Abstract

A user equipment establishes an elevated priority data connection and one or more non-elevated priority data connections. The elevated priority data connection may be an emergency public data network (PDN) connection. The user equipment may determine that one or more deactivation criteria for the emergency PDN connection is satisfied while the emergency PDN connection and at least one non-emergency PDN connection of the user equipment are active. Deactivation criteria may include expiration of a Periodic Tracking Area Update timer. In response, the user equipment may locally deactivate the emergency PDN connection and send a deactivation indication to the operator network.
