1. A wireless communication device (WCD) for establishing a PPP data session between a user terminal (UT) and an Interworking Function (IWF), comprising:
- means for establishing a PPP2 link with the IWF in response to detecting a mobile IP data session request from the UT;
means for detecting a PPP1 link with the UT in response to the PPP2 link being established;
means for detecting that a PPP2 link failure has occurred; and
means for reconfiguring at least one of the WCD and the UT to an initial state.

Abstract
This disclosure describes techniques for establishing a PPP data session between a user terminal (UT) and an Interworking Function (IWF). The process involves establishing a PPP2 link with the IWF in response to detecting a mobile IP data session request from the UT, detecting a PPP1 link with the UT in response to the PPP2 link being established, detecting that a PPP2 link failure has occurred, and reconfiguring at least one of the WCD and the UT to an initial state.
