1.6 Principles for RNC Integration

1. Integrate the control plane first, and then the user plane.

2. Integrate the control plane and the user plane in the bottom-up order on the protocol

stack.



1.7 Preparation for RNC Integration

1.7.1 Check of Hardware

1. RNC has been installed and powered on, and is running normally.

2. RNC has been connected with the interfaces involved in the integration physically.

3. NodeB has been installed and powered on, and is running normally.

1.7.2 Check of Data Configuration

1. Related integration parameters have been obtained and data configuration of RNC

has finished.

2. Data configuration of NodeB has finished.

1.8 Parameter Conversion Related with RNC

Integration

1.8.1 SPC Conversion

SPC provided by the operator is usually in the format: X-Y (X stands for SSF, and Y

stands for SPC), and the SPC mode (14 bit or 24 bit) will also be specified. When

configure data, we should convert Y into a decimal coding. If the SPC mode is 14 bit, we

will convert it into 3-8-3 mode; if it is 24 bit, we will convert it to 8-8-8 mode.

For example: In the RNC integration of Yanji Unicom in Jilin province, the SPC of

Ericsson’s MGW is 3-2052 (14 bit), which means SSF=3, SPC=2052, and the SPC mode

is 24 bit.

1. SSF has 2 bits, and its value is between 0-3. The meaning of each value is shown in

Table 1-2.

Table 1-2 The Meaning of Each SSF Value

SSF Value Stands for

00 International network

01 Spare (for international use only)

10 National network

11 Reserved for national use



From the above table, if SSF=3, SPC is reserved for national use.

2. The SPC mode is 14 bit, so it should be converted to 3-8-3 mode.

3. SPC=2052, which is a hexadecimal coding. We should convert it to a binary digit

first which is 10000001010010, and then according to the 3-8-3 mode, divide it to

001-00000000-100 (If there are less than three digits at the first part, add 0). Finally,

convert each segment into decimal number; the result is 1.0.4.

1.8.2 ATM Address Conversion

ATM takes the address formats as follows.

The commonly used format is E164 at present.

ZTE’s M31 supports E164 and NSAP formats, and NASP is the default one.

For example:

If the RNC ATM address provided by the operator is in E164 format: 070320000000000,

then we need to convert it to the NSAP format.

The AFI of the E614 format is 45, which is a hexadecimal number. Put it before

070320000000000, we can get 45070320000000000. And then divide it at two-digit

interval from left to right. If the last segment has only one digit, put an F at the end, for

example 45.07.03.20.00.00.00.00.0F. Finally, convert each two-digit segment into a

decimal number. The result is the ATM address in NSAP format, which is

69.07.03.32.00.00.00.00.15.

1.8.3 PVC Bandwidth Unit Conversion

Usually the bandwidth unit is cps at the CN side, and ZTE uses kpbs in data configuration

at the RNC side. The ATM cell has 53 bytes, therefore 1 cps = 1*53*8 bps = 424 bps =

0.424 Kbps.



2 NodeB Integration

Knowledge

Understanding the way of integration at the control plane of the Iub interface.

Learning about the integration of the radio cells.

Being familiar with the OMCB integration in different bearer mode.

2.1.2 Iub Integration Description

Follow the bottom-up order on the protocol stack to integrate the physical layer, IMA layer,

ATM layer and NABP layer in turn.

2.1.3 Physical Layer

1. Check the status of E1 subunit, and query the E1 subunit status of the

corresponding DTB at the RNC side.

To query the state, right-click DTB on the rack figure, select Show Board

Properties Pages > Subunit Configuration > Subunit Detail > State

information > State Query.

If the availability Status and the HW Status are both normal, the subunit status is

normal. If they are abnormal, please check whether there’s any problem with the

DTB board, whether E1 is connected properly, and whether DIP and jumper are

normal.



Figure 2-1 E1 subunit status

2. Check E1 L1-L32 on the DTB panel. If the E1 LED indicators are flashing slowly at 1

HZ, all the E1 links are normal.

