Abstract: A computer-implemented method for managing radio spectrum in a cellular network including periodically analyzing a local spectrum utilization data to determine spectrum use levels at the local base station. The method may include periodically receiving, at the local base station, neighbor spectrum utilization data from at least one neighbor base station in the cellular network. The neighbor spectrum utilization data is associated with spectrum use levels at the at least one neighbor base station. The method may include receiving a spectrum assignment request from a mobile computing device and, in response, determining a spectrum assignment for the mobile computing device based on at least one of the neighbor spectrum utilization data and local spectrum utilization data. The method may include transmitting the spectrum assignment to the mobile computing device.

Abstract: Systems and methods for maintaining and dynamically updating inactivity timers at a user equipment to detect a one-way audio or mute call to improve call experience are disclosed. The method enables the user equipment to perform a set of actions (e.g., enable, disable, drop call, don't drop call, etc.) when a one-way audio or mute call is detected. Values for the timer and/or action parameters can be dynamically determined and/or communicated to the user equipment by a telecommunications service provider based on one or more of the following factors: network health, network congestion, current events, type of call (e.g., emergency, non-emergency), type of customer (e.g., business, premium, residential, etc.), service-level agreement, and so on. Values for the timer and/or action parameters can be configurable based on a location.

Abstract: Systems and methods for controlling carrier aggregation (CA) are disclosed. The method includes determining a communication characteristic describing data communicated between, e.g., user equipment (UE) and a communication endpoint. The communication characteristic is used to generate a CA trigger that controls at a communication node a number or assignment of component carriers or communication slots used to communicate the data to/from the UE.

Abstract: Systems and methods are provided for performing channel estimation in a multiple input multiple output (MIMO) based cellular radio technology (e.g., 4G, 5G). Initially, the reference transmission receive power (RSRP) is reported for each antenna element, rather than as a single RSRP. This enables the base station to understand the channel condition for each MIMO transmission/reception. Using that understanding, the base station can determine the radio-frequency (RF) power level per antenna port to provide more enhanced transmission towards a specific UE, resulting in a better service experience. In other words, more accurate channel estimation based on actual RF conditions of a particular UE can be derived so the base station can tune to the actual need of the UE.

Abstract: Systems and methods are provided for dynamically adjusting a 4G LTE reference signal power level to match a 5G New Radio (NR) coverage footprint to avoid voice over 4G fallback failures for 5G subscribers. Initially, a subscriber making a voice call while in NR coverage may be directed to fall back to LTE in a process known as voice over evolved packet system fallback (VoEPSFB). If the LTE signal strength is worse due to non-optimal settings of the LTE reference signal, the subscriber experiences call setup failure. After the call setup failure, the UE transitions back to the gNodeB. Since the gNodeB knows the UE attempted to fall back to LTE (as well as how soon the UE transitioned back to the gNodeB), a notification is triggered that instructs the LTE base station to increase its reference signal power level.

Abstract: Systems may comprise a connectivity manager application operating on a User Equipment (UE) for optimal and secure performance of local applications and improving user experience by optimizing application performance (e.g., detecting data stall events). The systems may monitor incoming internet protocol (IP) packets for one or more applications operating on the UE. The connectivity manager application may detect a drop in a rate at which the IP packets are received over a period of time and determine to reregister and/or reattach to a different node within a network or at a new network.

Abstract: Processes and systems for identifying and removing non-functional Internet-of-Things (IoT) devices from a cellular network are discussed herein. In one example, a probability distribution function of a data profile transmitted by a type of IoT devices is generated. The probability distribution function may be chosen based on a known distribution such as a Gaussian, Bessel, or linear regressive model. The probability distribution function may be empirically generated by applying data received from IoT devices to a machine learning model using supervised or unsupervised learning. After generating the model representing the expected data profile of data received from a type or class IoT devices, data transmitted by the IoT devices may be applied to the model to determine whether the IoT devices are functional or non-functional. Non-functional IoT devices may be removed from the cellular network.

Abstract: Solutions for dynamically toggling physical downlink control channel (PDCCH) interleaving include: a base station receiving radio measurement reports from a user equipment (UE); based on at least the radio measurement reports, determining that radio reception by the UE meets a threshold; based on at least meeting the threshold, ceasing to interleave data on the PDCCH. The base station continues to monitor radio measurement reports from the UE, and based on at least the radio measurement reports indicating that radio reception by the UE meets a second threshold, resuming interleaving data transmitted on the PDCCH. In some examples, UEs are managed in broadcast groups (e.g., UEs within a common in a cell sector), and interleaving or ceasing interleaving is based on a determination of whether all UEs in the broadcast group are able to forego interleaving.

Abstract: The disclosed system defines multiple regions around a cell tower providing coverage to a UE. The multiple regions describe the location of the UE in relation to the cell tower. The multiple regions include a near region and a far region. The system sends a request to the UE to provide an indication of a distance between the UE and the cell tower. Based on the distance between the UE and the cell tower, the system categorizes the location of the UE in relation to the cell tower into one of the multiple regions. The system receives an indication of a problem in a communication between the UE and the wireless telecommunication network. Based on the one of the multiple regions into which the location of the UE is categorized, the system determines a likely source of the problem such as the UE, a radio network, or a core network.

Abstract: The technology described herein provides for optimizing communications, such as Real-time network services, by using multiple TCP ports. In embodiments, a user device sends a data packet using a first TCP port, determines that the data packet has not been received by a receiving device, and uses a second TCP port to re-send the data packet. In addition or alternatively, the user device can determine the availability of additional TCP ports for re-sending data if the user device determines that the data packet sent using the first TCP port has not been received. Through this technology, the user device will be able to alleviate the reduction in quality of or outright failure of its real-time network services.

Abstract: Techniques for setting up a communication session associated with Evolved Packet System Fallback (EPSFB) are described herein. A fifth generation telecommunications network can implement a server to determine that a user equipment (UE) is incapable of establishing a Voice over New Radio (VoNR) call due to a chipset or other technology used by the UE. The server can send a message (e.g., a SIP380 Alternative Service message) to the UE to cause the UE to begin fallback to another network without waiting for an instruction from a base station in a standardized call flow. The server can establish the communication session for the UE using fewer call flow steps than a number of steps used by a standardized call flow.

Abstract: Systems and methods are provided herein to perform edge computing in 4G and 5G cores based on application usage. Networks identify highly requested content at an access point and may use network data analytics functions to identify which content is popular in the area served by an access point. The highly requested content may be applications, webpages, or similar content. Once the highly requested content has been identified, tunneling to at least one application server to download the highly requested content occurs. The content may then be stored in a dynamically caching server near the access point. The network data analytics operations to identify highly requested content may be performed on a periodic basis, and content that no longer meets a predetermined threshold may be flushed from the dynamically caching server.

Abstract: Systems and methods are provided for communicating service type in a paging message for cellular communication (e.g., 4G, 5G). This enables the radio network and user equipment (UE) to be aware of the paging service type and prioritize the most critical signaling events. Initially, a service indication flag is received from one or more of: a radio resource control message from a UE of the one or more UEs; a S1-AP message from a Mobile Management Entity; or a Next Generation Application Protocol message from an Access and Mobility Management Function. Based on the service indication flag, a service type of a terminating service that is causing the UE to be paged is determined. Based on the determined service type, resources can be allocated for the UE.
