Description

Technical field

[0001] Exemplary embodiments of the present invention relate to devices, methods and computer programs for providing defined radio access for a mobile device through an access node, in particular but not exclusively for automatically registering mobile devices for wireless communication with a plurality of access nodes for connection to the Internet or other networks. background

[0002] It is well known that mobile devices, also called mobile stations, connect to the internet or other networks via a Wireless Local Area Network (Wireless LAN or WLAN). WLAN refers to a local wireless network, usually based on a standard from the IEEE 802.11 family (Institute of Electrical and Electronics Engineers). Variations based on Bluetooth and other wireless standards are also used. A key feature of such internet or alternative network access is an access point.

[0003] Access nodes can be installed in vehicles to enable communication between vehicle occupants, or more generally, users. The access node establishes a connection between users' mobile devices and the internet or other networks. This allows users to access internet services or similar network services with their mobile devices, much like they would with stationary access points. Mobile devices are assigned an IP (Internet Protocol) identifier and a MAC (Medium Access Control) identifier, both of which are necessary for internet communication.

[0004] Access to the internet or similar networks is generally restricted. It is intended to be made available only to specific devices or users. This distinguishes the implementation discussed here from publicly accessible internet access points, also known as hotspots, which allow any compatible mobile device access to the internet. This access restriction for specific devices and / or users is implemented through a registration process, in which the mobile device and / or user identifies itself using a corresponding identifier. Optionally, further authentication of the mobile device and / or user is performed to prevent misuse. After this registration, the mobile device can reconnect to the access point at any time, provided it is within range of the access point's wireless connection.Re-establishing this connection can also be referred to as registering the mobile device with the access node.

[0005] However, this requires re-registering mobile devices and / or users at each new access point. Users may find this cumbersome and time-consuming, especially if they have to log in to the same access point in similar environments. This inevitably results in a potentially long list of possible login credentials. A similar environment could be, for example, the various vehicles in a car-sharing provider's fleet (vehicle rental service) equipped with access points. Company or other organization fleets can also encounter this problem.

[0006] German patent application DE 10 2016 220 229 A1 describes a method, system, and vehicle for automatically transmitting device pairing data to a vehicle. German patent application US 2015 / 024688 A1 describes wireless pairing, and in particular the automatic pairing, of a vehicle and a mobile device to authenticate wireless communication between the mobile device and the vehicle. German patent application DE 102015 226 643 A1 describes devices, methods, and a computer program for establishing a communication link between a vehicle's information system and a mobile device. German patent application DE 10 2009 037 234 A1 describes a method for at least unidirectional transmission of data between a data processing unit located outside a motor vehicle and each individual motor vehicle from a fleet of motor vehicles.

[0007] There is therefore a need to provide access for a mobile device and / or a user in comparable environments without having to perform a new login procedure, also called registration, with the respective access node each time it is used for the first time. The methods, devices, and computer programs according to the independent claims address this need. Summary

[0008] A key concept of the invention is to offer mobile devices the same access credentials at all access points belonging to a specific organization (for example, in the vehicles of a car-sharing fleet or the vehicles of a company or other organization). Only a single login is required for these credentials. Afterward, all access points can provide these credentials to the mobile device, allowing it to register without a new login process at each access point. For this to work, the mobile device, or rather the user, must be known to the respective access point. Alternatively, the access credentials can also be obtained by the access point through a query at the central unit.

[0009] Exemplary embodiments relate to a method for providing defined wireless access to a mobile device via an access node. This method includes receiving configuration data for the defined wireless access from a central unit based on the identification of the mobile device or a user of the mobile device. The configuration data includes a user-specific WiFi SSID (Service Set Identifier) ​​and an associated password. The method further includes the access node providing the defined wireless access to the mobile device based on the configuration data from the central unit.

[0010] This can advantageously avoid the repeated registration of mobile devices or users when the device is set up for the defined radio access and is within range of a new access node.

[0011] In some implementation examples, the defined radio access can enable automatic registration of the mobile device based on the previously known data contained in the configuration data.

