About this document

Purpose

This document provides the call flows for LTE performance measurements for the eNodeB, MME, and SGW in the Alcatel-Lucent LTE system. Performance measurements provide the basis for performance evaluation, capacity engineering, and help in troubleshooting. Note: Not all LTE PMs are included in the call flows. Audience

This document is intended for use by engineers, technicians, and system administrators who are responsible for wireless network monitoring, performance, trouble shooting, Radio Frequency (RF) optimization, and configuration. Assumed knowledge

The reader must be familiar with: • • •

General knowledge of eNodeB and MME performance measurement counters Understanding of LTE elements and procedures as specified in 3GPP TS 23.401 v8.6.0 Understanding of NAS Messaging as specified in 3GPP TS 24.301

•

Understanding of Tunneling messaging as specified in 3GPP TS 29.274.

Basically, the reader should have an understanding of the performance measurements and an understanding of the LTE procedures that make up the call flows. Related information

1.1 Call Flows with Performance Measurements Overview

This document provides the call flows for LTE performance measurements for the eNodeB, MME, and SGW in the Alcatel-Lucent LTE system. Performance measurements provide the basis for performance evaluation, capacity engineering and help in troubleshooting. To understand the meaning of these performance measurements, it is necessary to understand the relative sequence of pegging these measurements. Call flows provide useful context for showing the sequence of events and when the PMs are pegged under what conditions. The scenarios contained herein are selected sunny and rainy day scenarios. 3GPP2 Handovers are covered in this version. Handovers to 3GPP will be provided in a future version of this document. Note that not all of the LTE PMs are included in the call flows. The scope of this document includes PMs for eNodeB, MME, and SGW. Call flows are based on scenarios defined in 3GPP TS 23.401. Maintenance actions that result in specific PMs being pegged are not covered in this document. For a complete list of eNodeB PMs, please refer to document 418-000-035, Alcatel-Lucent 9412 eNodeB Counters Reference Guide. For a complete list of MME PMs, please refer to document 418-111-209, Alcatel-Lucent 9471 MME Observation Counters. For a complete list of SGW PMs, please refer to document 418-111-xxx (to be determined). Guide to the Document

The diagrams in the document indicate where PMs are pegged in the eNodeB, MME, and SGW. The eNodeB PMs are in the green ovals in the diagrams. The MME PMs are blue. And the SGW PMs are in purple. Triggers for pegging PM counts may be receipt of a

particular message or the sending of a particular message, as shown in the example below for the eNodeB counts. Also, sometimes more than one PM may be pegged at the same point in the call flow, such as in the MME oval. The following is a sample diagram provided only to show how PMs are represented.

Legend:

eNodeB PMs are represented in the green text. MME PMs are represented in the blue text. SGW PMs are represented in the purple text.

PRELIMINARY

FAILURE SCENARIOS: The call flows for failure scenarios depict where in the call flow certain errors can occur and the corresponding failure counters that are pegged as a result of the failure. Most of the failure call flows show multiple error scenarios. Typically, if the error occurs and the call flow ends at that point, an EXIT will be shown in the call flow. This indicates that the rest of the call flow would not continue. If the error does not occur, the success counter would be pegged (refer to success scenarios) and the call flow continues until if/when it encounters another error. In some cases, a failure does not end the call flow, in which case, a Continue will be shown in the call flow.
