POLICY APPLICATION METHOD FOR MACHINE TYPE COMMUNICATION AND POLICY AND CHARGING ENFORCEMENT FUNCTION

摘要

A policy application method for Machine Type Communication (MTC) and a Policy and Charging Enforcement Function (PCEF) are provided by the present invention. The method comprises that in a course in which an MTC device attached to a PCEF establishes an Internet Protocol-Connectivity Access Network (IP-CAN) session, the PCEF locally obtains a group policy corresponding to a device group to which the MTC device belongs (S302); the group policy is applied in the IP-CAN session (S304). The technical solution of the present invention reduces the time required by applying the MTC policy by the PCEF, saves network resources, and increases utilization of the network resources.
