    Abstract: Passive collection of neighbor base station configuration information through handover messages is provided. In one embodiment, a base station comprises: a processor coupled to a memory, the base station coupled to a core network for a wireless network operator, the base station radiates downlink RF signals to at least one UE and receives uplink RF signals from the UE. The processor implements: a UE handover function that receives and processes a handover request message associated with a UE transferring to the cell from a neighboring cell; and a handover request parser that evaluates information elements in the handover request message to extract neighbor information. The handover request parser stores the extracted neighbor information as a set of neighbor information in the memory; and wherein the processor is configured to adjust operation of the base station based on the set of neighbor information stored in the memory.

    Abstract: A system for load-testing a cloud radio access network (C-RAN) is provided. The system includes at least one radio point (RP), each being configured to exchange radio frequency (RF) signals with at least one user equipment (UE). The system also includes a baseband controller communicatively coupled to the at least one RP via a front-haul ETHERNET network. The front-haul ETHERNET network includes at least one switch; and a testing device that is time-synchronized to the baseband controller and the at least one RP. The testing device is configured to receive at least one packet from each of the at least one RP. The testing device is also configured to replicate each of at least some of the received packets to produce a respective replicated packet. The testing device is also configured to transmit at least one replicated packet to the baseband controller.

    Abstract: A distributed radio access network (RAN) includes a plurality of remote units (RUs), each being configured to exchange RF signals with at least one UE. The distributed RAN also includes a central unit communicatively coupled to the plurality of RUs via a fronthaul and/or midhaul network comprising one or more ethernet switches. The distributed RAN also includes at least one processor configured to receive diagnostic information relating at least to processing performed for at least two layers of a network and/or air interface implemented by the distributed RAN; identify a system performance problem based on the diagnostic information; search for a cause of the system performance problem using at least a portion of the diagnostic information; and when the cause of the system performance problem is identified using the at least a portion of the diagnostic information, determine at least one action to correct, limit, or circumvent the system performance problem.

    Abstract: A distributed radio access network (RAN) includes a plurality of radio points (RPs), each being configured to exchange radio frequency (RF) signals with at least one user equipment (UE). The distributed RAN also includes a baseband controller communicatively coupled to the plurality of RPs via a fronthaul network. The baseband controller is configured to determine, for each of the plurality of RPs, a number of successfully received packets on the fronthaul network, for a wireless channel, during a measurement interval. The baseband controller is also configured to determine, for each of the plurality of RPs, a number of packet losses (reflecting dropped and/or delayed packets), for the wireless channel and during the measurement interval, based on the number of successfully received packets.
