Device and method for setting up a subsequent connection for data transmission via a mobile telecommunications system, after the termination of the first connection

1. A method 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 ), in which between the data transmitter ( 1 ) and the second data receiver ( 2 ′) or a first data receiver ( 2 ), a first call setup has already taken place within a certain time period Δt in the past, and wherein the data transmitter ( 1 ) has at least one memory device ( 10 ), and the mobile telecommunications system ( 3 ) has at least one air interface ( 30 ) and one controller device ( 31 ), 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 resource occupation and configuration of 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 can 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.

2. The method of claim 1 , wherein the resource occupation and configuration of the data transmitter ( 1 ) stored in the memory device ( 10 ) of the data transmitter ( 1 ) are stored in memory temporarily.

3. The method of claim 1 , resources that have just been released are not allocated by the controller device ( 31 ) until no other resources are available any longer.

4. The method of claim 1 , wherein the resources that are first allocated again by the controller device ( 31 ) are those whose release occurred longer ago.

5. The method of claim 1 , wherein an acknowledgment message ( 5 ) sent from the controller device ( 31 ) to the data transmitter ( 1 ) is acknowledged by the data transmitter to confirm a correct resource allocation.

6. The method of claim 1 , wherein the instant of callup of the resource occupation and configuration of the data transmitter ( 1 ), stared in the memory device ( 10 ) of the data transmitter ( 1 ), form new allocation thereof in the additional call setup is predetermined.

7. An 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 ), in which between the data transmitter ( 1 ) and the second data receiver ( 2 ′) or a first data receiver ( 2 ), a first call setup has already taken place within a certain time period Δt in the past, and wherein the data transmitter ( 1 ) has at least one memory device ( 10 ), and the mobile telecommunications system ( 3 ) has at least one air interface ( 30 ) and one controller device ( 31 ),

wherein the mobile telecommunications, system ( 3 ) has at least one controller device ( 31 ) for allocating resources of an air interface ( 30 ) to the data transmitter ( 1 ) and for constructing a certain configuration of the data transmitter ( 1 ) in the first call setup;

wherein the data transmitter ( 1 ) has at least one memory device ( 10 ) for storing the resource occupation and configuration of the data transmitter ( 1 ) of the first call setup in memory; and

wherein the mobile telecommunications system ( 3 ) has a transmitter ( 33 ) for sending an identification message ( 7 ) from the controller device ( 31 ) to the data transmitter ( 1 ) in the additional call setup for calling up the resource occupation and configuration, stored in the memory device ( 10 ), of the data transmitter ( 1 ) for a new allocation thereof in the additional call setup.

8. The apparatus of claim 7 , wherein the memory device ( 10 ) of the data transmitter ( 1 ) is embodied as a temporary memory device ( 10 ).

9. The apparatus of claim 7 , wherein the mobile telecommunications system ( 3 ) is embodied as a UMTS (Universal Mobile Telecommunication System) system.

10. The apparatus of claim 7 , wherein the data transmitter ( 1 ) is embodied as a mobile telephone ( 1 ).

11. The apparatus of claim 7 , wherein the resources, for instance in a UMTS (Universal Mobile Telecommunication System) system, are defined as a combination of a CDMA (Code Division Multiple Access) code, a carrier frequency, and optionally a time slot of a corresponding transmission channel.
