name: MTC-IWF
full_form: MTC Interworking Function
context: information for UE, such that UE does not need to contain MTC-IWF identifier in the Small Data. The detail is depicted in figure 5.7.4.4.4.3.2-1 given below Figure 5.7.4.4.4.3.2-1: MO Small Data Transmission 1. UE uses the subkeys to integrity and confidentiality (if necessary) protect the Small Data. 2. UE sends Small Data in Service Request to MME, with SCS ID. 3. MME can skip NAS integrity check, if the message type is small data. 4. MME retrieves the routing for UE and finds out to which MTC-IWF the Small Data should be sent. 5. MME forwards the Small Data to MTC-IWF. 6. MTC-IWF performs integrity check with its subkey and performs UE authorization, to see if the UE is allowed to send Small Data towards the given SCS. 7. MTC-IWF can also detect if there are too many small data being sent to the same SCS. 8. If the verifications in Step 6 and 7 are successful, MTC-IWF delivers the Small Data to SCS. 9. If the verifications in Step 6 and 7 failed, MTC-IWF can inform MME/eNB by
description: The MTC Interworking Function (MTC-IWF) is responsible for handling Machine-Type Communications (MTC) small data transmissions. It performs integrity checks, UE authorization, and detects potential issues with small data being sent to the same SCS. If verifications are successful, it delivers the Small Data to the Server and Charging System (SCS).
explanation: The MTC-IWF is classified as a Network Function because it performs specific tasks within the telecommunications network related to managing and processing MTC small data transmissions. It interacts with other network elements like MME and SCS, demonstrating its role as a functional component.
