Summary:A location registration method, apparatus, and system protects against unnecessary power waste by a mobile terminal. The location registration method includes receiving a location registration accept message from a connected network in response to a location registration request message; comparing a connected network information contained in the location registration accept message with a home network information stored in the mobile terminal; and determining, if the connected network information is different from the home network information, whether or not to perform a home network search based on a home network presence indicator contained in location registration accept message.
