[0001] The present invention relates to a method for conducting an emergency communication and / or for configuring an emergency communication, the emergency communication using an in-vehicle system in a country, or a geographic region within a country, that is part of the coverage area of a mobile communication network.

[0002] Furthermore, the present invention relates to an in-vehicle system for conducting an emergency communication and / or for configuring an emergency communication, the emergency communication using an in-vehicle system in a country, or a geographic region within a country, that is part of the coverage area of a mobile communication network.

[0003] Additionally, the present invention relates to a system or a mobile communication network for conducting an emergency communication and / or for configuring an emergency communication, the emergency communication using an in-vehicle system in a country, or a geographic region within a country, that is part of the coverage area of a mobile communication network.

[0004] Furthermore, the present invention relates to a program and to a computer-readable medium for conducting an emergency communication and / or for configuring an emergency communication according to the inventive method.

[0005] Emergency communications, or emergency calls, are an established tool to provide help in case of emergencies.

[0006] However, in currently known implementations, the integration of new features and / or the realization of flexible solutions typically requires substantial efforts and / or is time-consuming, especially implementations that are flexible to implement in an adaptable manner (especially based on the same technical infrastructure and / or based on the same components in a manner such that the same components (or components having the same configuration) are able to be used, i.e. using identical parts in order to realize an increased number of pieces), e.g. in a manner such that implementations are able to differ between different geographical regions.SUMMARY

[0007] An object of the present invention is to provide a technically simple, effective and cost effective solution for conducting an emergency communication and / or for configuring an emergency communication in a flexible manner. A further object of the present invention is to provide a corresponding in-vehicle system, a corresponding system or mobile communication network, and a corresponding program and computer-readable medium.

[0008] The object of the present invention is achieved by a method for conducting an emergency communication and / or for configuring an emergency communication, the emergency communication using an in-vehicle system in a country, or a geographic region within a country, that is part of the coverage area of a mobile communication network,wherein the in-vehicle system comprises a terminal equipment entity or functionality as well as a mobile termination entity or functionality, wherein, regarding conducting and / or configuring emergency communication, at least one piece of emergency communication information (or at least one emergency communication-related parameter) is stored in the in-vehicle system and / or at least one action is requested, by the terminal equipment entity or functionality, from the mobile termination entity or functionality,wherein the method comprises the following steps:-- in a first step, the terminal equipment entity or functionality requests the at least one piece of emergency communication information (or at least one emergency communication-related parameter) and / or requests at least one action by means of an emergency communication request,-- in a second step, the terminal equipment entity or functionality receives the at least one piece of emergency communication information (or the at least one emergency communication-related parameter) and / or the mobile termination entity or functionality conducts the at least one requested action.

[0009] It is thereby advantageously possible, according to the present invention, to use AT-commands (or application programming interface messages or commands) for conducting emergency communication, especially eCalls, and especially for configuring emergency communication in an (or by an) in-vehicle system (IVS) - such as eCalls, test eCalls, but also calls to, e.g., service centers that are not (or might not be), technically speaking, emergency calls in the strict sense but are nevertheless initiated by the in-vehicle system that is used, typically in a vehicle, for emergency communication -, wherein such emergency communication, or its configuration, involves managing communication between the vehicle's telematics system and emergency services, ensuring secure, robust and reliable transmission of critical data. Integrating AT-commands (or application programming interface functionality) into the eCall system for in-vehicle systems (IVS) provides several benefits over relying solely on the traditional protocol-based eCall specifications.

