Patent ID: 7986971

Claim:
A method, comprising: connecting at least two different core networks to one radio access network; sharing a base station of the radio access network between that at least two different core networks by using a first frequency to establish a first cell at the base station for one or the at least two different core networks and using a second frequency to establish a second cell at the base station for another one of the at least two different core networks, wherein a cellular radio network includes a radio access network and a core network, the radio access network comprising at least a radio network controller and a plurality of base stations; sharing a radio network controller of the radio access network between the at least two different core networks; and creating an allocation of traffic between the base station and the at least two different core networks using the shared radio network controller, wherein the allocation comprises a determination of first traffic for the first cell established at the base station to be associated with a first core network of the at least two different core networks, and wherein the allocation further comprises a determination of second traffic for the second cell established at the base station to be associated with a second core network of the at least two different core networks.