3. Check the status of all the E1 lines at the NodeB side, and make sure these E1 links

have been added to corresponding IMA group in the configuration at the NodeB side

and the Status is Normal.

Figure 2-2 E1 status at NodeB side

2.1.4 IMA Layer

1. Check the status of the corresponding IMA E1 link in the RNC.



To query the state, click RNC ManagedElement(P) > RNC configuration

centralized management > Dynamic data management object > IMA link.

In the normal status, both Local terminal and Remote terminal of all the IMA E1

links are in the Active state.

Figure 2-3 IMA link status

2. Check the status of the corresponding IMA group in the RNC


centralized management > Dynamic data management object > IMA group.

If the Local state and the Remote state are both Running, the status of this IMA

group is normal. If it is abnormal, check whether the configuration of the integration

parameters of the two IMA groups, for instance, the scrambling and descrambling

configuration, are consistent.



Figure 2-4 IMA group status

2.1.5 ATM Layer

1. Check the status of corresponding PVC in the RNC. The status at Root side and

Branch side should be both normal.

To query the status, click RNC ManagedElement(P) > RNC configuration

centralized management > Dynamic data management object > PVC.



Figure 2-5 PVC status

2. Check the status of corresponding AAL2 in the RNC. The Administrative status

should be Unblock, the Local Block Status and the Remote Block Status should

be both Not Congested, and the Path Resetting Status should be No.


centralized management > Dynamic data management object > AAL2 PATH.



Figure 2-6 AAL2 status

3. For the AAL5 of non-OMCB type, trace SSCOP at the transport network SAAL layer.

In the normal state, there should be SSCOP keep-alive POLL and STAT messages

sent and received between the RNC and the NodeB.

Figure 2-7 SSCOP keep-active signaling

4. For the AAL5 of OMCB type, ping the NodeB operation and maintenance address

on the OMCB server. In the normal state, the link between the OMCB and the

NodeB should be able to be established.

2.1.6 NBAP Layer

1. Query NCP and CCP status of the corresponding NodeB in the RNC.




centralized management > Dynamic data management object > NodeB port.

In the normal status, the Administrative State is Unlock, the Operational Status

is Enabled, and the Availability Status of CCP is Normal, the Availability Status

of NCP is unavailable.

Figure 2-8 NCP and CCP status

2. Check the status of cells under the corresponding NodeB in the RNC.


centralized management > Dynamic data management object > Cell and

Channel..

In the normal status, the Administrative State is Unlock, the Existing State is

Existing, and the Availability Status is Normal.



Figure 2-9 Cells status

3. Log in to the NodeB from the DMS to check whether the common transport

2.2 ATM over STM-1

2.2.1 Iub Interface Integration Parameters

ATM over STM-1 and ATM over E1 are two different transmission bearer modes.

Therefore, as to integration, they mainly differ from each other in the integration of the

transport layer, while the integrations of the other protocol layers of the two bearer modes

are the same. The basic integration parameters of ATM over STM-1 are shown in Table

2-2.

APBE and that of the corresponding APBE board at the RNC side.

APBE/2 has only one subunit.

APBE has four subunits.

In the normal state, the subunit Availability Status and the HW Status should both

be normal.

In the normal state, the Administrative Status should be Unblock, the Local

Block Status and Remote Block Status should be Not Congestion, and the Path

resetting Status should be No. If multi AAL2 links are configured, you should block

them one by one to make a call test.

Figure 3-8 Office route query

3. The status of adjacent office signaling point can also be queried by tracing the

signaling of the MTP3B layer in the RNC. In the normal state, you can see the RNC

send the SLTM message, the MGW reply with the SLTA message, and the MGW

send the SLTM message, the RNC replies with the SLTA message. That means the

transmission at the MTP3B layer is unblocked, and the adjacent office signaling

point is reachable.
