Claim 18:
19. A method of operating an infrastructure equipment acting as a relay node forming part of a wireless communications network comprising a plurality of other infrastructure equipment, the infrastructure equipment acting as the relay node and the plurality of other infrastructure equipment each being configured to communicate with one or more others of the infrastructure equipment via a backhaul communications link, one or more of the infrastructure equipment each being configured to communicate with one or more communications devices via an access link, the method comprising:
relaying signals representing data between a second of the infrastructure equipment to a first of the infrastructure equipment, the first infrastructure equipment acting as a donor node connected to a core network part of the wireless communications network, the signals being relayed over a first communications path via at least the infrastructure equipment acting as the relay node, the second infrastructure equipment being a child node and the infrastructure equipment acting as the relay node or the donor node being a parent node, the parent node being connected to the child node via a backhaul communications link and configured to allocate uplink communications resources to the child node,
determining that a trigger condition for the child node to communicate with the donor node over a second communications path via one or more other of the infrastructure equipment acting as relay nodes is satisfied, the second communications path being different to the first communications path, and
transmitting a route change command to the child node, the route change command indicating that the child node should communicate with the donor node over the second communications path,
wherein the determining that the trigger condition is satisfied comprises at least a determination that at least one quality of service requirement cannot be guaranteed by the parent node.
