Physical Architecture Inter-operability

focus change from element management to information management

Open architecture : reuse widely used standards & technologies

Interfaces

Ift-N : between the NE/EM and the NM OSF, standardized

Ift-T : between a terminal and the OSF, for further study (Rel. 5)

Management Application Protocol : CMIP, CORBA, SNMP

Application Protocol for bulk transfer : FTAM, FTP, TFTP

Network protocol : IP, X.25

Integration Levels

Screen Integration

Unified screen : not to be standardized now

Application Integration

High-level generic interfaces

• Between generic & product-specific applications

• Define Network Infrastructure IRPs : top-down, open

Detailed (product-specific) interfaces

• Between product-specific applications and NEs

• Traditional TMN approach to EM : need not be open

11

Information Architecture

Performance Management Concept & Requirements

Measurement data

• traffic measurements Network configuration

evaluation

• Resource access Quality of Service

• Resource Availability

Measurement Schedule : start and stop time

The granularity period : 5 minutes, 15 minutes, 30 minutes, 1 hour

Measurement reporting : scheduled measurement reports

Measurement job state and status attributes

Measurement job administration

• Create, Modify, Display, Delete, Suspend, Resume

35

Performance Data

Measurement Report File : Naming

<Type><Startdate>.<Starttime>-

<Enddate>.]<Endtime>_<UniqueId>[:<RC>]

Measurement Report File : Format

measFileHeader, measData, measFileFooter

ASN.1 Specification

XML Specification: using DTD

Measurement Definition Template

Description Collection Method Condition Measurement Result

Measurement Type Measurement Object Instance Switching Technology

Only measurement types specific to 3G networks are defined

Measurements for RNC, NodeB, MSC, HLR, VLR, EIR …

May re-use GSM measurements

36

Charging and Billing

Circuit Switched Domain (Circuit Service) : TS 32.005 (Rel. 99)

Define management services (tariff administration, data collection)

• Tariff administration

– Tariff class management

– Tariff period management

– Day class management

– Tariff management

– Tariff system management

• Data collection : Data generation control, Data transfer control

Bulk transfer : FTAM

37

Charging and Billing Packet Switched Domain (Packet Service) : TS 32.015 (Rel. 99)

Transfer charging information from the SGSN and GGSN nodes

to the network operator’s chosen Billing Systems(BS)

through Charging Gateway Functionality(CGF)

Charging Data Collection Types

• S-CDR : GPRS charging data in SGSN

• G-CDR : GPRS charging data in GGSN

• M-CDR : GPRS MS mobility management data in SGSN

• S-SMO-CDR : GPRS MO SMS data in SGSN

• S-SMT-CDR : GPRS MT SMS data in SGSN

Charging Protocol : GTP (Optional)

Information format of CDRs : ASN.1
