The subject matter described herein includes methods, systems, and computer readable media for providing triggerless EIR service in a Diameter network. One method includes steps performed at a Diameter routing agent (DRA). The steps include, receiving a registration or authentication information request at the DRA. The steps further include performing, by the DRA, an EIR lookup in response to the registration or authentication information request message. The method further includes, relaying the registration or authentication information request message to a home subscriber server (HSS) or a home location register (HLR) or responding on behalf of the HSS or HLR based on results of the EIR lookup.

1. A method for providing triggerless equipment identity register (EIR) service in a Diameter network that eliminates the need for a switching office trigger, the method comprising: at a Diameter routing agent (DRA) comprising a hardware processor and memory for: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; andin 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. 2. The method of claim 1 wherein the non-EIR message includes an international mobile equipment identifier (IMEI) and wherein the DRA performs the EIR lookup using the IMEI. 3. The method of claim 1 wherein the DRA performs the EIR lookup using the IMEI and an international mobile station identifier (IMSI). 4. The method of claim 1 wherein the EIR message does not include an international mobile equipment identifier (IMEI) and wherein the DRA maps an international mobile subscriber identity (IMSI) in the registration or authentication information request message to an IMEI. 5. The method of claim 1 wherein the EIR database is internal to the DRA. 6. The method of claim 1 wherein the EIR database is external to the DRA. 7. The method of claim 6 wherein the DRA sends a query to the EIR database via an S13 or S13′ interface. 8. The method of claim 6 wherein the DRA sends a query to the EIR database via an SS7 Gf, MAP/F or other interface. 9. The method of claim 1 wherein the non-EIR message is generated at a mobility management entity (MME) or a serving GPRS support node (SGSN). 10. The method of claim 1 wherein, responding on behalf of the HSS comprises transmitting the ULA message or the AIA message to a mobility management entity (MME) or an serving GPRS support node (SGSN). 11. The method of claim 1 wherein responding on behalf of the HSS includes sending a response to the non-EIR message indicating that access to the network is denied. 12. 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; anda 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. 13. The system of claim 12 wherein the non-EIR message includes an international mobile equipment identifier (IMEI) and wherein the triggerless EIR module performs the EIR lookup using the IMEI. 14. The system of claim 13 wherein the DRA performs the EIR lookup using the IMEI and an international mobile station identifier (IMSI). 15. The system of claim 12 wherein the non-EIR message does not include an international mobile equipment identifier (IMEI) and wherein the triggerless EIR module maps an international mobile subscriber identity (IMSI) in the registration or authentication information request message to an IMEI. 16. The system of claim 12 wherein the DRA includes an internal EIR database and wherein the EIR lookup is performed in the internal EIR database. 17. The system of claim 16 wherein the internal EIR database is configured to store device access information for long term evolution (LTE) devices. 18. The system of claim 12 wherein the EIR database is external to the DRA. 19. The system of claim 12 wherein the DRA sends a query to the EIR database via an S13 or S13′ interface. 20. The system of claim 12 wherein the DRA sends a query to the EIR database via an SS7 Gf, MAP/F or other interface. 21. The system of claim 12 wherein the non-EIR message is generated at a mobility management entity (MME) or a serving GPRS support node (SGSN). 22. The system of claim 12 wherein responding on behalf of the HSS comprises transmitting the ULA message or the AIA message to a mobility management entity (MME) or an serving GPRS support node (SGSN). 23. The system of claim 12 wherein responding on behalf of the HSS includes sending a response to the non-EIR message indicating that access to the network is denied. 24. 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; andin 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.
