Wireless roaming with dedicated backhaul
First Claim
1. A method for connecting a subscriber station with its operator using a wireless base station belonging to a different operator, comprising:
- establishing a wireless connection between (i) a wireless base station belonging to a first operator and (ii) at least one subscriber station associated with a second operator, using wireless spectrum belonging to the first operator;
opening a dedicated backhaul channel between the wireless base station and a second core network data source belonging to the second operator, wherein said dedicated backhaul channel is used substantially solely for communicating data sets between the second operator and the at least one subscriber station;
communicating data sets between the second core network data source and the at least one subscriber station, via (i) the dedicated backhaul channel and (ii) the wireless base station using the wireless spectrum;
opening a general backhaul channel between the wireless base station and a first core network data source belonging to the first operator, prior to opening the dedicated backhaul channel, wherein said general backhaul channel is used substantially solely for communicating data sets between the first operator and subscriber stations associated with the first operator; and
communicating data sets between the first core network data source belonging to the first operator and the subscriber stations associated with the first operator, via (i) the general backhaul channel and (ii) the wireless base station using the wireless spectrum, substantially concurrently with communicating data sets between the second core network data source belonging to the second operator and the at least one subscriber station associated with the second operator;
thereby creating a traffic separation at backhaul level between (i) data sets communicated between the first operator and its subscriber stations, and (ii) data sets communicated between the second operator and its subscriber stations;
wherein both subscriber stations associated with the first operator and subscriber stations associated with the second operator are wirelessly connected to the wireless base station, via a single radio access network created by the wireless base station using the wireless spectrum, thereby creating a traffic union at the radio access network between (i) data sets communicated between the first operator and its subscriber stations, and (ii) data sets communicated between the second operator and its subscriber stations.

Abstract
Systems and method are presented for a wireless Base Station (BS) of a host Operator to allow access to its Radio Access Network (RAN) by both Subscriber Stations associated with the host Operator and Subscriber Stations associated with other Operators, in which the first set of Subscriber Stations are connected by a general backhaul channel to the host Operator'"'"'s Core Network data source, and the second set of Subscriber Station are connected by dedicated backhaul channels to Core Network data sources of the other Operators. In this manner, the host Operator provides partial roaming to the second set of Subscriber Stations, which use the host Operators RAN and wireless BS, but not the host Operator'"'"'s network infrastructure.

8. A method for connecting a subscriber station with its operator using a wireless base station belonging to a different operator, comprising:
-
establishing a wireless connection between (i) a wireless base station belonging to a first operator and (ii) at least one subscriber station associated with a second operator, using wireless spectrum belonging to the first operator; opening a dedicated backhaul channel between the wireless base station and a second core network data source belonging to the second operator, wherein said dedicated backhaul channel is used substantially solely for communicating data sets between the second operator and the at least one subscriber station; communicating data sets between the second core network data source and the at least one subscriber station, via (i) the dedicated backhaul channel and (ii) the wireless base station using the wireless spectrum; opening a general backhaul channel between the wireless base station and a first core network data source belonging to the first operator, prior to opening the dedicated backhaul channel, wherein said general backhaul channel is used substantially solely for communicating data sets between the first operator and subscriber stations associated with the first operator; communicating data sets between the first core network data source belonging to the first operator and the subscriber stations associated with the first operator, via (i) the general backhaul channel and (ii) the wireless base station using the wireless spectrum, substantially concurrently with communicating data sets between the second core network data source belonging to the second operator and the at least one subscriber station associated with the second operator;
thereby creating a traffic separation at backhaul level between (i) data sets communicated between the first operator and its subscriber stations, and (ii) data sets communicated between the second operator and its subscriber stations; andeliminating a need of the subscriber stations associated with the second operator to use the first core network data source belonging to the first operator and core network data services belonging to the first operator, by opening and using said dedicated backhaul channel, thereby facilitating partial roaming. - View Dependent Claims (9, 10, 11, 12, 13, 14)
