System and method for providing communication connection resilience

摘要

A system and method for providing communication connection resilience between a mobile subscriber device and a network, such as the Internet. In one aspect, the invention provides improved communication connection resilience by using multiple nodes in multiple chassis to create redundant communication routes and to provide redundancy for control data relating to a mobile subscriber device. In one embodiment, a first node resides in a first chassis and a second node resides in a second chassis, and when an active communication link between the mobile subscriber device and the network via the first node becomes disrupted, the active communication link is rerouted such that data is communicated between the mobile subscriber device and the network via both of the first and second nodes.

1. A system for providing communication connection resilience between a mobile subscriber device and a network, the system comprising:
a first node residing in a first chassis, the first node in communication with the mobile subscriber device, and configured to provide an active communication link between the mobile subscriber device and the network; and a second node residing in a second chassis, the second node in communication with the mobile subscriber device and with the first node, and configured to provide a non-active communication link to the network; the first node including a first transceiver, a first processor, and a first database, the first database configured to store control information relating to the mobile subscriber device, and the first processor configured to update the control information; the second node including a second transceiver, a second processor, and a second database, the second database configured to store the control information relating to the mobile subscriber device; wherein, when the control information relating to the mobile subscriber device is updated by the first processor, the first transceiver transmits the updated control information to the second transceiver; and wherein when the active communication link between the mobile subscriber device and the network via the first node is disrupted, the first processor reroutes the active communication link between the mobile subscriber device and the network to include both of the first node and the second node, wherein when the active communication link is disrupted between the mobile subscriber device and the first node, the first processor reroutes the active communication link such that first traffic is transmitted from the mobile subscriber device to the second transceiver, then from the second transceiver to the first transceiver, then from the first transceiver to the network, and such that second traffic is transmitted from the network to the first transceiver, then from the first transceiver to the second transceiver, then from the second transceiver to the mobile subscriber device.
