Procedures and devices to improve timely traffic flow in integrated multi-RAT heterogeneous networks

摘要

A method for distributing, by means of an eNodeB (110, 130) serving a cell (120), user equipment (170, 180) of the cell (120) among multiple radio access technologies integrated in the cell (120) , the procedure comprising: planning (300) transmissions, during a measurement period, by at least one of the multiple radio access technologies; estimate (310), depending on the transmissions, an opportune traffic flow for the user equipment (170, 180) of the cell (120), the opportune traffic flow being a measure of the amount of data that reaches a destination before reaching a delay threshold and at a bit rate greater than or equal to a target bit rate; and depending on the estimated timely traffic flow for the user equipment (170, 180) of the cell (120), assign user equipment (170, 180) of the cell (340) to a wireless interface of one of the multiple Cell radio access technologies (120) to maximize the flow of timely traffic.
