Abstract:

A user equipment (UE) establishes a unicast link with a second UE, including establishing an authentication and security establishment procedure between the first UE and the second UE. The UE establishes a security context with the second UE during the authentication and security establishment procedure. The UE starts a timer based on a status of the unicast link. The UE reestablishes the unicast link with the second UE using the security context when the unicast link is reestablished prior to expiration of the timer.
