Description

The present invention relates to a mobile communication system and a mobile station location management method used in the system . For example, a mobile station such as a mobile phone located in a specific location registration area in an emergency such as when a natural disaster occurs. The present invention relates to a mobile communication system suitable for quickly distributing information to a mobile station and a mobile station location management method used in the system .

  For mobile communication systems in which mobile devices such as mobile phones are wirelessly connected to perform communication, there is an increasing demand for services that distribute various types of information to mobile devices based on the location information of the mobile devices. The location information of the mobile device is managed by an HLR (Home Location Register). However, whenever the information distribution apparatus receives a request for distribution of various information from the outside, the HLR process May exceed capacity limits. In other words, since the location information managed by the HLR has a data structure using the mobile phone number as a search key, the information distribution device searches for the target mobile device using the mobile location information as a key. Therefore, since it is necessary to search the location information of all the mobile devices holding the location information, there arises a problem that it takes time to search. In addition, HLR has a limit on the number of mobile devices that can accommodate subscriber information, and it cannot accommodate subscriber information for all mobile devices in a mobile communication carrier. The subscriber information of the machine is usually distributed and accommodated in a plurality of HLRs.

  For example, as shown in FIG. 4, this type of mobile communication system includes mobile devices 1, 2, 3, base stations (radio base stations) 11, 12, 13, and MSC (Mobile Switching Center) / VLR (Visitor Location Register) / SGSN (Serving GPRS Support Node, mobile communication packet switch) 21, 22, multiple HLRs 31,..., Information distribution device 32, and information distribution request transmission device 33 It consists of and. The mobile devices 1, 2, 3 are mobile phones, for example, and are located in the location registration areas A 1, A 2, A 3, and are wirelessly connected to the base stations (radio base stations) 11, 12, 13, respectively. Base stations 11 and 12 are wired (or wireless) connected to MSC / VLR / SGSN 21, and base station 13 is wired (or wirelessly) connected to MSC / VLR / SGSN 22. The MSC / VLR / SGSN 21 is connected to the own network N1, the MSC / VLR / SGSN 22 is connected to the overseas network N2, and the own network N1 and the overseas network N2 are connected to each other. The HLRs 31,..., 31 and the information distribution device 32 are connected to the own network N1, and the information distribution request transmission device 33 is connected to the information distribution device 32. Further, the HLRs 31, ..., 31 use the information on the VLR / MSC / SGSN 21 in which the mobile devices 1 and 2 are within the jurisdiction and the information on the VLR / MSC / SGSN 22 in which the mobile device 3 is present as the location information. keeping.

  In this mobile communication system, for example, when a natural disaster occurs, an information distribution request dr for distributing information to a mobile device located in a specific location registration area is sent from the information distribution request transmission device 33 to the information distribution device 32. Sent. The information distribution device 32 accesses the HLRs 31,..., 31 to search for managed area information, and distributes the information to the corresponding mobile device.

In addition to the above mobile communication system, as this type of related technology, for example, there is an information providing service system for each user described in Patent Document 1.
In this system, an information menu center is arranged in a mobile network, and the information menu center generates an information menu to be provided to the user from the user contract information and the user location information. Location registration is performed between the mobile device and the mobile network when the mobile device is powered on or moved to the area where it is located. At this time, an individual information menu is transmitted from the information menu center to the user (mobile device). As a result, a high-quality information providing service is realized. As a result, even when the number of information providers is newly increased, an IP information service is provided only by updating the information menu, and a flexible information providing service can be operated.

  Further, in the location registration method described in Patent Document 2, an ID signal indicating a base station ID is broadcast from a base station set in a specific area in the location registration area. When the mobile station located in the base station radio zone receives the ID signal, the mobile station transmits a location registration request signal including the base station ID and the mobile station ID to the base station. In the home memory, the base station ID and mobile station ID are registered as narrow area location registration information. The IP server acquires the position related information from the position related information database and transmits it to the gateway server. The gateway server specifies a transmission target of the received position related information with reference to the home memory, and transmits the position related information to the mobile station.

