Abstract

A system for establishing a communication link between a caller and a mobile communication device that includes a mobile telephone and a paging device capable of receiving information transmitted from a paging network. In addition to the mobile communication device, the system includes a telephone network, a first mobile switching center, a conference bridge, a paging network, and a second mobile switching center. The first mobile switching center receives a telephone call transmitted over the telephone network using an identification number of the mobile telephone. If the mobile communication device is not located in the area covered by the mobile switching center, the mobile switching center forwards the received telephone call to a conference bridge using a bridge number assigned to the mobile communication device. The conference bridge receives the forwarded telephone call and transmits an identification number of the paging device in the mobile communication device to the paging network. The paging network receives the paging number and transmits a page to the paging device using the paging number. In response to the page, the mobile communication device calls the conference bridge using a bridge callback number. In response to the callback from the mobile communication device, the conference bridge connects the caller to the mobile telephone in the mobile communication device.

Claims

1. A system for establishing a communication link between a caller and a mobile communication device including a mobile telephone and a paging device, comprising:

means for generating a first signal in response to a telephone call from said caller, said first signal including an identification number of said mobile telephone;

means for transmitting said first signal to a first mobile switching center, said first mobile switching center comprising;

means for receiving said first signal;

means responsive to said first signal for generating a second signal, said second signal including said identification number of said mobile telephone and a conference bridge number corresponding to said mobile telephone; and

means for transmitting said second signal;

a conference bridge corresponding to said conference bridge number comprising;

means for receiving said second signal;

means responsive to said second signal for generating a third signal, said third signal including a paging network number and an identification number of said paging device; and

means for transmitting said third signal;

a paging network corresponding to said paging network number comprising;

means for receiving said third signal;

means responsive to said third signal for generating a page signal including said identification number of said paging device; and

means for transmitting said page signal to said mobile communication device;

said mobile communication device comprising;

means for receiving said page signal;

means responsive to said page signal for generating a fourth signal including a conference bridge callback number; and

means for transmitting said fourth signal;

a second mobile switching center including means for receiving and retransmitting said fourth signal to said conference bridge;

said conference bridge further comprising;

means for receiving said retransmitted fourth signal; and

means responsive to said fourth signal for connecting said caller to said mobile communication device.

2. A system according to claim 1 wherein said means for receiving said second signal in said conference bridge comprises an in-dial port.

3. A system according to claim 2, wherein said third signal and said page signal each further include a port number of said in-dial port.

4. A system according to claim 1, wherein said third signal and said page signal each further include a bridge callback number.

6. A system according to claim 1, said conference bridge being included in said mobile switching center.

7. A system according to claim 1, said conference bridge being included in said means for transmitting said first signal to a first mobile switching center.

8. A system according to claim 1, wherein the caller can call the subscriber using the same identification number of the mobile telephone regardless of whether the subscriber is at a home region covered by the first mobile switching center or at a remote region covered by the second mobile switching center.

5. A system for establishing a communication link between a caller and a mobile communication device including a mobile telephone and a paging device, comprising:

means for generating a first signal in response to a telephone call from said caller, said first signal including an identification number of said mobile telephone;

means for transmitting said first signal to a first mobile switching center, said first mobile switching center comprising;

means for receiving said first signal;

means responsive to said first signal for generating a second signal, said second signal including said identification number of said mobile telephone and a conference bridge number corresponding to said mobile telephone; and

means for transmitting said second signal;

a conference bridge corresponding to said conference bridge number comprising;

means for receiving said second signal;

means responsive to said second signal for generating a third signal, said third signal including a paging network number and an identification number of said paging device; and

means for transmitting said third signal;

a paging network corresponding to said paging network number comprising;

means for receiving said third signal;

means responsive to said third signal for generating a page signal including said identification number of said paging device; and

means for transmitting said page signal to said mobile communication device;

said mobile communication device comprising;

means for receiving said page signal;

means responsive to said page signal for generating a fourth signal including a conference bridge callback number; and

means for transmitting said fourth signal;

a second mobile switching center including means for receiving and retransmitting said fourth signal to said conference bridge;

said conference bridge further comprising;

means for receiving said retransmitted fourth signal; and

means responsive to said fourth signal for connecting said caller to said mobile communication device;

said conference bridge further comprising;

means for generating a fifth signal if said fourth signal is not received within a predetermined amount of time after said third signal is transmitted, said fifth signal including said paging network number, said identification number of said mobile communication device, and a kill signal; and

means for transmitting said fifth signal;

said paging network further comprising;

means for receiving said fifth signal;

means for generating a second page signal including said kill signal and said identification number of said mobile communication device; and

means for transmitting said second page signal; and

said mobile communication device further comprising;

means for receiving said second page signal; and

means for prohibiting transmission of said fourth signal in response to said second page signal.

9. A communication system comprising:

means for generating a communication signal;

means for receiving the communication signal and generating a first signal in response to the communication signal;

a first mobile switching center coupled to the receiving means;

a conference bridge coupled to the first mobile switching center;

a paging network coupled to the conference bridge;

means for transmitting said first signal to the first mobile switching center, said first mobile switching center comprising;

at least one first input port and at least one first output port;

means for receiving said first signal at the one first input port;

means responsive to said first signal for generating a second signal, said second signal including a conference bridge number corresponding to the conference bridge; and

means for transmitting said second signal through the one first output port;

said conference bridge comprising;

at least one second input port and at least one second output port;

means for receiving said second signal at the one second input port;
