Second Exemplary Embodiment
FIG. 5 shows an example of a distribution area in the second exemplary embodiment.

  The configuration of the second exemplary embodiment is similar to that of the first exemplary embodiment.

  In FIG. 5, a communication area configured of a plurality of cells (C1 to C24) is shown. In this example, the distribution area of the emergency information transmitted by the distribution device 20 includes the cell C5 to the cell C13. The server 50A is located in the emergency information distribution area. Also, the server 50B is located outside the emergency information distribution area.

  The distribution apparatus 20 of this embodiment selects the server 50 existing in the area outside the distribution area of the emergency information when determining one server from the plurality of servers 50. In the present example, the server 50B is selected by the distribution apparatus 20 because the server 50B exists outside the distribution area of the emergency information.

  Here, when there are a plurality of servers 50 existing in the area outside the distribution area of the emergency information, the server 50 present in an area (region) farthest from the distribution area may be selected.

  The area in which the server is located may be managed in cell units, or may be managed in Paging Area (PA), Location Area (LA), Routing Area (RA) or Tracking Area (TA) units. For example, when managed in Cell units, the server 50A in FIG. 5 is treated as being located in the cell C5. Further, when managed in the paging area, assuming that the entire emergency information distribution area is the predetermined paging area 1, the server 50A is treated as being located in PA1.

  Also, the position of the server may be associated with the cell or the like by an operator or the like who installs the server. In addition, the position information acquisition device mounted on the server acquires the position information (longitude, latitude, altitude, etc.) of its own server, and based on the acquired position information, identifies the area where the own server is located, and identifies the identified position. It may be reported to a management device that manages the wireless communication system. In this case, the management device associates the reported position with the communication area.

  According to the present embodiment, the server 50 existing outside the emergency information distribution area is selected. Therefore, the server 50 existing outside the distribution area is selected as a destination to which the information of the mobile station 40 is transmitted. If the server in the area to which the emergency information is to be delivered does not operate due to unforeseeable matters, it is possible to prevent the information of the mobile station 40 from being transmitted to such a non-operational server 50. As a result, the information of the mobile station 40 can be transmitted to an appropriate destination. Also, the probability of losing information of the mobile station 40 can be reduced.

In addition, a server far from the area to which emergency information is distributed is selected. As a result, a server having a low relationship with the emergency information can be selected.
Third Exemplary Embodiment
FIG. 6 illustrates the operation of the wireless communication system in the third exemplary embodiment.

  In the exemplary embodiment described above, an example for the delivery of emergency information has been shown.

  In the above-described exemplary embodiments, the "emergency information" is, for example, information on a natural disaster or an artificial threat. Natural disaster means, for example, damage caused by storm, heavy rain, heavy snow, flood, storm surge, earthquake, tsunami, eruption and other abnormal natural phenomena. In addition, human-made disasters refer to damage caused by war (war), terrorism, riots and other human-induced causes.

  FIG. 6 shows an exemplary embodiment for searching for the position of a victim at the time of an earthquake occurrence, taking the “earthquake” of a natural disaster as a specific example among these disasters.

  The configuration of the present embodiment is basically the same as the first and second exemplary embodiments.

  The wireless communication system according to this embodiment includes a distribution source 100, a distribution device 200, a base station 300, a mobile station 400, and a position information collection server 500. The position information collection server 500 has the same function as the server 50 described above.

  In S10 of FIG. 6, the distribution source 100 transmits disaster information to the distribution device 200. The distribution source 10 is a device provided by an organization such as a local government or a government (for example, the Japan Meteorological Agency). Disaster information is emergency information such as earthquake bulletins. In the case of the 3rd Generation Partnership Project (3GPP) Earthquake and Tsunami Warning System (ETWS), disaster information is for mobile stations located in an area where P waves (Primary Wave), which are initial tremors of earthquakes, are detected. It may be information for notifying that an earthquake is imminent.

In S11, the distribution device 200 determines the position information collection server 500 after receiving the disaster information.
For example, the distribution apparatus 200 specifies a distribution area of disaster information based on the disaster information. The distribution apparatus 200 prepares (creates) a distribution request for disaster information to be transmitted to the base station in the distribution area of disaster information.
The distribution request may include the identification information of the determined position information collection server 500. Also, the identification information may be transmitted together with the distribution request as information other than the distribution request. Alternatively, the identification information and the distribution request may be transmitted at different times.
The identification information of the determined position information collection server 500 may be the address of the position information collection server. The identification information may be any one that can specify the position information collection server as the destination. For example, this address may be an Internet Protocol (IP) address or a Media Access Control (MAC) address.
The position information collecting server 500 is redundantly arranged throughout the country. The distribution apparatus 200 selects the position information collection server 500 out of the distribution area from among the position information collection servers 500 (see FIG. 5). As in the second exemplary embodiment, the location information collection server 500 most distant from the distribution area may be selected.
In the 3GPP related system, the distribution device 200 may be a cell broadcast center (CBC). Alternatively, the distribution device 200 may be a Cell Broadcast Service (CBS) server.
For example, the delivery request may be a Write-Replace Warning Request message. Also, the distribution request may be a Write-Replace message.

