Abstract
Systems and methods according to these exemplary embodiments provide for selectively transmitting a pre-registration, re-registration or de-registration initiation message associated with handing off user equipment between different access systems, e.g., a long term evolution (LTE) system and a high rate packet data (HRPD) system, to reduce dormant sessions. The decision to selectively transmit initiation messages is typically performed by a dormant session management function (DSMF).
