9.3.3  Information flows  p. 54

9.3.3.1  SEALDD URLLC transmission request  p. 54

See clause 9.2.3.1 for the details of information flow with the following clarification:
  • The bandwidth related IEs are not applicable.

9.3.3.2  SEALDD URLLC transmission response  p. 54

See clause 9.2.3.2 for the details of information flow.

9.3.3.3  SEALDD URLLC transmission connection establishment request  p. 54

Table 9.3.3.3-1 describes the information flow from the SEALDD client to the SEALDD server or from the SEALDD server to the SEALDD client for requesting the URLLC transmission connection establishment.
Information element Status Description
SEALDD client IDOIdentity of the SEALDD client.
IdentityOThe VAL user ID of the VAL user or VAL UE ID
SEALDD-UU flow IDsM
(See NOTE 1)		Identity of the SEALDD-UU flows.
VAL server IDO
(See NOTE 1)		Identity of the VAL server.
VAL service IDO
(See NOTE 1)		Identity of the VAL service.
SEALDD traffic descriptorsOA pair of SEALDD traffic descriptors (e.g. address, port, transport layer protocol) of the SEALDD client side (for client side initiated request) or the SEALDD server side (for server side initiated request) used to establish redundant SEALDD connection.
Capability for BAT and periodicity adaptationO
(See NOTE 2)		Indicates BAT and periodicity adaptation capability of the SEALDD client (for client side initiated request).
For URLLC transmission, it includes capability for BAT and periodicity adaptation per SEALDD traffic descriptor.
Transmission assistance infoO
(See NOTE 2, NOTE 3)		Indicates transmission assistance information for uplink SEALDD traffic of the SEALDD client side (for client side initiated request).
It includes BAT, BAT window, periodicity, and periodicity range.
For URLLC transmission, it includes assistance information per SEALDD traffic descriptor.
NOTE 1:
The SEALDD-UU flow ID is used by the SEALDD client and SEALDD server to identify different application traffic, and it is mapped from the VAL service ID.
NOTE 2:
If provided, BAT window and periodicity range are mutually exclusive with capability for BAT and periodicity adaptation.
NOTE 3:
The periodicity range may only be present together with the periodicity when BAT and BAT window are present. The BAT window may only be present together with the BAT.

9.3.3.4  SEALDD URLLC transmission connection establishment response  p. 54

Table 9.3.3.4-1 describes the information flow from the SEALDD server to the SEALDD client or from the SEALDD client to the SEALDD server for responding to the URLLC transmission connection establishment.
Information element Status Description
ResultMIndicates the success or failure of establishing the SEALDD connection.
SEALDD traffic descriptorsOA pair of SEALDD traffic descriptors (e.g. address, port, transport layer protocol) of the SEALDD server side (for client side initiated request) or the SEALDD client side (for server side initiated request) used to establish redundant SEALDD connection.
CauseO
(See NOTE 1)		Indicates the reason for the failure, e.g. SEALDD policy mismatch.
Capability for BAT and periodicity adaptationO
(See NOTE 2)		Indicates BAT and periodicity adaptation capability for SEALDD client in server side initiated request.
For URLLC transmission, it includes capability for BAT and periodicity adaptation per SEALDD traffic descriptor.
Transmission assistance infoO
(See NOTE 2, NOTE 3)		Indicates transmission assistance information for uplink SEALDD traffic of the SEALDD client side (for server side initiated request).
It includes BAT, BAT window, periodicity, and periodicity range.
For URLLC transmission, it includes assistance information per SEALDD traffic descriptor.
NOTE 1:
The IE is only present if the Result is failure.
NOTE 2:
If provided, BAT window and periodicity range are mutually exclusive with capability for BAT and periodicity adaptation.
NOTE 3:
The periodicity range may only be present together with the periodicity when BAT and BAT window are present. The BAT window may only be present together with the BAT.

9.3.3.5  SEALDD URLLC transmission connection update request  p. 55

Table 9.3.3.5-1 describes the information flow from the SEALDD client to the SEALDD server for requesting the URLLC transmission connection update.
Information element Status Description
SEALDD client IDMIdentity of the SEALDD client.
SEALDD-UU flow IDsM
(See NOTE)		Identity of the SEALDD-UU flows.
VAL server IDO
(See NOTE)		Identity of the VAL server.
VAL service IDO
(See NOTE)		Identity of the VAL service.
SEALDD traffic descriptorsOA pair of SEALDD traffic descriptors (e.g. address, port, transport layer protocol) of the SEALDD client side used to establish redundant SEALDD connection.
NOTE:
The SEALDD-UU flow IDs is used by the SEALDD client and SEALDD server to identify different application traffic, and it is mapped from the VAL service ID.

9.3.3.6  SEALDD URLLC transmission connection update response  p. 55

Table 9.3.3.6-1 describes the information flow from the SEALDD server to the SEALDD client for responding to the redundant transmission connection update.
Information element Status Description
ResultMIndicates the success or failure of updating the SEALDD connection.
CauseO
See NOTE		Indicates the reason for the failure, e.g. SEALDD policy mismatch.
NOTE:
The IE is only present if the Result is failure.
