TD S2 160192 23.402 CR2930 (Rel 14, 'B'): IMEI check for trusted WLAN access to EPC case. (Source: Alcatel-Lucent, Nokia Networks).
Abstract: Summary of change: Specify the procedure of IMEI check during the initial attach over trusted WLAN access:
- It is specified that the TWAN is the entity that triggers the IMEI check for a UE
- It is specified that additional TWAN-AAA server exchanges are necessary:
- The TWAN requests the AAA server to retrieve the IMEI(SV) from the UE, to perform IMEI check
towards the EIR and to follow the 'actions on IMEI check result' indication included in that request;
- The AAA server may provide the IMEI Check Result to the TWAN for e.g. statistics.
No need for changing 16.2.2 as it refers to 16.2.1 for these changes.
