•MTC : Machine Type Communication•MTCu : Provides MTC devices access to the 3GPP network for the transport of user traffic•MTCi : Reference point for MTC server to connect the 3GPP network via 3GPP bearer service•MTCsms : Reference point for MTC server to connect the 3GPP network via 3GPP SMS
•Explains 3 different type of Communicating scenarios•Scenario 1 (Located in the operator domain)•Scenario 2 (Located outside the operator domain)•Scenario 3 (Communication directly with each other without an intermediate MTC server)
•Comments•Low Mobility, secure connection, group based triggering•Time controlled transmission (only at pre-defined time)•Time tolerant transmission•Network operator shall provide PS service with or without an MSISDN.

Standard body
Domain distribution Interconnection among gateway
Direct device addressability
Interfaces
GISFI 3 domains : Sensor, IoT core, Application/service.Applications do not have direct accessibility to devices
Chaining or interoperation with gateways and application controller. Present , But does not have any interfaces
Device /sensors are addressable . Present.
Three interfaces – I1, I2, I3 – device to device interface is out of scopeI2 ->B5: application server -> smart deviceI2B1. application -intermediate node.I2->B5,B1->mid
ETSI Two domains : Network Domain (includes access , core, & M2M service
capability), Device and Gateway Domain
NA Present (Direct Connectivity from application to device as well as device to device).The M2M Device performs the procedures such as registration, authentication,authorization, management and provisioning with the Network Domain
Three interfaces – mia,mid,dia device to device interfaces are also considered
TIA Two domains : Device & application. Application directly access device gateway & devices
Chaining of intermediate nodes.B6,B7 are defined reference points
Present -Direct Device Interaction. Uses standardized set of verbs applied to a specific device like Set, Get. Device to device interaction is also possible
Intermediate nodes/gateways to gateways interfaces are considered

3GPP 3 different types of communications
NA Alternative addressing solution based on IP addresses . Nodes are addressable
MTC devices communicating with the MTC server through API.(within the access network). MTC server connects to IoT stack through I1 (functionality need to be understood)
MTC device supporting directly Internet, can connect to I2

• I1 Signifies a family of interfaces including the 3rd party network accessibility.
• Device to device connectivity and interfaces are not considered.
• I2 Signifies the interfaces for application middleware/ application to devices directly, as well as application middleware to access gateway. Devices are considered addressable.
• Internet is considered as Backbone network.
• Chaining among application middleware nodes as well as access gateways are considered.
• No interfaces are defined for this. No use case is mapped yet. Chaining of application middleware may suitable for distributed computing.
• I3 (APIs) Interface exposed from application middleware to Application does not exist in ETSI & TIA
