Abstract: A network including a user equipment for accessing at least one of wireless local area network interworking services and third generation partnership project network services. The network also includes at least one third generation partnership project network for providing the third generation partnership project network services to the user equipment. The network further includes an access network for connecting the user equipment to the third generation partnership project network and for providing the wireless local area network interworking services. During network authentication, the user equipment provides a network access identifier including wireless local area network scenario information and an impostor is prevented from modifying the network access identifier during a response from the user equipment to the at least one third generation partnership project network implementing an authentication mechanism.

Abstract: The invention proposes a method for generating a subscriber identifier, comprising the steps of generating an identifier base string based on encrypting a subscriber identifying value, generating an integrity check value based on the identifier base string, and generating a subscriber identifier based on a concatenation of the identifier base string and the integrity check value. The invention also proposes a corresponding network control node.
