The present document specifies the functional architecture, procedures, information flows and APIs for MSGin5G Service. MSGin5G Service provides messaging communication capability in 5GS especially for Massive Internet of Things (MIoT).
MSGin5G Service includes the following message communication models:
- Point-to-Point message;
- Application-to-Point message/ Point-to-Application message;
- Group message;
- Broadcast message.
- MSGin5G Store and Forward;
- Message communication based on Messaging Topic;
- Message Aggregation;
- Message Segmentation and Reassembly;
- Message Gateway to interwork with non MSGin5G messaging services;
- Usage of Network Capabilities including UE reachability status monitoring and MSGin5G device triggering.

3.1 Definitions p. 10
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
AS-to-Point messaging:
an MSGin5G message delivery that is originated at an Application Server in the network and terminated at a UE.
Broadcast Area:
an area consisting of one or more cells where the broadcast message is delivered.
Broadcast Messaging:
an MSGin5G message delivery that is delivered to UEs in a Broadcast Area.
Broadcast Message Gateway:
the entity in MSGin5G Service to support delivery Broadcast messages to Legacy 3GPP UEs, Non-3GPP UEs and MSGin5G UEs.
Constrained UE:
an MSGin5G UE which cannot connect to the 3GPP network directly for message exchange with MSGin5G Server.
Group Messaging:
message delivery that is originated at a UE or an Application Server and is terminated at all members of the group (a group member can be of type UE, Legacy 3GPP UE or Non-3GPP UE).
Legacy 3GPP Message Gateway:
the entity in MSGin5G Service to support interworking with Legacy 3GPP UEs.
Legacy 3GPP UE:
the UE that supports legacy 3GPP message sending and receiving (e.g. SMS, NIDD, etc) in MSGin5G Service.
MSGin5G Client:
the client that enables MSGin5G message sending and receiving.
Message Gateway:
general terminology for Legacy 3GPP Message Gateway, Non-3GPP Message Gateway, or Broadcast Message Gateway.
MSGin5G Gateway UE:
an MSGin5G UE that can provide access to multiple constrained UEs to connect to the 3GPP network for MSGin5G services.
MSGin5G Group:
the group of UEs which members may be MSGin5G UE, Legacy 3GPP UE and Non-3GPP UE.
MSGin5G message:
the message defined in the present specification that is exchanged between the MSGin5G Service endpoints under the MSGin5G Service.
MSGin5G Server:
a server in MSGin5G Service that receives and delivers MSGin5G messages among MSGin5G Service endpoints.
MSGin5G Service:
an MNO message service using the 5G System that enables Point- to-Point, AS-to-Point, Point-to-AS, Group and Broadcast message delivery for thing-to-thing communication and person-to-thing communication.
Messaging Topic:
an identifier for a topic to which a UE or an Application Server can subscribe to in order to receive messages that are characterized by a Message Topic.
MSGin5G UE:
the UE that uses MSGin5G Client in MSGin5G Service.
Non-3GPP Message Gateway:
the entity in MSGin5G Service to support interworking with Non-3GPP UEs.
Non-3GPP UE:
the UE that supports non-3GPP message sending and receiving (e.g. RCS message as specified in GSMA PRD RCC.07 [3], OMA LWM2M message as specified in OMA OMA-ERELD-LightweightM2M [4]) in MSGin5G Service.
Non-MSGin5G UE:
general terminology for Legacy 3GPP UE or Non-3GPP UE.
Point-to-AS messaging:
an MSGin5G message delivery that is originated at a UE and terminated at an Application Server.
Point-to-Point messaging:
an MSGin5G message delivery that originates at a UE and terminates at a UE, where at least one of the end points is a MSGin5G UE.
