Abstract: The invention creates a method for bidirectional data transmission of a data set between a data transmission device (1) and a data reception device (7) via at least one packet-oriented network device (3), in which connection-oriented switching is done, having the following steps: allocation of a data encapsulation protocol (10) to the data set to be transmitted connection-oriented in the data transmission device (1) or an external data terminal device (6) that is connected to the data transmission device (1), for an encapsulation of the data set to enable a connection-oriented data transmission of the data set; connection-oriented transmission of the encapsulated data set by means of at least one telecommunications device (4) from the data transmission device (1) to the packet-oriented network device (3); evaluation of the data encapsulation protocol (10) in the packet-oriented network device (3) for an unpacking of the data set to enable a packet-oriented data transmission of the data set; and packet-oriente

Abstract: The invention creates a method and a corresponding apparatus for an additional call setup for data transmission between a second data receiver 2′ and a data transmitter 1 via at least one mobile telecommunications system 3, having the following steps: allocation of resources of the air interface 30 to the data transmitter 1, and construction of a certain configuration of the data transmitter 1 by means of the controller device 31 in the first call setup; storing the 10 resource occupation and configuring the data transmitter 1 of the first call setup in the memory device 10 of the data transmitter 1; and sending an identification message 7 from the controller device 31 to the data transmitter 1 in the additional call setup, to call up the resource occupation and configuration of the data transmitter 1, stored in the memory device 10, for a new allocation thereof in the additional call setup.

Abstract: The present invention provides a detection method in which a CDMA-coded data signal is transmitted in the form of a data stream of spread data bursts between a transmitter and a receiver, hierarchical CDMA codes being used for the transmission. In a first step, codes having a smaller spreading factor than a maximally to be detected spreading factor (SF) are detected. In a second step, codes having a larger spreading factor than in the previous step are detected, the detection results of the first step being taken into account. In a third step, the detection process is broken off if all codes are detected, or otherwise the second step is repeated with the detection results last obtained in each instance, until all codes are detected.
