data exchanged therethrough. Real-time data packets are exchanged between the mobile electronic device (10) and the VPN gateway (122) through the second VPN connection (138).
