Abstract

A call placed by a calling party from within the local office or campus area served by an intelligent PBX of a called party who is a subscriber to a personal reach service is held at that PBX for determination of whether the called party/subscriber is within or outside the local area served by the PBX. This determination is made using two-way paging technology through which a pager-carrying called party/subscriber is determined to be within the local area if the two-way pager carried by the called party/subscriber is registered within the area. If the called party/subscriber is determined to be within the local area, then a local page is broadcast to the called party/subscriber and a return call to the PBX by the called party/subscriber is bridged with the call being held from the calling party at the PBX. If the called party/subscriber is determined to be outside the local area, then the calling party'"'"'s call is connected over the telephone network to the called party/subscriber'"'"'s personal reach service network platform. A nationwide page is broadcast and a return call from the called party/subscriber to the network platform is bridged with the calling party'"'"'s call to complete the connection between the calling and called parties.

Claims

1. A method for use in completing a telephone call to a called party/subscriber to a personal reach telephone service placed by a calling party who is local to a home PBX associated with that called party/subscriber, the method comprising the steps of:

receiving the calling party'"'"'s call at the home PBX;

determining whether the called party/subscriber is within an area local to the home PBX at the time the calling party'"'"'s call is received at the home PBX;

if the called party/subscriber is determined to be within the area local to the home PBX and the calling party has dialed a personal reach telephone number associated with the called party/subscriber on the personal reach telephone service, converting the personal reach telephone number to a local extension number on the home PBX and initiating connection of the call from the PBX to the local extension number; and

if the called party/subscriber is determined to be outside the area local to the home PBX and the calling party has dialed a local extension number associated with the called party/subscriber on the home PBX, converting the dialed local extension number to the personal reach telephone number associated with the called party/subscriber and initiating connection of the call from the PBX to the personal reach telephone number.

2. The method of claim 1 wherein the step of determining whether the called party/subscriber is within an area local to the home PBX comprises the step of using two-way paging technology to determine whether a pager associated with the called party/subscriber is within the area local to the home PBX.

3. The method of claim 1 further comprising the steps of:

if the called party/subscriber is determined to be within the area local to the home PBX and the calling party has dialed the called party/subscriber'"'"'s personal reach telephone number, upon initiating connection of the call from the PBX to the local extension number also locally paging the called party/subscriber within the area local to the home PBX to alert the called party/subscriber that a telephone call is waiting;

if the called party is responsive to the local page, receiving a return telephone call from the called party/subscriber at the home PBX; and

bridging together at the home PBX the telephone call from the calling party and the called party/subscriber'"'"'s return telephone call.

4. The method of claim 1 further comprising the step of ringing a telephone at the called party/subscriber'"'"'s local extension number on the local PBX if the called party/subscriber is determined to be within the area local to the home PBX and the calling party has dialed the personal reach telephone number.

5. The method of claim 1 further comprising the steps of:

if the called party/subscriber is determined to be outside the area local to the home PBX and the calling party has dialed the called party/subscriber'"'"'s local extension number, completing connection of the call from the PBX to the personal reach telephone number to a personal reach system network platform associated with the called party/subscriber which has meet-me bridging capabilities; and

initiating a nationwide page to the called party/subscriber.

6. The method of claim 5 further comprising the steps of:

if the called party is responsive to the nationwide page, receiving a return telephone call from the called party/subscriber at the personal reach system network platform; and

bridging together the return call and the calling party'"'"'s call at the personal reach system network platform.

7. The method of claim 2 wherein the step of determining whether the pager associated with the called party/subscriber is within an area local to the home PBX comprises the step of determining whether the pager is registered in the area local to the PBX.

8. The method of claim 3 further comprising the step of connecting the call from the calling party to a voice mailbox associated with the called party/subscriber if the called party/subscriber is not responsive to the local page within a predetermined time.

9. The method of claim 5 further comprising the step of connecting the call from the calling party to a voice mailbox associated with the called party/subscriber if the called party/subscriber is not responsive to the nationwide page with a predetermined time.

10. In a personal reach telephone system in which a call from a calling party to a called party/subscriber'"'"'s Personal Reach Service (PRS) telephone number is bridged to a return call placed by the called party in response to a page to a pager associated with the called party which page indicates to the called party/subscriber that a call is waiting, a meet-me bridge being located in a network platform of the personal reach service telephone system associated with the called party/subscriber, the called party/subscriber also being associated with a home PBX having meet-me bridging capabilities, a method comprising the steps of:

receiving a call at the called party/subscriber'"'"'s home PBX for the called party/subscriber from a calling party who is also local to the home PBX;

determining whether the called party/subscriber is within an area local to the home PBX when the call from the called party/subscriber is received;

if the called party/subscriber is determined to be within the area local to the home PBX and the calling party has dialed the called party/subscriber'"'"'s PRS telephone number, converting the PRS telephone number to a local extension number on the home PBX associated with the called party/subscriber and initiating connection of the call from the PBX to the local extension number; and

if the called party/subscriber is determined to be outside the area local to the home PBX and the calling party has dialed the called party/subscriber'"'"'s local extension number on the home PBX, converting the dialed local extension number to the called party/subscriber'"'"'s PRS number and initiating connection of the call from the PBX to the PRS number.

11. The method of claim 10 wherein the pager is a two-way pager and the step of determining whether the called party/subscriber is within an area local to the home PBX comprises the step of using two-way paging technology to determine whether the pager is within the area local to the home PBX.

12. The method of claim 10 further comprising the steps of:

if the called party/subscriber is determined to be within the area local to the home PBX and the calling party has dialed the called party/subscriber'"'"'s PRS number, upon initiating connection of the call from the PBX to the local extension number also locally paging the called party/subscriber within the area local to the home PBX to alert the called party/subscriber that a telephone call is waiting;

if the called party is responsive to the local page, receiving a return telephone call from the called party/subscriber at the home PBX; and

bridging together at the home PBX the telephone call from the calling party and the called party/subscriber'"'"'s return telephone call.

13. The method of claim 10 further comprising the steps of:

if the called party/subscriber is determined to be outside the area local to the home PBX and the calling party has dialed the called party/subscriber'"'"'s local extension number, completing connection of the call from the PBX to the called party/subscriber'"'"'s PRS number to the network platform of the personal reach system associated with the called party/subscriber; and

initiating a nationwide page to the called party/subscriber.

14. The method of claim 13 further comprising the steps of:

if the called party is responsive to the nationwide page, receiving a return telephone call from the called party/subscriber at the personal reach system network platform; and

bridging together the return call and the calling party'"'"'s call at the personal reach system network platform.
