  • Patent number: 11856411
    Abstract: Methods and apparatus are disclosed for determining spectrum availability within a radio band managed by a Spectrum Management Entity (SME), and allocating available spectrum to Base Station/Access Points (BS/APs) of an Enterprise Network (EN). The EN includes a domain proxy that sends a registration request to the SME indicating a maximum EIRP for the BS/APs. After receiving registration, the Domain Proxy sends a spectrum inquiry and receives a response specifying available spectrum. If less than the entire requested spectrum is available, then the maximum EIRP indication is reduced, and a next iteration is performed re-registering the BS/APs and requesting spectrum. Iterations are repeated until the entire requested spectrum is available, and then spectrum is allocated to the BS/APs. Each iteration of channel availability is stored, and channels are allocated utilizing a Self-Organizing Network (SON) technique responsive to the stored channel availability. The EN may comprise a CBRS Network.

  • Publication number: 20230397135
    Abstract: A method and apparatus are disclosed in which a first UE (User Equipment) receives signals from one or more MNO base stations. The UE synchronizes with the MNO base station timing. The first UE then communicates with a second UE over a wireless side-haul, providing the second UE with timing information derived from the MNO base station. By using the wireless side-haul, a relatively short GPIO (General Purpose Input/Output) connection over a wireline can be used to communicate the timing information from the second UE to a PTP GM (Precision Timing Protocol Grand Master). The second UE may be integrated into a cell of a communications network that contains the PTP GM. Accordingly, using the side-haul to communicate the timing information avoids cabling to a master cell.

  • Patent number: 11683717
    Abstract: A transfer management system for efficiently operating an enterprise wireless communication network (EN) at a campus location enables the EN to control congestion, selectively and smoothly admit UEs, and manage UE exits from the EN. An MNO Network (MN) footprint learning system learns the different MN footprints on the campus, relative to the BS/APs deployed by the individual enterprise, which defines a footprint of wireless coverage for each MNO that has wireless coverage. The MN footprint provides useful information that enables successfully transitioning a UE between an EN and an MNO, which provides the EN with the ability to utilize other networks to offload one or more UEs to manage congestion, delay or deny admission of UEs, and proactively exit UEs to manage congestion or for other reasons.

  • Publication number: 20230121880
    Abstract: A method and apparatus for utilizing microslices in an enterprise wireless communication network to manage and control network performance. The microslice instances are monitored during network operation, for example at communication nodes, functional blocks, and end-to-end to provide Key Performance Indicators (KPIs). These KPI are compared with performance objectives, which may be Service Level Objectives (SLOs). If the performance objectives are not met by the KPIs, then one or more of the microslice instances may be dynamically adjusted until the performance objectives are sufficiently met. Alternatively, the lower priority microslice instances may be dropped (i.e., terminated) until the performance objectives are sufficiently met.

  • Publication number: 20230071539
    Abstract: A method and apparatus for allocating radio resources in a RAN deployment in an Enterprise Network. Radio resource parameter allocation decisions for all the Base Stations and Access Points (BS/APs) in the deployment are made responsive to network graphs formed using predicted path loss. In one embodiment the predicted path loss values are simulated for a particular enterprise network deployment, network graphs are formed using the path loss values, and radio resources parameters are allocated responsive to the network graphs. Advantageously, the network graphs provide the network with the ability to quickly and efficiently allocate radio resources, which can be automated. In the initial installation, this reduces cost and time. During operation, quick and efficient resource re-allocation provides quick adaptation to resource changes, an advantage that is useful particularly in the context of a CBRS system in which previously-available channels can be terminated.

  • Publication number: 20230043668
    Abstract: In selected embodiments, on-premises equipment of a cellular network provides local breakout functionality so that user plane data packets (PDNs/PDUs) are routed between the home/enterprise network and the Internet directly, bypassing a cloud-based core of the cellular network. The UE's control traffic is still routed to/from the core. The core may be an Evolved Packet Core (EPC) in a 4G LTE network, or a 5G Core (5GC) in a 5G network. The UE's IP addresses may be assigned by the core, or locally, by the on-premises equipment. Providing the IP context from the on-premises network allows the UE to connect to local devices, e.g., printers, disc raids, gaming and streaming nodes, and other local devices. The local IP context also pushes the complexity of the EPC core deployment to the cloud while reducing the overhead of cloud processing that comes with user plane data processing.

  • Patent number: 11558924
    Abstract: A method and apparatus for managing wireless Enterprise Networks (EN) for greater efficiency by developing inactivity timers for packet streams on bearers, monitoring the packet streams of UEs on the bearers, and if inactivity is found determining whether or not to release or modify a bearer, or maintain the current status of the UE considering factors such as congestion, expected lull time, reconstruction cost, and UE type and location. Accordingly, UEs can be more efficiently allocated the EN's available resources. To learn the timers, packet streams are monitored over a period of time, the packet streams are sorted by service type and bearer (and optionally time), and an inter-burst packet arrival time is determined. Timers are developed that provide inactivity time limits and an expected lull time that predicts the behavior of the packet streams based on service type and bearer, and optionally time.
