A system described herein may allow for an Aggregate Maximum Bit Rate (“AMBR”) to be applied across multiple sessions. Using such techniques can allow multiple different traffic types (e.g., as denoted by a Data Network Name (“DNN”)) to share an AMBR. Additionally, an AMBR can be calculated, tracked, and enforced across multiple sessions associated with multiple devices. Some techniques may cause a particular Session Management Function (“SMF”) to be selected when establishing a session, such that the SMF can calculate, track, and enforce the AMBR across multiple sessions that are in the same AMBR group.
