Service Domain Charging Systems and Methods

In a service layer of a Machine-to-Machine (M2M) network, a method comprising:

• receiving a policy at a service domain charging management function, the policy being defined as a rule with associated attributes;
• and
• using the policy to determine chargeable events within the service layer of the M2M network.

In a service layer of an Machine-to-Machine (M2M) network, a method comprising:

• receiving at a service domain charging management function at an infrastructure node charging policies for the service domain;
• and
• distributing the policies from the service domain charging management function at the infrastructure node to a service domain charging management function at an end node.

In a service layer that interacts with a 3GPP network, a method comprising:

• transferring charging information between a service domain charging system in the service layer and a Machine-Type Communications Interworking Function (MTC-IWF) in the 3GPP network across a Tsp reference point, and
• in the service domain charging system in the service layer or the MTC-IWF in the 3GPP network, using the transferred charging information.

In a service layer of an Machine-to-Machine (M2M) network, a method comprising:

• receiving at a service domain charging management function at a node charging policies for the service domain from an application;
• and
• distributing the policies from the service domain charging management function at the node to a service domain charging management function at another node.
