Claim:
A method for network terminals to access a service network system, comprising: receiving, by a digital gateway equipment, an access request to the service network system initiated by a second network terminal, wherein the second network terminal is not configured with subscriber certification information; and providing, by the digital gateway equipment, an access proxy to the service network system for the second network terminal by the use of the subscriber certification information configured on a first network terminal, wherein after the second network terminal initiating the access request completes the access certification by the use of the access proxy, the method further comprises: receiving, by the digital gateway equipment, a service request to the service network system initiated by the accessed network terminal; determining, by the digital gateway equipment, whether a service capability of the accessed subscriber initiating the service request meets service capability requirements of the service request; wherein if yes, the digital gateway equipment sends the service request to the service network system; otherwise, the digital gateway equipment requests the second network terminal initiating the service request to reregister, and performs registration for a subscriber meeting the service capability requirements according to the service capability requirements in a re-registration request sent by the second network terminal and the subscriber certification information configured on the first network terminal.
