Mobile Switching Center SMS-C Address Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, short messages cannot be delivered successfully if the SMS-C address is incorrectly configured in the mobile station, as existing methods fail to correct or bypass the incorrect address.
Innovation Solution
A method that corrects the SMS-C address using a stored address list in the mobile switching center (MSC) before forwarding the message, or after it has been rejected by the SMS-C, ensuring delivery with a preset default address.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the SMS-C address is configured in the mobile station, then the short message can be routed to the SMS service center, but if the address is incorrect the message delivery fails
Solution Approach 1:
The mobile switching center acts as an intermediary between the mobile station and the SMS service center. It receives the short message with the potentially incorrect SMS-C address, validates the address using a stored list of valid addresses, and either corrects the address or forwards the message using a default address, thereby mediating the communication failure caused by address configuration errors
Solution Approach 2:
The mobile switching center performs preliminary address validation and correction before forwarding the short message to the SMS service center. By checking the SMS-C address against a pre-stored list of valid addresses and correcting it in advance, the system prevents delivery failures that would occur if the incorrect address reached the SMS service center
2Reliability
If the SMS-C address is corrected in the mobile switching center, then message delivery succeeds, but the system complexity increases
Solution Approach 1:
The mobile switching center performs multiple functions: it acts as a standard message routing switch, maintains a list of valid SMS-C addresses, validates incoming message addresses, corrects incorrect addresses, and provides default routing. By consolidating these diverse functions into a single existing network element, the system achieves reliable message delivery without adding separate complex validation infrastructure

AI summary
The invention relates to a method for delivering a short message in a mobile communications system, in which the short message sent from a mobile station is received by an SMS-Service-Centre, SMS-C, and forwarded to a corresponding recipient, wherein the SMS-C is addressed by means of an SMS-C address in the mobile communications system. The invention is distinguished by the fact that an SMS-C address recognized as erroneous is corrected on the part of the mobile communications system, and the delivery of the short message is continued with the corrected SMS-C address.
