A messaging system comprises SMS router (A) and SMSC (B) nodes for routing of messages. The nodes have overlapping responsibilities for message transfer, and hand over coordination information elements to each other and automatically process the elements to perform message operations in a co-ordinated manner. The information elements may include a correlation identifier which uniquely identifies a message which is intended to be passed on to another node. Other examples are a time of a last delivery attempt, a number of charging units, validation status, delivery error data, prepaid transaction identifiers, or keys that correlate charging records of multiple nodes. |
