Abstract: A system and method for numbering plan area (NPA) split processing is disclosed. In one implementation, a query is received during a permissive dialing period. The query comprises a destination location that is associated with a first NPA. It is determined whether a first call processing record identifies a service that is NPA sensitive. The first call processing record is associated with a destination location that is undergoing a NPA split. The first call processing record is identified by the destination location and the destination location is associated with a first NPA. A second call processing record is then used for processing in place of the first call processing record when the first call processing record identifies a service that is NPA sensitive. The second call processing record is associated with the destination location that is undergoing an NPA split. The second call processing record is identified by the destination location and the destination location is associated with a second NPA.

Abstract: A system and method deliver audible caller identification information when standard Caller ID information is invalid or can not be provided. In one disclosed embodiment, the Caller ID information must include a valid number of digits and a valid area code. If the Caller ID information is not valid, a calling party is prompted by an announcement to provide the audible caller identification information.

Abstract: A subscriber is provided with personal caller identification information when a telephone call is placed to the subscriber. In particular, a network service platform is supplied with a calling party number. A network caller ID database is queried using the calling party number to retrieve network caller ID information. A central personal address book is queried, using the calling party number, to retrieve personal caller identification information associated with the calling party number. Then the network element forwards the network caller identification information supplemented with the personal caller identification information to the subscriber when connecting the telephone call to the subscriber.

Abstract: A current time and a current Gregorian date are converted into an epoch time stamp. A number of seconds that have elapsed since a predetermined date up until the current year is determined. A number of seconds that have elapsed since the beginning of the current year up until the current month is determined based on whether the current year is a leap year. In addition, a number of seconds that have elapsed since the beginning of the current month up until the current day is calculated, as is a number of seconds that have elapsed during the current day. All of these values are summed to obtain a converted time. Finally, it is determined whether Daylight Savings Time is in effect, and when Daylight Savings Time is not in effect, 3600 seconds are added to the converted time.
