Abstract

The invention relates to a method for exchanging messages (NAR) among the users (C, D, E, F) of at least one chat group (GR1) of a telecommunication system (SYS), according to which at least one chat message (NAR) from a mobile radio device (TE1-TE4) associated with one user (C, D, E, F) of a chat group (GR1) is transmitted to a chat service center (SER) via at least one telecommunication network (NET). Said chat service center forwards the chat message (NAR) via tie at least one telecommunication network (NET) to a mobile radio device (TE1-TE4) of at least one further user (C, D, E, F) of the chat group (GR1).

Claims

1. A method for exchanging messages between participants, of at least one chat group of a telecommunication system, comprising:

transmitting a chat message from a mobile terminal assigned to a participant of a chat group via at least one message transmission network to a chat service center; and

forwarding the chat message via the at least one message transmission network to a mobile terminal of at least one further participant of the chat group.

2. The method in accordance with claim 1, wherein a command to create the chat group is entered via the mobile radio terminal of a participant and is transferred to the chat service center which creates and administers the chat group in response thereto.

3. The method in accordance with claim 1, wherein a participant logs in using a respective mobile radio terminal via the chat service center to the chat group.

4. The method in accordance with claim 1, wherein the chat message is forwarded from the chat service center to the mobile radio terminal of the at least one further participant depending on a geographical position of the mobile radio terminal.

5. The method in accordance with claim 1, wherein, when a participant logs on to the chat group the chat service center determines whether participation in the chat group is dependent on the geographical position of the participant.

6. The method in accordance claim 1, wherein the at least one chat message is forwarded to further participants who are located within a specifiable area around the participant sending out the chat message.

7. The method in accordance with claim 6, wherein the chat group is assigned to the specifiable geographical region.

8. The method in accordance with claim 7, wherein the chat group is assigned to a specifiable topic.

9. The method in accordance with claim 1, wherein, on request, the chat service center filters out chat messages dealing with a specifiable subject and submits them to at least one participant of the chat group.

10. The method in accordance with claim 1, wherein the chat message is transferred as a voice message.

11. The method in accordance with claim 1, wherein the chat message is transferred as a text message.

12. The method in accordance with claim 1, wherein at least one message transmission network is a UMTS network.

13. The method in accordance with claim 1, wherein at least one message transmission network is a GSM network.

14. The method in accordance with claim 1, wherein the chat message is transferred as an SMS message.

15. The method in accordance with claim 1, wherein at least one message transmission network is the Internet.

16. The method in accordance with claim 15, wherein the chat message is transmitted in accordance with a Voice-over-IP protocol.

17. A telecommunication system, which is set up for exchange of messages between participants of at least one chat groups comprising:

a mobile radio terminal assigned to a chat group transmitting at least one chat message from a participant of the mobile radio terminal via at least one message transmission network to a chat service center, in which the chat service center is set up to forward the chat message via the at least one message transmission network to the mobile radio terminal of at least one further participant of the chat group.

18. The telecommunication system in accordance with claim 17, wherein the system is configured to accept a command for creation of the chat group via the mobile radio terminal of a participant and to transfer the command to the chat service center which is configured to create and administer the chat group.

19. The telecommunication system in accordance with claim 17, wherein the chat service center is configured to accept log in of the participant to the chat group via the mobile radio terminal assigned to the participant.

20. The telecommunication system in accordance with claim 17, wherein the chat service center is configured to forward the chat message depending on a geographical position of the mobile terminal of the at least one further participant.

21. The telecommunication system in accordance with claim 17, wherein the chat service center is configured so that when a participant logs in to the chat group it determines whether participation in the chat group depends on the geographical position of the participant.

22. The telecommunication system in accordance with one of the claims 17, wherein the chat service center is configured to forward the at least one chat message to a further participant located within a specifiable area around the participant sending out the chat message.
