Radio Access Network Sharing
First Claim
1. A method of sharing radio resources between a first cell of a first cellular network and a second cell of a second cellular network, the first and second cells each transmitting using a respective carrier of a different frequency and each cell using a respective scheduler to allocate transmissions to a respective plurality of radio resources, the method comprising:
- identifying a transmission for a user attached to the first cell that is available for radio resource allocation by the scheduler of the first cell, where the transmission could be made over the second carrier; and
interfacing between the scheduler of the first cell and the scheduler of the second cell, so as to allocate radio resources for use by the second cell to the transmission for the user attached to the first cell.

Abstract
The present invention relates to wireless systems, and in particular provides a method of sharing radio resources between a first cell of a first cellular network and a second cell of a second cellular network. Each cell transmits using a respective carrier of a different frequency and each cell uses a respective scheduler to allocate transmissions to a respective plurality of radio resources. The method comprises identifying a transmission for a user attached to the first cell that is available for radio resource allocation by the scheduler of the first cell, where the transmission could be made over the second carrier; and interfacing between the scheduler of the first cell and the scheduler of the second cell, so as to allocate radio resources for use by the second cell to the transmission for the user attached to the first cell.

15. An interfacing system for cellular networks, comprising:
-
a first cell of a first cellular network, configured to transmit using a carrier of a first frequency and having a first scheduler to allocate transmissions to a first plurality of radio resources; a second cell of a second cellular network, configured to transmit using a carrier of a second frequency, different from the first frequency and having a second scheduler to allocate transmissions to a second plurality of radio resources; and a broker, coupled between the first and second schedulers and configured to identify a transmission for a user attached to the first cell that is available for radio resource allocation by the scheduler of the first cell, where the transmission could be made over the second carrier, and further configured to interface between the first and second schedulers, so as to allocate radio resources for use by the second cell to the transmission for the user attached to the first cell.
