Abstract:

A method for policing APN-AMBR includes, at P-GW including plural P-GW DP worker instances: receiving, uplink data to be transmitted over a non-GBR bearer associated with a first PDN session from a first UE via an AP or downlink data to be transmitted over the non-GBR bearer to the first UE via the AP; forwarding the uplink or downlink data to a first P-GW DP worker instance of the plurality of P-GW DP worker instances that is assigned to the PDN session; and, at the first P-GW DP worker instance, transmitting, to an APN-AMBR policer separate from the P-GW, a request for a slice of APN-AMBR capacity for processing the uplink or downlink data. The method further includes, at the APN-AMBR policer: maintaining records of APN-AMBR capacity used by UEs having PDN sessions assigned to different ones of the P-GW DP worker instances; and granting or denying the request based on the APN-AMBR capacity used by the PDN sessions assigned to the different ones of the P-GW DP worker instances.
