Abstract

A system and method for the switches of a telecommunications network to generate call records for telephone calls using a flexible and expandable record format. Upon receipt of a telephone call, a switch in the network analyzes the telephone call to determine whether the default call record is sufficiently large to store call record information pertaining to the telephone call, or whether the expanded call record must be used to store the call information pertaining to the telephone call. After determining which call record to use, the switch generates the default or expanded call record. The switch sends a billing block, comprised of completed call records, to a billing center upon filling an entire billing block.

Claims

1. A method of generating a default call record or an expanded call record to store information about a telephone call from a calling location to a destination address, said method comprising the steps of:

(1) analyzing the telephone call to determine whether the default call record is sufficiently large to store call information pertaining to the telephone call, or whether the expanded call record must be used to store said call information pertaining to the telephone call;

(2) generating the default call record or the expanded call record for the telephone call as determined by step (1);

(3) recording timepoints in epoch time format in the default call record or the expanded call record as determined by step (1); and

(4) sending the default call record or the expanded call record, as determined by step (1), to a billing center upon termination of the telephone call.

2. A method according to claim 1, wherein step (1) comprises:

(1.a) determining the number of digits associated with the telephone call;

(1.b) determining if the telephone call required operator assistance; and

(1.c) determining if the telephone call invoked a special feature.

3. A method according to claim 2, wherein step (1.a) further comprises:

(1a.1) determining if the calling location contains more than ten digits;

(1.a.2) determining if the destination address contains more than seventeen digits; and

(1a.3) determining if more than twenty-two digits, including supplemental data, are required for an authorization code of the telephone call;

wherein if steps (1a.1), (1.a.2), and (1.a.3) are all false, said method generates a default call record, otherwise, said method generates an expanded call record.

4. A method according to claim 2, wherein step (1.c) further comprises:

(1.c.1) determining if the telephone call is a wideband call; and

(1.c.2) determining if the telephone call is an enhanced voice service/network audio response system telephone call;

wherein if steps (1.c.1), and (1.c.2) are all false, said method generates a default call record, otherwise, said method generates an expanded call record.

5. A method according to claim 2, wherein step (1.b) further comprises:

(1.b.1) determining if the telephone includes pre-translated digits and operator assistance;

(1.b.2) determining if the telephone call includes more than ten pretranslated digits and no operator assistance; and

(1.b.3) determining if the telephone call required an operator'"'"'s assistance for a time and charge feature;

wherein if steps (1.b.1), (1.b.2) and (1.b.3) are all false, said method generates a default call record, otherwise, said method generates an expanded call record.

6. A method according to claim 1, wherein the default call record is a Call Detail Record (CDR) and the expanded call record is an Expanded Call Detail Record (ECDR), if the telephone call is a typical telephone call that accesses a public telephone network and does not require operator assistance.

7. A method according to claim 1, wherein the default call record is a Private Network Record (PNR) and the expanded call record is an Expanded Private Network Record (EPNR), if the telephone call is a typical telephone call that accesses a private telephone network and does not require operator assistance.

8. A method according to claim 1, wherein the default call record is an Operator Service Record (OSR) and the expanded call record is an Expanded Operator Service Record (EOSR), if the telephone call accesses a public telephone network and requires operator assistance.

9. A method according to claim 1, wherein the default call record is a Private Operator Service Record (POSR) and the expanded call record is an Expanded Private Operator Service Record (EPOSR), if the telephone call accesses a private telephone network and requires operator assistance.

10. A communications switch for generating a default call record or an expanded call record to store information about a telephone call from a calling location to a destination address, said communications switch comprising:

analyzing means for analyzing the telephone call to determine whether the default call record is sufficiently large to store call information pertaining to the telephone call, or whether the expanded call record must be used to store said call information pertaining to the telephone call;

generating means for generating the default call record or the expanded call record for the telephone call as determined by said analyzing means;

recording means for recording timepoints in epoch time format in the default call record or the expanded call record; and

sending means for sending the default call record or the expanded call record to a billing center upon termination of the telephone call.

11. The communications switch according to claim 10, wherein said analyzing means comprises number determining means for determining the number of digits associated with the telephone call.

12. The communications switch according to claim 10, wherein said analyzing means comprises means for determining if the telephone call required operator assistance.

13. The communications switch according to claim 10, wherein said analyzing means comprises means for determining if the telephone call invoked a special feature.

14. The communications switch according to claim 11, wherein said number determining means comprises:

calling location means for determining if the calling location contains more than ten digits;

destination address means for determining if the destination address contains more than seventeen digits; and

authorization code means for determining if more than twenty-two digits, including supplemental data, are required for an authorization code of the telephone call;

wherein if said calling location means, destination address means, and authorization code means are all false, said communications switch generates a default call record, otherwise, said communications switch generates an expanded call record.
