Abstract: A method and system for steering a mobile device to a preferred network, such as a Private LTE network or a 5G network, in a scenario in which the coverage area of the preferred network overlaps the coverage area of a non-preferred network. If a network function detects that the mobile device is located within the coverage area of the preferred network, the network steering procedure will be triggered. The mobile device will detach from its current network, place that network on a temporary forbidden list, and perform an automatic network selection. If mobile device selects another non-preferred network, the attachment request will be denied, and the mobile device will add that non-preferred network to the temporary forbidden list. This procedure is repeated until the mobile device attaches to the preferred network or a predefined duration expires.

Abstract: A drilling platform for amphibious operations includes: a base, wherein drive tracks are arranged on both sides of the base, a propeller is disposed at a rear end of the base, and a driving assembly is disposed inside the base; two support cylinders are respectively disposed at two ends of the base; each of the support cylinders contains a sub-cylinder; a pushing cylinder is arranged on a bottom surface of the partition plate; a buoyancy adjustment assembly is provided at a bottom of the base, so as to provide buoyancy support for the base when the base is transferred from land to water. The present invention is suitable for drilling construction of pile foundations of water and land buildings, bridge piers, and transmission line electric tower pile foundations, as well as drilling of oil wells, wherein the drilling platform construction process at different drilling points is omitted.

Abstract: A method for steering a mobile device to a preferred network, such as a Private LTE network or a 5G network, in a scenario in which the coverage area of the preferred network overlaps the coverage area of a non-preferred network. A preferred network list is provisioned into a SIM/eSIM module at the mobile device side. The steering application is hosted at the home network and periodically triggers the home network to request from the visited network a set of values for attributes associated with a current location of the mobile device. Based on these values, the steering application determines whether the mobile device is within the coverage area of the preferred network and, if so, directs the home network to send a cancel location request to the non-preferred visited network, thereby triggering the mobile device to attach to the preferred network.

Abstract: A method and system for steering a mobile device to a preferred network, such as a Private LTE network or a 5G network, in a scenario in which the coverage area of the preferred network overlaps the coverage area of a non-preferred network, such as a 3G or a 4G Public Land Mobile Network (PLMN). A preferred network list is provisioned into a SIM/eSIM module at the mobile device side. The mobile device periodically collects a set of values for attributes associated with a current location of the mobile device and reports the collected values to the Steering application, hosted at the network side. The Steering application detects whether the mobile device is within the coverage area of the preferred network and, if so, triggers the mobile device to perform network steering.

Abstract: The invention relates generally to the field of network connectivity management, specifically to provisioning and controlling the data access of multiple client devices to application servers via a connectivity management device. The invention includes apparatuses, methods, and systems for automating the management of such apparatus and its associating client devices. The management includes initializing and storing device data, ownership proof, connectivity credentials, and security policies into a management system, such as blockchain digital ledger or device management application server. The stored information is used for auto pairing and authenticating the devices via a second wireless technology and triggering secure connection setup over the first wireless technology.
