2. The complexity of modern communication services and the number of support groups that need visibility of their quality
and performance is beyond the scope of traditional network management systems. Therefore, telecom service provider
revenue has become dependent on the rapid introduction of complex services in an increasingly competitive market.
Telco support groups struggle to monitor and manage these new services as the rate of service introduction increases.
NOCs today have limited ability to:
?Monitor end-to-end throughput from eNode-B to the application server in the NDC across each network element and
interface
?Correlate multiple alarms to identify the cause of a throughput SLO violation and identify the network
element/interface responsible
?Identify the number of customers impacted for each sub service type
?Identify the types of customers(domestic, enterprise and international in-roamers) facing the performance degradation
based on IMSI grouping
Unified Services Platform:
For customer retention, services must be managed holistically, in real time, from the moment the service is made available
to the customer. To ensure customer experience and ultimately customer retention, service providers need solutions that
can be implemented rapidly and provide full visibility to all service impacting scenarios.
The following are the benefits of a Unified Services Platform:
?End-to-end visibility into the throughput being delivered across the network and ability to identify potential bottlenecks
?Ability to prioritize restoration efforts based on number of customers impacted
?Ability to generate a service impact view of a resource outage/performance degradation
Snapshot of the business model:
Introduction
The services platform should be able to monitor end-to-end service performances delivered across the network, identify
the KPI/KQI/SLO violations and the network element/interface responsible as part of the RCA.
?Monitoring both at LTE Control plane signaling and Bearer plane is paramount
?Service KQI is dependent on both application and network layer matrices
?Measure & Monitor Network equipment usage, link Latency & jitter, throughput
?Use probes, periodic performance data, active alerts and thresholds
