WiFi offload: Non-seamless offload

Already used today, but ANDSF allows operator todecide what traffic to offloadOffloaded traffic becomes normal IP traffic via WiFi

Access network change means change in the IPaddress non-seamless

Initial 3GPP efforts have focused on the ability todifferentiate machine-type devices This allows the operator to selectively handle such devices

in overload situations

Radio-level optimisations to enable implementationof low-cost LTE M2M devicesWork moving towards generic solutions due to

divergence of M2M traffic patterns UE power consumption optimisation Optimisation for small data transmission
