摘要： This disclosure relates to automatically configuring a front-haul switched Ethernet network for a C-RAN. The topology of the front-haul switched Ethernet network is automatically discovered. One or more switches in the front-haul switched Ethernet network are automatically configured. The configuration of the one or more switches in the front-haul switched Ethernet network is automatically verified. The discovered topology can be automatically verified. Also, the discovered topology or the configuration of the front-haul switched Ethernet network can be automatically validated to check if it corresponds to a network design for the front-haul switched Ethernet network.

摘要： One embodiment is directed to a system comprising a plurality of controllers and a plurality of radio points that provide wireless service to user equipment. The system is configured to serve a plurality of logical cells. The system is configured so that each logical cell is served by a respective group of the radio points. The system is configured to associate each group of radio points with a respective one or more controllers in order for the respective one or more controllers to serve the respective logical cell associated with that group of radio points while associated therewith. The system is configured to use a protection scheme in which the respective group of radio points that serves each logical cell does not change in the event of a fail-over that causes the one or more controllers associated with that group of radio points to change.

摘要： One embodiment is directed to a multi-carrier radio point for use in a centralized radio access network (C-RAN). The multi-carrier radio point is configured so that the processing and hardware resources provided by the radio point can be associated with controllers of the C-RAN in a flexible manner. A single multi-carrier radio point can be used with multiple controllers to serve multiple cells, where the processing and hardware resources used for the multiple controllers need not be configured and used in the same way.

摘要： A cloud radio access network (C-RAN) includes a plurality of remote units (RUs), each with a wireless transceiver to exchange RF signals with at least one UE. The C-RAN also includes a central controller communicatively coupled to the plurality of RUs via a fronthaul comprising one or more ETHERNET switches. The central controller is communicatively coupled to an activation server via a backhaul network. The central controller also includes at least one processor configured to, following initial power up, establish a connection to the activation server indicated by activation server information pre-configured on the central controller. The at least one processor is also configured to receive a commissioning package, which includes commissioning information, from the activation server. The at least one processor is also configured to configure the central controller based on the commissioning information.
