Value Analysis and Application Cases-1/3 Values:
The OSS network is established first, which integrates the network management and the operations (network design/configuration, problem settlement, commissioning, and maintenance). The network reconstruction is avoided. The work efficiency is improved because no engineer is required to stay in the BSC equipment room for a long time to cooperate in the separate deployments.
The requirements for the skills of the commissioning engineers are reduced; therefore, the human resources allocation is flexible. The insufficiency of the engineers with higher technical skills is solved to meet the requirements of the delivery. The commissioning progress is accelerated and the project delivery becomes quicker. The commissioning costs are reduced, providing the prerequisite for reducing the costs of cooperation quotations.
Case 1: In the Reliance CDMA project in India, some regions adopt the remote commissioning mode.
Compared with the traditional commissioning mode, the human resources requirement is reduced by 30%. Engineers are not required to work in different BSC offices; therefore, a large amount of time and cost are reduced.

Value Analysis and Application Cases-2/3 Case 2: In the project of China Mobile Qinghai Branch, one equipment room (2 BSCs + 100
BTSs) adopts the remote centralized commissioning mode. Compared with the traditional commissioning mode, the requirement for high-end engineers is reduced by 50%. On the BSCs performed with centralized design and centralized data configuration, the network modification is less, while the work allocation is clearer.

Value Analysis and Application Cases-3/3 Case 3:
In the Reliance GSM project in India, the remote commissioning mode is adopted. Compared
with the local commissioning mode, the human resources requirement is reduced by 50%.
The engineers can deploy BTSs in the remote and centralized mode. The Engineers are not
required to work in different BSC equipment rooms for a long time; therefore, a large amount
of time and cost are reduced. Experience: There are about five types of simplified BTS configuration. The BSC data and BTS data script are
delivered to the remote engineers of each Circle, and then delivered to the onsite engineers
after some modification for the software installation and data loading. The A/Abis/Ater interfaces adopt the optical transmission, greatly reducing the connection error
probability in the hardware installation. For the internal cabling of the cabinet, the cabling
drawing is printed for the sub-contractors. Generally, if they operates based on the drawing, no
mistake will be made. The customer's preparation for transmission is made slowly. Separate deployments of BTSs are
conducted. The remote engineers can work in the maintenance room.Service Quantity

Flow SupportUnique difference with earlier projects: The OSS network is established first. Establish the OSS network first: When the remote commissioning mode is adopted, after
the BSC equipment hardware installation and before the software commissioning, the OM
channel is required, which connects the network management center and the BSC
equipment room. In this way, the engineers can remotely control the BAM and perform
commissioning on the BSS. (The M2000 may be established or not.) Before the equipment promotion, prepare the following guides and documents to support
the service implementation.

customer
In the main plan of the project in the bidding stage: Add the contents of the
OSS network to be established first. When the bidding is successful, the TD
discuss with the customer about the establishment of the OSS network in
the implementation plan. Advantages: The commissioning time is reduced. The customer can
perform centralized management on the network. It is the practice of the
industry. (In the project of Ericsson, the OSS network is established first.)

FAQ-1
Can the remote commissioning mode reduce
costs? Is it necessary?Q
A
1. By establishing the OSS network first, the centralized network design and
operation management and unified network data planning are realized;
therefore, the rework and reconstruction due to unreasonable data configuration
can be reduced.
2. The network adjustment parameters and precautions can be executed
uniformly, avoiding the interaction in scattering commissioning mode and
solving the problem that scattering deployment of BTSs takes too much time.
3. The human resources, especially the high-end engineers, can be allocated flexibly, thus dividing the human resources into different levels.
4. The centralized commissioning does not require the engineers to travel among multiple BSC offices to provide instructions.