[0012] The advantage of automatic registration is that the mobile station can connect to the internet or alternative networks such as an intranet without any further identification or authorization procedure, i.e., without registration. This makes access for users and devices as straightforward as with a known access point.

[0013] In other embodiments, the defined radio access, which is understood in the sense of establishing a communication connection, can be based on WLAN, Bluetooth, UWB - Ultra Wideband, NFC - Near Field Communication - or DECT (Digital Enhanced Cordless Telecommunications).

[0014] This makes it advantageous to connect to a wide variety of mobile devices, as the standardized transmission methods are widely used.

[0015] Furthermore, the WLAN is configured as WiFi, the access node is configured as a WiFi access node, and the access node provides a WiFi SSID - Service Set Identifier.

[0016] This allows access nodes and mobile devices to be limited to the most common form of local wireless access, WLAN qualified as WiFi, which reduces costs, space and power consumption in access nodes and mobile devices.

[0017] In some embodiments, the access node can be located in a vehicle.

[0018] This method offers the advantage of providing mobile internet access.

[0019] In further embodiments, a connection between the access node and the central unit can be established via a radio connection according to cellular mobile communications or WLAN.

[0020] This allows for the advantageous use of widely adopted mobile communication standards, which enable cost-effective implementation and can draw on a large number of existing connection points of the installed networks.

[0021] In exemplary implementations, the access node can automatically detect the identification of a mobile device or a user of the mobile device within range and transmit it to the central unit.

[0022] This allows the central unit to advantageously register user behavior and make it available for appropriate evaluations.

[0023] In some implementation examples, the configuration data can be based on information from a previous registration of at least one mobile device at the central station.

[0024] This approach ensures that configuration data is only created if at least one mobile device is registered for use in the vehicles, for example, in a car-sharing fleet. Furthermore, the central station can record user behavior and make it available for relevant analysis.

[0025] In some implementation examples, the provision of configuration data may be restricted to a group of authorized access nodes.

[0026] This allows for advantageous control of internet access, which can be linked, for example, to a corresponding fee or vehicle categories.

[0027] In some implementation examples, the configuration data can be based on customer data, and a set of configuration data can be generated for each customer.

[0028] This advantageously enables a customer-oriented structure that can be easily combined with associated reservation and billing systems, which are themselves organized in a customer-oriented manner.

[0029] In some implementation examples, one or more mobile devices can be assigned to the configuration data.

[0030] This advantageously enables the use of various mobile devices belonging to the customer, which may also be connected to the internet simultaneously, without requiring the creation of a new configuration data set.

[0031] Further embodiments relate to access nodes for providing defined wireless access for a mobile device. These include an interface configured to receive configuration data for the defined wireless access for the mobile device from a central unit, based on an identification of the mobile device or a user of the mobile device. The configuration data includes a user-specific WiFi SSID (Service Set Identifier) ​​and an associated password. The access nodes also include a provisioning unit for providing the defined wireless access for the mobile device, based on the configuration data from the central unit.

[0032] Furthermore, embodiments relate to a computer program for carrying out one of the methods according to the relevant embodiments, when the computer program is executed on a processor, microcontroller or programmed hardware component.

[0033] Furthermore, exemplary embodiments relate to a method for a central unit to provide configuration data for a defined wireless access point to a mobile device via an access node. The method includes receiving an identification of the mobile device or its user and an identification of the access node. It further includes the provision of configuration data for the defined wireless access point from the central unit based on the identification of the mobile device or its user. The configuration data includes a user-specific WiFi SSID (Service Set Identifier) ​​and an associated password. The method also includes the transmission of the configuration data for the defined wireless access point of the mobile device from the central unit to the identified access node so that the access node can provide the defined wireless access point to the mobile device.

[0034] The central management and provision of configuration data can advantageously ensure the avoidance of multiple logins by a mobile device and / or user when using different access nodes.

[0035] In exemplary implementations, the identification of the mobile device can be based at least on a MAC (Media Access Control) address, an Ultrawideband (UWB) hardware address, a Bluetooth (BT) hardware address, a customer-specific application identification, or a mobile device instance identification.