[0010] Especially, according to the present invention and by means of integrating, or using, AT-commands and / or application programming interface functionality, it is advantageously possible to realize a higher level of scalability and interoperability with the components of the in-vehicle system, especially with the universal integrated circuit card or functionality (IIICC - hereinafter also called IISIM). It is to be understood that - in the context of the present invention - an embedded subscriber identity module (eSIM) is, alternatively, likewise meant (and is synonymously used) to the terms universal integrated circuit card or functionality or IISIM (card).By means of using these AT-commands (or application programming interface functionality) it is advantageously possible to provide a flexible solution that allows for updates and the integration of new features, standards, or technologies without necessitating a complete system overhaul. This is particularly important given current challenges, such as the phase-out of 2G technology, which affects legacy fleet vehicles. Additionally, this especially enables a flexible implementation in a manner such that different configurations might apply to different (geographical) regions and where, depending on respective (potentially different) regulation, a different behavior results in a specific profile in regions (as it is required there) - e.g. a different behavior, and thus different configurations, of in-vehicle systems used in Europe (e.g. the Ell), the USA and / or China.It is furthermore advantageously possible according to the present invention that AT-commands (or application programming interface functionality) are used to facilitate the incorporation of advanced functionalities like satellite fallback, mesh networking, and predictive analytics. The use of AT-commands and / or of application programming interface functionality also facilitates the management of connections across various network types and technologies, thereby enhancing the system's ability to operate on a global scale and across different network standards. Especially, this flexibility allows an improved system resilience and scalability as well as specific eCall system implementations to be more easily integrated with other digital ecosystems; furthermore,it is advantageously possible, according to the present invention, to more easily and / or more flexibly conduct emergency communication test calls such as test eCalls.

[0011] Hence, according to the present invention, it is advantageously possible to enhance the capabilities and / or the configurability of in-vehicle systems beyond the traditional eCall specifications, thereby improving system resilience and scalability.Especially according to the present invention, the following enhancements and / or functions are proposed:-- a new function to cover the specific behavior of regional regulatory requirements - for example, requirements defined for profiling in-vehicle systems for the European (or Ell) market;-- a new function that the in-vehicle system shall remain registered (if not in limitedservice state) and shall wait for a potential PSAP (public safety answering point) callback for a specific time);-- a new function that the in-vehicle system shall continue the NG (next generation) eCall but shall not resend the minimum set of data if the in-vehicle system receives a SIP 200 OK response containing a negative minimum set of data acknowledgement message (MSD ACK);-- a new function for support of MSD reception by a PSAP using in-band modem over packet switched networks; requirements that the IVS shall set up an IMS emergency voice call (without MSD transfer and without use of eCall URNs) if no eCall supported cell is available;-- a new function that the IVS shall continue the NG eCall as a normal IMS emergency voice call but shall not resend the MSD if eCall support of cell changed during call;-- a new function that the IVS shall try to reattempt the NG eCall for a period of up to 2 minutes if 1st attempt fails;-- a new function that the IVS shall try to reattempt the NG eCall for a period of up to 2 minutes, if eCall drops after successful eCall establishment.According to the present invention, the related and required parameters can be stored on the universal integrated circuit card or functionality or IISIM by operator or car manufacturer respectively the in-vehicle system manufacturer. By means of AT-commands, The in-vehicle system application can query these parameters and use them for eCall establishment.The proposed new procedures give the flexibility to provide and update eCall profiles by eligible authorities eg. NRAs or PSAP for eCall and test-eCall depending on regulatory requirements for regional markets.

[0012] Especially, the present invention proposes to enable these requirements by new commands of the AT interface, but implementation can be also applied by a new API-based interface (optional with a combination / addition to AT commands) between the in-vehicle system application and the modem.

[0035] The present invention will be described with respect to particular embodiments and with reference to certain drawings, but the invention is not limited thereto but only by the claims. The drawings described are only schematic and are nonlimiting. In the drawings, the size of some of the elements may be exaggerated and not drawn on scale for illustrative purposes.

[0037] Furthermore, the terms first, second, third and the like in the description and in the claims are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.

