Forward traffic announcements for enhanced resource reservation in high speed mobile relays

摘要

The claimed subject matter pertains to the use of mobile relay nodes to serve users on high speed trains. In particular, this invention defines a framework that enables a base station of a cellular network to make accurate predictions of future traffic load, and take appropriate steps to serve this traffic, such as reserving sufficient air interface, backhaul, and processing resources.

主权项

1. A method of operating a current base station of a plurality of base stations along a pre-determined route, the method comprising:
receiving, by the current base station of the plurality of base stations, a plurality of traffic loads from a mobile data transmitter traveling along the pre-determined route, wherein the mobile data transmitter comprises a mobile relay node provided on a mass transit vehicle, the mass transit vehicle being operable to transport a plurality of passengers, wherein the plurality of traffic loads comprise data packets transmitted from a plurality of mobile computing devices operated by the plurality of passengers being transported by the mass transit vehicle; measuring the plurality of traffic loads to derive traffic load data corresponding to the plurality of traffic loads; estimating a time of hand-in of the mobile data transmitter to a future serving base station of the plurality of base stations along the pre-determined route based on an estimated location of the mobile data transmitter; before the mobile data transmitter enters a coverage area of the future serving base station, predicting an incoming traffic load corresponding to the hand-in of the mobile data transmitter to the future serving base station from the traffic load data; and before the mobile data transmitter enters the coverage area of the future serving base station, forwarding predicted traffic load data and the estimated time of hand-in to the future serving base station along the pre-determined route.