[0036] This allows access to a large number of mobile device and / or user identities, which, due to their standardization, have a wide distribution and thus cover a large number of mobile stations.

[0037] Furthermore, exemplary embodiments relate to a central unit for providing configuration data for a defined wireless access point to a mobile device at an access node. This central unit comprises one or more interfaces configured (i) to receive an identification of the mobile device or a user of the mobile device. They are also configured (ii) to receive an identification of an access node. The central unit further comprises a provisioning unit configured to provide configuration data for the defined wireless access point based on the identification of the mobile device or the user of the mobile device. The configuration data includes a user-specific WiFi SSID (Service Set Identifier) ​​and an associated password.Furthermore, one or more interfaces are further developed (iii) to transmit the configuration data for the defined radio access for a mobile device to the identified access node.

[0038] Furthermore, embodiments relate to a computer program for carrying out one of the process-related embodiments for a central unit, when the computer program is executed on a processor, microcontroller or a programmed hardware component. Character description

These show: Fig. 1 a known signaling sequence for providing radio access to a mobile device through an access node; Fig. 2 the inventive signaling sequence for providing radio access to a mobile device through an access node according to an embodiment; Fig. 3 a schematic representation of a method for providing defined radio access to a mobile device through an access node according to an embodiment; Fig. 4 an access node for providing defined radio access for a mobile device according to an embodiment; Fig. 5 a further schematic representation of a method for a central unit for providing configuration data of a defined radio access for a mobile device through an access node according to an embodiment; and Fig. 6 a central unit for providing configuration data of a defined radio access for a mobile device to an access node according to an exemplary embodiment. Detailed description

[0040] The invention relates to a method, a device, and a computer program for providing defined wireless access to a mobile device via an access node. Various embodiments of the invention are now described in more detail with reference to the accompanying drawings, in which some embodiments are illustrated. For the sake of clarity, the thickness dimensions of lines, layers, and / or regions may be exaggerated in the figures.

[0041] In the following description of the accompanying figures, which merely show some exemplary embodiments, the same reference numerals can denote identical or comparable components. Furthermore, collective reference numerals can be used for components and objects that appear multiple times in an embodiment or in a drawing, but are described jointly with respect to one or more features. Components or objects described with the same or collective reference numerals can be identical with respect to one, several, or all features, such as their dimensions, but may also differ, unless the description explicitly or implicitly indicates otherwise.

[0042] Although embodiments can be modified and altered in various ways, they are shown in the figures as examples and are described in detail herein. It should be clarified, however, that the intention is not to limit embodiments to the forms disclosed, but rather that they are intended to cover all functional and / or structural modifications, equivalents, and alternatives within the scope of the invention. The same reference numerals throughout the figure description denote identical or similar elements.

[0043] Note that an element described as "connected" or "coupled" to another element may be directly connected or coupled to that element, or there may be intervening elements. Conversely, if an element is described as "directly connected" or "directly coupled" to another element, there are no intervening elements. Other terms used to describe the relationship between elements should be interpreted similarly (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.).

[0044] The terminology used herein serves only to describe specific embodiments and is not intended to limit the scope of these embodiments. As used herein, the singular forms "a," "an," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, it should be clarified that expressions such as "includes," "containing," "exhibits," "comprises," "comprising," and / or "indicating," as used herein, indicate the presence of the aforementioned features, integers, steps, workflows, elements, and / or components, but do not preclude the presence or addition of one or more features, integers, steps, workflows, elements, components, and / or groups thereof.

[0045] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning that an average person skilled in the field to which the examples of implementation belong would ascribe to them. Furthermore, it should be clarified that expressions, e.g., those defined in commonly used dictionaries, are to be interpreted as having the meaning consistent with their meaning in the context of the relevant technology, and not in an idealized or overly formal sense, unless expressly defined herein.

[0046] The components described here and below are described as "designed to" or "configured to" perform or fulfill a certain function, with these terms being used synonymously and interchangeably. Each such component is capable of performing the described function because, for example, the corresponding software is present or stored in memory. For instance, a control module designed or configured to control a transceiver module and implemented in programmable hardware must be designed such that appropriate control software for controlling the transceiver module is present.

