Methods, systems, and computer readable media for providing a multi-network equipment identity register

A method for providing a multi-network equipment identity register (EIR), the method comprising:

• at a node in a telecommunications network:
• receiving from a requesting entity a request to check an identity of a user equipment, the request containing the identity of the user equipment;
• querying an EIR using the identity of the user equipment;
• receiving a response from the EIR;
• and
• forwarding the response to the requesting entity,
• wherein the node includes a first interface for receiving identity check requests to check identities of user equipment in a first protocol and a second interface for receiving identity check requests to check identities of user equipment in a second protocol, such that user equipment blacklisted in a network that uses the first protocol is also blacklisted in a network that uses the second protocol.

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

• at a node in a telecommunications network:
• receiving from a requesting entity a request to check an identity of a user equipment, the request containing the identity of the user equipment;
• querying an equipment identity register (EIR) using the identity of the user equipment;
• receiving a response from the EIR;
• and
• forwarding the response to the requesting entity,
• wherein the node includes a first interface for receiving identity check requests to check identities of user equipment in a first protocol and a second interface for receiving identity check requests to check identities of user equipment in a second protocol, such that user equipment blacklisted in a network that uses the first protocol is also blacklisted in a network that uses the second protocol.
