The invention discloses a strategy control method, device and system. The method comprises the following steps: after a strategy control network element receives an updating request message sent by afirst mobility management network element, a strategy control network element sends the updating request message; according to the updating request message, the information of the second mobility management network element in the information associated with the strategy corresponding to the terminal and stored in the strategy control network element can be updated into the information of the firstmobility management network element, and the information of the first mobility management network element is carried in the updating request message. The strategy control network element needs to delete the information of the second mobility management network element in the information associated with the strategy corresponding to the terminal; and the information of the second mobility management network element in the information associated with the policy corresponding to the terminal is directly updated to the information of the first mobility management network element without re-establishing the policy association with the first mobility management network element, so that the resource overhead of policy control can be saved.
Description
technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a policy control method, device and system. Background technique [0002] In the fifth generation (5th generation, 5G) system, access and mobility management function (access and mobility management function, AMF) network elements can interact with policy control function (policy control function, PCF) network elements in order to obtain terminal policies and access and mobility management policies. Moreover, during the process of terminal registration to the network, the AMF network element will establish a policy association with the PCF network element, and the PCF network element provides the policy to the AMF through the policy association. [0003] In the scenario of AMF reselection, the AMF network element before reselection is called Old AMF, and the AMF network element after reselection is called NewAMF. During the AMF reselection process, wh...
