Deactivation
Feature Changes
MME Initiated Notifications to HSS – Removed
Previous Behavior: When a UE moves from a LTE network to a WLAN network, MME receives a delete bearer
request from PGW. MME initiates a notification request to HSS to delete the bearer information. Due to deletion of the
bearer information from the HSS, the UE will not be able to connect to the same PGW when it switches back to LTE
from a WLAN network.
request from PGW. MME initiates a notification request to HSS to delete the bearer information. Due to deletion of the
bearer information from the HSS, the UE will not be able to connect to the same PGW when it switches back to LTE
from a WLAN network.
New Behavior: The MME is modified to not initiate notification requests to HSS, when a delete bearer request is
received from the PGW, during UE network switch. With this modified behavior, the UE can switch between LTE and
WLAN networks being connected to the same PGW.
