name: NNSF
full_form: NAS Node Selection Function
context: Target RNC sends the RANAP Enhanced Relocation Complete Request message to the SGSN, indicating that relocation is happened on the UE. 13. MSC configures the necessary Iu resources for the Target RNC and acknowledges with âRANAP Enhanced Relocation Complete Responseâ message to the Target RNC. In case ATM Transport option is deployed over Iu-CS UP, the MSC contains the Transport Layer Information in the message. After reception of the message in the Target RNC, the RNC initiates to establish AAL2 connection and executes Iu UP initialization. 14. SGSN configures the necessary Iu resources for the Target RNC and acknowledges with âRANAP Enhanced Relocation Complete Responseâ message to the Target RNC. 15. After completion of UP initialization, the Target RNC sends RANAP Enhanced Relocation Complete Confirm message to the MSC. 16. MSC initiates release of the resources in the source RNC by sending RANAP: Iu Release Command 17. SGSN initiates release of the resources in the source RNC by
description: The NAS Node Selection Function (NNSF) is a network function responsible for selecting the appropriate NAS node for a user equipment (UE) in a mobile communication network. It plays a crucial role in managing UE connections and mobility, particularly during radio interface paging operations.
explanation: Based on the context provided from 3GPP TS 25.413, NNSF is classified as a Network Function due to its involvement in selecting NAS nodes for UEs and influencing the behavior of RNCs during paging operations.
