Abstract: An M2M service provider (41) is a provider of a plurality of services (31-33). A method of processing charging information for machine-to-machine (M2M) communication between at least one M2M device (10) and an M2M service provider (41) comprises creating (102) a charging record (90) for recording usage information of the plurality of services (31-33) of the service provider (41). For each of the plurality of services (31-33) of the service provider (41), per-service usage information (94) is accumulated (105). Usage of the service by the at least one M2M device (10) is aggregated. The per-service usage information (94) is stored (108) in the charging record (90). The charging record can include at least one volume-based limit or time-based limit for publishing the charging record.
