Abstract

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products directed to analytics-based user plane optimization are provided. A first network entity (NE) may receive, from a second NE, information indicating analytics based operation for access traffic steering, splitting and switching (ATSSS), and first weights and a first weighting factors for multiple access networks; transmit, to a third NE, information indicating the analytics based operation, including the first weights and weighting factors; transmit, to a fourth NE, information indicating load metrics; receive, from the fourth NE, information indicating analytics for controlling traffic steering for a multi-access protocol data unit session, including second weights and/or second weighting factors for the multiple access networks, wherein the analytics are based on the load metrics and criteria for partitioning downlink traffic among the multiple access networks; and transmit, to the third NE, information indicating the second weights and/or second weighting factors.

Claims20

Dependent claims

A method implemented in a first network entity, the method comprising:

receiving, from a second network entity, first information indicating (i) analytics-aided load-balance operation for access traffic steering, splitting and switching, (ii) a first weight for each of a plurality of access networks, and (iii) at least one first weighting factor for each of the plurality of access networks;
transmitting, to a third network entity, second information indicating (i) the analytics-aided load-balance for access traffic steering, splitting and switching, (ii) the first weights, and (iii) the first weighting factors;
transmitting, to a fourth network entity, third information indicating one or more load metrics, wherein the one or more load metrics are based on the first weights and the first weighting factors;
receiving, from the fourth network entity, fourth information indicating analytics for controlling traffic steering for a multi-access protocol data unit session, including one or more of (i) a second weight for at least one access network of the plurality of access networks and (ii) a second weighting factor for at least one access network of the plurality of access networks, wherein the analytics are based on:
(a) the third information transmitted to the fourth network entity, and
(b) fifth information, from the third network entity, indicating criteria for partitioning downlink traffic among the plurality of access networks;
and
transmitting, to at least one of the third network entity and a wireless transmit/receive unit, WTRU, sixth information indicating the one or more of (i) the second weight and (ii) the second weighting factor.

A first network entity comprising:

a processor, memory, and a transceiver which are configured to:
receive, from a second network entity, first information indicating (i) analytics-aided load-balance operation for access traffic steering, splitting and switching, (ii) a first weight for each of a plurality of access networks, and (iii) at least one first weighting factor for each of the plurality of access network,
transmit, to a third network entity, second information indicating (i) the analytics-aided load-balance operation for access traffic steering, splitting and switching, (ii) the first weights, and (iii) the first weighting factors,
transmit, to a fourth network entity, third information indicating one or more load metrics, wherein the one or more load metrics are based on the first weights and the first weighting factors,
receive, from the fourth network entity, fourth information indicating analytics for controlling traffic steering for a multi-access protocol data unit session, including one or more of (i) a second weight for at least one access network of the plurality of access networks and (ii) a second weighting factor for at least one access network of the plurality of access networks, wherein the analytics are based on:
(a) the third information transmitted to the fourth network entity, and
(b) fifth information, from the third network entity, indicating criteria for partitioning downlink traffic among the plurality of access networks;
and
transmit, to at least one of the third network entity and a wireless transmit/receive unit, WTRU, sixth information indicating the one or more of (i) the second weight and (ii) the second weighting factor.
