Systems and methods for load control of a user device during network congestion

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may receive traffic data associated with a coverage area and determine that there is network congestion. If there is network congestion, the device may identify a high-consumption user device. The device may perform a corrective action in connection with a load of the high-consumption user device, such as limit a throughput of the high-consumption user device. The device may perform a corrective action based on a policy obtained from a policy and control function.

What is claimed is: 
     
         1 . A method, comprising:
 identifying, by a first device, a congestion event based on processing unit usage at one or more network components;   identifying, by the first device and based on identifying the congestion event, a second device with a load that satisfies a load threshold; and   limiting, by the first device and based on a policy obtained from a policy and control function, the load of the second device based on a stepped-limiting mechanism associated with the processing unit usage.   
     
     
         2 . The method of  claim 1 , wherein the load threshold is implemented based on identifying the congestion event.

 causing a network component to obtain the policy.   
     
     
         4 . The method of  claim 1 , wherein identifying the congestion event is based on determining whether traffic data satisfies a congestion threshold. 
     
     
         5 . The method of  claim 1 , wherein limiting the load of the second device comprises:
 causing a network component to drop packets for the second device.

         10 . The first device of  claim 8 , wherein the one or more processors are further configured to:
 provide, to a network component, information associated with the congestion event; and   instruct the network component to obtain the policy.   
     
     
         11 . The first device of  claim 8 , wherein the one or more processors, are further configured to:
 identify a plurality of user devices impacted by the congestion event.   
     
     
         12 . The first device of  claim 8 , wherein the one or more processors, to perform the corrective action, are configured to:
 cause a serving gateway to notify a core network device that the second device is overloading a network component.   
     
     
         13 . The first device of  claim 8 , wherein the one or more processors, to perform the corrective action, are configured to:
 notify a core network device to limit throughput for the second device.   
     
     
         14 . The first device of  claim 8 , wherein the one or more processors, to perform the corrective action, are configured to:
 apply a quality of service parameter for the second device.   
     
     
         15 . A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
 one or more instructions that, when executed by one or more processors of a first device, cause the first device to:
 identify a congestion event based on processing unit usage at one or more network components; 
 identify, based on identifying the congestion event, a second device with a load that satisfies a load threshold; and 
 perform a corrective action, based on a policy obtained from a policy and control function, associated with the second device based on a stepped-limiting mechanism associated with the processing unit usage. 
   
     
     
         16 . The non-transitory computer-readable medium of  claim 15 , wherein the one or more instructions, that cause the first device to perform the corrective action, cause the first device to:
 enforce an aggregate maximum bit rate for the second device.   
     
     
         17 . The non-transitory computer-readable medium of  claim 15 , wherein the one or more instructions, that cause the first device to perform the corrective action, cause the first device to:
