Method and apparatus for data collection under dynamic network conditions

A network node configured to serve as a data collection function (DCF) for managing a data collection (DC) session, the networking node comprising:

• a processor;
• and
• a transceiver, wherein the processor and transceiver are configured to:
• monitor one or more data collection session using an abnormality detection mechanism configured to detect whether data collection is proceeding in accordance with a data collection policy;
• detect a data collection abnormality based on:
• a notification that collected data fails to meet a data consuming application requirement, a notification that indicates a failure to meet a Quality of Service (QoS) or a Quality of Experience (QoE) requirement, or a notification from a network function (NF) including a forecast or detection of network congestion;
• determine a corrective action based on a corresponding DC management rule and the detected data collection abnormality;
• transmit, to one or more wireless transmit receive units (WTRU)s, a data collection configuration request message based on the determined corrective action;
• receive from the one or more WTRUs, a data collection configuration response message indicating an outcome of the corrective action, the outcome comprising at least one of:
• termination, pause, modification, rejection or update of the DC session;
• and
• transmit to an application function (AF), a message indicating the outcome of the corrective action based on the data collection configuration response message received from the one or more WTRUs.

A method performed by a wireless transmit receive unit (WTRU) participating in a data collection (DC) session, the method comprising:

• initiating a DC session based on at least one of:
• a received data collection policy or a session initiation message from a data collection function (DCF);
• detecting that one or more conditions exist, including at least one of:
• network congestion with Quality of Service (QoS) degradation, activation of a power-saving mode, or incompatible or missing WTRU configuration information;
• transmitting, to the DCF, an anomaly notification comprising a cause code associated with the detected one or more conditions;
• receiving, from the DCF, a data collection configuration update request indicating a corrective action, the corrective action comprising at least one of:
• termination, pause, modification, or update of the DC session;
• updating one or more data collection session parameters based on the corrective action;
• and
• transmitting, to the DCF, a data collection configuration update response, the response indicating the corrective action taken and identifying an associated DC session ID.
