3.1 Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 [1], TS 23.501 [2] , TS 23.502 [3] and TS 23.503 [4] apply. A term defined in TS 23.501 [2], TS 23.502 [3] or TS 23.503 [4] takes precedence over the definition of the same term, if any, in any other specifications.

RG Level Wireline Access Characteristics: Wireline access technology specific QoS information corresponding to a specific wireline access subscription, which is provided by the AMF to the W-AGF at RG registration.

Wireline access Control Plane protocol (W-CP): Protocol used to transport AS and NAS signalling between the 5G-RG and the W-AGF over the Y4 reference point. W-CP is specified by BBF and CableLabs. There is no assumption that W-CP refers to only a single protocol or only a specific protocol layer.

Wireline access User Plane protocol (W-UP): Protocol used to carry PDU Session user plane traffic between the 5G-RG and the W-AGF over the Y4 reference point. W-UP is specified by BBF and CableLabs. There is no assumption that W-UP refers to only a single protocol or only a specific protocol layer.

Legacy Wireline access Control Plane protocol (L-W-CP): L-W-CP is a legacy control plane protocol between the FN-RG and W-AGF. L-W-CP is specified by BBF and CableLabs. There is no assumption that L-W-CP refers to only a single protocol or only a specific protocol layer.

Legacy Wireline access User Plane protocol (L-W-UP): L-W-UP is a legacy user plane protocol between the FN-RG and W-AGF. W-UP is specified by BBF and CableLabs. There is no assumption that L-W-UP refers to only a single protocol or only a specific protocol layer.

For the purposes of the present document, the abbreviations given in TR 21.905 [1], TS 23.501 [2], TS 23.502 [3] and TS 23.503 [4] apply. An abbreviation defined in TS 23.501 [2], TS 23.502 [3] or TS 23.503 [4] takes precedence over the same abbreviation, if any, in any other specifications.
