A method and network node for determining a Radio Frequency (RF) propagation model for a coverage area from an image view of the coverage area. The method selects a coverage area for a transmission point of a transmitter and obtains an image view of the selected coverage area. The method further recognizes, from a plurality of morphology types, a morphology type for the selected coverage area from the obtained image view using a machine learning model; and determines a RF propagation model for the selected coverage area based on the recognized morphology type.

A system, method and non-transitory computer readable media for facilitating network connectivity in a split architecture fronthaul network () comprising a plurality of cells (-to--to-) and one or more BBU hubs (A,B), each hub comprising at least a BBU (-N,-M). An example cell allocation process (B,A) is configured to assign cells to the hubs sequentially, i.e., a hub must be completely full (e.g., with respect to certain predetermined capacity such as port utilization) before adding cells to any other hubs. Once a hub is full, the allocated cells are further assigned to the individual BBUs of the hub also sequentially (B). An optimal cell allocation map () is thereby obtained, which may be used in (re)configuring the connectivity between the cells (-to--to-) and the hubs/BBUs (-N,-M).

A system, method and non-transitory computer readable media for optimizing input data for an ML model associated with a communications network. In one implementation, example ML model(s) may be trained using a modified dataset obtained for a plurality of cellular aggregation units (CAUs) of the RAN infrastructure(s), wherein the modified dataset is derived from data collected for individual CAUs over a data collection period with respect to a plurality of KPI variables. The modified data set is optimized by replacement of null values of variables with corresponding modal values of the variables. The trained ML model may be used for predicting one or more KPIs based on a set of test data associated with the RAN infrastructure(s).

A baseband and method in a centralized radio access network (C-RAN) are described herein that are configured to dynamically select an 'X' number of neighboring basebands to be assigned to a co-ordination set of the baseband based at least in part on measurement reports received from a plurality of user equipments (UEs).

In a wireless communications network, the presence of a wireless local area network in a cell segment is determined. An identifier of the wireless local area network in the cell segment is sent to at least one mobile station in the cell segment to enable the at least one mobile station to hand off to the wireless local area network. Optionally, information identifying geographic boundaries of cell segments and the wireless local area network can be sent to the at least one mobile station.

Various embodiments provide for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.

A method and system provide a plurality of femto cells that are deployed within a macro cell of cellular network. The femto cells improve cellular service inside structures, such as residential and commercial structures. Femto base stations convert signals between an airlink-interface and core network to enable data communication between the mobile terminal and an access network to occur through the Internet and a public switched telephone network. The femto base stations are independent of each other and the macro cell. The method and system provide the femto base stations with interference awareness and mitigation techniques to minimize interference with the cellular network.

An Optimized Streetlight Operation (OSLO) system that utilizes a cellular network overlay to broadcast control commands issued by a centralized Streetlight Operation Center (SOC) to RF control modules mounted on each streetlight pole. The cellular network may be a CDMA network utilizing Short Message Service-Broadcast (SMS-B) messaging. When a Mobile Telephone Exchange/Mobile Switching Center (MTX/MSC) receives a SOC control command from the SOC, the MTX/MSC causes a plurality of BSs to broadcast the SOC command in the network operating area a defined number of times. Each RF control module that successfully receives the broadcast SOC control command, performs actions to control operation of the module's associated streetlight, and transmits a confirmation message to the module's serving BS indicating the SOC command was received. The modules are configured to stagger transmission of the confirmation messages over a period of time to reduce a peak load imposed on the cellular network.
