Synapse's Equipment Identification Register (EIR) is a standardized node within a GSM network that is responsible for barring stolen or malfunctioning devices. The basic functionality of the EIR is to respond to the network "CheckIMEI" request by looking up the IMEI - International Mobile Equipment Identity device serial number - and responding whether to 'allow', 'monitor' or 'bar' phone service. This network element is deployed by service providers, who are looking for dense and energy-efficient solutions that can support more subscribers and services. An EIR services checkIMEI requests from wireless network elements, Mobile Switching Centers (MSC) and Serving Gateway Support Nodes (SGSN). It also allows the service providers to monitor the network, perform maintenance and support customers.
