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, where the bandwidth allocation is proportionate to a total maximum data rate of all uplink traffic with the same QCI value or of all downlink traffic with the same QCI value.

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 particular bearer based on the QCI value and the APN-AMBR value, where the calculating includes applying a weight factor to account for other bearers with the same QCI value and different APN-AMBR values. - View Dependent Claims (11, 12, 13, 14, 15)

16. 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 monitoring resource utilization information of the IP wireless access network; identifying downlink data rate limits of all active bearers under the same QCI value within the IP wireless access network; and calculating a downlink bandwidth allocation for rate limiting of downlink traffic to the user device in proportion to the cumulative data rate limits of the active bearers under the same QCI value; applying, by the base station, rate limiting of downlink traffic to the user device based on the downlink bandwidth allocation. - View Dependent Claims (17, 18)

19. 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, wherein the uplink data rate limit includes an uplink access point name aggregated maximum bit rate (APN-AMBR), and wherein the downlink data rate limit includes a downlink APN-AMBR; detecting, by the computing device, network congestion associated with the IP wireless access network; identifying, by the computing device, active bearers with the same QCI value; 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, wherein the calculated bandwidth allocation for the bearer is in proportion to the APN-AMBR values of the bearer compared to the total of the APN-AMBR values of the active bearers with the same QCI value. - View Dependent Claims (20)
