A method, a corresponding apparatus, and a computer program product for dynamic charging over multiple network nodes. The method comprises collecting, at a first network node which has a first connection with a user equipment, charging information with respect to a second connection established between the user equipment and a second network node, wherein the second network node is connected with the first network node. The method also comprises combining charging information with respect to the first connection and the charging information with respect to the second connection. The method additionally comprises sending the combined charging information from the first network node to a core network entity for charging the user equipment. With the claimed inventions, the core network and wireless operators could be able to bill the services based on specific offloaded bearers considering associated QoS information, regarding to the case of multi-PLMN scenarios under network sharing.
