Publication number: 20030027572Abstract: The present invention is directed to a method and system for producing and storing “roaming” area information of a mobile terminal in a home location register or guest location register. A “roaming” area includes a group of location areas within a single service area. When a mobile terminal enters a new location area within a new roaming area or enters a new service area, the home location register (HLR) or guest location register (GLR) is updated with the roaming area information of the mobile terminal. The HLR/GLR stores this information in addition to the other information typically stored for the mobile terminal. If an MSC/VLR system restart and reload occurs or another event such that the location area information is lost, the roaming area information can be retrieved from the HLR/GLR. Likewise, if the mobile terminal does not respond to a page within the location area stored for the mobile terminal, the roaming area information can be retrieved from the MSC/VLR.Type: ApplicationFiled: August 3, 2001Publication date: February 6, 2003Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Bernt Karlsson, Niklas Gustafsson

Publication number: 20030027573Abstract: A masked identification code registration system is designed to allow a user to gain an access to a content provider via a telecommunication system. The masked identification code registration system a telecommunication user database, a registration system, and a masked identification code generator by which an identification code of the telecommunication user database 8 is converted into a masked identification code, so as to enable the user to attain a masked registration in the content provider.Type: ApplicationFiled: July 31, 2002Publication date: February 6, 2003Applicant: SKYSOFT Co.,Ltd.Inventors: Ming-Long Chien, Ming-Che Lee, Chih-Yang Tai, Ming-Che Ho, Kwan-Chiun Lin

Publication number: 20030027574Abstract: One piece of information used in setting up the optimum location registration area is an area of a peripheral cell. However, in the current system, the area of a cell is set up by the predicted number of subscribers in the area, and therefore, depends on the location. For example, the areas of cells are different between a downtown and a suburban area. Therefore, when a mobile communication terminal computes the optimum location registration area, it is necessary to obtain the size information about the peripheral cell, which can cause the problem of traffic.Type: ApplicationFiled: July 9, 2002Publication date: February 6, 2003Applicant: NTT DoCoMo, Inc.Inventors: Yugo Watanabe, Masumi Fujiwara, Masami Yabusaki

Publication number: 20030027575Abstract: A mobile communication control method is provided. In the method, when a home location register receives additional service execution unsupported information from a switch in a network in a roaming destination in response to transferring subscriber information, it is determined whether location registration of a mobile station is to be performed on the basis of at least one item of information on the additional service and activation information of the additional service that are managed by a service control apparatus, and execution of location registration is controlled on the basis of a result of the determination.Type: ApplicationFiled: August 5, 2002Publication date: February 6, 2003Applicant: NTT DoCoMo, Inc.Inventors: Toru Hasegawa, Toyota Nishi, Takeshi Sugiyama, Akira Kaiyama

Publication number: 20030027576Abstract: The present invention provides a method and system for providing call recipient local information for pervasive communication devices. An originating subscriber places a call through it service provider to a receiving subscriber. Prior to connecting the call, the current time at the receiving subscriber location can be determined. The originating subscriber will be notified of the time at the subscriber's location. Based on the time at the subscriber's location and the urgency of the call, the originating subscriber can decide whether the call should be connected. Upon notifying the originating subscriber of the recipient's local time, the system can provide a prompt that allows the originating subscriber to allow connection or to defer connection. Deferring the connection can include placing the call at a more appropriate time or allowing the call to be sent to a mailbox which is associated with the receiving subscriber.Type: ApplicationFiled: July 31, 2001Publication date: February 6, 2003Applicant: International Business Machines CorporationInventors: Gregory P. Fitzpatrick, David B. Lebowitz
