TRUSTED USER LOCATION INFORMATION FOR USERS ACCESSING A TRUSTED DOMAIN VIA AN UN-TRUSTED NETWORK

摘要

In a trusted domain of a cellular communication system reliable information regarding the location of a user equipment is required for services. In case the user equipment does not access the trusted domain via a 3GPP network the user location information is provided in addition to private access network information by a corresponding service located within the trusted domain. Said user location information is appended to messages by a proxy for further processing in the trusted domain. Said user location information is removed from any message leaving the trusted domain.
