Abstract: In order to establish a packet communication between a first server (SS) connected to a packet network (RP) and a service entity (ES) capable of communicating without a subscriber identification module in a radiocommunication network (RR), the service entity transmits an identifier (IdEs) of the service entity (ES) to a second server (SO) that determines an address (Ads) of the first server based on the received service entity identifier. The second server transmits the determined address of the first server to a gateway that interconnects the radiocommunication network and the packet network. The gateway establishes a communication between the service entity and the first server based on the address of the first server.
