MESSAGE ROUTING

In a message routing method an application or device sends a message in a mobile network, the message having a status report request. The message is delivered via network elements including a router, and the router routs a status report to the originating device or application which cannot accept it. The router communicates with a message service centre having store-and-forward capability, and the message service centre performs a re-try of sending the status report to the originating device or application. The status report may be embedded in an otherwise conventional message to the service centre, which may for example be an SMSC. The status report may be embedded in a conventional SMC-MO PDU, without affecting the GSM or other network protocol.
