Abstract

An improved system and method for high penetration notification is disclosed. Whereas conventional telecommunications systems invoke wireline trunking resources to transfer calling number information to the transmitter for wireless transmission to a called subscriber, the system and method of the present invention avoids allocation of the trunking resources by incorporating the calling number information into existing non-trunked information transference protocols.

Claims

1. In a telecommunications system communicating with a plurality of mobile terminals, a calling party attempting to contact a respective one of said mobile terminals, circuitry within said system for forwarding caller information to said one mobile terminal, said circuitry comprising:

a gateway mobile switching center for receiving a message from said calling party, said gateway mobile switching center upon receiving said message from said calling party forwarding a first routing information request to a home location register associated with said system;

a mobile switching center associated with said one mobile terminal, said home location register upon receiving said first routing information request forwarding a second routing information request to said mobile switching center, said first and second routing information requests including said caller information therein; and

an attached/detached database, within said mobile switching center, said database comprising a plurality of connection status flags associated with a corresponding plurality of said mobile terminals associated with said mobile switching center, said plurality of mobile terminals including said one mobile terminal,

whereby, when said connection status flag associated with said one mobile terminal indicates said one mobile terminal is detached from said mobile switching center, said caller information is transmitted to said one mobile terminal.

2. The system according to claim 1, further comprising:

a high penetration notification node, in communication with said mobile switching center.

3. The system according to claim 2, wherein said high penetration node is attached to said mobile switching center.

4. The system according to claim 2, wherein said high penetration node is attached to a satellite in communication with said mobile switching center and said mobile terminal.

5. The system according to claim 2, wherein said node is invoked if said one mobile terminal user is a high penetration node subscriber.

6. The system according to claim 2, wherein said node is invoked if the load on said mobile switching center is below a given threshold.

7. The system according to claim 1, wherein said first and second routing information requests are in Mobile Application Part protocol.

8. The system according to claim 7, wherein said first routing information request to said home location register is a Send Routing Information command.

9. The system according to claim 7, wherein said second routing information request to said mobile switching center is a Provide Roaming Number command.

10. The system according to claim 1, wherein each of said connection status flags in said database is a Boolean value, where said flag associated with said one mobile terminal is set when said one mobile terminal is detached from said mobile switching center.

11. The system according to claim 1, wherein each of said connection status flags in said database is a 2 bit value.

12. The system according to claim 11, wherein said flag includes an implicit detachment flag therein.

13. The system according to claim 11, wherein said flag includes an explicit detachment flag therein.

14. The system according to claim 1, further comprising:

a display means, attached to said one mobile terminal, for displaying said caller information thereon.

15. The system according to claim 14, wherein said caller information includes a return telephone number associated with said calling party.

16. The system according to claim 1, further comprising a storage means, within said one mobile terminal, for storing said caller information therein.

17. The system according to claim 16, wherein said caller information includes a return telephone number associated with said calling party.

18. A method for forwarding calling party information to a mobile terminal within a telecommunications system, said system including a gateway mobile switching center, a mobile switching center having an attached/detached database therein, and a home location register, said mobile switching center being associated with said mobile terminal, said method comprising the steps of:

(a) receiving said calling party information at said gateway mobile switching center;

(b) sending, from said gateway mobile switching center to said home location register, a first routing information request, said first routing information request including said calling party information therein;

(c) receiving, at said home location register, said first routing information request, and sending, to said mobile switching center associated with said mobile terminal, a second routing information request, said second routing information request including said calling party information therein;

(d) retrieving, within said attach/detach database within said mobile switching center, a connection status flag value associated with said mobile terminal; and

(e) transmitting, from said mobile switching center to said mobile terminal, a signal including said calling party information therein,

whereby said mobile terminal receives said calling party information.

19. The method according to claim 18, wherein said signal is a high penetration notification signal.

20. The method according to claim 18, wherein said step of transmitting comprises:

transmitting said signal from said mobile switching center to a satellite and from said satellite to said mobile terminal.

21. The method according to claim 18, wherein said first and second routing information requests are in Mobile Application Part protocol.

22. The method according to claim 21, wherein said first routing information request to said home location register is a Send Routing Information command.

23. The method according to claim 21, wherein said second routing information request to said mobile switching center is a Provide Roaming Number command.

24. The method according to claim 18, further comprising the step of:

displaying, at said mobile terminal, said calling party information.

25. The method according to claim 24, wherein said calling party information includes a return telephone number associated with said calling party.

26. The method according to claim 18, further comprising the step of:

storing, within said mobile terminal, said calling party information.

27. The method according to claim 26, wherein said calling party information includes a return telephone number associated with said calling party.
