The value of tmnxWlanGwMgwProfSeHoldTime specifies, in seconds, the time that a GTP session context is held after the corresponding User Equipment is disconnected. If the same User Equipment reconnects to this system before this time has elapsed, its GTP session context is reused. When the timer expires, the GTP session context is cleared. The value minus one specifies that the timer is equal to the User Equipment's DHCP remaining lease time. The value zero specifies that the GTP session context is cleared immediately.