[0047] Fig. Figure 1 illustrates a known provision 90 of wireless access for a mobile device via an access node. This involves a mobile device 91 and an access node 92, which may be located in a vehicle. This access node 92 transmits a unique SSID (Service Set Identifier) ​​910. Upon receiving the SSID, the mobile device recognizes the access node 920. The mobile device then prepares for the connection 930, which may include displaying the SSID to the user. The user then enters a corresponding password into the mobile device 940. The mobile device subsequently sends a WiFi Connect message to the access node 950. The access node provides an IP address 960, which is transmitted to the mobile device 970.As an alternative to the WLAN implementation described here, implementations according to other radio standards or proprietary radio methods with their respective identifications and signals can also be used, for example according to Bluetooth, UWB - Ultra Wideband -, NFC - Near Field Communication - or DECT.

[0048] Fig. Figure 2 illustrates the inventive process, wherein the process steps according to claim 1 are shown with solid lines and the remaining process steps are shown with dashed lines. Further process steps, some of which are claimed in the dependent claims, are shown with dashed lines. Similarly, Figure 2 shows... Fig. 2 A schematic representation of a method for providing 100 defined radio access to a mobile device via an access node. The processes between a mobile device 101, a first access node 102 located in another vehicle, a second access node 103 located in a vehicle, and the central unit 104 are described. The following steps are performed: In a first step, the user or mobile device 101 registers with the central unit 104 using a signal 1010. This can be referred to as a login or registration request. The signal contains data for the automatic identification of the mobile device. This identification can be based on the radio standard used. Accordingly, the mobile device identification can be based on at least a MAC address, an ultrawideband (UWB) hardware address, a Bluetooth (BT) hardware address, or the like. Furthermore, a proprietary identification can be used for a proprietary standard. A mobile device-specific identification can also be used. Multiple identifications are also possible. Additional user data can also be transmitted, which is useful for car sharing, billing, creditworthiness, etc.If a plausible registration signal is received, the central unit creates the configuration data 1020, which can also be referred to as the user profile or the profile of the mobile device or the customer, and stores it in memory. The central unit 104 then transmits the configuration data to the mobile device 1025. In the case of a WLAN connection between the mobile device 101 and the access nodes, the configuration data includes an SSID (Service Set Identifier) ​​and a corresponding password. In the case of Ultra-Wideband, a UWB hardware address is transmitted. In the case of Bluetooth, a BT hardware address is transmitted. In the case of DECT, a secret key is transmitted, which the mobile device uses to authenticate itself to the access station. The mobile device stores this configuration data in memory. This completes the actual login or registration process.

[0049] To register the mobile device 101 with the first access node 102, which may also include data for car sharing such as vehicle identification, the mobile device sends a signal 1030 to the central unit 104. This signal contains at least an identifier of the terminal device and / or a user identifier, as well as data to identify the first access node 102. The central unit 104 assigns the corresponding configuration data and transmits it in signal 1040 to the first access node 102 in the vehicle. The configuration data includes the aforementioned identification of the mobile device and / or user, as well as a corresponding password. The first access node 102 then provides the defined radio access for the mobile device 101 (1050). This process can also be referred to as preconditioning the access node.

[0050] This preconditioning includes providing the mobile device identifier and / or the user identifier. When the mobile device 101 is within range of the first access node 102, it can notify the access node 102 of its presence (1060). The access node 102 then sends the mobile device identifier and / or the user identifier (1070). In the case of Wi-Fi, this could be the SSID. The mobile device 101 recognizes the SSID or the mobile device identifier and / or the user identifier and automatically associates it with the password received during the login process, i.e., without user intervention. This password can be used to decrypt the signals received from the first access node 102. The mobile device 101 then sends a signal (1080) to the first access node 102, confirming the mobile device's registration with the first access node. In the case of Wi-Fi, this is a reconnect signal (Wi-Fi auto reconnect).

[0051] Wi-Fi CERTIFIED™ is an internationally recognized seal of approval for products, indicating that they meet industry-standard requirements for interoperability, security, and a range of application-specific protocols.

