Abstract
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.
Claims40
A method comprising:
- receiving, from a mobile data transmitter traveling along a pre-determined route, a plurality of traffic loads in a current base station of a plurality of base stations along the pre-determined route;
- 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;
- 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
- forwarding the predicted traffic load data and the estimated time of hand-in to the future serving base station along the pre-determined route.
3 more elements
A method for transmitting wireless traffic from a mobile relay node to a base station, the method comprising:
- receiving, in a mobile relay node coupled to a vehicle of a rail transport system, a first plurality of data flows from a plurality of mobile computing devices being transported by the vehicle;
- aggregating the first plurality of data flows in the mobile relay node into an aggregated traffic load;
- and
- transmitting the aggregated traffic load from the mobile relay node to a base station,
- wherein information corresponding to a location of the vehicle and data corresponding to a traffic load comprising the first plurality of data flows is determined and disseminated to a plurality of communicatively coupled base stations along a pre-determined route.
2 more elements
An apparatus comprising:
- a mobile relay device provided on a vehicle operable to transport a plurality of passengers along a pre-determined route, the mobile relay device being operable to provide wireless communication services to the plurality of passengers,
- wherein information corresponding to a location of the mobile relay device and data corresponding to a traffic load comprising the wireless communication services provided by the mobile relay device is determined, and used to predict a time of hand-in and a predicted traffic load at the time of hand-in for a plurality of base stations communicatively coupled to the current base station along the pre-determined route,
- further wherein the time of hand-in and the predicted traffic load are disseminated to the plurality of base stations.
