Abstract: The described technology is generally directed towards a frequency-aware cellular communication network. A mobile device, or a radio access network (RAN) device at a base station in communication with the mobile device, can proactively notify a core network device regarding changes of a frequency band used for communications between the mobile device and the base station. The core network can use received notifications to adjust service provided to the mobile device.

Abstract: Control parameters can be used to enable or disable new radios (NR) of mobile devices and preserve battery life. For example, the control parameters can comprise a scan timer and a sleep timer. A mobile device can decode a network message, turn on an NR, and enable the scan timer. If an NR cell is available, the mobile device can enter LTE-NR dual connectivity mode in response to the network message. Conversely, when the scan timer expires, the mobile device can turn off the NR radio, and enable the sleep timer to preserve the mobile device battery. When the sleep timer expires, the mobile device can turn on the NR radio and enable the scan timer.

Abstract: An indicator (e.g., “5G+” or “5G”) displayed on a mobile device is based on whether the mobile device is connected in or (if idle) has the potential of connecting in a high channel bandwidth frequency band (e.g., n77 or mmWave). An accurate indication is displayed when the mobile device is connected, or when idle and the aggregated bandwidth is not directly known, such as when anchored to a lower bandwidth cell. When in idle mode, the mobile device can maintain cell identifiers (“fingerprints”) and determine a location estimated to be within a high bandwidth cell, to thereby determine potential high bandwidth operation (e.g., and display 5G+) when connected. When in the idle mode, the mobile device can evaluate neighbor cells including if within a high channel bandwidth cell’s coverage to decide whether to select “5G+” or “5G” for display to indicate the potential high bandwidth operation (or not) when connected.

Abstract: A method includes determining a quality of service class identifier (QCI) level for an application running on a user device, selecting a connected mode discontinuous reception (CDRX) profile based on the QCI level, and transmitting the CDRX profile to the user device to be used when running the application. The QCI level may be indicative of delay sensitivity of the application and the CDRX profile may be selected based on the delay sensitivity of the application.

Abstract: Aspects of the subject disclosure may include, for example, detecting initiation of a service associated with a UE, where the service comprises an OTT voice/video call, facilitating, for the service, activation of an end-to-end network slice between a core network and the UE, detecting a RAT switch determination for the UE, where the RAT switch determination relates to communicative coupling of the UE with a second network node, and where the second network node is associated with a second RAT different from the first RAT, responsive to the detecting the RAT switch determination, determining whether the service is ongoing over the end-to-end network slice, and, based on a determination that the service is ongoing over the end-to-end network slice, preventing the UE from communicatively coupling with the second network node until the service is determined to be completed or until the end-to-end network slice is released. Other embodiments are disclosed.

Abstract: This disclosure proposes a system to manage radio frequency (RF) interferences towards earth stations to solve needs of network providers. For example, user a user equipment that is close to an earth station can cause signal interference with the earth station as the user equipment is communicating with a base station. However, if the base station shares earth station location information with the user equipment, the user equipment can adjust its frequency and/or reduce its signal power to mitigate interference with the earth station. Alternatively, or in addition to, the base station can adjust its signal strength, and/or terminate a signal or resource that it is sending to the user equipment to prevent signal interference with the earth station.

Abstract: Dynamic spectrum sharing (DSS) deployments are described, in which smaller-bandwidth frequency bands (e.g., of fourth generation long term evolution, or 4G LTE) are combined into larger total bandwidth spectrum which overlaps the (larger bandwidth) spectrum of a new radio frequency band. For example, two ten megahertz LTE frequency bands can be combined to provide twenty megahertz total spectrum, which can overlap with twenty megahertz 5G spectrum for use in LTE/5G DSS. The LTE downlink subframes of each LTE frequency band are time and frame structure aligned with each other and with the new radio frequency band's downlink subframes. For uplink communications, the physical resource blocks (PRBs) are scheduled to leverage new radio's extra available PRBs. Such enhanced DSS facilitates setting up a single DSS carrier (instead of multiple traditional DSS carriers), which provides relatively better downlink and uplink throughput, less layer management and other similar benefits.

Abstract: Event triggered network parameter manipulation can include detecting a trigger to collect data associated with a connection between a user equipment and a cellular network; triggering delivery of a radio resource control message to the user equipment by the cellular network; and receiving, from the user equipment, a report that can include operational data associated with the user equipment. Data from the cellular network can be obtained. The data can include the report and operational data associated with the cellular network. The operational data associated with the cellular network can include connection parameters associated with the connection between the user equipment and the cellular network. The data can be analyzed to determine one of the connection parameters that is to be manipulated, and a command that instructs a recipient of the command to manipulate the one of the connection parameters can be issued.
