MAINTENANCE OF DATA CONNECTIONS DURING THE CHANGEOVER OF A COMMUNICATION ACCESS NETWORK

摘要

The invention relates to a method for maintaining at least one data connection to a terminal (UE) during the changeover of a first communication access network (WLAN) to at least one second communication access network (PS). According to the invention, at least two private user identities and at least two IP addresses are allocated to the terminal (UE) in order to form a public user identity for the user of the terminal (UE). The terminal registers itself in an IP communication network in parallel per communication access network respectively comprising one private user identity and the common public user identity, and an IP address for the first (WLAN) and the at least one second communication access network (PS).
