PACKET DATA NETWORK CONNECTION WITH NON-TRANSPARENT INTERWORKING MODE

摘要

An authentication request of a key information exchange mechanism used across an unsecure internet protocol network is received by a packet data gateway (20) from a user equipment (10). The authentication request includes a configuration parameter for a protocol configuration option which includes an information element of the protocol configuration option, in which authentication data according to an authentication protocol between the user equipment (10) and a packet data network (50) is encoded, wherein the authentication request is for authenticating the user equipment (10) by a communications network (40) providing connectivity for the user equipment (10). The information element is included into a binding update request which is sent to a gateway apparatus (30) for the packet data network (50).
