Provided are improved systems, methods, devices, and computer program products for optimized access network authentication of an access terminal on an access network supporting negotiation of an application level protocol for the air link or implementing access network authentication functionality with an extended packet-oriented RLP. A packet-oriented air link application layer protocol supporting the functionality of CHAP authentication, such as an application level authentication protocol operating on an HRPD EvDO Rev A access network or an extended packet-oriented RLP operating on an enhanced HRPD EvDO Rev A access network, can be used for authenticating an access terminal on the access network without setting up a PPP session for access network authentication, such as setting up a PPP session with the SC/MM network entity by doing LCP and CHAP just to do terminal authentication using the protocols of the PPP protocol suite. Embodiments of the present invention avoid the need for setting up a PPP session for access network authentication, thus, saving air link resources and time during the authentication process for the access terminal and access network and reducing the complexity of access terminal implementations by avoiding the need for multiple PPP sessions.
