database and adding aliases to MAC (
Media Access Control) addresses in the mapping files; and the residential gateway comprises a background 
service module, a residential gateway native 
database and a residential gateway native 
software module, wherein the residential gateway management module accesses to the residential gateway native database, and the background 
service module is managed through the residential gateway native 
software module in a matching manner. According to the 
system and the method, parameters for setting the residential gateway can be queried, corresponding WiFi SSID (
Wireless Fidelity 
Service Set Identifier) and / or 
password information of the residential gateway and the smart terminal are updated synchronously, and latest smart terminal App or residential gateway 
software is actively pushed to users, so that the upgrading operation is simplified.
