Abstract
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.