  In S12, the distribution apparatus 200 transmits, to the base station 300, a distribution request for disaster information (seismic warning). This distribution request is sent to the base station in the area where the disaster has occurred.

  In S13, based on the distribution request received in S12, the base station 300 broadcasts the disaster information and the identification information of the location information collection server 500 to the mobile station 400. The disaster information and the identification information may be distributed by the cell broadcast service (CBS) in units of cells of the base station 400.

In S14, when the mobile station 400 receives the disaster information and the identification information of the location information collection server 500, the mobile station 400 acquires information of the mobile station 400 according to the disaster information. In this example, the mobile station 400 that has received the earthquake bulletin starts measurement (positioning) of the current position.
In addition, positioning may be performed using Global Navigation Satellite System (GNSS).
In addition, positioning may be performed using the assist data of A-GNSS regarding A-GNSS (Assisted-Global Navigation Satellite System). The A-GNSS assist data may be received from the base station 300.

In S15, the mobile station 400 transmits the positioning result to the location information collection server address 400 indicated by the identification information received in S13.
In addition to the positioning result, the mobile station 400 also includes information on the base station 400 in the vicinity of the mobile station 400, information on a Wi-Fi (Wireless Fidelity: registered trademark) in the vicinity of the mobile station 400, and the mobile station 400. Information to be identified may be transmitted together. Here, the information for identifying the mobile station 400 may be a mobile subscriber integrated services digital network number (MSISDN), an IP address, an international mobile subscriber identity (IMSI), a temporary mobile subscriber identity (TMSI) or the like.

  After S15, the position information collecting server 500 that has received the positioning result stores (holds) the positioning result in the database. After the occurrence of a disaster, when searching for the position of the mobile station 400 at the time of disaster, the location information collection server 500 searches using information identifying the mobile station 400 as a key, and the positioning result corresponding to the mobile station 400 (mobile station 400 Identify the location information of

At S15, the mobile station 400 may transmit the accuracy information on the measurement result to the position information collecting server 500. At this time, the mobile station 400 can also transmit the identification information of the base station together with the accuracy information. For example, the identification information of the base station is, for example, Cell-ID, identification information of a Wi-Fi access point, or the like. Also, in order to calculate the Enhanced Cell-ID positioning in the location information collection server 500, it is necessary for the Enhanced Cell-ID positioning such as Physical Cell-ID, Reference Signal Received Power (RSRP), and Reference Signal Received Quality (RSRQ). Information may be included.
If the accuracy of the positioning result is low, the location information collection server 500 can perform Cell-ID based positioning or Enhanced Cell-ID positioning using the identification information of the base station transmitted from the mobile station 400. In addition, when the location information collection server 500 has a database of Wi-Fi access points, it is possible to execute Wi-Fi positioning based on Wi-Fi access point information transmitted from the mobile station 400. .

  As described above, in the present embodiment, the positioning result is transmitted from the mobile station 400 to the position information collecting server 500. That is, although the positioning is performed by the mobile station 400, it may be performed by the position information collecting server 500 as follows.

For example, the mobile station 400 can skip the positioning process of S14 after S13, and can transmit the following information to the position information collection server 500 in S15.
(1) Cell ID of base station around mobile station,
(2) Information necessary for cell positioning of PLID (Physical Location Identifier),
(3) Information necessary for E-CID (Enhanced Cell ID) positioning, or (4) information required for Wi-Fi positioning Based on at least one of the information (1) to (4) transmitted in S15 The position information collection server 500 calculates position information (for example, latitude, longitude, altitude, or a combination thereof) of the mobile station 400. The calculated position information of the mobile station 400 may be stored in a database (not shown) of the position information collection server 500.

In the present embodiment, a mechanism for knowing the position of the mobile station has been shown in order to know where the disaster victims were at the time of the earthquake. The present embodiment can be applied not only to the position of the victim but also to a mechanism for knowing the status of the victim, the peripheral information of the victim, and the like.
For example, as a state of a victim, various information regarding the victim is detected by a detection device (such as a sensor) provided in the mobile station 400. For example, biological information to be detected is a heart rate, a pulse rate, a blood pressure, a pulse or an electrocardiogram signal. Also, for example, the detected surrounding information is, for example, the temperature, humidity, wind direction, wind speed, numerical value of radiation, and the like. Also, for example, the surrounding situation of the affected person to be detected is an image or a moving image of the surrounding situation acquired by the camera of the mobile station 400 or the like.
These pieces of information are sent to the appropriate destinations. The destination may be singular or plural as long as the information can be properly processed or held.