FAQ-2
Is there any communication problem in the
cooperation between the remote and local
engineers in the remote commissioning mode?
Q
A1. Generally, there is no communication problem with the local
staff.
2. The network management has information collection capability
and can help locate the problem.
3. In the overseas project, the local staff who are trained with priority can be allocated to the network management. The language communication problem can be solved.
4. The local engineers have the STEP by STEP guides for reference, which can solve these problems to some extent.
HUAWEI TECHNOLOGIES CO., LTD. Page 12Huawei Confidential
FAQ-3
Is there any problem in the interconnection
data negotiation when the local end engineers
communicate with the customer in the remote
commissioning mode?
Q
A 1. Generally, the interconnection data will be negotiated by
the regional TD, remote engineers, and the customer.
2. Other problems can be negotiated by the local end
engineers and the customer. The BSC onsite engineers have
the basic skills.
HUAWEI TECHNOLOGIES CO., LTD. Page 13Huawei Confidential
FAQ-4
The remote commissioning mode requires less
human resources. Is there any problem in the
cutover during which more human resources
are required?
Q
A1. In the network transfer scenario, multiple BTSs controlled by a
BSC are transferred at the same time. The project team must have
designated mobile workforce to handle the problems in the network
transfer. In this case, the human resources requirement can be meet
by borrowing the engineers from other regions. - In normal cutover,
there are similar problems.
2. In the new deployment scenario, the BTSs are added gradually, so there is no risk.
HUAWEI TECHNOLOGIES CO., LTD. Page 14Huawei Confidential
FAQ-5When the OSS network is being established, the customer needs to borrow the transmission cables to establish the network management. How to solve the problem if the customer does not agree to borrow the transmission cables in advance?
Q
A
1. Describe the advantages of establishing the OSS network first in the whole
project to the customer with the typical applications.
2. On the stand of the customer, describe the advantages of establishing the OSS
network first for monitoring the whole project.
3. Explain to the customer that this mode is the practice of the industry. (In the
project of Ericsson, the OSS network is established first.) If the mode is
described in the implementation plan for the bidding, explain this plan to the
customer.4. If the GSM BSC6000 adopts the remote TC configuration and the
OSS is not established yet, after the BSC operates normally, the BSC remote
engineer can configure the remote maintenance channel and connect the Ethernet
port on the SCU board of the remote TC to the remote GOMU. Then A interface
connection is realized and the BTS data can be configured. For details, contact
Yan Jinping (44371).

FAQ-6
The OSS network hardware is provided, but the IP planning of the customer is not completed for use. How to solve the problem?
Q
A
Overall solution: Firstly, find the reason why the IP planning is not
completed. Secondly, determine the means to stimulate the IP
planning based on the relationship with the customer.
1. If the customer is a new operator who lacks the skills to perform the IP planning or has many other things to do, when we make the IP planning with the customer, we can provide the draft and then submit it to the customer for approval.
2. If the customer intentionally delays the IP planning and is unwilling to make the IP planning, we need to discuss with the service manager or the customer manager, and take measures to push forward the IP planning.

FAQ-7
Experiences in establishing the OSS maintenance networkQ
A
1. Apply for an IP address segment from the customer. The data communication engineers plan the IP address of each router and BSC. If the routers and switches are old devices or are provided by the customer, urge the customer to provide the usable switch ports.If the customer rejects the request, ask the onsite data communication engineers to assist the customer in providing the switch ports.Explain the reasons of establishing the OSS maintenance network first for the customer. The OSS network can monitor the BSCs and train the customer during the commissioning process to facilitate the Huawei engineers to locate the problem remotely.2. If the routers and switches are newly deployed and provided by Huawei, apply for the E1 transmission links used by the OSS maintenance network in advance, confirm the positions of the routers and switches and the power supply ports in advance (check whether the routers and switches use 220 V or -48 V power supply), clarify the structure of Huawei BSC maintenance network, provide the types of the routers, switches, and E1 interface cards of the routers, ask the data communication engineers to provide the configuration scripts of the routers and switches, and instruct the engineers to load the scripts to the routers and switches.
