Quality of service in wireless backhauls

Abstract

A feeder terminal comprises backhaul communication circuitry to connect to a communications network via a wireless backhaul, and provide an access base station with access to the wireless backhaul. Backhaul information circuitry determines congestion information relating to the wireless backhaul and communication circuitry enables communication with an access base station and provides the congestion information to the access base station. In response to a demand message from the access base station comprising quality of service requirements, the communication circuitry forwards the demand message to the communications network. Additionally, an access base station comprises communication circuitry to enable communication with a feeder terminal. Backhaul communication circuitry connects to acommunications network via a wireless backhaul provided by the feeder terminal, and provides the user equipment with access to the wireless backhaul. Requirement determination circuitry determines atleast one quality of service requirement from the user equipment; and access control circuitry selectively controls usage of the wireless backhaul by the user equipment. The communication circuitry provides a quality of service demand message to the feeder terminal based on the at least one quality of service requirement and receives congestion information relating to the wireless backhaul from the feeder terminal. The access control circuitry controls usage of the wireless backhaul by the user equipment in dependence on the congestion information.

Description

technical field [0001] This technology relates to the field of networking. In particular, the technology relates to quality of service in wireless feeder networks. Background technique [0002] Quality of Service (QoS) involves specific requirements placed on computer networks. For example, a live video application may have a QoS requirement to provide a bandwidth of 1.5 Mbit / s with a latency of 100 ms. Meeting QoS requirements relies on service guarantees, such as guarantees about the capacity or bandwidth of a particular connection. For example, a connection between two devices may have a service guarantee of 10 Mbit / s with a 50ms latency. [0003] In wireless networks, it has previously been proposed to provide service guarantees by statically allocating available bandwidth to different devices. For example, if a particular device X has 10 Mbit / s of available bandwidth and 10 other devices are connected to device X, each device may be statically assigned 1 Mbit / s of b...
