Abstract

A method for communication in an environment including a circuit-switched network and a packet-switched network, both of which include a respective connectivity layer including one or more switching elements and a respective service layer including one or more service platforms. A request is accepted to set up a call for a communication terminal associated with one or more of the networks. The call is established responsively to the request via one or more of the switching elements. At least one service platform in the service layer of the circuit-switched network is invoked to provide a first ancillary call service to the call, and at least one second service platform in the service layer of the packet-switched network is invoked to provide a second ancillary call service to the call.

Claims

1. A method for communication, comprising:

in an environment comprising a circuit-switched network, which comprises a first connectivity layer comprising one or more first switching elements and a first service layer comprising one or more first service platforms, and a packet-switched network, which comprises a second connectivity layer comprising one or more second switching elements and a second service layer comprising one or more second service platforms, accepting a request to set up a call for a communication terminal associated with one or more of the networks;

establishing the call responsively to the request via one or more of the switching elements; and

invoking at least one of the first service platforms in the first service layer of the circuit-switched network to provide a first ancillary call service to the call, and at least one of the second service platforms in the second service layer of the packet-switched network to provide a second ancillary call service to the call.

2. The method according to claim 1, wherein the circuit-switched network operates in accordance with a signaling system 7 (SS7) protocol.

3. The method according to claim 1, wherein the one of the first service platforms comprises a service control point (SCP) and wherein the first ancillary call service comprises an intelligent network (IN) service.

4. The method according to claim 1, wherein the packet-switched network comprises an Internet Protocol (IP) network, and wherein the one of the second service platforms comprises a Session Initiation Protocol (SIP) Application Server (AS).

5. The method according to claim 1, wherein the packet-switched network comprises an IP Multimedia Subsystem (IMS) network.

6. The method according to claim 1, wherein the networks comprise a Long-Term Evolution (LTE) network.

7. The method according to claim 1, wherein the first and second ancillary call services are selected from a group of service types consisting of a payment-related service, an abbreviated dialing service, a Virtual Private Network (VPN) service, a private dialing plan, a shared directory service, an Interactive Voice Response (IVR) service, a call screening service, a multiple call appearance service, an Automatic Call Distribution (ACD) service and an attendant service.

8. A convergence server, comprising:

first and second network interfaces, which are respectively arranged to communicate with a circuit-switched network and a packet-switched network, wherein the circuit-switched network comprises a first connectivity layer comprising one or more first switching elements and a first service layer comprising one or more first service platforms, and wherein the packet-switched network comprises a second connectivity layer comprising one or more second switching elements and a second service layer comprising one or more second service platforms; and

a processor, which is arranged to accept a request to set up a call for a communication terminal associated with one or more of the networks, to establish the call responsively to the request via one or more of the switching elements, and to invoke at least one of the first service platforms in the first service layer of the circuit-switched network to provide a first ancillary call service to the call, and at least one of the second service platforms in the second service layer of the packet-switched network to provide a second ancillary call service to the call.

9. The convergence server according to claim 8, wherein the circuit-switched network operates in accordance with a signaling system 7 (SS7) protocol.

10. The convergence server according to claim 8, wherein the one of the first service platforms comprises a service control point (SCP) and wherein the first ancillary call service comprises an intelligent network (IN) service.

11. The convergence server according to claim 8, wherein the packet-switched network comprises an Internet Protocol (IP) network, and wherein the one of the second service platforms comprises a Session Initiation Protocol (SIP) Application Server (AS).

12. The convergence server according to claim 8, wherein the packet-switched network comprises an IP Multimedia Subsystem (IMS) network.

13. The convergence server according to claim 8, wherein the networks comprise a Long-Term Evolution (LTE) network.

14. The convergence server according to claim 8, wherein the first and second ancillary call services are selected from a group of service types consisting of a payment-related service, an abbreviated dialing service, a Virtual Private Network (VPN) service, a private dialing plan, a shared directory service, an Interactive Voice Response (IVR) service, a call screening service, a multiple call appearance service, an Automatic Call Distribution (ACD) service and an attendant service.

15. A communication system, comprising:

a circuit-switched network, which comprises a first connectivity layer comprising one or more first switching elements and a first service layer comprising one or more first service platforms;

a packet-switched network, which comprises a second connectivity layer comprising one or more second switching elements and a second service layer comprising one or more second service platforms; and

a convergence server, which is connected to the circuit-switched and packet-switched networks and is arranged to accept a request to set up a call for a communication terminal associated with one or more of the networks, to establish the call responsively to the request via one or more of the switching elements, and to invoke at least one of the first service platforms in the first service layer of the circuit-switched network to provide a first ancillary call service to the call, and at least one of the second service platforms in the second service layer of the packet-switched network to provide a second ancillary call service to the call.

16. The system according to claim 15, wherein the circuit-switched network operates in accordance with a signaling system 7 (SS7) protocol.

17. The system according to claim 15, wherein the one of the first service platforms comprises a service control point (SCP) and wherein the first ancillary call service comprises an intelligent network (IN) service.

18. The system according to claim 15, wherein the packet-switched network comprises an Internet Protocol (IP) network, and wherein the one of the second service platforms comprises a Session Initiation Protocol (SIP) Application Server (AS).

19. The system according to claim 15, wherein the packet-switched network comprises an IP Multimedia Subsystem (IMS) network.

20. The system according to claim 15, wherein the networks comprise a Long-Term Evolution (LTE) network.

21. The system according to claim 15, wherein the first and second ancillary call services are selected from a group of service types consisting of a payment-related service, an abbreviated dialing service, a Virtual Private Network (VPN) service, a private dialing plan, a shared directory service, an Interactive Voice Response (IVR) service, a call screening service, a multiple call appearance service, an Automatic Call Distribution (ACD) service and an attendant service.
