  • Publication number: 20240014551
    Abstract: Methods, apparatus, and systems for dynamic antenna tilt coordination. In one embodiment, real-time data from user equipment (UE) measurement reports are aggregated across multiple base station entities. State input for a machine learning algorithm may be generated from the aggregated UE measurements. The machine learning algorithm may be trained to maximize a real-time network consideration (such as data throughput) by adjusting antenna tilt. During operation, the machine learning algorithm provides tilt settings to each of the radio units (RU) of a base station. Live feedback allows the machine learning algorithm to robustly handle a variety of conditions (e.g., weather, data traffic, etc.

  • Patent number: 9686360
    Abstract: LTE and HSPA/UMTS deployments are trending towards high density, heterogeneous and ad-hoc deployments. These deployments can be managed through Self-Organizing Network (SON) schemas. Enabling SON generally involves the introduction of new software and/or hardware entities into the network that can interact with existing base station and network entities (e.g., Enhanced Packet Core, Element Management System, and/or other network entities). In one embodiment, these interactions include the development and deployment of interfaces (e.g., APIs) and protocols between the SON entities and various network entities. For example, data collected on either side of an interface or protocol can be post-processed before consumption (e.g., for both data integrity purposes as well as bandwidth reduction purposes).

  • Patent number: 9485743
    Abstract: Apparatus and methods for synchronizing a network element (e.g. access points, femtocells, etc.) to a master network (such as a cellular network) to provide accurate frequency and/or time references for their internal systems. In one embodiment, the network element utilizes a dedicated receiver (or transceiver) to receive timing information from the master network. The implementation of the dedicated receiver is advantageous for cost and simplicity reasons. Furthermore, the timing or frequency information, as received from the master network, is used to correct the network element's internal timing. In addition, the network element's internal timing can operate in open-loop mode, if no master network can be found, thereby allowing for the device to continue providing service to network users. Additionally, a dedicated receiver can also receive information (e.g. location, SID, NID, SSID, etc.