  In the mobile radio communication system described in Patent Document 3, a mobile communication exchange is provided with a TLR (temporary location register). In the TLR, a location registration request from a mobile device is received, and each location registration area is stored in a memory corresponding to the identifier of the mobile device as location information of the mobile device.

  Further, in the broadcast distribution system described in Non-Patent Document 1, as shown in FIG. 5, for example, when an earthquake occurs, the Japan Meteorological Agency 41 has an earthquake early warning message (including seismic intensity information for each epicenter and region). (Dedicated protocol) is created and sent to the connected operator (phase [1]). The earthquake early warning message is received by a CBC (Cell Broadcast Center) 42 connected to the Japan Meteorological Agency 41 and analyzed. In the CBC 42, a delivery destination area is determined from the “region where strong shaking is estimated” included in the message, and a message for notifying the mobile terminal is created (phase [2]). An SGSN (Serving General Packet Radio Service Support Node) 43 has an interface with the CBC 42 and Write-Replace (message) indicating a broadcast distribution instruction on a SABP (Service Area Broadcast Protocol) including a message created by the CBC 42. Is received (phase [3]).

The SGSN 43 transmits the Write-Replace distributed from the CBC 42 to an RNC (Radio Network Controller, radio network controller) 44 that accommodates the distribution area (phase [4]). The RNC 44 that has received the Write-Replace replaces the CBS (Cell Broadcast Service) message with the BMC (Broadcast Multicast Control) protocol of the interface between the mobile terminals and distributes it to the mobile terminal 46 via the BTS (Base Transceiver Station) 45 (phase). [5]).

There is a problem. In addition, in the HLRs 31,..., The information on the VLR / MSC / SGSN in which the mobile device is located is held as the location information, but the information about the location registration area of the base station is not held. There is a problem that information cannot be distributed to the user's mobile device in registration area units.

  In addition, in the user-specific information providing service system described in Patent Document 1, a mobile device that is set in advance to request information distribution for each user is triggered by the location registration in a specific location registration area. However, it is not possible to simultaneously distribute information to mobile stations that are located in a specific location registration area at a certain point in time and subscribe to an information distribution service. For this reason, there is a problem that it is necessary to inquire the HLR in order to obtain the location registration area of the mobile device that is the target of information distribution.

  In the location registration method described in Patent Document 2, narrow location registration information is held in the home memory. However, a large number of the home memories are arranged for each region by one communication carrier, and the location registration area or the narrow location information. There is a problem in that the regional location registration information is distributed and it is difficult to quickly distribute information.

  In the mobile radio communication system described in Patent Document 3, the mobile communication exchange is provided with a TLR, and for example, there are hundreds of mobile communication exchanges installed in one telecommunications carrier in Japan. It has become. In the case of distributing information only to a specific location registration area, an information distribution request can be sent only to a specific mobile communication switch, and information can be distributed using a mobile device list in the mobile communication switch. When it is desired to distribute information in a wide range of regions and countries, mobile device lists using the location registration area as a search key are also distributed and arranged in Japan. Disadvantages of the mobile device list being distributed are that it is difficult to grasp the mobile device list in a unified manner, and at the stage of distributing information, rapid information distribution cannot be performed.

  In the broadcast distribution system described in Non-Patent Document 1, information is uniformly distributed to all mobile terminals located in a location registration area (distribution destination area) that is a target of information distribution. Therefore, the individual setting not to receive information on the mobile terminal side is possible, but it is distributed to users who do not wish to distribute information, and this broadcast distribution system is supported. There is a problem that information cannot be received unless it is a mobile terminal.

The present invention has been made in view of the above circumstances, and a mobile communication system for quickly distributing information to a mobile device such as a mobile phone located in a specific location registration area and the mobile device used in the system The purpose is to provide a location management method.
