A computer implemented method of selective transmission of a communications message from a home telecommunications network to a visited telecommunications network for delivery to a subscriber device roaming via the visited network, the method comprising: receiving the message at the home network; identifying a communications component of the visited network to which the messages is to be routed; defining an input vector for a classifier, the input vector encoding parameters of the communications component; executing the classifier to classify the communications component to determine a reliability state of the communications component; and forwarding the message to the communications component of the visited network for delivery to the subscriber device in dependence on the classified reliability state.

In order to more quickly detect a failure in a radio base station and complement the coverage thereof, a first base station included in a communication system forms a first cell to conduct radio communication with one or more mobile stations. A second base station, which is placed adjacent to the first base station, forms a second cell to conduct radio communication with one or more mobile stations. The first base station conducts communication with the second base station to monitor whether or not a failure occurs in the second base station. When it is detected as a result of the monitoring that the failure occurs in the second base station, the first base station expands coverage of the first cell so as to complement that of the second cell.

There is provided mechanisms for routing packets between a terminal device and a control system node via intermediate nodes on wireless paths in a wireless network. A method includes obtaining information on disturbances of wireless paths used for communicating packets of a traffic flow between the intermediate nodes in the wireless network. The method includes determining, based on the information on disturbances, mutual correlation between the disturbances of the wireless paths. The method includes routing the packets of the traffic flow between the terminal device and the control system node via some of the intermediate nodes and along disjoint wireless paths, whereby the packets are transmitted in parallel on the disjoint wireless paths, and wherein the disjoint wireless paths have mutual correlation not higher than a threshold correlation value.

Techniques are directed to determining a rank value associated with a first network node. An example method includes determining a second network node indicated as being a preferred parent network node for the first network node. A first rank value is processed to determine a second rank value, the first rank value corresponding to a path from the second network node to a destination network node, including rounding up the first rank value in a predetermined manner to at least a second next higher integral rank value than the first rank value, to determine the second rank value. The second rank value is processed with at least a third rank value to determine the rank value associated with the first network node, the third rank value associated with a path from one of a plurality of candidate parent network nodes, for the first network node, to the destination network node.

A method and apparatus are disclosed for using alternate paths for descendant nodes for backhaul failure link reporting. In one embodiment, a method for a network node that may be a parent node includes receiving information indicating at least one alternate path of at least one child IAB node to an IAB donor node, the at least one child IAB node being a wireless backhaul node; and using the received information to perform at least one of a backhaul wireless link failure recovery and load balancing of traffic. In another embodiment, a method for a network node that may be a child node includes receiving information indicating at least one alternate path of a parent IAB node to an IAB donor node, the parent IAB node being a wireless backhaul node for the child IAB node. The received information is used to perform at least one operational task.

In aspects of managing FTM frames of WLAN RTT bursts, a device can receive a WLAN RTT burst, such as initiated by a device application, device firmware, or received as a RTT ranging request. The device implements a status module that interposes the routing of the ranging request in the device, and determines a device state of the device with a device state monitor of the status module. The status module is implemented to drop the ranging request if the device is an idle device state such that the ranging request is extraneous. Alternatively, the status module is implemented to reduce a number of FTM frames in the ranging request based on the device state indicating that multiple FTM frames of the ranging request are extraneous, and then route to perform the ranging request of the WLAN RTT burst with the reduced number of FTM frames in the ranging request.
