Telepoint system which charges an account of the subscriber rather charging an account of the private base station through a call is established

Claim 1

A telepoint system comprising the following elements, which are interconnected via a telephone network: a digital exchange (DIV0) with a server (S) for checking subscriber identities, public telepoint base stations (TP), and private base stations (1, 2, 3), each having a cordless handset (HS1, HS2, HS3, HS3') and a subscriber permanently associated therewith, and wherein a call can be established from any first cordless handset (HS1) by a first subscriber to a second subscriber in the telephone network via every public telepoint base station (TP) and via every private base station (2, 3) not permanently associated with said first handset (HS1), the first subscriber known as a nonassociated subscriber with respect to said every private base station not permanently associated with said first handset, wherein said call establishment is by the first subscriber transmitting a subscriber identity from said first cordless handset (HS1) and checking in the server (S) whether the identity of the first subscriber is that of a subscriber authorized to access the telepoint system, and if said first subscriber is authorized to access the telepoint system, sharing any public telepoint base station (TP) and any private base station (2, 3) with said authorized first subscriber; and further wherein the server (S) bills the charge for a call established from said first cordless handset (HS1) by the first subscriber via the private base station (2) with which said first cordless handset (HS1) is not permanently associated, by charging an account of the first subscriber rather than charging an account of the subscriber associated with the private base station (2) through which said call is established.
