FIELD: physics; communication.
SUBSTANCE: invention relates to a method for supporting connection for data transfer with a terminal device when changing over from a first communication access network (WLAN) to at least, one second communication access network (PS). The terminal device for the same open user identifier of the terminal device is assigned at least two personal user identifiers and at least, two IP-addresses. The terminal device is registered in the communication IP-network in parallel for each communication access network using, respectively, the personal user identifier and the open user identifier and the IP-address for the first (WLAN) and at least one second communication access network (PS).
EFFECT: more efficient connection support.
