An Introduction to CPI and LTE CPI
this presentation is intended for ericsson-internal audiences only
Ericsson Cpi
What is CPI and how is it created, delivered and accessed?

Customer Product Information
› Customer Product Information (CPI) is the technical information needed to handle Ericsson products throughout the product life cycle.
› CPI is intended for Ericsson customers. › CPI does not include marketing or sales information.› CPI does not include information for Ericsson-internal
target groups.› Internal users of CPI are, e.g., services and training.
However, CPI is not adapted to their needs unless it benefits the external customer as well.
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 4 (57)
CPI Delivery Format and Tools
› CPI is published on CPI Store (Ericsson internal) and mirrored to CPI Extranet (external, for customers and partners).http://cpistore.ericsson.se
› CPI is published in a file container called an ALEX library. With the Active Library Explorer (ALEX) tool, the user can browse Ericsson ALEX libraries with a standard browser.
› All Ericsson CPI is required to follow the Generic CPI Structure, which specifies how the information is to be arranged and labelled in the ALEX library.
› Other Ericsson generic requrements on CPI cover areas such as high level information structure, writing style, formats, registration, and supply.

CPI Delivery Format and Tools
› The primary CPI display format is HTML, but PDF is normally also provided.
› CPI is developed in XML format using Tagtool with Ericsson CPI DTDs and style sheets. (Tagtool is a set of tools based on the Arbortext Editor (Epic) from PTC.)

Feedback on cpi?
› Email us.› Call us.› To be sure that action is taken:
Write a TR!› Please be very specific! Give examples. It significantly
increases the chances of a useful update.
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 14 (57)
Organization
› The main responsibility for LTE CPI is located to the LTE System Project Office.
› Anikó Schmidt and Fredrik Smidfelt are LTE CPI System Managers, responsible for e.g. strategic planning, processes and coordination.
› The CPI is developed in CPI projects that follow the system projects.› CPI is a system project delivereable, managed by system PjM. › There is a CPI project manager taking care of the CPI specific detail project
planning and management.› CPI is written by technical writers and system engineers, depending on
information type. Some CPI is auto-generated e.g. from the MOM (lists).
› Language review of all CPI is done by the CPI editor and all illustrations are created by an illustrator team. (Both these tasks are done off site by subcontractors.)
› A large part of the LTE CPI library is produced by other orginizations: CPP, PDU RBS, Site Products.
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 15 (57)
Interfacing Organizations
› The Product Information Discipline within R&D is the central CPIorganization responsible for generic requirements, methods, and tools.
› LTE CPI has interfaces to the CPI organizations for RBS6000, CPP, OSS, WCDMA RAN and Site Products.
› More than half of the documents included in an LTE ALEX are produced by other organizations, manily CPP and RBS.
› There are currently active CPI fora for cooperation, coordination and alignment on varying levels between LTE and: RBS HW, RBS SW, and CPP-based nodes.
› LTE also takes part in a forum for DU Radio CPI and in PI Discipline meetings and activities.
› Other important interfaces are OSS, RAN I&V and BUGS (=services).
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 16 (57)
The 70% Reduction objective
› When starting LTE CPI development, we had a requirement to reduce CPI by 70% as compared to WCDMA.
› What? size, volume, complexity, COST
› How?- Avoid “nice to know” information- Avoid describing textbook and standards information (3GPP), provide reference/link instead- Page count limit for some document types- Increase auto-generated CPI (lists)- Single source: system documentation = CPI- Simplified system and product = less to describe- All LTE CPI in one ALEX.
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 17 (57)
What else is new?
LTE CPI structure is based on and very similar to WCDMA CPI.
Some differences:› All LTE CPI contained in one single ALEX library› Slightly different concept and template for feature descriptions = “user
descriptions”› Managed Area Description (MAD) concept fully adopted from start› “Library Overview” replaced by “Finding Information in the Library” with
FAQ style information› “Parameter and Counter Limitations” (new document)› No man pages, except those instructing how to access man pages› Minor differences in alarm instructions due to different input data

Feature Description Concept for LTE RAN
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 23 (57)
background
› Concept idea by Greg Harman GSDC Australia temporarily working with EAB/FJL/SP in 2008. Previously on the operator side (Telstra).
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 24 (57)
Guiding Principles
› The concept for feature CPI for LTE RAN is based on
– The way Ericsson sells the system to the operators
– The way that the operators use CPI
– The goal to reduce LTE CPI by 70%.
LTE_presentation_Dallas_Feb_2011 | Ericsson Internal | 1/0341-3/FEA 101 8211 Uen, Rev A | 2011-03-08 | Page 25 (57)
TARGET User Profile
› The following profile is assumed for a CPI user who works for an operator
– Has 5 to 15 year experience in the wireless industry (or works for or with someone who fits this profile)
– Has attended Ericsson training (System Overview, Air Interface, Advanced System Techniques etc)
– Has a number of text books on the shelf describing the technology– Has accessed the 3GPP standards website to read selected parts of
the standard– May have worked at Ericsson in the past or may work for Ericsson
in the future

LTE RAN Feature CPI guidelines
› The following guidelines are used for developing LTE RAN feature CPI– Each licensed feature is described in one CPI document: a User
Description . The general rule is that the title is the same as the feature name.
– The content reflects Ericsson’s implementation of the system. Generic, “text book” details of how the system works are not included.
– If the operator can’t change the parameter they don’t need to read about it in CPI.
– A released User Description should only have to be updated if there is a change to the feature.
– The User Descriptions contains: * An impact statement detailing the impact on generic system functions, e.g., capacity, handover, coverage, etc.* Details on feature specific counters* Information on recommended use, based on the intended use of the feature at the time of CPI development

Managed Area Description
› This document type provides information about Managed Areas (MAs). An MA represents a group of functions and Managed Objects (MO) within the node, where each MA is relatively independent of other MAs.
› The MA Description (MAD) explains concepts and gives readers an understanding of how an area is modeled, what functionality is related to the area and how this is managed.
› The MADs provide tool-independent* instructions on how to perform different tasks, for example Add/Remove Cell, Restarting a Fan etc.
› PDU LTE, PDU RBS and CPP write MADs
*Tool-independent means that the instructions only describes what MOs and attributes to set but not whattool to use or how.

Configuration OPIs
› The Configuration OPIs provide instructions about how to perform tasks related to configuration of the products, for example Create Configuration Version, Lock Board, Restart Node etc.

› This document type provides instructions about how to act on specific alarms in order to correct the fault and cease the alarm.
› One alarm (SpecificProblem) equals one Alarm OPI› The SpecificProblem slogan is also the title of the corresponding Alarm OPI › The procedure is presented as a sequence of tasks with one task per step. › There are three origins of Alarm OPIs:
– PDU LTE only– CPP– Common SW
(common for GSM, WCDMA and LTE)
› Target Groups: Field Technician, Network Operator, Network Optimizer, System Administrator
