1. A method for re-synchronizing a PPP link, comprising:
- detecting a trigger indicating whether a remote station is associated with a new base station;
determining whether the new base station is associated with a new network server; and
re-synchronizating the PPP link if the remote station is associated with the new network server.

Abstract
A method and system that provides for efficient re-synchronization of a PPP link on a Um interface is provided. When the PPP link is connected, if an indication that the communications of the mobile station is associated with a new network server is detected, only the Um interface will undergo PPP configuration renegotiation. The method and system does not require the examination of all data packets for determining whether PPP configuration renegotiation is required.
