Configure and enforce maximum data rate per UE per network slice

An apparatus comprising:

• one or more processors;
• and
• memory storing instructions of node of a Next Generation Radio Access Network (NG-RAN) for a wireless communication network, the instructions, when executed by the one or more processors, cause the apparatus to perform operations, the operations comprising:
• receiving a maximum data rate for a subscriber for a network slice;
• associate all packet flows of the subscriber for the network slice to a logical channel group;
• determining whether a hypothetical total data rate of the logical channel group exceeds the maximum data rate for the subscriber for the network slice in an event a grant to transmit data through the logical channel group is provided to the subscriber;
• and
• inhibiting providing the grant for the transmission of the data through the logical channel group to the subscriber if the hypothetical total data rate of the logical group exceeds the maximum data rate for the subscriber for the network slice.

A method for wireless communication, the method comprising:

• retrieving, by an Access and Mobility Management Function (AMF) from a Unified Data Management, subscription information for a subscriber, wherein the subscription information comprises a respective maximum data rate for the subscriber for each of one or more network slices allowed for the subscriber;
• maintaining, by the AMF, an aggregate Guaranteed Bitrate (GBR) for the subscriber for each of the one or more network slices, wherein the aggregate GBR is a sum of the GBRs of active Protocol Data Unit (PDU) sessions of the subscriber for respective network slices;
• and
• in response to a request for an additional PDU session or a request for modification of an active PDU session, of the active sessions, for the subscriber on a network slice of the one or more network slices, performing, by the AMF, an admission control for the additional PDU session or a modification control for the active PDU session for the subscriber on the network slice of the one or more network slices, wherein the admission control or the modification control is based on the respective maximum bit rate and the aggregate GBR for the network slice.

A non-transitory computer-readable medium comprising a set of instructions of an Access and Mobility Management Function (AMF) encoded thereon which, when executed by an apparatus, cause the apparatus to perform:

• retrieving, from a Unified Data Management, subscription information for a subscriber, wherein the subscription information comprises a respective maximum data rate for the subscriber for each of one or more network slices allowed for the subscriber;
• maintaining an aggregate Guaranteed Bitrate (GBR) for the subscriber for each of the one or more network slices, wherein the aggregate GBR is a sum of the GBRs of active Protocol Data Unit (PDU) sessions of the subscriber for respective network slices;
• and
• in response to a request for an additional PDU session or a request for modification of an active PDU session, of the active sessions, for the subscriber on a network slice of the one or more network slices, performing an admission control for the additional PDU session or a modification control for the active PDU session for the subscriber on the network slice of the one or more network slices, wherein the admission control or the modification control is based on the respective maximum bit rate and the aggregate GBR for the network slice.

A method for wireless communication, the method comprising:

• receiving, by a Next Generation Radio Access Network (NG-RAN), a maximum data rate for a subscriber for a network slice;
• associate, by the NG-RAN, all packet flows of the subscriber for the network slice to a logical channel group;
• determining, by the NG-RAN, whether a hypothetical total data rate of the logical channel group exceeds the maximum data rate for the subscriber for the network slice in an event a grant to transmit data through the logical channel group is provided to the subscriber;
• and
• inhibiting, by the NG-RAN, providing the grant for the transmission of the data through the logical channel group to the subscriber if the hypothetical total data rate of the logical channel group exceeds the maximum data rate for the subscriber for the network slice.