  According to the present embodiment, at the time of disaster occurrence, the distribution device designates the position information server existing outside the area where the disaster occurred as the information distribution destination from the mobile station. Therefore, the possibility that the location information collection server data can not be referred to due to the location information database becoming involved in a disaster is reduced.

Further, according to the present embodiment, when collecting location information of the mobile station at the time of disaster to the server, the server is notified of the address of the server located in the area farthest from the disaster location. It is possible to collect location information on a server that is less likely to break. As described above, by setting the server to which the mobile station transmits location information to a location farthest from the disaster occurrence area, the probability that the location information collection server fails due to a disaster and the collected location information is lost It can be lowered. This is because the server far from the place where the disaster occurs is unlikely to be broken.
Fourth Exemplary Embodiment
FIG. 7 shows a base station and a mobile station of the wireless communication system in the fourth exemplary embodiment.

  The configuration of the exemplary embodiment of FIG. 7 is basically the same as the first to third exemplary embodiments. FIG. 7 shows the base station 310 and the mobile station 410 in the wireless communication system of this embodiment.

  The distribution device 20 or the distribution device 200 (not shown) transmits a plurality of pieces of identification information of the server 50 or the position information collection server 500 together with the emergency information (or disaster information).

  The base station 310 receives a plurality of identification information. The base station 310 transmits a plurality of identification information (addresses of respective servers in FIG. 7) to the mobile station 410.

  The mobile station 410 selects one identification information from the received plurality of identification information.

  For example, the mobile station 410 can also select identification information based on information (telephone number, TMSI, IMSI) identifying the mobile station 410. As shown in FIG. 7, the last two digits of the mobile station 410's telephone number are divided by the number of received identification information (the number of servers 50 or location information collection servers 500). The server corresponding to the remaining number in this case is selected. FIG. 7 shows the case where the last two digits of the telephone number is "14". Also, the number of identification information to be received is “3”. Therefore, when "14" is divided by "3", the remainder is "2". In the plurality of pieces of information to be received, numbers 0, 1 and 2 are respectively set. Therefore, the server corresponding to the “2” is selected. The above is an example, and the method of server selection in the mobile station 410 is not limited to this.

  Note that although a plurality of identification information is transmitted in the above, for example, identification information (addresses) of all servers outside the emergency information or disaster information distribution area may be transmitted to the mobile station 410. Good.

  Also, for example, the mobile station 410 may randomly select the identification information. For example, identification information may be randomly selected based on a predetermined random number.

According to the present embodiment, when there are a plurality of servers outside the emergency information or disaster information distribution area, concentration of load on a specific server can be suppressed. That is, it is possible to avoid the concentration of server traffic, and load distribution in the wireless communication system can be realized.
Fifth Exemplary Embodiment
FIG. 8 shows the operation of the wireless communication system in the fifth exemplary embodiment.

  In FIG. 8, the wireless communication system of the present embodiment includes a distribution source 120, a distribution device 220, a base station 320, a mobile station 420, and a server 520. The wireless communication system of the present embodiment is basically the same as the first exemplary embodiment. However, the configuration of the mobile station 420 of this embodiment is partially different.

  In S20 of FIG. 8, the mobile station 420 identifies the identification information of the server 520 existing in a predetermined area (a part of the area or the whole country) in advance and the position information of each server (for example, latitude, Hold the combination).

  At S21, the distribution source 120 transmits the emergency information to the distribution device 220.

  In S22, the distribution device 220 transmits the emergency information to the base station 320.

  At S23, the base station 320 transmits emergency information in the distribution area.

  At S24, the mobile station 420 acquires information of the mobile station 420 according to the emergency information.

  In S25, the mobile station 420 selects a server to which the acquired information of the mobile station 420 is to be transmitted. Here, from among the plurality of pieces of identification information held (registered) in advance in S20, an appropriate server existing outside the distribution area of the emergency information is selected. For example, the server located farthest from the emergency information distribution area may be selected.

  In S26, the mobile station 420 transmits the information of the mobile station 420 acquired in S24 to the server selected in S25.

  According to this embodiment, the mobile station can autonomously select a server to which the mobile station information is addressed. Thus, the mobile station can select a server that is unlikely to be destroyed by a disaster or the like.

Also, for example, since the distribution device 220 does not have to specify a server, there is no need to change the configuration of the distribution device 220.
Sixth Exemplary Embodiment
