PERIODIC UPDATE BASED 5G SESSION VALIDATION

原文（中国語）

Various embodiments of the present technology generally relate to systems and methods for validating 5G sessions by providing periodic updates from a policy control function (PCF) to a binding support function (BSF). In certain embodiments, a PCF system may comprise one or more processors, and a memory having stored thereon instructions. The instructions, upon execution, may cause the one or more processors to send a binding record request to a Binding Support Function (BSF) for a 5G communication session associated with the PCF, receive a binding record confirmation with a selected revalidation time value that indicates when the 5G communication session will be considered invalid and a binding record associated with the 5G communication session will be deleted, and prior to an expiration of the selected revalidation time value, send a binding record update request to the BSF to refresh the selected revalidation time value.
