Description

Communication module, vehicle and method for operating a communication module
Technical Field
The present disclosure relates to a communication module, in particular for a vehicle, such as a vehicle, a vehicle having such a communication module, and a method for operating such a communication module. In particular, the present disclosure relates to communication in a mobile network using esims.
Background
Networking of modern vehicles, for example with the internet, is becoming increasingly important. For example, cloud-based services are available to users in vehicles. To enable the use of these and other services, the vehicle includes a communication module that communicates, for example, using a SIM card. The devices necessary for communication, such as SIM cards, may be country specific. Thus, when a vehicle crosses a country boundary, it may occur that the communication module is not usable. This is inconvenient for the user of the vehicle, in particular because of the increasing importance of networking the vehicle with the outside world.
Disclosure of Invention
The object of the present disclosure is to specify a communication module, in particular for a vehicle, such as a vehicle, a vehicle having such a communication module, and a method for operating such a communication module, which ensure the functionality of a communication function.
This object is achieved by the measures of the independent claims. Advantageous embodiments are given in the dependent claims.
According to a separate aspect of the present disclosure, a communication module, in particular for a vehicle, such as a vehicle (e.g. a motor vehicle), is presented. The communication module includes a certificate module including two or more digital certificates, an eSIM module, and a selection module. The selection module is configured to select one digital certificate from the two or more digital certificates as appropriate to enable communication in a mobile network using the selected digital certificate and the eSIM module or an eSIM Profile (Profile) existing in the eSIM module.
eSIM (embedded subscriber identity module) is a standardized method for securely embedding subscriber information in a module of a telecommunication device. Security or data confidentiality is crucial for communication by means of esims. In this regard, the module includes a standardized digital certificate. There are a large number of different certificates worldwide in which a certain kind of eSIM functions only with a certain kind of certificate.
According to the present invention, two or more digital certificates are held in a communication module. Which digital certificate to use is decided according to circumstances. For example, a chinese user using a vehicle in germany may load and use his chinese eSIM profile in the vehicle. Thereby, the functionality of the communication function can be ensured. Further, users that traverse national boundaries with their vehicles may load and use eSIM profiles for other countries, for example, in order to save roaming fees.
In the context of the present disclosure, the term "case-by-case" means the selection of a digital certificate that can fulfill the communication function in the current case. In this regard, the current situation depends on the user and in particular on the user's eSIM profile. Thereby, the term "as the case may be" may mean selecting a digital certificate appropriate for the eSIM profile of the user. Thereby, the functionality of the communication function can be ensured.
Preferably, the two or more digital certificates are country-specific and/or region-specific digital certificates. The region-specific digital certificate may be valid in multiple countries, such as a GSMA certificate.
Preferably, the two or more digital certificates comprise a GSMA (GSM association) certificate and/or a CTTL (China telecom Technology Labs) certificate. However, the present disclosure is not so limited and other digital certificates that may be used for communication in a mobile network may be provided.
Preferably, the selection module is configured to select one digital certificate from the two or more digital certificates based on geography and/or MNO (Managed Network Operations). For example, there is a specific certificate covering all MNOs for a certain country. While it is important for other countries in which MNO the customer has his account.
Preferably, the selection module is arranged to select one of the two or more digital certificates based on the location or geographical location of the communication module (i.e. based on geography) and/or based on the origin of the user or the eSIM profile of the user.
In some embodiments, the determination may be made based on the geographic location of the communication module or based on the geographic location of the user, e.g., a user boarding or using the vehicle: which digital certificate to use. For example, a user driving into a second country with a vehicle authorized in a first country may load an eSIM profile for the second country in order to save roaming charges. The certificate valid in the first country is replaced with a certificate valid in the second country according to the geographic location of the communication module, thereby enabling communication using the eSIM profile of the second country. In some implementations, the loading of the additional digital certificates can be automated, such as when a user loads an (additional or new) eSIM profile.
Additionally or alternatively, which digital certificate to use may be determined based on the source or country of the user, e.g., the user boarding or using the vehicle. For example, a user may have an eSIM profile for a first country. Then, the communication module uses a certificate valid in the first country to enable communication using the eSIM profile of the first country. The determination of the source or country of the user or eSIM profile can be accomplished, for example, through user input. For example, the user can select the country corresponding to their eSIM profile verbally and/or via manual input, such as manual input on a touch screen of the communications module or via a unit connected with the communications module. Alternatively, the source of the eSIM profile can be automatically identified, for example, by the eSIM module.
Preferably, the eSIM module is configured to load one or more eSIM profiles specific to a user. For example, the eSIM module can load a user-specific eSIM profile from an external server to enable personalized connectivity for the user. For example, a chinese user using a vehicle in germany may load his chinese eSIM profile in the vehicle and use it for communication.
Preferably, the selection module is arranged to check when the communication module crosses a border from a first country to a second country: whether the currently used digital certificate is valid in the second country. The selection module may be further configured to select another valid digital certificate from the two or more digital certificates when it is determined that the currently used digital certificate is not valid. For example, when crossing a boundary from a first country into a second country, a certificate (e.g., a CTTL certificate) valid in the first country is replaced with a certificate (e.g., a GSMA certificate) valid in the second country, thereby enabling communication using an eSIM profile of the second country.
Preferably, the communication module is configured to communicate according to LTE (Long-Term Evolution) standard and/or 5G standard. In particular, in some embodiments, the communication module of the vehicle is arranged for wireless communication in a mobile network, for example with a server or backend. Communication via other current or future communication technologies is possible. However, the present disclosure is not limited to mobile communication standards, and non-mobile communication standards may be used.
For example, the Communication module is a Wireless Communication device capable of communicating in a Mobile Network via a Local Area Network (LAN), such as a Wireless Local Area Network (WiFi/WLAN), or via a Wide Area Network (WAN), such as a Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS), Enhanced Data rate for Global Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), High Speed Downlink/Uplink Packet Access (High Speed Downlink/Uplink Packet Access, HSDPA/HSUPA), Long Term Evolution (Long-Term Evolution, LTE), 5G, or worldwide Interoperability for Microwave Access (max).
Preferably, the communication module is implemented in a vehicle or a mobile terminal. The term "vehicle" especially includes vehicles for passenger transport. The vehicle may be a vehicle (e.g., an automobile), a boat, or an aircraft (e.g., a jet for passenger traffic), but is not so limited. The term "vehicle" includes cars, vans, buses, motor homes, motorcycles, etc. for transporting people, goods, etc. In particular, the term includes motor vehicles used for passenger transport.
The term "mobile terminal" includes in particular smart phones, but also other mobile phones or handsets equipped with a device for communication technology, Personal Digital Assistants (PDAs), tablets, laptops, smartwatches and all current and future electronic devices.
According to another independent aspect of the present disclosure, a vehicle, in particular a vehicle, such as an automobile, is presented. The vehicle includes a communication module according to embodiments of the present disclosure.
According to another independent aspect of the present disclosure, a method for operating a communication module is presented. The method includes selecting one digital certificate from two or more digital certificates stored in a communication module according to circumstances; and communicating with the mobile network using the selected digital certificate and the eSIM profile.
The method may implement aspects of the communication module described in this document.
According to another independent aspect, a Software (SW) program is described. The software program can be arranged for execution on one or more processors and thereby perform the methods described in this document.
