Abstract
A method, a system, a network element, and a gateway for processing access point name restriction information are disclosed. The method includes: a second mobility management element receives first access point name restriction information from a first mobility management element; the second mobility management element obtains maximum access point name restriction information according to the first access point name restriction information, so that a packet data network gateway determines to or refuses to establish a new packet data network gateway connection. With the present invention, the second mobility management element may obtain the maximum access point name restriction information according to the received access point name restriction information. In this way, the packet data network gateway can determine to or refuse to establish a new packet data network gateway connection, therefore improving the security of private packet data network gateways.
