METHOD OF COMMUNICATING BETWEEN A WIRELESS TERMINAL AND A PACKET DATA NETWORK

摘要

A wireless terminal, such as a 3GPP UE, transmits a first message of an Internet key exchange (IKE) protocol to a node of a packet core network for initiating a first authentication procedure between the UE and a first server associated with the packet core network. The outcome of the first authentication procedure is received by the UE which transmits a second IKE message to the packet core node. The outcome of a second authentication procedure between the UE and a second server associated with an external packet data network is finally received by the UE. One of the above-mentioned first and second IKE messages (or both) conveys a protocol configuration options information element including authentication parameters for the second authentication procedure.