[0052] Not shown in Fig. The following processes occur: Following registration, a data transfer may take place, which also includes signal transmission between the access nodes and the internet or other networks. This signal transmission may involve a radio connection established according to one of the WLAN standards according to 802.11 and / or according to a cellular mobile communication standard. Subsequently, the mobile device may deregister from the first access node 102.

[0053] If necessary, at a later time the mobile device 102 can again send a signal 1130 to the central unit 104, this time aiming to establish a connection between the mobile device and the second access node 103 and containing data to identify the second access node 103. Analogous to signal 1040, signal 1140 provides the configuration data to the second access node. In process 1150, the second access node 103 provides the defined radio access for the mobile device 101. When the mobile device 101 is within range of the second access node 103, it can notify the access node 102 of its presence (1160). The latter then sends the mobile device identifier and / or the user identifier (1170). The mobile device 101 then sends a signal (1180) to the second access node 103, confirming that the mobile device 101 has registered with the second access node 103.Accordingly, each authorized access node provides the mobile device and / or user with at least partially identical, defined radio access. The mobile device receives the same known signals from each authorized access node, for which the mobile station has already registered, thus enabling a corresponding password assignment.

[0054] In some implementation examples, the defined wireless access can enable the automatic registration of a mobile device or a user of that mobile device. This can involve the exchange of an identifier for the mobile device or the user. Furthermore, it can allow the assignment of an IP (Internet Protocol) or MAC address to the mobile device, which is necessary for its internet access. The defined wireless access can also encompass various air interface methods, which, depending on the application, may be widely used in mobile devices or be proprietary and are typically designed for medium and short distances between the mobile station and the access node. Examples include the WLAN (Wireless Local Area Network) standard of IEEE 802.The 11 family, also known as WiFi in a certified form, can be used. Bluetooth, a widely used wireless standard for shorter connections, Ultra-Wideband (UWB), DECT (Digital Enhanced Cordless Telecommunications), or Near Field Communication (NFC) can also be employed. Proprietary systems can be designed for government applications, for example, for the armed forces, police, fire department, or similar organizations.

[0055] In various embodiments, mobile devices can be portable devices such as cell phones, tablets, laptops, portable computers, or radio modules, or the like. They can also be integrated into clothing or accessories, for example, as glasses, a USB modem, or similar items. Mobile devices, also called handheld devices, can also be assigned to users if they are capable of communicating user data.

[0056] In exemplary implementations, the defined radio access of the access node can be based on the WLAN or WiFi radio standards. Access nodes can be stationary or mobile. Examples of mobile installations include placement in vehicles, such as cars, trains, or aircraft. Access nodes can be connected to central units, either via a wired connection or an wireless interface. Alternatively, access nodes can communicate with mobile devices using the defined radio access. Various methods are applicable here (see above for defined radio access), which can be used individually or in combination. The access nodes can offer encryption via the defined radio access to the mobile station, at least for certain procedures, such as during the login process or authentication of the device and / or access node.Access nodes can also be referred to as a WiFi network.

[0057] In practical examples, configuration data defines the mobile station's radio access. This data can include the information required for the mobile device or user to register. In the case of WLAN, this information can be configured as an access node identifier, such as the SSID (Service Set Identifier), and a password, more generally a key, and may include a WLAN identifier that specifies the frequency band used, the data rate, etc. The configuration data can be stored in the access node itself. However, it can also be stored in other network elements, such as central units of an operator, company, or organization. This could also include a company's car-sharing service. The provision of configuration data for a specific access node can be linked to a higher-level procedure, such as booking a specific vehicle from a car-sharing company.The configuration data is transmitted to the access node in the rented vehicle. This allows the access node to send or store the data appropriate for the mobile device or user. The configuration data can be created or completed during the registration of the mobile station or the user. It can also be modified or deleted by the company's administration function or, at least partially, by the user.

[0058] In some implementations, the access node can be identified by its IP address, particularly if the connection between the access node and the central unit is at least partially via the internet. For proprietary networks, such as an intranet, corresponding identifiers can be used.

