Abstract: Methods, systems, and computer readable media for validating subscriber location information are disclosed. One method occurs at a network node. The method includes receiving a message containing location information associated with a subscriber. The method also includes determining whether the location information is valid based on a location validation algorithm, wherein the location validation algorithm uses prior location information associated with the subscriber in determining with the location information is valid. The method further includes performing at least one action based on the determining.

Abstract: Methods, systems, and computer readable media for providing a multi-network equipment identity register are disclosed. According to one aspect, the subject matter described herein includes a system for providing a multi-network equipment identity register. A node in a telecommunications network receives from a requesting entity a request to check an identity of a user equipment, the request containing the identity of the user equipment, queries an EIR using the identity of the user equipment, receives a response from the EIR, and forwards the response to the requesting entity. The node includes first and second interfaces for receiving requests to check an identity of a user equipment in a first and second protocol, respectively, such that a user equipment that is blacklisted in a network that uses the first protocol is also blacklisted in a network that uses the second protocol.
