The system obtains KPIs of the production RAN of the network and capabilities of multiple UEs interacting with the test RAN. The system creates a test case based on the KPIs and the capabilities of the multiple UEs interacting with the test RAN by: adjusting a type of traffic associated with the test RAN, adjusting traffic characteristics, and adjusting the capabilities of the multiple UEs interacting with the test RAN. The system runs a simulation of the test case interacting with the test RAN to obtain simulation KPIs. The system determines whether the simulation KPIs correspond to the KPIs associated with the production RAN. Upon determining that the simulation KPIs correspond to the KPIs of the production RAN, the system stores the test case in a database. Upon determining that the simulation KPIs do not correspond to the KPIs of the production RAN, the system adjusts the test case.

Generating a test case associated with a test radio access network (RAN) based on key performance indicators associated with a production ran of a wireless telecommunication network

The system scans a RAN associated with a wireless telecommunication network to obtain an indication of a hardware status and a software status associated with the RAN. The system determines whether there is an update to the hardware or software status associated with the RAN. Upon determining there is the update, the system obtains from a first database an indication of a remote radio head configured to test the update. Based on the indication of the remote radio head, the system obtains from a second database multiple UEs configured to test the update. The system tests the update by causing the remote radio head to send a communication to a UE among the multiple UEs. The system obtains logs associated with the communication and, based on the logs, determines whether the update passes the tests.

Systems and methods are provided for dynamically modifying beamforming weights based on MU-MIMO user device pairings. A quantity of MU-MIMO user device pairings served by a node is determined. Based on a maximum quantity of potential MU-MIMO user device pairings for the node, it is determined that a quantity of the MU-MIMO user device pairings for the node is below a threshold. Because the quantity of the MU-MIMO user device pairings is below the threshold, beamforming weights are modified to widen a vertical main lobe to increase the quantity of MU-MIMO user device pairings.

Dedicating antenna elements to specific wireless devices by identifying specific wireless devices that meet a set of criteria, such as wireless devices using a certain application type that is associated with a bandwidth, and respectively dedicating a separate portion of antenna elements for communicating with each specific wireless device. The separate portion of antenna elements is selected based on being configured to utilize a bandwidth that meets a threshold bandwidth or matches the bandwidth associated with the application type.

A method and system for controlling application of split-uplink mode in a wireless communication system including an access node. In an example implementation, a method includes determining a first count defining how many user equipment devices (UEs) are connected with the access node and do not support a split-uplink-mode operation in which uplink user-plane data flow is split between air-interface transmission to the access node and air-interface transmission to another access node. Further, the method includes determining a second count defining how many UEs are connected with the access node as part of dual connectivity and support the split-uplink-mode operation. And the method includes, based on the first count and the second count, controlling whether the access node will allow the split-uplink-mode operation, such as whether the access node will allow new activation of the split-uplink-mode operation.

A method is provided for dynamically modifying a buffer in a network deploying multiple carriers, wherein multiple wireless devices communicate over the network. The wireless devices run applications, each application belonging to an application category. The method includes identifying the application category for a selected wireless device communicating over the network, wherein a first application category requires at least one of high throughput and low latency. The method additionally includes reducing a size of the buffer when the application category is the first application category, thereby initiating carrier aggregation for the selected wireless device.

Dedicating antenna elements to specific wireless devices by identifying specific wireless devices that meet a set of criteria, such as relay nodes, stationary wireless devices, data-only wireless devices, and respectively dedicating a separate portion of antenna elements for communicating with each specific wireless device. The separate portion of antenna elements is selected based on being configured to utilize a bandwidth that meets a threshold bandwidth, such as a 40 MHz bandwidth offered in 5G communications.

A system for dynamically modifying a buffer in a network deploying multiple carriers is provided. Each carrier operating over the network utilizes a radio access technology (RAT). The system includes a network load monitoring processor that measures a network load on carriers using a first RAT to produce a measured value and a buffer management processor that receives the measured value, performs a comparison of the measured value with a predetermined value, and dynamically modifies a size of the buffer when the measured value exceeds the predetermined value.

A method and system for controlling connectivity of a user equipment device (UE). When a UE is served with dual connectivity by a first access node over a first connection in accordance with a first radio access technology (RAT) and a second access node over a second connection in accordance with a second RAT, initiation of a voice call for the UE will be detected. And in response to at least detecting the initiation of the voice call for the UE, the first access node will invoke transition of the UE from being served with the dual connectivity over the first connection and the second connection to instead being served with standalone connectivity over the first connection.

Systems, methods, and processing nodes for selecting a backhaul carrier for a relay node including instructing the relay node to attempt to attach to a guard band associated with a carrier that shares a characteristic of the preferred backhaul carrier. The characteristic can include a channel size threshold or a threshold frequency. A numerology of a communication channel within the guard band may be adjusted to enable the relay node to communicate with a donor access node using the guard band.

A source wireless access node serves User Equipment (UEs) over a Three-Dimensional (3D) Multiple Input Multiple Output (MIMO) antenna array and over a Two-Dimensional (2D) MIMO antenna array. The source wireless access node wirelessly exchanges user data with the UEs over the 3D MIMO antenna array. The source wireless access node detects a loss-of-synchronization. The source wireless access node detects an interference condition at neighbor wireless access nodes. When the interference condition at the neighbor wireless access nodes and the loss-of-synchronization at the source wireless access node occur simultaneously, the source wireless access node network disables the 3D MIMO antenna array and wirelessly exchanges additional user data with the UEs over the 2D MIMO antenna array. When the neighbor interference condition or the loss-of-synchronization terminate, the source wireless access node enables and uses the 3D MIMO antenna array.

Embodiments disclosed herein describe systems, methods, and processing nodes for traffic management in wireless networks based on performing correlations between radio network attributes and wireless device attributes, and generating updated network parameters based on the correlation. Correlations between radio network attributes and wireless device attributes can yield commonalities or patterns based on a frequency band, a site, or a market. Based on the commonalities or patterns, network parameters such as cell reselection priority, allocation of resources, maximum traffic per frequency band, etc. can be calculated and deployed to various network elements such as control nodes, access nodes, wireless devices, etc. The deployment results in an optimal traffic distribution across each frequency band, such that the available spectrum is utilized efficiently and per-user throughput is maximized for all users of the wireless network.
