Abstract

A system and method of using two-way paging to establish communications with a mobile party having a Personal Telephone Number. The mobile party uses the two-way pager to transmit call control parameters which are used by the telephone network to route calls directed to the party'"'"'s PTN. The mobile party may also use the pager to transmit subsequent routing parameters which are used by the network to reroute calls which have been previously routed. The subsequent routing of a call may be performed at any time following a previous routing, even after the call has received answer supervision.

Claims

1. A method for routing a call that is initiated at a first communication device and directed to a telephone number, comprising the steps of:

a) routing the call to a second communication device;

b) receiving one or more subsequent call control parameters, said subsequent parameters originating from a two-way pager and describing one or more characteristics of a third communication device including bandwidth; and

c) routing the call to said third communication device.

2. A method according to claim 1, wherein prior to said step of routing the call to a second communication device, the method further comprises the step of receiving one or more call control parameters, said parameters originating from a two-way pager and being associated with a second communication device.

3. A method according to claim 1, further comprising the step of using one or more of said subsequent call control parameters, other than a terminating station identifier, to define a parameter of the call as completed to said third communication device.

4. A method according to claim 1, wherein the step of routing the call to said second communication device comprises the step of:

using a network control point to route the call to said second communication device.

5. A method according to claim 1, wherein the step of routing the call to said second communication device comprises the step of:

using an adjunct to route the call to said second communication device.

6. A method according to claim 1, wherein the step of routing the call to said third communication device is performed after answer supervision has been received from said second communication device.

7. A method according to claim 6, wherein the step of routing the call to said second communication device comprises the step of:

using a network control point to route the call to said second communication device.

8. A method according to claim 6, wherein the step of routing the call to said second communication device comprises the step of:

using an adjunct to route the call to said second communication device.

9. The invention of claim 1, wherein said call control parameters are selected from the group consisting of a bandwidth, a protocol, and a special instruction.

10. A system for routing a call that is initiated at a first communication device and directed to a telephone number, comprising:

a) means for routing the call to a second communication device;

b) means for receiving one or more subsequent call control parameters, said subsequent parameters originating from a two-way pager and describing one or more characteristics of a third communication device including bandwidth; and

c) means for routing the call to said third communication device.

11. A system according to claim 10, further comprising:

means for receiving one or more call control parameters prior to routing the call to a second communication device, said parameters originating from a two-way pager and being associated with a second communication device.

12. A system according to claim 10, further comprising:

means for using one or more of said subsequent call control parameters, other than a terminating station identifier, to define a parameter of the call as completed to said third communication device.

13. A system according to claim 11, wherein said means for receiving one or more call control parameters and said means for receiving one or more subsequent call control parameters are the same.

14. A system according to claim 10, wherein said means for routing the call to a second communication device and said means for routing the call to a third communication device are the same.

15. A system according to claim 11, wherein said means for receiving one or more call control parameters and said means for receiving one or more subsequent call control parameters are the same, and said means for routing the call to said second communication device and said means for routing the call to said third communication device are the same.

16. The invention of claim 10, wherein said call control parameters are selected from the group consisting of a bandwidth, a protocol, and a special instruction.

17. A system for routing call that is initiated at a first communication device and directed to a telephone number, comprising:

a) a two-way paging system for receiving one or more subsequent call control parameters, said subsequent parameters originating from a two-way pager and describing one or more characteristics of a third communication device including bandwidth; and

b) a telephone network for i) routing the call to a second communication device, and (ii) routing the call to said third communication device only after said telephone network receives said subsequent parameters from said two-way pager.

18. A system according to claim 17, wherein said telephone network includes means for using one or more of said subsequent call control parameters, other than a terminating station identifier, to define a parameter of the call as completed to said third communication device.

19. The invention of claim 17, wherein said call control parameters are selected from the group consisting of a bandwidth, a protocol, and a special instruction.

20. A system for routing a call that is initiated at a first communication device and directed to a telephone number, comprising:

a) means for (i) retrieving a pager code for the subscriber, and (ii) initiating a page of the subscriber, both in response to the initiation of the call;

b) means for receiving one or more call control parameters, said call control parameters being originated from a two-way pager as a response to said page, and said parameters being associated with a second communication device;

c) means for routing the call to said second communication device;

d) means for receiving one or more subsequent call control parameters, said subsequent call control parameters being originated from said two-way pager and describing one or more characteristics of a third communication device including bandwidth; and

e) means for routing the call to said third communication device.

21. A system according to claim 20, further comprising:

means for using one or more of said subsequent call control parameters, other than a terminating station identifier, to define a parameter of the call as completed to said third communication device.

22. The invention of claim 20, wherein said call control parameters are selected from the group consisting of a bandwidth, a protocol, and a special instruction.

23. A method for routing a call that is initiated at a first communication device and directed to a telephone number, comprising the steps of:

a) routing the call to a second communication device;

b) receiving one or more subsequent call control parameters, said subsequent parameters originating from a two-way pager and describing one or more characteristics of a third communication device including bandwidth;

c) routing the call to said third communication device; and

d) using one or more of said subsequent call control parameters, other than a terminating station identifier, to define a parameter of the call as completed to said third communication device.

24. A method according to claim 23, wherein the step of routing the call to said third communication device is performed after answer supervision has been received from said second communication device.

25. The invention of claim 23, wherein said call control parameters are selected from the group consisting of a bandwidth, a protocol, and a special instruction.
