METHOD AND SYSTEM FOR DYNAMICALLY TRIGGERING ACCESS AND MOBILITY POLICY CHANGE
Document Type and Number:
WIPO Patent Application WO/2022/062797
Kind Code:
A1
Abstract:
The present disclosure provides a method and system for dynamically triggering an access and mobility (AM) policy change. The method for dynamically triggering AM policy change comprises: when a predetermined application is started or terminated, an AF generates an AM policy grant update request, the AM policy grant update request comprising identification information associated with the application; the AF sends the AM policy grant update request to a PCF entity by means of an NEF entity; the PCF entity obtains a policy parameter associated with the identification information; the PCF entity sends an AM policy identifier and the policy parameter to an access network side device by means of an AMF entity; the access network side device performs corresponding radio resource scheduling according to the policy parameter.
