Method and system for handling queues in communication networks, corresponding computer program product

摘要

In a communication network, a node receives from user equipment information on the length of a queue of information units to be transmitted to the node from the user equipment. The information, for possible use by the node in scheduling transmission of these information units from the user equipment, is in the form of quantized queue length information indicative of a lower bound and an upper bound for the queue length. Transmission of information units from the user equipment to the node is detected at the node, and an improved estimate of the queue length is produced by correcting the lower bound and the upper bound via subtraction of the number of the detected information units transmitted from the user equipment to the node.

主权项

1. A method of estimating, at a first point of a communication network, the length of a queue of information units to be transmitted to said first point from a second point in said network, comprising receiving at said first point from said second point, quantized queue length information, said quantized queue length information being indicative of a lower bound and an upper bound for said queue length, comprising:
detecting at said first point, transmission of information units from said second point to said first point; and producing an improved estimate of said queue length by correcting said lower bound and said upper bound via subtraction of the number of the detected information units transmitted from said second point to said first point.
