Abstract: The technologies described herein are generally directed toward managing signal traffic in a wireless network. Example operations can include receiving, for a group of cells, a control channel utilization value for a control channel and a data channel utilization value for a data channel. The operations can further include generating, based on the control channel utilization value and a threshold, for a first cell of the group of cells, a channel allocation that can increase the balance of use of control channel resources and data channel resources for the first cell, and configuring the first cell of the group of cells to allocate control channel resources and data channel resources of the first cell based on the channel allocation.

Abstract: In modern networks, frequent handovers (e.g., ping-pong) from one AP device to another is a situation that can lead to increased latency, excessive resource utilization, poor quality of service, or radio link failure (RLF). Conventional networks employ mobility robustness optimization (MRO) procedures to balance tradeoffs between setting low thresholds before initiating a handover procedure, thereby increasing the likelihood of ping-pong issues, and setting those thresholds to higher values, thereby increasing the likelihood of RLF. Conventional MRO procedures are tailored to terrestrial-only networks and furthermore merely react to existing issues. Hybrid networks, having both terrestrial and aerial AP devices often witness ping-pong issues and may be implemented with urgency not conducive to using MRO procedures. An architecture is presented that can predict and mitigate ping-pong and other issues in connection with hybrid networks before those issues occur.

Abstract: Aspects of the subject disclosure may include, for example, obtaining a first E-UTRAN cell global identifier (ECGI) associated with an aerial base station (ABS), determining a location of the ABS, and determining that a terrestrial base station (TBS) is within a distance threshold of the location of the ABS. Further embodiments include providing the first ECGI of the ABS to the TBS, and providing instructions to the TBS to indicate to each terrestrial communication devices (TCDs) communicatively coupled to the TBS to add a cell individual offset (CIO) factor to a first signal strength associated with a first signal received from the ABS. The TBS provides instructions to each of the TCDs to add a CIO factor to the first signal strength associated with the first signal received from the ABS. The second instructions includes the first ECGI associated with the ABS. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, deploying UAVs to a geographic area based on a need to offload traffic from a terrestrial base station, instructing the base station to enforce a UE served by the base station to determine a DoA of a received pilot signal emitted from each neighboring cell and to provide determined DoAs in a measurement report to the base station, obtaining the report from the base station, wherein the report includes DoA information for a plurality of neighboring cells, analyzing the DoA information to determine, for each neighboring cell of the plurality of neighboring cells, a probability of that neighboring cell being an aerial cell, resulting in determined probabilities, and controlling an ability of the base station to perform a handover of the UE to one or more of the plurality of neighboring cells based on the probabilities. Other embodiments are disclosed.

Abstract: An enhanced automatic neighbor relation (“ANR”) function can estimate a plurality of terrestrial cells within a coverage area of an aerial cell. The enhanced ANR function can monitor an exchange of a serving cell unique identifier sent to a target cell and a target cell unique identifier sent to a serving cell. The enhanced ANR function can determine a serving cell type and a target cell type, wherein the serving cell type and the target cell type identify the serving cell and the target cell, respectively, as either a terrestrial cell type or an aerial cell type. The enhanced ANR function can then determine whether a serving cell neighbor relation table (“NRT”) associated with the serving cell, a target cell NRT associated with the target cell, or both would be compromised if a corresponding NR is added into the serving cell NRT and the target cell NRT.

Abstract: The technologies described herein are generally directed to providing, based on a paging message, radio resources to facilitate a transition to active mode by idle user equipment in a fifth generation (5G) network or other next generation networks. An example method can include identifying an idle mode activation message. The method can further include, based on the activation message, predicting that the user device is going to request an active connection. Further, the method can include prioritizing allocation of antenna resources to the user device over different user devices in an idle state, based on a prediction that the user device will transition to an active state before the different user devices. Further, the method can include, based on the prioritizing, directing a base station to cause a beamformed signal to a predicted location of the user device to accept the active connection.

Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system detects user equipment (UE) in communication with a network via a serving cell of the network; the network is configured to facilitate communications by one or more terrestrial UEs and one or more aerial UEs. The system monitors messages from an aerial UE regarding detection of a cell other than the serving cell, and receives information from the aerial UE regarding the detected cell. The method further includes analyzing the information to estimate a first quantity associated with the detected cell location relative to the serving cell and a second quantity associated with a power received at the aerial UE from the detected cell. The method also includes determining, based on the analyzing, whether the aerial UE is an unauthorized aerial UE. Other embodiments are disclosed.

Abstract: The disclosed technology is directed towards improving system usage of a communication network with respect to on-demand system information delivery for certain user equipment devices. When a first user equipment requests on-demand delivery of other system information block data (e.g., SIB2, SIB3, and so on) from a base station, a second device, and possibly other devices, can wait to receive the other system information block data via a broadcast response to the request. Configuration data can indicate that a user equipment device is to operate in the requesting mode or the non-requesting mode. While operating in the non-requesting mode, a device can request the data if not timely received. A device can change modes based on condition data, e.g., QoS of an application, remaining battery power and the like. The disclosed technology can conserve both user equipment resources and network resources.
