5  MTC communication aspectsWord‑p. 8

5.1  MTC communication scenarios

5.1.1  Introduction

For MTC communication the following communication scenarios can be identified:
  1. MTC Devices communicating with one or more MTC Server;
  2. MTC Devices communicating with each other.

5.1.2  MTC devices communicating with one or more MTC servers

The network operator provides network connectivity to MTC Server(s). This applies to MTC Server(s) controlled by the network operator (refer to figure 5-1) or to MTC Server(s) not controlled by the network operator (refer to figure 5-2.)
Reproduction of 3GPP TS 22.368, Figure 5-1: Communication scenario with MTC devices communicating with MTC server. MTC server is located in the operator domain.

Reproduction of 3GPP TS 22.368, Figure 5-2: Communication scenario with MTC devices communicating with MTC server. MTC server is located outside the operator domain.
Up
The MTC Device and the MTC Server it is communicating with may implement a service enablement framework (e.g. as specified in [4] and [5]) to provide generic functionality for applications. The MTC Device may implement multiple instances of service enablement frameworks, each communicating with a different MTC Server.

5.1.3  MTC devices communicating with each otherWord‑p. 9

The communication scenario where the MTC Devices communicate directly without intermediate MTC Server (refer to figure 5-3) is not considered in this release of the specification.

6  Categories of features for Machine-Type Communications |R11|Word‑p. 10

Machine-Type Communication (MTC) applications do not all have the same characteristics. This implies that not every system optimization is suitable for every MTC application. Therefore, MTC Features are defined to provide structure for the different system optimization possibilities that can be invoked. MTC Features provided to a particular subscriber are identified in the subscription. MTC Features can be individually activated.
The following MTC Features have been defined:
  • Low Mobility;
  • Time Controlled;
  • Small Data Transmissions;
  • Infrequent Mobile Terminated;
  • MTC Monitoring;
  • Secure Connection;
  • Group Based MTC Features:
    • Group Based Policing;
    • Group Based Addressing.
