A very important step in plug-and-play is network discovery. The following two network discovery methods are mainly used in the prior art:

The first network discovery method: the network devices involved in the network discovery process include: AP, external domain name resolution system (DNS, Domain Name System), initial security gateway (initial SeGW, initialSecurity GateWay), internal domain name resolution system and initial family (evolution Formula) base station management system (initial H(e)MS, initial Home(E)NodeB Management System), where the initial home (evolved) base station management system means that the base station management system can be the initial home base station management system or the initial home Evolved base station management system. In this application scenario, the network discovery process includes: the AP establishes a secure connection with the initial SeGW according to the full domain name (FQDN, Fully Qualified DomainName) or Internet Protocol (IP, Internet Protocol) address of the initial SeGW, and then according to the initial H(e ) MS’s full domain name or IP address to establish a connection with the initial H(e)MS, and the network discovery process is completed when the connection is successfully established.
