The present invention relates to an apparatus and method for releasing local data contents for an IP-based data access, wherein an evaluation unit () evaluates a first IP connection (IP-V) and extracts an IP destination address (IP:B) and an authorisation verification generating unit () generates an authorisation verification (BN) for the data access to the local storage unit (). An authorisation message generating unit () generates an authorisation message on the basis of the authorisation verification (BN) and the extracted IP destination address (IP:B). A trigger unit () triggers a transmission process of the generated authorisation message over a second IP connection (IP-V) which is different from the first IP connection (IP-V).

Apparatus and method for releasing local data contents for IP-based data access, associated communication system, digital storage medium, computer program product and computer program

In the novel method for data transmission via a radio interface in a radio communications system, at least two data channels are assigned to one connection. Each data channel can be distinguished by an individual spread code. In addition to data symbols, midambles with known symbols are transmitted in a data channel. The number of midambles being used for the connection is less than the number of data channels. The method is particularly suitable for use in TD/CDMA 3generation mobile radio networks.

Method and radio station for data transmission

In a wireless telecommunication system, for example a DECT/GAP system, under the control jurisdiction of a first telecommunication apparatus of the telecommunication system control mechanisms (i.e. messages, information elements and procedures) of a standard protocol (e.g. a protocol according to the DECT/GAP standard) are activated for the execution of a special protocol, which serve for the exchange of additional items of information between the first telecommunication apparatus and a second telecommunication apparatus of the telecommunication system.

Process and arrangement for executing protocols between telecommunications devices in wireless telecommunications systems

In a method for data transmission in a radio communications system, a radio interface is subdivided into time slots for a transmission of bursts. In this case, the data are transmitted in data channels in a time slot, in which data channels can be distinguished by use of individual spread codes. A finite burst containing data symbols and at least one midamble with known symbols is used for data transmission in a data channel. At least one parameter is determined for the traffic conditions of the radio interface, and a ratio of a length of the midamble and a data part with data symbols is adjusted depending on the traffic conditions. The method is suitable in particular for use in 3 generation TD/CDMA mobile radio networks.

In an antenna diversity base station of a DECT cordless telephone, at least one antenna change is carried out, for example on the basis of field strength measurements (FSM1, FSM2), in order to improve the &ldquo;antenna diversity&rdquo; during the reception of a DECT radio message, for example of a synchronization initiation word (E-SEW) of a synchronization field (SYF) to the DECT standard. As a result of the fact that the antenna change takes place during the reception of the synchronization initiation word (E-SEW), both optimum &ldquo;antenna diversity&rdquo; and interference-free transmission of wanted information contained in the radio message are possible in each transmission time slot of the DECT radio message.

Antenna diversity radio receiving arrangement for telecommunications systems using block-oriented transmission of radio messages

The radio area to be covered by the stationary radio transmission/reception device, for example of the base station of a cordless telephone, is illuminated by two or more directional antennas (,) respectively covering a radio sub-area thereof, whereby that respective directional antenna in whose radio sub-area the mobile radio transmission/reception means, i.e., for example, the mobile part of the cordless telephone, is located is activated (antenna diversity). The method and apparatus can be advantageously utilized in cordless telephones.