[0038] In Figure 1, a telecommunications network 100, especially a mobile communication network 100, is schematically shown. The mobile communication network 100 comprises an access network 110 and a core network 120, and an in-vehicle system 20 is connected to the mobile communication network 100 via the access network 110. The mobile communication network 100 is especially realized as a mobile (cellular) communication network 100, and the access network 110 of the mobile communication network 100 exemplary comprises a plurality of radio cells 11, 12. In the exemplarysituation or scenario shown in Figure 1 , a first base station entity 111 generates or is associated with or spans the first radio cell 11, and a second base station entity 112 generates or is associated with or spans the second radio cell 12. In the exemplary situation shown in Figure 1, the in-vehicle system 20 - if connected to or with the mobile communication network 100 - is connected, via a radio interface or air interface, to the first base station entity 111 of the access network 110 of the mobile communication network 100.In case of an emergency situation, a call is initiated, by the in-vehicle system 20, to an instance such as a service provider 200 or a public safety answering point 180.Optionally, it might be the case that an emergency communication is initiated, from the service provider 200 and in dependency of the location of the in-vehicle system 20, to the specific public safety answering point 180.

[0039] In Figure 1, the in-vehicle system 20 (or also called user equipment 20) is schematically shown as comprising different components: According to the present invention, the in-vehicle system 20 comprises a terminal equipment entity or functionality 21 as well as a mobile termination entity or functionality 23. In the exemplary embodiment shown in Figure 1, the user equipment 20 additionally comprises a terminal adaptor entity or functionality 22.

[0040] Figure 2 shows the in-vehicle system 20 and its components in greater detail, namely the terminal equipment entity or functionality 21 , and the mobile termination entity or functionality 23. Again, in the exemplary embodiment shown in Figure 2, the user equipment 20 additionally comprises the terminal adaptor entity or functionality 22.More generally according to the present invention, the terminal equipment entity or functionality 21 is able to request, by means of a first request 522, a first requested information 521. According to the exemplary embodiment represented in Figure 2, the terminal equipment entity or functionality 21 transmits the first request 522 to the terminal adaptor entity or functionality 22, and receives the first requested information 521 from the terminal adaptor entity or functionality 22. Furthermore in the exemplary embodiment shown in Figure 2, the terminal adaptor entity or functionality 22 is able to request, by means of a second request 524 and especially to the mobile termination entity or functionality 23, a second requested information 523.Between the mobile termination entity or functionality 23 (of the in-vehicle system 20) and the network 100 (exemplarily, in Figure 2, the mobile communication network 100 is considered to be the HPLMN of the in-vehicle system 20), a number of network messages 230 are typically exchanged.According to the present invention, the terminal adaptor entity or functionality 22, or “TA"- Terminal Adaptor, is especially a phone data card supporting 2G, 3G, 4G, 5G and / or 6G (equal to a DCE; data circuit terminating equipment), and / or the terminal equipment entity or functionality 21, or “TE" - Terminal Equipment, is especially a computer (equal to DTE; data terminal equipment), or, in case of an eCall, the in-vehicle system device it would be the actual application executed in the device.

[0041] According to the present invention, it is advantageously possible and preferred, that the first request 522 (or the corresponding message, i.e. a first request message 522) corresponds to an emergency communication request 522 in the form of AT-commands. Hence, between on the one hand the terminal equipment entity or functionality 21, and on the other hand the terminal adaptor entity or functionality 22 or the mobile termination entity or functionality 23, an AT-command interface is realized. Alternatively (or cumulatively to realizing such an AT-command interface), it is advantageously possible and preferred, that the first request 522 (or the corresponding message, i.e. a first request message 522) corresponds to an emergency communication request 522 in the form of an application programming interface request. Hence, between on the one hand the terminal equipment entity or functionality 21 , and on the other hand the terminal adaptor entity or functionality 22 or the mobile termination entity or functionality 23, an application programming interface is realized.The first requested information 521 (or, the corresponding message, especially comprising this information) corresponds to the respective response or responses of the first request message 522.The second request 524 (or second request message 524) corresponds to mobile termination control commands (typically according to a proprietary interface of the manufacturer of the terminal adaptor entity or functionality 22 and / or of the mobile termination entity or functionality 23); the second requested information 523 (conveying or comprising the first requested information 521) especially corresponds to a mobile termination status message.Hence especially, an AT-command interface or an application programming interface (or, more generally, a terminal equipment-terminal adaptor interface) is used between, on the one hand, the terminal equipment entity or functionality 21, and, on the other hand, the terminal adaptor entity or functionality 22 or the mobile termination entity or functionality 23, thereby allowing an application (or an application-level entity or functionality of the terminal equipment entity or functionality 21 , i.e. of the in-vehicle system 20) to become aware of the at least one piece of emergency communication information (or the at least one emergency communication-related parameter). Alternatively or cumulatively thereto (i.e. to become aware of the at least one piece of emergency communication informationor the at least one emergency communication-related parameter), the application (or an application-level entity or functionality of the terminal equipment entity or functionality 21, i.e. of the in-vehicle system 20) the terminal equipment entity or functionality 21 is able to request (by means of the first request message 522, and again using a AT-command or an application programming interface) at least one action from the mobile termination entity or functionality 23.

