Abstract
The application relates to the integration of WLAN access networks into cellular communication networks, often referred to as “Non-3GPP Access” in 3GPP standardization, in particular TS 23.402. Location information, such as SSID, WLAN access point name, WLAN access point identifier, WLAN access point MAC address is currently not available for GTP based S2a nor GTP based S2b, and neither for the Gn interface nor for PMIPv6 based S2a. However, Location information is needed in the PGW/GGSN for multiple purposes, e.g. for policy enforcement, charging and lawful interception. This problem is solved by the application in that the missing information is included in a protocol message of the cellular communications system, in particular a GTPv1, GTPv2 or PMIPv6 signalling message, and communicated (S2) to the cellular communications system. Furthermore, an event trigger, similar to event triggers on the Gx interface which may be set by the PCRF, may be set by the PCRF/OCS in the WLAN (S4, S5) to request up-to-date location information (S6, S7, S8).
