Core network and access point for filtering information, and information filtering method thereof

An access point comprised in an access network, a plurality of the access networks being connected to a core network, the access point being configured for connecting user equipments to the core network, the access point comprising:

• a local storage storing a plurality of modules, a first relationship between connecting configurations of the access point and the access network the access point belongs to, and a second relationship between different types of the access networks and information needed to be filtered;
• and
• a processor to execute the plurality of modules, wherein the plurality of modules comprises:
• an obtaining module to obtain connecting configuration of one access point when the core network determines to send information to user equipment connected to the core network via the access point;
• a determining module to determine which access network the access point belongs to according to the first relationship, determine which type the determined access network is, and determine the information needed to be filtered according to the second relationship;
• and
• a filtering module to filter the determined information to prevent the determined information from being accessed by the user equipment.

An information filtering method applied in a core network, the core network connected to a plurality of access networks, each access network comprising at least one access point for connecting user equipments to the core network, the core network comprising a cloud storage for storing a first relationship between connecting configurations of each access point and the access network each access point belongs to, and a second relationship between different types of the access networks and information needed to be filtered, the method comprising:

• obtaining connecting configuration of one of the at least one access point when the core network determines to send information to user equipment connected to the core network via the access point;
• determining the access point belongs to which access network according to the first relationship;
• determining which type the determined access network is;
• determining the information needed to be filtered according to the second relationship;
• and
• filtering the determined information to prevent the determined information from being accessed by the user equipment.
