1. A system for resource sharing between at least a first cellular radio access network (RAN) and a second cellular RAN sharing a common carrier, the system comprising:
at least one base station, the at least one base station configured to operate a first RAN network and a second RAN network using at least one common carrier;
a resource manager corresponding to the at least one base station, the resource manager configured to,
determine whether to allocate at least one future slot of a radio frame of the common carrier as a first RAN slot or a second RAN slot based on,
received first RAN resource utilization information and received second RAN resource utilization information corresponding to a current slot of the radio frame of the common carrier, or
active connection information corresponding to active first RAN connections served by the at least one base station and active second RAN connections served by the at least one base station,
generate first RAN resource allocation information and second RAN resource allocation information corresponding to the at least one future slot based on results of the determining, and
transmit the first RAN resource allocation information and the second RAN resource allocation information to at least one RAN scheduler corresponding to the at least one base station; and
a connection manager corresponding to the at least one base station, the connection manager configured to determine whether to transmit a connection mode instruction to at least one first RAN user equipment (UE) device connected to the first RAN network to establish a connection to the second RAN network based on an amount of data that has been transmitted to or by the at least one first RAN UE device, and an overhead associated with connecting the at least one first RAN UE device to de second RAN network.
