Abstract

A method and apparatus that allows different likelihoods of call completion during very heavy call loading conditions to be supplied to different customers. Customers are assigned to different levels of service and these levels of service are used to manage call completion in throughout the telecommunication network during very heavy call loading periods. Thus, a securities broker may have a higher likelihood of completing a call near the close of a trading session than the average telephone customer. However, each caller may be offered an opportunity to immediately increase his or her level of service and thus likelihood of completing a call to the highest available level if a call is not completed at the caller'"'"'s lower level of service.

Claims

1. In a telecommunication system, an apparatus for selectively controlling a telephone call, comprising:

means for determining if a call gapping control is active for the present telephone call;

means responsive to said determining means for obtaining level of service information which is associated with an ANI of the present telephone call if said call gapping control is active; and

means for applying said call gapping control to either allow the telephone call to be completed or terminate the telephone call based on the level of service if said call gapping control is active for the present telephone call;

wherein the probability of completing the call while said call gapping control is active increases as the level of service of the call increases.

2. The apparatus as set forth in claim 1, further comprising means for completing the telephone call if said call gapping control is not active.

3. An apparatus as set forth in claim 1, further comprising:

means for completing the telephone call if the call is allowed to be completed;

means for announcing to the caller that the telephone call will not be completed; and

means for terminating the telephone call if the call is to be terminated.

4. A method for call gapping a telephone call comprising the steps of:

a. collecting called number;

b. determining if call gapping is active for the telephone call and if call gapping for the telephone call is not active proceeding to step r, while if call gapping is active for the telephone call proceeding to step c;

m. assigning a default network management LOS to this call and proceed to step o;

n. retrieving NM LOS from originating NM LOS table for this ANI or calling number;

o. determining if call gapping is active and if call gapping is not active proceeding to step r and if call gapping is active proceeding to step p;

p. applying a level of call gapping based upon called number and NM LOS and determining if this call is allowed to be completed;

q. if the call is not allowed to be completed, routing call to an announcement; and

r. if the call is allowed to be completed, routing call to its destination.

5. The method as set forth in claim 4, wherein the rate of call gapping is different for different levels of service.

6. The method as set forth in claim 4, wherein the rate of call gapping is different for different calling numbers.

7. The method as set forth in claim 4, wherein the rate of call gapping is different, based upon a portion of each calling number.

8. The method as set forth in claim 4, wherein said announcement of step r further comprises the steps of:

s. if a higher level of service is available to the calling party which has a greater chance of completing the call, announcing to the originator that the circuits are busy for the call'"'"'s present NM LOS and offering to increase the call'"'"'s NM LOS and thereby the chances of completing the call for an extra fee if the calling party accepts by pressing a specific key of a keypad of the originating telephone station; and

t. if the calling party accepts the offer to an increase in NM LOS, increasing the NM LOS for the call and returning to step p and if the call is completed with the increased NM LOS charging the extra fee to the originating party'"'"'s account.

9. A method for using a trunk group control to manage a telephone call comprising the steps of:

a. collecting a called number of this call;

b. determining a trunk group for communicating this call;

c. determining if a trunk group control is active for a trunk group communicating the telephone call and if a trunk group control is not active proceeding to step n, while if a trunk group control is active proceeding to step d;

d. determining if ANI is available for this call and if ANI is not available proceeding to step e and if ANI is available proceeding to step f;

e. determining if calling number is available and if it is not available proceeding to step m, while if it is available proceeding to step f;

f. obtaining NM LOS for this call;

g. determining from ANI or calling number if this telephone call matches a number code and if there is a not a match proceeding to step m, while if there is a match proceeding to step h;

h. determining if query of an SCP database is required to obtain NM LOS and if a query is required proceeding to step i, while if a query is not required proceeding to step 1;

i. querying SCP database with either ANI or calling number to obtain NM LOS;

j. determining if the query is successful in finding a match in the SCP database and if a match is found obtaining the NM LOS from the SCP database and proceeding to step m, while if a match is not found proceeding to step k;