[0059] In some implementations, the central unit can be configured as one or more servers belonging to a company that, for example, offers car sharing. This central unit, also referred to as the BMW back end, backend, or back-end management entity, can store additional customer information alongside the configuration data, in addition to the data for identifying a user and / or their associated mobile device. This can include billing data, statistical data, data relating to other services the company provides to the user, and similar information. The configuration data can be made available to the access node via the internet. Alternatively, or in addition to this, a connection can also be established via a wireless interface, for example, through cellular mobile communications or Wi-Fi.

[0060] In some implementations, identification of the mobile device or user allows for the unique assignment of the mobile device or user to at least one set of configuration data. In WLAN, this can consist of a MAC (Medium Access Control) address. For other wireless standards, corresponding elements for identification are defined. Using this identification, the mobile device or user can be registered. This registration can be performed as a one-time process, during which the configuration data is also generated or modified. Following registration, the mobile device and / or user can log in. This login process can also be referred to as a login procedure. Authentication of the mobile device and / or user and / or the access node during login or registration can also be included.

[0061] In some implementation examples, the user of the mobile device may be known to the service provider, for example, a car-sharing service. Their information may be recorded in the configuration data or in other data associated with the configuration data. The user may also be referred to as a customer. Their mobile devices may also be referred to as customer devices.

[0062] Mobile devices can support one or more radio standards, depending on the application. They can be designed as freely available standard devices, as mentioned above, or as specialized devices for specific applications.

[0063] In some implementation examples, the defined wireless access can enable automatic registration of the mobile device (1080, 1180) based on previously known data contained in the configuration data. This automatic registration can occur within range of the access node, for example, when the mobile device assigns the corresponding password to an SSID and confirms the WiFi connection with the WiFi Auto Re-Connect signal (1080, 1180). This completes the automatic registration process. Registration can also be referred to as automatic detection of customer devices.

[0064] In exemplary embodiments, the access node can be located in a vehicle, Fig. 2 102, 103. This includes all types of passenger cars, trucks, buses and other motor vehicles, as well as motorcycles or bicycles. Its use in trains or other rail-bound vehicles is also conceivable. Its use in aircraft or ships is also possible.

[0065] In exemplary implementations, mobile communication standards according to the 3 can be used. rd The system must be a member of the Generation Partnership (3GPP) organization and be designed for Global System for Mobile Communications (GSM), Enhanced Data rates for GSM Evolution (EDGE), GSM EDGE Radio Access Network (GERAN), High Speed ​​Packet Access (HSPA), Universal Terrestrial Radio Access Network (UTRAN) or Evolved UTRAN (E-UTRAN), Long Term Evolution (LTE) or LTE-Advanced (LTE-A), or mobile communication systems with other standards, for example, Worldwide Interoperability for Microwave Access (WIMAX) IEEE 802.16. Furthermore, it can be a system based on Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Code Division Multiple Access (CDMA), etc.

[0066] In addition, the core functions of the invention are in Fig. 3 shown, wherein the method 10 is suitable for providing a defined radio access for a mobile device through an access node (10, 100) and comprises the following steps: Receiving (110) configuration data for the defined radio access from a central unit based on an identification of the mobile device or a user of the mobile device; and Providing (120) the defined radio access for the mobile device by the access node based on the configuration data of the central unit.

[0067] The defined radio access enables automatic registration of the mobile device based on the pre-existing data contained in the configuration data 130. It is functionally linked to the provision of the defined radio access for the mobile device 120.

[0068] The defined wireless access is based on WLAN, Bluetooth, UWB (Ultra Wideband), NFC (Near Field Communication), or DECT 140. It is functionally linked to receiving configuration data 110.

[0069] The WLAN can be configured as WiFi, the access node can be configured as a WiFi access node, and / or the access node can provide a WiFi SSID (Service Set Identifier). They are functionally connected to the defined wireless access point.

[0070] The access node can be located in a vehicle 160 that is functionally connected to the method 10.

[0071] A connection between the access node and the central unit can be established via a radio link according to cellular mobile communications or WLAN 170, which is functionally connected with the provision of the defined radio access 120.

