System and method for generating charging data for short message delivery

摘要

A method encoded in a memory of a specialized network node configured for allowing an SMSC to be informed of the location of the UE originating a short message via an IP-SM-GW and also of the location of the receiving UE when a short message is delivered through an IP-SM-GW. Additionally the disclosed method ensures that charging systems can correlate IP-SM-GW charging requests for a short message with any charging requests generated by the SMSC for the same message.

1. A method encoded in a memory of a specialized network node configured for generating a charging record for delivering a Short Message Service (SMS) message over an Internet Protocol Multimedia Subsystem (IMS) network, comprising:
determining routing information for the SMS message; receiving the SMS message with a unique charging identifier assigned to the SMS message by an SMS Service Center (SMSC) network node; attempting to deliver the SMS message to a destination device; receiving an error message generated in response to a failure to deliver the SMS message to the destination device via IMS; forwarding the SMS message to at least one of a Circuit-Switched (CS) and Packet-Switched (PS) network nodes to deliver the SMS message to the destination device; forwarding an address of the at least one of CS and PS network nodes that successfully delivered the SMS message to the destination device to the SMSC network node in response to a successful delivery; and using the address of the at least one of CS and PS network nodes, correlating Internet Protocol Short Message Gateway (IP-SM-GW) charging records and SMSC charging records to determine costs of delivering the SMS message.
