摘要： A method for assigning downlink transmit power levels to radio nodes (RNs) in a small cell radio access network (RAN) includes assigning initial power levels to the RNs. For each cell, first events are counted indicating that UEs receiving a signal from their serving cells with a signal strength below a specified value have entered a coverage hole. For each cell, second events are counted indicating that UEs have re-established a previous connection on one of the cells. For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.

摘要： A method for upgrading an access controller that controls and coordinates a plurality of radio nodes (RNs) each associated with a cell in a cluster of cells belonging to a radio access network includes initializing a new access controller. The new access controller is to replace a current access controller currently controlling and coordinating the plurality of RNs cell in the cluster. A most lightly loaded one of the plurality of RNs is identified. All UEs currently attached to the identified RN is caused to be handed off to a neighboring cell in the cluster. After all the UEs have been handed-off from the identified RN, the identified RN is rebooted so that it is being controlled and coordinated by the new access controller. The steps of causing the UEs to be handed-off and rebooting the identified RN are repeated for a second one of the plurality of RNs.

摘要： A method for assigning a percentage of a CSAT time cycle to each radio node (RN) in a plurality of RNs that belong to a small cell radio access network (RAN) having a central controller includes: (i) for each time cycle period during which the RNs share a channel with one or more nodes that employ a different radio access technology (RAT), assigning a default occupancy percentage of the time cycles to each of the RNs; (ii) determining if the default occupancy percentage is able to be increased without violating one or more co-existence principles pre-established for the RAT employed by the RNs in the RAN and the different RAT; (iii) increasing the occupancy percentage of the first RN if it is determined that the default occupancy percentage is able to be increased without violating the co-existence principles; and (iv) sequentially repeating (ii)-(iii) for each remaining RN in the RAN.

摘要： A method of coordinating a plurality of radio access networks (RANs) includes aggregating, with a gateway, communications interfaces between a plurality of RANs and a packet core network through the gateway. A plurality of radio nodes (RNs) in each of the RANs is communicatively coupled to the gateway and to user equipment (UE) devices associated with the RNs in each of the RANs. The gateway also controls and coordinates mobility of the UE devices within and among the RANs. In addition, the gateway acts as a virtual enhanced NodeB (eNB) to the packet core network, thereby hiding the aggregated communications interfaces from the packet core network.

摘要： Systems and methods disclosed detect significant changes in the RN topology after an E-RAN system has been installed and provisioned. If a significant change is detected, the operator is notified through an alarm, and the operator can take action to correct it. For example, an RN whose location was moved may be disabled. Alternatively, the movement operation may be approved and the alarm cleared so long as the operation falls within certain approved guidelines or categories, e.g., is appropriately reported and a new location noted.

摘要： Discovery of a neighbor radio access system by a user mobile communications device serviced in a radio access network (RAN) for reporting to a serving system in the RAN. User mobile communications device serviced by a RAN is configured to scan one or more frequency ranges (e.g., bands) to discover other neighbor radio access systems. This is opposed to, for example, the user mobile communications device only searching for transmitted communications signals at specific center frequency (e.g., an EARFCN). There may be other radio access systems that operate neighbor cells and in other frequency bands in proximity the RAN serving the user mobile communications device. Discovered neighboring radio access systems can be reported by the user mobile communications device to its serving RAN in a measurement report, which can then be used by the serving RAN for other functionalities, such as trigger handovers of user mobile communications device for example.

摘要： Systems and methods are disclosed that provide a closed loop power control system including adaptively adjusting the desired target SINR over time so as to ultimately achieve a feasible SINR. In one implementation, a method is provided of optimizing uplink closed loop power control in a RAN in which one or more base stations each service a plurality of mobile stations, including: determining a power level for each mobile station for its respective uplink transmissions, including measuring a current achieved SINR for each mobile station; and for each mobile station, adjusting the power level to be sufficiently high to meet desired transmission characteristics but not so high as to cause unnecessary interference with transmissions from other mobile stations, by adjusting a desired target SINR based on factors selected from the following: current and prior achieved SINRs, current and prior interference measurements, and current and prior transmission power control commands.

摘要： Systems and methods are provided for resolving Primary Scrambling Code (PSC) ambiguity. A radio link having the same PSC as that reported by user equipment (UE) may be created on some or all internal cells which are chosen based on radio frequency (RF) proximity to a serving cell of the UE or one or more iterations of a PSC resolution set selection process. If the UE is reporting the PSC of one of these cells, the UE and a Node Bs will be able to successfully complete a synchronization procedure to add one of the radio links to the UE's active set, while any remaining created radio links can be deleted. After a certain number of successful radio link additions, the combination of the PSC and active set may be considered to be resolved, therefore, negating a need to resolve the PSC in subsequent soft handover requests.
