Abstract

A system for providing personal communication services (PCS) is described, wherein a subscriber can tailor the telephone service to provide communication mobility and incoming call management. Calls to a personal number assigned to the subscriber are routed to a PCS service node which will re-route the call according to the subscriber'"'"'s service profile stored in a database. The service node insures that attempts to communicate with the subscriber are handled with appropriate consideration for who is calling, when the call is made, and the urgency of the call. In addition, the subscriber is given control over how the system will work for them in routing incoming calls.

Claims

1. A communication system for routing a call to a subscriber of a telephone mobility management service, wherein the subscriber of the service is assigned a unique personal telephone number, such that an incoming call made to the subscriber'"'"'s unique telephone number is routed to the subscriber according to a call routing schedule tailored by the subscriber, comprising:

a) database means for storing;

i) a list of network addresses associated with telephone devices for use by the service subscriber;

ii) a list of calling line identification numbers (CLIDs) of callers identified by the subscriber as requiring special routing treatment; and

iii) a subscriber schedule indicative of which one of said telephone devices an incoming call should be routed to, on the time and day the incoming call is received;

b) signalling receiver means for detecting the CLID of a caller when a call is received at said subscriber'"'"'s unique telephone number;

c) data processing means for receiving the detected CLID and for accessing said list of CLIDs of callers, said list of network addresses and said subscriber schedule stored in said database means; and

d) application server means for routing the call according to the special routing treatment associated with the caller'"'"'s CLID and subscriber schedule and wherein said subscriber can access said database means via said application server means and said data processor means to modify each list stored therein.

2. A communication system as defined in claim 1, wherein a call is routed by said application server means to a second telephone device provided in the subscriber schedule, if the subscriber cannot be reached at a first selected telephone device.

3. A communication system as defined in claim 2, wherein said list of network addresses associated with telephone devices for use by the service subscriber further provides the number of times a telephone device is to ring before said call is routed to said second telephone device.

4. A communication system as defined in claim 1, wherein the special routing treatment is stored with said list of CLIDs.

5. A communication system as defined in claim 4, wherein the special routing treatment is provided to incoming calls according to the area code contained with the CLID.

6. A method of routing a call to a subscriber of a telephone mobility management service, wherein the subscriber of the service is assigned a unique personal telephone number, such that an incoming call made to the subscriber'"'"'s unique telephone number is routed to the subscriber according to a call routing schedule tailored by the subscriber, comprising the steps of:

a) storing in database means;

i) a list of network addresses associated with telephone devices for use by the service subscriber;

ii) a list of Calling Line Identification numbers (CLIDs) of callers identified by the subscriber as requiring special routing treatment; and

iii) a subscriber schedule indicative of which one of said telephone devices an incoming call should be routed to, on the time and day the incoming call is received;

b) accessing, when an incoming call is received, said list of CLIDs to determine whether the incoming call requires a special routing treatment;

c) routing the incoming call, according to said special routing treatment and said subscriber schedule if a CLID is detected and contained on said list of CLIDs; and

d) if a CLID is not detected, routing the incoming call according to said special routing treatment in response to predetermined DTMF tones.

7. A method as defined in claim 6, wherein the special routing treatment is provided to incoming calls according to the area code contained with the CLID.

8. A method as defined in claim 6, wherein the incoming call is routed to a second telephone device provided in the subscriber schedule if the subscriber cannot be reached at a first telephone device.

9. A method as defined in claim 8, wherein said list of network addresses associated with telephone devices for use by the service subscriber further provides the number of times a telephone device is to ring before said call is routed to said second telephone device.

10. A method as defined in claim 6, wherein if an incoming call is routed to a telephone device which is shared between said service subscriber and another answering party, a prerecorded message will be sent to said shared telephone device such that the answering party is informed that the incoming call is directed to the service subscriber.

11. A method as defined in claim 10, wherein the subscriber can acknowledge his presence upon answering the incoming call on the shared telephone device, by dialling a predetermined DTMF code.
