Zusammenfassung:	When mobile data transmission occurs in a data network, a modification of an IP address in a lower protocol layer which, for example, uses the DCCP protocol supporting modification of the IP address in an existing data link, is indicated in relation to a higher protocol layer such that links existing in the higher protocol layer can be updated with the IP address. The higher protocol layer can include the SIP signaling protocol during a Voice-over-IP-voice communication application, for example, in addition to a real time data transmission protocol. Said SIP signaling protocol can update URI identifier and IP address assignment information when the address is modified.
