Shared backhaul link for multiple wireless systems
First Claim
1. A method for effectively utilizing a shared backhaul link connected to a wireless base station servicing a plurality of operators comprising first and second operators, said method comprising:
- receiving, by the wireless base station, from first and second core network data sources belonging to the first and second operators, first and second sets of data respectively, via the shared backhaul link connected to the wireless base station;
conveying wirelessly, by the wireless base station, the first and second sets of data, to first and second sets of subscriber stations associated with the first and second operators, at first and a second wireless data rates respectively; and
controlling the first wireless data rate such that the first and second sets of data received via the shared backhaul link together do not substantially exceed a predetermined backhaul data rate, andwherein the controlling is done by limiting the number of subscriber stations in the first set of subscriber stations.

Abstract
Systems and methods are presented for effectively utilizing a Backhaul link shared by two or more wireless system Operators, such that data rates from multiple Core Network data sources to the shared Backhaul link, and data rates from multiple sets of Subscriber Stations to the shared Backhaul link, are controlled so that a combined downlink rate substantially does not exceed a predetermined Backhaul data rate, and a combined uplink rate substantially does not exceed a predetermined Backhaul data rate, thereby preventing an overloading of the shared Backhaul link. Further, communication rates of different data sets within the downstream and upstream, respectively, are dynamically altered to provide best overall service within the downstream and upstream, respectively, while not overloading the shared Backhaul link.

5. A method for effectively sharing a backhaul link between at least two radio access networks belonging to different operators comprising first operator and second operators, said method comprising:
-
receiving, by a first radio access network belonging to the first operator, a first backhaul transmission intended for a first set of subscriber stations serviced by the first radio access network, via the shared backhaul link, wherein the shared backhaul link transports the first backhaul transmission together with at least a second backhaul transmission intended for a second set of subscriber stations serviced by a second radio access network; controlling the rate at which the first backhaul transmission is received, such that the first and second backhaul transmissions via the shared backhaul link together do not substantially exceed a predetermined backhaul data rate; and wherein the first backhaul transmission is transported from a first core network data source belonging to the first operator to the first radio access network using a first network tunnel passing through the shared backhaul link. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
