Methods, systems, and computer readable media for short message delivery status report validation

A method for validating a short message delivery status report, the method comprising:

• at a first network node:
• receiving the short message delivery status report appearing to be associated with a short message delivery to a mobile subscriber;
• determining, using a data store containing information about short message delivery attempts, whether the short message delivery status report is valid or invalid, wherein the information about the short message delivery attempts indicates a validation time period for receiving a valid short message delivery status report;
• and
• performing a processing action based on the determination, wherein determining that the short message delivery status report is valid includes obtaining, using a subscriber identifier in the short message delivery status report, a data entry of the data store that corresponds to the mobile subscriber and determining that a network node identifier indicating a sender of the short message delivery status report matches information in the data entry of the data store that corresponds to the mobile subscriber.

A system for validating a short message delivery status report, the system comprising:

• a first network node comprising:
• at least one processor;
• and
• a memory,
• wherein the first network node is configured for, prior to receiving the short message delivery status report:
• receiving a send routing information for short message response message containing a subscriber identifier indicating a mobile subscriber and a network node identifier indicating a current location of the mobile subscriber;
• storing a network node identifier in a data entry of a data store that corresponds to the mobile subscriber indicated by the subscriber identifier;
• forwarding the send routing information for short message response message to a requester;
• receiving and forwarding a forward short message request message associated with the mobile subscriber;
• and
• storing timing information associated with the forward short message request message in the data entry of the data store that corresponds to the mobile subscriber and wherein the first network node is further configured for:
• receiving the short message delivery status report appearing to be associated with a short message delivery to the mobile subscriber;
• determining, using the data store containing information about short message delivery attempts, whether the short message delivery status report is valid or invalid, wherein the information about the short message delivery attempts indicates a validation time period for receiving a valid short message delivery status report;
• and
• performing a processing action based on the determination.

A non-transitory computer readable medium comprising computer executable instructions embodied in the non-transitory computer readable medium that when executed by at least one processor of at least one computer cause the at least one computer to perform steps comprising:

• at a first network node and prior to receiving a short message delivery status report:
• receiving a send routing information for short message response message containing a subscriber identifier indicating a mobile subscriber and a network node identifier indicating a current location of the mobile subscriber;
• storing a network node identifier in a data entry of a data store that corresponds to the mobile subscriber indicated by the subscriber identifier;
• forwarding the send routing information for short message response message to a requester;
• receiving and forwarding a forward short message request message associated with the mobile subscriber;
• and
• storing timing information associated with the forward short message request message in the data entry of the data store that corresponds to the mobile subscriber;
• and further comprising, at the first network node:
• receiving the short message delivery status report appearing to be associated with a short message delivery to the mobile subscriber;
• determining, using the data store containing information about short message delivery attempts, whether the short message delivery status report is valid or invalid, wherein the information about the short message delivery attempts indicates a validation time period for receiving a valid short message delivery status report;
• and
• performing a processing action based on the determination.
