Huawei's Self-Improving OSS

Introduction: At the MWC 2014, Huawei announced that it would provide customers with its commercial OSS solution, an act widely interpreted by industry analysts as Huawei Carrier BG's shifting focus to software and service. Faced with fierce competition, what differentiated solution can Huawei offer to telcos? And what unique value can Huawei bring for them?

As a managed services (MS) solution, Huawei's operations support

system (OSS) solution has long been serving the telecom industry.

Huawei has developed a set of mature products and telecom value

assets thanks to network O&M experience gained from hundreds of

global MS projects. Huawei's OSS asset library is completely decoupled

from products. It is independently developed, offered, and deployed, and

can interoperate with OSS products from other vendors.

Huawei's OSS solution matches customers' business process, offering

the following key benefits:

01

Resource Management Facilitates Service Provisioning

Huawei has over 500 service and resource model templates that

can manage network elements (NEs) on RAN, core/IP/transmission

networks. These model templates create physical and logical models

to realize time-based resource management, providing detailed

information on sites, areas, and links. The model templates can

also work in collaboration with the resource management system to

coordinate E2E network activities, including real-time planning, accurate

project implementation, automatic network service provisioning and

maintenance, network standards support, and evolution to the IP-based

network. Huawei's service and resource model templates can help

customers align resource planning with service provisioning and realize

automatic service provisioning.

02

Fault Management Improves Customer Service Efficiency

Huawei's OSS solution includes service packages encapsulated

with over 700 rules, including the intermittent alarm rule, parent-child

associate rule, delayed alarm rule, and automatic ticket dispatch rule,

enabling automatic cross-vendor and cross-field alarm processing. With

a unified interface and window, the fault processing system can realize

unified alarm management. Integrated with the resource management

system, the fault processing system can also conduct topology-based

root cause analysis. Huawei's rich alarm-related asset packages ensure

an E2E alarm consolidation rate of 99.9%.

Automatic TT Management

Huawei is in possession of over 30 types of network O&M process

assets. The Managed Service Unified Platform (MSUP) covers

10 processes including preventive maintenance, troubleshooting,

network change, and site handover, while event management, change

management, problem management, and request management are

processes of the Information Technology Infrastructure Library (ITIL).

Huawei's network O&M process assets drive all TT processing activities,

achieving automatic and visualized network O&M, as well as unified

ICT O&M. So far, Huawei has successfully helped carrier X of Indonesia

improve customer service efficiency by 46%, saving US$ 300,000 each

year.

03

Test and Diagnosis Accelerate Fault Location and Troubleshooting

Huawei summarized experience from many trouble tickets and

established corresponding knowledge and experience model. 16 types of

test and diagnosis assets are summarized and integrated into Huawei's

OSS solution. For example, in case of Internet connection failure,

low Internet access rate, and slow IPTV switching, the OSS solution

provides comprehensive diagnosis policies and processing logic, and

supports diagnosis execution, helping service personnel improve

troubleshooting success rate and reducing customer complaints. The

solution enables problems to be solved at the call center without being

transferred to the network operations center (NOC) or left for onsite

troubleshooting, minimizing troubleshooting time and cost and reducing

customer complaints. Huawei has successfully helped carrier P improve

one-time troubleshooting success rate from 50% to 80% and reduce

onsite troubleshooting activities from 30% to 18%. US$-3 million in

savings per year achieved as a result.

04

Field Management: Right Personnel at Right Place and at Right Time

Field maintenance contributes to 70% of carriers' network O&M cost, so

field maintenance efficiency is crucial. Learning from global MS projects,

Huawei has summarized over 10 types of typical field maintenance

service models. Based on big data analytics, Huawei's OSS predicts

project requirements, network capacity, air conditions, the lifecycle of

network elements (NEs), and develops corresponding plans to realize

visualized management of field tasks, personnel, sites, and vehicles. As

a result, appropriate personnel will be sent to the "right place at the right

time". With the latest mobile apps and terminals, Huawei's OSS equips

field personnel with remote access to apps in real time thus, improving

their work efficiency by 20%.

Active Performance Management and Assurance

Huawei has developed over 200 rules for network performance analysis.

These rules are compatible with multi-vendor devices and cover many

fields, including the KPI calculation rule, performance alarm threshold-

crossing rule, and the topic analysis rule. Huawei's OSS solution helps

carriers conduct rule-based semi-automatic network performance

analysis and realize automatic and centralized network performance

management. The OSS supports real-time network performance

monitoring to quickly identify root causes and trouble shoot problems

thereby, actively protecting carriers' network. Successful project

practices showed an efficiency increase of 24.8%.

As Huawei's OSS solution is applied in more and more projects,

Huawei's OSS asset library will further be enriched and optimized,

helping global carriers improve network O&M efficiency.
