Abstract
A communication system comprises network elements (103, 105, 107, 109) and user equipments (101), at least some of which comprise a charging proxy (205). The system further comprises a charging server (111) which includes a topic controller (305) for initializing charging topics where each charging topic is associable with charging data. The charging server (111) furthermore comprises functionality for registering proxies as subscribing proxies or publishing proxies (or both) for the different charging topics. A receiver (301, 311) receives charging data messages from charging proxies and validates a first set of charging data belonging to a first charging topic in response to a first set of charging proxies registered as publishing proxies for the first charging topic. A charging data transmitter (313) transmits the first set of charging data to a second set of charging proxies registered as subscribing proxies for the first charging topic.
