Abstract
A telecommunications network termination device has the capability to connect to a network access point using a primary fixed line address by a first route and also, using a second network address, by a backup routing to a shared wireless access point. Connection status messages are transmitted over the primary routing. If these are not detected by the network, it causes traffic to the user device to be diverted over the backup routing to the second network address. It also transmits instructions to the user device to route outgoing traffic by the same secondary route. The secondary route is identified from network tolopogy data stored by the network control server.
Claims9
A telecommunications network having one or more network termination devices, and having provision for communications addressed to a given network termination device to be routed to a primary network address, means for associating a secondary network address with the primary network address, the or each network termination device having monitoring means for detecting a loss of connectivity between the network and the primary network address, and means for causing the network termination device to connect with the network over a secondary routing using the secondary network address when such loss of connectivity is detected.
A telecommunications network termination device having user device connection means for connection to one or more computing devices, and at least two network connection means, the first network connection means having a first network address for communicating with a network by way of a primary routing, and a second network connection having means for communicating with a network using a second network address by way of a secondary routing, further comprising monitoring means for identifying a failure of communication with the network by the first connection means, and means for diverting connection to the secondary connection means using the second network address when such failure is detected.
A method of operating a telecommunications system in which connection between a network termination device and a network may be made by means of a primary routing having a first network address or by an alternative, secondary routing, having a second network address, between the termination device and the network, and wherein if the network termination device detects a failure in the primary routing, the termination device generates a message to the network to cause traffic to and from the termination device to be diverted over the secondary routing using the second network address.