[0042] It is preferred according to the present invention that the AT-command interface (and / or the application programming interface) is realized either between the terminal equipment entity or functionality 21 and the terminal adaptor entity or functionality 22, or between the terminal equipment entity or functionality 21 and the mobile termination entity or functionality 23.Especially when an AT-command interface (or application programming interface) is used, a command towards the mobile termination entity or functionality is comparatively easily able to be generated, based on the terminal equipment entity or functionality’s knowledge of the at least one piece of emergency communication information (or the at least one emergency communication-related parameter), e.g. by settings of the in-vehicle system application. In the exemplary embodiment shown in Figure 2, the terminal adaptor entity or functionality 22 receives the first request (message) 522 from the terminal equipment entity or functionality 21 (especially triggered by a user interaction and / or an event of an application 211 of the terminal equipment entity or functionality 21), and the terminal adaptor entity or functionality 22 transmits the requested information 521 to the terminal equipment entity or functionality 21.

[0043] According to the present invention, it is especially advantageous and preferred that, as on option, interactions with a SIM card (i.e. a subscriber identity module card - which term is used synonymously with the term universal integrated circuit card or functionality (IIICC)) can be used to store / query parameters and the required architecture can be described as represented in Figure 3.Thus, Figure 3 schematically represents an example of a communication within the in-vehicle system 20 in case of using a universal integrated circuit card or functionality 24 as part of the in-vehicle system 20; i.e. Figure 3 shows the communication between the terminal equipment entity or functionality 21 , the terminal adaptor entity or functionality 22, the mobile termination entity or functionality 23, and the universal integrated circuit card or functionality 24. A double arrow between the terminal equipment entity or functionality 21 and the terminal adaptor entity or functionality 22 schematically and exemplarily either indicates the AT-command interface or the application programming interface, and another double arrow between the mobile termination entity or functionality23 and the universal integrated circuit card or functionality 24 schematically and exemplarily indicates the mobile termination entity or functionality - universal integrated circuit card or functionality interface.

[0044] In order to allow an application (i.e. the terminal equipment entity or functionality 21) to request at least one action and / or to query an emergency communication information (or an emergency communication-related parameter) - which emergency communication information (or which emergency communication-related parameter) being especially (but not necessarily) stored on the subscriber identity module or subscriber identity module (SIM) card or universal integrated circuit card or functionality 24 and / or especially being remotely maintained by, e.g., the home operator on the subscriber identity module or sim card (or universal integrated circuit card or functionality) a respective command set for the “AT(-command) interface” (or application programming interface) and / or for the “MT-UICC” interface and respective procedures needs to be defined. Hence, e.g., in order to allow an application (i.e. the terminal equipment entity or functionality 21) to trigger / store / query, for example, eCall parameters from the mobile termination entity or functionality 23 or from the universal integrated circuit card or functionality 24 (e.g. URNs, MSD mode, retry, fallback) only a command set for the “AT interface” as well as for the “MT-UICC” interface and respective procedures needs to be defined.
