Abstract
A method is provided for using a service of a mobile packet core network in a communication system comprising a mobile device, a node, a mobile packet core network and a wireless radio access network. The mobile device accesses the mobile packet core network via the wireless radio access network. During setup of a connection of the mobile device to the wireless radio access network, the mobile device determines whether the wireless radio access network is trustworthy. If it is not trustworthy, the mobile device establishes a secure tunnel connection to the node of the communication system for triggering usage of the service of communication system by an authentication entity. The secure tunnel connection is established by using a token stored within the mobile device and received by the node. The token comprises at least a certificate for authentication to the authentication entity and is generated using general security mechanisms (e.g., TPM and/or MD5).
