Checking RNC Data
This describes how to check RNC data consistency and redundancy.
7.2.9.2.1 Rules of Data Consistency Check
This describes how to check data integrity of a single RNC or multiple RNCs and how to check data consistency on the radio network layer.
7.2.9.2.2 Checking RNC Data Consistency
This describes how to check RNC data integrity and how to check data consistency of the radio network layer. The inconsistent data can be loaded onto network elements and validated before the network elements start up and run properly.

7.2.9.2.4 Checking RNC Data Redundancy
The redundant data is physical bearer data that is obsolete. The redundancy check helps clear redundant data to lighten the load. It also helps you ensure that obsolete data is deleted after data modification.
?.1. Rules of Data Consistency Check
This describes how to check data integrity of a single RNC or multiple RNCs and how to check data consistency on the radio network layer.
The check items are as follows:
l Global location information
– LAC, RAC, URA, and SAC
l Basic information of the RNC – OSP
– Clock source and working mode – CN domain data
l Data of the transport network user plane and control plane on the Iub, Iur, Iu-CS, Iu-PS,
and Iu-BC interfaces
– NCP and CCP
– AAL2 adjacent node
– AAL2 path
– AAL2 route
– MTP3b signaling link set – MTP3b signaling link
– MTP3b route
– Physical link for carrying each of the SAAL link, IPoA PVC, an AAL2 path
– DSP of IUCS or IUCS_ALCAP type
l Cell data and neighboring relation at the radio network layer, including the consistency of
the cell parameters, cell names, NRNC IDs, and GSM cells and also the unidirectional or bidirectional neighboring relations Data to be checked is listed in Table 7-9.

Data Description
NRNC Cell l Check Existence of NRNCCELL: After the reparenting, the NRNC
cells configured by a third party may not exist on the NRNCs. In this case, the CME checks whether the involved RNCs exist and provides a wizard for changing the ownership of the NRNC cells. This wizard guides you to move the NRNC cells to other RNC and exports the modified MML script.
l Check CellNameConflict: The CME checks whether the names of the
cells and NRNC cells under the current RNC are in conflict with the names of the cells configured with the Iub interface under other RNCs. After the check, the CME provides a modification wizard and generates an MML script. To modify the name of a cell under an NRNC, you need to exit the current RNC and open the NRNC.
l Check Consistency of NRNCCELL: Based on the cell ID, the CME
checks whether the data of a cell under an RNC is consistent with the data of the same cell under another RNC. The data includes the cell name, frequency, and scrambling code. After the check, the CME provides a modification wizard and generates an MML script. If the frequency is changed, the CME can automatically adjust the neighboring relations between cells.
GSM Cell l Check GSMCELL Consistency: If the MCC, MNC, CID, and
LAC of each GSM cell configured on the local RNC are consistent with those configured on other RNCs, the CME checks the consistency of other data and displays the inconsistent data.
l Check GSMCELL Frequency: The CME checks whether the
frequency of a GSM cell in the current RNS adheres to the rules. The CME does not provide a modification wizard.
Data Description Neighborin
g Relations
l Check TwinCell Neighboring Reflexivity: The CME checks whether
the cells controlled by the same NodeB are configured with the bidirectional inter-frequency neighboring relations. Through the modification wizard, the user can delete the corresponding neighboring relation and export the modified MML script.
l Check Total Number of Intra and Inter Neighboring Links for
Each Cell: The CME checks whether the number of cells that are configured with intra-frequency and inter-frequency neighboring relations to a target cell exceeds the maximum value. The user can set the maximum value. Through the modification wizard, the user can delete the corresponding neighboring relation and export the modified MML script.
l Check Total Number of Intra Neighboring Links for Each Cell:
The CME checks whether the number of cells that are configured with intra-frequency neighboring relations to a target cell exceeds the maximum value. The user can set the maximum value. Through the modification wizard, the user can delete the corresponding neighboring relation and export the modified MML script.
l Check Total Number of Inter Neighboring Links for Each Cell:
The CME checks whether the number of cells that are configured with inter-frequency neighboring relations to a target cell exceeds the maximum value. The user can set the maximum value. Through the modification wizard, the user can delete the corresponding neighboring relation and export the modified MML script.
l Check Total Number of Intra Neighboring Links with Sib11 Usage
for Each Cell: When the SIB11 delivering indication (SIB11Ind) is set to TRUE, that is, when the neighboring relation is delivered in the SIB11, the CME checks whether the number of the intra-frequency neighboring relations configured for a target cell exceeds the maximum value. The user can set the maximum value. Through the modification wizard, the user can delete the corresponding neighboring relation and export the modified MML script.
l Check Total Number of Inter Neighboring Links with Sib11 Usage
for Each Cell: When the SIB11 delivering indication (SIB11Ind) is set to TRUE, that is, when the neighboring relation is delivered in the SIB11, the CME checks whether the number of the inter-frequency neighboring relations configured for a target cell exceeds the maximum value. The user can set the maximum value. Through the modification wizard, the user can delete the corresponding neighboring relation and export the modified MML script.
l Check Unidirectional Intra Neighboring Relations: The CME
checks the cells configured with the unidirectional intra-frequency neighboring relations. Through the modification wizard, the system automatically adjusts the neighboring relation to bidirectional neighboring relation. For the inconsistent parameter configuration between cells, the system adjustment is as follows:
–If the cell frequencies are inconsistent, the system adjusts the cell
frequencies based on the source cell frequency, and then determines 7 Operating the CME

Data Description
whether the frequency of the neighboring cells is the same as that of the current cell. If the frequencies are the same, the neighboring relation is not changed. If the frequencies are different, the system adjusts the neighboring relation to inter-frequency neighboring relation.
–If the parameters other than cell frequency are inconsistent, the
system adjusts the parameters based on the source cell parameters.
l Check Unidirectional Inter Neighboring Relations: The CME
checks the cells configured with the unidirectional inter-frequency neighboring relation. Through the modification wizard, the system automatically adjusts the neighboring relation to bidirectional neighboring relation. For the inconsistent parameter configuration between cells, the system adjustment is as follows:
–If the cell frequencies are inconsistent, the system adjusts the cell
frequencies based on the source cell frequency, and then determines whether the frequency of the neighboring cells is the same as that of the current cell. If the frequencies are different, the neighboring relation is not changed. If the frequencies are the same, the system adjusts the neighboring relation to intra-frequency neighboring relation.
–If the parameters other than cell frequency are inconsistent, the
system adjusts the parameters based on the source cell parameters.
