A device for connecting a telephone switch to a fixed telephone network via a plurality of fixed radiotelephone terminals of a radiotelephone network, a plurality of user terminals being connected to said telephone switch, said device including a plurality of fixed radiotelephone terminals each including means for communicating with said radiotelephone network, said means including a processor, each of the fixed radiotelephone terminals being in one only of the following states: listening out for terminal seek messages, or in telephone communication with the radiotelephone network, or available, a terminal being considered to be available even if it is executing a location or authentication procedure, wherein the device further includes coordinator means connected to each of the processors of the fixed radiotelephone terminals to control dynamically allocation of said terminals to telephone connections set up between the fixed telephone network and the user terminals, wherein each fixed radiotelephone terminal includes means for indicating its status to the coordinator means, and wherein the coordinator means include means for activating at any time one only of the fixed radiotelephone terminals chosen from those available at the time concerned to listen out for terminal seek messages.
Claim 3
Dependent Claim
98 words
A device according to claim 1, wherein the fixed radio terminals include means for transmitting an identity received in a seek message broadcast by the radiotelephone network to the coordinator means, and wherein the coordinator means contain and update a table of mobile subscriber international identities and mobile subscriber temporary identities corresponding to the user terminals connected to the switch to: determine if a received identity corresponds to one of said user terminals and to respond to the radiotelephone terminal that received it, and if necessary, command said terminal to set up a connection with the radiotelephone network.
Claim 4
Dependent Claim
73 words
A device according to claim 1, wherein a single radiotelephone terminal includes means for authenticating a radiotelephone terminal using the same key for all calls received or transmitted via said fixed radiotelephone terminal, whichever that may be, and wherein the other fixed radiotelephone terminals include means for requesting the coordinating means to indicate to them which fixed radiotelephone terminal includes authentication means and thereafter requesting the designated terminal to perform the authentication procedure.
Claim 5
Dependent Claim
66 words
A device according to claim 1, wherein each fixed radiotelephone terminal further includes means for performing a location procedure for all the international or temporary mobile subscriber identities contained in the table, and wherein the coordinator means include means for choosing one of the available radiotelephone terminals and activating it to perform the location procedure for all the international mobile subscriber identities contained in the table.
