Method for filtering packets coming from a communication network

摘要

The method involves associating a registration context to a terminal (20), where the context comprises registration information transmitted between the terminal and a mobility management service platform during registration. A filtering rule is created from the registration context for blocking the packets that do not satisfy a part of the registration information. The packets are filtered based on the created rule. Independent claims are also included for the following: (1) an entity for filtering packets from a communication network (2) a program comprising program code instructions for implementing a packet filtering method (3) a readable storage medium for storing the program.
