  • Publication number: 20210329458
    Abstract: Aspects of the subject disclosure may include, for example, obtaining a preliminary transmission received from a first wireless access terminal of a wireless network, at a mobile terminal, wherein the obtaining of the preliminary transmission occurs before a successful completion of an attachment process between the mobile terminal and the first wireless access terminal, and wherein access to a network resource by the mobile terminal via the wireless network requires a successful completion of the attachment process. A physical relationship is determined between the mobile terminal and the first wireless access terminal according to the preliminary transmission, resulting in a determined physical relationship. The determined physical relationship is compared to a predetermined threshold value to obtain a comparison result and successful completion of the attachment process is prevented based on the comparison result indicating a suspect condition. Other embodiments are disclosed.

  • Patent number: 11115931
    Abstract: Various embodiments disclosed herein provide for facilitating uplink interference avoidance. According an embodiment, a system can comprise receiving a request to adjust an uplink power limit of a first communication device that is generating an uplink interference above a threshold and a power adjustment value employable to adjust the uplink power limit of the first communication device. The system can further facilitate identifying a packet flow in an uplink communication with the first communication device, wherein use of the packet flow results in generating of the uplink interference above the threshold. The system can further facilitate determining whether the uplink power limit of the first communication device is able to be adjusted based on a quality of service allocated to the packet flow. The system can further facilitate transmitting a message to update the uplink power limit of the first communication device using the power adjustment value.

  • Patent number: 11051222
    Abstract: Beamforming techniques can improve base station transmission power and user equipment (UE) sensitivity reception. For example, beamforming can create a narrow beam, which can concentrate signal power in a much smaller region. Combined with base station (gNB) requests and UE location data, an accurate beam can be generated to cover a desired area. 5G base station broadcasts can utilize a globally unique cell identifier (e.g., physical cell identifier), and a locally unique cell identifier (e.g., new radio cell global identifier) to facilitate beamforming and mitigate handover failure.

  • Patent number: 10531315
    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.

  • Patent number: 10447713
    Abstract: Concepts and technologies disclosed herein are directed to internet traffic classification via time-frequency analysis. According to one aspect of the concepts and technologies disclosed herein, a security classification scheme can be implemented to identify potentially malicious activities from normal internet traffic. The security classification scheme can exploit the distinctive characteristics of different types of traffic in both frequency domain and time domain to identify four different cases. Due to the separation of different types of traffic, the security classification scheme can lower the false alarm rate and improve network security. The security classification scheme can utilize a recursive discrete Fourier transform (“DFT”) implementation to enhance computational efficiency.
