Methods, systems, and computer readable media for provisioning a diameter binding repository

A system for provisioning a Diameter binding repository, the system comprising:

• a Diameter binding repository (DBR) configured to store Diameter binding records for binding Diameter signaling message information to Diameter transactions;
• and
• a Diameter signaling router (DSR) configured to receive a Diameter signaling message that is associated with a mobile subscriber and includes mobile subscriber related information, to select a network service node from a plurality of network service nodes configured to process the Diameter signaling message, to query a subscriber data management (SDM) node using the mobile subscriber related information that includes an international mobile subscriber identity (IMSI) to obtain additional information associated with the mobile subscriber, to receive a response including the additional information that comprises at least a Diameter session identifier from the SDM node, to generate Diameter binding record information using the mobile subscriber related information, the additional information, and an identifier corresponding to the selected network service node, wherein the Diameter binding record information associates the selected network service node with both the IMSI and the Diameter session identifier, and to send a provisioning message to the DBR that includes the Diameter binding record information to be stored in the DBR, wherein the DBR is configured to store the Diameter binding repository information in a Diameter binding record and is configured to be provisioned by one or more network elements that are separate from the DSR;
• wherein the Diameter binding record information is used to update the existing Diameter binding record in a manner in which mobile subscriber related identifiers listed in the existing Diameter binding record are associated with both the IMSI and the additional information that includes at least the Diameter session identifier.

A non-transitory computer readable medium comprising computer executable instructions embodied in a computer readable medium that when executed by a processor of a computer control the computer to perform steps comprising:

• receiving, at a DSR, a Diameter signaling message that is associated with a mobile subscriber and includes mobile subscriber related information;
• selecting, by the DSR, a network service node from a plurality of network service nodes configured to process the Diameter signaling message;
• querying, by the DSR, a subscriber data management (SDM) node using the mobile subscriber related information to obtain additional information associated with the mobile subscriber, wherein querying the SDM node includes querying the SDM node using an international mobile subscriber identity (IMSI);
• receiving, by the DSR, a response including the additional information that comprises at least a Diameter session identifier from the SDM node;
• generating, by the DSR, Diameter binding record information using the mobile subscriber related information, the additional information, and an identifier corresponding to the selected network service node, wherein the Diameter binding record information associates the selected network service node with both the IMSI and the Diameter session identifier;
• and
• sending, by the DSR to a Diameter binding repository (DBR), a provisioning message that includes the Diameter binding record information for storage in the DBR, wherein the DBR is configured to be provisioned by one or more network elements that are separate from the DSR, and wherein the Diameter binding record information is used to update the existing Diameter binding record in a manner in which mobile subscriber related identifiers listed in the existing Diameter binding record are associated with both the IMSI and the additional information that includes at least the Diameter session identifier.
