Step S401:RN is with UE identity core network access EPC (i.e. the first stage is accessed).RN is by the number now set up
Connect (PDN connection, Packet Data Network connection) according to network and access Internet, and join according to manufacturer
Put acquisition by its OAM serviced (oam system) server address, and set up service connection with this server.
After OAM carries out authentication to RN, according to locally stored information and RN now Location information, configure for RN
Necessary service data, such as RN allows host base station (DeNB) list accessed.
Step S402:RN, according to DeNB list obtained in step S401, selects the DeNB that can access.RN with
RRC successful connection is set up between DeNB, and during RRC connection establishment, during RN informs that DeNB access node is
Continue node.RN carries oneself in RRC signaling and asks (Attach Request) to the attachment of EPC (core net) simultaneously.
Step S403:DeNB configures according to the OAM of oneself, or is setting up during S1 mouth with the MME being connected
Obtain which MME and can support the information of via node function.DeNB, according to the information obtained in step S402, sentences
Determining institute's access node is via node, and selects to support the MME of via node function for this RN.DeNB is that this RN is to this
MME initiates special S1 and connects (UE associated S1 connection) Establishing process, asks to be transmitted to this by the attachment of RN
MME, and inform that this access node of MME is via node in the process.
The information that access node is via node that step S404:MME provides according to DeNB in step S403, needs this
Access node authenticates.Due to some reasons, such as: the network planning of renewal is no longer necessary to this RN and carries out the network coverage；Or
Person is out-of-date due to hardware or software, it is no longer necessary to use this RN.In the present embodiment, this RN is the most no longer allowed by network with relaying
Node mode runs, and this authenticating result confirms that access node does not possess via node authority.
Step S405:MME sends attachment rejection signaling (ATTACH REJECT), and (network being equivalent in embodiment 1 is even
Connect unsuccessfully instruction) to RN, indicating its state of RN in this signaling is not legal via node, such as by the spy in signaling
Determine EMM cause value (EMM Cause), or in this signaling, increase new cell.
After step S406:RN receives Attach Reject message, disconnect and being connected with the RRC between DeNB.And from this message
In know that self does not the most possess via node authority, it is therefore desirable in mode described in step S401, start again from the first stage
Access network, it is thus achieved that the configuration data of renewal.
Alternatively, after RN is successfully accessed OAM server, RN provides the reference information of config update, example to OAM
If send a warning message (WARNING) is to OAM, the instruction failed reason of RN access network is that MME thinks RN
State is no longer via node.
OAM is the more newly configured data of RN, such as software upgrading.If after data update, RN possesses via node power again
Limit, then can repeat the step after step S402, with via node identity access network.If after data update, RN is still
So do not possess via node authority, the most out of service.
The via node of the present embodiment is after second stage access failure, because failure cause is that self configuration does not possess via node power
Limit, it is thus determined that from first stage access network, cannot set up, with network, the problem being connected after solving the failure of RN access network,
