Section: 5.3.5B MT-EDT procedure for User Plane CIoT EPS Optimisation
Content: Figure 5.3.5B-1: MT-EDT procedure for User Plane CIoT EPS Optimization 1. Same as step 1 in clause 5.3.4.3. 2. Same as step 2 in clause 5.3.4.3, with the following addition:; The Serving-GW may send the downlink data size to the MME for MT-EDT consideration if the downlink data is applicable for User Plane CIoT EPS Optimisation and MT-EDT is applicable for this PDN connection. 3. Same as step 3 in clause 5.3.4.3, with the following addition; If MT-EDT is applicable for the PDN Connection, the MME may include the downlink data size in the Paging message to assist eNodeB to use MT-EDT. 4. Same as step 4 in cluse 5.3.4.3, with the following addition; If data size is included in Paging message from MME, the eNodeB may decide to use MT-EDT, by adding a MT-EDT indication in the Paging message to the UE. 5-8. Follow the procedure as defined in clause 7.3b.3 in TS 36.300[ Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 ]  [5]. 9. SGW delivers downlink data to RAN. 10-11. The eNodeB can decide to use MT-EDT and move the UE to IDLE mode.
