Abstract: The use of wireless backhaul poses special challenges for in-vehicle base stations. Users that are connected to an in-vehicle base station expect continuous service, even as the in-vehicle base station passes in and out of different wireless backhaul coverage zones, such as when a train passes from a train station with good coverage to a tunnel with poor coverage. The base station thus needs seamless backhaul handover. A system that enables an in-vehicle base station to receive continuous service across different backhaul coverage zones is needed. To solve this problem, a system enabling handover is described. The system involves double-tunneling mobile device data packets in an ESP-UDP IPsec tunnel encapsulated in a GTP-U tunnel. Traffic is transmitted from a mobile device to a specially configured base station that encapsulates mobile device data packets and sends them to the network via wireless backhaul using an LTE UE modem connection.

Abstract: Methods are disclosed for incorporating a security gateway within a wireless mesh network. In one embodiment, the wireless mesh network is a heterogeneous mesh network. In one embodiment, a gateway node, which is part of the wireless mesh network, requests a connection to the core network through a security gateway. The security gateway responds by creating an IPSec tunnel and a GRE tunnel within the IPSec tunnel from itself to the gateway node. Once the gateway node is communicatively coupled to the security gateway via secure tunneling, the gateway node sends a mesh routing protocol to the security gateway.
