Abstract: This application provides a cache decision method and apparatus. The method includes: receiving, by a policy control function PCF, first cache information sent by at least one local analytic function LAF. The first cache information includes a base station identifier, identifiers of first N1 pieces of application information that are accessed for a maximum quantity of times, and content corresponding to the identifiers of the N1 pieces of application information, where N1 is a positive integer. The method further includes determining, by the PCF, local cache content based on the first cache information and a capacity of a local cache. In this way, the cache hit rate can be effectively improved, transmission bandwidth and data transmission overheads can be greatly reduced, and users' experience improved.

Abstract: In an access and mobility management policy association termination method, a first access and mobility management function apparatus sends first policy control function identifier information of a first policy control function apparatus to a second access and mobility management function apparatus, and sends first deletion request information to the first policy control function apparatus. The first deletion request information is for requesting the first policy control function apparatus to delete an access and mobility management (AM) policy association between the first policy control function apparatus and the first access and mobility management function apparatus for a terminal device. Both the first access and mobility management function apparatus and the first policy control function apparatus then delete AM policy control information for the terminal device.
