Abstract

The embodiment of the invention discloses a data management method, a related product and a communication system. A session record is stored in BSF equipment, the session record is created by PCF equipment, and the method comprises the following steps: the BSF equipment sends a positioning parameter of the session record to the PCF equipment; and the BSF equipment receives a response message returned by the PCF equipment, and deletes the session record if determining that the session corresponding to the positioning parameter does not exist on the PCF equipment according to the response message. On the premise of ensuring the storage capacity of the BSF equipment, the session stability can also be ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data management method, related products and a communication system. Background technique [0002] The third generation partnership project (3rd generation partner project, 3GPP) defines a session binding function (binding support function, BSF) device; the BSF device provides a 5G core network (5G core, 5GC) network session binding function, Help network exposure function (network exposure function, NEF) equipment or application function (application function, AF) equipment in the multi-policy control function (policy control function, PCF) equipment network, select the user equipment according to the address of the user equipment. The PCF device applies for a quality of service (quality of service, QoS) policy. [0003] The session record is included on the BSF device. After the 5G-supporting user equipment goes online, the PCF device calls the service application prog...
