This describes how to check the consistency between RNC data and NodeB data on the Iub interface. Data consistency is necessary to the normal communication between RNC and NodeB.
Prerequisite
l The Iub interface data is configured on the RNC side. l The Iub interface data is configured on the NodeB side.
Context
When the RNC and the NodeB are connected through a switching device, the features of the physical layer of the RNC can be inconsistent with those of the NodeB. In this case, you need to check the data consistency of only the data link layer and above. Note that the check should be performed from the top layer to the data link layer in the Iub protocol stack. For ATM transport mode, the check items include NCP, CCP, ALCAP, AAL2Path, IPoA, FRAATM, IMA, and UNI. For IP transport mode, the check items include NCP, CCP, IPPath, OMIP, PPP, MLPPP, EtherIP, and IPRT. Table 7-6 and Table 7-7 describe the check rules.

Item Rule
NCP/CCP l The CCP port number and link quantity configured on the RNC must be
consistency with those configured on the NodeB.
l For the same NCP and the same CCP, the following parameters must be
consistent on the two ends: ServiceType, PCR, SCR, MCR, MBS (maximum burst size), CCTM (CC timer), POLLTM (POLL timer), IDLETM (IDLE timer), NRTM (NO_RESPONSE timer), KATM (KEEP_ALIVE timer), MaxCC (maximum number of retransmissions upon expiration of the connection control timer), MaxPD (maximum number of PDUs that can be transmitted during a polling period), MaxSTATLE (maximum length of the STAT PDU list), VPI, VCI, and CarrierType.
ALCAP l If the ownership attribute of the ATM address of the adjacent node on the
RNC is set to yes, that is, this adjacent node is directly connected to the RNC, then this ATM address must be consistent with that on the NodeB. Otherwise, such consistency is not required.
l For the same NodeB, the following parameters must be consistent on the
two ends: NSAP, ServiceType, PCR, SCR, MCR, MBS, CCTM, POLLTM, IDLETM, NRTM, KATM, MaxCC, MaxPD, MaxSTATLE, VPI, VCI, and CarrierType.
AAL2PAT H
l The number of AAL2 paths must be consistent on the two ends.
l For the same path, the following parameters must be consistent on the two
ends: ServiceType, PCR, SCR, MCR, MBS, CDVT (cell delay variation tolerance), VPI, VCI, and CarrierType.

IPoA l The local IP address on the RNC must be consistent with the peer IP address
on the NodeB. The peer IP address on the RNC must be consistent with that on the NodeB.
l The following parameters must be consistent on the two ends: ServiceType,
PCR, SCR, MCR, MBS, CDVT, VPI, VCI, and CarrierType.
IMA Group The following parameters must be consistent on the two ends: IMALinkNum (number of links, IMAVer (IMA protocol version), TxFrameLength, and MinActiveLinks.
FRAATM TimeSlotNum (number of E1/T1 timeslots) must be consistent on the two ends.
UNI -
Optical port -
Others The physical link bearers must be consistent on the two ends. Here is a counterexample. On the RNC side, the NCP and CCP0 are carried on R_UNI1 and the CCP1 and CCP2 are carried on R_UNI2; on the NodeB side, however, the NCP and CCP1 are carried on N_UNI1 and the CCP0 and CCP2 are carried on N_UNI2.

Item Rule
NCP/CCP l The number of CCP ports must be consistent on the two ends.
l For the same port, the local SCTP address on the NodeB must be consistent
with one of the destination SCTP addresses on the RNC; the destination SCTP address on the NodeB must be consistent with one of the local SCTP addresses on the RNC.
IPPath l The number of IP paths must be consistent on the two ends.
l For the same path, the local IP address on the RNC must be consistent with
the peer IP address on the NodeB; the peer IP address on the RNC must be consistent with that on the NodeB.
l The path type, physical link type, TX bandwidth, and RX bandwidth must
be consistent on the two ends.
OMIP The local IP address on the RNC must be consistent with the peer IP address on the NodeB. The peer IP address on the RNC must be consistent with that on the NodeB.

Item Rule
PPP l The local IP address on the RNC must be consistent with the peer IP address
on the NodeB. The peer IP address on the RNC must be consistent with that on the NodeB.
l TimeSlotNum (number of timeslots) must be consistent on the two ends. l The following parameters must be consistent on the two ends: IPHC (IP
header compression), MRU (maximum receive unit), and RestartTimer. MP l The local IP address on the RNC must be consistent with the peer IP address
on the NodeB. The peer IP address on the RNC must be consistent with that on the NodeB.
l The number of PPP links must be consistent on the two ends. l IPHC must be consistent on the two ends.
EtherIP No consistency is required for the IP address and route data on the two ends. PPPoE No consistency is required. The NodeB side uses the PPPoE mode while the
RNC uses the Ethernet mode.
Procedure
Step 1 Click in the CME configuration object pane, and then click NodeB CM Express in the configuration task pane. The NodeB CM Express window is displayed.
Step 2 Click . The Physical NodeB Basic Information window is displayed.
Step 3 Select a NodeB to be checked from the right pane, and then click . The NodeB Selection dialog box is displayed.
Step 4 ClickFilter,TheSelect NodeB dialog box is displayed.
(Optional) You can also click Load to select NodeBs by loading a user-defined file in the Select NodeB window. For details, refer to 7.3.7 Managing Hot NodeBs and Cells.
Step 5 Select a NodeB from the resource poor, click Add or double-click the NodeB, and then click Close. The information of the NodeB is displayed in the NodeB Selection dialog box. Step 6 click Next. The Compare Result dialog box is displayed.
Step 7 The dialog box displays the number of NodeBs on which the Iub interface data is inconsistent with that on the RNC. Click Details to view the details, as shown in Figure 7-28.
