When a Mobile Terminal (MT) leaves its Registration Area (RA) and enters into new RA, the serving Visitor Location Register (VLR) sends a registration request to the Home Location Register (HLR).On receiving this request the HLR sends a de-registration request to the old VLR (which was serving the MT).After deregistering the MT, the old VLR acknowledges the request of HLR and then the HLR confirms the registration of the MT by sending the acknowledgement message to the new VLR. This approach is called explicit deregistration scheme.
