Abstract

At least one part of at least two user connections (TA1 . . . 6) having configured performance criteria and being allocated to at least two network devices (LE1 . . . 3) is assigned to at least one group (NWHG), to which group-specific performance criteria and/or characteristics (PDN, HUNT) can be allocated. The group (NWHG) is controlled by one of the network devices (LE1), whereby the user connections (TA1, 3, 4, 6) which have not been physically allocated to this network device (LE1) are allocated to said device as virtual user connections.
