DATA RATE AWARE SCHEDULING IN ADVANCED WIRELESS NETWORKS
First Claim
1. A method, comprising:
- receiving, by a computing device, a policy to limit subscriber traffic over a particular bearer for an Internet protocol (IP) wireless access network, where the policy includes a particular quality-of-service control indicator (QCI) value, and one or more of an uplink data rate limit or a downlink data rate limit;
detecting, by the computing device, network congestion associated with the IP wireless access network; and
calculating, by the computing device, a bandwidth allocation for the bearer based on the QCI value and the one or more of the uplink data rate limit or the downlink data rate limit.

Abstract
A base station for an Internet protocol (IP) wireless access network receives an initial attach request from a user device. Based on the initial attach request, a policy and charging rules function (PCRF) device provides to the base station, a subscriber bearer policy that includes a particular quality-of-service control indicator (QCI) value, an uplink data rate limit, and a downlink data rate limit. The base station calculates an uplink bandwidth allocation, based on the QCI value and the uplink data rate limit, that is proportionate to the total maximum data rate of all uplink traffic with the same QCI value. The base station also calculates a downlink bandwidth allocation, based on the QCI value and the downlink data rate limit, that is proportionate to the total maximum data rate of all downlink traffic with the same QCI value.

10. A device, comprising:
-
a memory to store a plurality of instructions; and a processor to execute instructions in the memory to; receive a policy to limit subscriber traffic over a particular bearer for an Internet protocol (IP) wireless access network, where the policy includes a particular quality-of-service control indicator (QCI) value and an access point name aggregated maximum bit rate (APN-AMBR) value; detect network congestion associated with the IP wireless access network; and calculate a bandwidth allocation for the bearer based on the QCI value the APN-AMBR value. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method, comprising:
-
receiving, by a base station for an Internet protocol (IP) wireless access network, an initial attach request from a user device; providing, by a policy and charging rules function (PCRF) device and based on the initial attach request, a subscriber bearer policy that includes a particular quality-of-service control indicator (QCI) value, an uplink data rate limit, and a downlink data rate limit; receiving, by the base station, the subscriber bearer policy; providing, by the base station and to the user device, an uplink bandwidth allocation based on the QCI value and the uplink data rate limit; and applying, by the base station, rate limiting of downlink traffic to the user device based on the QCI value and the downlink data rate limit. - View Dependent Claims (18, 19, 20)
