at the mobile core network:

obtaining the one or more rules from one or more entities associated with the one or more billing systems, wherein the one or more rules are generated by the one or more entities associated with the one or more billing systems.

7. The method of claim 1 , further comprising:

at the mobile core network:

providing the one or more rules to control whether or when the one or more charging data records associated with the user equipment are to be aggregated before being provided to the one or more billing systems.

8. The method of claim 1 , further comprising:

at the mobile core network:

providing the one or more rules to control whether or when the one or more charging data records associated with the user equipment are to be split before being provided to a first billing system of the one or more billing systems and a second billing system of the one or more billing systems.

9. The method of claim 1 , wherein:

obtaining the request for the one or more rules includes obtaining the request for the one or more rules from a charging function or a charging gateway function; and

providing the one or more rules includes providing the one or more rules includes to the charging function or the charging gateway function.

10. The method of claim 1 , wherein the obtaining, the identifying, and the providing are performed by a charging filtering function.

11. An apparatus comprising:

a network interface configured to obtain or provide network communications in a mobile core network; and

one or more processors coupled to the network interface, wherein the one or more processors are configured to:

obtain a request for one or more rules that control whether or when one or more charging data records associated with a user equipment are to be provided to one or more billing systems, wherein the request includes an identification of the user equipment;

based on the identification of the user equipment, identify the one or more rules; and

provide the one or more rules to control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems.

12. The apparatus of claim 11 , wherein the one or more processors are configured to:

obtain a request for one or more rules that control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems based on an amount of information to be carried in the one or more charging data records.

13. The apparatus of claim 11 , wherein the one or more processors are configured to:

obtain a request for one or more rules that control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems based on a frequency at which the one or more charging data records are to be provided to the one or more billing systems.

14. The apparatus of claim 13 , wherein the one or more processors are configured to:

determine that a first rule controls whether or when the one or more charging data records associated with the user equipment are to be provided to a first billing system of the one or more billing systems based on a first frequency at which the one or more charging data records are to be provided to the first billing system;

determine that a second rule controls whether or when the one or more charging data records associated with the user equipment are to be provided to a second billing system of the one or more billing systems based on a second frequency at which the one or more charging data records are to be provided to the second billing system, wherein the second frequency is a multiple of the first frequency; and

provide one or more rules that control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems based on the first frequency.

15. The apparatus of claim 11 , wherein the one or more processors are configured to:

obtain a request for one or more rules that control whether or when the one or more charging data records associated with the user equipment are to be provided to the one or more billing systems based on a location of the user equipment.

16. The apparatus of claim 11 , wherein the one or more processors are configured to:

obtain the one or more rules from one or more entities associated with the one or more billing systems, wherein the one or more rules are generated by the one or more entities associated with the one or more billing systems.

17. One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor in a mobile core network, cause the processor to:
