PPP LINK NEGOTIATION IN MOBILE IP SYSTEMS

摘要

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 PP1 link with the UT in response to the PP2 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.
