Section: 4.3.17 Support for Machine Type Communications (MTC) 4.3.17.1 General
Content: This clause provides an overview about functionality for Machine Type Communications according to service requirements described in TS 22.368[ Service requirements for Machine-Type Communications (MTC); Stage 1 ]  [66]. The specific functionality is described in the affected procedures and features of this and other specifications. For discrepancies between this overview clause and the detailed procedure and function descriptions, the latter take precedence. MTC functionality is provided by the visited and home networks when the networks are configured to support machine type communication. It applies to both the non-roaming case and the roaming case and some functionality may be dependent upon the existence of appropriate roaming agreements between the operators. Some of the MTC functions are controlled by subscriber data. Other MTC functions are based on indicators sent by the UE to the network. MTC functionality is performed by UEs that are configured to support different options as described in clause 4.3.17.4. Though motivated by scenarios and use cases defined in TS 22.368[ Service requirements for Machine-Type Communications (MTC); Stage 1 ]  [66], the functions added to support MTC have general applicability and are in no way constrained to any specific scenario or use case except where explicitly stated. Unless otherwise stated in this specification, MTC functionality also applies over satellite access.
