Customer Experience Management (OSS – focused) – MTS Russia implementation
Sergey BougaevProject Supervisor at Mobile TeleSystems
21st November 2013
Agenda
Goals and challenges: • improve customer experience by transforming traditional resource-
centric network management into service and customer service-centric management
• establish pro-active service incident management• introduce business oriented, customer service centric view of network
quality Milestones:
• OSS structured transformation – transition from the network layer through the service layer up to the Customer Layer
Current picture of achieved transformation • How different departments take advantage of SQM/CEM solution –
examples of SQM/CEM usage Further plans

MTS Group
One of the leading telecommunication groups in Russia, Eastern Europe and Central Asia
More than 100 mln mobile subscribers 8 Macro-regions in Russia
Project names: NGSA (Next Generation Service Assurance) and extPM (extended Performance Management)
Main tools in GNOC (Global Network Operation Centre)
4
MTS Challenges and expected solutions
• Limited visibility of technology resources in service chain
SQM/CEM enables visibility of customer (mainly probing) and service layers– assuming no access to PM data from access layer, focusing on
monitoring of the services based on core network elements– monitoring of gateways/ interfaces/ connections, thus controlling
application layer as well
• Keeping operational control over the services delivered to customermonitoring of services instead of resources (both NGSA and combined SQM/CEM)– controlling if users are using the service, if it works, and how they use it
5
MTS Challenges and expected solutions
• Limited capabilities in terms of financials and HR– high level of automation (monitoring of selected customers, VIPs)– proactive approach (tackling the issue before it becomes visible to the
user, e.g., prediction algorithms, statistical computation)
• Management Layer/OSS flexibility and platform openness– open architecture, documented APIs– scalable and extendable
• Service/Products Lifecycle shortening– instant configuration of services and monitoring options by the system
users – no need for assistance from Comarch side– thanks to friendly and intuitive GUI huge reduction of time needed for
service configuration and enabling of service monitoring

OSS structured transformationMain causes…
Technical driven causes
• Operators wasted their time for routine tasks
• Lack of automation
• Lot of time wasted for the management of alarms that are not important
• Operators had to use additional systems to get information about
resources, hardware, connection, alarms, actual state of the resource,
other vendor specific data, etc.
• Decentralized monitoring structure
• Each MR had specific structure and division of responsibilities
• OSS systems landscape differed between MR (lack of standarization,
difficult to maintain)
• No common approach to network monitoring9
OSS structured transformation …and goals of the project
Main goals of the project
• Unification of OSS landscape
• Transformation from existing legacy, silos based OSS systems to the
NGOSS environment
• The implementation of unified umbrella solution in assurance area
above different NEM/EMS systems distributed over the whole Russia
• The introduction of Service layer and the definition of dependencies on
the network layer
• Standardize and minimize the amount of alarms
• Ensure the correct performance of the network and delivery of sold
services
10
OSS structured transformation Scope of NGSA project
Convergent solution based on the following modules:
• Comarch Next Generation Service Assurance (NGSA)
• Fault Management
• Service Monitoring
• OSS Process Management
• Comarch Service Inventory (SI)
• Comarch SLA Monitoring (SLAM)
Comarch’s responsibilities:
• the analysis and implementation of above modules
• consulting services in order to centralize network operation
• participation in the process of defining the concept of centralized NOC
as well as in the realization process 11
OSS structured transformationNGSA project results
The centralized network monitoring platform:• One umbrella system for all Alarms
• Alarm enrichment with NE, Location and Customer Details
• Alarm reduction by suppression & correlation• The additional prioritization of alarms according to the importance of
specific devices• Impact analysis by use of service affecting alarms via service and
customer models
The standardized operator’s work environment
• One system – one GUI (Operators View)
Automation of routine and time consuming tasks• Semi and automatic triggering of TT creation, update and close
• One click actions perform on NEs (scripts embedded and run directly from the NGSA GUI)
12
OSS structured transformation Scope of GNOC project and results
OSS organizational structure transformation:
• Centralization of network monitoring
• Establishment of new processes
• Establishment of new positions
• Reorganization of working groups
13
OSS structured transformation Use cases implementation
Movement profile of subscribers
Modification of Alarm Priority based on the weighted average of
Number of observed subscribers in Cell area
Monitoring of static GPRS devices
Calculation of SLA related KPIs for Enterprise customers

OSS structured transformation SQM/CEM introduction
• Building unified NGOSS Platform by:
– Continuation towards the calculation of impact on customer and
resource-facing services by giving insight into customer perception
covered by implementation of:
• Comarch SQM
• Comarch CEM
• Comarch PM
18
Use Case flow
19
DATA collection
• XDRs used as an input by CEM system • Current: ISUP, CAP, MAP, BICC, INAP, IuPS, Gn control and
user plane, Gp, Gb, – Future: Diameter, S1AP, S1U, SCTP, Diameter, SIP etc
• KPIs based on various dimensions: IMSI, MSISDN, CellID, IMEI
• KPIs calculated for different types of customers : „human”, M2M, roamers.
20
Maintenance and monitoring cases
• Voice service monitoring:– NER, ASR, CSSR, Call Duration Statistics, Call Failure Histogram (base on REL cause
code) and etc.
• SMS service monitoring:– SMS MO success rate, SMS MO/MT Count and Statistics, SMS MO Error Distribution
of Causes and etc.
• Registration statistics:– Location Update/Location Update GPRS – Count, Success Rate, Error Rate, Error
Distribution of Causes– SAI - Count, Success Rate, Error Rate, Error Distribution of Causes– and etc.
• DATA service:– Activate PDP – Count, Success Rate, Error Rate, Error Distribution of
Causes– Data service user plane calculation for HTTP, IMAP4, POP3, DNS and etc.– and etc.

Operations
SQM can provide to Operations: Service KQI which prioritize faults and reduce
effort required for Incident Management Network problems presumptions Depiction of fault (e.g. TCE) impacting services Propagation of network events towards services Root cause analysis Prediction algorithms of service outages
Value for business:• Operational cost savings
• Cost to monitor (€/incident)• Cost to fix (€/incident)• Cost to deploy (€/service/subscriber)• Cost to provision (€/service/subscriber)
• Improve reduce number of service outages (€/service/subscriber)
23
Customer Care
SQM can provide to call agent:• a view of current service degradations • a view of current/recent problems of a
subscriber • a view of current problems on geographical
