Abstract: A mobile telephone network stores a list of short dialling codes in association with each user's identity so as to define the short codes which each individual user is permitted to use for providing access to a data conversion device which gives access to a private network. When a short code is dialled on a mobile station, calling data comprising the short code together with caller identification data derived from the mobile station are transmitted over the radio link to the mobile switching center. Prior to routing the call, the identity of the dialling station is authenticated. The short code in the calling data is then compared with the permitted list of short codes to determine whether the user is permitted to make the call. If the caller is permitted to make the call, the call is routed to a destination corresponding to the data conversion device. Thus, only permitted users may access the data conversion device.

Abstract: A system/method is disclosed for screening telephone system callers, using speaker-dependent text-independent voice recognition, to either prevent excessive fraudulent use of certain telephone system lines (or radio channels) or to selectively restrict classes of service allowed for different users of a common line. The voice recognition process is configured to provide an extent of mismatch indication, between a voice sample taken from a caller immediately using the protected line (or channel) and a recorded reference voice sample, which indication corresponds to the probability that the instant caller is not the same as the person who provided the reference sample. The extent of mismatch indication is compared to a mismatch limit value which can be set to a different magnitude for each call. Different actions are taken depending upon whether the extent of mismatch indication is or is not larger than the limit value.
