• Data model, to view the meter functionality at its interface(s)

• COSEM objects

• OBIS Object Identification System

• Messaging method to communicate with the model and to represent data as a series of bytes (APDUs)

• Transportation method to carry the messages over the media between the meter and remote parties

Separation of model and protocol: “orthogonality”

E2E security

• Access security, messsage security, data security • Several protection layers can be applied by market participant, client, server • Authentication (Integrity), encryption (Confidentiality), digital signature

(Non-repudiation) • Protection can be applied selectively where needed

Efficiency


Message length fits media:

segmentation

Selective access: get only what

you need

Eliminate overhead:

Compact data

Many data with one request:

with-list

Compression Push and pull

operation

Objectives: meet media specific restrictions, minimize overhead and number of round trips >> minimize costs

Communication media and profiles


COSEM Application layer

Connection Messaging

COSEM object model

Lower layers

Media 1: PSTN, GSM

Lower layers

Media 2: TCP/IP

Lower layers

Media n

Application layer: common in any communication profile

• connection between the metering and data collection application processes

• prepares the messages for transport

• encoding

• cryptographic protection

•block transfer

Lower layers ensure that he messages are correctly delivered

e.g. HDLC, TCP/IP, S-FSK PLC, PRIME PLC. G3-PLC, BPLC, M-Bus...

Profile 1 Profile 2 Profile n

Object model: common in all communication profiles. Supports the use cases
