Abstract: Disclosed is a method for transmitting data between a subscriber terminal (MT) and at least one service providing component (MMS-Server 1, MMS-Server 2, MMS-Server 3) associated with a service provider, which are connected to each other by a network (UTRAN, SGSN, GGSN). According to said method, when a communication link is set up between the subscriber terminal and the service providing component, access information for the at least one service providing component is requested by a storage means associated with the subscriber terminal. By providing exclusively specific access information for specific service providing components on said storage means associated with a subscriber or a subscriber device, such as a SIM card or a USIM application on a UICC card, the network operator can prevent a subscriber from using other service providing components of other specific service providers different from those prescribed thereto when a specific data service is requested.

Abstract: The disclosure relates to a remote query and remote maintenance of a communications module. To this end, the invention provides a method and device is provided for querying data by means of a data call between a service facility and a communications module over a communications network. A data query of a first interface unit sent by a service facility and received via the communications network is forwarded to another interface unit of a communications module, where the data query is interpreted in the interface unit and the interpretation result is evaluated by an evaluation unit. Response data for the data query is, based on the interpretation result from the evaluation unit, sent via the first interface unit to the service facility.

Abstract: Apparatuses and methods for transmitting control data on a physical channel between a mobile radio device and a base station in a cellular network. In particular, in a mobile radio network according to the UMTS standard (UMTS=Universal Mobile Telecommunication System) a packet-oriented data transmission between the mobile radio device and the base station is controlled using control data, wherein the control data includes a packet number for identifying a data packet.

Abstract: A method for logging a radio module into a cellular radio network, where the radio module automatically logs into the radio network when it is turned on by virtue of it transmitting a login message to the radio network, the radio network storing login data for the radio module and the login data being deleted again when the radio module logs out. In response to an autoreset signal in the radio a controlled autoreset is triggered in which the radio module temporarily turns off and then on again or temporally deactivates from the radio network and then registers again.

Abstract: A method for detecting a signal propagation time between a mobile radio terminal and a base station in a mobile radio network in a mobile radio terminal, particularly for the purpose of localizing the mobile radio terminal which inserts a propagation time detection information item into a channel request message in order to signal to the base station that no channel reservation is necessary, and that only the propagation time detection needs to be carried out, so as to achieve significantly reduced loading of network resources.

Abstract: The present disclosure relates to a circuit arrangement and a method for defining the signal direction in a data line between the interfaces of a SIM card and a GSM modem, without a control signal for the direction of data and without remote access. According to the disclosure, the transmission direction of the data signals is detected and as a result only one direction is permitted for the transmission, whilst detection in the opposite direction is simultaneously blocked.

Abstract: A system controllable by an external microcontroller via an interface external to the system includes a radio module, and a GPS receiver. The radio module is adapted to 1) pass messages received via the interface to the GPS receiver via an internal interface, and 2) to receive messages from the GPS receiver via an internal interface and pass them further to the external interface.
