Systems, methods, and computer readable media for using a signaling message routing node to provide backup subscriber information management service

A system for using a signaling message routing node to provide backup mobility management service, the system comprising:

• a signaling message routing node, the signaling message routing node including:
• a communications module for receiving a first mobility management message having a message destination and being associated with a subscriber;
• and
• a subscriber information management module for obtaining information associated with the subscriber, for determining whether the message destination is operable to process the first subscriber information management message, for, in response to determining that the message destination is operable to process the first subscriber information management message, routing the first subscriber information management message to the message destination, and, in response to determining that the message destination is not operable to process the first subscriber information management message, responding to the first subscriber information management message on behalf of the message destination.

A computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

• obtaining, by a signaling message routing node, information associated with a subscriber;
• receiving, at the signaling message routing node, a first subscriber information management message including a message destination and being associated with the subscriber;
• determining whether the message destination is operable to process the first subscriber information management message;
• in response to determining that the message destination is operable to process the first subscriber information management message, routing the first subscriber information message to the message destination;
• and
• in response to determining that the message destination is not operable to process the first subscriber information management message, responding to the first subscriber information management message on behalf of the message destination.
