CDR filtering for virtual operators
View Patent ↗Systems and methods that filter Charging Data Records (CDRs) before sending the CDRs to a virtual operator, such as a Network Unaffiliated Virtual Operator (NUVO). In one embodiment, a communication network provides services to subscribers of a virtual operator. The communication network includes a reporting entity comprising a CDR database configured to store CDRs for subscribers of the virtual operator. The reporting entity also includes a filtering node configured to filter the CDRs to remove fields that are not authorized to be shared with the virtual operator, and to report the filtered CDRs to the virtual operator.
1. An apparatus comprising:
a reporting entity of a communication network that provides services to subscribers of a virtual operator, the reporting entity comprising:
a Charging Data Record (CDR) database configured to store CDRs for the subscribers of the virtual operator;
a permissions database configured to store a plurality of data entries, where each of the data entries includes a permission level, and a template indicating CDR fields that are authorized to be shared at the permission level; and
a filtering node including a hardware processor configured to query the permissions database to retrieve one of the templates corresponding with the permission level of the virtual operator, to filter the CDRs based on the template to remove fields that are not authorized to be shared with the virtual operator, and to report the filtered CDRs to the virtual operator.
2. The apparatus of claim 1 wherein:
the permissions database is configured to store, in each of the data entries, an indicator of CDR types that are authorized to be shared.
3. The apparatus of claim 2 wherein:
the filtering node is configured to filter the CDRs to remove the CDR types that are not authorized to be shared with the virtual operator.
4. The apparatus of claim 1 wherein:
the filtering node is configured to push the filtered CDRs to the virtual operator at the end of a billing cycle.
5. The apparatus of claim 1 wherein:
the filtering node is configured to receive a fetch request from the virtual operator, and to report the filtered CDRs to the virtual operator in response to the fetch request.
6. The apparatus of claim 1 wherein:
the virtual operator comprises a Network Unaffiliated Virtual Operator (NUVO).
7. A method comprising:
storing Charging Data Records (CDRs) for services provided through a communication network to subscribers of a virtual operator;
storing a plurality of data entries, where each of the data entries includes a permission level, and a template indicating CDR fields that are authorized to be shared at the permission level;
retrieving one of the templates corresponding with the permission level of the virtual operator;
filtering the CDRs based on the template to remove fields that are not authorized to be shared with the virtual operator; and
reporting the filtered CDRs to the virtual operator.
8. The method of claim 7 further comprising:
storing, in each of the data entries, an indicator of CDR types that are authorized to be shared.
9. The method of claim 8 further comprising:
filtering the CDRs to remove the CDR types that are not authorized to be shared with the virtual operator.
10. The apparatus of claim 7 wherein:
the virtual operator comprises a Network Unaffiliated Virtual Operator (NUVO).
11. A non-transitory computer readable medium that stores program instructions for a reporting entity of a communication network that provides services to subscribers of a virtual operator, where the program instructions when executed by a computer system, instruct the computer system to:
store Charging Data Records (CDRs) for the subscribers of the virtual operator;
store a plurality of data entries, where each of the data entries includes a permission level, and a template indicating CDR fields that are authorized to be shared at the permission level;
retrieve one of the templates corresponding with the permission level of the virtual operator;
filter the CDRs based on the template to remove fields that are not authorized to be shared with the virtual operator; and
report the filtered CDRs to the virtual operator.
12. The computer readable medium of claim 11 wherein the program instructions instruct the computer system to:
store, in each of the data entries, an indicator of CDR types that are authorized to be shared.
13. The computer readable medium of claim 12 wherein the program instructions instruct the computer system to:
filter the CDRs to remove the CDR types that are not authorized to be shared with the virtual operator.
14. The computer readable medium of claim 11 wherein:
the virtual operator comprises a Network Unaffiliated Virtual Operator (NUVO).
