Access information processing method, device and system

The present invention relates to the field of communications, and in particular, to an access information processing method, device, and system. BACKGROUND OF THE INVENTION An Evolved Packet Core Network (EPC) in a network supports not only 3GPP access technologies, such as: UMTS Terrestrial Radio Access Network (UTRAN), access technology, and evolved universal land-based wireless Access technology of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) or access technology of the (GSM EDGE Radio Access Network, GERAN); at the same time, the EPC also supports non-3GPP access technologies, for example: Access technology of the Code Division Multiple Access (CDMA) 2000 network, access technology of the Worldwide Interoperability for Microwave Access (WiMax) network, and access to the Wireless Local Area Networks (WLAN) technology. For a user equipment that supports multiple access technologies, the network side can send user granularity policy information to the user equipment through the Access Network Discovery and Selection Function (ANDSF) server, thereby guiding the user equipment to select an appropriate device.
