20130137429ACCESS CONTROL FAILURE HANDLING FOR HENB INBOUND MOBILITY - When MME receives Handover required from source eNB/HeNB which contains CSG ID, it verifies whether the CSG subscription data it stores is fresh or expired. If it is expired, or if MME does not have any association data for UE, MME retrieves the latest CSG subscription data from HSS. MME rewrites its stored CSG subscription data with the one retrieved from HSS, if they are different. MME performs access control for the UE according to the CSG ID received from Handover required message and its CSG subscription data. When the access control is failed, a new message List Update Indication is proposed to be sent from source eNB/HeNB to UE. In order to indicate what caused the failure, an appropriate cause in the message is proposed. Upon receiving the message, UE updates its stored CSG whitelist, such that the CSG subscription data in UE and MME are synchronized.05-30-2013
