Functions and Method for Handling a Credit Pool of Service Units

A method performed by a Control Plane (CP) function for handling a credit pool comprising granted service units to be used by multiple services, wherein the multiple services are grouped in at least one first Rating Group (RG), the method comprising:

• creating an individual Usage Reporting Rule (URR) for each of the at least one first RG, wherein each individual URR comprises a first credit pool threshold;
• providing the individual URRs to a User Plane (UP) function;
• creating a Usage Reporting Rule for the Credit Pool (URR CRPL), wherein the URR CRPL comprises instructions to the UP function to aggregate service unit usage for all individual URRs for all first RGs, and wherein the URR CRPL further comprises the first credit pool threshold;
• and
• providing the URR CRPL to the UP function.

A method performed by a User Plane (UP) function for handling a credit pool comprising granted service units to be used by multiple services, wherein the multiple services are grouped in at least one first Rating Group (RG), the method comprising:

• obtaining, from a Control Plane (CP) function, an individual Usage Reporting Rule (URR) for each of the at least one first RGs, wherein each individual URR comprises a first credit pool threshold;
• obtaining a Usage Reporting Rule for the Credit Pool (URR CRPL) from the CP function, wherein the URR CRPL comprises instructions to aggregate service unit usage for all individual URRs for all first RGs, and wherein the URR CRPL further comprises the first credit pool threshold;
• counting the used service units for each individual URRs for the first RGs;
• and
• aggregating the counted service unit usage for all individual URRs for all first RGs.

A Control Plane (CP) function for handling a credit pool comprising granted service units to be used by multiple services, wherein the multiple services are grouped in at least one first Rating Group (RG), the CP function comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the CP function is operative to:
• create an individual Usage Reporting Rule (URR) for each of the at least one first RG, wherein each individual URR comprises a first credit pool threshold;
• provide the individual URRs to a User Plane (UP) function;
• create a Usage Reporting Rule for the Credit Pool (URR CRPL) wherein the URR CRPL comprises instructions to the UP function to aggregate service unit usage for all individual URRs for all first RGs, and wherein the URR CRPL further comprises the first credit pool threshold;
• and to
• provide the URR CRPL to the UP function.

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the UP function is operative to:
• obtain, from a Control Plane (CP) function, an individual Usage Reporting Rule (URR) for each of the at least one first RGs, wherein each individual URR comprises a first credit pool threshold;
• obtain a Usage Reporting Rule for the Credit Pool (URR CRPL) from the CP function, wherein the URR CRPL comprises instructions to aggregate service unit usage for all individual URRs for all first RGs, and wherein the URR CRPL further comprises the first credit pool threshold;
• count the used service units for each individual URRs for the first RGs;
• and to
• aggregate the counted service unit usage for all individual URRs for all first RGs.
