Subscriber mobility in telephony systems
First Claim
1. In a telecommunications system comprising a plurality of circuit-switched communication devices corresponding to a plurality of subscribers, a plurality of packet-switched communication devices corresponding to the plurality of subscribers, and at least one of a switch and server, the at least one of a switch and server being in communication with a packet-switched network comprising a plurality of proxy servers and a circuit-switched network and at least one of proxy server has a set of predefined rules directing a contact for a first subscriber to the first subscriber'"'"'s circuit-switched communication device, a method for bridging a contact comprising:
- (a) setting up a first contact with the first subscriber'"'"'s circuit-switched communication device;
(b) in response to step (a), the at least one of a switch and server generating a first contact message related to the first contact and comprising a source address other than a source address of the at least one proxy server and a destination address;
(c) applying the following rules to the first contact message;
(C1) when a source address of a contact message corresponds to a proxy server, not bridging a corresponding contact to a subscriber'"'"'s packet-switched communication device; and
(C2) when the source address of the contact message does not correspond to a proxy server, bridging the corresponding contact to the subscriber'"'"'s packet-switched communication device;
(d) in response to step (c), bridging the first contact to the first subscriber'"'"'s packet-switched communication device;
(e) receiving, from the at least one proxy server, a second contact message related to the first contact message and comprising a source address of the at least one proxy server and a destination address of at least one of the communication devices associated with the first subscriber;
(f) applying the rules (C1) and (C2); and
(g) in response to step (f), not bridging a contact associated with the second contact message to the first subscriber'"'"'s packet-switched communication device.

Abstract
The present invention is directed to a telecommunications system 100 for routing a contact to a selected address, comprising (a) an input for receiving a contact message comprising a source address and a destination address of a subscriber communication device 116 associated with a subscriber and (b) mobility agent 160 for determining whether or not the source address in the contact message corresponds to a proxy server 128 and, when the source address corresponds to a proxy server 128, causing the contact not to be routed to a selected address and, when the source address does not correspond to a proxy server 128, causing the contact to be routed to the selected address.

14. A telecommunications system, comprising:
-
a plurality of circuit-switched communication devices corresponding to a plurality of subscribers, a plurality of packet-switched communication devices corresponding to the plurality of subscribers, and at least one of a switch and server, wherein the at least one of a switch and server is in communication with a packet-switched network comprising a plurality of proxy servers and a circuit-switched network, wherein at least one proxy server has a set of predefined rules directing a contact for a first subscriber to the first subscriber'"'"'s circuit-switched communication device, wherein the at least one of a switch and server generates and sends a first contact message related to a first contact and comprising a source address other than a source address associated with the at least one proxy server and a destination address and wherein the at least one of a switch and server comprises a mobility agent operable to; (a) apply the following rules; (a1) when a source address of a selected contact message corresponds to a proxy server, not bridging the contact to a selected subscriber'"'"'s packet-switched communication device; and (a2) when the source address of a selected contact message does not correspond to a proxy server, bridging the contact to the selected subscriber'"'"'s packet-switched communication device; (b) receive a second contact message related to the first contact message and comprising a source address of the at least one proxy server and a destination address of at least one of the communication devices associated with the first subscriber; (c) apply the rules (a1) and (a2); and (d) in response, not bridge a second contact associated with the second contact message to the first subscriber'"'"'s packet-switched communication device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. In a telecommunications system comprising a plurality of circuit-switched communication devices corresponding to a plurality of subscribers, a plurality of packet-switched communication devices corresponding to the plurality of subscribers, and at least one of a switch and server, the at least one of a switch and server being in communication with a packet-switched network comprising a plurality of proxy servers and a circuit-switched network and at least one of the proxy servers having a set of predefined rules requiring any contact for a first subscriber from a second subscriber not to be directed to the first subscriber'"'"'s circuit-switched device, a method comprising:
-
(a) determining whether contact termination requires a selected contact to be bridged to a selected subscriber'"'"'s packet-switched communication device served by the at least one proxy server by applying the following rules; (A1) when a source address of a contact message corresponds to a proxy server, not bridging a corresponding contact to a subscriber'"'"'s packet-switched communication device; and (A2) when the source address of the contact message does not correspond to a proxy server, bridging the corresponding contact to the subscriber'"'"'s packet-switched communication device; and (b) when contact termination requires the selected contact to be bridged to a selected subscriber'"'"'s packet-switched communication device served by the at least one proxy server, applying the following rules; (b1) not activating a ringer in the selected subscriber'"'"'s circuit-switched communication device; and (b2) bridging the contact to the selected subscriber'"'"'s packet-switched communication device, thereby permitting the at least one proxy server to apply user defined rules; and (c) when contact termination does not require the selected contact to be bridged to a selected subscriber'"'"'s packet-switched communication device served by the at least one proxy server, not applying rules (b1) and (b2). - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
