Abstract

A method in one example is directed to utilizing a WIN (wireless intelligent network) and a SCP (service control point) to intelligently route mobile originated calls destined for a private network, from current serving MSC (mobile switching center) to a designated gateway MSC.

Claims

1. A method comprising:

utilizing a WIN (wireless intelligent network) and a SCP (service control point) to intelligently route mobile originated calls destined for a private network, from current serving MSC (mobile switching center) to a designated gateway MSC.

2. The method according to claim 1, wherein the designated gateway MSC has direct connect trunking facilities to the private network.

3. The method according to claim 2, wherein, after receiving a call from the serving MSC, the gateway MSC routing the call directly to the private network.

4. The method according to claim 2, wherein the private network carries the call to a final destination within the private network (local, long distance, or international).

5. The method according to claim 1, wherein routing from the serving MSC to the designated gateway MSC occurs over one of dedicated facilities or via the PSTN.

6. The method according to claim 5, wherein the dedicated facilities are one of ISUP or ISDN based.

7. The method according to claim 1, wherein the serving MSC supports a predetermined type of WIN (wireless intelligent network) triggers.

8. The method according to claim 7, wherein the SCP supports receipt of the triggers along with application logic to redirect calls, made at the mobile terminal, in a serving MSC to a gateway MSC for final routing.

9. A method comprising:

dialing an access number from a mobile terminal, the access number being received by a serving MSC (mobile switching center);

launching a trigger from the serving MSC to an SCP based application;

determining, at the SCP based application, from the trigger that the destination is international and returning a TRN (temporary routing number) to the serving MSC;

sending the TRN from the serving MSC to a gateway MSC via a PSTN (public switched telephone network);

sending, from the serving MSC, a SPDS (specific party digit string) trigger to a SCP (service control point) in the gateway MSC;

determining, at the SCP, that the received SPDS trigger is a special SCPDS (specific called party digit string) trigger and performing a table look up on a CPN (calling party number), the SCP making an internal association with the CPN and dialed digits of the international access number; and

returning one of the original dialed digits or translated digits based on the original digits, when the SCP finds a match for the CPN;

routing, by the gateway MSC, the original dialed digits to a PBX (private branch exchange) via PRI (private network).

10. The method according to claim 9, wherein the designated gateway MSC has direct connect trunking facilities to the private network.

11. The method according to claim 10, wherein, after receiving a call from the serving MSC, the gateway MSC routing the call directly to the private network.

12. The method according to claim 10, wherein the private network carries the call to a final destination within the private network (local, long distance, or international).

13. The method according to claim 9, wherein routing from the serving MSC to the designated gateway MSC occurs over one of dedicated facilities or via the PSTN.

14. The method according to claim 13, wherein the dedicated facilities are one of ISUP or ISDN based.

15. The method according to claim 9, wherein the serving MSC supports a predetermined type of WIN (wireless intelligent network) triggers.

16. The method according to claim 15, wherein the SCP supports receipt of the triggers along with application logic to redirect calls, made at the mobile terminal, in a serving MSC to a gateway MSC for final routing.

17. An apparatus comprising:

a WIN (wireless intelligent network) operatively coupled to a SCP (service control point) to intelligently route mobile originated calls destined for a private network, from a current serving MSC (mobile switching center) to a designated gateway MSC.

18. The apparatus according to claim 17, wherein the designated gateway MSC has direct connect trunking facilities to the private network.

19. The apparatus according to claim 17, wherein routing from the serving MSC to the designated gateway MSC occurs over one of dedicated facilities or via the PSTN.

20. The method according to claim 17, wherein the dedicated facilities are one of ISUP or ISDN based.
