How to distinguish compliance multi-end and private sharing in the operator's dialing scene

In the proxy and multi-operator environments, account-end-position linkages distinguish normal from unusual sharing.

Under the proxy setting, multiple devices appearing under an account number may be compliant (e.g. cellular plus computers in the same room) or irregular (e.g. shared on the whole floor). The key to distinguishing is “position concentration.” It is more normal if multiple terminals are concentrated at the same access switchboard port or in the same room; if different floors and even buildings are shared with the same account number, there is a significant increase in suspicion of sharing it.
