S102: Determine a candidate cell according to a result of frequency point scanning and try to access;

S103: After the access cell succeeds, obtain data required for starting the station.

Specifically, the Relay can pre-store the frequency information supported by the operator according to the needs of the operator, and form a list of scanning frequency points. During the networking, the relay scans according to the pre-stored scanning frequency list and records the frequency scanning result, and then determines the candidate cell according to the frequency sweeping result and attempts to access, and obtains the version and configuration information after the access is successful to complete the opening. station.

In a specific implementation, the M cells with a large reference signal receiving power (RSRP) may be selected as the candidate cells for attempting access, and the access attempts are performed one by one until the access is successful. Or all the M cells try to access. Of course, the M cells may also be sorted according to the size of the RSRP to determine the priority of the attempted access, and then try to access according to the priority order.

It should be noted that, in the process of attempting to access, the base station where the candidate cell is located (ie, the candidate host macro station) checks and checks the EID of the accessed relay device. If the host macro station does not configure the EID, the The relay device cannot access the host macro station normally.

After the RN accesses the target cell successfully, the candidate cell (ie, the target cell) that receives the successful access is sent an OMC (Operation and Maintenance Center) link-building message, and the PnP (PluP) is triggered after the RN and the OMC are completed. -and-Play, Plug and Play policy, release version and configuration data or manual upgrade version or configuration data, RN starts the station.

If the cell cannot be accessed normally, the RN continues to try to access the next candidate cell until the access is successful or all candidate cells are tried. When all candidate cells fail to access, restart the device and perform frequency point scanning again.
