9.3.3 Information flows p. 43

9.3.3.1 SEALDD URLLC transmission request p. 43

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. 43

See clause 9.2.3.2 for the details of information flow.

9.3.3.3 SEALDD URLLC transmission connection establishment request p. 43

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.

Table 9.3.3.3-1: SEALDD URLLC transmission connection establishment request

Information element	Status	Description
SEALDD client ID	M	Identity of the SEALDD client.
VAL UE/user identity	O	The VAL user ID of the VAL user or VAL UE ID
SEALDD flow ID	M (See NOTE 1)	Identity of the SEALDD flow.
VAL server ID	O (See NOTE 1)	Identity of the VAL server.
VAL service ID	O (See NOTE 1)	Identity of the VAL service.
SEALDD traffic descriptors	O	A 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 adaptation	O (See NOTE 2)	Indicates BAT and periodicity adaptation capability for SEALDD client in client side initiated request.
Transmission assistance info	O (See NOTE 2)	Indicates transmission assistance information for uplink SEALDD traffic in 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 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: Only one of these IEs may be present in the message.

9.3.3.4 SEALDD URLLC transmission connection establishment response p. 44

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.

Table 9.3.3.4-1: SEALDD URLLC transmission connection establishment response

Information element	Status	Description
Result	M	Indicates the success or failure of establishing the SEALDD connection.
SEALDD traffic descriptors	O	A 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.
Cause	O (See NOTE 1)	Indicates the reason for the failure, e.g. SEALDD policy mismatch.
Capability for BAT and periodicity adaptation	O (See NOTE 2)	Indicates BAT and periodicity adaptation capability for SEALDD client in server side initiated request.
Transmission assistance info	O (See NOTE 2)	Indicates transmission assistance information for uplink SEALDD traffic in 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: Only one of these IEs may be present in the message.

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.

Table 9.3.3.5-1: SEALDD URLLC transmission connection update request

Information element	Status	Description
SEALDD client ID	M	Identity of the SEALDD client.
SEALDD flow ID	M (See NOTE)	Identity of the SEALDD flow.
VAL server ID	O (See NOTE)	Identity of the VAL server.
VAL service ID	O (See NOTE)	Identity of the VAL service.
SEALDD traffic descriptors	O	A 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 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.
