Patent ID: 11425598

Abstract:
A method for rules-based overload control for 5G services includes configuring, at an intermediate or a producer network function (NF), overload message handing rules, wherein at least some of the rules include destination network name (DNN), network subscription, network location, or a network slice identifying parameter or any parameter/attribute defined by 3GPP/vendor as rule selection criteria. The method includes a guaranteed processing bandwidth of the intermediate or producer NF with at least some of the overload message handling rules, receiving a first message at the intermediate or producer NF, determining that an overload condition exists, identifying that the first message includes parameters that match the rule selection criteria for one of the overload message handling rules, determining, that a portion of the guaranteed processing bandwidth of the intermediate or producer NF for the matching overload message handling rule is available to process the first message, processing the first message, and updating a message count for the overload message handling rule.
