Method for NPA split processing on a service control point
First Claim
1. A method for numbering plan area (NPA) split processing on a service control point, the method comprising:
- (a) providing first and second call processing records associated with a telephone number undergoing an NPA split, wherein the first call processing record is identified by a telephone number comprising an old NPA and wherein the second call processing record is identified by a telephone number comprising a new NPA;
(b) sending a query to a service control point during a permissive dialing period, wherein the query comprises the telephone number comprising the old NPA;
(c) determining whether the first call processing record identifies a service that is NPA sensitive; and
(d) if the first call processing record identifies a service that is NPA sensitive, using the second call processing record instead of the first call processing record.

Abstract
The preferred embodiments described herein provide a method for NPA split processing on a service control point. These preferred embodiments can be used to overcome problems encountered during a permissive dialing period of an NPA split and yield several advantages over prior art approaches to this problem. Specifically, these preferred embodiments do not require changes to be made to an existing call processing record to include a pointer to a new call processing record identified by a telephone number with a new NPA. Additionally, unlike prior approaches that require changes to be made to all incoming query messages to a service control point, these preferred embodiments do not require extra processing for services that are not NPA sensitive.

14. A method for numbering plan area (NPA) split processing on a service control point, the method comprising:
-
(a) providing a service control point comprising a first profile management call processing record associated with a service that is NPA sensitive and a second profile management call processing record associated with a service that is not NPA sensitive; (b) sending a query to the service control point during a permissive dialing period, wherein the query comprises a telephone number undergoing an NPA split; (c) in response to the query being sent to the service control point to change the first profile management call processing record; (c1) determining whether the query was sent during a permissive dialing period; and (c2) if the query was sent during the permissive dialing period, changing data in a subscriber'"'"'s call processing record identified by a telephone number with an old NPA; and (d) in response to the query sent to the service control point to change the second profile management call processing record, changing data in a subscriber'"'"'s call processing record identified by a telephone number with a new NPA. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for NPA numbering plan area (NPA) split processing on a service control point, the method comprising:
-
(a) providing first and second call processing records associated with a telephone number undergoing an NPA split, wherein the first call processing record is identified by a telephone number comprising an old NPA and wherein the second call processing record is identified by a telephone number comprising a new NPA; (b) receiving a query at a service control point during a permissive dialing period, wherein the query comprises one or more telephone numbers comprising an NPA undergoing an NPA split; (c) assigning the telephone numbers to call variables; (d) retrieving a call processing record identified by one of the call variables, wherein the call processing record identifies a subscriber and one or more services; (e) determining whether any of the subscribed services is NPA sensitive; (f) determining whether the permissive dialing period for that NPA is active; (g) if the service is NPA sensitive and the permissive dialing period is active, changing the NPA in the call variables to a new NPA; (h) retrieving a second call processing record identified by the call variable with the new NPA; and (i) using the second call processing record instead of the first-mentioned call processing record. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
