A method and device for providing a communication or chat session with a plurality of users, in particular for mobile radio networks according to Global System for Mobile communication (GSM) or Universal Mobile Telecommunications System (UMTS) standards. A first user starts a General Packet Radio Service (GPRS) session requesting an Internet Protocol (IP) address at the network. The first user then sends an initiation message including the IP address to a plurality of other users which preferably are selected from a mobile station's telephone book. Addressed users also request IP addresses at the respective networks and send a reply including the respective IP address via GPRS to the first user. After receiving at least one reply, the first user activates a chat session and all participants can exchange messages, preferably text and images, via GPRS or another packet switched service.

What is claimed is: 1. A method for providing short message service chat sessions with at least a first, second and third user of a communications system including at least a first, second and third terminal assigned thereto, respectively, said second and third terminals forming at least part of a group of terminals, comprising: generating a list of selected users for each short message service chat session; transmitting an initiation message for a short message service chat session from said first terminal to said group of terminals, said initiation message including a first address assigned to said first terminal; dividing a display of said first terminal to simultaneously display text to be transmitted from said first terminal and text received from a terminal of said group of terminals, said dividing based on if there is text to be transmitted by said first terminal; receiving said initiation message at said second terminal and said third terminal of said group of terminals; transmitting a first reply to said initiation message from said second terminal of said group of terminals to said first terminal; receiving said first reply at said first terminal; transmitting a second reply to said initiation message from said third terminal to said first terminal; receiving said second reply at said first terminal; said first terminal marking said second and third terminals as active; activating said short message service chat session; creating a list of active terminals of said communication session; transmitting said list of active terminals to at least one of said second and third terminals; and after said activating, employing said first terminal as a server for said communication short message service chat session to store messages of said short message service chat session or assign said messages to terminals assigned to participants of said short message service chat session, wherein said first terminal can transfer responsibility as said server to said second or third terminal. 2. The method as recited in claim 1 wherein said first reply includes a second address assigned to said second terminal. 3. The method as recited in claim 2 wherein at least one of said first address and said second address is a packet data protocol address. 4. The method as recited in claim 2 wherein at least one of said first address and second address is an Internet Protocol address. 5. The method as recited in claim 1 further comprising requesting said first address by said first terminal prior to transmitting said initiation message. 6. The method as recited in claim 2 further comprising requesting said second address by said second terminal prior to transmitting said first reply. 7. The method as recited in claim 1 wherein said transmitting said initiation message is performed in conjunction with a circuit switched service. 8. The method as recited in claim 1 wherein said transmitting said first reply is performed in conjunction with a packet switched service. 9. The method as recited in claim 1 wherein said transmitting said first reply is performed in conjunction with a General Packet Radio Service. 10. The method as recited in claim 1 wherein said transmitting said first reply is performed in conjunction with using an Internet Protocol. 11. The method as recited in claim 1 wherein at least one of said first terminal and said second terminal is selected from the group consisting of: a mobile station, a mobile phone, a wirebound terminal, a wirebound phone, and a computer. 12. The method as recited in claim 1 wherein said communications system includes a network selected from the group consisting of: a Global System for Mobile Communication, and a Universal Mobile Telecommunications system. 13. The method as recited in claim 1 wherein at least one of said first and said second terminals enable at least one of said first and said second users to input data and said data is exchanged at least between said first and second terminals with a packet switched service after receiving said first reply at said first terminal. 14. The method as recited in claim 1 wherein said first address is requested at a stationary part of said communication system or, if said first terminal already has an existing address, using said existing address as said first address. 15. The method as recited in claim 14 further comprising selectively enabling at least one of said second and third users to input data and transmitting said data to each active terminal with a packet switched service. 16. A method for transmitting a circuit switched message from a first terminal assigned to a first user of a communications system to second and third terminals having second and third users, respectively, comprising: providing via said first terminal an input by said first user for said circuit switched message; defining a group of users including said second and third users; generating and transmitting a list of selected terminals for each short message service chat session including said second and third terminals; selecting a subscriber number for said second and third terminals; transmitting said message to said second and third terminals; employing said first terminal as a server for short message service chat session messages between said first, second and third terminals, wherein said first terminal can transfer responsibility as said server to said second or third terminal; and dividing a display of said first terminal to simultaneously display text to be transmitted from said first terminal and text received from another terminal, said dividing based on if there is text to be transmitted by said first terminal. 17. The method as recited in claim 16 wherein at least one of said subscriber numbers is a mobile subscriber number selected from a data base in said first terminal, said first terminal being a mobile station and said message being transmitted with short message service. 18. A mobile device for use with a communications system including said mobile device, a second terminal and a third terminal, comprising: means for storing an initiator address; means for transmitting an initiation message for a text chat session to receiving terminals wherein said initiation message includes said initiator address; means for receiving a reply message from at least one of said receiving terminals, means to activate said text chat session based on said reply message; means for dividing a display of said mobile device to simultaneously display text to be transmitted from said mobile device and text received from another device of said communications system, said dividing based on if there is text to be transmitted by said mobile device; and means to function as a server for said text chat session after said text chat session is activated, wherein said mobile device includes means to transfer responsibility as said server to said second or third terminal. 19. A device as recited in claim 18 further comprising means to transfer said function as said server to said at least one of said receiving terminals. 20. A device as recited in claim 18 further comprising means for storing a packet data protocol address and means for transmitting a packet data protocol address. 21. The device as recited in claim 18 further comprising means for storing an Internet Protocol address and means for transmitting an Internet Protocol address. 22. The device as recited in claim 18 further comprising means for requesting an address at said communications system. 23. The device as recited in claim 18 further comprising means for communicating an initiation message with a circuit switched service. 24.
