Sony patents wireless handover method for mobile network nodes
Sony has been granted a patent for a method to manage wireless connections in a telecommunications network. The system allows a main base station to switch a mobile node, which acts as a relay for other devices, to a different base station. During this switch, the main station sends specific configuration data to ensure the connected devices maintain their connection without interruption.
In the filing’s own words
An infrastructure equipment for providing a wireless interface to a communications node in a wireless communications network, the infrastructure equipment configured to support a wireless backhaul configuration for the communications node, wherein in the wireless backhaul configuration the communications node is configured to provide a wireless backhaul between one or more communications devices and the infrastructure equipment, the infrastructure equipment configured to: transmit one or more handover requests including first node configuration information for the communications node and first device configuration information for each of the one or more communications devices; receive one or more handover request acknowledgements; determine second device configuration information based on the one or more handover request acknowledgements; and transmit, to the first communications device, the second device configuration information for the first communications device.
What exactly they claim (claim 1)
1. An infrastructure equipment for providing a wireless access interface to a communications node in a wireless communications network, the infrastructure equipment configured to support a wireless backhaul configuration for the communications node, wherein in the wireless backhaul configuration the communications node is configured to provide a wireless backhaul between one or more communications devices and the infrastructure equipment, the infrastructure equipment comprising: a transmitter configured to transmit, via the wireless access interface, signals to the communications node; a receiver configured to receive, via the wireless access interface, signals from the communications node; and a controller configured to determine to handover the communications node to another infrastructure equipment; wherein the controller is further configured to operate with the transmitter and receiver to: transmit, to the other infrastructure equipment, one or more handover requests including (1) first node configuration information for configuring a connection between the infrastructure equipment and the communications node and (2) first device configuration information for each of the one or more communications devices; receive, from the other infrastructure equipment, one or more handover request acknowledgements; determine second device configuration information based on the one or more handover request acknowledgements, wherein the second device configuration information for a first communications device of the one or more communications devices is different to the first device configuration information for the first communications device; transmit, via the communications node and to the first communications device, the second device configuration information for the first communications device.
