Abstract:
1. An apparatus for executing end to end authentication in a network environment, comprising: a mobile terminal operable to initiate a communications tunnel with a layer two tunnel protocol (L2TP) network server (LNS) and to communicate an activate context request that includes an authentication protocol in a protocol configuration option (PCO) field, the activate context request being received by a gateway general packet radio service (GPRS) support node (GGSN) that initiates a link control protocol (LCP) negotiation with the LNS, the GGSN being operable to communicate an activate context response that may be received by the mobile terminal, the mobile terminal being further operable to calculate an authentication response by using a secret value and a challenge value which is provided by the GGSN, the authentication response being used to establish a communication session associated with the mobile terminal.
