Control of access by intermediate network element for connecting data communication networks
First Claim
1. An access control method in an intermediate network element for connecting a plurality of data communication networks including a local network and a global network, comprising the steps of:
- determining whether or not a connection from a local node in the local network to a global node in the global network is disconnected; and
accepting an access from the local node to the global node when the connection from the local node to the global node is determined to be disconnected in the step of determining.

Abstract
An access control method for a plurality of data communications networks is disclosed that enables a plurality of local nodes (101) to communicate with each other even if the connection between an intermediate node (103) and a global server (105) is momentarily lost. In this method, when the connection to the global server (105) breaks down, the intermediate node (103) temporarily grants access to the local nodes (101) instead of the global server (105) in accordance with a predetermined policy, thus allowing operation of local networks to function normally until connection to the global network (104) is resumed.
