Embodiment Construction
[0023] In the embodiments described below, the components of the circuit configuration structure are separate and can be regarded as independent features of the present invention. The features can continue to improve the present invention independently of each other and then simultaneously or separately Combinations different from those shown are regarded as constituent parts of the present invention. In addition, the described embodiments can also be supplemented by other features of the invention already described.
[0024] The figure shows a mobile communication device 10, which can be connected to a control processor 14 via one or more communication lines 12, and the control processor is connected to one or more (not shown) via the mobile communication device 10, for example, via a network. The mobile communication network exchanges voice data for telephone calls and other digital user data. The control processor 14 may be, for example, a control processor of an infotainment...

The invention relates to a circuit arrangement for mobile communications unit (10) of a motor vehicle, comprising: a first mobile communications module (18) for a mobile communications transmission according to a first mobile communications standard, a second mobile communications module (20) for a mobile communications transmission according to a second mobile communications standard and a reading unit (34) for reading identification data from a chip card (36). A reliable mobile communications connection should be made possible using cost-effective circuitry-related means, both for telephony and for the transmission of other digital data by means of control devices and personal computers. For this purpose, the circuit arrangement is configured to operate the two mobile communications modules (18, 20) at the same time, and the reading unit (34) is configured for the simultaneous operation of the two mobile communications modules to receive identification data from two subscriber identification modules (38, 40) from the same chip card (36) and to transmit the identification data of a respective subscriber identification module (38, 40) to one of the two mobile communications modules (18, 20).
Description
Technical field [0001] The present invention relates to a circuit configuration structure of a mobile communication device for automobiles. The circuit configuration structure has two mobile communication modules, and mobile communication transmission according to a predetermined mobile communication standard is realized respectively through the mobile communication modules. The circuit configuration structure also includes a reading device for reading identification data from the chip card. In the present invention, the chip card is understood as UICC (Universal integrated circuit card). Another expression of this UICC is the SIM card (SIM-Subscriber Identifcation Module). The present invention also relates to a method for operating a mobile communication device having the circuit configuration structure and to a UICC, that is, a chip card, in which a subscriber identification module (SIM) is integrated. Background technique [0002] A mobile communication unit (Mobile Equipm...
