KEY
LTE CPI DOCUMENTS
›Some
key CPI documents to get started with Ericsson LTE RAN:
–System and
Node Description
›Overview of LTE RAN system
& RBS node, including high-level description of system architecture,
interfaces, hardware & key functions
›
–Network Impact
Report
›Describes how new or changed
features for a specific release can impact existing customer network upon
introduction, including capacity, performance, hardware, interfaces, network
elements & observability
›
–Key
Performance Indicators
›Describes LTE RAN KPIs used to
measure subscriber perceived quality and system performance
›
–Parameter and
Counter Limitations
›Lists unsupported
parameters/ranges, counters, events and alarms
›
–Flowcharts for
Counters
›Flowcharts for main traffic
scenarios & relevant counters, indicating how & when these counters are
pegged
›
–Managed Object
Model (MOM)
›A view of all the manageable
resources in the node, and all the associated parameters, counters and actions
›
–Feature
Descriptions
›Describes feature operation,
including main benefits & impacts in LTE RAN
System
& Node Description
›Some important chapters:
–Hardware: Includes high-level description of digital
unit & radio unit functions
–
–Traffic interfaces: Includes protocol stacks for control plane
& user plane, high-level description of air interface protocols
–
–Bearers & Services,
etc: Include high-level
definitions/terminology for different LTE bearers
–
–Scheduler: Overview of scheduler inputs/resources &
associated features
–
–QoS: High-level overview of QoS & associated features
FLOWCHARTS
for COUNTERS
›Description document
contains flowcharts for the main traffic sequences that impact performance
statistics counters in the RBS
–Only a subset of available
counters is included in the document
–
›Flowcharts are drawn
from RBS perspective & are meant to give some insight into the
implementation of the counter
–E.g. when it is stepped,
related counters, etc.
