Methods, systems, and computer readable media for providing triggerless equipment identity register (EIR) service in a diameter network

A system for providing triggerless equipment identity register (EIR) service in a Diameter network that eliminates the need for a switching office trigger, the system comprising:

• a Diameter routing agent (DRA) including:
• a hardware message processor for intercepting a non-EIR message that is addressed to a home subscriber server (HSS), the non-EIR message comprising a Diameter Update Location Request (ULR) message or a Diameter Authentication Information Request (AIR) message;
• and
• a triggerless EIR module for performing an EIR lookup in an EIR database in response to intercepting the non-EIR message, wherein the triggerless EIR module receives an indication that access to the network is either allowed or denied and, in response to receiving an indication that access to the network is allowed, the EIR module relays the non-EIR message to the HSS that the non-EIR message is addressed to, and in response to receiving an indication that access to the network is denied, the EIR module formulates an Update Location Answer (ULA) message or an Authentication Information Answer (AIA) message and responds to the non-EIR message on behalf of the HSS without forwarding the non-EIR message to the HSS.

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

• at a Diameter routing agent (DRA):
• intercepting, at the DRA, a non-EIR message that is addressed to a home subscriber server (HSS), the non-EIR message comprising a Diameter update location request (ULR) message or a Diameter authentication information request (AIR) message;
• performing, by the DRA, an EIR lookup in an EIR database in response to intercepting the non-EIR message;
• receiving, at the DRA, an indication that access to the network is either allowed or denied;
• in response to receiving an indication that access to the network is allowed, relaying the non-EIR message to the HSS that the non-EIR message is addressed to;
• and
• in response to receiving an indication that access to the network is denied, formulating an Update Location Answer (ULA) message or an Authentication Information Answer (AIA) message and responding on behalf of the HSS without forwarding the non-EIR message to the HSS.
