Step S202, the message informing MME that eNB is RN access by this access.ENB can, by carry RN attribute information in initial UE information (Initial UE Message) message, send the notice of this time access for the message of RN access to MME.For how carrying RN attribute information, the present invention also provides following two kinds of modes, for example,
Mode one, can represent by the RRC Establishment cause field increase RN-Access in initial UE informational message, according to this field, MME can know that this time access is for RN access.Particularly, the present invention has also proposed the mode that RRC Establishment Cause is revised, as follows:
RRC Establishment Cause
| IE/Group Name | Presence | Range | IE type and reference | Semantics description |
| RRC Establishment Cause | M | ENUMERATED (emergency, highPriorityAccess, mt-Access, mo-Signalling, mo-Data, RN-Access...) // expansion RN access |
Mode two, can increase RN field newly in the S1AP protocol message in initial UE informational message, and according to this field, MME can know that this time access is for RN access.Particularly, for the modification of INITIALUE MESSAGE as F:
INITIAL UE MES SAGE
| IE/Group Name | Presence | Range | IEtype and reference | Semantics description | Criticality | Assigned Criticality |
| Message Type | M | 9.2.1.1 | YES | ignore | ||
| eNB UES1AP ID | M | 9.2.3.4 | YES | reject | ||
| NAS-PDU | M | 9.2.3.5 | YES | reject | ||
