An apparatus, method of operating the apparatus, and system comprising the apparatus are provided. The apparatus has a backhaul sub-node to provide a backhaul connection to a communications network and an access sub-node to provide an access cell to which user equipment can connect. In response to a configuration trigger a configuration procedure is performed, in which the backhaul sub-node gathers information about the network environment and transmits at least a portion of the information about the network environment to a network management node. The the network management node then generates an access sub-node configuration which it transmits to the access sub-node, where the configuration is dependent on the information about the network environment transmitted to the network management node by the backhaul sub-node. The backhaul sub-node's greater ability to gather information about the network environment thus supports an improved configuration for the access sub-node, without technical input from the user being required.

Access node configuration in a network

There is provided a node that includes radio circuitry that wirelessly connects to other devices in a wireless network using either a first radio configuration or a second radio configuration. Scan circuitry determines a first measurement related to using the radio circuitry to connect to an analysed device in the other devices in the first radio configuration and a second measurement related to using the radio circuitry to connect to the analysed device in the second radio configuration. Metric calculation circuitry calculates, for each device in the other devices, a metric, wherein each metric is calculated by applying a first weighting greater than zero to the first measurement obtained for that device and a second weighting greater than zero to the second measurement obtained for that device. Selection circuitry adapted to select one of the other devices in dependence on the metric calculated for each of the other devices.

Metrics using parameters for multiple radio configurations

An apparatus and method of performing a configuration process in the apparatus are provided. The apparatus has a backhaul sub-node to provide a backhaul connection to a communications network which comprises a proxy system. It also has an access sub-node to provide an access cell to which user equipment can connect. In a configuration process the backhaul sub-node performs a backhaul sub-node auto-configuration process comprising connecting to a further network node, determining backhaul sub-node configuration parameters, and storing in the proxy system at least one configuration parameter for the access sub-node in dependence on the backhaul sub-node configuration parameters determined. When the access sub-node then issues an access sub-node auto-configuration request, the proxy system intercepts the access sub-node auto-configuration request and responds to the access sub-node in dependence on the at least one configuration parameter for the access sub-node stored. Transparent to the access sub-node, the backhaul sub-node can thus modify the default configuration which the access sub-node would receive, based on the specific backhaul connectivity which it has established for itself.

Network access sub-node configuration by a proxy

A bandwidth packing rate control technique includes altering bandwidth allocations of existing flows on a link depending on a current utilization of a current bandwidth allocation for a flow. A disclosed example decreases the bandwidth allocation for flows that are utilizing a current bandwidth allocation below a selected target utilization rate. Flows with higher utilization can receive increased bandwidth allocation, which provides increased throughput for such flows. One overall result of a disclosed example is increased utilization and increased throughput using existing bandwidth resources.

Bandwidth packing rate controller for optimizing resource utilization

By approximating a packet network, such as the Internet, by an M/M/1 queuing model, the available bandwidth of the network can determined from the variance of the distribution of the sojourn times of packets transmitted through the network. In order to determine the variance of the distribution of sojourn times, and thus the bandwidth of the packet network that is available for transport of packets from an input to an output, a probe train of N packets with known inter-packet intervals is injected from an input on a sending side of the network. At the receiving side of the network, the packet arrival times are measured and the inter-packet intervals of each pair of received packets in the received train are calculated and compared with the known inter-packet interval times of the corresponding input packets. The variance of the distribution of the sojourn times of the packets through the network can then calculated using these time differences even though the individual sojourn times of the packets through the network cannot be directly measured.
