Problems solved by technology

[0004] In the case of a high uplink peak rate, if the UE frequently sends DNS queries to the EASDF in a malicious manner in a short period of time, the EASDF frequently sends reports to the SMF and triggers multiple signalings on the control plane, which will cause signal failure in the mobile communication system. The storm causes a denial of service (Denial Of Service, DOS) attack, causing the mobile communication system to fail to serve all normal UEs

Abstract

The invention discloses a report control method and device, equipment and a medium, and belongs to the field of mobile communication. The method comprises the following steps that: a SMF sends control information to EASDF, wherein the control information is used for forbidding or stopping or reducing the report sent by the EASDF to the SMF. According to the method and the device, the EASDF cannot send a report to the SMF without limitation, so that DOS attacks initiated by abnormal UE are defended, and a mobile communication system is guaranteed to provide services for more UE as much as possible.

Description

technical field [0001] The embodiments of the present application relate to the field of mobile communications, and in particular to a report control method, device, equipment and medium. Background technique [0002] In an edge computing scenario, a domain name system (DomainName System, DNS) query sent by a user equipment (User Equipment, UE) may be processed by an edge application server discovery function (Edge Application Server Discovery Function, EASDF). [0003] The session management function (Session Management Function, SMF) provides reporting (Reporting) rules and forwarding (Forwarding) rules to EASDF. The report rules provide the rules for EASDF to send reports to SMF, and the forwarding rules provide the rules for EASDF to forward messages. After the UE sends a DNS query to the EASDF, the EASDF will send a report to the SMF according to the reporting rules. [0004] In the case of a high uplink peak rate, if the UE frequently sends DNS queries to the EASDF i...
