Description

Method for establishing an operational mobile radio connection for a measuring system reference to related applications The present application claims priority from German patent application No. 10 2023 206 301.8, filed on July 3, 2023, which is incorporated herein by reference in its entirety. background Machines, systems, devices or sensors that can be connected to the Internet via a wireless connection in accordance with the Internet of Things are typically set up by the manufacturer in such a way that they can be wirelessly connected to the Internet using a SIM card based on a mobile phone contract. disclosure of the invention If a device such as a machine, a production system or a sensor is fitted with a SIM card at the time of production, a poor connection or no connection at all to the mobile network selected in accordance with the mobile phone contract may be established at the location where the device is used. Alternatively, another mobile network may also offer mobile phone connections at the location where the device is used, which could provide a better connection to the Internet. According to aspects of the invention, a method for establishing an operational mobile radio connection, a measuring system, a computer program and a machine-readable storage medium according to the features of the independent claim are proposed. Advantageous embodiments are the subject of the dependent claims and the following description. Throughout this description of the invention, the sequence of process steps is presented in such a way that the process is easy to understand. However, those skilled in the art will recognize that many of the process steps can also be carried out in a different order and lead to the same result. In this sense, the order of the process steps can be changed accordingly and is therefore also disclosed. According to one aspect of the invention, a method for establishing an operational mobile radio connection for wireless data transmission from a measuring system to a data receiver is provided, the method comprising the following steps: In one step, a large number of mobile phone connections that are offered in an environment of the measuring system are detected. In a further step, at least a portion of the large number of mobile phone connections offered is characterized by determining technical operating criteria for the respective mobile phone connection and/or querying economic operating criteria for the respective mobile phone connection. In a further step, the operational mobile phone connection is determined based on the characterization of at least a portion of the large number of mobile phone connections offered. In a further step, the operational mobile phone connection is established from the measuring system to the data receiver using an operator profile for the operational mobile phone connection. The measuring system can be a sensor system or any device that is designed to transmit data wirelessly to a data receiver. The operational mobile radio connection can be a mobile radio connection that is set up to wirelessly transmit the data of the measuring system to the data receiver. The data receiver can be set up with a storage unit to save the data of the measuring system and make it available for further evaluation. The data receiver can be a user of the measuring system and/or a provider of the measuring system. The Mobile phone connections whose electromagnetic radiation can be detected by the measuring system can be offered in the vicinity of the measuring system. The operator profile may include the operator data related to a mobile subscription, including operator credentials and possibly SIM-based applications from the operator or third parties. The secure element of an embedded subscriber identification module (eSIM) solution is an embedded universal integrated circuit card (eUlCC) that can store multiple operator profiles. Operator profiles can be remotely downloaded wirelessly to an eUlCC. An eSIM card or an iSIM card can be described as a SIM card with an overwritable operator profile, allowing a change of mobile operator or mobile connection without physically replacing the SIM card. In other words, the measuring system can be set up and configured to scan and/or determine mobile phone connections at a location in the vicinity of the measuring system that are particularly suitable for wireless data transmission from the measuring system to the data receiver. The measuring system can also be configured and set up to book and/or select and/or activate the operator profile and/or a suitable mobile phone contract from an associated provider of the particularly suitable mobile phone connection. Advantageously, the method can be used to set up the most suitable mobile radio connection for wireless data transmission, which makes it possible to set up the most suitable operational mobile radio connection at a location where the measuring system is used, even if a diff
