  • Publication number: 20220345203
    Abstract: Methods and systems for sharing aerial assets amongst terrestrial network operators. Embodiments enable sharing of aerial assets amongst the terrestrial network operators and facilitate on-demand deployment of the aerial cells to improve coverage and capacity of the terrestrial network operators. Embodiments allow sharing of aerial assets such as aerial cell mount, backhaul, an aerial RAN, and aerial spectrum using sharing architectures. Embodiments provide a managing entity for forecasting data traffic pertaining to the terrestrial network operators and optimizing the deployment of the aerial cells, based on the forecasted data traffic, for enabling strategic deployment of the aerial cells. Embodiments ensure that the resources of the aerial cells are effectively utilized and the number of aerial cells required for enhancing the capacity of the terrestrial network operators is minimized.

  • Publication number: 20220201699
    Abstract: Techniques are disclosed for increasing the sum spectral efficiency (SE) of cellular networks including Hybrid In Band Full Duplex (IBFD) cellular networks. These techniques include using various constraints to identify UEs that qualify to be included as part one or more frequency sharing groups. The qualification process may use, as one of the constraints, a distance between served UEs such that UEs that are too close to one another are disqualified. The UE frequency sharing groups may include at least two UEs that use the same shared frequency as an upload channel frequency one UE as the other UE uses for a downlink channel frequency. Techniques are also disclosed for the allocation of frequencies and to determine when the current groupings and/or allocated frequencies are invalid.

  • Patent number: 10129294
    Abstract: A method and a device are provided for categorizing a Stream Control Transmission Protocol (SCTP) receiver terminal (120) as a malicious SCTP receiver terminal, which generates spoofed optimistic SCTP selective acknowledgement (SACK) packet for exploiting a SCTP transmitter terminal as a flood source for Denial-of-Service attacks. The SCTP receiver terminal (120) generates data enriched SCTP SACK packets (170). Each data enriched SCTP SACK packet comprises a cumulative payload essence of all successfully received data packets (200). The SCTP transmitter terminal (110) performs a data enriched SACK validation in which it computes the cumulative payload essence of all successfully transmitted data packets (200), and compares the computed value with the cumulative payload essence contained in the received data enriched SACK. The SCTP transmitter terminal detects a spoofed optimistic SACK packet if the comparison results in a difference.

  • Publication number: 20090325533
    Abstract: Portable battery operated electronic devices often use a “sleep mode” for energy conservation. A key feature introduced in the IEEE 802 standard ensures power-efficient operation of these battery operated mobile devices. However, the standard fails to define what will trigger a device into the sleep mode while other systems define “waiting time threshold” as a time for which a Mobile Subscriber Station (MSS) waits before entering into sleep mode which has a constant duration. An embodiment of the present invention uses a unique method (1500) and algorithm for optimizing waiting time threshold (1509) according to traffic arrival pattern for uplink (UL) and downlink (DL) data packets. This leads to significant reduction in energy consumption with little increase in average waiting delay and acceptable end-to-end delay for non real time traffic.
