20090161669 | Evolution of Ethernet Networks - An Ethernet network comprises nodes which support a plurality of different forwarding modes. A range of VLAN Identifiers (VIDs) are allocated to each of the forwarding modes. Connections are configured between a source node and a destination node of the network using different forwarding modes. Packets carrying data traffic are sent to the destination node by selectively setting a VID in a packet to a first value, to transfer a packet via a first connection and a first forwarding mode, and a second value to transfer a packet via the second connection and the second forwarding mode. Packets received from both of the connections and sent on to an end-user. VLAN Identifiers can be allocated to different releases of functionality at nodes (e.g. software releases) such that packets are forwarded via a set of nodes supporting a first release, or via a set of nodes supporting a second release. It is possible to provide a controlled and disruption-free network evolution. | 06-25-2009 |

20140105176 | Circuit Bearer Control - The invention makes use of the Short Message Service (SMS) or Unstructured Supplementary Services Data (USSD) capabilities present in today's cellular networks as a means of providing call control and presence signalling and, in particular, for providing the means of effecting hand-off at least from/to the cellular domain to/from the WiFi domain. SMS and USSD were originally designed as engineering channels, but SMS has become highly popular as a service in its own right. SMS and USSD are built into all existing cellular (GSM, CDMA etc.) network and predate the current GPRS overlay. In particular, SMS and USSD can be used while a call may be active in the cellular domain, and a handset may send and receive such messages, with an additional facility which may be used by the invention of receiving acknowledgements of successful receipt of an outgoing SMS by the messaged party—effectively a confirmation from the network. The present invention proposes to use SMS or USSD as a means of an adjunct call control and presence signalling in the cellular domain between a handset and the SIP domain. | 04-17-2014 |
