Claim 7

A call diversion method for use in an integrated telecommunications network having a packet-switched network (PSN) portion and a circuit-switched network (CSN) portion, wherein a service node including at least one of a Service Control Point (SCP) and a Service Data Point (SDP) is coupled via an interface to the PSN portion, the PSN portion including a call-originating entity, a served entity and a switching entity, the call diversion method comprising the steps of: sending a first setup message from the call-originating entity to the switching entity pursuant to placing a call to the served entity; thereafter, sending a second setup message from the switching entity to the served entity and establishing a first connection therebetween; responsive to the second setup message, sending a service message from the served entity to the service node via the interface; based on the service message, executing by the service node a service logic portion associated with the service; sending a return result from the service node to the served entity, the return result comprising an address of a diverted-to entity to which the call from the call-originating entity is to be diverted; transmitting a call re-routing request from the served entity to the switching entity, the call re-routing request including an indication of the return result from the service node; responsive to the call re-routing request, sending a call re-routing request answer from the switching entity to the served entity; thereafter, releasing the first connection between the switching entity and the served entity; admitting the diverted-to entity by the switching entity; and establishing a second connection between the call-originating entity and the diverted-to entity.

Claim 8

The call diversion method as set forth in claim 5 , wherein the diverted-to entity comprises a mobile station disposed in the CSN portion.

Claim 9

The call diversion method as set forth in claim 5 , wherein the diverted-to entity comprises a fixed telephone disposed in the CSN portion.

Claim 10

The call diversion method as set forth in claim 5 , wherein the diverted-to entity comprises an H.323-based terminal disposed in the PSN portion.

Claim 11

The call diversion method as set forth in claim 5 , wherein the diverted-to entity is selected from the group consisting of a Personal Digital Assistant, a smart phone, a laptop computer, a personal computer, a palmtop computer, a pager, and an Information Appliance.

Claim 12

A call diversion method for use in an integrated telecommunications network having a packet-switched network (PSN) portion and a circuit-switched network (CSN) portion, wherein a service node including at least one of a Service Control Point (SCP) and a Service Data Point (SDP) is coupled via an interface to the PSN portion, the PSN portion including a call-originating entity, a diverting entity and a switching entity, the call diversion method comprising the steps of: sending a first setup message from the call-originating entity to the switching entity pursuant to placing a call to the diverting entity; thereafter, sending a second setup message from the switching entity to the diverting entity and establishing a first connection therebetween; responsive to the second setup message, transmitting a call re-routing request from the diverting entity to the switching entity; based on the call re-routing request, sending a service message from the switching entity to the service node via the interface; executing by the service node a service logic portion associated with the service; sending a return result from the service node to the switching entity, the return result comprising an address of a diverted-to entity to which the call from the call-originating entity is to be diverted; sending a call re-routing request answer from the switching entity to the diverting entity; thereafter, releasing the first connection between the switching entity and the diverting entity; admitting the diverted-to entity by the switching entity; and establishing a second connection between the call-originating entity and the diverted-to entity.

Claim 13

A call diversion method for use in an integrated telecommunications network having a packet-switched network (PSN) portion and a circuit-switched network (CSN) portion, wherein a service node including at least one of a Service Control Point (SCP) and a Service Data Point (SDP) is coupled via an interface to the PSN portion, the PSN portion including a call-originating entity, a diverting entity and a switching entity, the call diversion method comprising the steps of: sending a first setup message from the call-originating entity to the switching entity pursuant to placing a call to the diverting entity; thereafter, sending a second setup message from the switching entity to the diverting entity and establishing a first connection therebetween; responsive to the second setup message, transmitting a call re-routing request from the diverting entity to the switching entity; based on the call re-routing request, sending a service message from the switching entity to the service node via the interface; executing by the service node a service logic portion associated with the service; sending a return result from the service node to the switching entity, the return result comprising an address of a diverted-to entity to which the call from the call-originating entity is to be diverted; sending a call re-routing request answer from the switching entity to the diverting entity; thereafter, releasing the first connection between the switching entity and the diverting entity; admitting the diverted-to entity by the switching entity; and establishing a second connection between the call-originating entity and the diverted-to entity.
