Subscriber group quality of service adjustments

A method, comprising:

• providing a respective aggregate maximum bit rate (AMBR) to each subscriber of a plurality of subscribers of a cellular telecommunication network such that a total of the respective AMBRs provided to the plurality of subscribers is equal to a total maximum bandwidth capacity of the cellular telecommunication network available to the plurality of subscribers at a network node, wherein the respective AMBR includes at least one of:
• user equipment-AMBR (UE-AMBR), protocol data unit-AMBR (PDU-AMBR) and network slice based AMBR (SMBR);
• receiving a quality of service (QoS) request from a particular subscriber of the plurality of subscribers for an increased AMBR;
• detecting, via a network data analytics function (NWDAF) of the cellular telecommunication network, an increased level of current network congestion affecting a respective portion of bandwidth capacity currently available to each subscriber of the plurality of subscribers on the on the cellular telecommunication network;
• and
• based on the detected increased level of current network congestion, increasing the respective AMBR provided to the particular subscriber by a first amount in response to the request while also decreasing respective AMBRs provided to one or more other subscribers of the plurality of subscribers by a collective total of a second amount.

A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed by at least one computer processor, cause actions to be performed including:

• providing a respective aggregate maximum bit rate (AMBR) to each subscriber of a plurality of subscribers of a cellular telecommunication network such that a total of the respective AMBRs provided to the plurality of subscribers is equal to a total maximum bandwidth capacity of the cellular telecommunication network available to the plurality of subscribers at a network node, wherein the respective AMBR includes at least one of:
• user equipment-AMBR (UE-AMBR), protocol data unit-AMBR (PDU-AMBR) and network slice based AMBR (SMBR);
• receiving a quality of service (QoS) request from a particular subscriber of the plurality of subscribers for an increased AMBR;
• detecting, via a network data analytics function (NWDAF) of the cellular telecommunication network, an increased level of current network congestion affecting a respective portion of bandwidth capacity currently available to each subscriber of the plurality of subscribers on the on the cellular telecommunication network;
• and
• based on the detected increased level of current network congestion, increasing the respective AMBR provided to the particular subscriber by a first amount in response to the request while also decreasing respective AMBRs provided to one or more other subscribers of the plurality of subscribers by a collective total of a second amount.
