A mobile network operator provides a mix of voice and data services to its sub-

scribers. The subscribers demand high uptime, high bandwidth, and high qualityfor increasingly complex services at lower prices. All of this puts pressure on the

mobile network operator to have a cost effective and efcient network operations

department.

One specic process that helps the operator organization in meeting these de-

mands is network troubleshooting as illustrated in the Figure below.

• Fault Detection: The troubleshooting engineer uses a tool for identifying the

network elements with worst performance according to certain Key Performan-

ce Indicators (KPIs). This task is typically highly automated.

• Diagnosis Creation: Each of the identied network elements with poor perfor-

mance is diagnosed to determine the root cause of problems. The troubleshoo-

ting engineer uses a set of performance monitoring tools to carry out this task.

This task is mainly manual and based on human experience.

• Solution Deployment: When a root cause is determined for a network ele-

ment, a trouble ticket is typically raised for someone to go and conduct a repair

action. As part of Solution Deployment, the troubleshooting engineer validates

the repair action.

The network troubleshooting process

Concept Descr ip t ion

The 2solve Troubleshooting Suite is a product for operators who wants to auto-mate troubleshooting processes in their network operation center. The product can

be delivered as a turnkey solution including a ready-made reasoning model which

ensures rapid implementation and thereby immediately adds value to the organi-

zation.

2operate has developed a new concept to support the troubleshooting process

from Fault Detection, over Diagnosis Creation, to Solution Deployment.

Where traditional troubleshooting toolsets provide automation only in the Fault

Detection task, 2operate is able to automate Diagnosis Creation as well as part

of the validation task in Solution Deployment. The solution has been designed to

capture data in each troubleshooting incident when the root cause is known, such

that it will continuously become more accurate in its automated Diagnosis Creation

function.

Arch i t ectu re Overv iew

The 2solve Troubleshooting Suite is the core of the 2solve product portfolio. It is aweb application running on a server in the operators IT environment, as illustrated

in the Figure below.

The 2solve Troubleshooting Suite is installed in a web server with data stored in

the 2solve Database. The user will access the tool from a web browser (as a web

client). This means that there is little installation overhead when deploying and

upgrading the solution in the operator organization.

• Dashboard: View and build a user-specic dashboard using a list of readymade portlets. The portlets can be congured by the user in order to provide

the exact content that the user needs in each situation.

• Localized Application: 2solve comes in English, French, and Danish, and

can be provided in any language with little overhead. Each individual user can

choose his/her own language among those supported in the installed version.

•

Network Topology: Browse the network topology in a hierarchical tree andfrom there utilize the core functionality of the system.

• Worst Performance Analysis: Find network elements with poor performance

according to certain KPIs.

• Performance Alarms: Spot whenever a network element starts showing ab-

normal performance according to certain KPI thresholds.

• GIS: View the network elements in a GIS (Geographical Information System).

The elements are shown on the map at their geographical location and from

here you can click on elements to immediately get a diagnosis as a top 3 list of

most probable faults.• Diagnostic Performance Monitoring: A panel showing a predened set of

KPIs along with a diagnosis for individual network elements.

• Troubleshooting Case Handling: Create troubleshooting cases for individual

network elements when a problem seems present. In addition to traditional

trouble ticket information, the troubleshooting case contains KPI snapshots

(a snapshot is KPI readings for a certain time window) and the identied root

cause(s) when the problem is solved.

• Build Reasoning Model: Build a model from scratch by specifying the root

causes (faults) and KPIs that should be used by the application. The relation-

ship between root causes and KPIs are also specied along with the strength of the relationship.

• Maintain Reasoning Model: Existing models can be updated or extended to

match new requirements and perform even better.

• Reasoning Model Learning: Select cases and learn a specic reasoning

model from these cases.

• Reasoning Model Performance: Select a reasoning model and view its

success rate.

• KPI Specifcations: Specify thresholds for KPIs (for the Performance Alarms

function).

A d m i n i s t r a t i v e f u n c t i o n al i t y

• User Management: Manage users and specify roles of each individual user.

There are three roles: ”Troubleshooter”, ”Model Maintainer”, and ”Administra-

tor” which can be used in any combination.

• Network Responsibilities: Assign sub networks to individual ”Trouble-

shooter” to enable focus and efciency in the troubleshooting process.

Com pany Backgr ound

2operate is a high tech start-up company established in 2009 by a team of ex-

perienced software/telecom engineers to develop and market a new, innovative

solution to support troubleshooting processes in network operations organisations.

2operate was placed at NOVI, a business park at the campus of Aalborg University

in Denmark. Based on experience from two large scale European research projects

2operate has developed a new concept with products and processes that enables

mobile network operators to reach a high level of process automation leading to

cost reductions without sacricing quality.
