Patent number: 7792081Abstract: The present invention provides a media independent information service (MIIS) for media independent handover (MIH) in a broadband wireless access system. A first lower entity of a mobile station receives a MIH information request primitive requesting a set of information elements provided by the MIIS from a first upper entity of the mobile station. An MIH information request message including an information query list to retrieve the set of information elements is transmitted from the first lower entity to a second lower entity of a base station. An MIH information response message including the set of information elements is received by the first lower entity from the second lower entity in response to the MIH information request message. An MIH information confirmation primitive including the set of information elements is then transmitted from the first lower entity to the first upper entity.Type: GrantFiled: April 7, 2006Date of Patent: September 7, 2010Assignee: LG Electronics Inc.Inventors: Yong Ho Kim, Yong Won Kwak, Jin Lee
