Abstract

Systems are provided for managing a small cell telecommunication system servicing multiple network operators. In one aspect, a small cell telecommunication system can include management sub-system including a controller, multiple baseband processing units in communication with the controller, a transport module, and multiple remote antenna units. The controller can communicate with multiple core networks. Each core network is operated by a separate network operator for providing telecommunication services to terminal devices. Each of the baseband processing units can process data plane data and control plane data from at least one respective core network. The transport module can communicate signals between the baseband processing units and the remote antenna units of the small cell network. The management sub-system can provide a respective amount of capacity via the small cell network for each core network based on a respective subset of the baseband processing units assigned to the core network.
