Abstract

The present invention is a service control point (SCP) for use in a telecommunications network, and in particular, as a component of a telecommunications signaling system. The SCP includes multiple databases which allow routing plans to be stored and implemented. The SCP is operable to accept queries from switches for routing information. The SCP is further operable to reply to these queries with information identifying a connection as opposed to a routing number.

Claims

1. A method of operating a database system wherein a telecommunications network element transmits a first signaling message associated with a call to the database system, the method comprising:

receiving the first signaling message into the database system from the network element;

selecting a plurality of alternative call path connections for the call associated with the first signaling message;

generating a second signaling message identifying the alternative call path connections; and

transmitting the second signaling message from the database system to the network element.

2. The method of claim 1 wherein the network element is a switch.

3. The method of claim 1 wherein the database system is a Service Control Point (SCP).

4. The method of claim 1 wherein the first and second signaling messages are in Signaling System #7 (SS7) format.

5. The method of claim 1 wherein the call is an "800" call.

6. The method of claim 1 wherein the call is a virtual network call.

7. The method of claim 1 wherein at least one of the alternative call path connections is a trunk and switch combination.

8. The method of claim 1 wherein at least one of the alternative call path connections is a DS0 circuit.

9. The method of claim 1 wherein at least one of the alternative call path connections is a virtual circuit.

10. A database system for processing a first signaling message associated with a call in a telecommunications network wherein the first signaling message is transmitted from a network element to the database system, the database system comprising:

an interface operable to receive the first signaling message from the network element and transmit a second signaling message to the network element;

a memory containing routing information which includes information identifying a plurality of connections; and

a processor coupled to the interface and the memory operable to process the first signaling message, determine a plurality of alternative path connections for the call, and generate the second signaling message identifying the alternative call path connections.

11. The system of claim 10 wherein the network element is a switch.

12. The system of claim 10 wherein the database system is a Service Control Point (SCP).

13. The system of claim 10 wherein the first and second signaling messages are in Signaling System #7 (SS7) format.

14. The system of claim 10 wherein the routing information is comprised of a routing tree node, a plurality of decision nodes, and a plurality of destination nodes.

15. The system of claim 14 wherein the decision nodes are comprised of at least a point of origin node, a time node, and a dialed number node.

16. The system of claim 14 wherein the destination nodes can yield a plurality of prioritized connections for the call.

17. A Service Control Point (SCP) for processing a first Transaction Capabilities Application Part (TCAP) signaling message associated with a call in a telecommunications network, wherein a switch transmits the first TCAP signaling message to the SCP, the SCP comprising:

an interface means for receiving the first TCAP signaling message from the switch and for transmitting a second TCAP signaling message to the switch;

a signaling means for applying Signaling System #7 (SS7) processing to the first and second TCAP signaling messages; and

a processing means for determining a prioritized list of alternative path connections for the call associated with the first TCAP signaling message and for generating the second TCAP signaling message wherein the second TCAP signaling message identifies the alternative call path connections.
