› CM tools provide the operator with
– An efficient way of configuring, verifying and viewing large amount
of parameters that are defined in the network
– Gathering and storing configuration information from the NW
– Tracking changes that are made to the configuration

User Authorization
› Restricting the usage of the OSS system for user groups
› example
– Authorization to run an O&M application
– Allowing to perform an operation
– Authority model
› Target: NE or application
› Activity
› Type: connecting activities to targets

Self Organizing
Networks (SON)
› Standard requirements defined by 3GPP on simplifying O&M of LTE
NWs
› Minimizing OPEX
› High level of automation
› SON architectures
– Centralized
› SON algorithms reside on the OSS servers
– Distributed
› SON algorithms reside on the NW elements
– Hybrid
Ericsson Internal | 2012-04-25 | Page 20
Self Organizing
Networks (SON)
› Self planning
– Self configuration
– Self optimization
› Automated Neighbour Relation:
› Based on detected cell reports from the UE automatic discovery
of undefined LTE cell neighbours
› Self healing

eTOM (enhanced Telecom
Operations Map)
› Telekom Management Forum & ITU standardized
interfaces to allow consistent management of NEs from
different suppliers
› a reference framework and common language for defining

Why analitics
› NW elements generate huge amount of data
› In other industries same trends happen M2M
communication
› Internet of things (IOT)
– Tera/peta Byte
– structured
– unstructured
› Analytics can give insights about trends connected this
data
– Reporting - what happened
– Analyzing - why happened
– Predicting - what will happen

Customer Experience
Management
› Customer care
› Network operation Center
› Marketing
› Measurement of the perceived individual customer
experience across the terminal, radio access and mobile
core
– In real-time
– For all customers 24/7
– With high accuracy
› ›Automatically provides the most probable cause and
