8 Procedures and information flows p. 28

The configuration procedure is used to get the MSGin5G Service configuration information (e.g. UE Service ID). The configuration procedure is used by the MSGin5G UE or used by Message Gateway on behalf of the Non-MSGin5G UE. The MSGin5G Service configuration information is used in the future messaging communication.

The VAL UE configuration data specified in TS 23.434 is used in this configuration procedure. After the configuration procedure, the MSGin5G UE, or the Message Gateway on behalf of the Non-MSGin5G UE can register to MSGin5G Server.

8.1.2 MSGin5G UE Configuration p. 29

In the MSGin5G UE configuration procedure, the MSGin5G UE acts as Configuration management client specified in TS 23.434.

The following steps of configuration management service apply for the MSGin5G UE:

Send the Get VAL UE configuration request specified in clause 11.3.2.1 of TS 23.434;
Receive the related Get VAL UE configuration response specified in clause 11.3.2.2 of TS 23.434;

The usage of the above information flows is clarified as below:

The MSGin5G UE ID works as VAL UE ID which is mandatory in the Get VAL UE configuration request;
The UE Service ID works as VAL user ID;
The service identifier of MSGin5G Service works as VAL service ID;

Besides the IEs specified in clause 11.3.2.1 of TS 23.434, the information in Table 8.1.2-1 is also included in the Get VAL UE configuration request.

Besides the functionalities of Configuration Management Server specified in TS 23.434, the MSGin5G Configuration Function should also check whether the MSGin5G UE ID (i.e. VAL UE ID) is included in a former Get VAL UE configuration request.

If so, the MSGin5G Configuration Function included the UE Service ID assigned to the MSGin5G UE in the former configuration procedure as a part of VAL UE configuration data,
Otherwise, a new UE Service ID is assigned to the MSGin5G UE and included in the VAL UE configuration data.

Then the MSGin5G Configuration Function processes the configuration request according to the service policy.

8.1.3 Message Gateway Configuration for support of Non-MSGin5G UE p. 30

The Message Gateway performs the configuration procedure on behalf of the Non-MSGin5G UE to get the MSGin5G Service configuration information (e.g. UE Service ID).

If Configuration Management service in SEAL is used for the Message Gateway configuration, the Message Gateway acts as Configuration management client specified in TS 23.434 on behalf of each Non- MSGin5G UE.

The following steps of configuration management service may apply for the Message Gateway:

Send the Get VAL UE configuration request specified in clause 11.3.2.1 of TS 23.434;
Receive the related Get VAL UE configuration response specified in clause 11.3.2.2 of TS 23.434;

The usage of the above information flows is clarified as below:

An Information Element contains both Non-MSGin5G UE ID and MGW Service ID works as VAL UE ID which is mandatory in the Get VAL UE configuration request;

NOTE 2:
The Non-MSGin5G UE ID may differ among different VALs and may not be unique among different Gateways. It is not enough to use only Non-MSGin5G UE ID as VAL UE ID.
The UE Service ID works as VAL user ID;
The service identifier of MSGin5G Service works as VAL service ID;

Besides the IEs specified in clause 11.3.2.1 of TS 23.434, the information in Table 8.1.3-1 is also included in the Get VAL UE configuration request.

Table 8.1.3-1: Additional Information in the Get VAL UE configuration request

Non-MSGin5G UE information	O	Other information needed by the configuration procedure. (see NOTE)
NOTE: The information can be the device type, device Vendor, etc. It is specified by application provider or MSGin5G Service provider and is out of scope of this document. The MSGin5G Service provider can configure the Non-MSGin5G UE with different configuration data based on this IE. E.g. all sensors can be configured to a same MSGin5G Server.

The information in Table 8.1.3-2 is included in the Get VAL UE configuration response as a part of VAL UE configuration data. The information is used by Message Gateway to support non-MSGin5G UEs that will be used to register with the MSGin5G Server for MSGin5G service.
