DEVICE FOR CONNECTING A TELEPHONE SWITCH TO A FIXED TELEPHONE NETWORK VIA A RADIOTELEPHONE NETWORK

摘要

The invention concerns a device for connecting a telephone switch to a fixed telephone network (PSTN) via a radiotelephone network (PLMN) of the GSM type or derived therefrom, comprising at least a fixed radiotelephone terminal (RT) including means for identifying all calls containing an identity pertaining to a predetermined international mobile subscriber identity (IMSI) set, and for identifying all calls containing an identity pertaining to a temporary mobile subscriber identity (TMSI) set, each of the sets corresponding to subscriber terminals (UT1, ..., UT10) connected to said switch. The device enables the radiotelephone network to establish a separate invoice for each subscriber terminal (UT1,..., UT10), though a common fixed radiotelephone terminal (RT) is used by different subscribers; and the radiotelephone network can operate a direct selection of incoming calls, towards each subscriber terminal (UT1,..., UT10).