[0072] A preset of the defined radio access can be based on an access procedure of a vehicle or geographical location assigned to the access node 180, which is functionally linked to the procedure 10.

[0073] The access node can automatically detect the identification of a mobile device or a user of the mobile device within range and transmit it to the central unit 190. This is functionally linked to the provision of the defined radio access 120.

[0074] The configuration data can be based on information from a previous registration of at least one mobile device at the central station 210, which is functionally linked to the procedure 10.

[0075] The provision of configuration data can be restricted to a group of authorized access nodes 220, which are functionally linked to receiving configuration data 110. Such a group of authorized access nodes can refer to the fleet of usable vehicles, for example, the fleet of the car-sharing company or the vehicle fleet of a company or other organization such as the police, fire department, etc. Within a car-sharing provider, only certain access accounts may be activated in vehicles, which can be designed, for example, based on the tariff. Temporary or local restrictions are also conceivable.

[0076] The configuration data can be based on customer data, and a set of configuration data can be generated per customer (230), which is functionally linked to the receipt of configuration data (110). Customer data can include, in addition to names and addresses, payment methods, creditworthiness information, sales limits, sales history, vehicle booking history, mileage, rental locations, and similar historical or current information. The user's registered mobile devices can also be stored. The customer data can be updated, at least partially, by the customer, which can also be done via mobile devices, preferably with a suitable application.

[0077] The configuration data can be associated with one or more mobile devices (240), which are functionally linked to receiving configuration data (110). These mobile devices can be of the same or different types. In some cases, the users of the devices can also be stored, using data transmitted by the mobile devices, data related to the mobile device hardware, and / or data related to the air interface type. Users can log in and out of mobile devices.

[0078] Further embodiments relate to access nodes for providing defined radio access to a mobile device.

[0086] In other words, the invention can be described as follows: Vehicle manufacturers are beginning to install Wi-Fi hotspots in their vehicles to allow users to connect to the internet with their handheld devices or laptops. The use of these hotspots is typically implemented in a manner similar to that of home routers. Once the hotspot is activated in the vehicle, each handheld device must search for the Wi-Fi SSID, select the Wi-Fi network, and enter the password. It is assumed that the user has previously requested or looked up the password in the system. This process is repeated each time passengers wish to use the Wi-Fi hotspot in a new vehicle. It must also be repeated for each additional device a passenger wishes to connect.

[0087] Carsharing and ridesharing applications are well-known, allowing users to utilize many different vehicles. The user experience is cumbersome, as they must repeat the registration process at each Wi-Fi hotspot.

[0088] Therefore, an innovative system is proposed that eliminates all repeated login procedures and requires only one registration for each device connected to the BMW backend. This registration can take place in a vehicle, at a suitable terminal, at home, or via a smartphone app. During this one-time registration process, a unique profile of the customer's mobile device is created, which is then used as a secure element to grant access to all authorized hotspots. Each time the customer enters a hotspot's coverage area, the hotspot recognizes the customer's mobile device and compares it to their unique profile. This profile is then used to establish a unique Wi-Fi network with a distinctive (hidden) SSID, to which the customer's mobile device connects.This means that no password entry is required on the customer's side, as the unique WiFi network is already known to the customer's mobile device.

[0089] The functionality is enabled by a back-end management entity that manages the unique customer profile and initiates the setup of the customer-specific WiFi in the vehicle.

[0090] The main aspects of the invention are: • Unique SSID / password assigned to a customer account • Number of customer devices linked to the customer account (backend managed) • Automatic detection of customer devices using Wi-Fi, Bluetooth, UWB (Ultra Wideband), NFC (Near Field Communication), DECT hotspot or other methods in the vehicle • Preconditioning of the customer's vehicle with individual customer-specific SSID / password

[0091] Advantages of the proposed invention are: • Ease of use for WLAN, Bluetooth, UWB (Ultra Wideband), NFC (Near Field Communication), DECT hotspot or other methods. • Register only once. • Automatic connection to all WLAN, Bluetooth, UWB (Ultra Wideband), NFC (Near Field Communication), and DECT hotspots where the customer is authorized.
