Abstract
Existing switch markings for telephone numbers are mechanically manipulated via the Recent Change channel to provide an appropriate treatment. In case a call to a vacant pooled-in number cannot be completed, a terminating switch, instead of generating a REL message with a Cause Code 26 and tearing down the call, connects the call to an Operations Support System that provides a predetermined announcement to a calling party. Calls directed toward numbers that are ported-out are placed on a Machine Intercept, which results in sending a cause code 26 to an originating switch.
Claims13
In a telecommunication system incorporating telephone number pooling, a method of providing intercept treatment to a call directed toward a vacant pooled Telephone Number (TN), the method comprising the steps of:
- determining that the TN is a part of a block of pooled-in TNs;
- determining whether the TN is a part of a clean or a contaminated thousands block of numbers;
- if the block of pooled-in numbers is clean, transmitting at least one Recent Change message to a switching system supporting the block of pooled-in numbers, said Recent Change message specifying Operator Intercept treatment to a call made to a vacant TN in the block whereby Cause Code 26 treatment is suppressed.
In a telecommunication system incorporating telephone number pooling, a method of providing intercept treatment to a call directed toward a vacant pooled Telephone Number (TN), the method comprising the steps of:
- determining that the TN is a “pooled-in” TN of a clean thousands block of numbers;
- determining that the TN is vacant;
- and
- transmitting a Recent Change message to a switching system supporting the TN, said Recent Change message specifying Operator Intercept treatment to a call made to the TN whereby Cause Code 26 treatment is suppressed.
