A SYSTEM FOR COMMUNICATING WITH A SINGLE MOBILE COMMUNICATIONS DEVICE HAVING MULTIPLE MS-ISDN IDENTIFIERS

摘要

A communication system (10) comprising a first communications device (12) operable by way of a first telecommunications network (16a); a second communications device (14) operable by way of the first telecommunications network (16a) and at least one additional telecommunications network (16b), each telecommunication network (16) issuing a unique MS-ISDN to the second communications device (14) to enable such operation; and a communications facilitator (20) associated with the first telecommunications network (16a) where, when a communication from the first communications device (12) to the second communications device (14) is received by the communications facilitator (20), the communications facilitator assesses at least one characteristic of the second communications device (14) and/or MS-ISDNs allocated to the second communications device (14) to identify a communication link and relays the communication to the second communications device (14) by way of the additional telecommunications network (16) that allocated the MS-ISDN identified as the communication link.
